– I am constantly embarrased by my country’s position on climate issues.   Is it that we, the United States, really believe that the rest of the world is wrong and we are the only ones who really understand the climate issues?   Or are we just  overwhelmed by our own arrogance and crippled by the pervasive power of the oil, gas and coal industries?

——————————————-

Negotiators from the United States are trying to weaken the language of a climate change declaration set to be unveiled at next month’s G-8 summit of the world’s leading industrial powers, according to documents obtained yesterday by The Washington Post.

A draft proposal dated April 2007 that is being debated in Bonn, Germany, this weekend by senior officials of the Group of Eight includes a pledge to limit the global temperature rise this century to 3.6 degrees Fahrenheit, as well as an agreement to reduce worldwide greenhouse gas emissions to 50 percent below 1990 levels by 2050.

The United States is seeking to strike that section, the documents show.

Many scientists have warned that an increase of more than 3.6 degrees this century could trigger disastrous consequences such as mass extinction of species and accelerated melting of polar ice sheets, which would raise sea levels.

The documents show that American officials are also trying to eliminate draft language that says, “We acknowledge that the U.N. climate process is the appropriate forum for negotiating future global action on climate change.” Industrial and developing countries have used the United Nations as the forum for crafting climate agreements for years.

– Recently, Samadhisoft (this Blog) and Immigration Orange, cross linked. This kind of cross linkage is important because it increases readership for everyone and it plays strongly to the idea that data should be set free by opening as many pathways for it as we can.

– These cross linkages have additional benefits as well. I generally cruise the Blogs this Blog’s cross linked with periodically to see what they are Blogging about. We tend to focus in the same general areas of interest but the world is big and sometimes they pick up on something I’ve missed and vice-versa.

– Well, today, I found a real plum over at Kyle de Beausset’s Blog, Immigration Orange. It’s an absolutely must see video about the data that lies hidden in the world’s publically owned and paid for databases. Some of the graphics are stunning – not for their beauty but, rather, for their implications and the insights they give into our world.

– Great stuff! Thanks, Kyle!

Police are facing calls for an independent inquiry after CCTV footage showed a police officer repeatedly punching a woman during an arrest.

Toni Comer, 20, was being arrested last July for damaging a car in Sheffield – an offence she has since admitted.

Her lawyer called for an Independent Police Complaints Commission inquiry.

Police said they would investigate a complaint by Ms Comer but they were “happy” with the officer’s conduct. He said he had been trying to subdue her.

The footage, obtained by the Guardian newspaper and shown on BBC Two’s Newsnight, shows Ms Comer and a police officer falling down a flight of stairs outside Sheffield’s Niche nightclub.

At the bottom, she is restrained by a group of officers, with the officer she fell with punching her five times – although it is not clear on what part of her body.

I woke up this morning to find another 9 inches had fallen overnight. Amazing weather we’re having. Luckily, we are blessed with great staff here. My foreman, Jesus, and Dino were out most of the night clearing snow from the greenhouses so that they won’t collapse from the weight.

I bought them some coffee from the local Starbucks and while they were winding down after a long night, I went in and roused Sharon from her slumbers and she and I went out with long bamboo poles and began to clear snow from the trees and shrubs. The stuff that fell was thick and heavy and many trees were down from the weight.

This afternoon, the skys were clear and I expect it’ll be cold tonight. Good – anything but more snow!

– I’ve come across this phrase a few times so I decided to look it up and I found the following:

——————————–

A Just So Story is any proposed explanation meant to account for a phenomenon (often animal characteristics), which consistently lacks any sort of physical evidence or ability to be verified by current or future data. Just So Stories are often fantastic and so improbable so as to border on absurdity.

“Just So Stories” are a perennial feature of pseudoscientific writings in order to shore up the arguments of pseudoscientists. Some examples include L. Ron Hubbard’s claim that humans evolved from alien clams, or Immanuel Velikovsky‘s statement that Venus was a comet that erupted from the bowels of Jupiter.

The term is most commonly, but often inappropriately, used in the contexts of evolutionary psychology, sociobiology, and evolutionary anthropology, typically applied to a postulated evolutionary mechanism for a human or animal trait or behavior which cannot be falsified by scientific evidence.

Occasionally the term is used more broadly for any fantastic or improbable explanation of a phenomenon (particularly animal characteristics) which lacks an evidentiary basis. The name comes from the title of Rudyard Kipling’s Just-So Stories For Little Children, originally published in 1902. The stories themselves were sometimes interpreted as mockery of Lamarck’s theory of the inheritance of acquired characteristics as, for instance, when elephants were said to have acquired trunks because one had its nose stretched by a hungry crocodile.

– Indeed, this will not be an easy read. Not that anything in it is so deeply intellectual or mathematical – it’s not. But, it is long and will take some concentration. I first saw the video presentation of this material a few months ago and was rather stunned at the author’s assertion and that it was so obviously true.

– This has to do with the mathematics of anything that grows steadily – like if you have money in the bank at 5% interest. Most of us think we understand the concept well. Well, after you read this, you will probably discover otherwise and the world will look a bit different. Enjoy, or at least persevere.

Dr. Albert Bartlett: Arithmetic, Population and Energy (transcript)

Professor Emeritus of Physics University of Colorado, Boulder

Thank you very much Hugh.

It’s a great pleasure to be here, and to have a chance just to share with you some very simple ideas about the problems we’re facing. Some of these problems are local, some are national and some are global.

They are all tied together, they’re tied together by arithmetic and the arithmetic isn’t very difficult. What I hope to do is I hope to be able to convince you that the greatest shortcoming of the human race is our inability to understand the exponential function.

Well, you say, what’s the exponential function?

This is a mathematical function that you’d write down if you’re going to describe the size of anything that was growing steadily. If you had something that was growing at 5% per year, you’d write the exponential function to show how large that growing quantity was year after year. And so we are talking about a situation where the requirements required for the growing quantity to increase by a fixed fraction is a constant 5% per year. The 5% is a fixed fraction, the three years a fixed length of time. So that’s what we want to talk about. Its just ordinary steady growth.

