Gullible journalists are swooning today with more and glorious prophesies of disaster.
This from the team that relies on simulations that not only fail on global scales1, but they can’t predict regional2, local3, short term, continental, or polar effects4 either. They are also wrong about humidity5, rainfall6a,6b,6c, drought7 and clouds8, as well as the all-important upper tropospheric patterns too.9, 10
Speaking to the BBC earlier, Dr Pachaudri said today’s announcement was, categorically, the “strongest, most robust and most comprehensive” document that the IPCC has produced. — BBC
They are robustly, comprehensively, and consistently wrong. But it’s OK, they only want 0.06% of GDP (for now).
The IPCC says that the cost of taking action to keep the rise in temperature under 2 degrees C over the next 76 years will cost about 0.06% of GDP every year. Over the same period, world GDP is expected to grow at least 300%. – BBC

I decided that the IPCC Impacts report was irrelevant speculation because it utterly depended on the IPCC science report and the climate models which we already know are wrong. But the dedicated team at NIPCC show that, even if we take the claims of “impacts” working group seriously, they still come to nothing. Atmospheric CO2 is not a pollutant, there is little risk of famine due to our emissions or due to global warming. Life in the oceans is likely to adapt reasonably well as so many studies have shown, and less humans will die overall as a bonus. For those of you who enjoy well written, well researched arguments, and especially if you are looking for scientific references and the nuance of this debate, there is much to learn. The NIPCC reports are an invaluable reference for me. Careful scientific language is so much more informative than the full-gloss IPCC double-speak about theories which are consistent with uncertainties but not with observations – Jo

We could spend hours analyzing the new IPCC report about the impacts of climate change. Or we could just point out:
Everything in the Working Group II report depends entirely on Working Group I.
( see footnote 1 SPM, page 3).
Working Group I depends entirely on climate models and 98% of them didn’t predict the pause.
The models are broken. They are based on flawed assumptions about water vapor.
Working Group I, remember, was supposed to tell us the scientific case for man-made global warming. If our emissions aren’t driving the climate towards a catastrophe, then we don’t need to analyze what happens during the catastrophe we probably won’t get. This applies equally to War, Pestilence, Famine, Drought, Floods, Storms, and Shrinking Fish (which, keep in mind, could have led to the ultimate disaster: shrinking fish and chips).
To cut a long story short, the 95% certainty of Working Group I boils down to climate models and 98% of them didn’t predict the pause in surface temperature trends (von Storch 2013) . Even under the most generous interpretation, models are proven failures, 100% right except for rain, [...]

The IPCC Synthesis Report first order draft has been leaked (h/t Tallbloke) . It is part of the big Fifth Assessment report see the parts already released here. The Synthesis Report supposedly summarizes the science. In the real world the topic du jour is the plateau, pause, or hiatus in warming which the IPCC can no longer ignore. Instead the masters of keyword phrases test new bounds in saying things that are technically correct, while not stating the bleeding obvious. Luckily we are here to help them. : -)
“The rate of warming of the observed global-mean surface temperature has been smaller over the past 15 years (1998-2012) than over the past 30 to 60 years (Figure SYR.1a; Box SYR.1) and is estimated to be around one-third to one-half of the trend over the period 1951–2012. Nevertheless, the decade of the 2000s has been the warmest in the instrumental record (Figure SYR.1a).”
Translated: Yes temperatures are not rising faster as we predicted, even though more CO2 was pumped out faster than ever. Let’s ignore that this shows the models were wrong, the important thing is to [...]
For years we’ve been warned via the media that there was a risk of irreversible global catastrophe. Is the IPCC stepping back from those forecasts too? The words abrupt, irreversible, and tipping point didn’t make it into the Headline Points in 2013.
Reader Katabasis at Bishop Hill reports on the Royal Society meeting where abrupt and irreversible changes were discussed. Katabasis notes that in the IPCC Chapter 12 Table 12.4 many of the catastrophic changes being forecast are described as “unlikely” or “very unlikely” or even “exceptionally unlikely”. The only one now considered “likely” is that the Arctic might be ice free 40 years from now (which is a big step back from “ice free by 2013″ as some commentators predicted). Moreover confidence is low.
Will IPCC authors now correct Gore, Flannery, or other commentators when they tell us that CO2 emissions will probably lead to abrupt or irreversible ice sheet collapse, or collapses of the monsoonal circulation or Atlantic currents. Note the IPCC is saying “low confidence” for long term megadroughts, and monsoon changes, which means, “we don’t know” rather than “unlikely”. But why spend billions to prevent something you have low confidence will happen?

