Climategate 2 Falls at the First Hurdle?

Shock News! The David and Judy Show took to the road once again last night, aided and abetted by all the usual suspects. We’ll skip the Breitbarts, Hellers and Watts of this world and head straight for the now ex Prof. Judith Curry‘s “Climate Etc.” blog. There we will discover “Climate scientists versus climate data“, a guest post by ex NOAA scientist John Bates. According to John:

The most serious example of a climate scientist not archiving or documenting a critical climate dataset was the study of Tom Karl et al. 2015 (hereafter referred to as the Karl study or K15), purporting to show no ‘hiatus’ in global warming in the 2000s (Federal scientists say there never was any global warming “pause”). The study drew criticism from other climate scientists, who disagreed with K15’s conclusion about the ‘hiatus.’ (Making sense of the early-2000s warming slowdown). The paper also drew the attention of the Chairman of the House Science Committee, Representative Lamar Smith, who questioned the timing of the report, which was issued just prior to the Obama Administration’s Clean Power Plan submission to the Paris Climate Conference in 2015.

Regular readers of our humble scribblings will be well aware that here in Great White Con Ivory Towers we are firmly of the opinion that there never was a ‘hiatus’. Exhibit 1:

What’s all the fuss about then? Perhaps our old friend David Rose can explain in layperson’s terms? In his latest article for the Mail on Sunday, catchily entitled “Exposed: How world leaders were duped into investing billions over manipulated global warming data”, he assures us that amongst many other things:

The [K15] report claimed that the ‘pause’ or ‘slowdown’ in global warming in the period since 1998 – revealed by UN scientists in 2013 – never existed, and that world temperatures had been rising faster than scientists expected. Launched by NOAA with a public relations fanfare, it was splashed across the world’s media, and cited repeatedly by politicians and policy makers.

But the whistleblower, Dr John Bates, a top NOAA scientist with an impeccable reputation, has shown The Mail on Sunday irrefutable evidence that the paper was based on misleading, ‘unverified’ data.

It was never subjected to NOAA’s rigorous internal evaluation process – which Dr Bates devised.

Now “never subjected to NOAA’s rigorous internal evaluation process” isn’t quite the same thing as “manipulated global warming data”, but Mr. Rose has more!

The misleading ‘pausebuster chart’: The red line shows the current NOAA world temperature graph – which relies on the ‘adjusted’ and unreliable sea data cited in the flawed ‘Pausebuster’ paper. The blue line is the UK Met Office’s independently tested and verified ‘HadCRUT4’ record – showing lower monthly readings and a shallower recent warming trend

That graph looks convincing enough, doesn’t it? However there is a teensy weensy little upward adjustment in there that Mr. Rose is apparently unaware of, as NASA’s Gavin Schmidt pointed out late last night:

https://twitter.com/ClimateOfGavin/status/828082851585388544

This morning Carbon Brief has published a much longer takedown of the aforementioned purple prose by Zeke Hausfather, who points out amongst other things that:

What [David Rose] fails to mention is that the new NOAA results have been validated by independent data from satellites, buoys and Argo floats and that many other independent groups, including Berkeley Earth and the UK’s Met Office Hadley Centre, get effectively the same results.

As per usual Mr. Rose doesn’t stick to science, however dubious. He also dabbles in politics. On that front we are assured:

Karl’s ‘Pausebuster’ paper was hugely influential in dictating the world agreement in Paris and sweeping US emissions cuts. President Trump, above right, has pledged to scrap both policies – triggering furious claims by Democrats he is a climate ‘denier’ and ‘anti-science’.

Thanks to today’s MoS story, NOAA is set to face an inquiry by the Republican-led House science committee.

We’ll have much more to say on this controversy in the context of our “Alternative Facts” investigation in due course, but for the moment at least it looks to us as though the nth iteration of “Climategate 2” barely made it out of the starting gate. However Mr. Rose’s loyal army of “rebloggers, retweeters, plagiarisers and other assorted acolytes” and that “Republican-led House science committee” may of course have other ideas?

[Edit – February 5th PM]

Commentary on Judith Curry’s blog brought to light an article by Peter Thorne. He says, amongst many other things:

I worked for three and a bit years in the NOAA group responsible in the build-up to the Karl et al. paper (although I had left prior to that paper’s preparation and publication). I have been involved in and am a co-author upon all relevant underlying papers to Karl et al., 2015.

