Global Climate Change
Global climate change is a trend in which the climate on our planet is changing. Major shifts include an increase in average temperature over the whole planet, a rise in sea levels and changes in weather patterns. Scientists believe that global climate change is caused in large part by human activities that have increased the amount of heat-trapping gases in our Earth's atmosphere.
