Have you heard about the miracle quick-fix for our climate ills?
The greenhouse gas methane is responsible for roughly 30 percent of the increase in global temperature since the industrial revolution and is often described as 80 times more potent than carbon dioxide. Sometimes news outlets remember to qualify that with “over 20 years,” and sometimes they don’t.
In a press call during the 28th Conference of Parties, the annual United Nations climate conference, US Sen. Sheldon Whitehouse of Rhode Island said methane was his “number one” priority at the conference. Shortly after, the Biden administration announced a new EPA rule targeting methane emissions. The press release announcing the rule stated, “Sharp cuts in methane emissions are among the most critical actions the United States can take in the short term to slow the rate of climate change.”
“[T]he U.S. is turbocharging the speed and scale of climate action, at home and abroad, including our collective efforts to tackle super-pollutants like methane,” said US National Climate Advisor Ali Zaidi.
The popular narrative suggests that tackling methane emissions is the “low-hanging fruit” in the climate-solutions toolbox. The belief that turning off the taps on this “super-pollutant” could “buy us time” to address the climate crisis is widespread, shared by politicians, journalists, and even some scientists.
But this is a dangerous fallacy, according to Raymond Pierrehumbert, a professor of physics at the University of Oxford and a member of the Bulletin of the Atomic Scientists Science and Security Board.
In an in-depth interview with Bulletin climate editor Jessica McKenzie, Pierrehumbert dissects the Oil and Gas Decarbonization Charter—the voluntary pledge made at COP28 by some oil and gas companies to slash operational emissions of greenhouse gases, including bringing methane emissions to “near-zero.” He goes on to explain why describing methane as “80 times as potent as carbon dioxide” is inaccurate and misleading and why the widespread hope that sharp cuts to methane emissions will bring about immediate and significant reductions of global temperatures is both wrong and distressing.
