Skeptic Steve Goreham gives Michael Mann a Twitter fit

“Is it a failure to communicate, or faulty climate science?” by Steve Goreham is driving Michael to distraction.

Goreham writes:

Climate science has smelled for some time. The 2001 Third Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) announced “new evidence” claiming that “the increase in temperature in the 20th century was likely to have been the largest of any century during the past 1,000 years.” This was the famous “Hockey Stick Curve” of Dr. Michael Mann, which became an icon for Climatism, trumpeted to the world and taught in schools across the globe.

But the tree-ring data used by Mann and his research team did not show a temperature rise at the end of the 20th century, so they pasted the thermometer record for the last 50 years onto the 1,000-year curve to provide the alarming hockey stick temperature rise. Later analysis by Stephen McIntyre and Dr. Ross McKitrick found that the Mann algorithm would also produce a hockey stick from input of random noise. The IPCC dropped the Mann Curve from their 2007 Fourth Assessment Report without any explanation.

  1. dana1981 – you ever have a talk with your single mother about how her unhealthy need for female child screwed up the development of her male offspring, particularly with regard to naming said child?
