Nature’s sting: The real cost of damaging Planet Earth

Wednesday, October 27th, 2010

You don’t have to be an environmentalist to care about protecting the Earth’s wildlife.

Just ask a Chinese fruit farmer who now has to pay people to pollinate apple trees because there are no longer enough bees to do the job for free.

And it’s not just the number of bees that is dwindling rapidly – as a direct result of human activity, species are becoming extinct at a rate 1,000 times greater than the natural average.

The Earth’s natural environment is also suffering.

In the past few decades alone, 20% of the oceans’ coral reefs have been destroyed, with a further 20% badly degraded or under serious threat of collapse, while tropical forests equivalent in size to the UK are cut down every two years.

These statistics, and the many more just like them, impact on everyone, for the very simple reason that we will all end up footing the bill.

Costing nature

For the first time in history, we can now begin to quantify just how expensive degradation of nature really is.

A recent, two-year study for the United Nations Environment Programme, entitled The Economics of Ecosystems and Biodiversity (Teeb), put the damage done to the natural world by human activity in 2008 at between $2tn (£1.3tn) and $4.5tn.

At the lower estimate, that is roughly equivalent to the entire annual economic output of the UK or Italy.

A second study, for the UN-backed Principles for Responsible Investment (PRI), puts the cost considerably higher. Taking what research lead Dr Richard Mattison calls a more “hard-nosed, economic approach”, corporate environmental research group Trucost estimates the figure at $6.6tn, or 11% of global economic output.

This, says Trucost, compares with a $5.4tn fall in the value of pension funds in developed countries caused by the global financial crisis in 2007 and 2008.

Of course these figures are just estimates – there is no exact science to measuring humans’ impact on the natural world – but they show that the risks to the global economy of large-scale environmental destruction are huge.

Government review to examine threat of world resources shortage

Thursday, June 3rd, 2010

Study commissioned following sharp rises in commodity prices on world markets and food riots in some countries

[British] Ministers have ordered a review of looming global shortages of resources, from fish and timber to water and precious metals, amid mounting concern that the problem could hit every sector of the economy.

The study has been commissioned following sharp rises in many commodity prices on the world markets and recent riots in some countries over food shortages.

There is also evidence that some nations are stockpiling important materials, buying up key producers and land and restricting exports in an attempt to protect their own businesses from increasingly fierce global competition.

Several research projects have also warned of a pending crisis in natural resources, such as water and wildlife, which have suffered dramatic losses due to over-use, pollution, habitat loss, and, increasingly, changes caused by global warming.

Nature loss ‘to damage economies’

Sunday, May 16th, 2010

The Earth’s ongoing nature losses may soon begin to hit national economies, a major UN report has warned.

Elephants The abundance of mammals, birds, reptiles and other creatures is falling rapidly

The third Global Biodiversity Outlook (GBO-3) says that some ecosystems may soon reach “tipping points” where they rapidly become less useful to humanity.

Such tipping points could include rapid dieback of forest, algal takeover of watercourses and mass coral reef death.

Last month, scientists confirmed that governments would not meet their target of curbing biodiversity loss by 2010.

“The news is not good,” said Ahmed Djoglaf, executive secretary of the UN Convention on Biological Diversity (CBD).

“We continue to lose biodiversity at a rate never before seen in history – extinction rates may be up to 1,000 times higher than the historical background rate.”

The global abundance of vertebrates – the group that includes mammals, reptiles, birds, amphibians and fish – fell by about one-third between 1970 and 2006, the UN says.

A big picture snapshot

Wednesday, December 9th, 2009

– A friend wrote me the other day about CO2 and said that most of the folks who are out there talking about CO2 and its dangers sound a bit like Chicken Little.  He said there must be places out there on the web where one can get a more balanced presentation of the issues.  And asked if I could direct him to such.

– I’m not sure I answered his questions as effectively as I might have.  I could have, for instance, done some research and tried to find web sites for him with more balanced presentations around CO2 and its issues.

– But, instead, I decided to tell him how and why the debate over CO2 has gotten to be so shrill and why many folks these days are sounding like Chicken Little.

– I think the explanation of why things have gotten so shrill is well worth repeating to a wider audience and so I’ve reproduced my friend’s questions and my responses below.

= = = = = = = = = = =   = = = = = = = = = = =   = = = = = = = = = = =

Dennis,

I know your position on global warming.   Here are my thoughts:   First any thing that would get us untangled from the Middle East and every one else that we buy oil from would be a godsend.   Most people don’t realize that Canada and Mexico are our biggest suppliers.   Being tied to any other country the way we are is a bad thing.   I don’t think the oil/coal industries will are willing to have any change in the status quo until the last ounce of oil and coal is gone.   I think they control, to one extent or another, our government.   I believe that without their influence, we would have made massive changes by now.

