Warmist father Hans Joachim Schellnhuber of 2C temperature limit admits it's a political goal.
Quote:
Hans Joachim Schellnhuber, a top German climate scientist who helped establish the 2-degree threshold, stressed it was a policy marker: “Two degrees is not a magical limit — it’s clearly a political goal,” says Hans Joachim Schellnhuber, director of the Potsdam Institute for Climate Impact Research (PIK). “The world will not come to an end right away in the event of stronger warming, nor are we definitely saved if warming is not as significant. The reality, of course, is much more complicated.” Schellnhuber ought to know. He is the father of the two-degree target. “Yes, I plead guilty,” he says, smiling. The idea didn’t hurt his career. In fact, it made him Germany’s most influential climatologist. Schellnhuber, a theoretical physicist, became Chancellor Angela Merkel’s chief scientific adviser — a position any researcher would envy.
Really...when your supposedly braniacs scientific community is constantly coming with excuses to explain the pause...you can't blame us deniers for being a tinny bit close minded ..
“It's easier to fool people than to convince them that they have been fooled.”

36) The models really do explain the "pause" [debunked] [debunked] [debunked]
37) As soon as the sun, the weather and volcanoes – all natural factors – allow, the world will start warming again. Who knew?
38) Trenberth's "missing heat" is hiding in the Atlantic, not Pacific as Trenberth claimed
[debunked] [Dr. Curry's take] [Author: “Every week there’s a new explanation of the hiatus”]
39) "Slowdown" due to "a delayed rebound effect from 1991 Mount Pinatubo aerosols and deep prolonged solar minimum"
40) The "pause" is "probably just barely statistically significant" with 95% confidence:
The "slowdown" is "probably just barely statistically significant" and not "meaningful in terms of the public discourse about climate change"
41) Internal variability, because Chinese aerosols can either warm or cool the climate:
The "recent hiatus in global warming is mainly caused by internal variability of the climate" because "anthropogenic aerosol emissions from Europe and North America towards China and India between 1996 and 2010 has surprisingly warmed rather than cooled the global climate."
[Before this new paper, anthropogenic aerosols were thought to cool the climate or to have minimal effects on climate, but as of now, they "surprisingly warm" the climate]
42) Trenberth's 'missing heat' really is missing and is not "supported by the data itself" in the "real ocean":
"it is not clear to me, actually, that an accelerated warming of some...layer of the ocean ... is robustly supported by the data itself. Until we clear up whether there has been some kind of accelerated warming at depth in the real ocean, I think these results serve as interesting hypotheses about why the rate of surface warming has slowed-down, but we still lack a definitive answer on this topic." [Josh Willis]
43) Ocean Variability:
"After some intense work by of the community, there is general agreement that the main driver [of climate the "pause"] is ocean variability. That's actually quite impressive progress."
44) The data showing the missing heat going into the oceans is robust and not robust:
" I think the findings that the heat is going into the Atlantic and Southern Ocean’s is probably pretty robust. However, I will defer to people like Josh Willis who know the data better than I do."-Andrew Dessler. Debunked by Josh Willis, who Dessler says "knows the data better than I do," says in the very same NYT article that "it is not clear to me, actually, that an accelerated warming of some...layer of the ocean ... is robustly supported by the data itself" - Josh Willis
45) We don't have a theory that fits all of the data:
"Ultimately, the challenge is to come up with the parsimonious theory [of the 'pause'] that fits all of the data" [Andrew Dessler]
46) We don't have enough data of natural climate cycles lasting 60-70 years to determine if the "pause" is due to such natural cycles:
"If the cycle has a period of 60-70 years, that means we have one or two cycles of observations. And I don’t think you can much about a cycle with just 1-2 cycles: e.g., what the actual period of the variability is, how regular it is, etc. You really need dozens of cycles to determine what the actual underlying variability looks like. In fact, I don’t think we even know if it IS a cycle." [Andrew Dessler]
47) Could be pure internal [natural] variability or increased CO2 or both
"this brings up what to me is the real question: how much of the hiatus is pure internal variability and how much is a forced response (from loading the atmosphere with carbon). This paper seems to implicitly take the position that it’s purely internal variability, which I’m not sure is true and might lead to a very different interpretation of the data and estimate of the future." [Andrew Dessler]
48) Its either in the Atlantic or Pacific, but definitely not a statistical fluke:
It's the Atlantic, not Pacific, and "the hiatus in the warming...should not be dismissed as a statistical fluke" [John Michael Wallace]
49) The other papers with excuses for the "pause" are not "science done right":
" If the science is done right, the calculated uncertainty takes account of this background variation. But none of these papers, Tung, or Trenberth, does that. Overlain on top of this natural behavior is the small, and often shaky, observing systems, both atmosphere and ocean where the shifting places and times and technologies must also produce a change even if none actually occurred. The “hiatus” is likely real, but so what? The fuss is mainly about normal behavior of the climate system." [Carl Wunsch]
50) The observational data we have is inadequate, but we ignore uncertainty to publish anyway:
"The central problem of climate science is to ask what you do and say when your data are, by almost any standard, inadequate? If I spend three years analyzing my data, and the only defensible inference is that “the data are inadequate to answer the question,” how do you publish? How do you get your grant renewed? A common answer is to distort the calculation of the uncertainty, or ignore it all together, and proclaim an exciting story that the New York Times will pick up...How many such stories have been withdrawn years later when enough adequate data became available?"
51) If our models could time-travel back in time, “we could have forecast ‘the pause’ – if we had the tools of the future back then” [NCAR press release]
[Time-traveling, back-to-the-future models debunked] [debunked] ["pause" due to natural variability]

New rule....You can't call yourself open-minded when you are close-minded to anything supported by the preponderance of scientific evidence, consensus and the scientific community at large.
Anyhow, score another goal for skeptics - he admits 2 degrees Celsius was a political and not a scientific determination.
Everything about AGW is political. Science is only used to support a political agenda. The science has been "settled" out of the picture.
