Satellites Show Earth has a Fever

According to a NASA study, global average temperature increased by 0.43 Celsius per decade over the last 18 years. NASA scientists say that the new satellite data comes from measurements of the Earth's "skin temperature."

NASA has put out a list of things that people all over the planet can do in order to help Earth's fever come down. Their recommendations include giving the Earth a cool sponge bath and some Tylenol, or letting the Earth "rest" for a while. "A couple hundred million years ought to do the trick," NASA scientists said.
