Andy Dessler’s Bloopers

Andrew Dessler

I looked at Andy Dessler’s claims that monsoon floods in India are connected to climate change in an earlier post today.


Andy’s track record for climate pronouncements sadly leaves a lot to be desired!


I first came across him in 2012, shortly after starting this blog. The year before he wrote in the Houston Chronicle:

As you sit by the pool and sweat this summer, one book you should be reading is The Impact of Global Warming on Texas (University of Texas Press, June 2011, second edition). This book, written by a group of Texas academics, is a sober analysis of our state’s vulnerability to climate change — and the things we can do about it.

It is a particularly appropriate read as we suffer through the hellish summer of 2011. While it is unknown exactly how much human activities are contributing to this summer’s unpleasant weather, one lesson from the book is clear: Get used to it. The weather of the 21st century will be very much like the hot and dry weather of 2011. Giving extra credibility to this forecast is the fact that the weather extremes that we are presently experiencing were predicted in the first edition in 1995.


Well, that prediction did not work out very well, did it Andy?





Being so badly wrong about something he should have known about did not stop our Andy from spouting more nonsense about things he knew nothing about:




The Guardian are of course more than happy to publish any nonsense they have been given by the likes of Mann and Dessler. Even though it bears no resemblance to the actual data:


But for Andy, facts are a bit irrelevant. It is politics that matter most:




That was back in 2008, but he is still pushing his far left agenda today, judging by his Twitter feed:







With a track record like that, it is little wonder that Roger Pielke Sr had this to say about Dessler, Mann and Elsner in 2015:

    Well, of course it was hot in Texas in the summer. Perhaps he should have gone to the June-August data for Al Gore’s home state of Tennessee, or Kentucky, even Indiana? Cherry-picking is always misleading. And especially so from NOAA who keeps lowering the older data from the US Weather Bureau.

    He has lots of practice being wrong.
    He’s a pro at it now.

      I really had to think hard about the use of the (short-form) word, ‘pro’ in your comment. I was torn between ‘professional’ and ‘prostitute’. The latter seemed a better fit.

    You really think he would be embarrassed or worried that he gets proved wrong? As far as he and his ilk are concerned he’s doing an excellent job getting the propaganda headlines out to the masses.

    “While it is unknown exactly how much human activities are contributing to this summer’s unpleasant weather, one lesson from the book is clear: Get used to it”

    Translation: we have no evidence that AGW has anything to do with this summer’s unpleasant weather but let’s pretend that it does. That’s the science of it anyway what with the 97% consensus and all.

      With the weasel word “exactly” in there to make it sound as if they sort if know, when in fact the it is simply unknown.

      But then he starts using attribution “science” so that he can claim he does know. He’s a fraud using fraudulent science to make false claims.

    So Bogus. They make any claim and then tell you to prove they are wrong.

      Yes sir. This is indeed what they do. It’s what all proponents of failed theories do. It is called “Shifting the burden of proof fallacy”

        Wow! I think this is the best post I’ve seen dealing with climate activism, thank you Chaamjamal. ( used to have use of a holiday home in Hua Hin, near Cha Am.

        Chaamjamal. Very well said.

        Yet the link, although good, did not refute the claimed acceleration of SL rise, whereas tide gauges do refute that claim.

    Interesting. You headed for California or Texas Dave? Might be a better climate further north.

    For the first time, this morning’s weather forecast on R4 used the phrase ‘global heating’ as a way to describe the reason for the hot weather the UK is currently enjoying. Me? I call it August.

      It is certainly staying quite warm in the evenings at the moment even out in the country. Looking forward to some refreshing thunderstorms.

        The showers won’t be that refreshing, they will just send humidity sky high, the temperature will stay the same. In fact the heat will spread further up the country….. until Thursday/Friday when it will get proper refreshing.

        Thankfully the wind has enough of a S component today to come off the sea so 26/27C feels ‘cool’ today on the S.Coast, sadly Tue/Wed get hotter again.

        After all the BBC ‘global heating’ causing ‘tropical nights’ line, I think most places have actually just dipped below 20C most nights – even Heathrow.

        Mr GN: Yes, had to laugh at the BBC’s idea of UK ‘tropical nights’. I once lived in NC and holidayed on the Atlantic beach in SC. One night, listening to the 11:00pm news we were told the current temp was 90F and humidity was 95%!! BBC? Rubbish!

        Ditto here in Burgundy. None forecast before Friday. According to the locals this is the warmest spell since 2003. Note the word “since”. Maize crop is looking iffy which will be bad news round here!

      Their northern hemispheric bias is showing.

    It is said that you are known by the friends that you keep and being up there with an infamous MANNipulator of data is not good for one’s credibility. His outpourings in a lot of ways mirror those of Mann because constantly Mann spouts on subjects beyond the remit of his shaky (non)science.
    It is telling in the post Enlightenment Apocalyptic world we now inhabit that the fate Mann suffered for the shocking hockeystick fraud masquerading as scientific endeavour was to be promoted to Professor!

  10. August 10, 2020 9:52 am

    Paul, I think you are way to kind to him calling his outpourings “Bloopers”. Bloopers suggest honest mistakes. Professionally he is not allowed that margin because he should know better and if he does not then he is clearly incompetent. He is making political statements for which he needs to be called out just like his home the great MANNipulator.

    The ludicrous praise for Chinese climate policy always exposes the real political motivation behind people like Mr Dessler