Now, I would like to understand more about CO2.  I am not ignorant of the chemistry or of the geological history.   My problems is when I hear the side describing the downsides of CO2 they are so one sided that they sound like Chicken Little.

Even though the CO2 increase has great potential for mass disruption of the world’s ecological balance, there must be a little of this that is being balanced by natural processes.   Perhaps,  just not at a rate that we can accept.   Could you send me some web sites with a little balance?

Dave C.

=== and my response:

Dave,

You are right.  The oil/gas/coal industries are not going to recognize the global climate change effects their products produce.   If they did, it would cost them personally a pile of money.   And yes, they do have a huge effect on governments all over the world – especially the U.S. government.

Your question about CO2 is an excellent one and I wish I could do a better job of answering it.

When you say that the people describing the coming problems from rising CO2 levels sound like Chicken Little, I have to agree.   But, you need to also reflect on how the situation got to be like that.

First off, think about the fact that scientific discoveries don’t usually come up for public debate.

And consider that science comes up with some wild and almost unbelievable discoveries fairly often.   Take Dark Matter and Dark Energy for two things.   And Quantum Physics and all of its weird ideas like entanglement and action at a distance.   And the fact that really small things like electrons are not really in one place or another but rather exist in a small cloud of probability that hovers near where we think it actually is.  And how about relativity with its ideas that time slows down as your speed get closer and closer to the speed of light?

All that stuff was discovered by science and it beggared the imagination for most of us.  But people (most of them anyway), didn’t stand up and begin to argue passionately against these new findings.

And almost EVERYTHING you and I see around us in the world today is the product of science.   Telephones, electronics, plastics, microwaves, space shuttles, nylon and the list could go on and on for years.  It is hard to find much that we use that isn’t in some way or another the direct product of science and scientific research.   Not many people will stand up and claim that the chemistry that led to developing nylon is wrong.  Or that the laws describing voltage, current and resistance are wrong.

So what’s different about science’s findings about global climate change?

Well, you already said it.   It’s the money.  It’s the vested interests.  It’s what folks will stand to lose if the theories about CO2 and global climate change are true.  And it is big.  If this stuff is true, it means nothing less than that we have to simply reorganized how we do business on this Earth.  Almost everything about how most of us live is going to have to change some if we want to continue to live on this planet without turning it into a hell.

So, that’s a big big change that will result if we listen to what the scientists are saying.  It’s going to cost big oil/gas/coal billions of dollars.  It’s going to change the geopolitical balance between nations, it’s going to mean that ordinary folks like you and I and Joe Six-pack are all going to have to do things differently.

But nobody likes to lose money, nobody likes to lose political power and nobody likes to change their familiar and comfortable life-style.   Joe Six-pack doesn’t want to hear that his big two smoke-stack turbo diesel truck is bad for the planet and we can’t afford to have it running around any more.  The folks making money cutting down the Amazon rain forest don’t want to hear it.  The fishermen fishing the fish in the sea into extinction don’t want to hear it.   The folks buying cheap shit at Wal-Mart, don’t want to hear it.

And that brings these findings of the scientists right smack up against human nature.

And that human nature doesn’t want to change and it will begin to squirm and look for every reason and excuse it can to dodge the bullet and to avoid having to change, or lose money or whatever it is.

When the scientists decided that 70% of the entire universe was made of dark matter a few years ago, no one demonstrated in the streets or began to talk against it on the Rush Limbaugh show.   It didn’t get into anyone’s back pocket – so they didn’t care.

But CO2 and Global Climate Change is going to get into all our back pockets – big time.

Let me take you back and give you some history.   I learned what I’m going to tell you from a book entitled, Red Sky at Morning by Gustave Speth.

In the 1970’s, environmentalists in the U.S. were just beginning to push their efforts to get laws passed like the Clean Air Act and the Food and Drug Laws.  The public was mildly interested and industry was ignoring all of it.   Then Three Mile Island and a few other things all happened at about the same time and suddenly the public was very hot to support environmental protection laws.  The result was that a lot of laws about protecting the air and the water and such were all passed at once before the industry folks were really awake to what was happening.

Industry lost a lot of money because of all of these new laws and they vowed to never be asleep at the wheel again.

