In fact, some of the other planets have worlds orbiting them that are even bigger than the earth [FALSE - no satellites in the Solar System are larger than Earth. The largest moon is Ganymede, which is slightly larger than Mercury... which makes it about 1/3 the size of Earth], all possess gravity, just like we do.... . . We presently orbit the sun at 93 million miles, we call that distance one parsec. [FALSE - A parsec (parallax second) is a unit of distance used in astronomy, equal to about 3.25 light years (3.08 × 10 16 meters). One parsec corresponds to the distance at which the mean radius of the earth's orbit subtends an angle of one second of arc. 93 million miles, the distance from the Earth to the Sun, is an AU (Astronomical Unit).]
If this is the level of this guy's astronomical fact checking, I am leery of his other facts as well.
It certainly gives me a reason why he states that Anthropogenic Global Warming is a viable theory... his facts are really screwed up.
This doesn't mean that the added CO2 from man-made sources (which he analyzes incorrectly) is going to push into catastrophe. It isn't.
Please see the caveat I have posted at the link (http://www.freerepublic.com/focus/chat/1978643/posts?page=14#14) in response to comments by you and palmer.
