Climate is the average weather usually taken over a 30-year time period for a particular region and time period. Climate is not the same as weather, but rather, it is the average pattern of weather for a particular region. Weather describes the short-term state of the atmosphere (大气).

The climate is changing. Many agreed that climate change may be one of the greatest threats (威胁) facing the planet. Recent years show increasing temperatures in various regions, and/or increasing extremities (极端性) in weather patterns.

Is the Earth getting warmer? Yes! The Earth has warmed by about 1°F over the past 100 years. But why? Well, scientists are not exactly sure. The Earth could be getting warmer on its own, but many of the world’s leading climate scientists think that things people do are helping to make the Earth warmer.

Global Warming may be a big problem, but can you make a difference? Yes! There are several little things you can do to make a difference. Try carpooling. This will help reduce the amount of fossil fuels going into the atmosphere. Whenever you use electricity, you help put greenhouse gases into the air. Turn off lights, the television, and the computer when you are through with them. Also, planting trees is fun and a great way to reduce greenhouse gases. Trees absorb carbon dioxide, a greenhouse gas, from the air. Finally, don’t forget about recycling.
