Unusually Bad Weather Doomed Scott

In 1912, Robert Scott led an expedition on an arduous 1,440-kilometer trek to the South Pole, only to be beaten to his goal by a Norwegian group led by Roald Amundsen. Scott perished in the harsh conditions trying to get back home.

New research indicates that the weather was unusually harsh - even by Antarctic standards - during Scott's adventure, and may have played an even greater role in his demise than previously appreciated.

U.S. scientists analyzed data gathered from the pole using automated weather stations for more than a decade. They discovered that temperatures Scott reported - below minus 30 degrees Celsius on average - were 10 degrees to 20 degrees below those usually recorded during that time of year.

"These remarkably cold temperatures likely contributed substantially to the exhaustion and frostbite Scott and his companions endured," they wrote in the Nov. 9 issue of the Proceedings of the National Academy of Sciences.
