There are three main global temperature datasets. One is at the CRU, Climate Research Unit of the University of East Anglia, where we’ve been trying to get access to the raw numbers. One is at NOAA/GHCN, the Global Historical Climate Network. The final one is at NASA/GISS, the Goddard Institute for Space Studies. The three groups take raw data, and they “homogenize” it to remove things like when a station was moved to a warmer location and there’s a 2C jump in the temperature. The three global temperature records are usually called CRU, GISS, and GHCN. Both GISS and CRU, however, get almost all of their raw data from GHCN. All three produce very similar global historical temperature records from the raw data.
Yikes again, double yikes! What on earth justifies that adjustment? How can they do that? We have five different records covering Darwin from 1941 on. They all agree almost exactly. Why adjust them at all? They’ve just added a huge artificial totally imaginary trend to the last half of the raw data! Now it looks like the IPCC diagram in Figure 1, all right … but a six degree per century trend? And in the shape of a regular stepped pyramid climbing to heaven? What’s up with that?Indeed. What kind of scientist would do such nonsense? Perfectly good taxpayer's earnings are being used to pay these jokers. Then these jokers provide the EPA with the ammunition to shoot us through and through with a ruling that the very act of human breathing is polluting the atmosphere with CO2 emissions! What is the common cause that unites the NASA GISS, NOAA GHCN, the CRU of East Anglia University, our EPA, and the UN IPCC? I believe it is an international and national power grab by socialists and man-hating environmentalists.
