Global Warming Is 'Not Science Fiction'The climate change threat is "not science fiction" and reversing it is the "defining challenge of our age", the UN chief has warned.
Climate change has already begunBan Ki-moon said the potential impact of global warming is "so severe and so sweeping that only urgent, global action will do".
He was speaking in Valencia, Spain, to the Intergovernmental Panel on Climate Change, which has issued its latest report after six years of research.
It says the Earth is heading towards a warmer age at a faster pace and warned of inevitable human suffering and the threat of species extinction.
It believes climate systems have already begun to change, with warming of air and ocean temperatures, widespread melting snow and ice, and rising sea levels.
The UN Secretary-General has visited some of the areas worse affected so far by climate change.
Mr Ban said in the Amazon "the rain forest, the lungs of the Earth, is being suffocated".
He added: "In Chile the sight of one of the holes in the atmosphere, children wear protective clothing against ultraviolet radiation radiation."
Action needed to save planetHe said some days the children are not allowed to play outside or go to school.
"These scenes are frightening like science fiction movies," he explained.
"But they are even more terrifying because they are real and reversing these threats is the defining challenge of our age."
He also said poorer nations will be hit hardest because melting glaciers will trigger floods and lead to water shortages in South-East Asia and America.
The report will now be used as a how-to guide for policy makers meeting next month in Bali, Indonesia.
They will begin discussing a successor agreement to the Kyoto Protocol, which requires 36 industrial countries to reduce carbon emissions by an average 5% from 1990 levels by 2012.
