We can't be the problem, right? Wrong.

One final myth to discuss in this series (I'm always happy to address others at your request): Human CO2 emissions are tiny compared with natural sources, so they can't be important.

Fact: While it's true that natural sources give off much more CO2 than humans, plants and the oceans are currently absorbing even more CO2 than they give off. Click here for more on this. It's humans' use of fossil fuels that have thrown CO2 levels off balance, since fossil fuels have been buried for hundreds of millions of years and their carbon has been out of circulation. Right now, nature is saving us from more extreme climate change than we're currently experiencing, because the oceans and plants are absorbing excess CO2. However, we're still emitting CO2 faster than natural sources can absorb it, increasing the greenhouse effect and causing climate change.

I know there are people reading this blog! (Don't worry, I don't know who you are unless you've told me, and I certainly won't share your personal info.) But all of us reading would love to hear from you--your questions, your thoughts, your ideas about climate change and what we can do about it. Thanks so much for all your support!
Stay cool,
