The Methane 'Time Bomb': How big a concern?

I thought this was going to be depressing, but to my delight it wasn't.

I glanced at a video the other day which said it's too late, methane is rising from the polar caps and runaway thermal warming probably can't be stopped - but don't panic, because we still here a chance. I wrote underneath the video that if we green the arid parts of the world by grazing livestock on it properly, it will soak up all the excess carbon we produce.

It's beautiful here in London right now, with a splendid sunset. Let's hope we don't mess it up.

Anyway, with so much bad news about with the elites wanting perpetual war, this video cheered my up.
