Kenneth Tapping of our own National Research Council, who oversees a giant radio telescope focused on the sun, is convinced we are in for a long period of severely cold weather if sunspot activity does not pick up soon.

The last time the sun was this inactive, Earth suffered the Little Ice Age that lasted about five centuries and ended in 1850. Crops failed through killer frosts and drought. Famine, plague and war were widespread. Harbours froze, so did rivers, and trade ceased.

It's way too early to claim the same is about to happen again, but then it's way too early for the hysteria of the global warmers, too.
