No, We're Not Headed For a New Ice Age

purkinje writes "Unusual calm in the solar cycle — called a solar activity minimum — has sparked claims that the Sun will cool the Earth, leading us into a new ice age. While Europe did experience a Little Ice Age during a solar activity minimum three centuries ago, the connection between sunspots and climate is a lot more complicated, and it's unlikely this change in the Sun's activity will cool Earth down — or even affect the climate at all. Plus, any cooling that might come from this would be less than the global warming that's been going on. So don't pull out that parka yet; a new ice age seems more than unlikely."

    Probably the biggest thing sparking skepticism about man-made global warming are articles like these. "Please ignore that fiery nuclear furnace behind the curtain."

    Just admit you don't have everything figured out. I know that may give rise to healthy skepticism. People may not want to spend trillions in dollars to fix a problem you aren't certain about.

    As an aside, it is interesting that the other time of cold temperatures (late 18th century) corresponds to lower sun spot activity.

      Nice strawman argument. A 1% change in cloudiness would account for 100% of the surface temperature variability that we have seen since 1880. The climate models ignore the effects of changes in solar magnetic activity on cloudiness.

    That we've been in a cooling period since 1998 that has reversed ALL of the observed warming that took place previously in the early 20th Century and more.

    The assertion that the calm Sun activity won't reverse the warming is true only in that there is no longer any warming to reverse.

    Carbon dioxide concentrations would have to increase by about 30 times to actually cause health issues.

    But if you look at the IPCC reports, you'll find that the climate science IS saying "We haven't figured it all out",

    So, You are saying that even though the IPCC isn't sure if GW even exists, they still need to devistate economies and destroy industries in the off change that something might possibly be happening, but they're not really sure how or why.

    Sounds like a good reason for Al Gore to rake in billions with his carbon credits company.

    What is it with that bloody Al Gore-fixation? Can we discuss science without this particular derailment for once? Did he touch you in some bad place or something? What Gore says or does has no bearing at all at the science behind climate change, in the end.
