Greenpeace Helps Remind Us That Some Still Believe Polar Bears Not In Danger From Global Warming

The image above is from an excellent video clip of a January 31 stunt by the good folks at Greenpeace. I am aware that some find the methods and tactics of the environmental advocacy group Greenpeace objectionable. Nevertheless, they are peaceful and effective. Generally, I support them with a smile, as in this case.

A prime example of their methods is the aforementioned video, which is linked below. You see, despite the fact that 2007 was the second-warmest year on record and that the permanent ice pack, which is the foundation of polar bear habitat, withstood unprecedented melting, some people, including government officials, still declare polar bears not in danger from global warming.

Eventual Polar Bear Extinction Among Consequences of Polar Ice Melting In Northern Canada

Last time, I showed you a brief but important video about the type of peaceful protest needed to prevent the loss of more polar ice and eventual polar bear extinction. Lest my writings seem alarmist, let us take a sober examination of the problem.

If you didn't have a chance to watch it, the video points to a failure on the part of the government of the United States to list the polar bear as an endangered species.

Why is that a problem? The initial answer may seem obvious. Polar bears are endangered. However, there’s another reason of equal importance. Without global cooperation to reduce greenhouse gas emissions, we cannot fix the problem. By extension, since polar bears live in northern Canada as well as Alaska, the Canadian government has an equal responsibility to act.

Sadly, our friends to the north are correct in one element of their justification for deferring action. Canadians produce much less pollution than their Yankee neighbors so they should not be compelled to act until the government of the United States does.

Consequences of Polar Ice Melting in Northern Canada Visible From Tundra Buggy In Churchill, Manitoba

Last month, I had the distinct privilege of attending the third International Solar Cities Congress in the charming city of Adelaide, along Australia’s south coast. The event was tremendous and several of my upcoming threads here on KBC will be inspired from the many revelations I had during my time Down Under.

Among the most fascinating was related by Gary Doer, Premier of Manitoba, Canada. In his remarks, Mr. Doer illustrated beautifully the contemporary effects of global warming and the consequences of polar ice melting in northern Canada.

Churchill, Manitoba is among the most accessible locations for viewing polar bears. Because these majestic beasts can kill a person with one swat of their front paws, it is necessary to enter their habitat in a tundra buggy as pictured above. It is, in essence, a mobile entertainment venue suitable for the harsh weather conditions and strong enough to protect its occupants from excessive bear inquisitiveness or aggression.

In Northern Hemisphere, Melting of Polar Ice Well Ahead of Many Predictions – Next Month Could See Ice-Free Arctic

There’s an old saying which some believe originated as a Chinese curse: May you live in interesting times. The new millennium certainly qualifies! It often seems that the weather has become our worst enemy. If I were a polar bear, I know that I’d feel that way.

So far this month, I’ve been telling you about the significance of proclamations about global warming which have emerged from the scientific community this year. The news is not good. In fact, it’s horrible. All peer-reviewed predictions about the causes and effects of global warming are coming to fruition and it may well happen that next month, summertime melting of polar ice in the Northern Hemisphere will be complete. We could have an ice-free Arctic for the first time in the history of humankind.

That’s a very big deal. In fact, some of the more conservative estimates by very respected academic bodies gave us until 2050 before we’d see a completely ice-free Arctic, even in summer. They were way off. Why? Was there a flaw in their interpretation? Could it be that atmospheric carbon content is not the best measure of the doom we have leveled on ourselves?

Complete Loss of Multi-Year Arctic Ice Portends Faster Arrival at Ice-Free Arctic

In July of 2008, I warned of the arrival in just a few years of an ice-free Arctic due to continued acceleration of greenhouse gas production in the United States and around the world. This past winter, we saw many regions of the Northern Hemisphere experience unseasonably cold temperatures which led some global warming skeptics to doubt the phenomenon with greater passion.

