Ok, found our original conversation: My "Mars" post Your rebuttal I had researched a post about the rest of the solar system, but apparently I never actually posted it. From my partial notes, I still have the below information. This is not a complete enumeration of data that tends to support a "solar system wide" change in planetary weather patterns, but should be enough to prove the possibility of the point I was trying to make: By Robert Roy Britt Senior Science Writer posted: 09 October 2002 01:25 p.m. ET Pluto is undergoing global warming in its thin atmosphere even as it moves farther from the Sun on its long, odd-shaped orbit. Pluto's atmospheric pressure has tripled over the past 14 years, indicating a stark temperature rise, the researchers said. The change is likely a seasonal event, much as seasons on Earth change as the hemispheres alter their inclination to the Sun during the planet's annual orbit. They suspect the average surface temperature increased about 3.5 degrees Fahrenheit, or slightly less than 2 degrees Celsius. New Storm on Jupiter Hints at Climate Change By Sara Goudarzi Staff Writer posted: 04 May 2006 01:00 pm ET Some astronomers believe that the spots dredge up material deep below Jupiter's clouds and lift it to where the Sun's ultraviolet light chemically alters it to give it a red hue. The latest images could provide evidence that Jupiter is in the midst of a global change that can modify temperatures by as much as 10 degrees Fahrenheit on different parts of the globe. The study was led jointly by Imke de Pater and Philip Marcus of University of California, Berkeley. MOC Observes Changes in the South Polar Cap: Evidence for Recent Climate Change on Mars MGS MOC Release No. MOC2-297, 6 December 2001 Extracts: The residual martian south polar cap is changing. The fact that it is changing suggests that Mars may have major, global climate changes that are occurring on the same time scales as Earth's most recent climate shifts, including the last Ice Age. ... These new observations indicate that the south polar residual cap is not permanent. It is disappearing, a little bit more each southern spring and summer season. At the present rate, a layer 3 m thick can be completely eroded away in a few tens of martian years. Since each layer is equivalent to about 1% of the mass of the present atmosphere (which is 95% carbon dioxide), if sufficient carbon dioxide is buried in the south polar cap, the mass of the atmosphere could double in a few hundred to a thousand Mars years. That could lead to profound changes in the environment. Global Warming Detected on Triton (scienceagogo.com) 28 June 1998 Extracts: The Earth is not alone in suffering global warming. According to observations made by NASA's Hubble Space Telescope and several ground-based instruments, temperatures on Neptune's largest moon have increased dramatically since the Voyager space probe swung by in 1989. So much so, in fact, that Triton's surface of frozen nitrogen is turning into gas, making its thin atmosphere denser by the day. "At least since 1989, Triton has been undergoing a period of global warming," confirms astronomer James Elliot, professor of Earth, Atmospheric and Planetary Sciences at Massachusetts Institute of Technology. "Percentage-wise, it's a very large increase." Elliot and colleagues from the Lowell Observatory and Williams College report their findings in the June 25 issue of the journal Nature. Triton's 5 percent increase on the absolute temperature scale from about -392 to -389 degrees Fahrenheit would be like the Earth experiencing a jump of some 22 degrees Fahrenheit in just nine years. *** When I read your pdf file, the over all impression I get is that the authors are advancing another possible theory to explain only the changes in Mars southern CO2 cap. As a very initial theory, and without a lot of hard data. Pretty neat theory, actually. Good skull sweat ... but far from sufficient to be making definitive statements that you seem to have made about "disproving" the shrinking of the icecap. In conjuction with the apparent weather changes on other planets (which I'll also allow are not "proven beyond a shadow of a doubt" either), and the changes in solar radiation patterns, I think the possibility that at least part of the current apparent warming trend of the Earth may be due to causes other than industrial society should be considered. If you really need a detailed Fisking of your "Mars" article, I can likely provide it, although perhaps a short summary on your part might be in order for now? FirmKY
