Satellites Put the World’s Biggest Methane Emitters on the Map

Bloombert Green By Naureen S Malik October 21, 2020

GHGSat Inc. released a new methane map on Wednesday that uses data from the company’s two satellites, which were launched earlier this year and can detect methane emitted by oil and gas wells, coal mines, power plants, farms and factories. It’s part of a wave of climate surveillance that will make it possible to hold countries and companies accountable for meeting targets to reduce and eventually eliminate planet-warming pollution.

Terrifying Study Finds Melting Permafrost Could Unleash Way More Carbon Than We Thought

Science Alert CARLY CASSELLA11 FEBRUARY 2021

But now a new study has shown that a melting Arctic may actually unleash far more carbon than even our worst-case models have predicted. This is because hungry microbes, hiding in the Arctic soil, seem to be chewing their way through tiny molecular iron manacles that would otherwise be shackling carbon to the soil - meaning we've underestimated the risk of it being released into the atmosphere.

Methane, explained

Cows and bogs release methane into the atmosphere, but it's by far mostly human activity that's driving up levels of this destructive greenhouse gas.
 But methane’s chemical shape is remarkably effective at trapping heat, which means that adding just a little more methane to the atmosphere can have big impacts on how much, and how quickly, the planet warms.

Methane is a simple gas, a single carbon atom with four arms of hydrogen atoms. Its time in the atmosphere is relatively fleeting compared to other greenhouse gases like CO2—any given methane molecule, once it’s spewed into the atmosphere, lasts about a decade before it's cycled out. That’s a blip compared to the centuries that a CO2 molecule can last floating above the surface of the planet. But there are many sources of methane, so the atmospheric load is constantly being regenerated—or increased.
