CO2 Increase Tied to Human Activity

Global warming has been in the news a lot lately. It’s one of those things that is so politically charged that it becomes more of an “issue” than a scientific study. WorldChanging has a great summary in layman’s terms of an article on how we know human activity is causing the increase of carbon dioxide (CO2) in the atmosphere. Of course, we also know for sure that CO2 is a greenhouse gas which helps trap heat from the sun. Politics aside, it was an interesting article, and it’s worth checking out.
