Planet Earth has gotten windier over the last 20 years, according to a new study. Scientists looked at satellite wind measurements going back to 1985 and learned that winds have increased by about 5 percent. Very strong winds caused by storms have increased by 10 percent during the same time period. Study leader Ian Young says that it is not yet clear if our windier world is a result of global warming, or if it is a result of a cyclical pattern.
