What IPCC 1.5 Degree Report Means for Global Climate Action

IPCC lead climate author Oliver Geden talks about how politicians view the IPCC's 1.5 degree report, and implications for climate action.

On October 8th the Intergovernmental Panel on Climate Change released its report on Global Warming of 1.5 degrees. The report describes expected environmental, economic and social impacts brought by 1.5 degrees Celsius of climate warming, and the actions that need to be taken on a global scale to limit warming to that level.

The report’s timing is crucial, as it comes ahead of this December’s global climate meeting in Katowice, Poland, where nations that signed onto the Paris Climate Accord will establish the rules that will guide them in reaching their climate commitments. The IPCC’s report serves as a guide to how much countries might be able to limiting warming. Yet at the same time, the report highlights the unprecedented effort that would be required to hold to the 1.5 degree target.

Oliver Geden, a lead author of the IPCC’s next major report on climate change, discusses the implications of the IPCC report for policymakers and for the upcoming UN Climate Summit.
