Dr. James Hansen calls for moratorium on coal and phasing out by 2020
Dr. Hansen stated that we have already exceeded a safe amount of CO2 in the atmosphere, which he places at 350 parts per million (ppm). He testified that the US must begin using a carbon tax to lower the nation’s emissions and that the US must stop producing energy from coal by 2020.
James Hansen heads the NASA Goddard Institute for Space Studies in New York City. He is currently an adjunct professor in the Department of Earth and Environmental Sciences at Columbia University and serves as Al Gore’s science adviser. Hansen is best known for his research in the field of climatology and his testimony on climate change to congressional committees in the 1980s that helped raise broad awareness of the global warming issue.
