‘Worse to come’ bushfire warning

Sunday, February 21st, 2010

Jan 6, 2010

CANBERRA – As firefighters continued to battle huge fronts in Western Australia and Tasmania yesterday, confirmation came that worse lies ahead as the nation is heated further by global warming.

The Bureau of Meteorology said Australia had been getting hotter every decade for the past 70 years and the trend was expected to continue.

Its latest climate statement said the past 10 years were the hottest decade since records began.

Last year – Australia’s second-hottest – produced record-breaking heatwaves that saw temperatures soar to 46.4C in Melbourne and forced Adelaide to endure eight consecutive days above 35C.

The Bureau of Meteorology’s annual climate statement said the mean temperature for the past 10 years had climbed 0.48C above the 1961-1990 average, climbing further last year to 0.9C above the average.

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.

Climate change impacts in our backyards: the Southwest

Friday, August 28th, 2009

The Southwestern United States

A convergence of the highest population growth rates in the nation and the most rapid warming compared with other regions makes the American Southwest especially vulnerable to climate impacts.

“The fingerprints of climate change can already be seen in both natural and managed ecosystems of the Southwest.  Future impacts on the landscape are expected to be substantial, threatening biodiversity, protected areas, and ranching and agricultural lands.”  [quotes are from the June 2009 USGCRP report, Global Climate Change Impacts in the United States].

The Southwest already experiences very high summer temperatures and corresponding water and energy needs, intensified by a rapidly growing population.  Projected temperature increases for the Southwest represent augmented stresses to health, electricity, and water supply in a region that is already at risk.  As the climate warms, the current “tug-of-war among preserving natural ecosystems, supplying the needs of rapidly expanding urban areas, and protecting the lucrative agricultural sector, will be exacerbated.”

Australians sweat out warmest winter

Thursday, August 27th, 2009

SYDNEY – Australia is in the throes of probably its warmest winter ever, with records smashed up and down the country.

Lying awake at night in pools of sweat, Australians have been wondering which hemisphere they live in.

Now the Bureau of Meteorology has confirmed that this is set to be the hottest August on record, by a big margin – and, if forecasts for the next few days are correct, the hottest winter.

The bureau, which spends much of its time dampening speculation that weather patterns have changed, issued a “special climate statement” describing the heatwave as “highly abnormal”.

It blamed hot air accumulating over central Australia during the past two or three weeks, without southerly fronts arriving to blow it away, as would usually be expected.

Nearly a dozen towns have broken winter records by more than four or five degrees, while some coastal areas of northern New South Wales and southern Queensland experienced their warmest day of 2009 in August, surpassing the midsummer temperatures of January and February.

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.”

Valley fever blowin’ on a hotter wind

Sunday, April 19th, 2009

- I pity the American Southwest where I grew up and where my older son and his family still remain.   It is squarely in the cross hairs of Global Climate Change and one only has to look at Australia to see what the future holds.   10+ million people living in the L.A. basin on what is, at bottom, simply coastal scrub desert that would barely be able to support a few tens of thousands without the massive influx of food and water delivered there daily from elsewhere.  This story about Valley Fever, is just one of many gathering force now for the Southwest.   Can you say, “Water”?

= = = = = = = – - – - – - – = = = = = = =

PHOENIX – It’s high noon, and the 112-degree summer heat – up from a decade ago – stalks Arizona’s Sonoran Desert. By late afternoon, dark clouds threaten, and monsoon winds beat the earth into a mass of swirling sand. Thick walls of surface soil blind drivers on the Interstate.

Some health experts believe new weather conditions – hotter temperatures and more intense dust storms fueled by global warming – are creating a perfect storm for the transmission of coccidioidomycosis, also known as valley fever, a fungal disease endemic to the southwestern United States.

How do cocci spores infect the body? Propelled by winds, thousands of soil particles and cocci spherules are inhaled. People – particularly those older or immune-compromised – may experience flu-like symptoms that can turn into pneumonia. If the infection disseminates, the pathogens can target any organ – mostly the nervous system, skin, bones and joints – and become life threatening.

Each year, according to the American Academy of Microbiology, about 200,000 Americans contract valley fever, and 200 of them die. But some experts believe the disease is vastly underreported. Between 1991 and 1993, healthcare costs for valley fever exceeded $66 million, according to the Pan American Center for Human Ecology and Health.

The group Physicians for Social Responsibility says global warming will multiply the incidence due to increased airborne dust and sandstorms. Higher wind speeds and drought upped Arizona’s yearly count from 33 cases of valley fever per 100,000 in 1998 to 43 per 100,000 in 2001, said Dale Griffin of the U.S. Geological Survey in St. Petersburg, Fla.