And the public conversation finally starts to move on to discussing not whether the IPCC is wrong, but why it was wrong, and what we need to do about it. Credit to Judith Curry and the Financial Post. I’ve posted a few paragraphs here. The whole story is in the link at the top. – Jo

Kill the IPCC: After decades and billions spent, the climate body still fails to prove humans behind warming
The IPCC is in a state of permanent paradigm paralysis. It is the problem, not the solution
The IPCC has given us a diagnosis of a planetary fever and a prescription for planet Earth. In this article, I provide a diagnosis and prescription for the IPCC: paradigm paralysis, caused by motivated reasoning, oversimplification, and consensus seeking; worsened and made permanent by a vicious positive feedback effect at the climate science-policy interface.
In its latest report released Friday, after several decades and expenditures in the bazillions, the IPCC still has not provided a convincing argument for how much warming in the 20th century has been caused by humans.
We tried a simple solution for a [...]
In answer to the excuse du jour: “The Ocean ate my Global Warming”.
Now that the plateau in air temperatures has lasted for 15 years, everyone, even IPCC lead authors, can see the “90% certain” models were 98% wrong. So the IPCC now claims the heat went into the deep abyss, which they didn’t predict, can’t measure accurately, and, even by the best estimates we have, has not been anywhere near large enough to explain the missing energy.
They predicted the surface air temperature would increase, but it didn’t. (The 1990 IPCC predictions about temperatures were so wrong the trends have come in below their lowest possible estimate.) They predicted the oceans would warm more than twice as much as they actually have (as best as we can tell). They did not predict the air temperature would level out for 15 years, and the oceans would suddenly start producing “natural cooling”.
The oceans are a bit of a mystery black box
There are 1.4 billion cubic kilometers of ocean out there — it’s so big it hid a 650 km volcano until two weeks ago. Only two people have been to the bottom ever (correction, three men), and they [...]
The race in the media continues: The UK Daily Mail (again), The Spectator, The UK Express. The headlines the IPCC must hate just keep coming, now in major newspapers and magazines. Finally, maybe, some of the media is starting to get it. At last also the IPCC is feeling the pressure to explain the halting of global warming and the poor performance of its climate models.
This is all well and good, but before we celebrate, ponder that if science journalists had been doing their job 10 years ago, the IPCC would have been put on the spot before before the wild evangelistic doom-fest of 2007 where national GDP points were roasted with every chapter. Billions could have been saved.
As I keep saying: The media is the problem. With good journalists, and real reporters, everything else gets better. Shine the light…

World’s top climate scientists told to ‘cover up’ the fact that the Earth’s temperature hasn’t risen for the last 15 years
But leaked documents seen by the Associated Press, yesterday revealed deep concerns among politicians about a lack of global warming over the past few years.
Germany called for the references [...]
We are over the peak. Years late, the IPCC concedes some territory and wears headlines they must hate (“Global warming is just HALF what we said“, “We got it wrong on warming“), but PR still rules, and in the big game, this will quickly spin to a minor bump. It’s a classic technique to release “the bad news” before the main report, to clear the air for the messages the agents want to stick.
Since 2007 they’ve burned through their credibility in so many ways: think Climategate, and getting caught pretending activist material was science, being busted for 300-year-typos like the Himalayan Glaciers, plus 15 years of no warming, no hot spot, models being wrong, droughts ending, and ice returning, all the while pouring scorn and derision on anyone who questioned them. The IPCC were being hammered and they had to change tacks. Now, for the first time, the IPCC is making a serious retreat, presumably in the hope of being able to still paint itself as “scientific” and to fight from a different trench. Anything to continue the yearly junkets and to save face. What they hope is that no one will notice that the deniers were right [...]
The oceans as measured by ARGO are warming, but that warming is not only far less than the models predicted, it is far less even than the instrument error.
The background of a crucial point
Everyone agrees: 90% of the energy in the Earth’s climate system is stored in the oceans. Rocks and sand don’t transmit the heat down, except at incredibly slow rates. The wil-o’-the-wisp-atmosphere hardly holds any energy. But water covers 70% of the surface, to an average depth of 3,700m, and it can store septillions of joules.
Climate models say the Earth’s energy balance is out of whack, and therefore 90% of the extra energy trapped by increasing greenhouse gases is stored in the ocean. The oceans are warming (probably), but the extra energy found in the top 700m of the world’s oceans is not enough. The modelers argued the heat was hidden below, that from 700m-2,000m. Skeptics argue the missing energy was flung out to space. This is the big enchilada, and as far as measuring oceans goes, everything changed in 2003 when we finally got the ARGO system, and that’s why it’s worth a closer look now.