Well if it takes a fixed length of time to grow 5%, it follows it takes a longer fixed length of time to grow 100%. That longer time’s called the doubling time and we need to know how you calculate that doubling time. It’s easy.

You just take the number 70, divide it by the percent growth per unit time and that gives you the doubling time. So our example of 5% per year, you divide that into 70, you find that growing quantity will double in size every 14 years.

Well, you might ask, where did that seventy come from, well, the answer is that it’s approximately one hundred multiplied by the natural logarhythm of two. If you wanted the time to triple you would use the natural log rhythm of three. So it’s all very logical. But you don’t have to remember where it came from, just remember 70.

I wish we could get every person to make this mental calculation every time we see a percent growth rate of anything in a news story. For example, if you saw a story that said things had been growing at 7% per year for several recent years, you wouldn’t bat an eyelash. But when you see a headline that says crime has doubled in a decade you say, my heavens what’s happening.

Ok what is happening? Seven percent growth per year, divide the seven into seventy, the doubling time is ten years. But notice if you want to write a headline to get people’s attention, you’d never write, crime is growing at seven percent per year, no body would know what it means. Now, do you know what seven percent means?

Let’s take an example, another example from Colorado, the cost of an all day lift ticket to ski at Vale. It’s been growing about seven percent per year ever since Vale first opened in 1963. At that time you paid $5 for an all day lift ticket. What’s the doubling time for seven percent growth? Ten years. So what was the cost ten years later in 1973, ten years later in 1983 and ten years later in 1993, what was it in 2003, and what do we have to look forward to? (Audience laughter)

This is what 7% means. Most people don’t have a clue. And how is Vale doing? They are pretty much on skip.

Let’s look at a generic graph of something that is growing steadily. After one doubling time the growing quantity is up to twice its initial size, two doubling times, it’s up to four times its initial size, then it goes to 8-16-32-64-128-256-512, in ten doubling times it’s a thousand times larger than when it started. You can see if you try to make a graph of that on ordinary graph paper the graph is going to go right through the ceiling.

Now let me give you an example to show the enormous numbers you can get with just a modest number of doublings.

Legend has it that the game of chess was invented by a mathematician who worked for a king. The king was very pleased, he said, “I want to reward you”. The mathematician said ” My needs are modest, please take my new chess board and on the first square place one grain of wheat, on the next square double the one and make two, on the next square double the two and make four, just keep doubling until you’ve doubled for every square, that would be an adequate payment”. We can guess the king thought this a foolish man. “I was ready to give him a real reward; all he asked for was just a few grains of wheat”.

But let’s see what is involved in this; we know there are 8 grains on the forth square. I can get this number ‘eight’ by multiplying three twos together. Its 2x2x2, its one two less than the number of the square, now that continues in each case. So on the last square, I find the number of grains by multiplying 63 two’s together.

Now let’s look at the way the totals build up. When we add one grain on the first square, the total on the board is one. We add two grains that makes a total three. We put on four grains, now the total is seven. Seven is a grain less that eight, it’s a grain less than three two’s multiplied together. Fifteen is a grain less than four two’s multiplied together. That continues in each case, so when were done, the total number of grains will be one grain less than the number I get multiplying 64 two’s together. My question is how much wheat is that?

You know, would that be a nice pile here in the room? Would it fill the building? Would it cover the county to a depth of 2 meters? How much wheat are we talking about?

The answer is that it’s roughly four hundred times the 1990 world wide harvest of wheat. That could be more wheat than humans have harvested in the entire history of the earth. You say, how did you get such a big number and the answer is, it was simple. We just started with one grain, but we let the numbers grow steadily till it had doubled a mere 63 times.

Now there’s something else that is very important, the growth in any doubling time is greater than the total of all the preceding growth. For example, when I put eight grains on the 4th square the eight is larger than the total of seven that were already there. I put thirty two grains on the 6th square; the thirty two is larger than the total of thirty one that were already there. Every time the growing quantity doubles, it takes more than all you’d used in all the proceeding growth.

Well, let’s translate that into the energy crisis. Here is an add from the year 1975, it asks the question could America run out of electricity? America depends on electricity; our need for electricity actually doubles every 10 or 12 years. That’s an accurate reflection of a very long history of steady growth of the electrical industry in this country. Growth of a rate around 7% per year which gives you doubling every 10 years.

Now with all that history of growth, they just expect that growth will go on forever. Fortunately it stopped, not because anyone understood arithmetic, it stopped for other reasons. Well, let’s ask what if. Suppose the growth had continued then we would see here the thing we just saw with the chess board. In the ten years following the appearance of this ad, in that decade, the amount of electrical energy we would have consumed in this country would have been greater than the total of all the electrical energy we had ever consumed in the entire proceeding history of the steady growth of that industry in this country.

Now did you realise that anything as completely acceptable as 7% growth per year could give such an incredible consequence, that in just ten years you’d use more than the total of all that had been used in all the proceeding growth?

Well that’s exactly what President Carter was referring to in his speech on energy. One of his statements was this. He said, in each of those decades more oil was consumed than in all of humankind’s pervious history. By itself it’s a stunning statement.

Now you can understand that the president was telling us the simple consequences of the arithmetic of 7% growth each year in world oil consumption, and that was the historic figure up until the 1970’s.

There’s another beautiful consequence of this arithmetic. If you take seventy years as a period of time and note that that’s roughly one human lifetime, then any percent growth continued steadily for seventy years gives you an overall increase by a factor that’s very easy to calculate. For example 4% per year for 70 years, you find the factor by multiplying four two’s together it’s a factor of 16.

A few years ago, one of the newspapers of my hometown of Bolder Colorado, quizzed the nine members of the Bolder City Council and asked them what rate of growth was Boulders population. You’d think it would be good to have in the coming years. Well the nine members of the Boulder City council gave answers ranging from a low of 1% per year, now that happens to match the preset rate of growth of the population of the United States. We are not at zero population growth, right now, the number of Americans increases every year by over three million people. No member of the council said Boulder should grow less rapidly than the United States is growing.

