In The Hill: Focus on methane is timely and appropriate

Smoke and steam billowing from and oil refinery smoke stack.

Policymakers have gotten the memo about methane’s outsized role in climate change, and thankfully, they’re swinging into action to reduce methane pollution, including a new U.S.-EU pledge to cut methane emissions 30 percent. But since the promised cuts can’t cover all methane sources, there is uncertainty about how far and how fast they will lower atmospheric methane […]

Methane removal and the proportional reductions in surface temperature and ozone

Red and purple clouds against a star-filled early evening sky.

Abstract Mitigating climate change requires a diverse portfolio of technologies and approaches, including negative emissions or removal of greenhouse gases. Previous literature focuses primarily on carbon dioxide removal, but methane removal may be an important complement to future efforts. Methane removal has at least two key benefits: reducing temperature more rapidly than carbon dioxide removal […]

Atmospheric methane removal: a research agenda

Abstract Atmospheric methane removal (e.g. in situ methane oxidation to carbon dioxide) may be needed to offset continued methane release and limit the global warming contribution of this potent greenhouse gas. Because mitigating most anthropogenic emissions of methane is uncertain this century, and sudden methane releases from the Arctic or elsewhere cannot be excluded, technologies for methane […]

Are We Finally Ready to Tackle the Other Greenhouse Gas?

Methane Action’s work is featured in The New Yorker’s Climate Crisis Newsletter by Bill McKibben. Here’s an excerpt : “Given both the threat and the opportunity, some scientists have begun wondering whether there might be ways to scrub some methane from the atmosphere. As with carbon dioxide, you can remove CH4 with “direct air capture,” which […]

Washington Post LTE: Negative Emissions

A mercury thermometer with a blazing sun in the background.

[The following is a letter to the editor written by Methane Action board member Peter Jenkins that appeared here in the Washington Post on July 7, 2021.] The July 1 editorial “Melting in the Pacific Northwest” was right to glimpse a dystopian future in the current heat wave. It’s true that greenhouse gases already emitted, also known […]

A nature-based negative emissions technology able to remove atmospheric methane and other greenhouse gases

Abstract Fulfilling the Paris Climate Agreement requires reducing rapidly the new emissions of greenhouse gases (GHGs) to reach net zero by 2050. As some anthropogenic emissions cannot be zero, to compensate them it will be necessary to remove GHGs from the atmosphere. Among possible methods, the Iron Salt Aerosol (ISA) offers new possibilities, including removal […]
