Sir David King Urges Global Pact by 2009 to Reduce Greenhouse Gases

摘要

Wealthy and developing nations should join to approve a global pact by 2009 to sharply reduce greenhouse gas emissions and avoid "catastrophic" climate change, Sir David King, the U.K.'s chief scientific adviser, said in a lecture at AAAS on 13 July. Speaking to an overflow audience, King said that the Earth is already feeling destructive effects of human-caused climate change. But if a rigorous new agreement could be approved in 2 years and implemented by 2012, he said, atmospheric concentrations of greenhouse gases could be stabilized between 450 and 550 parts per million.