Now the highest answer any council member gave was 5% per year. You know I felt compelled, I had to write them a letter and say did you know that 5% per year for just 70 years – I can remember when just 70 years seemed like an awful long time, it just doesn’t seem so long now. (audience laughter). Well that means Boulders population would increase by a factor of 32, and that is for today. We have one over loaded sewer treatment plant, in seventy years we will need 32 overloaded sewer treatment plants.

Now did you realise anything as completely all American as 5% growth per year could give such an incredible consequence in such a modest period of time? Our city council people have zero understanding of this very simple arithmetic.

Well, a few years ago, I had a class of non science students, who were interested in problems of science and society; we spent a lot of time learning to use semi logarithmic graph paper. It’s printed in such a way that these equilaterals( 09:53)*** on the vertical scale each represent an increase by a factor of 10. So you go from one thousand to 10 thousand to a hundred thousand, and the reason you use this special paper is that on this paper a straight line represents steady growth.

Now we worked on a lot of examples, I said to the students lets talk about inflation, let’s talk about 7% per year. It wasn’t this high when we did this, it’s been higher since then, fortunately it’s lower now. And I said to the students, as I say to you, you have roughly sixty years life expectancy ahead of you, lets see what some common things will cost if we had sixty years of 7% annual inflation.

The students found that a 55cents gallon of gasoline would cost $35.20 – $2.50 for a movie would be $160. The $15 sack of groceries my mother used to buy for doallar and a quarter, that will be $960. A thousand dollar suit of clothes $6,400 a $400 automobile will cost a quarter of a million dollars and a $45,000 home will cost nearly three million dollars.

Well I gave the students this data, (shows overhead) these cam from a blue cross, blue shield ad, the add appeared in Newsweek magazine and gave these figures to show the cost escalation of gall bladder surgery in the year since 1950, when that surges cost $361. I said make a semi logarithmic plot, let’s see what’s happening. The students found the first four points lined up on a straight line whose slope indicated inflation of about 6% per year, but the fourth, fifth and sixth where on a steeper line almost 10% inflation per year. Well, then I said to the students, run that steeper line on out to the year 2000, lets get an idea of what a gall bladder operation might cost, 2000 was four years ago, the answer is $25,000. The lesson there was awfully clear. If you’re thinking about gall bladder surgery do it now. (audience laughter)

In the summer of 1986 the news reports indicated that the world population had reached the number of five billion people growing at the rate of 1.7% per year. Well your reaction to 1.7% might be to say that that’s so small nothing bad could ever happen at 1.7% per year. So you calculate the doubling time you find its only 41 years, now that was back in 1986, more recently in 1999 we read that the world population had grown from five billion to six billion . The good news is that the growth rate had dropped from 1.7% to 1.3% per cent per year. The bad news is that in spite of the drop in the growth rate, the world population today is increasing by about 75 million additional people every year.

Now, if this current modest 1.3% per year could continue, the world population would grow to a density of one person per square meter on the dry land surface of the earth in just seven hundred and eighty years and then the mass of people would equal the mass of the earth in just twenty four hundred years. Well we can smile at those, we know they couldn’t happen. This one make for a cute cartoon, the caption says, “Excuse me sir, but I am prepared to make you a rather attractive offer for your square”.

There’s a very profound lesson in that cartoon. The lesson is that zero population growth is gonna happen. Now we can debate whether we like zero population growth or don’t like it, its going to happen whether we debate it or not, whether we like it or not. It’s absolutely certain people could never live at that density on the dry land surface of the earth. Therefore today’s high birth rates will drop; today’s low death rate will rise till they have exactly the same numerical value. That will certainly be in a time shorter than several hundred years. So maybe you’re wondering then, what options are available if we wanted to address the problem.

In the left hand column I’ve listed some of those things we should encourage if we want to raise the rate of growth of population and in so doing make the problem worse. Just look at the list. Every thing in the list is as sacred as mother hood, there’s immigration, medicine, public health, sanitation. These are all devoted to the humane goals of lowering the death rate and that’s very important to me, if it’s my death they are lowering. Then I’ve got to realise that anything that just lowers the death rate makes the population problem worse.

There’s peace, law and order, scientific agriculture has lowered the death rate due to famine that just makes the population problem worse. It’s widely reported that the 55 mph speed limit saved thousands of lives that just makes the population problem worse. Clean air makes it worse.

Now in this column are some of the things we should encourage if we want to lower the rate of growth of the population and in so doing help solve the population problem. Well, there’s abstention, contraception, abortion, small families, stop immigration, disease, war, murder, famine, accidents. Now smoking clearly raises the death rate, will that help solve the problem?

Remember our conclusion from the cartoon of one person per square meter; we concluded that zero population growth is gonna happen. Lets state that conclusion in other terms and say its obvious nature is going to choose from the right hand list and we don’t have to do anything except be prepared to live with whatever nature chooses from that right hand list. Or we can exercise the one option that’s open to us, and that option is to choose first from the right hand list. We gotta find something here we can go out and campaign for. Anyone here for promoting disease? (Audience laughter)

We now have the capabilities of incredible war, would you like more murder, more famine, more accidents? Well, here we can see the human dilemma, every thing we regard as good makes the population problem worse, everything we regard as bad, helps solve the problem. There is a dilemma if ever there was one.

The one remaining question is education, does it go on the left hand column or the right hand column. I’d have to say thus far in this country it’s been in the left had column and it’s done very little to reduce the ignorance of the problem. So where do we start. Well, let’s start in Bolder Colorado, here in my home town. Here is the 1950’s census figure, the1960, -1970 in that period of twenty years the average growth rate of Boulders population was 6% per year. With big efforts, we’ve been able to slow the growth somewhat. There’s the year 2000 census figure. I’d like to ask people, let’s start with that 2000 figure go another 70 years, one human life time, and ask, what rate of growth would we need in Boulders population in the next seventy years so that the end of seventy years the population of Boulder would equal today’s population of your choice of major American cities?

Boulder in seventy years could be as big as Boston is today if we just grew 2.58% per year. Now if we thought Detroit was a better model we would have to shoot for 3.1/4% per year. Remember the historic figure on the preceding slide 6% per year. If that could continue for one life time, the population of Boulder would be larger than the population of Los Angeles. Well, I’ll just tell you, you couldn’t put the population of Los Angles in the boulder valley, therefore its obvious. Boulders population growth is going to stop and the only question is will we be able to stop it while there is still some open space or will we wait until its wall to wall people and we’re all chocking to death?

