Friday Funny: Will the World Drown as Greenland Ice Melts? (w/ Dr. Michael Mann)

From the “Manntastic claims require Manntastic evidence” department.

From the description:

The human eye could see the rise in sea level as the ice sheets in Greenland melt. Measurements also show a change in gravity as the ice melts. A new study has climate models showing the variation in ice sheet melts and how sea levels will rise so much, that low land across the globe is at risk.

Dr. Michael Mann joined Thom [Hartmann] to discuss how serious the rate of melt in Greenland and the evidence that the planet is in danger.

You’ll need a barf bag to watch.

h/t to CTM, who is recovering from surgery. We wish him the best.

I guess that Dr Mann hasn’t kept up on the literature. My peer reviewed manuscript in the September
issue of the journal Dynamics of Atmospheres and Oceans mathematically proves that all current
global climate models are based on the wrong atmospheric dynamical system of equations and therefore cannot be relied on too produce any meaningful results. I repost my previous comment.

The only way any results from a climate model could be trusted are:

The continuum errors in both the dynamical and physical equations approximated by the model are smaller than the truncation errors of an accurate (almost convergent) numerical solution.

Now let us discuss each of these requirements in detail.

1. All current global climate models are approximating the wrong dynamical system (the hydrostatic system) of equations. This has been mathematically proved in my peer reviewed manuscript that appears in the September issue of the journal Dynamics of Atmospheres and Oceans and in another thread on this site (Structural Errors in Global Climate Models).

2. The physical equations are approximated by discontinuous parameterizations that have large continuum errors and that violate the necessary requirements that the continuum solution be expandable into a Tayor series. The necessary unrealistically large
dissipation needed to prevent the model from blowing up due to these discontinuities leads to a large continuum error and destroys the numerical accuracy as shown by the Browning, Hack, and Swarztrauber cited in the above manuscript.

3. As the requirements for a numerical method to converge to an accurate approximation of the continuum equations are violated,
the numerical solution will never be close to the true solution.

Thanks, Jerry, fascinating stuff as usual. One small point. You say:

3. As the requirements for a numerical method to converge to an accurate approximation of the continuum equations are violated, the numerical solution will never be close to the true solution.

As my dad used to say, “Even a blind hog will find an acorn once in a while.” I would say:

“.. the numerical solution will only accidentally ever be close to the true solution.”


(As a kid I thought my dad said “Even a blind hawk will find an acorn once in a while.” As a result, I spent a good chunk of my youth puzzled as to why a hawk would want to find an acorn, and what it would do if it did.)

I had to wait 18 years to publish the manuscript until the “scientists” that kept gate keeping our manuscripts either retired or died. I was fortunate to find an Editor who is objective and honest and has no vested interests in climate modeling. The reviewers were open minded enough to see that the mathematical arguments are sound even though they prove that there have been major logical errors in the atmospheric sciences.

The IPCC can no longer making any claims based on climate models and if so, anyone can just point to the manuscript and have them state how they can obtain the “right” answer
when they have violated the basic principles of the Bounded Derivative Theory (BDT) and numerical analysis.

My only regret is that Heinz is not alive to be a coauthor on the manuscript given that the BDT he introduced was developed to resolve the mathematical issues with the hydrostatic
system used in all current global climate and weather models.

Hockey Puck does not seem to understand simple things like there is no US climate – climate is worldwide. The US does not control worldwide CO2 – China, India, Indonesia, and many other countries control CO2 emissions. And, Hockey Puck, your cure is far worse than the alleged disease.

Never fear. The sea will not rise around the houses of the climate-savers. Surely, what Moses accomplished, Obama must be able to do also. There will be vertical walls of water, which will of course make the sea rise even more where the climate-wreckers live. This is climate justice, aye. By the time our emissions have caused all the ice to melt, Obama’s home will be surrounded by a waterwall hundreds of feet high. Grateful whales will lovingly look down on his roof terrace. Penguins will swim all the way from the Antarctic to shower him with votive gifts, small dead fish that they have caught all by themselves. Polar bears will come and offer their furs as rugs and doormats, with not even an envious glance at his icecube-machine. And sunshading will not be an issue anymore.

NOAA documents that global SLR has been in a LINEAR trend of 3.0 +/- 0.4 mm/year since 1993, based on satellite altimetry data from the TOPEX, Jason-1, Jason-2 and Jason-3 satellites.

As you allude to, Mann’s absurd claim would require a 8-10 times higher rate of SLR if linearized over the next 80 years. Ain’t gonna happen . . . but then again, Mann won’t be around to apologize.

Mann: “The human eye could see the rise in sea level as the ice sheets in Greenland melt.”

In certain areas of the coast, particularly during the new or full moon, sea level can rise or fall by 2 meters or more in 6 hours between high and low tide (a rate of about 5.6 mm per minute). On top of that, how is anyone supposed to notice with the naked eye a sea level rise rate of 2 millimeters per year (about 3.8 * 10^-6 mm per minute)?

The problem with using changes in gravity to measure changes in ice amounts, is that ice isn’t the only thing that changes. Isostatic rebound influences gravity. Magma moves around, influencing gravity.

They claim that they are adjusting for such factors. However, as I have always said, when your changes are larger, much less 10 times larger, than the signal you claim to have found, then you haven’t really found anything.

