There are still sadly many people out there who have decided to believe the oil industry, big business, and our conservative government rather than the scientific community about global warming. It's real, it's happening, and we need to do something about it. Next time some idiot tells you that there's no proof of global warming, direct them to this guy's channel. He does an excellent job of debunking the myths out there and explaining the science. In this video he demonstrates that the concept of CO2 causing global warming is so simple, even a child can (and does) understand it.
