Michael Mann Continues His Extreme Meanders Of Climate Fraud

There are many crooks in the climate science business, but none more brazen than Michael Mann, who is now blaming California drought and “extreme meanders” in the jet stream on global warming.

Climate change is altering global air currents – increasing droughts, heatwaves and floods

One of the scientists who demonstrated conclusively that global warming was an unnatural event with the famous “hockey stick” graph is now warning that giant jetstreams which circle the planet are being altered by climate change.

Professor Michael Mann said extreme weather events – such as the “unprecedented” drought in California last year, the flooding in Pakistan in 2010 and the heatwave in Europe in 2003 – were happening more often than they should do, even taking the warming climate into account.

I blogged yesterday about how fraudulent this claim is.

This, he said, meant there had to be an additional factor.

Jetstreams are influenced by the difference in temperatures between the Arctic and the equator.

But the Arctic has been warming much faster than tropical climates – the island of Svalbard, for example was 6.5 degrees celsius warmer last year compared to the average between 1961 and 1990. The land has also been warming faster than the sea.

Both of those factors were changing the flow of these major air currents to create “extreme meanders” which were helping to cause “extreme weather events”, Professor Mann said.

Last year, another leading climate scientist warned that the rapid rate of warming in the Arctic could have a “catastrophic” effect on the weather in the northern hemisphere.

In a paper in the journal Scientific Reports, Professor Mann and other researchers wrote that evidence of the effect of climate change on the jetstreams had “only recently emerged from the background noise of natural variability”.

This claim is just as fraudulent as everything else Mann says. Forty years ago, experts said the exact opposite. They blamed California drought and extreme meanders in the jet stream on global cooling.

the 1977 drought is judged by experts as more severe than the 1930’s.

National Geographic : 1977 Dec, Page 822

Mann reported 6.5 degrees Arctic warming as proof of his Mann made global warming theory.  But in 1947, experts reported ten degrees Arctic warming since 1900.


Global warming theory had been disproved by 1991, after 45 years of Arctic cooling and thickening Arctic ice.

Actual science and facts weren’t going to bring any money in for fraudsters like Mann and Gavin Schmidt at NASA, so they simply erased the post-1940 Arctic cooling.

Global warming is the biggest scam in science history, There is no indication that the climate is changing in any way other than natural cycles, so government funded climate scamsters alter data and then use the fake data as the basis for their junk science theories.

    Perhaps it means nothing, but it seems to me that Meridional flow seems to become more likely or at least more extreme during times of lesser solar activity. Cycle 20 which lasted through June of 1976 was a rather muted cycle with the least activity compared to cycles 19, 21, 22, and 23. Now here we are in cycle 24 with the weakest cycle anyone alive has experience and finishing up with lower activity than projected. And what do we see? Sustained Meridional flow beginning last year. One loop of Arctic air after another keeps dipping down in the temperate zone. If it’s not colder than normal in Central Asia then it has been in Europe or N. America. The loops of the jet just keep coming.

      The 1977 National Geographic article attributed the loopy jets stream to variations in sunspots.

      • RAH says:

        If Joe Bastardi is correct we here in N. America aren’t out of the woods yet.
        Both the US and European models are predicting another loop to hit next month. IOW what Europe is starting to get, we in the eastern half of the US are going to see about the same time in May.

      • Bruce of Newcastle says:

        Mike Lockwood of Reading U also says low solar activity, in context of the very cold UK winter of 2010 – which was the bottom of the last solar cycle.

        Bear in mind that Lockwood is an IPCC lead author, and not a known climate sceptic.

        That we’re again seeing meandering jet streams and blocking events, when solar activity is back down to 2010 levels, supports his position.

      Interesting links. I managed to make time to watch that hearing and was gobstruck that anyone, or any group seeking legitimacy, would put Michael Mann in front of a microphone to speak on its behalf. From everything I’ve seen of Prof Curry, she’s been composed, thoughtful, professional in her manner and presentation and displays a caution about absolute statements, that one might expect from an intellectual who understands the value of humility, or at least, recognizes the disastrous trap of hubris. In saying this, I shouldn’t omit either Profs Pielk or Christy, both of whom were similarly professional, respectful (even graceful) in stark contrast to the red-faced and hyper-defensive Michael Mann. I mean…wow. M&M IS hubris, incarnate. What an embarrassing gobshite.

      Using this contrast, it also related to points made at the bottom of your second link. My mind in the past year (or so) has changed from being someone who accepted the “consensus” after I was challenged to look deeper. What I’ve discovered since has left me stunned…and angry; a feeling of being ill-used for good faith. But, not only the content of the message matters (though that matters a lot!). The means by which it’s conveyed either demonstrates character and trustability, or it doesn’t. Character makes people more open to listening to you, even if they think they will disagree with what you have to say, they will at least consider that the source being listened to isn’t an ass and may have something for them consider. Profs Curry, Christy and Pielke demonstrated character, while M&M sounded like an ass. And that, in the long run, matters.

    Trump and Pruitt have got to drain this Mann critter from the swamp,
    even tho he is not in Washington.
    It seems impossible that Penn State continues to support this fraud.

    • RAH says:

      Money talks. Mann is a “distinguished Professor” at Penn State because he has brought far more money to the school that he has cost them. It is that financial backing which also makes it possible for him to file and follow through on lawsuits. Better perhaps to discredit Mann and at the same time put the real effort into cutting off any government funding for him and those like him. Then file multiple suits against them and watch them wither on the vine. Take their funding away and their careers will end.
