The great global warming scam (ctd)


from Spectator.uk:
A small ‘but closely knit’ number of scientists all used the misleading Yamal data to claim that today’s temperatures were unprecedentedly hot. Orlowski notes:

Controversy has been raging since 1995, when an explosive paper by Keith Briffa at the Climate Research Unit at the University of East Anglia asserted that that the medieval warm period was actually really cold, and recent warming is unusually warm. Both archaeology and the historical accounts, Briffa was declaring, were bunk. Briffa relied on just three cores from Siberia to demonstrate this.

Three years later Nature published a paper by Mann, Bradley and Hughes based on temperature reconstructions which showed something similar: warmer now, cooler then. With Briffa and Mann as chapter editors of the UN's Intergovernmental Panel on Climate Change (IPCC), this distinctive pattern became emblematic - the ‘Logo of Global Warming’.

But as the heroic mathematician Steve McIntyre – who helped demonstrate the fraudulence of the even more seminal AGW claim of the ‘hockey-stick curve’ of historic global temperatures – has finally managed to winkle out, their premise was false and their claim was untrue.
