explanation of Global Warming for children

There were some good (verbal) responses on our recent post with the child-like explanation of nuclear meltdown, so today we’re going to show a video that explains what causes Global Warming.  This is a simplified version, at a level anyone can understand.  (So if you still don’t get it, you’re obviously making things too complicated.)

FYI, this is from an episode of Futurama, in case you were wondering.
