Post Carbon: Senators will unveil climate bill April 26

2010-4-28 · CO2 will soon be blamed for the earthquakes also. The polar ice was sort of squeezing the earth from both ends, and as 4% of the well under ten percent of the world''s ice loed at the north pole melted, all the crust was surely distorted. This might have led to tectonic plate movements which might have contributed to the deadly earthquakes.
