Unexpected Methane Surge

According to Climate Nexus,

An unexpected surge in global atmospheric methane is threatening to erase the anticipated gains of the Paris Climate Agreement. This past April NOAA posted preliminary data documenting an historic leap in the global level of atmospheric methane in 2018, underscoring a recent wave of science and data reporting that previously stable global methane levels have unexpectedly surged in recent years.

The scientific community recently responded to the surge into two high profile publications by calling for a reduction in methane emissions from the natural gas system…

It is not clear where this methane is coming from, but most bets are on wetlands that have shifted from being greenhouse gas sinks (or neutral) to being greenhouse gas emitters. Methane is a bad greenhouse gas while it lasts (decades) but eventually changes into CO2 and water. The CO2, of course, stays in the atmosphere for much much longer. So, this is really like CO2 release but with a giant kick in the gut right out of the gate.

  1. I wonder if it has something to do with the record breaking heat in Alaska and likely beyond and the melting of permafrost there – in whole or part? See :

    Which is also affecting the albedo of the regions there as white reflective ice is replaced by dark land or darker water as another escalating feedback mechanism. 🙁
