Global warming refers to an average increase in the Earth's temperature, which in turn causes changes in climate. A warmer Earth may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans. When scientists talk about the issue of climate change, their concern is about global warming caused by human activities.
YOU can help slow global warming!
Just because we’re not absolutely certain of how more greenhouse gases will affect the Earth doesn’t mean we should sit back and do nothing.
Besides increasing greenhouse gases, burning too much gasoline and other fossil fuels creates air pollution and wastes energy. Who wants to breathe bad air, or always look up at a dirty sky?
You can help slow global warming by:
Walking, riding your bicycle, or taking the bus instead of always going by car.
Not wasting electricity (turn off the lights, the radio, the TV and the computer when you’re not using them).
Reducing, reusing or recycling all kinds of items, from soda pop cans to clothes, to save energy and raw materials.
Planting trees to help absorb excess CO2, and to provide shade and windbreaks to keep buildings at more even temperatures so they will require less energy for heating or cooling.
