Can’t relate Mars, Earth

To the editor:

I question Mr. Reed’s assertions in his October 2007 letter in which he labeled global warming a hoax. Major evidence for his opinion was that the hottest year was 1934. A recent article in the Democrat and Chronicle (November 26, 2007) stated that this year is on track to be the warmest in 127 years and that the previous record was 2003.

Mr. Reed also builds his case against global warming by hinting that the Martian glaciers are melting. Comparing our climate to that of Mars is a big leap. Mars undergoes major shifts in its axis of rotation — in effect its poles change. Many times in the past the poles of Mars have pointed more directly at the sun, consequently melting its ice caps. Our Earth does not shift its axis very much because, lucky for us, our large moon keeps things more stable. The two tiny Martian moons are only 8.3 miles and 4.6 miles across at their longest points, so their minute gravity can not stabilize the tilt of Mars. In a previous letter (June 2007), I described why Mars is currently warming.
