Is There Reason for Optimism on Climate Change?

The science is as conclusive as science gets. Anthropogenic climate change is happening, and as a recent paper in Science noted, “without major reductions in greenhouse gas emissions to the atmosphere, terrestrial ecosystems worldwide are at risk of major transformation.” The authors told the Washington Post, “What we’re talking about here are the kinds of changes that disrupt everybody’s lives.”

Despite the consensus among scientists, the Trump administration intends to withdraw from the Paris climate accord—something it can’t actually do until the day after election day in 2020.
