Faster than Predicted
Not good: In the latest issue of Science
, a bunch of climatologists argue
that climate models may actually be understating the rate of global warming.
One favored tactic of climate-change "skeptics," of course, is to argue that climate-change models are uncertain. Now, the models are far more accurate than the deniers imply, but to the extent that there is
uncertainty, as Andrew Dessler points out
, it can cut both ways. Things may actually be much worse than, say, the IPCC says. (And given the conservatism inherent in the IPCC process, the latter possibility seems more likely.)
