The United Nations Framework Convention on Climate Change (UNFCCC) has completed its analysis of country pledges on climate mitigation, or Intended Nationally Determined Contributions (INDCs), in advance of the COP21 Paris climate conference, and found that, combined, they could result in a world average 2.7°C of warming on 1990 levels. Such a level of warming is above the accepted 2°C target, but is a marked improvement from the 4-6°C possible outcome if emissions rose unchecked, reports Marc Height.