The number of cases in Arizona more than quadrupled from 1997 to 2006, according to a Mayo Clinic study. During that same period, incidence rates in California jumped from 2.5 to 8.4 cases per 100,000 people.

What will global warming look like? Scientists point to Australia

Tuesday, April 14th, 2009

“Farmers who once grew 60% of the nation’s produce are walking off their land or selling their water rights to the state and federal government. With rainfall in the region at lower than 50% of average for more than a decade, Australia is witnessing the collapse of its agricultural sector and the nation’s ability to feed itself.”

Reporting from The Murray-Darling Basin, Australia — Frank Eddy pulled off his dusty boots and slid into a chair, taking his place at the dining room table where most of the critical family issues are hashed out. Spreading hands as dry and cracked as the orchards he tends, the stout man his mates call Tank explained what damage a decade of drought has done .

“Suicide is high. Depression is huge. Families are breaking up. It’s devastation,” he said, shaking his head. “I’ve got a neighbor in terrible trouble. Found him in the paddock, sitting in his [truck], crying his eyes out. Grown men — big, strong grown men. We’re holding on by the skin of our teeth. It’s desperate times.”

A result of climate change?

“You’d have to have your head in the bloody sand to think otherwise,” Eddy said.

They call Australia the Lucky Country, with good reason. Generations of hardy castoffs tamed the world’s driest inhabited continent, created a robust economy and cultivated an image of irresistibly resilient people who can’t be held down. Australia exports itself as a place of captivating landscapes, brilliant sunshine, glittering beaches and an enviable lifestyle.

Look again. Climate scientists say Australia — beset by prolonged drought and deadly bush fires in the south, monsoon flooding and mosquito-borne fevers in the north, widespread wildlife decline, economic collapse in agriculture and killer heat waves — epitomizes the “accelerated climate crisis” that global warming models have forecast.

With few skeptics among them, Australians appear to be coming to an awakening: Adapt to a rapidly shifting climate, and soon. Scientists here warn that the experience of this island continent is an early cautionary tale for the rest of the world.

“Australia is the harbinger of change,” said paleontologist Tim Flannery, Australia’s most vocal climate change prophet. “The problems for us are going to be greater. The cost to Australia from climate change is going to be greater than for any developed country. We are already starting to see it. It’s tearing apart the life-support system that gives us this world.”

World’s water supplies at risk, UN says

Wednesday, April 8th, 2009

Surging population growth, climate change, reckless irrigation and chronic waste are placing the world’s water supplies at threat, a landmark UN report said on Thursday. Compiled by 24 UN agencies, the 348-page document gave a grim assessment of the state of the planet’s freshwater, especially in developing countries, and described the outlook for coming generations as deeply worrying.

Water is part of the complex web of factors that determine prosperity and stability, it said.

Lack of access to water helps drive poverty and deprivation and breeds the potential for unrest and conflict, it warned.

“Water is linked to the crises of climate change, energy and food supplies and prices, and troubled financial markets,” the third World Water Development Report said.

“Unless their links with water are addressed and water crises around the world are resolved, these other crises may intensify and local water crises may worsen, converging into a global water crisis and leading to political insecurity at various levels.”

The report pointed to a double squeeze on fresh water.

On one side was human impact. There were six billion humans in 2000, a tally that has already risen to 6.5 billion and could scale nine billion by 2050.

Population growth, especially in cities in poor countries, is driving explosive demand for water, prompting rivers in thirsty countries to be tapped for nearly every drop and driving governments to pump out so-called fossil water, the report said.

These are aquifers that are hundreds of thousands of years old and whose extraction is not being replenished by rainfall. Mining them for water today means depriving future generations of liquid treasure.

More Australian Weather Records Tumble

Wednesday, April 8th, 2009

The Big Dry Down Under just got a whole lot drier. The first three months of 2009 in the already parched Murray Darling basin had the least amount of rainfall since Australian weather records began 117 years ago.

This massive drainage supports $9 billion in agriculture but has been hammered by what some are calling the worst drought in 1000 years. Authorities in Australia make no bones about the cause of this freaky weather.

“We’ve had big droughts before and big floods before, but what we didn’t have was climate change,” said Rob Freeman, the chief executive of the Murray-Darling Basin Authority.

The Murray Darling is home to 2 million people who may not even have enough water to survive in the future. “I’d be loath to say that critical human needs will always be secure”, warned Freeman.

The recent rainfall record was not the only smashed. Water inputs for three-year period ending March 2009 were less than half of the previous record from the great drought of 1943-1946.
