A Hotter Sun May Be Contributing To Global Warming

no reason to be here writes "The sun seems to be getting hotter. Total radiation output has increased .05% per decade since the 1970s. This article over at Yahoo! News has the scoop. Though .05% may not seem like much, if it has been going on for the last century or more (and circumstantial evidence suggest that it has), it could be a significant factor in the increase in global average temperature noticed during the 20th century."

      You know, back in the 1970s, the Green movement was most worried about global cooling. We're overdue for another ice age, they apparently come every 10,000 years or so. The Green's prescription for staving off this threat was to burn less fossil fuel, cut down fewer trees and so on. Fast forward to the 90s and global warming is in vogue. The cure? Burn less fossil fuel, etc.

      It's beginning to look like their agenda all along was to slow economic activity, and concern about the environment was only ever a vehicle for pushing that agenda. So don't feel bad about questioning the Green orthodoxy, because it's changed 180-degrees in the not too distant past, and they probably don't even believe it themselves.

      Not that we shouldn't conserve fossil fuels; they're going to run out sooner or later. And pollution is bad, it just makes cities unpleasant. And I like furry animals as much as the next man, and I'd rather they weren't driven to extinction. But fight these things for a real reason, not one that doesn't hold stand up to scrutiny.

    One of the more interesting things my geologist friend pointed out to me was the fossel recond in Michigan (for our European friends, Michigan is a state on the border with Canada). We have palm tree fossels all over Michigan. Our current climate won't support palms now but some time long ago Michigan was much warmer than it is now.

    He also mentioned that Michigan was buried under about a mile of ice at one time too.

    These weather changes were long before man came on the scene. I'm all for Michigan becoming tropical again but that is likely to cause problems for the southern part of the US.

    The weather is what it is. To the degree that global warning is occurring, the question is what the cause or causes are of that change.

    I'm prepared to believe that CO2 is the primary culprit, but I regard as a question of science, not blind religious faith. The mindset you and "aepervius" seem to have, that CO2 must be treated as the cause of climate change, regardless of what new facts emerge, is, well, embarassing.

    On a human timescale, no the earth is not moving closer to the sun. The orbits of the planets in our solar system are stable relative to any conceivable timescale. The sun is exerting some forces on the earth - very slowly decreasing our the rate that we spin on our axis, for example.

    In thousands upon thousands of years, the earth will only turn on its axis once per year, always keeping the same face toward the sun as it rolls along its solar orbit. This is "tidal lock" much like the earth has achieved over the moon.

    The article says

    That does not mean industrial pollution has not been a significant factor, Willson cautioned.

    so, no, this

    • is not just some evil US/oil company plot to discredit the idea that greenhouse gases contribute to global warming;
    • is not an indication that all those people saying that greenhouse gases contribute to global warming were wrong and we don't have to worry about continuing to burn fossil fuels.

    Note, for instance, that the article also says

    In what could be the simplest explanation for one component of global warming, a new study shows the Sun's radiation has increased by .05 percent per decade since the late 1970s.

    The increase would only be significant to Earth's climate if it has been going on for a century or more, said study leader Richard Willson, a Columbia University researcher also affiliated with NASA's Goddard Institute for Space Studies.

    (emphasis mine).

    I.e., they have only observed it over a approximately 20-year period, so they don't know whether it's been going on for a century or more, but if it hasn't, it wouldn't make a significant difference to the climate.

    I read that nature is already doing something like that, as per Gaia theory. It's in the Feb. 2003 issue of Discover magazine, P 17. To paraphrase:

    The sun's brightness has increased ~30% since it's birth because of the helium ash piling up. On early earth, there was a larger amount of CO2 in the atmosphere to keep us at a reasonable surface temperature.

    As the sun gets brighter, the energy influx increases and so more carbon dioxide is taken out of the atmosphere to maintain a steady temperature.

    In about a billion years, almost all CO2 will have been removed from the atmosphere. From there, the continuing increase in energy will cause our oceans to evaporate and then boil. The water will go up into the stratosphere, where high energy radiation will break it into hydrogen and oxygen. The hydrogen will escape and earth as we know it will be sterilized. Sounds lovely, doesn't it?

    Seeing as the sun will remain stable for another 4 billion years though, I suppose we could use some sort of scheme to (very) gradually slingshot earth farther out into the solar system. For a while we'd probably park 60 degrees ahead of Mars, then commit suicide by trying to fly through the asteroid belt :)

    some of this is from an earlier post earlier post

    Let me say it again. Look at these graphs. The data, taken from ice core studies, shows four ice-ages in the past 400k years. For each dip of the CO2 graph there is a similar dip in the temperature graph showing a high degree of correlation. The extended CO2 graph shows an enormous increase in CO2, over the past century, well outside the range of the past 400k years. This recent rise is almost a vertical jump, indicating we may be changing the climate drastically.

    It is possible that the sun has some effect in triggering these cycles but these graphs show such a large correlation between CO2 and temperature that it is impossible not to believe the scientists of the IPCC. Yes, human activity is causing global warming. (In the UK we experience this now as global wetting - with increased heavy rainshowers).

    Its a lie. Its the Republicans, plain and simple. And if it IS the sun, then the Republicans are who made the sun hotter. And if the sun is hotter due to a natural phenomenon, then the Republicans sped it up with their capitalism. If we didn't drill for oil, the sun wouldn't be so hot. The sun is heating up because of greenhouse gases. Its the Conservative's fault the sun is hotter, it was the tax cut that caused it. SUV's. Too many in on the planet causes more tidal friction on the sun, so its the SUV's fault, which is the Republican's fault because they own stock in the companies that make the SUV's, who are being irresponsible for giving the public what it wants, since everyone knows only Hollywood types should drive SUV's, not these damn soccer moms and farmers. Its because of the decline of endangered species. The sun is warming up because of drilling in ANWR, which hasn't started yet. The sun is part of the vast right wing conspiracy. Its the Republican's war causing it. Its because the sun is angery at us for our ways.
