How Fraudsters Turn the 24th Warmest October Into the 4th Warmest

The animation below, via Real Science, shows how NCDC turned the 24th warmest October, into the 4th warmest October.

Writes RS:

The actual thermometer data showed October as the 24th warmest, nearly four degrees cooler than 1947 and 1963, and on a long term cooling trend.

After time of observation bias adjustments, the past has cooled, but temperatures are still on a downwards trend.

The biggest cheat comes when they apply the UHI adjustment and homogenization, which makes the past much colder (yes, you read that correctly) and turns a cooling  trend into a warming trend.

Finally NCDC throws in an additional cheat, on top of the USHCN cheats.
