What is global warming for kids?
The Planet Earth goes through natural warming and cooling cycles that take tens of thousands of years. Our last cooling cycle covered most of the land with deadly glaciers, crushing the forests and destroying land needed by animals. Then, ten thousand years ago, the deadly ice age ended and the Earth started warming again. As the glaciers were melted, forests grew and animals had new places to live. We now have cities built in places that were once crushed under a mile of ice. Thanks to global warming, caused by the Sun’s warming rays, we now have lots of places to live and grow food. The sun is also warming other planets in our solar system. We don’t live there, so it doesn’t matter to us much. But some day it might.
