In 2000, USHCN apparently wasn’t happy with the fact that the 1930s was the warmest decade – so they gave the past a demotion and bumped the 1990s way up.
Apparently that wasn’t enough though. An astute reader (Steve Case) captured the USHCN data in 2008 and again today. Below is a plot of the further adjustments during the last two years. Once again, the present has been artificially made warmer and the past has been made cooler. Temperatures in 2007 were raised by 0.16 degrees, and temperatures were lowered by 0.08 degrees in 1930.
Suppose a company wasn’t happy with their financial reports, so they subtracted money from past earnings and added them to present earnings. What would happen to the people in charge?
