  1. There is no proof of Global warming if you look at satellite data. "A lot of scientific data" is not proof. "Scientific data" could mean anything. Anyone can create data. But proof from a reliable source (Satellite data, versus these cheesy ground temperature data) shows that global warming is not in existence.

    Besides, *some* portions of the earth ARE warming. Not the whole thing. IT'S THE EARTH'S NATURAL CYCLE! How can you, a supposed "scientist" not know this?????
