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.

Humans started harnessing fossil fuels on a massive scale during the Industrial Revolution.

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.
