UN: 3C of warming under current global climate pledges

The United Nations Environment Programme (Unep) said that pledges put forward to cut emissions would see temperatures rise by 3C above pre-industrial levels, far above the the 2C of the Paris climate agreement, which comes into force on Friday.

At least a quarter must be cut from emissions by the end of the next decade, compared with current trends, the UN said.

The report found that emissions by 2030 were likely to reach about 54 to 56 gigatonnes of carbon dioxide equivalent a year, a long way astray of the 42 gigatonnes a year likely to be the level at which warming exceeds 2C.