Now, every once in a while someone says to me, you know a bigger city just might be a better city and I have to say, wait a minute, we’ve done that experiment already. We don’t need to wonder what will be the affect of growth on Boulder because Boulder tomorrow can be seen in the Los Angles of today, and for the price of an airplane ticket we can step seventy years into the future and see exactly what its like. What is it like? Here’s an interesting headline from Los Angeles. (Shows slide) Maybe that has something to do with this headline from Los Angles. (Shows slide)

So how are we doing in Colorado? Well, we’re the growth capital of the USA today and proud of it. The Rocky Mountain News tells us to expect another million people in the front range in the next 20 years, and what are the consequences of all this? They are totally predictable and no surprises, we know exactly what happens when you crowd more people into an area.

Well as you can imagine growth control is very controversial and I treasure the letter from which these quotations are taken. Now this letter was written to me by a leading citizen of our community. He’s a leading proponent of controlled growth, controlled growth just means growth. This man writes “I take no exception to your arguments regarding exponential growth; I don’t believe the exponential argument is valid at the local level.”

So you see, arithmetic doesn’t hold in Boulder. (Audience laughs) I have to admit that man has a degree form the University of Colorado; it’s not a degree in mathematics in science or in engineering. Alright, let’s look now at what happens when we have this kind of steady growth in a finite environment.

Bacteria grow by doubling. One bacterium divides to become two, the two divide to become 4, become 8, 16 and so on. Suppose we had bacteria that doubled in number this way every minute. Suppose we put one of these bacterium into an empty bottle at eleven in the morning, and then observe that the bottle is full at twelve noon. There’s our case of just ordinary steady growth, it has a doubling time of one minuet, and it’s in the finite environment of one bottle. I want to ask you three questions.

Number one; at which time was the bottle half full? Well, would you believe 11:59,one minuet before 12, because they double in number every minute.

Second Question; if you were an average bacterium in that bottle at what time would you first realise that you were running of space? Well let’s just look at the last minute in the bottle. At 12 noon its full, one minute before its half full, 2 minutes before its ¼ full than 1/8th than a 1/16th . Let me ask you, at 5 minutes before 12 when the bottle is only 3% full and is 97% open space just yearning for development, how many of you would realise there’s a problem?

Now in the ongoing controversy over growth in Bolder, someone wrote to the newspaper some years ago and said look, there’s no problem with population growth in Boulder, because the writer said, we have fifteen times as much open space as we’ve already used. So let me ask you what time was it in Boulder when the open space was fifteen times the amount of space we had already used? And the answer is, it was four minutes before 12 in Boulder valley. Well suppose that at 2 minutes before 12, some of the bacterium realised they were running out of space, so they launch a great search for new bottles. They searched offshore and on the outer continental shelf and the overthrust belt and the Artic, and they find three new bottles. Now that’s an incredible discovery, that’s three times the total amount of resource they ever new about before, they now have four bottles, before their discovery they had one. Now surely this will give them a sustainable society, wont’ it?

You know what the third question is? How long can the growth continue as a result of this magnificent discovery? Well look at the score, at 12 noon, one bottles filled, there are three to go, 12:01 two bottles are filled, there’s two to go and at 12:02 all four are filled and that’s the end of the line. Now you don’t need any more arithmetic than this to evaluate the absolutely contradictory statements that we’ve all heard and read from experts who tell us in one breath we can go on increasing our rates of consumption of fossil fuels and then in the next breath don’t worry, we will always be able to make the discoveries of new resources that we need to meet the requirement of that growth.

Well a few years ago in Washington our energy secretary observed that in the energy crisis we have a classic case of exponential growth against a finite source. So let’s look now at some of these finite sources. We turn to the work of the late Dr M. King Hubbert, he’s plotted here a semi logarithmic graph of world oil production. You can see the lines been approximately straight for about 100 years, clear up here to 1970, average growth rate very close to 7% per year. It’s logical to ask how much longer can that 7% growth continue. That’s answered by the numbers in this table (shows slide). The numbers in the top line tell us that in the year 1973, world oil production was twenty billion barrels, the total production in all of history, three hundred billion, the remaining reserves, seventeen hundred billion.

Now those are data, the rest of this table is just calculated out assuming the historic 7% growth continued in the years following 1973 exactly as it had been for the proceeding one hundred years. Now in fact the growth stopped, it stopped because OPEC raised their oil prices so we’re asking here, what if? Suppose we just decided to stay on that 7% growth curve, let’s go back to 1981, by 1981 on the 7% curve, the total usage in all of history would add up to five hundred billion barrels, the remaining reserves, fifteen hundred billion. At that point the remaining reserves are three times the total of every thing we have used in all history. That’s an enormous reserve, but what time is it when the remaining reserve is three times the total of all you’ve used in all of history? The answer is its two minutes before twelve.

We know with 7% growth, the doubling time is 10 years. We go from 1981 to 1991, by 1991 on the 7% curve, the total usage in all of history would add up to a thousand billion barrels, there would be a thousand billion left. At that point the remaining oil would be equal in quantity to the total of everything we’ve used in the entire history of the oil industry on this earth. One hundred and thirty years of oil consumption. You’d say, That’s an enormous reserve, but what time is it when the remaining reserves is equal to all you’ve used in all of history? The answer is its one minute before twelve. So we go one more decade to the turn of the century, that’s like right now, that’s when 7% would finish using up the oil reserves of the earth.

So let’s look at this in a very nice graphical way. Suppose the area of this tiny rectangle represents all the oil we used on this earth before 1940, then in the decade to the 40’s we used this much, that’s equal to all that had been used in all of history. In the decade of the 50’s we used this much, and that’s equal to all that had been used in all of history. In the decade of the 60’s we used this much, again that’s equal to the total of all the proceeding usage. Here we see graphically what president Carter told us. Now if that 7% growth had continued through the 70’s. 80’s and 90’s there’s what we mean. That’s all the oil there is.

