• It%26#039;s an interesting article. I particularly like this quote: %26quot;The conventional theory is that climate changes on Mars can be explained primarily by small alterations in the planet%26#039;s orbit and tilt, not by changes in the sun.
  
  %26quot;%26#039;Wobbles in the orbit of Mars are the main cause of its climate change in the current era,%26#039; Oxford%26#039;s Wilson explained. (Related: %26#039;Don%26#039;t Blame Sun for Global Warming, Study Says [September 13, 2006].)
  
  %26quot;All planets experience a few wobbles as they make their journey around the sun. Earth%26#039;s wobbles are known as Milankovitch cycles and occur on time scales of between 20,000 and 100,000 years.
  
  %26quot;These fluctuations change the tilt of Earth%26#039;s axis and its distance from the sun and are thought to be responsible for the waxing and waning of ice ages on Earth.
  
  %26quot;Mars and Earth wobble in different ways, and most scientists think it is pure coincidence that both planets are between ice ages right now.
  
  %26quot;%26#039;Mars has no [large] moon, which makes its wobbles much larger, and hence the swings in climate are greater too,%26#039; Wilson said.%26quot;
  
  
  or, if you want to know what national geographic really thinks, how %26#039;bout:

  Notice this part of the article:
  
  %26quot;Abdussamatov%26#039;s work, however, has not been well received by other climate scientists.%26quot;
  
  %26quot;His views are completely at odds with the mainstream scientific opinion,%26quot; said Colin Wilson, a planetary physicist at England%26#039;s Oxford University.
  
  %26quot;And they contradict the extensive evidence presented in the most recent IPCC [Intergovernmental Panel on Climate Change] report.%26quot;
  
  Amato Evan, a climate scientist at the University of Wisconsin, Madison, added that %26quot;the idea just isn%26#039;t supported by the theory or by the observations.%26quot;
  
  Scientist KNOW the Sun isn%26#039;t causing this. For one think, only a few of the planets are warming. If it was the Sun, they%26#039;d all be. Also we measure the solar radiation received on Earth. It%26#039;s actually decreasing slightly. Proof:

• Someone said dust storms caused Mars to heat up?
  
  When volcanos on eath cause a dust storm on Earth then it gets colder not warmer.
  
  The Liberals brains are starting to melt over this!
  
  They%26#039;re confusing dust particles with CO2 which have opposite effects on the planet!
• I am shocked National Geographic would print that. They have been pushing the pro AGW theory for quit some time.
  
  You know the lie is starting to unravel when the co-conspirators start to turn the other way.
• Yes I have seen this article--- something is going on in the solar system that we do not understand--------- yet. Even Pluto is warming and should not be due to its great distance from the sun.
• what a surprise, climate change happens on planets w/o people. what will gore/obama do?? old doc
• finally someone else with common sense!
• THANK YOU! WE HAVE SOMEONE SMART IN THIS WORLD SOMEONE WITH FACTS. I AGREE WITH THAT 100%