The weight I gained over the ‘rona house arrest increased my gravitational field – which increased the pull between my mass and the moon.

Micky Mann is a pathological liar. And one of his many ways of lying, a favorite of many of his ilk, is to use a meaningless factoid, which on the surface, sounds good, but is actually pure junk science meant to persuade, mainly by using fear. Take for example, his factoid about the amount of ice melting in July two summers ago. Anyone with half a brain could quickly figure out that if you wanted to pick a month to showcase melting ice, you probably couldn’t do much better than July. He then uses a trick, another form of lying, using a red herring: that the amount of ice which melted (and we’ll assume the amount is true, although with PantsonFire, you never know) would raise SL by 1/2 cm, or about 3/16 inch. And yes, of course the human eye can see 3/16 inch. But so what? How much of that icemelt actually wound up in the ocean? I would wager that much of it stayed in place, and simply re-froze. And when ice rebuilds in colder months, there are likely times when the amount of ice forming during that month would equal that which melted that July. Using his idiotic red herring, we could also see that 3/16 inch subsequent drop in SL.

Worse is – as I always point out – that the ice is displacing its own mass in magma… so the tectonic and volcanic repercussions of the Greenland melt could be more catastrophic than a simple small sea level rise.

As the ice melts and drains out, the rock below will start rising up causing magma under the surrounding ocean to flow in the direction of Greenland to fill the suction beneath it.

While that might be compliment to the climate priesthood where catastrophic man-made climate change is now a faith-based religion, it is a slamming rebuke to someone who is supposed to be a scientist. When scientists turn to public advocacy, as the AAAS and NAS now pushes for, it means we end up with politicized science and scientists. Those scientists then are unable to self-correct when faced with glaring inconsistencies in observation versus claims. So the push ever onward spewing ever bigger whoppers like this one from Monsignor Mann.

October 2, 2020 4:05 pm

Stopped listening at “half a centimeter of sea level rise from Greenland ice melt in one month”. It would be disastrous if it were true, but it isn’t. Do the math (which Mann apparently can’t).

Say 3 months a year of that kind of ice melt, so 15mm or more of sea level rise per year. That’s 5 TIMES the rate of sea level rise measured by satellite (3.1 mm/yr). Even if it was only 1 month per year, that’s almost double the annual rate of sea level rise. Back to reality. Several studies estimate annual sea level rise from BOTH Greenland and Antarctica at 0.5 to 0.9 mm PER YEAR, which is…wait for it…one fifth to one tenth the amount that Mann claims from Greenland alone for one month.

I guess when you get tenure, your brain stops working.

!2,000 years ago the Bering Sea was frozen over. It also melted. Did the American Indians, who crossed from Asia, cause that?
Now I know why Trump offered to buy Greenland from the Danes. I’m voting for Trump.

So … Mann controls the weather (or at least the narrative).
Yet he, like Hansen, have been so wrong about what they said should have already happened but didn’t.
Mann seems to have a history of claiming a current condition (with a few Storm Channel-ish exaggerations) is just what he said would happen (absent the time and severity and sometimes even the event).

I am a snoop about what books people keep handy on their shelves. Besides Mann’s copy of the Hockey Stick and Climate Wars, there is some special set of Feynman’s Lectures on Physics that includes Feynman’s Tips on Physics — looks to be unopened.

Based on Michael’s comment i just wonder if he ever been to the arctic for any period of time in the summer or winter. I have previously spent a reasonable amount of time in the Canadian arctic islands years ago on geological field parties and also on drilling sites. the climate change that may be happening in the last few years may not be unusual over a longer period of time. go up there and try it in the winter or summer. be prepared for some unusual weather. good luck.

How can anyone take Mann seriously when he has been exposed as a total fraudster?

And a joke and a clown, with his home made fake Nobel Prize.

Apologies If someone made this comment above. I have not read them all. BUT, why is Greenland called Greenland? Because when the Vikings from Norway settled there, the land was not covered in ice and they were able to grow crops – green crops. Hence Greenland!
Professor Mann thinks nothing like this happened, which is why he wanted to lose the Medieval Warming Period to validate his hockey stick theory. I put the point to Sir John Houghton, former chief scientist in the UK, and he said that was just local, not global. I think not…

I thought they called it Greenland because it was covered in ice, where as Iceland was not and it was a ruse to throw off anyone from trying to conquer the new found farm lands?

Maybe just a funny story, but I could see the Vikings doing that, they were well traveled and conquerors themselves.

I remember in elementary school in the 50s we were told they were confused about island which was which and misnamed them.

It was actually called Greenland as a PR exercise by Eirik the Red who discovered the place in 986.

Source: Islendingabok written c. 1125 by Are Frode (incidentally the second oldest book ever written in a Scandinavian language, the oldest being the Icelandic law code Grágás from 1121).

I will not put the electrons of my new monitor through the torture of playing a video in which a PhD seriously just labeled TIDES as watching the sea level rise with his own eyes. Did he not see it fall as well?


The man is a joke. A total joke. To coin an old favorite of my mother’s, “he can’t find his way out of a wet paper bag with a knife”.

This fraudulent hoaxter should be in State Pen. There is no sea level rise. His climate models are bull[snip], and he has absolutely no authority on sea level science. He is as informed as Joe Biden, Barack Obama and Al Gore.
