I hate blogs that force you to jump through hoops to post comments, especially when those hoops don’t work. So I could mail Gareth to complain about my inability to comment on “The inner mounting flame” but I’m too impatient, so instead I’ll just post my minor snark here:
It sez: “This is a global event now, and the inertia for more permafrost melt is increasing.” Not good news.
I agree. It isn’t good news. It means that ecologists (or, to be slightly fairer, one particular ecologist) doesn’t understand the difference between inertia and momentum.
Meanwhile, Gareth asks So why are we worried? Take a look at the latest graph of global methane concentrations, and note the strong upwards jag since 2007… And if you do look at the graph, you’ll see an increase of perhaps 20 ppb from 2006-8 ish. Which is about 0.6%/yr. Is that really a strong upwards jag? It looks strong compared to the near-flatness in the previous decade, true. But compared to SRES, it is low.
