Seven Things You Should Know About the IPCC 1.5°C Special Report and its Policy Implications

, Policy Director and Lead Economist, Climate & Energy

The Intergovernmental Panel on Climate Change (IPCC) is soon going to release an important report to help inform global efforts to limit climate change. The special report details the impacts of a global average temperature increase of 1.5°C relative to 2°C above pre-industrial levels, and pathways to limit temperature increase to that level. Governments of the world have come together this week in Incheon, South Korea to negotiate and agree on the report’s Summary for Policymakers, which is based on the underlying science in the final IPCC report. The summary is expected to be released on Monday morning in South Korea (late on Sunday night here on the US east coast).
