Climate Change, 2007

摘要

On February 2, 2007, the Intergovernmental Panel on Climate Change (IPCC) released a 21-page report, updating the one previously released in 2001. This report represents the consensus views of 2,500 top scientists and policy makers concerned with all aspects of global warming. These people derive from 130 nations, representing many diverse views, values and concerns. Yet they are unified by the overwhelming evidence concerning climate change. The report blames humans for the global wanning "runaway train," and this conclusion has now been stated with much greater certainty than ever before. Officials in the United Nations and elsewhere have issued statements to the effect that: "The debate about global warming and its causes is now over. It's time to act."