The ‘whistle blower’ is John Bates who was not involved in any aspect of the work. NOAA’s process is very stove-piped such that beyond seminars there is little dissemination of information across groups. John Bates never participated in any of the numerous technical meetings on the land or marine data I have participated in at NOAA NCEI either in person or remotely. This shows in his reputed (I am taking the journalist at their word that these are directly attributable quotes) mis-representation of the processes that actually occured. In some cases these mis-representations are publically verifiable.

A “rave from the grave” suggests itself at this juncture:

See if you can spot where Dan & Dan mention the term #Climategate.

It’s been a busy day! Several of my carefully crafted comments have ended up on Judy’s cutting room floor, but this one has eluded the red pencil thus far. I bring you this warming and educational nightcap created by an ad hoc team of celebrity international chefs for “warmists” around the planet:

Thank you and good night from May or May Not Land. I’ll see you all in the morning (UTC).

 

[Edit – February 7th]

Lot’s of pertinent papers just in from Great White Con guest author Kevin Cowtan of York University. Kevin is part of the by now world famous team of Cowtan & Way, who have long championed the cause of accurate Arctic temperature measurements. Kevin tells us:

The paper by Karl and colleagues corrected two known problems with the temperature observations: poor coverage of the Arctic, and a change from ships to buoys. Both had been known about since 2008:

http://www.realclimate.org/index.php/archives/2008/11/mind-the-gap/

https://www.ncdc.noaa.gov/sites/default/files/attachments/Improvements-NOAAs-Historical-Merged-land-Ocean-Temp-Analysis-1880-2006_0.pdf

and were further reported in subsequent papers:

http://onlinelibrary.wiley.com/doi/10.1029/2009JD012442/abstract

http://www.metoffice.gov.uk/hadobs/hadsst3/part_2_figinline.pdf

http://onlinelibrary.wiley.com/doi/10.1002/qj.2297/abstract

http://advances.sciencemag.org/content/3/1/e1601207

It took NOAA seven years to produce a paper correcting their temperature data, and even now their monthly updates still omit much of the Arctic. The UKMO temperature record is also missing much of the Arctic and only partially corrects the ship problem. Both lead to an underestimation of recent warming.

The agencies face an impossible dilemma – on one hand they have to slowly and carefully evaluate new results, and on the other they have to provide an up-to-date temperature record. Rather than rushing out corrections, they appear to have been extremely conservative.

So there you have it. For more accurate Arctic temperature metrics turn to Cowtan & Way and/or the Berkeley Earth Surface Temperature study! The long delay in improving the quality of the data published by NOAA and the UK Met Office has led to confusion amongst the public, politicans, and even other scientists. All three groups have been trying to understand a supposed “pause” in warming, which in our (humble?) opinion never actually happened. If you disagree with that assessment please feel free to take a good long look at izen’s animation at the top and then explain to us very slowly where you see a “hiatus”.

You may also wish to take a good long look at another guest post on the topic of “the pause”, this time authored by our very good friend Bill the Frog.

We like the UK Met Office’s new style. They have taken off the kid gloves, rolled up their sleeves, and they’re extracting the Michael from David Rose on Twitter with great glee:

It looks like we’ve now got a serious contender for our surrealist crown. We’ll have to try and up our game!

Facts About the Arctic in February 2017

The PIOMAS Arctic sea ice volume numbers for January 2017 have just been published. Yet another new record low for the date:

PIOMASIceVolumeAnomaly-201701

Here’s the PIOMAS gridded thickness for January 31st, courtesy of Wipneus at the Arctic Sea Ice Forum:

PIOMAS-20170131

Somewhat anomalously it shows the thickest ice some distance away from the coast of Greenland and/or Ellesmere Island. Here too is Andy Lee Robinson‘s updated PIOMAS “Arctic death spiral”:

arctic-death-spiral-1979-201701

Meanwhile yet more anomalously warm air is entering the Arctic Basin from both the Pacific and Atlantic sides:

CCI-T2Anom-20170204

That sort of thing has happened quite a few times over the 2016/17 freezing season, as you can see from this graph of cumulative Freezing Degree Days (FDD for short):

2017-02-03-DMI-FDD

The FDD graph is based on the same data as the probably much more familiar DMI “Daily mean temperatures for the Arctic area north of the 80th northern parallel” graph:

DMI-meanT-20170203

Things are warming up in the Arctic once again.

 

[Edit – February 5th]

Whilst we await the arrival of the forecast anomalous warmth, how are some other metrics coming along? Here’s the high resolution AMSR2 area and extent:

UH-Arctic-Area-2017-02-04

UH-Arctic-Extent-2017-02-04

It looks like they’re back in the “normal” range for now, does it not?

