Paris Agreement Won’t Stop Us Breaking Crucial Global Warming Limit, Warns UN

The planet is set to pass the crucial 2C global warming limit, even if pledges outlined in the Paris Agreement are implemented, the UN has warned.

A report from the UN’s Environment Programme says efforts to cut emissions must go beyond the official commitments, which come into force today. 

Without swift emission reductions, the report said the world is on track for a temperature rise of 2.9C to 3.4C this century.

Significantly, that projection is based on governments sticking to the pledges agreed in Paris last year.

The Paris Agreement committed signatories – including the UK – to holding the increase in global average temperatures well below 2C above pre-industrial levels and to pursue efforts to limit it to 1.5C, which it said would “significantly reduce the risks and impacts of climate change”.

But the Unep report finds that, on current trends, emissions are set to reach the equivalent of 54-56 gigatonnes (billion tonnes) of carbon dioxide by the end of the next decade – well above the 42 gigatonne maximum if warming is to be kept below 2C.

The demand for urgent action is reinforced by the fact that 2015 was the hottest year on record and the first six months of 2016 were each the warmest recorded, said the report.
