What’s New in the UN’s Special Report on 1.5C Warming?
The recent report from the United Nations’ Intergovernmental Panel on Climate Change (IPCC) shows that human activities have already caused 1.0C global warming, but that past emissions alone do not cause a warming of 1.5C. This report addresses the emission reductions required to keep warming below 1.5C, what the climate impacts would be of achieving 1.5 vs. 2C and what these imply for adaptation requirements. An important part of the report is evaluating the synergies and tradeoffs between climate mitigation, adaptation, eradication of poverty and sustainable development. Ambitious and unprecedented changes in behavior and transitions across many sectors, including energy and agriculture, are required, in addition to the research, development and deployment of carbon dioxide removal technologies.