Now there’s a widely held belief that if you throw enough money at holes in the ground oil is sure to come up. Well there will be discoveries in new oil and maybe major discoveries, but look, we would have to discover this much new oil if we would have that 7% growth continue ten more years. Ask yourself, what do you think is the chance that oil discovered after the close of our meeting today will be in an amount equal to the total of all we’ve known about in all history. Then realise if all that new oil could be found that would be sufficient to let the historic 7% growth continue ten more years. Well it’s interestingly to see what the experts say.

Here’s from an interview in Time magazine, an interview with one of the most widely quoted oil experts in all of Texas, they asked him, “but haven’t many of our bigger fields been drilled nearly dry”? He responded saying “there’s still as much oil to be found in the US as has ever been produced” Now lets assume he’s right. What time is it? And the answer is, one minute before twelve. I’ve read several things this guy’s written; I don’t think he has any understanding of this very simple arithmetic.

Well in the energy crisis about thirty years ago we saw ads such as this (shows slide) This is from the American Electric Power Company, it’s a bit reassuring, sort of saying, now don’t worry to much because we’re sitting on half of the worlds known supply of coal enough for over 500 years. Where did that 500 year figure come from? It may have had its origin in this report to the committee on Interior and Insular Affairs of the United States Senate, because in that report we find this sentence “at current levels of output***** (27.23) these American coal reserves can be expected to last more than 500 years”

This is one of the most dangerous statements in the literature. It’s dangerous because its true, it isn’t the truth that makes it dangerous, the danger lies in the fact that people take the sentence apart, they just say coal will last 500 years. They forget the caveat with which the sentence started. Now what were those opening words, “at current levels”, what does that mean? That means if, and only if we maintain zero growth of coal production.

So let’s look at a few numbers. We go to the annual energy review, published by the dept of energy (DOE). They give this as a coal demonstrated reserve base in the United States, it has a footnote that says about half the demonstrated reserve base is estimated to be recoverable. You can not recover and get out of the ground and use 100% of the coal that’s there. So this number then, is ½ of this number. We will come back again to those in just a moment. The report also tells us that in 1971 we were mining coal at this rate, twenty years later its at this rate, put those numbers together and the average growth rate of coal production in that twenty years is 2.86% per year. And so we have to ask, well, how long would a reserve last if you have steady growth in the rate of consumption until the last bit of it is used.

I’ll show you the equation here for the expiration time. I’ll tell you it takes first year college calculus to derive that equation, so it can’t be very difficult. You know I have a feeling there must be dozens of people in this country who’ve had first year college calculus, but let me suggest, I think that equation is probably the best kept scientific secret of the century!

Now let me show you why, if you used that equation to calculate the life expectancy of the reserve base, or the one half they think is recoverable for different steady rates of growth, you’ll find if the growth rate is zero, the small estimate would go about 240 years and the large one would go close to 500 years. So that report to the congress was correct. But look what we get if we plug in steady growth. Back in the 1960’s it was our national goal to achieve growth of coal production up around 8% per year. If you could achieve that and continue it, coal would last between 37 – 46 years. President Carter cut that goal roughly in half, hoping to reach 4% per year if that could continue coal would last between 59-75 years. Here’s that 2.86%, the average for the recent period of twenty years, if that could continue coal would last between 72-94 years. That’s within the life expectancy of children born today. The only way you are going to get any where near this wild quote, this 500 year figure, is to be able to simultaneously do two highly improbable things.

Number one, you got to figure out how to use 100% of the coal that is in the ground. Number two, you got to figure out how to have 500 years of zero growth of coal production. Look at those figures, those are facts.

Back in the 1970’s there was great national concern about energy. But these concerns disappeared in the 80’s, now the concerns about energy in the 70’s prompted experts, journalists, and scientist to assure the American people that there was no reason to be concerned. So let’s go back now and look at some of those assurances from the 70’s so we can see what to expect now that the energy crisis is returning.

Here is the director of the energy division of the Oakridge National laboratory telling us how expensive it is to import oil, telling us we must have big increases and rapid growth in our use of coal. Under these conditions, he estimates America’s coal reserves were so huge they can last a minimum of three years, probably a maximum of a thousand years. You’ve just seen the facts, now you see what an expert tells us and what can you conclude? There was a three hour television special on CBS on energy, the reporter said; by the lowest estimate we have enough coal for 200 years, by the highest, enough for more than a thousand years. You’ve just seen the facts now you can see what a journalist tells us after careful study, and what can you conclude?

In the journal of Chemical education, on the page for high school chemistry teachers in an article by the scientific staff of the journal, they tell us our proven coal reserves are enormous and they give a figure. These can satisfy present US energy needs for nearly a thousand years. Well, let’s do long division. You take the coal they say is there and divide by what was then the current rate of consumption, you get 180 years. Now they didn’t say, current rate of consumption, they said present US energy needs. Coal today supplies about one fifth, about 20% of the energy we use in this country, so if you’d like to calculate how long this quantity of coal can satisfy present US energy needs, you have to multiply this denomination by five. When you do that you get thirty six years. They said nearly a thousand years. Newsweek magazine, in a cover story on energy, said, at present rates of consumption we have enough coal for 666.5 years, the point 5 means they think it will run out in July instead of January. (audience laughter)

If you round that off, and say roughly 600 years, that’s close enough to 500 to lie within the uncertainty of our knowledge of the size of the reserves. So with that observation that’s a reasonable statement, but what this lead into was a story about how we have to have major rapid growth in coal consumption. Well its obvious isn’t? If you have the growth that they re writing about, it won’t last as long as they said it would last with zero growth. They never mention this. I wrote them a long letter, told them I thought it was a serious misrepresentation to give readers the feeling we could have all this growth that they were writing about and still have coal around for 600 years. I got back a nice form letter; it had nothing to do with what I’d tried to explain to them.