Fortunately, science won the argument yet again with NASA’s explanation of the global warming hole. So, where does the science of global warming lie today? Well, NASA’s explanation of the global warming hole was helpful but many skeptics were unswayed by NASA’s scientific conclusions. In fact, the inability of some skeptics to understand how abnormally cold temperatures in a single region can be unrelated to the larger, global move toward a warmer future has stymied some environmentalists. Hence, science must intensify its message yet again.

In recent days, European scientists from INSU-CNRS completed a broad, comprehensive study of Arctic sea ice in an attempt to lay to rest once and for all the debate about the melting of polar ice during years when the Northern hemisphere experiences particularly frigid winters. They conducted literally thousands of examinations of core samples of Arctic sea ice. Sadly, their persuasive conclusions point toward a very bleak future:

• Transpolar drift has accelerated greatly (10% per decade) over the past century, indicating a loss of depth and stability of the permanent ice shelf.

• The mean deformation rate of polar ice has increased by half in recent years, both summer ice and winter ice.

• Summer ice no longer remains solid for 3 years. In other words, all of the ancient sea ice in the Arctic has melted. Everything which we see there is new. This is arguably the most damning statistic of all because it concludes that the abnormally cold winter of 2009 was inadequate to save ice from as recently as 3 years ago.

In conclusion, the number of convincing arguments against the causes and effects of global warming continues to dwindle right along with the thickness and lifespan of Arctic sea ice. We now can witness with our own eyes just how quickly the Arctic will be ice-free in the summer. Perhaps most frightening of all is the possibility that it will occur this year. For all our sakes, not to mention the fate of the polar bear, I hope that it does not happen.

New Climate Change Report from Federal Government Explains Loss of Ambassador Species

On June 16, the government of the United States released its landmark report,
Global Climate Change Impacts in the United States.
While coming up short in
several key areas, most notably the exclusion of

Dr. James Hansen
who no doubt would have refuted every point which does not
call for immediate and sweeping action, there is much to celebrate in the
report.



Under the auspices of the U.S. Global Change Research Program, an interagency
task force of long standing which is based just a short distance from the White
House, the climate change report essentially states that we are very far past
the tipping point on the subject of sea level rise. That most certainly is true
and the release of the climate change report constitutes a very significant
milestone in the fight against global warming.



The authors of the report, whose tenure extends back through multiple
presidential administrations of both political parties, have taken it upon
themselves to brief various colleagues in the federal government, including the
United States Congress, in the hope of driving reforms. Moreover, many of those
same authors are members of the United Nations Intergovernmental Panel on
Climate Change, which won the

Nobel Peace Prize with former Vice President Al Gore in 2007
.



On the whole, then, I am comfortable with the tenor of the report given the
enormous (but otherwise denied) political pressure which was applied to every
single author of the report in an attempt to dilute the language as much as
possible. If you would like to read the report and/or watch the video of the
press conference at which it was released, just visit



globalchange.gov



No matter how one feels about the report, however, one is left with a startling
question. The report points to ambassador species, flora and fauna being harmed
right now, at this moment, by climate change. What is to be done about them?



Well, if you have read my blog for any period of time, you know that I advocate
a low-carbon lifestyle, just as I have lived since 2005. For details, please
refer to the
carbon section
. However, one’s motivation to move to a low-carbon lifestyle
may fall short simply by reading the climate change report.





Hence, I advocate a more personal approach. I recommend examining the ambassador
species and determining how their loss impacts each of us. The good people at
Environmental Defense have created a handy section of their website to
facilitate doing just that. Called Warming and Wildlife, this page makes it easy
to read and help imperiled species including the puffin, the pika, the sugar
maple, the lynx, the monarch butterfly, the leatherback turtle and, of course,
the polar bear.



