The planet Mars is undergoing significant global warming, new data from the National Aeronautics and Space Administration (NASA) show, lending support to many climatologists' claims that the Earth's modest warming during the past century is due primarily to a recent upsurge in solar energy.
Martian Ice Shrinking Dramatically
According to a September 20 NASA news release, "for three Mars summers in a row, deposits of frozen carbon dioxide near Mars' south pole have shrunk from the previous year's size, suggesting a climate change in progress." Because a Martian year is approximately twice as long as an Earth year, the shrinking of the Martian polar ice cap has been ongoing for at least six Earth years.
The shrinking is substantial. According to Michael Malin, principal investigator for the Mars Orbiter Camera, the polar ice cap is shrinking at "a prodigious rate."
"The images, documenting changes from 1999 to 2005, suggest the climate on Mars is presently warmer, and perhaps getting warmer still, than it was several decades or centuries ago," reported Yahoo News on September 20.
Solar Link Possible
Scientists are not sure whether the Martian warming is entirely due to Mars-specific forces or may be the result of other forces, such as increasing solar output, which would explain much of the recent asserted warming of the Earth as well.
Sallie Baliunas, chair of the Science Advisory Board at the George C. Marshall Institute, said, "Pluto, like Mars, is also undergoing warming." However, Baliunas speculated it is "likely not the sun but long-term processes on Mars and Pluto" causing the warming. However, until more information is gathered, Baliunas said, it is difficult to know for sure.
Pat Michaels, past president of the American Association of State Climatologists and senior fellow at the Cato Institute, similarly expressed a desire for more information about the Martian climate. "What is the internal dynamic that is warming Mars?" asked Michaels. "Given the fact that there are not a lot of anthropogenic greenhouse gas emissions on Mars, and given the fact that new research indicates that 10 to 30 percent estimated conservatively of Earth's recent warming is due to increased solar output, the Martian warming may support that new research."
