Giving thanks

31 12 2007

thanks.png

As this year draws to a close, I think back about what I’ve accomplished on this blog in the last year, and it occurs to me that I have a lot of people to thank. It truly has been a team effort in a lot of ways, with many people contributing from many different angles to help make the work I’m doing a possibility.

First and foremost, I’d like to thank Steve Thompson of Assemblyman Rick Keene’s office. It was his mention in an email to me ”that Russ Steele and I ought to get together” that started me on the path to study climate change from the data gathering aspect. Of course Russ and I had similar ideas, but we just didn’t know about each other, and knowing that there’s somebody else nearby that thought like I did whom I could converse with, was really a boost. Of course on the political front, I should also thank the local activist group ”Esplande League”, because if they hadn’t worked so hard to keep me from being re-elected to the local school board, I never would have had the time to pursue this research.

I owe Russ Steele a lot, not only for the many stations he’s surveyed, and for the encouragement and support, but also for introducing my work to many people, including Steve McIntyre of Climate Audit. It wasn’t until Steve took notice that things really began to take off. Steve has been most gracious in helping to promote my work and for offering me the ability to co-author on his blog.

And there are many others, I can think of the many volunteers on surfacestations.org that have contributed many ideas, data sorting and spreadsheet macros that saved me time and effort, and made the project’s data analysis better. Gary Boden, Chris Dunn, Joel McDade, John Goetz, Barry Wise, and Eric Gamberg have all made significant contributions to the project via surveyed stations and or improvements to the survey process and analysis.

Super surveyor Don Kostuch, has been traveling the country and surveys new stations every week. He is leader of the station surveyors not only in terms of quantity, but of quality too. His surveys are always carefully done. 15 year old Kristen Byrnes and her dad have surveyed almost all of New England single handedly.

One volunteer, Arthur Edelstein, I owe a great deal to because he did some significant data capture and collation that I wouldn’t have been able to do myself in the fraction of time that he did it in.

I owe Dr. Roger Pielke Sr. a debt of gratitude for his faith in my work and his encouragement, along with his assistant, Dallas Staley, who has pulled many an obscure request for data or publications out of nowhere, even after hours.

Then there’s all the other blogs and newspaper authors out there that have promoted what I’m doing.  Joe D’Aleo of ICECAP comes to mind, and does Barry Hearn and Steve Milloy of JS for publishing my “How not to measure temperature” series, and Kate from Small Dead Animals for being a regular traffic driver.  There’s Evan Jones, who is my most prolific and enthusiast commenter, along with regulars George M., Papertiger, Larry Sheldon, and Stan Needham. Let’s not forget Steven Mosher and Jeez, for putting up with my silly rants at dinner with Mac at AGU. Jeez also footed the dinner bill, and so deserves double thanks.

Local blogger Lon Glazner deserves a nod for blogging some early support and for some mental stimulus on thermometers that got me fired up last spring.

In the newspaper realm, Ryan Olson of the local Chico Enterprise Record, not only for the stories he’s done, but for putting up with my complaints about Moveable Type and helping me migrate to WordPress where I’ve been able to make a better product.  I thank Bill Steigerwald of the Pittsburgh Tribune whose article launched me into national attention. And finally, Evan, who did a really balanced and fair article even though I feared the worst.

Then there’s the 300 plus volunteers for www.surfacestations.org Thank you each and every one.

I owe you all a debt of gratitude. Thank you. If I’ve missed anyone, don’t be shy about speaking up.

There’s a few that deserved coal this year, but I’ll leave them nameless.





Weathering and Thermometer Shelters

27 12 2007

Former Virginia State Climatologist Patrick J. Michaels wrote an op-ed about his paper with Ross McKitrick from Canada’s University of Guelph in an American Spectator column today about the surface temperature record. This paragraph really caught my eye: “Weather equipment is very high-maintenance. The standard temperature shelter is painted white. If the paint wears or discolors, the shelter absorbs more of the sun’s heat and the thermometer inside will read artificially high. But keeping temperature stations well painted probably isn’t the highest priority in a poor country.”

