Many scientists concede that without drastic emissions reductions by 2020, we are on the path
toward a 4C rise as early as mid-century, with catastrophic consequences, including the loss of the world's coral reefs; the disappearance of major mountain glaciers; the
total loss of the Arctic summer sea - ice, most of the Greenland ice - sheet and the break - up of West Antarctica; acidification and overheating of the oceans; the
collapse of the Amazon rainforest; and the loss of Arctic permafrost; to name just a few.
