Robert Howarth is Professor of Ecology & Environmental Biology at Cornell University. He is an expert on natural gas & methane and their impact on the climate. In this wide-ranging interview, Prof. Howarth discusses how methane’s powerful warming capability (87X more effective than CO2 in warming the world over a 20-year period) and its high leakage rate from the extraction, transportation, and utilization processes makes it about as bad as coal when it comes to short-terms global warming.
