Satellites Can Now Identify Methane ‘Super-Emitters’

In 2024, two new satellites were launched to find methane super-emitters from space: the Environmental Defense Fund’s MethaneSAT took off in March 2024; and Carbon Mapperlaunched later last year as a public-private partnership. Methane is a super-powered greenhouse gas. Pound-for-pound, methane is 80 times more potent than carbon dioxide in the first two decades after […]

Airborne observations identify major source of US landfill methane emissions

Example images of a landfill with methane emissions from the work face. Credit: Environmental Science & Technology (2024). DOI: 10.1021/acs.est.4c07572 A team has found via testing from airplanes that landfill work faces tend to be responsible for the biggest share of methane emissions in U.S. landfills. Their findings are published in the journal Environmental Science […]

Saturn’s moon Titan may have a 6-mile-thick crust of methane ice — could life be under there?

Scientists have discovered that the icy shell of Saturn’s largest moon, Titan, could possess an insulated, six-mile-thick (9.7-kilometer-thick) layer of methane ice beneath its surface. Ironically, this layer may make signs of life from the subsurface ocean of Titan easier to detect. And, down the line, the discovery could benefit the fight against human-driven climate […]
