A new study published in the journal Nature , the global average temperature increase of 4 ° C for at least by 2100 years and Carbon dioxide emissions,will not reduced a maximum of 8 ° C potentially by 2200.

A news release from the University of New South Wales , according to the scientists not to scale back emissions of carbon dioxide by 2100 , the global average temperature will increase by at least 4 degrees Celsius estimate.
The findings appear in a recent article in the journal Nature and climate sensitivity may explain one of the great unknowns : the role of cloud formation and global climate change have an impact on whether it is positive or negative .
