For years, governments, industry, and TV ads told us natural gas is the safe bridge fuel while we move away from dirty coal and oil.
Cornell University scientist Robert Howarth wondered "Is that true?". When Howarth found no science to back up big claims for the gas industry, he and a team from Cornell went to work.
Program includes 27 minute speech by Professor Robert Howarth of Cornell at ASPO USA 2011, November 2nd in Washington D.C. Recorded by Carl Etnier of Equal Time Radio, Vermont. My thanks to ASPO USA for this fine presentation.
Then a follow-up interview this week with Robert Howarth, to fill in his hurried climax of the speech - that methane emissions, when calculated over 20 years, using the new higher rate discovered by Drew Shindell - could add up to at least 44% of all greenhouse gas emissions in the United States! We discuss this, and the importance of a 2006 paper by Dr. James Hansen of NASA, on the importance of controlling methane emissions.
