HOW DO GREENHOUSE GASES MAKE THE WORLD WARMER?
Without naturally-occurring greenhouse gases (GHGs) like carbon dioxide, our planet would be downright freezing. That’s because greenhouse gases work like, well, a greenhouse. They let sunshine in and trap some of its heat in our atmosphere, making life on Earth possible today.
When the delicate balance of these GHGs is maintained between what we add and what plants absorb, the long-term average works out like Goldilocks and the Three Bears for life: Not too hot. Not too cold. Just right.
Another way to think of these gases is as a natural blanket — keeping the Earth about 60 degrees Fahrenheit (about 30 degrees Celsius) warmer than it would be normally. So, what’s the problem? Sounds like greenhouse gases are great. Who’s anti-blanket, anyway?
Well, when humans burn fossil fuels, it’s as if we’re wrapping another, not-so-natural blanket around the Earth. That’s why things are heating up and the climate is changing.
