Changing History Is Easier Than Changing Facts - Verse 2

SEARCH BLOG: CLIMATE CHANGE

Anthony Watts published the following two charts on May 2. The first chart shows the period between 1980 and 1998 as rough at the long-term U.S. average and cooler than the 1930s. Then the data was reworked to show the same period at roughly 0.5° above the long-term average... ending slightly higher than the 1930s.

ICECAP had mentioned something similar without the graphics. In the ICECAP story, "The two revisions of the IPCC surface record each successively lowered temperatures in the 1950s and the 1960s. The result? Obviously more warming – from largely the same data."

First we have weather monitoring equipment that is biased toward warmer readings because they are poorly located. Then we have have those biased readings adjusted upward?
Playing fast and loose with data... whether lowering historical temperatures or raising more recent ones... is not only intellectually dishonest, it is perpetuating a massive fraud on the world... one that will cost trillions of dollars.
But there are some federal government present and former employees who are benefiting from these adjustments... with one even writing the praises of the other.
