Bull. That's the crap liberals use for everything - too "complex" for mere mortals. Yeah, right. Maybe it's not too "complex" for most people, just too complex for "can't do math" journalists.
Actually the climate skeptics have made the fake science of global warming very understandable. I know a fake hockey stick graph when I see one...
By the way Mann’s fake graph welded together proxie temperature reading to actual temperature readings. IOW tree ring data up until 1980 is welded onto real world temperature readings.
Why?
To hide the decline and very ineptly.

Mann has recently claimed that the available proxy data ended in 1980, but even his co-conspirators at RealClimate admit that’s nonsense. The truth is that the proxy data was scrapped because unlike those measured, reconstructed temperatures showed a marked decline after 1980. And as the chart plotted temperature anomalies against what the plotters selected as the “normal” period and temperatures of 1961 to 1990, the reconstruction would have been quite unremarkable otherwise. So at the 1980 mark, the actual post-1980 measurements were attached to the truncated proxy series to create the illusion that they were one.
