Scientists review films

"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.

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."
