UN adopts new landmark climate change report

The United Nations' expert panel on climate science has finally adopted a report on global warming after all-night talks that will be later issued to public.

The landmark report, which combines the findings of three earlier reports, offers "conclusive evidence" that a human are altering the Earth's climate system and has been adopted by the Intergovernmental Panel on Climate Change.

Apart from discussing the human influence, it is expected to describe how climate impacts, including melting Arctic sea ice and rising levels, are already happening and could become irreversible unless the world curbs its greenhouse gas emissions.

The IPCC says scientists are now 95 percent certain that the build-up of such gases from the burning of fossil fuels and deforestation is the main cause of warming seen since the middle of the 20th century.
