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.

    I guess our SUV's are also the cause for MARS' global warming.
    I hate it when that happens.[:D]

    You should listen to Art Bell more often. He's had many Martians on the air
    telling of their experiences on and around Mars.[:o)]

    That's precisely why I don't worry about how much I drink when I drive.

    It's proven that motor skills deteriorate naturally as BAC increases.

    But nobody has ever proven that BAC > 0.08 kills. It is the CAR or sometimes the WALL or at other times the TREE that kills in that case, not the BAC.

    Can somebody get me another drink, please?

    Why listen to Art Bell? Just ask *-R-Done here yourself. They're the same person.

    Swing by my place, and you can have an entire 1/2 liter of Captain Morgan Original all to yourself.

    Must be caused by the probes we sent there.[:0] Guess that is our fault too!!

    It's Bush's fault for invading Iraq.

    Ah! Ha! a new cause for Al Gore! He can get all the liberals to send him more money to resolve the Mars global warming problem. He can make a movie and write a book. Will make a fortune and can buy another 6,000 sq ft home that uses 6 mg wts of electricity.

    Got a better idea...........Let's send Al Gore to Mars. He can generate enough wind to reverse the direction and force the temperature to drop. Maybe Hillary and the Queen Bee will fit in the same space ship.

    Now, if we can just get algore and all the high priests and priestesses of the human-caused global warming religion to HIT MARS, as well, then we can go on with life as usual here on the 3rd rock.

    I posted this a few months ago...it seems as if the "warming" that we are experiencing is a solar event.