I gave this talk at a high school in Omaha, and after the talk the high school physics teacher came to me, and he had a booklet, and he said have you seen this, and I hadn’t seen it, and he said look at this, we’ve got coal coming out of our ears, as reported by Forbes magazine, that’s a prominent business magazine, the United States has 437 billion tons of coal reserves. That is a good number; this is equivalent to a lot of BTU’s or its enough energy to keep 100 million large generating plants going for the next 800 years or so. And the teacher said to me, how can that be true, that’s one large electric generating plant for every two people in the United States. I said of course it can’t be true, its absolute nonsense. Let’s do long division to see how crazy it is. So you take the coal they say is there, divide by what was then the current rate of consumption, you find you couldn’t keep that up for 800 years and we hardly at that time had 500 large electric plants, they said it would be good for a hundred million such plants.

Time magazine tells us that beneath the pit heads of Appalachia in the Ohio valley and under the sprawling strip mines of the west lie coal seams rich enough to meet the countries power needs for centuries, no matter how much energy consumption may grow. So I give you a very fundamental observation, don’t believe any perditions of the life expectancy of a non renewable resource until you have confirmed the prediction by repeating the calculation. As a colliery we have to note that the more optimistic the prediction the greater is the probability that it is based on faulty arithmetic or on no arithmetic at all.

Again from Time Magazine, energy industries agree that to achieve some form of energy self sufficiency the US must mine all the coal that it can. Now think about that for just a moment. Let me paraphrase it. The more rapidly we consume our resources the more self sufficient we will be. Isn’t that what it says?

David Bower calls this the policy of strength to exhaustion. Here’s an example of strength to exhaustion. Here is William Simon, energy advisor to the president of the United States, Simon says we should be trying to get as many holes drilled as possible, to get the proven oil reserves. The more rapidly we can get the last of that oil up out of the ground and finish using it, the better off we’ll be.

So let’s look at Dr Hubberts graph for the lower 48 states in oil production, again its semi logarithmic. Here we have a straight line section of steady growth, but for quite a while now production has fallen below the growth curve while our demand continued on up this graph curve until the 1970’s. It’s obvious the difference between the two curves has to be made up with imports. It was in early 1995 that we read that the year 1994 was the first year in our nation’s history in which we had to import more oil than we were able to get of our own ground.

Well, maybe you’re wondering, does it make any sense to imagine that we can have steady growth with a rate of consumption of a resource till the last bit of it was used, then the rate of consumption would plunge abruptly to zero. I say no, that doesn’t make sense. Okay, you say, why bother us with the calculation of this expiration time, my answer is this. Every segment of our society, our business, leaders government leaders, political leaders, at the local level, state level, national level, everyone aspires to maintain a society in which all measures of material consumption continue to grow steadily year after year after year; a world without end.

Since that’s so central to every thing we do, we ought to know where it would lead. On the other hand we should recognise there’s a better model and again we turn to the work of the late Dr Hubbert. He’s plotted the rate of consumption of resources that have already expired, he finds yes, there’s is an early period of steady growth, and a rate of consumption. But then the rate goes through a maximum and comes back down in a nice cemetric bell shape curve. Now when he did this some years ago and fitted it to the oil production in the US, he found at that time we were right there. We were at the peak; we were halfway through the resource, that’s exactly what that Texas expert said that I quoted a minute ago.

Now let’s see what it means. It means that from now on domestic oil production can only go down hill and its down hill all the rest of the way and it doesn’t’ matter what they say inside the beltway in Washington DC.

Now it means we can work hard and put some bumps on the down hill side of the curve, you’ll see there’s bumps on the uphill side. The debate is heating up over drilling in the Artic wildlife refuge. I’ve seen the estimate that they might find 3.2 billion barrels of oil up there. 3.2 billion is the area of that little tiny square; that’s less than one years consumption in the United States. So let’s look at the curve in this way, the area under the total curve that represents a total resource in the United States. It’s been divided into three parts, here is the oil we’ve taken from the ground, we’ve used it, its gone. This vertical shaded band, that’s the oil we’ve drilled into; we’ve found it, were pumping on it today. Shaded in green on the right is the undiscovered oil. We have very good ways now of estimating how much oil remains undiscovered. This is the oil we gotta find if were going to make it down the curve on schedule. Now every once in a while somebody says to me, but you know, a hundred years ago somebody did a calculation and predicated the US would be out of oil in 25 years, the calculation must’ve been wrong, therefore, of course, all calculations are wrong. Let’s understand what they did. One hundred years ago this band of discovered oil was over in here some where (points to slide), all they did was to take the discovered oil divide it by how rapidly it was being used and came up with 25 years. They had no idea then how much oil was undiscovered. Well it’s obvious; you got to make a new calculation every time you make a new discovery. We’re not asking today how long will the discovered oil last, we’re asking about the discovered and the undiscovered, we’re now talking about the rest of the oil. What does the US geological survey tell us?

Back in 1984 they said the estimated US supply from undiscovered resources and demonstrated reserves were thirty six years at present rates of production or nineteen years in the absence of imports. Five years latter in 1989, that thirty six years is down to thirty two years, the nineteen years down to sixteen years. So the numbers are holding together as we march down the right hand side of Hubbert’s curve.

Well every once in awhile we run into somebody who says we shouldn’t worry about the problem, we can solve it. In this case we can solve it by growing corn, distilling it in ethanol, and run all the vehicles in the United States on ethanol. Lets just look what he says, he says today ethanol production displaces over 43 ½ million barrels of imported oil annually. That sounds pretty good doesn’t it, until you think. First question you have to ask. Forty three and a half million barrels, what fraction is that of US vehicle consumption in a year. The answer is its 1%.

You would have to multiply corn production devoted to ethanol by a factor of 100 just to make the numbers look right. There isn’t that much total agricultural land in the United States. There’s a bigger problem. It takes diesel fuel to plough the ground to plant the corn to make the fertiliser to make the corn grow, to tend the corn, to harvest the corn. It takes more energy to distillate it, you finally get a gallon of ethanol, you will be lucky if there’s as much energy in the gallon as it took to produce it. In general it’s a looser. But this guy says not to worry; we can solve it that way.