About 10 years later, in the 1980’s, the environmentalists began to realize that they could not protect the entire world by just passing good laws in the U.S.   They needed to expand their efforts and begin to fight for environmental protection laws that would be international in scope.  By the early 90’s the alarms were being sounded that we needed to do some things internationally or we, as a species, and as a planet, were going to have big problems.

But this time industry was not asleep.   They’d been burned once by not paying attention.   Now, every time an effort was mounted to increase environmental protection globally, industry looked at the proposed laws and if they could see that such a law was going to cost them big money, they mobilized to confuse people and to prevent the political will from developing to pass such a law.

This cat and mouse game has been going on for two decades now.   At first the scientists simply published the results of the scientific research in papers.  They trusted that people would be smart enough to see the writing on the wall.   But, industry confused people and confused the issues.  They published counter studies that seemed to show the opposite conclusions.

So scientists and environmental activists began to talk louder trying to get their messages and warnings out.  And industry fought back harder.  And the entire thing escalated up and up.

Most scientists now think that the entire “Global Climate Change is because of CO2” issue has been definitively proven over and over beyond the shadow of any doubt.   But the public doesn’t think that.   They are still deeply confused by the mis-information industry has been putting out for just that purpose – to confuse them and to therefore prevent political will from developing that could result in some real laws getting passed.

What’s going on in Copenhagen now is a great example.   Many people think that awareness of our environmental problems has finally gotten to the point where the world’s leaders might actually come together and try to do something real to prevent a major environmental and climate disaster.   And then, two weeks before the conference, the other side unleashes a major campaign to throw doubt on the scientific conclusions and to mess the entire conference up.

And, I fear, they are doing a pretty good job.   Frankly, I think we’re toast and I’ve thought so for a long time.   Human nature is just too predictable and to easily manipulated.   Those who want to convince the public that the climate science is wrong actually have a pretty easy time of it because Joe Six-pack and folks like him would prefer to believe that nothing’s going on because it is way easier than thinking about the fact that they might have to change their consumerist lifestyles.

So yeah, some folks are sounding like shrill Chicken Littles.  Why?  Because it is a damn desperate situation and the world is likely to go into the toilet in spite of the very best efforts of the environmentalists.  And they are worried about it.

After reading over what I’ve written here, I realize that I’ve only partially answered what you actually asked.  You asked for some balance on the question of how CO2 is processed by the environment.

There are a lot of answers to that because, as you can imagine, the world’s climate and biosphere is a wickedly complex system.   But, here are a few of the high points:

– The level of CO2 in the atmosphere hasn’t been this high in 6 million years.

– The current swift rise in the level of CO2 in the atmosphere is faster than anything we can see in the climate records back for 6 million years.

– This rise corresponds with the rise of industrial civilization.   It begins in the climate record just about the time industrialization began when the English started building factories in the 1840’s or so and it increases in the climate record in pace with the increasing rise in industrial production.

– The denialists say that the rise in CO2 is a natural thing and has nothing to do with the CO2 humans are putting into the air.   I find that an amazing idea.   It’s like saying, “I just tromped down on the gas pedal and now the car is going really fast.”   And then having someone tell you that it’s just a coincidence and that the gas pedal has nothing to do with the acceleration.  Yeah, right.

– Nature does have some ability to absorb excess CO2.  The ocean absorbs a lot of it.  But, it cannot keep up with the rate we’re adding it to the air.   And, as the ocean absorbs it, the water becomes more acidic.  As it becomes more acidic, it makes it harder for ocean animals that have shells to make their shells because the acidification interferes with their chemistry.  At some point, this rise in dissolved CO2 is really going to mess with some huge food chains in the ocean.

– Plants and trees like CO2 and use and absorb it.  To a point.  Add a little more CO2 and a little more heat and they thrive.    But, add a bit more and they begin to weaken and wilt and their ability to absorb CO2 lessens.   This is true for the majority of plants and trees.   There are some exceptions but they are a minority and what really matters is what the majority of the world’s plants and trees are likely to do.  And what they are likely to do it not good.

– Big coal has been yammering on for years about CO2 sequestration.  But, in spite of many big public relations splashes, no one yet has made a full scale carbon sequestration plant that works.   In the mean time, China is building one or more coal fired dirty power production plants a week!   Much of the public thinks “clean coal” is either a done deal or very close.   It truth, it is miles and mile off and maybe we’ll never have it.

– The problem is bigger that just how much CO2 we’re putting into the air.  That’s bad and we can see it ramping up.  But, it is causing other problems much as one fire creates others as the embers fly.

