Mongabay: COP26 – As carbon emissions rise unabated, scientists eye a methane removal fix

One of the leading causes of methane emissions is flaring like this done at facilities drilling for natural gas.

I arrived in Glasgow, Scotland, for my seventh United Nations climate summit on Friday, November 5, my birthday. I celebrated by self-administering a Covid-19 test in my AirBnB apartment, reporting the negative result to the National Scottish Health Service, then hailing a taxi to the venue. There, after weaving my way through unusually mobbed corridors of masked people from around the world, I met up, as planned, with Daphne Wysham, chief executive of Methane Action, for this story, which posted the following Monday.

Over the course of a half day that Friday and most of Saturday, I climbed the learning curve regarding methane as a greenhouse gas, how much more potent in its heat-trapping capacity it is than carbon dioxide, and why it only lasts in the atmosphere for 10-12 years, compared to centuries for CO2. Those details alone make methane a ripe target for climate action. In fact, more than 100 nations signed a declaration before I arrived in Scotland to reduce their own methane emissions by 30 percent by 2030. It’s far from enough, which is where Methane Action comes in.

Daphne was eager to talk not only because she has a remarkable story to tell, but also because she and I met in Port Townsend, Washington, last July when I was reporting on the value of old-growth trees in temperate rainforests while in Washington state. Her husband John Talbert, a forest ecologist, was one of my sources. I learned just enough about Daphne’s work to know I wanted to follow up.

This is one of the more surprising stories I’ve reported and written at a climate summit. It’s actually hopeful, I realized, as I slowly grasped how engineered methods of methane oxidation — if proven in the lab and then successfully applied at a global scale — could turn out to be the most effective way of slowing global warming in the short term. It also holds the hard-to-believe potential of actually bringing about global cooling in a few decades. My story provides the details, with all the necessary caveats.

WUNC The State of Things: Conference Critical For Implementing Climate Change Plans

COP 22, UN Climate Summit, Marrakesh, Morocco

COP 22, UN Climate Summit, Marrakesh, Morocco

I arrive on Nov. 11, 2016 to cover my third consecutive UN Climate Summit, COP22, this one in Marrakesh, Morocco. Today, Nov. 8, 2016 — Election Day in the U.S. — I was interviewed on WUNC’s The State of Things of the significance of this summit and what’s at stake. The recording of my conversation with host Frank Stasio is here. Thanks to Anita Rao for her excellent preparation and production.
