As countries across the world gear up for the 2015 climate conference in Paris, the Intergovernmental Panel on Climate Change (IPCC) on Sunday unveiled a report warning governments of the “unequivocal” warming of climate system and the “clear” evidence of human influence on the phenomenon.
The IPCC released its last of the four reports, called the Synthesis Report, in Copenhagen Sunday.
This last part of the Fifth Assessment Report has been widely described as the most comprehensive assessment of climate change ever made.
The report comes weeks before the annual climate conference begins in Lima, Peru.
The conference is expected to prepare the ground for countries to stitch together a comprehensive climate agreement at the meeting in Paris next year.
“The evidence produced this time is the strongest. There is absolutely no room for doubt now. The IPCC is telling all the governments to act now and act forcefully,” said Purnamita Dasgupta of Delhi-based Institute of Economic Growth who is part of the team that wrote the report.
R K Pachauri, the head of the IPCC said: “We have little time before the window of opportunity to stay within 2 degree of warming (which scientists say is necessary to prevent catastrophic effects) closes. To maintain a good chance of staying below 2 degrees, and at manageable costs, our (greenhouse gas) emissions should drop by 40 to 70 per cent globally between 2010 and 2050, falling to zero or below by 2100. We have that opportunity, and the choice in our hands,”
