Road Trip Update: What I'm doing Wednesday and Thursday

Having driven just over 800 miles around North Carolina, getting USHCN and GISS stations, like the one in Fayetteville NC yesterday, I’m pretty tired. But I’m at the middle of the trip, a trip made possible by the donations of many readers and supporters like you. Thank you, most sincerely for funding this trip. I’m getting lots of stations, but I’ve kept the centerpiece private until now.

Tomorrow, by an invitation sent almost two months ago, I am meeting with Dr. Thomas Karl and many of the principal scientists at the National Climatic Data Center (NCDC) in Asheville, NC. I will also be giving a presentation that will include many of the things presented here on this blog, and some that haven’t been.

Here is the meeting agenda prepared by NCDC: watts-visit-ncdcbb PDF file.

I’ll be relaying a couple of communications and have some questions. Feel free to pose some here. The visit has been labeled as an “exchange of ideas and information”, which I’m all for as long as a hockey game doesn’t break out.

More station surveys in western NC and into Tennessee for the weekend. I hope to survey 20-25 on this trip.

Sign up here if you’d like to survey some in your state: www.surfacestations.org

Or if you can’t do surveys but would like to help there’s always the donation button at right to fund the next trip.

Be sure to check out that Asheville station, Rev. It’s supposed to be the jewel in the CRN crown.
REPLY: I have a personal tour Thursday

The NCDC has posted the adjustments to the USHCN:
http://www.ncdc.noaa.gov/oa/climate/research/ushcn/ushcn.html
The total of which is illiustrated here:

Many of us would like the same simple explanations and graphics for the adjustments to global temperature.

I’ve heard that March 2008 was supposedly the warmest on record (over land) globally. Yet the U.S. Climate Summary clearly shows that March is below average which makes three or four months in a row. I’ve also read that Sydney AU has just experienced its coolest summer in 50 years. Is it really possible for the US and Australia to be significantly cooler and the rest of the world so much hotter that the average is the warmest on record? I see this as one real unusual event, though I am not a scientist (bet you can tell) just one who avidly believes that global worming is a crock.
I remain hopeful that I will see the day when the cooling trend is significant enough and lasts long enough for Al Gore to be told to shut up.

April 22, 2008 5:01 pm

Ok, I estimate 5 Cracker Barrels between that sign and your destination.
REPLY: I’ve been using Bojangles as mile markers, seems to be more of those than cracker barrels. And I’ve yet to visit either.
Eating is restaurants here is tough, they allow smoking everywhere. I bailed on dinner tonight midway because person next to me lit up. Not likely to change here, as NC is a Tobacco driven economy. Great roads though, blows the California road system off the map in quality and coverage.

I’m constantly amazed at the apparent fact no one seems to question these “adjustments.” Anytime you allow ANYONE to fudge a number regardless how sincere they are, they are still fudged numbers and not woth a tinkers damn as far as I’m concerned.

Bojangles was listed in my original self censored post, along with Cracker Barrel, which may have a non-smoking section, Chick Fil A, and Waffle House.
WARNING: I STRONGLY ADVISE AGAINST EATING AT A WAFFLE HOUSE.
If you head up into the Smokies on your way to Tennessee, you can may be able to buy boiled peanuts, whatever the hell those are, or a confederate flag, on the NC side. When you come down in Tennessee you’ll find yourself in Fisherman’s Wharf South (Gatlinburg), then on past Dollywood and the the NASCAR museum, and a dozen huge dinner theaters for families on the road to Knoxville–really a weird area.
REPLY: There’s a Waffle House right next to my hotel, based on appearance alone (rust and window grime is never inviting) I’ve crossed it off the list. Been to Gatlinburg a long time ago, I’ve setup a “anti crap vortex field generator” on my vehicle for just such an occasion where I’ll have to push through the zone there.
I may use the bathroom at Bojangles, just to say I’ve been there. Cracker Barrel may be worth a shot as cultural experience. Chick Fil-A is actually quite good.

