Agree fully with you. In fact, a few years ago, the greenhouse in my town failed when a tree limb fell on it during an ice storm, breaking some glass on the roof, and causing a mini-ice age. Even the sun couldn’t offset the below-freezing temps which affected the greenhouse as a result. Real bummer was that all the dinosaurs in the exhibit we had died as well.

Most large climate variance is caused by Milankovitch Cycles. The last glaciation and the current inter-glaciation are the result of those cycles. According to the current trend in Milankovitch cycles, we should be cooling and heading toward a glacial period in 10,000 years or so. The warming we’ve seen is in spite of the known warming forcings like increased sun output and the change in Earth’s precession.
