We do understand the #globalwarming caused by fossil fuels - for four decades it’s been going as predicted.
But we don’t understand the surprise upward leap that is happening now.
And that worries me.

@rahmstorf My Monopoly money is on methane.

We measure methane's concentration in the atmosphere pretty well. I worry that we're not measuring some of the other perfluorocarbon and other highly radiative forcing gases quite as well.

@GreenFire Do we know methane well? I thought it was far harder to get a good number for methane than we can for CO2. And that's the problem, we know it's going up a lot from sources everywhere, it's just a very broad range. The only "good" thing about the other GHGs is that their concentrations are far less even though they are far stronger per molecule. Unfortunately almost all of them are tied to feedback loops so it's all increasing.