I had a feeling this is where your trip was heading. Just returned from there myself, as this is where my son and grandkids live, beautiful part of the country for sure. I always check the temps in Marshall NC, just north of Asheville, since this is where they live. Strong downward trend historically last time I checked. Don’t mention this to your host they may feel obligated to adjust it since it’s in their backyard:) Good luck looking forward to your reports on meeting.

jeez: Ah, those Cracker Barrels. The gift sections are the most banal things I’ve ever seen. Well, close (there is the NY Times editorial section). But they have all those cool antiques hanging from the ceilings! I’d buy those antiques, but not those godawful “gifts”!
they allow smoking everywhere.
In North Carolina smoking is required. (Even the airports had public ashtrays last time I was down there.) As you say, it’s half the economy down there.
I’ve heard that March 2008 was supposedly the warmest on record (over land) globally.
Those are surface measurements. I don’t think the satellites have as big a bounce.

I see you are meeting with Peterson. I can’t wait to read his new paper claiming “there was no consensus in the 1970s that the Earth was headed for a new ice age”. In fact, as I understand it, his paper will claim that “a review of the literature suggests that greenhouse warming even then dominated scientists’ thinking”.
Maybe that is true, maybe not, but I can’t wait to test his search terms on Google Scholar, with some of my own. Of course, my own search terms will be derived from what I found in the New York Times archive, which clearly shows a much higher degree of anxiety of a new ice age during the 1960s and 1970s than global warming.
Why the NYT? Well, I suspect more people read the NYT than the read scientific journals of the era. So public opinion then was driven by the media (such as NYT) and not by the scientific literature, much as it is today. At the end of the day, Peterson may be right about the scientific media, but wrong about the public media.

Mr. Watts,
Well done, good work. Plaudits.
So the NCDC guys at least appear to have some concern for science, good for them. Can you imagine the sh*t-storm if the NCDC announced they were revising the national temperature record, downwards!! Even enlarged error bars would be fatal.
Hint: They may also be looking for a way out of this quandry.
Just a thought: perhaps they will have some insight into “Where’s Waldo” as Steve Mcintyre has labelled the issue of the rise in the Rest Of The World’s land surface temperatures?

The restroom at the Bojangles in South Boston is the most disgusting indoor plumbing I have ever seen. Hell, it’s worse than most Forest Service two-holers.
I’ve been to some WH’s that are not all that bad.
Never ate af a Chick Fil-A, never found one with truck parking.
Cracker Barrels are not bad, and most have no-smoking sections.

Jack Koenig: As a neophyte R&D data aquisition technician in the medical prosthesis industry, I was constantly amazed that I was never allowed to commit raw numbers to storage. Rather I was always instructed to process raw data through someone’s magic formula prior to storage. Being of a more conservative bent, I usually privately set up a file of the raw data as well as the requested finagled numbers. On more than one occasion I saved someone’s butt when it was discovered their massaged numbers lied. Not once was I ever praised…
Now I’m a bit older and wiser!

Wow, an actual sit-down meeting with the one who signed off on the CRN siting standards.
It would be nice to know, first, if they have any records, pictures, or detailed metadata that is NOT archived somewhere. They had to get field reports on their installations and changeovers. Detail the problems people have had finding the proper sites.
Second, get their input on the use of reporting period (GISS, HadCRU and NCDC all use different ones).
I know, too many questions, not enough time.
We’ve all seen your presentation. The quality map alone is a telling part of the display, along with the recent addition of the FLIR. Knock their socks off, Anthony…

2. Can we get the code for the homogenization based on Menne’s appraoch.
3. Why is the station history file not up to date ( see atmoz work)
4. Can we get CRN data in an easier way, right now we have to scrape the web
site. St. Mac wrote a script, but its R. So an FTP site of CRN data.
5. How will CRN be phased in?

