Joseph Romm is my favorite source these days for insightful commentary on global warming. He links today to a draft essay from James Hansen and the boys at NASA: If It’s That Warm, How Come It’s So Damned Cold? (PDF). He excerpts the following graph:
…and quotes the following passage that I find highly relevant to recent discussions hereabouts:
Why are some people so readily convinced of a false conclusion, that the world is really experiencing a cooling trend? That gullibility probably has a lot to do with regional short‐term temperature fluctuations, which are an order of magnitude larger than global average annual anomalies.
As Romm concludes, “Weather isn’t climate.” For people who get their science from Rupert Murdoch’s infotainment outlets, that fact apparently is easy to overlook.
