George Bush Sr. must've been right when he said the "American way of life is non-negotiable." That'd explain why US scientists are pushing bizarre technologies such as "giant mirrors in space or reflective dust pumped into the atmosphere" as a last-ditch attempt to cut carbon emissions rather than, you know, signing a global-warming treaty. In fact, after a new report by the Intergovernmental Panel on Climate Change said global warming is “unequivocal” and that human activity has "very likely" caused most of the temperature increases since 1950, 45 nations signed a pact agreeing to reduce greenhouse gases. The US—producer of about 25% of global warming emissions—did not sign, nor did China or India.
One factor in the US lagging behind the rest of the world in accepting and addressing this problem:
Only 13 percent of Congressional Republicans believe global warming is man-made, according to a National Journal poll. Among Democrats, 94% believe humans exacerbate our climate problems.
