Global warming, not so bad at all really: says NIPCC report and thousands of references

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

Debunking every IPCC climate prophesy of war, pestilence, famine, drought, impacts in one line

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, [...]

IPCC spin translated – the leaked Synopsis admits 97% of models fail

Joint Post: Geoff Sherrington and JoNova

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. : -)

Translating IPCC-spin:

“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 [...]

PR Wars: IPCC fights for relevance, halves warming, claims to be 95% certain of something vaguer

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 [...]

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 [...]

Donna Laframboise – Secret Santa leak of AR5 Working Group II material

BREAKING:All the files from Working Group II of AR5 are now available just as “ahem” the open-and-transparent-IPCC would want them. There are 661 files amongst 1 gigabyte of material. This includes their meeting in Japan, in Jan 2011 and a year later in San Francisco, and then Buenos Aires, 10 weeks ago.

Leaked — Working Group II drafts

Behind the scenes Donna Laframboise finds that there is a layer of aggressive activists who are privvy to the IPCC drafts process, and actively lobbying. WWF are pushing the IPCC to cite the WWF. They helped create Himalaya-gate where the IPCC ridiculously predicted the end of the massive Himalayan glaciers by 2035, and got caught embarrassingly. Donna’s book showed that “two thirds of the chapters in the 2007 IPCC report included among their personnel, at least one individual linked to the WWF. One third of the chapters were led by an WWF-affiliated author.” Apparently nothing much has changed.

Donna Laframboise writes:

My 2011 book, The Delinquent Teenager Who Was Mistaken for the World’s Top Climate Expert, documents the IPCC’s numerous credibility problems. Among these is the disturbing influence of green activists on what is supposed to be a rigorous [...]

Unleashed: Monckton releases his AR5 reviewer comments

Because the AR5 report is now leaked into the public domain, Christopher Monckton has released his AR5 review comments on the Lord Monckton Foundation site. Notably, Monckton does his absolute best to help the IPCC operate as a useful honest public service. In the most statesman-like manner, Monckton works from the principle that the IPCC’s credibility could theoretically be rescued. (How generous is he?) Monckton also provides a few peer reviewed papers that the team of hundreds of experts has missed — just the odd 450 references or so. As always, meticulously researched, carefully thought out, and with impeccable logic. The IPCC must be paying him well for this rigorous input… oh wait…

In order to produce a respectable useful document the IPCC has to improve:

The IPCC needs to address the failure of their past key predictions. Split up the science from the politics. (Political appointee’s can write their own chapter*, not rewrite the scientists ones). The alterations to the scientists final draft need to be marked as such and sent back to the expert reviewers. All references from gray literature (eg activist press releases) should be removed. To stop the goal posts moving, the IPCC should update projections [...]
