Arctic Methane Plumes, NASA CARVE and 2030 Warming
The "clathrate gun" hypothesis involves the release of methane hydrates from the Arctic Ocean, a gas over 100 times more powerful than CO2 in the short term. NASA's CARVE project documented methane plumes 150 kilometers wide in 2013, indicating the process has accelerated since 2007. Analysis by Sam Karana suggests this feedback loop could lead to a 4-degree Celsius temperature increase by 2030, a level humans have never survived.
