Mystery of the Missing Sunspots, Solved?

PRB_Ohio writes "The sun is in the middle of a century long solar minimum, and sunspots have been puzzlingly scarce for more than two years. Now, for the first time, solar physicists might understand why. The gist is that there is a 'jet stream' like phenomenon about 7,000km below the surface of the sun. The streams migrate slowly from the poles to the equator and when a jet stream reaches the critical latitude of 22 degrees, new-cycle sunspots begin to appear. Scientists at the National Solar Observatory (NSO) in Tucson, Arizona, used a technique called helioseismology to track and analyze the streams."

    What the hell will Al Gore do?

    Well maybe you missed the memo, but the problem is not "Global Warming" anymore, it's "Climate Change".

    Since the climate is always changing, Al's job is safe.

    Thing is we may face many decades of reduced agricultural output at a time when we have many mouths to feed.

    No worries though. In the time it takes for the population to triple, our agricultural output quadruples. The problem is, and always has been, distribution.

    What everybody fails to mention about Climate, is that 99% of it is caused by the Sun. Earth's spin gets the last 1%, which lets the sun do cooler stuff with wind than it could without it.

    We actually have a miniscule affect on climate. The only bad part is it may not take much at all to kill us.

    It seems that our carbon emissions are also cooling Venus and Uranus.

    Or it could be that these planets temperatures are changing independently of both the Sun and our carbon emissions?

    There's nothing like some cherry picked data to prove a point.