Back in 1956, Dr Hubbert addressed a convention of petroleum geologists and engineers. He told them that his calculations led him to believe that the peak of US oil and gas production could be expected to occur between 1966 – 1971, no one took him seriously. So let’s see whats happened. The data here is from the Department of Energy, DOE. Here is steady growth; here is 1956, when Dr Hubbert did his analysis. He said at that time that peak would occur between 1966-1971. There’s the peak, 1970. It was followed by a very rapid decline. Then the Alaskan pipeline started delivering oil, and it was a partial recovery. That production has now peaked and every things going down hill in unison in the right hand side of the curve. And when I go to my home computer to figure out the parameters of the curve, that’s the best fit to the data, from that fit it looks to me that we have consumed ¾ of the recoverable oil that was ever in our ground in the United States and we are now coasting down hill on the last 25% of that once enormous resource. So we have to ask about world oil.

Dr Hubbert in 1974, predicted that the peak of would oil would occur around 1995, so lets see what’s happened. Here we have the data from the Department of energy (DOE). A long period of steady growth, there’s quite a big drop there, and then there was a speedy recovery, then an enormous drop and a very slow recovery. Those drops are each due to a price hike from OPEC. Well it’s clear we’re not yet over the peak, so when I now go to fit the curve, I need one more bit of information before I can do the fit. I have to got to the geology literature and ask the literature what do you think is the total amount of oil we will ever find on this earth. The consensus figure in the literature is two thousand billion barrels. Now that’s quite uncertain, plus or minus, maybe 40 -50%. If I plug that in and do the fit, the peak is this year. (2004) If I assume there is 50% more than the consensus figure the peak moves back to 2019. If I assume there’s twice as much as the consensus figure, the peak moves back to 2030.

So no matter how you cut it, in your life expectancy, you are going to see the peak of world oil production. You’ve got to ask yourself, what is life going to be like when we have declining world production of petroleum and we have a growing world population and we have a growing world per capita demand for oil. Think about it.

In the March 1998 issue of the Scientific American, there was a major article by two real petroleum geologists, they said this peak would occur before 2010, so we are all in the same ball park. Now that article in Scientific American triggered a lot of discussion. Here is an article in Fortune magazine, Nov, 1999, talking about oil forever, and in that article we see a criticism of the geologist’s analysis, and this is from an Emirates Professor of economics at MIT. And he said this analysis by the geologists is a piece of foolishness, the world will never run out of oil, not in 10,000 years. So let’s look at what’s been happening.

Here we have two graphs, on one scale, we have here in the bar graph graphs that’s the annual discovery of oil each year, here is the annual production of oil each year. Notice since the 1980’s we’ve been producing about twice as much as we’ve been finding. Yet you’ve seen and read and heard statements from PhD’s and non scientists saying that we have greater resources of petroleum now than ever before in history. What in the world are they smoking?

Now here is another look at world oil production, but this is per capita. This is litres per person each day. There is two litres, a litre is about a quart, and so two litres is about ½ gallon. The upper curve assumes there was no growth in the world population since 1920, that it stayed fluid at 1.8 billion. This then is just a copy of that earlier curve. The lower curve uses the actual population of the world and what you find is that with a growing world population this curve is pulled down more and more as you go farther to the right. And notice that peak is at about 2.2 litres per person a day in the 1970’s. It is now down to about 1.7 litres a person a day, so we can say that on any day any one of us uses more than 1.7 litres of petroleum directly or indirectly, we’re using more than our share. Just think about what that means.

Well, we do have to ask about new discoveries. Here is a discussion from about eleven years ago about the largest discovery of oil in the Gulf of Mexico, in the past twenty years an estimated seven hundred million barrels of oil. That’s a lot of oil, but a lot compared to what? At that time we were consuming 16.6 million barrels every day in the United States. Divide the 16.6 into seven hundred and you’d find that discovery would meet US needs for forty two days.

On the front page of the Wall Street Journal, we read about the new Hibernia oil field off the south coast of Newfoundland. Please read this one line in the headline ” Now it will last fifty years” That gives you some kind of a feeling for what amount of oil may be out there, so lets follow up and read from that story in the Wall Street Journal. “The Hibernia field, one of the largest oil discoveries in North America in decades, should deliver its first oil by the end of the year. At least 20 more fields may follow offering well over one billion barrels of high quality crude providing a steady flow of oil, just a quick tanker away from the energy thirsty east coast”.

So let’s do some arithmetic. We take the amount of oil that we think is up there, a billion barrels. At that time the US consumption has grown to about 18 million barrels a day, divide the 18 million into the one billion and you would find that would meet US needs for fifty six days.

Now what was the impression you had from that line in the headline in the Wall Street Journal? And as you think about this, think about the definition of modern agriculture (*****48.13) use of land to convert petroleum into food and we can see the end of the petroleum.

Dr Hubbert testified before a committee of the congress, he told them that the exponential phase of the industrial growth which has dominated human activities during the last couple of centuries is now drawing to a close. Yet during the last two centuries of unbroken industrial growth we have evolved to what amounts to an exponential growth culture. I would say it’s more than a culture it’s our national religion, because we worship growth. Pick up any newspaper; you’ll see headlines such as this, “State forecasts robust growth.”

Have you ever heard of a physician diagnosing a cancer in a patient and telling the patient you had a robust cancer. It isn’t just in the United States that we have this terrible addiction, the Japanese are so accustomed to growth that economists in Tokyo usually speak of a recession any time the growth rate dips below 3% per year.

So, what do we do?

In the words of Winston Churchill, “sometimes we have to do what is required.” First of all as a nation we have to get serious about renewable energy. For a start we ought to have a big increase in the funding for research in the development and dispersion of renewable energy. We have to educate all of our people to understand the arithmetic and the consequences of growth, especially in terms of populations and in terms of the earth’s finite resources. We must educate people to recognise the fact that growth in rates of population and growth in rates of consumption of resources can not be sustained. What’s the first law of sustainability? You’ve heard thousands of people talking endlessly about sustainability; did they ever tell you the first law? Here it is, population growth and/or growth in the rates of consumption of resources cannot be sustained. That’s simple arithmetic Yet nobody that I’m encountering will tell you about that when talking about sustainability. So I think it’s intellectually dishonest to talk about saving the environment, which is sustainability, without stressing the obvious facts that stopping population growth is a necessary condition for saving the environment and for sustainability.

