Global warming was the GOAL of the research and to find any evidence otherwise is regarded as failure.
The rinky-dink computer models they use will come with anything they need if they "tweak" them enough....and they do...for $$$$.
News of everything that proves global warming is not man-made is suppressed. Same $$$ at work.
Even global warming's biggest believers will have to admit, that the difference between us taking drastic measures and doing absolutely nothing would only make the difference (in their own computer models, (fully tweaked) of a fraction of one degree over a hundred year span.
It's the "herd instinct" that makes most people buy into it. They are told a huge number of scientists favor global warming. Science has never been about choosing up sides and which ever side has the most members must be right. That's not science, it's political spin.
If you still believe in that crap, you haven't really done any homework. It's all available online and is easy to find. There's no good excuse for being "Stuck on Stupid" on this subject.
Hockey Sticks, Principal Components and Spurious Significance
This article identifies what is almost certainly a computer programming error in the principal components method used in MBH98. The error causes their PC method to nearly always identify hockey stick shaped series as the “dominant pattern” in a data set (the so-called “first Principal Component” or PC1), even when the data are just random numbers. We carried out 10,000 simulations in which we fed “red noise”, a form of trendless random numbers, into the MBH98 algorithm and, in over 99% of the cases, it produced hockey stick shaped PC1 series.
