Climategate's Stubborn Facts

What are the facts? Well for starters, scientists at the Smithsonian Institution tell us that during what is known as the Medieval Optimum, the Vikings were growing grapes in Greenland. An agronomist at Virginia Tech suggest that if you are planning to start a vineyard, the roots of the vines cannot be exposed to temperatures below 25 degrees F or the vine will die. Even though there were no thermometers at the time of Eric the Red, this gives us a benchmark for reference. There are no vineyards in Greenland today because it is too cold. In fact, the Smithsonian reports that there is evidence which supports the theory that the Viking colonies later collapsed as a result of a dramatically cooling climate.

Atmospheric chemists will tell you CO2 is a trace gas in the atmosphere and is measured in parts per million. It seems a bit of a stretch that the tail can wag the dog, especially when CO2 absorbs such a narrow portion of the infrared spectrum. According to Dr. Fred Singer of the Science and Environmental Policy Project, the global climate change models cannot "hindcast" known climatic changes such as the Medieval Optimum, when good, vintage, homegrown wines could be enjoyed in Greenland.

Another "error" was admitted by the National Snow and Ice Data Center when they under-reported the amount of polar sea ice in the northern hemisphere. It seems they had a "sensor drift" which prevented the detection of ice coverage of more than 190,000 square miles -- roughly an area the size of California.
