Glikson: descends to pseudo-psychology and projection?

Dr Andrew Glikson

Remember the Great Debate between myself and Dr Andrew Glikson? He’s back – in Climate change denial: The misrepresentation of climate science he calls names, resorts to inventing a mental illness, creates strawmen whom he beats down mercilessly, all the while misrepresenting thousands of scientists who disagree with him, and making statements that can be proven false with a few seconds of Googling.

We are most fortunate that Brice Bosnich managed to pop in and report on what Glikson had to say (below). I wish I could have been there to hear Brice ask those questions….

Glikson knows the main Skeptic arguments, so why did he ignore them?

In the Great Debate of May 2010, Andrew Glikson and I exchanged replies in a five part series that took six weeks and amounted to over 17,000 words, 26 graphs, and dozens of references. It’s the only long serious climate debate in writing that I’m aware of. He was unable to provide convincing empirical evidence to back up his claims of impending catastrophe. He asked if he could respond […]

The deep oceans drive the atmosphere

Ever wondered how the whole planet could suddenly “get warmer” during an El Nino, and then suddenly cool again? William Kininmonth has the answer. As I read his words I’m picturing a major pool of stored “coldness” (bear with me, I know cold is just a lack of heat) which is periodically unleashed on the surface temperatures. The vast deep ocean abyss is filled with salty and near freezing water. In years where this colder pool is kept in place we have El Ninos, and on years when the colder water rises and mixes up near the surface we have La Ninas. The satellites recording temperatures at the surface of the ocean are picking up the warmth (or lack of) on this top-most layer. That’s why it can be bitterly cold for land thermometers but at the same time the satellites are recording a higher world average temperature, due to the massive area of the Pacific.

In other words, just as you’d expect, the actual temperature of the whole planetary mass is not rising and falling within months, instead, at times the oceans swallow the heat on the surface and give up some “coldness”. At other times, the cold […]

Round Five: Ignore the main point, repeat the irrelevant

The debate with Paleoclimatologist Dr Andrew Glikson about the evidence for Climate change has reached a telling point. There is a gaping hole.

Through four rounds of to and fro, I’ve been asking for evidence that the predicted (critical) “hot spot” was there above the equator, and we were drilling down to this point. It’s the weak link in the chain of evidence, and if the climate models are wrong on this element, you can kiss goodbye to the catastrophe. Everything else might be right, but there’s no major warming if there’s no strong amplifying (positive) feedback, and and there is no amplifying feedback from water vapor if there is no hot spot. Indeed, I quoted evidence from three peer reviewed studies that show that we’re headed for a half a measly degree of warming rather than a baking 3 – 6 degrees.

In Round 2 Glikson didn’t mention Lindzen, Spencer or Douglass (the three independent papers which suggest that predicted feedbacks are missing or negative). Instead he suggested “Sherwood 2008” found the hot-spot. I pointed out that Sherwood used wind-gauges instead of thermometers. To believe he is right we need to throw out thousands of thermometer readings and […]

Debate part 5: The planetary atmosphere and climate change

Round 5 of my debate with Andrew Glikson Dr Andrew Glikson and I have been debating the evidence first through Quadrant, and then here. Kudos to him for following this up in a polite, diligent manner. This kind of open debate is extremely rare, and I am happy to encourage it. I will post a reply in a few days. For the moment I think the many able commenters here can discuss its merits. The only thing I’ll say now is that in each of my four previous replies I ask for evidence that the models are right on the magnitude of the feedbacks. Is it half a degree or 3.5oC? Part I: AG / JN; Part II: AG / JN; Part III: AG / Part III & IV: JN (& AG). (Part IV took place in the comments below Part III). Yes, this is the first time I’ve had a guest post from a scientist who disagrees… My reply is here. — Jo

Great Debate Part III & IV – Glikson accidentally vindicates the skeptics!

UPDATED Part IV: Andrew Glikson replies below.

I am impressed that Glikson replied politely, rose above any ad hominem or authority based arguments, and focused on the science and the evidence. This kind of exchange is exceedingly rare, and it made it well worth continuing. Links to Part I and II are at the end. Round 4 was copied from comments up to the post.

Depending on flawed models

by Joanne Nova

May 11, 2010

For a sentence, I almost think Dr Glikson gets it. Yes, it’s a quantitative question: Will we warm by half a measly degree or 3.5 degrees? It’s not about the direct CO2 effect (all of one paltry degree by itself), it’s the feedbacks—the humidity, clouds, lapse rates and other factors that amplify (or not) the initial minor effect of carbon.

Decades ago, the catastrophe-crowd made guesses about the feedbacks—but they were wrong. Instead of amplifying carbon’s effect two-fold (or more!) the feedbacks dampen it.

Dr Glikson has no reply. He makes no comment at all about Lindzen [1], Spencer[2] or Douglass[3] and their three peer reviewed, independent, empirical papers showing that the climate models are exaggerating the warming by […]

The debate continues: Dr Glikson v Joanne Nova

Dr Andrew Glikson (an Earth and paleoclimate scientist, at the Australian National University) contacted Quadrant offering to write about the evidence for man-made global warming. Quadrant approached me asking for my response. Dr Glikson replied to my reply, and I replied again to him (copied below). No money exchanged hands, but Dr Glikson is, I presume, writing in an employed capacity, while I write pro bono. Why is it that the unpaid self taught commentator needs to point out the evidence he doesn’t seem to be aware of? Why does a PhD need to be reminded of basic scientific principles (like, don’t argue from authority). Such is the vacuum of funding for other theories that a debate that ought to happen inside the university obviously hasn’t occurred. Such is the decrepit, anaemic state of university science that even a doctorate doesn’t guarantee a scientist can reason. Where is the rigor in the training, and the discipline in the analysis?

Credibility lies on evidence

Reply to Andrew Glikson

Dr Andrew Glikson still misses the point, and backs his arguments with weak evidence and logical errors. Instead of empirical evidence, often […]

No, Dr Glikson

Dr Andrew Glikson writes for Quadrant and I respond .

This is a copy. It begs the question. Dr Glikson, is an Earth and paleo-climate scientist at the Australian National University. He’s paid to give us both sides of the story.

No, Dr Glikson

Dr Andrew Glikson says the right motherhood lines [see: Case for Climate Change]: he talks about empirical evidence, and wants evidence based policies. All this is good, yet he sidesteps the main point — what exactly is the evidence for the theory of man-made global warming? It’s the only point that matters, yet when he presents evidence it’s either not empirical, not up to date, or not relevant. Why?

By hitting all the right key phrases a reader might accidentally think that Glikson is presenting key evidence and good reasoning. Take this for example: Glikson fears we’re turning away from evidence-based policies. (Me too!) But to complete the sentence he lists all the committees who predict bad weather 90 years from now. It makes for good PR, but is not scientific evidence.

Committee reports count as “evidence” in a court of law, but in science, certificates, declarations, contracts, commission […]
