Earth's Magnetic Field Changes Climate

From Discover News.com (Jan. 13, 2009):

The Earth's climate has been significantly affected by the planet's magnetic field, according to a Danish study published Monday that is unlikely to challenge the notion that human emissions are largely responsible for global warming.

"Our results show a strong [my italics] correlation between the strength of the Earth's magnetic field and the amount of precipitation in the tropics," one of the two Danish geophysicists behind the study, Mads Faurschou Knudsen of the geology department at Aarhus University in western Denmark, told the Videnskab journal.

Well isn't that surprising! Not! How dare that darn magnetic field that blocks solar wind from reaching the earth increase global warming! I remember reading that Mars has global warming on it too. Well Mars has a magnetic field too. I wonder if its magnetic field is causing global warming for it. Global warming on Mars can't be man-made. No people are on Mars. The only other thing in common with both planets is the sun. Hmmmm. The article says that the climate is an "incredible complex system." Duh. Ask any meteorologist and they would agree.
