2  Climate change is a change in the statistical distribution of weather over periods of time that range from decades to millions of years.  It can be a change in the average weather or a change in the distribution of weather events around an average (for example, greater or fewer extreme weather events). Climate change may be limited to a specific region, or may occur across the whole Earth. It can be caused by recurring,

3  It can be caused by recurring, often cyclical climate patterns such as El Niño- Southern Oscillation, or come in the form of more singular events such as the Dust Bowl.

4  The earth has warmed up more than 47% over the last 100 years. These more recent changes in climate change can't be explained by natural causes, only by human behaviour.

5 Before 100 years Today

6  Climate change is already happening and represents one of the greatest environmental, social and economic threats facing the planet.

7  For the first time in human history, people are changing the Earth’s climate by emitting so-called greenhouse gases into the atmosphere. The main cause is the dramatic increase in the use of fossil fuels (coal, oil and natural gas) since the Industrial Revolution.

8  The Earth’s climate is always changing. Only 20,000 years ago, much of Northern Europe was covered in an enormous glacier that was up to three kilometers thick! The Alps and the Pyrenees mountains were covered with smaller ice caps. Sudden climate shifts happened quite frequently during the Ice Age, and made the ice expand or contract.

10  People are doing many things to try to stop global warming. One thing people are doing is carpooling. Carpooling is driving with someone to a place that you are both going to. This minimizes the amount of greenhouse gases put into the air by a car.

11 Although adults do many things to help stop global warming, kids can do just as much. Kids can’t do hard things like making a law, but we can do easier things like not watching as much TV. You can listen to your parents when they say, turn off your lights or go play outside. Listening to them and actually trying to help can help you, your environment, and the world.
