After our previous article on a
warning from NASA that we're doomed. Here is another spin on it.
Earth is currently warming up, no one disagrees with that. It is the how that is in contention. It seems that Mars is also experiencing a warming trend.
In 2005 data from NASA's Mars Global Surveyor and Odyssey missions revealed that the carbon dioxide "ice caps" near Mars's South Pole had been diminishing for three summers in a row.
Habibullo Abdussamatov, head of space research at St. Petersburg's Pulkovo Astronomical Observatory in Russia, says the Mars data is evidence that the current global warming on Earth is being caused by changes in the sun.
"The long-term increase in solar irradiance is heating both Earth and Mars," he said.
Abdussamatov believes that changes in the sun's heat output can account for almost all the climate changes we see on both planets.
Mars and Earth, for instance, has experienced periodic ice ages throughout their histories.
"Man-made greenhouse warming has made a small contribution to the warming seen on Earth in recent years, but it cannot compete with the increase in solar irradiance," Abdussamatov said.
So what are you to believe? What should you do about it?
Buy your SUV/Sports car? Buy an economy car?
Here is another way to cut carbon output and pollution.
Stop having so many damned children!
Fewer children, less cars, less resources consumed, less pollution…
