SYDNEY - The world needs to redouble efforts to fight climate change ahead of global talks in Durban, with time running out to save millions of lives in countries to be hit hardest, United Nations Secretary-General Ban Ki-moon said on Thursday.
Ban, winding up a visit to Australia and small Pacific nations including several likely to be swamped by rising sea levels, said critics of climate change science were wrong.
"The facts are clear. Global greenhouse gas emissions continue to rise. Millions of people are suffering today from climate impacts. Climate change is very real," Ban said in a speech at Sydney University.
"Environmental migrants are starting to reshape the human geography of the planet. This will only increase as sea-levels rise and deserts advance. We cannot burn our way to the future," he said.
