In the true spirit of satire Steve Hunter manages to pretty much expose the grand flaw.

Man-made global warming is unfalsifiable.
Scientists make predictions and test them. Only unskeptical scientists ignore the failures.
Flannery has missed a few. Bolt has a copy of Flannery’s Dam Predictions. For the record.
For your entertainment, the list of things that global warming can cause has been collected by NumberWatch:

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 […]
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 […]
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 […]
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]

Have the 1990 IPCC predictions been proved completely, unarguably and utterly wrong? Yes.
They predicted that if our emissions stayed the same, temperatures would rise by 0.3 C per decade, and would be at the very least 0.2, and the most 0.5. Even by the most generous rehash of the data, the highest rate they can find is 0.18 C per decade which is likely an overestimate, and in any case, is below the very least estimate, despite the world’s emissions of CO2 continuing ever higher.
Climate Scientist Matthew England called that “very accurate”. Since when did 0.18 = 0.3? (Shall we call it “climate maths”, or just call it wrong?) The IPCC had a whole barn wall to aim at, and a battalion of government funded gold plated AK-47s to hit the target, but they still missed.
Both England and the ABC owe Minchin an apology.
The un-Skepticalscience page uses a pea and thimble trick to argue the IPCC 1990 predictions were right (“Lessons from Past Climate Predictions: IPCC FAR”). As usual John Cooks site looks “technical” but uses complexity to hide the way they redefined the prediction in order to pretend it wasn’t wrong. Excuses excuses. Intellectual wordsmiths […]
Nir Shaviv, the well known astrophysicist from Israel, points out that climate sensitivity (according to the IPCC and co) has barely changed in 33 years. Therefore their predictions from the FAR (IPCC, First Assessment Report) in 1990 ought to mean something. Yet observations are now tracking outside and below even their lowest bounds of estimates. When will the IPCC admit those models need to change?

On IPCCs exaggerated climate sensitivity and the emperor’s new clothes Guest Post by Nir Shaviv (Reposted from ScienceBits , with permission. Thank you Nir). A few days ago I had a very pleasant meeting with Andrew Bolt. He was visiting Israel and we met for an hour in my office. During the discussion, I mentioned that the writers of the recent IPCC reports are not very scientific in their conduct and realized that I should write about it here.
Normal science progresses through the collection of observations (or measurements), the conjecture of hypotheses, the making of predictions, and then through the usage of new observations, the modification of the hypotheses accordingly (either ruling them out, or improving them). In the global warming “science”, this is not the case.
What do […]
What is most astounding about the human race is that people like Erhlich, who predicted vast coastlines would be evacuated due to rotting fish by 1980, or Oppenheimer with a black blizzard of sand covering a continent (by 1995), people who have long proven to be arrant failures at making predictions are still invited to speak or write. Some commentators still mention their name or quote them with a straight face.
Surely it takes a special kind of braggadocio and a certain delusion- of-grand-proportions for these would-be leaders to appear in public after predictions like these?
And yet they do.

Warwick Hughes has spotted a neat trifecta: whether it be rain, maximums or minimums, the BOM gets it wrong.
For this spring the Australian BOM predicted it would be dry and warm, instead we got very wet and quite cold. The models are so bad on a regional basis, it’s uncannily like they are almost useful… if they call things “dry”, expect “wet”.
On August 24 the Australian BOM had pretty much no idea that any unusual wetness was headed their way. Toss a coin, 50:50, yes or no. Spring 2010 was going to be “average”, except in SW Western Australia where they claimed “a wetter than normal spring is favoured.” What follows were 100 year floods, or at least above average rain to nearly every part of the nation bar the part that was supposed to be getting more rainfall. In the chart below, all shades of “blue” got above average rainfall. The dark blue? That’s the highest rainfall on record.

Monday, 20 March 2000. Look out! Back when every witchdoctor had a PR agent and newspapers dutifully repeated their latest crystal ball incantation, it was reported (without so much as a caveat) that there would soon be no more white Christmases in London, and worse, soon “kids will not know snow”. Gone too would be the scenes that inspired glorious impressionist images, and lyrical poetry. Are you in tears yet? The travesty!
Pity the poor shop owners who were trying to order stock based on met office “forecasts”. Back in 2000, shop owners were not bothering to stock sledges.
No more snowmen in England!
h/t to Bernadette and Trevor who spotted this gem.
Snowfalls are now just a thing of the past
By Charles Onians, 20th March 2000
Britain’s winter ends tomorrow with further indications of a striking environmental change: snow is starting to disappear from our lives.
Sledges, snowmen, snowballs and the excitement of waking to find that the stuff has settled outside are all a rapidly diminishing part of Britain’s culture, as warmer winters – which scientists are attributing to global climate change – produce not […]
