The Guardian Weekly (March 10, 2023) –

It’s no secret that methane is one of the most potent greenhouse gases, with scientists attributing 25% of global heating to its atmospheric release. A new Guardian analysis by environment editor Damian Carrington lays bare the extent of the problem, identifying more than 1,000 of the world’s worst emitters.

But methane is also a double-edged sword: while it traps 80 times more heat than carbon dioxide, it fades from the atmosphere in about a decade, far faster than the century or more taken by CO₂, which is why urgent action to tackle leaks would be so effective in the push to limit global heating.