– The arctic ice is melting and as it does, the white snow and ice disappear and the darker sea and land underneath become visible.  The white reflected heat back into space.   The darker stuff being exposed absorbs it.  So there’s more heating going on because of this and it, in turn, causes more ice and snow to melt.  It is a positive feed back cycle and it is beginning to get up onto legs of its own.

– Glaciers all over the world, with very few exceptions, are melting.  The winter snow falls that used to stay in the mountains and then melt in the summer are going away and that’s going to have a huge impact on human beings.  The summer water that millions need to grow crops and survive is going away, soon.  We’re talking most of the west coast of South America, the Southwestern U.S., Northern India and a huge swath across Central China from east to west.  We’ve never seen anything like the disruption and starvation that will result.

Dave, I’ve been reading this stuff for years and this is just a part of what I’ve read.  Scientists have no reason to make this stuff up.  But, folks who make big big bucks by keeping the world running as it is now have a huge motivation to not see and react to the coming global climate changes.  These folks have a lot of money and they think that even if there are big problems, they will have to money to hang out in nice villas up in the Alps and where ever while the rest of use starve and fight it out in the streets.

All they have to do is keep us confused so we won’t shut their party down.

Got Gas?

Sunday, October 18th, 2009

– A good friend of mine sent me this article saying, “Interesting article on natural gas“.

– It is, indeed, an interesting article but I saw it in a different light than many perhaps do.

– My response to my friend:

D,

An interesting and potentially game-changing story, indeed.

But, it is a classic case of humanity’s inborn tendency to jump at the short term relief without fairly balancing it against the long-term consequences.

To see the consequences, I’d like to see someone make the assumption that ALL the fossil fuel we burn from here forward is this cleaner gas.   And, to be really fair, we can drop all considerations of the collateral damages associated with obtaining the gas that were mentioned in the article.

Just assume that the world will continue growing and producing and have more babies and all the rest of it for the next 20 to 50 years – all largely fueled by this gas.

The analysis should show what will happen to the CO2 levels in the atmosphere from consuming just this gas.  And then it should consider the consequences of this change in CO2 levels on global weather, ecosystems, environmental refugees, depleted glaciers and winter snow packs, increasing desertification, species die-offs and an entire host of follow-on consequences that will attend continued rising of global CO2 levels.

Short-term thinkers are enthusiastic about these new gas producing technologies because they allow us, for the moment, to avoid having to deal with the really tough long term questions regarding what we have to do to get into a sustainable long-term homeostatic balance with the planet’s ecosphere.

Long term, it’s really the only question that matters much.

Everything else is an avoidance or a denial that only take us further down the road wherein we do not solve this problem and cause a major crater in the Earth’s evolutionary history; killing many species, altering the weather for tens of thousands of years and killing the majority of the human beings alive and reducing the ones that survive to miserable circumstances.

Not an insignificant outcome – and all the more terrible because, difficult as it may be, we could avoid most of it if we had the grit and the will to do so.

Global Warming – and denial

Sunday, October 11th, 2009

We watched a segment on 60 Minutes last night about how much worst forest fires have gotten in the Western U.S, in the last 10 to 20 years.   They were interviewing the fellow who is the top firefighter after working his way up from the lines for 30 years – a guy who’s seen it all first hand.

He said that a decade ago, of they had a fire over 100,000 acres, it was big news.   Now, we had two at over 500,000 acres last year and one of those was over 600,000 acres.   The fires are so big and the resources so small to fight them, that they have to let many of them just burn and the only time they will really focus and fight is if a town is under threat.

They asked him, directly, if he thought Global Warming was a factor in all of this and he said it would be hard to find a man on the front lines fighting these fires who doesn’t think so.   He also said that high fire season has increased by 78 days per year and that fires in the high mountain areas are much more common because the higher temperatures are drying things out now that used to remain damp and incombustible for a much long part of the year.   Some of the forests that are burning are burning so thoroughly that they will not be back in our life times.   And that in 100 years, half of the forest in the western U.S. that’s standing now – could be gone.

Deniers ought to take a look at this piece.  These are not pointy-headed intellectuals from the universities talking here.   these are the folks who are looking at and fighting the consequences of the climate change happening around us everyday.  Chilling stuff.

Beetles, wildfire: Double threat in warming world

Friday, August 28th, 2009

HAINES JUNCTION, Yukon Territory (AP) — A veil of smoke settled over the forest in the shadow of the St. Elias Mountains, in a wilderness whose spruce trees stood tall and gray, a deathly gray even in the greenest heart of a Yukon summer.