We must educate people to see the need to examine carefully the allegations of the technological optimist who assure us that science and technology will always be able to solve all of our problems of population growth, food, energy and resources.

Chief amongst these optimists was the late Dr Julian Simon, formerly professor of economics and business administration at the University of Illinois, and later the university in Maryland. With regard to copper, Simon has written that we will never run out of copper because copper can be made from other metals. The letters to the editor jumped all over and told him about chemistry, but he just brushed it off, “don’t worry he said if its ever important we can make copper out of other metals.

Now Simon had a book that was published by the Princeton University press. In that book he’s writing about oil form many sources including bio mass and he says clearly there are not many ***51:33? for this source except for the sun energy. He goes on to note but even if our sun was not so vast as it is, there well may be other suns elsewhere. Well Simons right, there are other suns elsewhere, but the question is, would you base public policy on the belief that if we need another sun we will figure out how to go get it and haul it back into our solar system.

Now you cannot laugh, for decades before his death, this man was a trusted policy advisor at the very highest levels in Washington DC. Bill Moyes interviewed Ivan Kasanof, he asked Kasanof what happens to the idea of the dignity of the human species if this population growth continues and Kasanof Says, it’ll be completely destroyed.

I’d like to use what I call my bathroom metaphor. If two people live in an apartment, and they had two bathrooms then they both have freedom of the bathroom. You can go to the bathroom anytime you want, stay as long as you want, for whatever you need, and everyone believes in the freedom of the bathroom. It should be right there in the constitution. But if you have twenty people in the apartment and two bathrooms, then no matter how much every person believes in the freedom of the bathroom, there is no such thing. You have to set up times for each person; you have to bang on the door, aren’t you through yet and so on. Kasanof concluded with one of the most profound observations I’ve seen in years, he says, in the same way, democracy can not survive over population. Human dignity can not survive over population. Convenience and decency cannot survive over population. As you put more and more people into the world, the value of life not only decline it disappears. It doesn’t matter if some one dies, the more people, there are the less one individual matters. And so, central to the things that we must do is to recognise that population growth is the immediate cause of all our resource and environmental crisis.

And in the last one hour the world population has increased by about ten thousand people and the population of the United States has increased by about two hundred and eighty people. And so to be successful with this experiment of human life on earth, we have to understand the laws of nature, as we encounter them in the study of science and mathematics. We should remember the words of Aldous Huxley that “facts do not cease to exist because they’re ignored”. We should remember the words of Eric Severson; he observed that the chief source of problems is solutions. This is what we encounter everyday, solutions to problems just make the problems worse. We should remember the message of this cartoon “thinking is very upsetting, it tells us things we’d rather not know” We should remember the words of Galileo; he said “I do not feel obliged to believe that the same god who has endowed us with sense, reason and intellect has intended us to forgo their use”. If there is one message it is this. We can not let other people do our thinking for us.

Now, except for those petroleum graphs the things I’ve told you are not predictions of the future, I’m only reporting facts, and the results of some very simple arithmetic. I do with confidence that these facts, this arithmetic and more important our level of understanding of them, will play a major role in shaping our future. Now, don’t take what I’ve said blindly or uncritically, because of the rhetoric, or for any other reason. Please, you check the facts; please check my arithmetic, if you find errors please let me know. If you don’t find errors, then I hope you’ll take this very very seriously.

Now you are important people because you can think. If there’s anything that is in short supply in the world today its people who are willing to think. So here’s a challenge. Can you think of any problem, on any scale, from microscopic to global, whose long term solutions is in any demonstratable way, aided, assisted or advanced by having larger populations in our local levels, state levels, national level, or global level? Can you think of anything that can get better if we crowd more people into our cities, our towns, into our state our nation or on this earth?

Now I’ll close with these words from the Late reverend Martin Luther King Jnr who said, unlike the plagues of the dark ages, our contemporary diseases, which we do not yet understand, the modern plague of over population is solvable with means we have discovered and with resource we posses. What is lacking is not sufficient knowledge of the solution, but universal consciousness of the gravity of the problem and the education of the billions who are its victims.

So I hope I’ve made a reasonable case for my opening statement, that I think the greatest shortcoming of the human race is our inability to understand this very simple arithmetic.

Thank you very, very much.

– A few days ago, I received an E-mail discussing “Key Bumping”. It said that many common locks could be opened with a special key and a simple technique. Then a linked YouTube video showed how it was done. Frankly, I was a bit doubtful that the whole subject might be a hoax so I fired off an E-mail to the snopes people ➡, the folks who report on the truth or falsity of various urban legends. I’ve often received an amazing E-mail warning of claim from one friend or another, gone to Snopes to check it out, and had to write back to my sincere but slightly gullible freind that they’d been had. It’s a good site – check it out.

Well, after a few days, Snopes published a report on the Key Bumping matter ➡ and it turns out that it is true which is both amazing and worrying to me – and it should be to you as well.

Here’s some text from security.org ➡ to give you the drift:

A “999” or bump key can be any key that fits a particular pin tumbler lock and that has been modified so that all of its cuts (or grooves) are made to the deepest allowable position as defined by each manufacturer. The term “fit” means that the key will enter the keyway (the front of the lock) but will not unlock it. For example, assume all of the locks in a particular apartment complex are produced by the same manufacturer and have the same keyway. The key for apartment 101 can enter the lock of apartment 207 (or any other apartment) but will only unlock the apartment for which it was cut (i.e., apartment 101). Any key cut for any apartment in this example could be modified to act as a bump key and then could be used to open any other apartment within the complex (or potentially any other complexes where the same manufacturer’s locks were installed).

The term “bumping” refers to the process of forcing the key to interact with the pin tumblers by “bumping” or rapping it with a plastic mallet while it is inserted into the lock. This process entails hitting the head of the key, causing it to rapidly move forward. When the key is struck correctly, each of the bottom pins is “bumped” upward for a brief instant, thus allowing the lock to be opened.

– I came across a page of links to nothing but blogs that focus on Science. It’s a treasure trove.  Here’s a link to the list of links: ➡

Enjoy.
