From the smallest piece of plastic in the oceans to the largest glacier at the north or south pole, scientists can see the effects of climate change. And it is all caused by burning fossil fuels--coal, oil, and natural gas--that release carbon dioxide into our atmosphere. Fossil fuels are the fuels for the world's industry. They are the world's greatest achievement but they are also the fuel for our world's biggest problem: climate change. There is still time to protect what we have and avoid making it worse.
