CLIMATE CHANGE

Last night I caught a bit of a very short documentary film on the PBS Frontline series about how global warming is impacting various remote areas of the world. The part I caught was about the Himalayas. The most stunning evidence was a photo taken recently of a view of a giant glacier beneath Mount Everest and comparing it with one taken by Hilary I think they said in the 1920s (though didn't he successfuly climb it in the '50s?, which would make the changes even more rapid).

The diminishment of the glacier is so striking (at least 50 percent loss) not only because of the amount of ice that has disappeared and will have terrible consequences for water flow as far away as the Yangtse River in China, but for my aesthetic taste, the devastation to the beauty of the area. The difference between miles of white and blue-white glaciers like a river of snow and a landscape of exposed brown and gray rock benetah it is the loss of a natural work of art.

Though some kind of "beauty" can be found in almost everything, if not everything, I prefer the snow capped mountains and glaciers to the now bare and barren rock outcroppings and dry riverbeds.

There was another documentary on a cable channel I think may have been IFC (or maybe it was Sundance) also on global warming and the impact of manmade causes contributing to it, and all this was preceded by an e mail from my old friend Mike Graham from California with the following AP wire story, which I reproduce here in full:

NASA warming scientist: 'This is the last chance'
By SETH BORENSTEIN, AP Science Writer

June 23, 2008

Exactly 20 years after warning America about global warming, a top NASA scientist said the situation has gotten so bad that the world's only hope is drastic action.

James Hansen told Congress on Monday that the world has long passed the "dangerous level" for greenhouse gases in the atmosphere and needs to get back to 1988 levels. He said Earth's atmosphere can only stay this loaded with man-made carbon dioxide for a couple more decades without changes such as mass extinction, ecosystem collapse and dramatic sea level rises.

"We're toast if we don't get on a very different path," Hansen, director of the Goddard Institute of Space Sciences who is sometimes called the godfather of global warming science, told The Associated Press. "This is the last chance."

Hansen brought global warming home to the public in June 1988 during a Washington heat wave, telling a Senate hearing that global warming was already here. To mark the anniversary, he testified before the House Select Committee on Energy Independence and Global Warming where he was called a prophet, and addressed a luncheon at the National Press Club where he was called a hero by former Sen. Tim Wirth, D-Colo., who headed the 1988 hearing.

To cut emissions, Hansen said coal-fired power plants that don't capture carbon dioxide emissions shouldn't be used in the United States after 2025, and should be eliminated in the rest of the world by 2030. That carbon capture technology is still being developed and not yet cost efficient for power plants.

Burning fossil fuels like coal is the chief cause of man-made greenhouse gases. Hansen said the Earth's atmosphere has got to get back to a level of 350 parts of carbon dioxide per million. Last month, it was 10 percent higher: 386.7 parts per million.

Hansen said he'll testify on behalf of British protesters against new coal-fired power plants. Protesters have chained themselves to gates and equipment at sites of several proposed coal plants in England.

"The thing that I think is most important is to block coal-fired power plants," Hansen told the luncheon. "I'm not yet at the point of chaining myself but we somehow have to draw attention to this."

Frank Maisano, a spokesman for many U.S. utilities, including those trying to build new coal plants, said while Hansen has shown foresight as a scientist, his "stop them all approach is very simplistic" and shows that he is beyond his level of expertise.

The year of Hansen's original testimony was the world's hottest year on record. Since then, 14 years have been hotter, according to the National Oceanic and Atmospheric Administration.

Two decades later, Hansen spent his time on the question of whether it's too late to do anything about it. His answer: There's still time to stop the worst, but not much time.

"We see a tipping point occurring right before our eyes," Hansen told the AP before the luncheon. "The Arctic is the first tipping point and it's occurring exactly the way we said it would."

Hansen, echoing work by other scientists, said that in five to 10 years, the Arctic will be free of sea ice in the summer.

Longtime global warming skeptic Sen. James Inhofe, R-Okla., citing a recent poll, said in a statement, "Hansen, (former Vice President) Gore and the media have been trumpeting man-made climate doom since the 1980s. But Americans are not buying it."

But Rep. Ed Markey, D-Mass., committee chairman, said, "Dr. Hansen was right. Twenty years later, we recognize him as a climate prophet."

[PS: Just after I posted this, the federal agency that puts together all the intelligence agencies reports just issued a concensus report on the impact global warming will have on USA security over the next thirty years, saying global warming and rising sea levels is already a fact and will play a major role in population displacement and conflicts over resources, etc.]

great post michael - the godfather lives down the road from my studio out here in rural upper bucks - the changes are dramatically recognizable every year - especially with that fickle delaware river, drainage, development, erosion, etc. - and as hansen usually puts it - 'we're past the tipping point' ...
i'm not surprised that the powers that be don't recognize his expertise with more seriousness ...
like artists, his job is to observe and report ...
a fairly passive approach to an agressive problem and the ensuing stonewalling for profit ...
as far as 'the americans aren't buying it' comment - what a scapegoat remark - i think most americans are simply slaves to a system that requires some major legistlation reform that politicians sacrifice for lobby money ...
we're blessed with challenges i guess ...

Ah, just tonight I was discussing with Peg Stone the erratic weather patterns we've been experiencing here in the NY-Metro area and how nobody (meaning the media, it's not front page news) is talking about it....should have known to check your blog. Are only poets paying attention?

Does anyone else find the almost daily thunderstorms, accompanied by hail, the numerous "micro-bursts" reported in Jersey, New York and CT, that come quickly, destroy trees and property and kill power, odd?

I'm 42, do I qualify to have lived long enough to say 'there's something very different and strange about the weather?'

And I'm angry, because the go-green, stop global warming, reduce-your-carbon-footprint campaigns are admirable and necessary for us as individuals, and we should all care about our contribution to the problem BUT isn't it also wrong to put the responsibility solely on us, as consumers?

Do we do that, take it all on ourselves, and let the multi-billion dollar corporations that created the pollution-spewing, gas-guzzling, environment and resource destroying consumer products WITH THE FULL KNOWLEDGE OF THE DAMAGE THEY WERE DOING off the hook?

Or absolve the current administration of its part in this catastrophe? An administration that set the US (and the world) back DECADES with its' de-regulation of industry, overturning of environmental laws and aggressive push for drilling on soils domestic and foreign?

Are the CEO's, CFO's, etc. of all the oil companies of the world secretly building cities on other planets, and rocket-ships, to send their children and grandchildren to live on when this planet becomes uninhabitable due to their unchecked greed?

go kid - leave it to a poet to acupressure the issues ...
been thinking about this word 'terror', tactics of deception, and how the american public - if not the vast majority of the world's population, is being held hostage or losing life as a result of poverty, war, and famine related to the policies of government and big business - under some presumption that we either 'can't handle the truth' or we're too stupid to understand it - so while the left hand is enabling a few dozen outlaws to engage in activities that cause the deaths of a few thousand, the right hand is implementing policies that accept the deaths of hundreds of thousands as acceptable casualties of a war on terror that in itself is such an ambiguous pursuit it defies clear targets - where what it really has become is a 'war on opposition' - and the first to define it are guilty of atrocities comparable to those of their enemies ...
when are the people going to stand up to the real bullies, or are the laws they created to insulate themselves so impenetrable there is no hope for justice or a true form of democracy - let alone a sustainable planet ...
