The debate's over folks.
Back when the "climate researcher" folks had their lab hacked into and their data set and source code stolen I wrote an article on what was in there -- including obvious adjustments in the FORTRAN code that were one way.
Post that incident there was a "convenient" loss of original data -- which made re-examination on an objective basis of much of the so-called "work" impossible.
Unfortunately for the screamers, they didn't get all of the data sets. There were plenty of them left, and eventually some folks took to actual mathematical analysis of them.
You can read their conclusions here -- but let me just quote a bit of it.
The conclusive findings of this research are that the three GAST data sets are not a valid representation of reality. In fact, the magnitude of their historical data adjustments, that removed their cyclical temperature patterns, are totally inconsistent with published and credible U.S. and other temperature data. Thus, it is impossible to conclude from the three published GAST data sets that recent years have been the warmest ever –despite current claims of record setting warming.
Finally, since GAST data set validity is a necessary condition for EPA’s GHG/CO2 Endangerment Finding, it too is invalidated by these research findings.
In other words, and to expand:
1. No, it has not been the "warmest ever."
2. There were more severe "heat wave" incidents in the 1930s, in point of fact, there was a cold period in the 1960s and 70s (which some of us who are old enough remember!) and today's anomalies are approximately equal to that of the early 1990s.
3. These facts including both the hot and cool periods earlier in the 19xx years, fit not only across the United States but globally in the Northern Hemisphere.
It is therefore quite-clear that the data has been intentionally tampered with.
Since this has formed the basis for plans to steal literal trillions of dollars and has already resulted in the forced extraction of hundreds of billions in aggregate for motorists and industry this quite-clearly constitutes the largest economic fraud ever perpetrated in the world.
I call for the indictment and prosecution of every person and organization involved, asset-stripping all of them to their literal underwear.
