Climate pledges by 140 countries will limit global warming – but not enough

Analysis of nations' carbon emissions pledges ahead of Paris climate summit shows they would see 2.7C warming by 2100, breaching 2C 'safety' threshold

Plans submitted by 140 nations to limit their greenhouse gases would go some way towards tackling climate change, but not enough to prevent the planet from warming by well over 2C compared to pre-industrial times, experts say.

The plans by countries from Albania to Zimbabwe, led by top emitters China and the United States, were submitted by an informal United Nations deadline on Thursday as building blocks towards a climate accord that negotiators will try to clinch at a summit in Paris in December.
