Atmospheric methane: Comparison between methane’s record in 2006-2022 and during glacial terminations.

Abstract

The air is getting hotter. There's a rumbling in the skies. I've been wading through the high muddy water, With the heat rising in my eyes. Bob Dylan: Trying to get to Heaven before they close the door.Plain Language Summary Atmospheric methane's unprecedented current growth, which in part may be driven by surging wetland emissions, has strong similarities to ice core methane records during glacial-interglacial "termination" events marking global reorganizations of the planetary climate system. Here we compare current and termination-event methane records to test the hypothesis that a termination-scale change may currently be in progress.NISBET ET AL.
