Hockey Stick

Michael Mann used tricks to remove past warm periods and dupe rubes into thinking this is the warmest period in history.

Michael Mann used tricks to remove past warm periods and dupe rubes into thinking this is the warmest period in history. But others debunked it by showing how, and putting various data through is solution, and always coming up with a hockey stick.

Facts[edit | edit source]

In 1998 by Michael E. Mann and some colleagues used various tricks to take out past warm periods and defraud the gullible into thinking this is the warmest period in recent history.

You could put just about any data into his "algorithm" and it would come out looking like a hockey stick.

Since it made it appear like the Earth was getting lots warmer than at any time in the past (and reaching a "tipping point"), propagandists like the IPCC and Al Gore used this to scare-monger around 2000.

It was thoroughly debunked by many folks (including real Scientist Tim Ball).

Michael Mann sued Ball for defamation (the crime of telling the truth). But even in the hyper-liberal courts of Canada, Mann lost and had to pay court fees, because he wouldn't show his data like he was a real scientist.

Even the far left and completely partisan IPCC pulled Mann's Hockey-stick from subsequent reports, because it made them look bad.

Some FakeNews / Fake Fact Checkers try to pretend it's still good science. But nobody that puts science above leftist politics will agree.

Parts of the fraud[edit | edit source]

Different Measurements - One of the many flaws of Mann is they shifted between direct measurements and different temperature proxies, then put in their own fudge factors.
- Temperature proxies like icecores or tree rings, do a low pass filtering and averaging function (de-noising), which takes out spikes and anomolies. And the authors of both studies (tree rings and ice cores) warned NOT to use them to predict actual temps, exactly as Mann did.
- If you think different proxies might have different artifacts, then you're smarter than Mann and/or his defenders.

Tree Ring Proxies - They idiotically overweighted tree ring data to mislead people. And not all tree ring data, but one in particular (Bristlecone pines), despite the author of the tree-ring research warning specifically that this was more indicative of precipitation than climate and NOT to use it as a Climate Proxy which is exactly what Mann did. The Mann Hockeystick smoothed out the the historical climate spikes and valleys, by mixing in historical droughts. But people that never read deeper than the headlines, don't realize how bad that piece of "science" was.

IPCC stopped using it - The IPPC dropped using Mann in their reports because it was too bad of science, even for them. And that says a lot.

Steven Goddard showed they doctored the data - This was has never been convincingly refuted... they just did new versions so that only the old version were "debunked"... yet they used the same doctored data. ^[1]