 

[Edit – February 6th]

Things currently still look fairly frosty over on the Pacific side of the Arctic, as you can see from the webcam at Utqiagvik (Barrow as was):

BarrowCam_20170206_225400

However over on the Atlantic side (and especially for “Richard”!) melting can now be observed on Svalbard:

isfjordradio-20170206

An extremely powerful cyclone off Greenland is pumping heat and moisture northwards:

Synopsis-20170206-18Z

Note that the cyclone’s MSLP fell to 940 hPa earlier today. This is the GFS precipitable water forecast for Wednesday lunchtime:

CCI-PWTR-20170206-12+48h

Finally, for the moment at least, here’s the current weather forecast for Longyearbyen in Svalbard:

2017-02-07-Longyearbyen-Fcst

All in all there’s plenty more heat and moisture on the way.

 

[Edit – February 13th]

The temperatures in Svalbard have now dropped back below freezing point:

Svalbard-Temps-20170213

As temperatures over parts of the Arctic Basin have reached zero degrees Celsius and above, Arctic sea ice extent has been declining:

UH-Arctic-Extent-2017-02-12

Now take a look at area:

UH-Arctic-Area-2017-02-12

Area has declined a lot! That’s because sea ice concentration is now noticeably <100% across much of the Arctic:

Bremen-AMSR2-20170212

There’s also been a discernable change in slope of the DMI freezing degree days graph:

DMI-FDD-20170213

 

[Edit – February 19th]

There’s been a late spurt of growth in both area and extent, which are now back in the pack of previous years:

UH-Arctic-Area-2017-02-18

UH-Arctic-Extent-2017-02-18

The newly frozen areas are currently still very thin:

SMOS-20170218

Meanwhile northern hemisphere snow cover has started to melt in earnest:

Alternative Facts About the Arctic in 2017

Yesterday I found myself in conversation with Nigel and “Steve” on Twitter about NOAA’s recent report on Arctic temperatures and the seemingly unrelated topic of Russian icebreakers. Apparently Nigel has been perusing “Steve’s” recent railing against NOAA’s “Red Hot Arctic” in 2016 on his “Deplorable Client Science” blog. Here’s how my conversation with Nigel went:

 

It appears that Nigel believes that an image like this:

JohannMahmastal

is far more relevant than an image like this:

SMOS-20170201

when it comes to determining the thickness of “the ice up in the north of Russia”!

Then of course there was my “conversation” with “Steve” after he butted in on my “debate” with Nigel. It went like this:

Followed the next morning by:

https://twitter.com/jim_hunt/status/827120539764457472

Just like Nigel, “Steve” still hasn’t got around to commenting on my map of Arctic sea thickness or explaining the significance of 2 Russian icebreakers NOT stuck in the East Siberian Sea.

[Edit – February 3rd 2017]

Some more pertinent facts, courtesy of CryoSat-2:

Cryosat_ESS_20170131

I’ve just submitted this article to a brand new learned journal. The Journal of Alternative Facts:

https://twitter.com/jim_hunt/status/827458574515318784

According to their article guidelines self references are highly desirable, so I figured I should add some.

 

[Edit – February 4th 2017]

Nigel still refuses to provide any more “evidence” about the Russian icebreakers allegedly “stuck in ice”, whilst “Steve” continues to ignore me:

https://twitter.com/jim_hunt/status/827807996331843584

The Journal of Alternative Facts article guidelines insist on peer review by politicians, so I’ve invited a few local, national and international politicians to comment on my draft paper:

Global Sea Ice Extent Reaches Lowest *Ever Level

Here once again is the up to date version of Wipneus’ graphic graphic, this time of global sea ice extent:

nsidc_global_extent_20170114

As you can see, global sea ice extent has just reached the lowest ever level in the National Snow and Ice Data Center’s satellite records going back to 1979. It was over a month later when the previous record was broken in February 2016, so there is plenty of time for the metric to fall further.

The 2017 curves in the NSIDC’s own extent graphs are coloured in a pale shade of blue. Even so they’re easy to pick out since both Antarctic and Arctic extent are at the lowest level for the date in NSIDC’s records by a considerable margin:

Chantarctic-20170115

Charctic-20170115

Antarctic sea ice extent is still falling, and the Arctic has been flatlining for several days now and more trouble is heading its way. Another Fram Strait cyclone is brewing, and this time around the storm’s minimum central pressure is already down to 957 hPa according to Environment Canada:

Synopsis-20170116-12Z

According to the current forecasts it will continue to spin over the central Arctic for several more days, driving export of sea ice via the Fram Strait:
