The world faces a planetary emergency that requires considering all possible options to tackle it, said Johan Rockström, in a C2GTalk interview. Speaking just before the Climate Ambition Summit in December 2020, he said this was a critical moment to put the world on an irreversible path towards decarbonization, to ensure that any consideration of additional approaches—such as solar radiation modification—would not undermine that essential work. Johan Rockström is director of the Potsdam Institute for Climate Impact Research and Professor in Earth System Science at the University of Potsdam. Rockström is an internationally recognized scientist for his work on global sustainability issues. He spearheaded the internationally renowned team of scientists that developed the planetary boundaries framework, which are argued to be fundamental in maintaining a "safe operating space for humanity." Aside from his research helping to guide policy, he acts as an advisor to several governments and business networks, and at noteworthy international meetings, such as the United Nations General Assemblies, World Economic Forums, and the United Nations Framework Convention on Climate Change conferences (UNFCCC).
