The Warm Turns

Global thermometers stopped rising after 1998, and have plummeted in the last two years by more than 0.5 degrees Celsius. The 2007-2008 temperature drop was not predicted by global climate models. But it was predictable by a decline in sunspot activity since 2000.

When the sun is active, it's not uncommon to see sunspot numbers of 100 or more in a single month. Every 11 years, activity slows, and numbers briefly drop near zero. Normally sunspots return very quickly, as a new cycle begins. But this year, the start of a new cycle, the sun has been eerily quiet.

The first seven months averaged a sunspot count of only three and in August there were no sunspots at all — zero — something that has not occurred since 1913.

According to the publication Daily Tech, in the past 1,000 years, three previous such events — what are called the Dalton, Maunder and Sporer Minimums — have all led to rapid cooling. One was large enough to be called the Little Ice Age (1500-1750).
