Global Warming

A friend of mine was concerned that the children's pastor at a church we visit made irrelevant comments about global warming on Sunday. So, I asked HL if it was true. He couldn't remember what was said, but did recall the subject being brought up. This sparked a conversation, and I quizzed him a little to see what he new of the subject... When asked what global warming is, he responded that "it is the earth getting h-o-t." "And do you know what is causing it?", I asked "That all our trees are being cut down, the absence of clouds and the buildup of greenhouse gases." I was speechless. Never did I expect my 6 year old son to offer such an explanation. Where does he get this stuff?!? Update: He tells me that he learned on a Discovery channel show. Yes, he watches TV, but things like this allow me to justify it! ;)