“As far as the eye can see, it’s all infested,” forester Rob Legare said, looking out over the thick woods of the Alsek River valley.

Beetles and fire, twin plagues, are consuming northern forests in what scientists say is a preview of the future, in a century growing warmer, as the land grows drier, trees grow weaker and pests, abetted by milder winters, grow stronger.

Dying, burning forests would then only add to the warming.

It’s here in the sub-Arctic and Arctic — in Alaska, across Siberia, in northernmost Europe, and in the Yukon and elsewhere in northern Canada — that Earth’s climate is changing most rapidly. While average temperatures globally rose 0.74 degrees Celsius (1.3 degrees Fahrenheit) in the past century, the far north experienced warming at twice that rate or greater.

In Russia’s frigid east, some average temperatures have risen more than 2 degrees Celsius (3.6 degrees Fahrenheit), with midwinter mercury spiking even higher. And “eight of the last 10 summers have been extreme wildfire seasons in Siberia,” American researcher Amber J. Soja pointed out by telephone from central Siberia.

Along with shrinking the polar ice cap and thawing permafrost, scientists say, the warming of the Arctic threatens to turn boreal forest — the vast cover of spruce, pine and other conifers blanketing these high latitudes — into less of a crucial “sink” absorbing carbon dioxide and more of a source, as megatons of that greenhouse gas rise from dead, burning and decaying wood.

American forest ecologist Scott Green worries about a “domino effect.”

“These things may occur simultaneously,” said the researcher from the University of Northern British Columbia. “If the bark beetles kill the trees, you’ll have lots of dead, dry wood that will create a really, really hot fire, and then sometimes you don’t get trees regenerating on the site.”

North America faces beetle plague

Sunday, July 26th, 2009

A plague of tree-killing beetles which swept across British Columbia is threatening to spread to the US.

The mountain pine beetle has killed more than half of all lodge pole pine in the province and is now active in neighbouring Alberta.

Cold winters usually kill off the beetle larvae, but the region has been warmer than usual in recent years.

Scientists say the beetle could attack and kill jack pines, which are found throughout North America.

An introduction to global warming impacts: Hell and High Water

Tuesday, April 21st, 2009

– This is a great place to start if you want to get the big overview of Global Climate Change and its consequences.   And recall that this, as big as it is, is only a part of the bigger picture that I’ve been calling The Perfect Storm.

= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

In this post, I will examine the key impacts we face by 2100 if we stay anywhere near our current emissions path. I will focus primarily on:

  • Staggeringly high temperature rise, especially over land — some 15°F over much of the United States
  • Sea level rise of 5 feet, rising some 6 to 12 inches (or more) each decade thereafter
  • Dust Bowls over the U.S. SW and many other heavily populated regions around the globe
  • Massive species loss on land and sea — 50% or more of all life
  • Unexpected impacts — the fearsome “unknown unknowns”
  • More severe hurricanes — especially in the Gulf

Equally tragic, as a 2009 NOAA-led study found, these impacts be “largely irreversible for 1000 years.”

Biofuels Could Hasten Climate Change

Tuesday, April 21st, 2009

A new study finds that it will take more than 75 years for the carbon emissions saved through the use of biofuels to compensate for the carbon lost when biofuel plantations are established on forestlands. If the original habitat was peatland, carbon balance would take more than 600 years.

The oil palm, increasingly used as a source for biofuel, has replaced soybean as the world’s most traded oilseed crop. Global production of palm oil has increased exponentially over the past 40 years. In 2006, 85 percent of the global palm-oil crop was produced in Indonesia and Malaysia, countries whose combined annual tropical forest loss is around 20,000 square kilometers.

Conversion of forest to oil palm also results in significant impoverishment of both plant and animal communities. Other tropical crops suitable for biofuel use, like soybean, sugar cane and jatropha, are all likely to have similar impacts on climate and biodiversity.

“Biofuels are a bad deal for forests, wildlife and the climate if they replace tropical rain forests,” says research scientist Finn Danielsen, lead author of the study. “In fact, they hasten climate change by removing one of the world’s most efficient carbon storage tools, intact tropical rain forests.”

As countries strive to meet obligations to reduce carbon emissions under one international agreement (Kyoto Protocol), they may not only fail to meet their obligations under another (Convention on Biological Diversity) but may actually hasten global climate change.

According to the study, reducing deforestation is likely to represent a more effective climate-change mitigation strategy than converting forest for biofuel production, and it may help nations meet their international commitments to reduce biodiversity loss.
