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.

Individuals, businesses, and organizations across the world will be
participating. Earth Hour is a
demonstration of how much we can do to cut back power use and prevent
climate change if we all work together.
Do you plan to participate?

A new study predicts that one out of every five lizard species will be extinct by 2080 if global warming continues. When it gets too hot to be in the sun, lizards must hide in the shade and rest, because they are cold-blooded animals and can’t adjust their body temperature. If the Earth’s temperature gets warmer, lizards will spend more time hiding in the shade and less time hunting or laying eggs. Warmer temperatures may mean that lizards starve to death.
