Challengers in climate change lawsuits are failing to use the latest science on global warming to bolster their legal claims, a new study has found. The research published yesterday in the journal Nature Climate Change shows how scientific studies could support climate litigation against companies and governments in courtrooms around the world. The paper focused on attribution science, a burgeoning field of research that examines whether—and how much—climate change contributes to extreme weather events. In addition, 26 lawsuits asserted that climate change had caused extreme weather events without providing any evidence to back up this claim. “Climate attribution science has long been called suspect even by supporters of climate litigation,” Allison said.
