    New scientific study on the sun in global warming.

    There has been some discussion on the sun's effects on global warming, so i wanted to throw in a paper that is relevant.

    http://sciencenow.sciencemag.org/cgi...ull/2008/312/3

    Don't blame the sun for recent global warming. A new analysis, based on historical data rather than computer simulations, shows that our star's role in climate change has been vastly overtaken by other factors, particularly the human-induced buildup of greenhouse gases.

    We get our warmth from the sun, sure, but our climate results from a complex and precarious balance of additional factors, including ocean currents, winds, the amount of snow and ice cover, and even Earth's orbit and rotational wobble. It's well-known that our climate has been warming over the past century--a situation most researchers blame on human-induced buildup of carbon dioxide, methane, and other greenhouse gases. Studies have shown that the sun was a driving factor in climate change in preindustrial times, but some researchers have wondered whether changes in the sun's intensity are continuing to play a major role, possibly by hitting the planet with more heat than normal.

    To help nail down the effect of solar radiation, geophysicist Mike Lockwood of the University of Southampton, U.K., examined data available since 1955 on the monthly average output of the sun, including sunspots, magnetic activity, and cosmic-ray variations. Then he compared those data, month by month, with average global temperature records, as well as El Niño- and La Niña-induced weather cycles and the atmospheric effects of major volcanic eruptions. The result, Lockwood and colleagues report in two papers published online this week in the Proceedings of the Royal Society A, is that for the past half-century, the sun has exerted only a small influence on climate--about 3% compared with the warming influence of greenhouse gases and natural climate cycles (see illustration).

    Lockwood says a key advantage of his approach is that he relied on hard data rather than computer models. "One problem that crops up [in the climate discussion] is that scientists use complex models that nonspecialists don't understand and therefore don't trust," he explains.

    Lockwood's research represents "a solid look at whether global temperature increases are being driven by changes in the brightness of the sun," says geophysicist Dáithí Stone of the University of Oxford in the U.K. The work suggests that "there is basically no way that this can be the case," he says.

    that makes no logic

    This is interesting, I figuerd it likely wasnt the sun from the begining, but I still think this focus on global warming takes the focus off the greatest threat to human existance, ourselves.

    How about CO2 absorption from ground cover, like grasses?

    UVs are hard core outside right now. Lets fight global warming., Reduce reuse recycle. Free ,clean energy sources
    Quit reading my mind!

    I hate to say "I told you so" but there's more and more proof coming out everyday that debunks the Global Warming theory. My question is will people learn from this example or will they continue to be sheep because some quack came up with an unprovable theory based on limited and recent data?

    Does that mean we should give up on renewable resources...no! I think they are just as important regardless of the agenda-based Global Warming theory. We should be good stewards of this Earth and our country needs energy independence.

    I still say its irrelevant if global warming is a problem, global warming just distracts us from the real issue which doesnt have any "easy" or "acceptable" answers and that is there are too many people on earth, probably twice as many as can live in a sustainable fashion. If we have few people we would have a lower impact on the planet, thus making issues like global warming much more manageable.

    The greenhouse gas - global warming connection is pretty compelling, even if the results are not known with 100% certainty. It's an infinitely greater threat than terrorism and, if we had a vertebrate for president, we might have been reducing the risk for the last 7 years instead of making things worse. Actually, if our other recent presidents had been vertebrates, we'd be way better off, not just regarding climate, but in many other ways that would be improved with less dependence on energy, cars, trucks and the military necessary to keep everything moving.

    Aww, nice try, but once again, wrong.

    See the same site, less than two months later: http://news.nationalgeographic.com/n...s-warming.html

    And a more comprehensive analysis: http://www.realclimate.org/index.php?p=192

    Wow, I didn't know that the entire community of reputable climatologists consisted of "one quack".

    Nor did I know that 144,000 years of data, with multiple confirming sources, was "limited and recent data".



    Given how badly you embarrassed yourself in our prior confrontations over evolution, I'd suggest you simply not talk about science anymore, as it's clear you don't have the slightest clue about it.
