Only 38 Years Until 3C Global Warming?

While we usually think of severe climate change being something that people under age 20 might have to deal with much later in their lives, the findings of a new study suggest that even people now in their 40s or 50s may have to deal with the extreme weather of a world warmed up by 3C. Those planning to retire in the south or southwest perhaps should perhaps reconsider. Maine might be a wiser choice.

The study was the biggest climate computer simulation study ever carried out. It included 10,000 simulations which were run on home computers. The large number of simulations increased the accuracy of the study. The 3C increase is 0.8C higher than the maximum temperature increase of 2.2C by 2050 projected by the Intergovernmental Panel on Climate Change (IPCC). Scientists are extremely concerned about reaching 2C. At the recent Planet Under Pressure conference in London, Will Steffen, executive director of the Australian National University's climate change institute, called for radical action to combat climate change. He said "We can...cap temperature rise at two degrees, or cross the threshold beyond which the system shifts to a much hotter state.” He also noted "Under a worst-case scenario, it's very likely, I think, that the Earth's system will move to a new state of some sort, with a very severe challenge to contemporary civilization…Some people have even talked about a collapse."

All of this seems lost on our politicians representing us in Washington. The gap between science and politics could hardly be any wider. President Obama sounded like he was going to try to close it when he campaigned for office in 2008 but now four years later we are still waiting for him to act on his words.
