The cause of Mars' planetary global warming is likely the same that causes the Earth's global warming: The Sun.
Simultaneous warming on Earth and Mars suggests that our planet's recent climate changes have a natural—and not a human-induced—cause, according to one scientist's controversial theory.The androgenic global warming hysterics from the likes of Al Gore and others completely misses the point. They think that they have this global warming thing figured out, and yet they ignore or downplay the biggest player in global warming of all - the Sun. Tiny changes in solar output can have huge consequences for the climates of the planets, not just the earth. There are solar cycles, which are still being understood, but with a closer examination of Mars' climate, we're seeing that temperature rises on Earth mirror those seen on Mars. That shows that there's an external cause for the temperature rise not related to mankind's burning of fossil fuels or the emissions of so-called greenhouse gases.
Earth is currently experiencing rapid warming, which the vast majority of climate scientists says is due to humans pumping huge amounts of greenhouse gases into the atmosphere. (Get an overview: "Global Warming Fast Facts".)
Mars, too, appears to be enjoying more mild and balmy temperatures.
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 the 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.
This doesn't mean that we shouldn't do more to reduce pollution emissions or otherwise improve air quality. Switching to low sulfur fuels and shifting away from carbon based fuels would improve air quality considerably, but it would not have the effect the global warming zealots think. Indeed, the effect would be likely be zero.
Critics think that the Martian climate changes can be explained by changes in the Martian orbit, which varies over time. The problem is that critics seemingly downplay the wobbles experienced by the Earth as though they too couldn't cause climate change.
The fact that there are so many variables involved in climate change shows just how little the global warming zealots actually know about global warming - and that it is a cause for them, not about the science. They'll literally latch on to a hypothesis as though it is concrete fact and ignore and ridicule those who show that there are other factors involved that undermine or disprove the hypothesis.
