Warmist Scientist Admits: Our Models Were Wrong

MORE on the shock, global warming “pause” paper from warmists Santer, Mann et al !

via PA Pundits…

 

UPDATE via Climatism:

 

MAKE NO MISTAKE. This paper is massive. It basically reaffirms what climate sceptics (“Deniers”) have been stating for years – that despite record CO2 emissions over the past 20 years, there has been NO statistically significant global warming over this period.

There is a catastrophic problem with the UN’s billion dollar CMIP5 climate models that essentially drive the $trillion global warming industry. They are grossly overheated, leading to the panic, hysteria and fake news seen daily on the topic.

Something other than CO2 must be driving the climate. And The Godfather’s of global warming doom and gloom – Ben Santer and Mikey (hockey stick) Mann et al have released this *scientific* paper supporting the sceptical notion of a lower CO2 sensitivity than perceived by the “97%”.

It is being touted in the sceptic community as “Black Monday” owing to the release day.

Surely, this paper spells the beginning of the end for the greatest and most costly scientific fraud ever perpetrated upon mankind.

Even leading alarmist Ben Santer, lead author of a paper in Nature Geoscience, now admits the world isn’t warming as predicted by global warming models. Even Michael Mann, who produced the infamous hockey stick, has put his name to this paper.

From the abstract:

In the early twenty-first century, satellite-derived tropospheric warming trends were generally smaller than trends estimated from a large multi-model ensemble.

The problem is the models on which the global warming scare is based were simply wrong:

We conclude that model overestimation of tropospheric warming in the early twenty-first century is partly due to systematic deficiencies in some of the post-2000 external forcings used in the model simulations.

James Delingpole describes Santer’s colorful history in the climate wars since he was outed in the Climategate scandal.

Sceptical scientists identified this problem years ago:

New ‘Karl-buster’ paper confirms ‘the pause’, and climate models failure

“The gap between observations and models persists. The observed trend deviated by as much as −0.17 °C per decade from the CMIP5 (Coupled Model Intercomparison Project Phase 5; ref. 19) ensemble-mean projection1—a gap two to four times the observed trend.

The hiatus therefore continues to challenge climate science.”

– Nature Climate Change (PEER-REVIEWED STUDY)

“This paper published today in Nature Climate Change by Hedemann et al. not only confirms the existence of “the pause” in global temperature, but suggests a cause, saying “…the hiatus could also have been caused by internal variability in the top-of-atmosphere energy imbalance“.
That’s an important sentence, because it demonstrates that despite many claims to the contrary, CO2 induced forcing of the planetary temperature is not the control knob, and natural variability remains in force.”

The “pause/hiatus” in Global Warming is now nearing 20 YEARS. This despite *record* man-made CO2 emitted over the same period.

Don’t be at all surprised if – CNN, BBC, ABC, CNBC, LATimes, NYTimes, WaPo, The Age, SMH and the rest of the “climate change” obsessed sycophant media don’t report this massively inconvenient climate news. – Too many reputations, jobs, govt grants and funding are now at stake.

Watts Up With That?

The “uncertainty monster” strikes again

We’ve been highly critical for some time of the paper in summer 2015 by Karl et al. that claimed “the pause” or hiatus went away once “properly adjusted” ocean surface temperature data was applied to the global surface temperature dataset. Virtually everyone in the climate skeptic community considers Karl et al. little more than a sleight of hand.

No matter, this paper published today in Nature Climate Change by Hedemann et al. not only confirms the existence of “the pause” in global temperature, but suggests a cause, saying “…the hiatus could also have been caused by internal variability in the top-of-atmosphere energy imbalance“.

That’s an important sentence, because it demonstrates that despite many claims to the contrary, CO2 induced forcing of the planetary temperature is not the control knob, and natural variability remains in force.

Also of note, see the offset as designated…

Study reveals the atmospheric footprint of global warming hiatus

The warmist Met office’s latest hadCRUT4 data shows global temps are back down to 1997 levels, closely matching sat temps. Therefore the extremely inconvenient “Pause” or “Hiatus” can now be tracked for a period going on 20 years, despite *record* CO2 emissions over the same period. Not at all what we were promised by experts. The scam is over. The theory is bust.

atmos
They admit the hiatus, or pause, is still a puzzle: ‘processes remain unclear’. What is clear is that the observed temperature trend in the study period is unlike the carbon dioxide trend.

The increasing rate of the global mean surface temperature was reduced from 1998 to 2013, known as the global warming hiatus, or pause.