I’d be curious as to why there appear to be different adjustments on a seasonal basis (check AZ Childs for monthly data plot).
I’d also note that ND Mott was moved within the last three weeks or so with no update at the NOAA MMS database as of 23APR2008. Extra effort (and a pleasant overnight stay in town) was required to locate this one.
REPLY: Thanks Eric for the extra effort. I can tell you the lag is related to NWS reporting and data entry at NCDC. I’ll ask about the usual turnaround time.

“Ipsos-Mori polling data, published last week by the Financial Times, shows that, over the 12 months to January 2008, the proportion of those in Britain declaring “the environment” to be their biggest concern fell from almost 20 per cent to just 8 per cent. In the US battle for the Presidency, a recent major poll put interest in ‘global warming’ as a key issue at zero!”

In addition to the seasonal adjustments, it appears that disproportionate weight is given to February temperature data in calculating an annual “mean”. What scientific basis is there for this, given that they are apparently capable of doing ~5 other adjustments?

Tom in Florida
April 23, 2008 4:21 am

I would like to know if the comparisons between Waffle House and Cracker Barrell are raw data or have they been smoothed and adjusted? I would think there would be a +3.95 bias for Waffle House from real Southerners with a corresponding -1.75 bias from everyone else who has never eaten grits. There is also an added -5.9 bias againt Waffle House for those who have never used an outhouse. By the way, does your itinerary take you anywhere close to Big Al’s GHG producing monstrosity?

I think AGW skeptics will have done a great service to the survival of the human species by our constant work to demonstrate that human generated CO2 is not involved in a major way in climate change. I do believe that future generations will thank us for it. That is not to say that we probably agree with most “environmentalists” that our earth needs to be looked after and should not be forever be subjected to unmitigated development, overpopulation and over use of land etc (see R Pielke etc). This will become evident if the world does actually freeze over in the next 20-50 years.

Scientists are personally invested in their data for any number of reasons, e.g., say the public health lab providing data for a number of interdepartmental purposes. A technician, or their manager, adjusts data for ‘good reasons’, to ‘make it more accurate’, e.g., in the case where redundant tests or multiple methods are used. In every case, at some level, a fraud is being perpetrated; perhaps harmless, but with the intent to deceive someone, even if never ‘seen’ in fact.

This historical warming/cooling thing has taken curious twists and turns. Many years ago, before publishing became so polarized, the warmers and coolers got about equal press. Then, sat some point, and I think it started with the cooling media blitz, it became one sided. One of those happenings you look back for, but do not notice while it is happening. In any event, the appearance is that at one of the AAAS or other meetings, the warmers and coolers went off in the corner and flipped a coin, and all got on the same campaign bandwagon. For funding, of course. The warmers won the coin toss.
John Goetz, I hope you share with us the results of your search. I would love to know if it supports my shaky memory of the events of the time. And, I believe you are correct in believing that the media, even back then, drove public perception more than the scientific journals. And why wouldn’t it? What percentage of the citizenry are scientists? Scientific literacy drops every year in this country, and the results are obvious, aren’t they?

If the data are ever to be made useable, the station histories have to be cleaned up. Bite the bullet and go back to the reporting sheets, if they still exist, and re-digitize (locations and temps) starting from the present and working backwards. Also go interview the observers for recollections about micro-siting issues. Try to find out how much bias has crept in during the last couple of decades.

A place to see in Asheville, if you like astounding architecture at all, is St. Lawrence Basilica, right downtown. They give tours of the Church on Sundays. Or you can probably walk around it after a noon mass any week day. You must, if at all possible, see the belfry stairs, because you will question how they can possibly stay up.
St. Lawrence has a 135 foot by 80 foot elliptical dome of tile masonry, without ANY steel reinforcement. The main floors are on similar vaults (also unreinforced) and the tile vaulted stairs to the choir in the bell towers have no internal supporting columns, and also NO steel reinforcement or wood beams anywhere at all. Really neat.
It was built by Rafael Guastavino, the vault builder who did St. John the Divine main dome in NYC, and Bridgemarket under the Queensborough bridge (and about a 1000 other tile vaulted structures around the country). He aslo worked on Biltmore House there in Asheville.
He is buried in a crypt the main church — almost unheard of since the seventeenth century .