I exhort you to visit the page today. Review the information. Learn about how
these lovely ambassador species are being harmed right now, at this moment, by
climate change. Then, take action which the Environmental Defense website
enables you to do quite easily. The direct URL is

Acidification of Arctic Ocean Points toward Horrific Collapse of Sea Life Worldwide

Noted professor Jean-Pierre Gattuso of France’s National Center for Scientific Research (CNRS) is a leading authority on ocean acidification. Part of the broad EPOCA initiative (European Project on Ocean Acidification), Professor Gattuso and his esteemed team have been hard at work in the Arctic for more than a year providing fresh empirical evidence regarding the short-term, mid-term and long-term effects of this insidious problem.

As it turns out, Professor Gattuso’s findings are far worse than most experts had predicted for this point in humanity’s technological evolution and reliance on fossil fuels. First, a brief review.

Last year, I explained the dangers of ocean acidification and compared it to battery corrosion. In short, as we burn more and more fossil fuels, we are acidifying our oceans. We are changing the Ph of the sea water. The effect is not unlike the effect on the lungs of people who live downwind of chemical plants or petroleum refineries. Now, as it turns out, the news is even worse.

Professor Gattuso has pointed to a global collapse in sea life within a few short decades and the complete loss of sea life in the Arctic by the year 2018. This is no exaggeration and Professor Gattuso has the proof to back his statements. Gattuso concludes that, “The water will become so acidic it will actually dissolve the shells of living shellfish. This will affect the whole food chain, including the North Atlantic salmon, which feeds on mollusks.”

It’s terrifying, I know, but I suspect that you wonder why the Arctic is so close to biological implosion, right? Professor Gattuso explains that, too. “More carbon dioxide can dissolve in cold water than warm. Hence the problem of acidification is worse in the Arctic than in the tropics.”

So, what is to be done? Well, the solution to this cataclysm-in-the-making is the same as the solution to climate change: we must stop burning fossil fuels. To gather additional perspective, I recommend the following free 4-page Adobe document from the EPOCA blog:

http://epocaarctic2009.wordpress.com/the-science/the-experiments

In closing, I realize that the problem can seem abstract, especially since so few people live in the Arctic. So, I will close with this. The acidification of the Arctic is to the biological collapse of the oceans what the warming of the Arctic is to the warming of the climate. It is the canary in the coal mine, quite literally in this case.

I leave you with more from Professor Gattuso...

“10% of the Arctic Ocean will be corrosively acidic by 2018; 50% by 2050; and 100% ocean by 2100. Over the whole planet, there will be a threefold increase in the average acidity of the oceans, which is unprecedented during the past 20 million years. That level of acidification will cause immense damage to the ecosystem and the food chain, particularly in the Arctic.”

Polar Bear Week from Environmental Defense Reminds Us World's Largest Land Carnivore on Thin Ice

The imperiled fate of the polar bear, the world’s largest land carnivore, is easy to ignore because this majestic species lives in some of the most remote territory and enjoys natural camouflage, until now. The wintry splendor which used to surround the polar bear during every month of the year is melting at unheard of rates and killing off nearly all but the strongest specimens in the process.

Despite all of this needless, and often dismissed, devastation, no one with the political power to do anything about it seems to be acting. For this and several other reasons, a fine organization which I greatly admire, Environmental Defense, recently published a 6-part blog post which focuses a reader’s attention with laser-like precision on the plight of the polar bear and how this majestic species is suffering right now, today, because of global warming.

I exhort you to read it immediately at

edf.org/polarbearweek

Why should anyone but Eskimos care about this modern tragedy? Beyond the moral rectitude of not knowingly or deliberately causing the extinction of another species, the plight of the polar bear is an omen of the fate of billions of people. Yes, that’s right, billions.

We in the industrialized world have lost sight of the fact that billions of people still derive sustenance from subsistence farming (and/or participate in basic agrarian economies). As the effects of global warming propagate from the Arctic toward the Equator, the natural systems which make farming possible will shift and millions of acres of agrarian lands no longer will be arable.

In short, the suffering of the polar bear as admirably described in the 6-part blog post from Environmental Defense can be proved scientifically as a description of the food poverty and starvation which await billions of people in the coming years and decades. So, if you haven’t checked out that URL quite yet, why not visit it now?
