One of the iconic “proofs” of man-made global warming is the infamous “hockey stick” graph”.

“Hockey Stick” graph.

Skeptics questioned the statistics and data used to generate the graph.  So, as Powerline’s John Hinderaker noted, “a group of climate alarmists headed by Shaun Marcott, a geologist at Oregon State, released a study that purported to resurrect the infamous hockey stick.”

Their article recently appeared in Science, and was then republished by the usual elite media global warming perpetrators.

This second graph just got fisked, big-time.

Anthony Watts, on his Watts Up With That blog, summarizes the work of climate-science watchdog and data analyst extraordinaire, Steve McIntyre.  McIntyre figured out how the “hockey stick” scientists “hid the decline“.

It seems the uptick in the 20th century is not real, being nothing more than an artifact of shoddy procedures where the dates on the proxy samples were changed for some strange reason.

What was the nature of the change? Scientist Lorraine Yapps Cohen explains in her Examiner piece:

McIntyre’s analysis of the data is too complicated to go into here. Suffice it to say that he examined how Marcott’s data was “recalibrated,” “redated,” and otherwise manipulated to produce the desired result as a dramatic rise in recent global temperatures. Perhaps worst of all, data that showed the embarrassing decreasing temperatures in the 20th century were simply…. dropped.

Yes, dropping data tends to impact final results.

Yapps Cohen reports that there are many calls to Science to retract the “hockey stick” paper. However, David Rose of the UK Daily Mail offers proof that even if the magazine fails to do so, the hot-air is already leaking from the Global Warming balloon.

The Mail on Sunday today presents irrefutable evidence that official predictions of global climate warming have been catastrophically flawed.

The graph on this page blows apart the ‘scientific basis’ for Britain reshaping its entire economy and spending billions in taxes and subsidies in order to cut emissions of greenhouse gases. These moves have already added £100 a year to household energy bills….

The graph shows in incontrovertible detail how the speed of global warming has been massively overestimated. Yet those forecasts have had a ruinous impact on the bills we pay, from heating to car fuel to huge sums paid by councils to reduce carbon emissions.

The two graphs paint a grim picture of climatology as it is practiced today. As Hinderaker concluded:

In short, the global warming movement is corrupt to the core. Billions of dollars in government funding–I am too polite to say “bribes”–have bought not just the acquiescence but the eager collaboration of many scientists in a massive fraud.
