Is natural gas really the lesser of two evils?
FRISCO — As frackers desperately try to pump every last bit of gas from the ground before the global warming clock runs out, scientists warn that methane emissions could push Earth over a climate tipping point in just a few years.
“We have to control methane immediately, and natural gas is the largest methane pollution source in the United States,” said Robert Howarth, greenhouse gas expert and ecology and environmental biology professor at Cornell University. “If we hit a climate-system tipping point because of methane, our carbon dioxide problem is immaterial. We have to get a handle on methane, or increasingly risk global catastrophe.”
