Climate Change is Happening Faster Than Expected

I have repeated this warning like a mantra for several years. There are several factors with the predictions and modeling for climate change that will lead to the change being more rapid than projected. The factors are complex and varied, I can spell some of them out, but the bottom line is that we have less time than we think to fix the problem. The cost of the fix increases every day we delay. The impact is being felt. People around the world already know it is happening. The 5 to 7 degree range by 2100 is a slow moving disaster and it is probably the best we can hope for.

Faster Climate Change Feared

New Report Points to Accelerated Melting, Longer Drought

The United States faces the possibility of much more rapid climate change by the end of the century than previous studies have suggested, according to a new report led by the U.S. Geological Survey.

Ice sheets in the Antarctic and Greenland, above, are losing 48 cubic miles per year, pushing up sea level worldwide.


The survey — which was commissioned by the U.S. Climate Change Science Program and issued this month — expands on the 2007 findings of the United Nations Intergovernment Panel on Climate Change. Looking at factors such as rapid sea ice loss in the Arctic and prolonged drought in the Southwest, the new assessment suggests that earlier projections may have underestimated the climatic shifts that could take place by 2100.