But in this case, they could probably say you are feeding the “Deniers” their talking points, which keeps the public from realizing that if we don’t fix the AGW problem now, we are all doomed. This, of coarse, is a direct threat to national security, and you’ll be arrested under provisions of the patriot act, swept away to some secret prison for AGW deniers, and never be heard from again. 🙂

Offtopic, but interesting, regarding the warming of Mars
Glaciers reveal Martian climate has been recently active

PROVIDENCE, R.I. [Brown University] – The prevailing thinking is that Mars is a planet whose active climate has been confined to the distant past. About 3.5 billion years ago, the Red Planet had extensive flowing water and then fell quiet – deadly quiet. It didn’t seem the climate had changed much since.
Now, in a research article that graces the May cover of Geology, scientists at Brown University think Mars’s climate has been much more dynamic than previously believed. After examining stunning high-resolution images taken last year by the Mars Reconnaissance Orbiter, the researchers have documented for the first time that ice packs at least 1 kilometer (0.6 miles) thick and perhaps 2.5 kilometers (1.6 miles) thick existed along Mars’s mid-latitude belt as recently as 100 million years ago. In addition, the team believes other images tell them that glaciers flowed in localized areas in the last 10 to 100 million years – akin to the day before yesterday in Mars’s geological timeline.

I wonder what could have changed Mars’ climate so markedly?

You have done yoeman’s work with your surfacestations audit effort.
But, here’s a question. If each station has a person or organization responsible for it, why hasn’t the the NCDC simply distributed an e-mail to all of those people and requested the same basic information you are getting through the audits (measurements, photos etc)?
If each station has a keeper/volunteer to chaperon its maintenance, why wouldn’t the organization that relies on the data, and likely paid for the equipment, have the authority to conduct an internal audit of all stations?
And why would that organization allow such poor installations to exist? Proper installation of new equipment should be mandatory and verified by documentation.
Just a thought.

April 23, 2008 3:41 pm

Anthony,
I echo Bob Tisdale’s appeal for a simple explanation of NCDC’s adjustments of station temperature data and their significance. A while ago, I became curious about the temporal and spatial variations in surface temperature and chose to examine the average monthly data for the last century (1987 – 2005) from several stations. I was perplexed by the significant differences between the monthly and annual temperature trends for a specific station. The differences in temperature trens between nearby (< 100 miles) stations was equally perplexing. I lost interest in my project when I realized that NCDC’s adjustment may have confounded the data.
Recently, I revisited the data from one station that I had previously selected (Fort Morgan, CO – 053038). This time, I elected to examine TMAX and TMIN compared to TAVG. I was surprised to the stability of the step-wise trends in both monthly and annual data for the difference between TAVG and TMEDIAN (delT). It showed the following: 1) 1897-1912: annual delT ~ +1deg F, 2) 1913-1965: annual delT ~ -0.4 deg F, and 3) 1965-2005: annual delT ~ 0.0.
REPLY: I’ll send it up the food chain.
The effect of the 1912 step-wise change varied month-to-month but was significant for all twelve months. The effect of the 1965 step-wise change primarily affected winter months, i.e., DJF. Lesser adjustment in 1987 and 1996 were apparent.
It’s not apparent to me whether TAVG, TMAX, TMIN or all of the above were adjusted. As far as I am concerned, the data for the Fort Morgan station is useless.

Sorry I missed you. I haven’t yet lept into the 21st century with mobile email yet. Was a lovely evening for an autocross under the lights at the Western NC Ag Center though. Spectacular drive up there too. Just gorgeous this time of year.
Congrats on all the accomplishments and have a safe trip back.

If you like pancakes and maple syrup, you should definitely take Cracker Barrel for a spin. Especially since those are probably banned substances in California.

Make sure it’s REAL maple syrup, though!
