Washington Times: Climate due to water cycle not carbon dioxide

I’m very glad to see this point being made in the mainstream media. Earth is a water planet (yet the models don’t do clouds, rain, snow or humidity well). This is pitched for The Washington Times audience, not a science blog, but it’s a point well made, and it’s good to see the point about positive feedback from water vapor, which I (and David Evans) have been making for so long, is getting out to the mainstream press. Readers will also find the North Atlantic hurricane statistics on predictions versus outcome rather stark. – Jo

Climate change is dominated by the water cycle, not carbon dioxide

By Steve Goreham

Originally published in The Washington Times

Climate scientists are obsessed with carbon dioxide. The newly released Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) claims that “radiative forcing” from human-emitted CO2 is the leading driver of climate change. Carbon dioxide is blamed for everything from causing more droughts, floods, and hurricanes, to endangering polar bears and acidifying the oceans. But Earth’s climate is dominated by water, not carbon dioxide.

Earth’s water cycle encompasses the salt water of the oceans, the fresh water of rivers and […]

IPCC plays hot-spot hidey games in AR5 — denies 28 million weather balloons work properly

The classic hot spot prediction (A) compared to 28 million weatherballoons (B). Click to enlarge. You won’t see this in the new report.

It was a major PR failure in 2007. The IPCC won’t make the same mistake again. They’ve dumped the hot-spot graphs.

In AR4 they put in two graphs that show how badly their models really do. In the next report they plan to bury the spectacular missing-hot-spot images through “graph-trickery” and selective blindness. Each round of IPCC reports takes the spin-factor up another notch. It’s carefully crafted.

See the draft of AR5: Chapter 9: Evaluation of Climate Models

It’s hot-spot hidey games and PR tricks

In the new extra-tricky AR5 version, the IPCC “quote the critics” and ignore them at the same time. That way they can say they include the McIntyre’s, McKitrick’s, Douglass’, and Christy’s: the words are on the page, but that doesn’t mean the information is used in the conclusions. The models have failed and they bury that undeniable result under the clutter. (You’ll need to read the fine print). There is no acknowledgement that this issue of the “hot spot” drives more amplification of predicted warming in their models than any […]

Do forests drive wind and bring rain? Is there a major man-made climate driver the models miss?

Clouds over Amazon forest (Rio Negro). Image NASA Earth Observatory.

What if winds were mainly driven by changes in water vapor, and those changes occurred commonly in air over forests? Forests would be the pumps that draw in moist air from over the oceans. Rather than assuming that forests grow where the rain falls, it would be more a case of rain falling where forests grow. When water vapor condenses it reduces the air pressure, which pulls in more dense air from over the ocean.

A new paper is causing a major stir. The paper is so controversial that many reviewers and editors said it should not be published. After two years of deliberations, Atmospheric Chemistry and Physics decided it was too important not to discuss.

The physics is apparently quite convincing, the question is not whether it happens, but how strong the effect is. Climate models assume it is a small or non-existent factor. Graham Lloyd has done a good job describing both the paper and the reaction to it in The Australian.

Sheil says the key finding is that atmospheric pressure changes from moisture condensation are orders of magnitude greater than previously recognised. The paper concludes “condensation […]

Yet another paper shows the hot spot is missing

Remember the evidence is overwhelming, and deniers deny the evidence. But in Oct 2012, two atmospheric scientists were reporting, yet again, the models are wrong. Twenty years after we started looking for the fingerprint of the amplification required to make the CO2 theory of global warming work, it still isn’t there. Forgive me for harping on. It’s still The Most Major Flaw in climate models.

Never heard of “the Hot Spot”? See the first post on the hot spot argument. The models are wrong (but only by 400%!) See how climate scientists admit it’s important and missing. See how they stoop to changing color scales on graphs to pretend they’ve found it and ignore 28 million weather balloons. Or just read the summary with scientific references I wrote in May.

Background: The assumption that was wrong

Researchers made an assumption that water vapor would amplify the direct warming of extra CO2 from a small harmless amount to a large catastrophe. They started with the theory that relative humidity would stay constant in a warmer world and the thicker layer of water vapor would warm the world even more. Greenhouses gases in this instance means mainly water […]

Fasullo and Trenberth find spurious success, make headlines, but still the models crash

It’s worse than we thought — again….

Fusulo and Trenberth scored headlines around the world recently with a new paper that suggested that a few models got the relative humidity right in some tropical spots, and they also happened to be the models that predicted the hottest global outcomes.

John Christie pointed out that the models with the highest climate sensitivity are also the ones which are the worst at predicting future temperatures.

But there is more to this. It is a likely a case of twenty models predicting 40 parameters, and you can take your pick of the permutations and combinations which give one or two models a “success” here and there on one or two factors. But in the end, as Richard Courtney says, all the models are different so only one model can possibly be The Right One for the whole atmosphere, and quite likely they are all wrong.

In this case, they are still all wrong. The hot spot is still missing, and the region below it with which they scored some success is not that important.

The words hot spot and humidity over the tropics lead many commentators to think this was something to do […]

The meme spreads: Patrick Moore “gets it”

It’s interesting how the message is spreading. David and I have been arguing for 2 or 3 years that the feedbacks are the key gaping flaw, the critical point in the skeptic’s case. (And see this post last week.) It’s the amplification in the models with water vapor and clouds which is the point of highest uncertainty (and indeed it’s not just uncertain, the evidence points towards negative feedback. The models are wrong.)

Patrick Moore shared emails with David in February 2012 saying: “Yours is the best straightforward explanation of the skeptic’s rationale that I have seen, and thank-you for that.”

And now we see an interview with Patrick Moore in the Washington Times, sharing the meme:

“What most people don’t realize, partly because the media never explains it, is that there is no dispute over whether CO2 is a greenhouse gas, and all else being equal would result in a warming of the climate. The fundamental dispute is about water in the atmosphere, either in the form of water vapour (a gas) or clouds (water in liquid form). It is generally accepted that a warmer climate will result in more water evaporating from the land and sea […]

David Evans in the Fairfax press: Climate change science is a load of hot air and warmists are wrong

Today in the Sydney Morning Herald and The Age, for the first time, David Evans has been published in the Op-Ed section. Something is going on in those newsrooms…? This article, below, simply makes the point that the models amplify the direct effect of CO2 by a factor of three and that is where the most important uncertainties lie. This key factor in the debate — which we cover repeatedly on this blog– has virtually never been made before in these newspapers which are the major dailies for Australia’s two largest cities. Any debate about the effects of CO2 needs to start with the fact that most of the warming in the models comes from amplification of humidity and clouds. If the models were right about water vapor, we would have found that missing hot spot. — Jo PS: The SMH and The AGE have both closed comments already! Have they run out of electrons? Oh my? Or were they afraid the comments looked like a debate?

UPDATE: I’ve just posted that these major dailies have “disappeared” the Muller conversion article too!

Models get the core assumptions wrong– – the hot spot is missing

This is part of a series that Tony Cox and I are doing that references the most important points and papers, as a definitive resource about the evidence. The missing hotspot is not just another flaw in the theory, it proves the models are wrong: not just “unverified”, not just “uncertain”, but failed. Apologies to those who feel I harp on about this! This is a condensed review, squishing years of a scientific battleground down to it’s bare bones… — Jo

It is not well known that even the IPCC agrees that the direct effects of CO2 will only increase world temperatures by 1.2°C. All of the projections above that (3.3°C , 6°C etc) come from model projections based on assumptions of what water vapor and clouds will do (these are the feedback effects of the original 1.2°C).[i] Are the feedbacks correct?

If the IPCC models are right about the feedbacks, we would see a hot spot 10km above the tropics. The theory is that with more heat, more water will evaporate and rise, keeping relative humidity constant at all heights in the troposphere. The point has been conclusively tested with 28 million weather balloons since 1959.[ii]

 

[…]

So is the hot spot a “fingerprint” or signature? Is it unique?

Some people claim that I mislead people. But it seems they are the misled — not by me, but by their own heroes.

In the Skeptics Handbook I wrote:

“The greenhouse signature is missing If Greenhouse gases are warming the earth we are supposed to see the first signs of it in the patch of air 10 kilometers above the tropics. But this “hot spot” just isn’t there.

Weather balloons have scanned the global atmosphere but could find no sign of the predicted “hot-spot” warming pattern that greenhouse gases would leave.”

Sources: Sources: (A) Predicted changes 1958-1999. Synthesis and Assessment Report 1.1, 2006, CCSP, Chapter 1, p 25, based on Santer et al. 2000; (B) Same document, recorded change/decade, Hadley Centre weather balloons 1979-1999, p. 116 , fig. 5.7E, from Thorne et al., 2005

With all the benefits of hindsight, it stood up extremely well. (Damn, but I did do a good job 🙂 )

There are claims I should not call it a “signature”, but here’s how it is: The top alarmist researchers called it a fingerprint or a signature, the graph explicitly states that the hot spot is the pattern caused by “well mixed greenhouse gases”, and basically, […]

Dr David Evans: The Skeptic’s Case

A new brief summary of the reasoning and evidence behind the skeptics case. –Jo

———————————————

The Skeptic’s Case Who Are You Going To Believe – The Government Climate Scientists Or The Data? Guest Post Dr David M.W. Evans

We check the main predictions of the climate models against the best and latest data. Fortunately the climate models got all their major predictions wrong. Why? Every serious skeptical scientist has been consistently saying essentially the same thing for over 20 years, yet most people have never heard the message — here it is, put simply enough for any lay reader willing to pay attention.

What the Government Climate Scientists Say

 

Figure 1: The climate models. If the CO2 level doubles (as it is on course to do by about 2070 to 2100), the climate models estimate the temperature increase due to that extra CO2 will be about 1.1°C × 3 = 3.3°C. [1]

The direct effect of CO2 is well-established physics, based on laboratory results, and known for over a century.[2]

Feedbacks are due to the ways the Earth reacts to the direct warming effect of the CO2. The threefold amplification by feedbacks is based on the […]

Influential people are getting the message: Gina Rinehart explains the science of climate change

Cover: Australian Resources and Investment Dec 2011

The key messages are not lost on the bright and influential, and even if the mass-media avoid the evidence, the facts are quietly storming their way through the echelons of power. For the future historians, here’s a glimpse of how information networks grow and evolve behind the scenes.

Once upon a time, the missing hot spot and the water vapor amplification were virtually unknown. In Jan 2009 2010, Tony Kelly (a member of the Royal Society) met David and me privately in Perth. He grasped the implications of the model amplification in a flash. There’s a world of difference between the certainty of the 1.2 C direct effect of CO2, and the highly uncertain assumptions that push it up to 3.3 C. Three months later, not coincidentally, the Royal Society was approached by deeply concerned skeptical members, and had to formally reconsider its position.

In June this year, we were lucky enough to dine with Matt Ridley, who likewise picked up the message, and is spreading it — see his acclaimed speech in November. A few weeks ago, I noticed Lord Lawson and Lord Turnbull similarly argued the same meme (though I […]

This is 90% certainty? Really? (Yet another paper shows the hot-spot is missing.)

Fu and Manabe agree the hot spot is missing

GRL June 2011.

Yet another study hunted for a form of the missing hot spot– and again the results show the models are unable to make useful predictions.

The upward rising trend predicted in the models is of critical importance. The models assume that the 1.1 degrees of warming directly due to CO2 will be tripled by feedbacks from humidity and water vapor. Studies like Fu and Manabe are looking to see if the assumptions built into the models are right. If relative humidity stays constant above the tropics throughout the troposphere, we should see the upper troposphere warm faster than the surface.

Fu and Manabe used satellite data rather than weather balloons, and compared the tropical upper troposphere to the lower middle troposphere during 1979 – 2010. (Other papers I’ve written about compared the upper troposphere to the surface, and mainly used weather balloons.)

“One of the striking features in GCM‐predicted climate change due to the increase of greenhouse gases is the much enhanced warming in the tropical upper troposphere”

Satellites cannot separate out the altitudes at narrow resolutions, as the radiosondes can, but they produce reliable data […]

Dr David Evans: Four fatal pieces of evidence

Dr David Evans lays out four crucial pieces of evidence, and calls for a debate with Prof Andrew Pitman. But the evidence is so unarguably strong for skeptics, we know that the name-calling-team-who-want-our-money will do anything to avoid a public debate. If the evidence is “overwhelming” why are they so unwilling to explain it? — Jo

Submission to the Inquiry into Carbon Tax Pricing Mechanisms

Dr David Evans

20 September 2011

Dr David Evans consulted full-time for the Australian Greenhouse Office from 1999 to 2005, and part-time to the Department of Climate Change from 2008 to 2010, modeling Australia’s carbon in plants, debris, mulch, soils, and forestry and agricultural products. Evans is a mathematician and engineer, with six university degrees including a PhD from Stanford University.

Global warming has become a scam. Let me explain how it works.

It has superficial plausibility. Yes, global warming is occurring. Yes, carbon dioxide is a greenhouse gas and levels are rising. And yes, every molecule of carbon dioxide we emit causes some global warming.

Many non-scientists think that proves the case, but it doesn’t. In particular, it doesn’t rule out the possibility that carbon dioxide is merely […]

The oceans, clouds and cosmic rays drive the climate, not CO2

Dr Noor van Andel

Dr Noor van Andel spoke at the Dutch Meteorological Institute (KNMI), provocatively concluding there is no observational evidence for the influence of CO2 on past or present climate. He has released a high caliber slide set. He is the former head of research at Akzo Nobel.

In the very long run, we need not mind about CO2 or global warming, but instead about higher [galactic cosmic ray] activity and global cooling. There is no way we can influence [galactic cosmic ray] activity, originating in active black holes and imploding supernovae.

Essentially he uses empirical evidence to draw the conclusion that most recent climate variability is due to Pacific Decadal Oscillation, and to Cosmic Ray effect as described by Svensmark. This fits with what William Kinninmonth explained and I described as essentially a massive pool of “stored cold” in the abyssal depths of the oceans, which erratically reaches up and pulls in heat from the insubstantial atmosphere above. Air temperatures are at the beck and call of the releases of this “cold” (yes I know cold is just an absence of heat). In El Nino years when the cold pool lies deep and unstirred, the incoming […]

Thorne 2010: A very incomplete history of the missing hot spot

Emails are coming in about the latest attempt to announce that they’ve “found the hot-spot”: Thorne et at 2010.

It’s already being used in NOAA press releases to repeat the same line about how a “new scientific study” supports the models. The aforementioned support is rather weakly phrased as being “broadly consistent” (which somehow means the same thing as being “90% certain” a catastrophe is on the way, right?).

But it gives them another chance to claim it’s been found:

This new paper extensively reviews the relevant scientific analyses — 195 cited papers, model results and atmospheric data sets — and finds that there is no longer evidence for a fundamental discrepancy and that the troposphere is warming.

It says something about how important the hot spot is that they keep “finding it”. (Even though they never seem to issue a press release saying it’s missing.) But since the data from the last warming spell came in ten years ago, there are only so many ways they can rehash the same numbers. So now they’re scraping the bottom of the barrel in desperation. This new study is not a “new scientific study”, it’s a new review. This paper tells us […]

This point is THE critical one. It was the first point raised in the Skeptics Handbook, developed in the Second Handbook; the point that Dr Glikson had no reply to; the point that tripped up Will Steffen, Deltoid, and John Cook. As a modeler there was the moment in August 2007 when David saw the graphs below and said, emphatically: This is it. It’s over for the climate models. –JN

Found: the hot spot? Not

The gap between real world data and thermometers is a make-or-break issue for the AGW theory. The models predict a hot-spot in the atmosphere above the tropics, but the weather balloons (called radiosondes) can’t find any sign of it. Most claims that the hot-spot has been found are not providing any new data, they are just massaging the same old numbers with a different statistical tool. Here are three variations (though the third is not a statistical-spin, it’s just nonsense).

1–Some AGW supporters claim that Santer et al has found the hot-spot. But his paper boils downs to a statistical reanalysis that suggests that due to noise and error, the hot-spot might be there. Santer hasn’t actually found the missing hot spot. He has a case, but it’s not a strong one. The statistical counterargument is at Climate Audit.
