As I showed yesterday, NCAR has this map showing a huge amount of winter warming in Illinois.

The map is fairly precise, and 100% fraudulent at the same time. Winter temperatures in Illinois did indeed rise significantly from 1975 to 2007.

But the long term trend is down. They intentionally cherry picked A thirty year warming period, in order to defraud their visitors into believing that a non-existent warming phenomenon is happening in Illinois.

Illinois has been having very cold winters, with record amounts of ice on the Great Lakes.
Ice coverage on the Great Lakes reached 85.4 percent on Feb. 18, marking the second winter in a row that ice coverage has exceeded 80 percent. This figure has fluctuated up and down slightly since then and was at 88.8 percent as of Feb. 28. Of course, last year the Great Lakes went on to record their second highest total ice coverage in records dating to 1973.

The NCAR claim is flat out fraud, with no scientific value – and specifically intended to mislead their visitors.
