Dear Governor Greenwash

Hansen: Governors aren’t getting it

My recent experience with governors raises a question about whether this is an effective way to communicate about climate change. (Apologies for the length -- you may skip the three tales and go to the bottom line.) Dear Governor Pawlenty [PDF] Minnesota Gov. Pawlenty presides over a population that appreciates nature. Explorer Will Steger has done a marvelous job of informing the public there about climate change in the Arctic, the threat of climate change to species and indigenous people, and the relevance of climate change to Minnesota. Early actions made it appear that Minnesota would be a leader, defining energy policies and directions that would be a great example for other states. Specifically (get this!), in spring 2007 Minnesota passed and Gov. Pawlenty signed a law called the Next Generation Energy Act of 2007, requiring 25 percent renewable energy by 2025 and a 1.5 percent per year improvement in energy efficiency. Some people used this to help paint Gov. Pawlenty green, second in greenness only to Arnold Schwarzenegger among Republican governors. Pawlenty, according to the Washington Post, is at the top of the list of candidates to be John McCain's running mate. Coincidentally, the Republican convention will be in Minnesota in September.

Forests and fires foster fearsome feedbacks

Previously, I looked at why the permafrost won't be perma for long. Then I looked at whether the potential destruction of the tundra represents the point of no return for the climate, necessitating that we keep atmospheric concentrations of carbon dioxide below 450 ppm or else risk going to 800 ppm to 1,000 ppm. Here I examine two local amplifying feedbacks that further threaten the permafrost: forests and fires. Reduced snow cover and albedo (reflectivity) in the summertime Arctic landscape, caused by global warming, has added local atmospheric heating ($ub. req'd) "similar in magnitude to the regional heating expected over multiple decades from a doubling of atmospheric CO2." That same Science study warns "Continuation of current trends in shrub and tree expansion could further amplify this atmospheric heating 2-7 times."
