This summer, the American Chemical Society's Chemical & Engineering News magazine started running movie reviews. From their critique of The Day After Tomorrow:
"To a scientist, the film is interesting because it compresses everything that could happen under an abrupt climate change scenario (and much that could not happen) into a few days, rather than the more realistic decades. A collapse of the thermohaline circulation is a low-probability, but high-impact event. If it did occur in the early 21st century, it would have a huge impact on weather.Today's New York Times has a feature about C&EN's new "Reel Science" section. Link (registration required)
Some data suggest the thermohaline circulation has already begun to slow. Certain parts of the Greenland Ice Sheet are shrinking 10 times faster than they were a few years ago, losing an average of 10 meters of elevation annually, in contrast to the previous 1 meter, and reducing the salinity of the North Atlantic."
