Permafrost / Re: Arctic Methane Release
« on: July 20, 2018, 08:28:46 PM »
Hi all, Long time no comment. But in my quick search on news re: Siberian methane, I found this very recent paper about measuring methane flux. They've realized that there are short duration bursts that get eliminated from steady-state measurements as 'outliers', so they've adapted  software from another application to include bits of bubbling-out and sweeping-up of permafrost methane. My point is that this as-yet-unreviewed paper is only proposing that this new method be implemented on all the measuring stations. That this is an indication to me that we really have so little information about how bad things are today. (Sorry if this is old news. I'm out of touch here.)
