As in the case of chemical plants or landfills, often there isn't definitive evidence that climate change is a primary reason for displaced people / refugees to leave their homes. Podesta at the Brookings Institution (2019) discusses how changed weather patterns, storms, and fires are displacing people already, and these events seem to be exacerbated by climate change. He says, "Multilateral institutions, development agencies, and international law must do far more to thoroughly examine the challenges of climate change." Can it be agreed?
