France’s president Emmanuel Macron had an answer to President Donald Trump’s decision to tug America out of the Paris Agreement: invite scientists to research climate change solutions in his country instead. The Make Our Planet Great Again initiative now has its first class: 18 scientists from around the world. They’ll move from institutions like Princeton University, Stanford University, and the National Oceanic and Atmospheric Administration to work in France. Macron announced the 18 grants with French research minister Frédérique Vidal right before the One Planet Summit, a meeting convened by Macron, World Bank president Jim Yong Kim, and United Nations Secretary-General Antonio Guterres to work towards climate action.