Researchers have devoted much effort to the understanding of the cause, reports Phys.org. The proposed mechanisms include the internal variability of the coupled ocean-atmosphere system, ocean heat uptake and redistribution, and many others.

However, scientists also want to understand the atmospheric footprint of the recent warming hiatus as the dynamical and physical processes remain unclear.

Professor Michael Asten urges calm – and a bit of honesty in the warming debate :

UN climate agency is exaggerating the effects of El Nino

  • THE AUSTRALIAN
  • NOVEMBER 28, 2015 12:00AM


The UN climate agency, the World Meteorological Organisation, has predictably hyped the global warming associated with this El Nino to encourage political leaders to action in next week’s Paris climate conference (”UN tips 2015 as hottest year”, 26/11).

However, its press release overlooks the full WMO discussion which notes that this El Nino is similar to three significant events in 1972-73, 1982-83 and 1997-98. It is not an unprecedented event, and past experience shows that prediction of the progress of El Ninos is notoriously difficult. The WMO quotes only surface temperature data, which may be subject to upward biases from meteorological stations sited in cities and ships that are thermal sources. The two data sets of lower atmosphere temperatures as measured globally using weather balloons and satellites were not used by the WMO, but they show a less alarming result — there is no upward statistical trend in global temperatures over the past 18 years, a feature much discussed in scientific journals as “the pause”.

Empirical scientists should be alarmed that while the most commonly quoted climate models predict a global temperature increase of 3C per century over this time, it is not happening. Rather than being panicked by the WMO press release, Malcolm Turnbull and Greg Hunt and their opposite numbers represented in Paris would serve us well by pausing their deliberations until science delivers a global temperature model consistent with measurement.

A “Settled Science” update via Andrew Bolt’s Blog :

Warmists who denied the pause now claim to explain it

I guess just the acknowledgement is progress, but I do think Matthew England at least owes an apology.

Matthew England contradicting former Senator Nick Minchin in April 2012:

NICK MINCHIN: …Basically we’ve had a plateauing of temperature rise. I mean we are in a warming phase. The world is either warming or cooling. It never stops doing nothing. It’s either warming or cooling. We’ve had a warming phase since the end of the little ice age, 150 years ago. In terms of global average temperature it peaked 1998 and it is effectively stable now, despite the increase in CO2. So there is a major problem with the warmist argument because we have had rising CO2 but we haven’t had the commensurate rise in temperature that the IPCC predicted.

ANNA ROSE: That’s just not true, Nick…

MATTHEW ENGLAND: What Nick just said is actually not true. The IPCC projections of 1990 have borne out very accurately…

Matthew England in December 2012:


… we’re halfway through this projected period. And the warming to date is consistent with that [IPCC] projection.

And so anybody out there lying that the IPCC projections are overstatements or that the observations haven’t kept pace with the projections is completely offline with this.  And so anybody out there lying that the IPCC projections are overstatements or that the observations haven’t kept pace with the projections is completely offline with this. The analysis is very clear that the IPCC projections are coming true.

But Matthew England today:

The near two-decade long “pause” in rising average global surface temperatures was a “distraction” that did not change long-term model predictions of a much ­hotter world this century, according to new research.

Climate scientists at University of NSW said “natural variability” could explain the slowdown or “hiatus” despite strongly rising ­levels of carbon ­dioxide in the ­atmosphere…

Research leader Matthew ­England said …  “It is simply due to decadal variability. Greenhouse gases will eventually overwhelm this natural fluctuation,” he said…

“Our research shows that while there may be short-term fluctuations … long-term warming of the planet is an inevitable consequence of ­increasing greenhouse gas concentrations,” he said.

“This much-hyped global warming slowdown is just a distraction to the task at hand”.

Maybe, maybe not. But this concession is interesting:


The paper also suggests that decadal climate oscillations were not pushing heat into the deep oceans, another explanation for the “missing heat” and absence of surface warming.

Also published now in Nature Climate Change, another paper trying to explain the pause that England once denied:

Despite a steady increase in atmospheric greenhouse gases (GHGs), global-mean surface temperature (T) has shown no discernible warming since about 2000, in sharp contrast to model simulations, which on average project strong warming.

UPDATE

via WattsUpWithThat :

Climate modeler Matthew England still ignoring reality – claims IPCC models will eventually win

…On the plus side, at least he acknowledges the existence of “the pause” now, but says it’s irrelevant. Whatever.
