Cautionary words on climate from a May 1 statement by George Woodwell, the founder and Director Emeritus of The Woods Hole Research Center.
 I explore below paths that might, if followed, lead out of the chaos of an open-ended climatic disruption. Unfortunately the issues are complicated, the time for action is now late, and effective action is growing more difficult daily. Effective action is possible, however….
The changes in climate are far more serious than they may appear…. These changes, the warming of the higher latitudes, the destruction of forests, the accelerated decay of organic matter in forests and tundra soils, the melting of permafrost, the change from a reflective frozen white to black open water in the Arctic Ocean, and the warming of the surface water of the oceans all point to an acceleration of the warming trend. These are “positive feedbacks” which dominate as the earth warms and accelerate the disruption. Despite their importance, they have not been included in appraisals that suggest that a two degree average change in the temperature of the earth might be acceptable. The fact is that the feedbacks will almost certainly take the disruption beyond human control well before the temperature rise is two degrees C. Stopping at 2 degrees will not be possible. «Read the rest of this article»

On April 14, 2008, James Hansen of NASA Goddard Institute and Columbia University Earth Institute wrote the following letter to Governor Jim Gibbons (Nevada) as a “Plea for Leadership” in the battle against global warming, a battle to save Planet Earth. We thought this “plea,” this request for stewardship, was worth repeating. For the complete document (including “Fossil Fuel Facts” referenced within) and supportive documentation on this issue, please check out http://www.columbia.edu/~jeh1/mailings/20080414_GovernorGibbons.pdf
 Dear Governor Gibbons,
I hope that I may communicate with you as a fellow parent and grandparent about a matter that will have great effects upon the lives of our loved ones. I refer to climate change, specifically global warming in response to human-made carbon dioxide (CO2) and other pollutants.
Governor Gibbons, the scientific advances in just the past few years, paradoxically, carry both bad news and good news. We have already passed the threshold of atmospheric CO2 levels that we can allow to exist over the long-term. Mother Nature, as a friend of mine has noted, is wagging her finger at us, saying “Now you have gone too far!” Consequences of ignoring this admonishment would be dire. The Earth is nearing climate “tipping points” with potentially irreversible effects, including extermination of countless species, ice sheet disintegration and sea-level rise, and mass dislocation of populations. «Read the rest of this article»
