Sun spots (so what?)

There are actually things more important than the pregnancy of Gov. Palin's teenage daughter. For instance, sun spot activity of either zero or one-half for the month of August may have significant implications for the Earth's climate. There is significant evidence that sun spot activity has influence on global climate. Periods of heightened activity such as we have experienced since the 1940's lead to warming, periods of decreasing activity lead to cooling and perhaps even increasing glaciation. If activity continues at this level we may be facing another minimum.

Since it seems obvious that the most important cause of any temperature shift is the sun, this is something that we should pay attention to. There is not anything that can be done, like carbon reduction, (well maybe increasing carbon would attenuate some of the cooling effect,) but it at least gives a warning and allows for preparation.

I heard the Farmer's Almanac uses sunspot activity to predict the winter weather... and they say it will be a very cold winter. We'll see.
