- What is Global Warming? -
..........The Earth's climate has been changing
................constantly over its 5 billion year history
Sometimes, the climate has warmed so that the oceans have risen and covered much of the Earth. At other times the climate has cooled and the Earth experienced periods of extreme glaciation.
Each of the changes may seem extreme, but they usually occurred slowly over many thousands of years
Recently the Earth's climate is changing at a much faster pace. It may seem hard to believe that people can actually change the Earth's climate but some scientists think our actions are making the planet warmer.
Below are the basics that will help you better understand
the Science of Climate Change & Global Warming
