Satellite observations put stratospheric methane loss higher than models predicted

[John Nissen]

HI everyone,

This [1] could be an important finding. Albert has told me that levels of methane in the stratosphere have grown enormously. I think much of the methane from Arctic sources could be rising into the stratosphere thus not contributing to tropospheric level measurement. Arctic methane emissions could have been accelerating without our noticing. If so, a tipping process is becoming extremely dangerous. Efforts to remove methane from the troposphere (as discussed in yesterday's NOAC meeting) cannot slow such an acceleration. The Arctic methane has to be suppressed at source. Refreezing the Arctic has just become more urgent than ever!

Cheers, John
