Which kind of suggests that the future of every planet with life on it is runaway global warming, doesn't it? So what, we should stop trying to regulate our emissions because we're facing certain doom anyway? Well, according to the article, it's surfacing now because the permafrost isn't so "perma" any more... something in which humans are directly implicated. So gee, it might well be too late for us now - but it wouldn't have been 50 years ago. ...Oops. Perhaps everyone of any influence in world affairs at all since World War II needs to get together and figure out precisely how best to say to our generation, "Sorry about your planet". edit: Turns out the 500 billion tonne figure is a one-off, worst case release. Not an annual figure. Remind me, what's 500/7 again? And why exactly does "thanks to human development, mass extinction might suddenly leap one lifespan closer" mean either "it's not our fault, really it isn't, nature is evil and killing us all" or "see, there's nothing to worry about, humanity is barely having any effect at all"?
