To solve climate, first achieve peace.

The horrific invasion of Ukraine by Russia has many devastating effects. The most immediate are on the people of Ukraine, but the long-term implications for the entire planet are enormous. For science, the disruption to international collaboration must be addressed and we must give our strongest support to Ukrainian scientists, as outlined by Marcia McNutt and John Hildebrand in a recent editorial. But for climate change, the effects may be the greatest. If we want a positive energy future for a healthier climate, the West must start by recasting foreign policy with climate and energy issues at the forefront. That can only succeed if nations strengthen the commitment to settle differences with diplomacy, not war. The only truly life-sustaining climate will be one accompanied by international peace.
