The United Nations’ Intergovernmental Panel on Climate Change says that the earth’s temperature will rise by 1.5 degrees Celsius by 2040 if we don’t curb our greenhouse gas emissions.

Dr. Alan Robock, Distinguished Professor of climate science in the Department of Environmental Sciences at Rutgers University, joined us to explain the research, the technology, and the unintended consequences.
