It’s clear that we need to make the switch to clean, reliable sources of renewable energy like solar and wind. Unlike fossil fuels, renewables don’t add greenhouse gases to our atmosphere.

When we burn these fossil fuels, the carbon combines with oxygen to make carbon dioxide. This extra carbon dioxide (and other GHGs like methane) traps more and more heat in our atmosphere.

Scientists think that the things people do that send greenhouse gases into the air are making our planet warmer.
