Mars Melt Hints at Solar, Not Human, Cause for Warming, Scientist Says
Climate change hits Mars
Mars is being hit by rapid climate change and it is happening so fast that the red planet could lose its southern ice cap, writes Jonathan Leake.
Scientists from Nasa say that Mars has warmed by about 0.5C since the 1970s. This is similar to the warming experienced on Earth over approximately the same period.
Since there is no known life on Mars it suggests rapid changes in planetary climates could be natural phenomena.
The mechanism at work on Mars appears, however, to be different from that on Earth. One of the researchers, Lori Fenton, believes variations in radiation and temperature across the surface of the Red Planet are generating strong winds.
In a paper published in the journal Nature, she suggests that such winds can stir up giant dust storms, trapping heat and raising the planet’s temperature.
Fenton’s team unearthed heat maps of the Martian surface from Nasa’s Viking mission in the 1970s and compared them with maps gathered more than two decades later by Mars Global
Surveyor. They found there had been widespread changes, with some areas becoming darker.
When a surface darkens it absorbs more heat, eventually radiating that heat back to warm the thin Martian atmosphere: lighter surfaces have the opposite effect. The temperature differences between the two are thought to be stirring up more winds, and dust, creating a cycle that is warming the planet.

And Tibor R. Machan writes in The Orange Grove, "Well, I don't know about you, but it is my very strong impression that Mars is not teeming with gasoline-powered traffic just now. Exactly what the folks up there are using for fuel I do not know but I have heard on good authority that none of what they use is causing the warming of the planet. Indeed, I have heard rumors that there is no one up there using any fuel combustion for anything, not a soul. The warming seems to be happening quite without the influence of Martians, let alone Earthlings."
"Bloomberg News reports, "At a time when people are concerned about warming of the Earth, the Mars report shows one way that planets can grow hotter."
John Johnson Jr. of Times writes,"It turns out you don't need belching smokestacks and city-choking traffic to heat up a planet. Changes in surface reflectivity may also do the trick, according to research published Thursday in the journal Nature.
The research team, composed of scientists from NASA's Ames Research Center in Northern California and the U.S. Geological Survey, compared images of Mars taken by the Viking missions in the 1970s to pictures taken a quarter century later by Mars Global Surveyor."
I say who does man think he is? Is man so vain that he thinks he controls the Universe? God controls it all. Man's ego has gotten vastly out of control. Human vanity is what pushes the advancement of "Global Warming Fear Induction" and it's laudable. We are not even specks in this universe yet so many think we have such control. Baffling!
