The Intergovernmental Panel on Climate Change (IPCC) has published its Special Report on Global Warming of 1.5°C, a new assessment on minimizing global warming, and multiple IIASA researchers were involved in its production.
The 1972 Clean Water Act has driven significant improvements in U.S. water quality, according to the first comprehensive study of water pollution over the past several decades, by researchers at UC Berkeley and Iowa State University.