The Stevenson Screen experiment that I had setup this summer is living proof of this.

Compare the photo of the whitewash paint screen on 7/13/07 when it was new with one taken today on 12/27/07. No wonder the NWS dumped whitewash as the spec in the 70’s in favor of latex paint. Notice that the Latex painted shelter still looks good today while the Whitewashed shelter is already deteriorating.

Whitewashed Screen on 12/27/07

The whitewash coating I used was from a formula and method provided to me by a chemist at the US Lime Corporation, who is an expert on whitewash. He said the formula was true to historical records of the time when whitewash was used on the shelters. I was amazed to find that after just a few short months, my whitewash coating had lost about 40-50% of it’s surface area. Perhaps there was a mistake in the formula, or perhaps whitewash really is this bad at withstanding weathering.

In any event the statement of Patrick Michaels “Weather equipment is very high-maintenance. The standard temperature shelter is painted white. If the paint wears or discolors, the shelter absorbs more of the sun’s heat and the thermometer inside will read artificially high.” seems like a realistic statement in light of the photos above. The magnitude of the effect in the surface temperature record has yet to be determined, but it seems clear that shelter maintenance, or lack thereof, is a significant micro-site bias factor that has not been adequately investigated nor accounted for in the historical temperature record.

I’ll have more on this experiment soon including temperature time series graphs showing the difference between bare wood, latex painted, and whitewashed shelters.





Blogging Holiday – please drive/bike/walk safely

23 12 2007

polar bear laughing

I’m taking a few days off blogging for friends and family. Seeing the pandemonium that has gripped the streets of my town while people scurry about trying to pull off that last minute shopping, and seeing my in-laws already getting into a small accident (even though they tried to avoid the traffic glut) and seeing local cycling enthusiast Ed McLaughlin get into a serious biking accident reminds me to remind you to drive, bike, and walk safely this holiday.

Watch for ice, it’s cold out there, don’t slip like the polar bear!

When I return I’ll have an update on my Stevenson Screen paint experiment.

In the meantime I wish each and every one of you a joyous Christmas holiday and I want to thank all of you for the help and support this year on this blog and in the www.surfacetstations.org project.





Moon and Mars show tonight, Sunday Dec 23rd

23 12 2007

Sky note:

 After sunset on Sunday, Dec. 23rd, the full Moon and Mars will rise in the east less than 2 degrees apart. They’ll be two brightest objects in the evening sky, as Mars is very near it’s closest approach (opposition) to Earth, which happened just a couple of days ago. 

It will look something like this:

Record cold events around the world in 2007

21 12 2007

Below is an opinion from the Washington Times by Geophysicist David Denning, to which I’ve added photos and links to the events he’s written about.
 

A caveat: I caution the reader that annual weather does not equate to long term climate. Yes we have had a number of record cold events in 2007, and the winter in the Northern Hemisphere is already shaping up to be colder than normal. But fortunes of weather can turn on a dime. I’d also point out that we are in a solar minimum right now and predictions of solar cycle 24’s peak range from it being very low (colder) to very high (warmer). The next few years will be telling.

Snow in Buenos Aires, July 9th, 2007

Year of global cooling

By David Deming
December 19, 2007

South America this year experienced one of its coldest winters in decades. In Buenos Aires, snow fell for the first time since the year 1918. Dozens of homeless people died from exposure. In Peru, 200 people died from the cold and thousands more became infected with respiratory diseases. Crops failed, livestock perished, and the Peruvian government declared a state of emergency.

Unexpected bitter cold swept the entire Southern Hemisphere in 2007. Johannesburg, South Africa, had the first significant snowfall in 26 years. Australia experienced the coldest June ever. In north-eastern Australia, the city of Townsville underwent the longest period of continuously cold weather since 1941. In New Zealand, the weather turned so cold that vineyards were endangered.

Last January, $1.42 billion worth of California produce was lost to a devastating five-day freeze. Thousands of agricultural employees were thrown out of work. At the supermarket, citrus prices soared. In the wake of the freeze, California Gov. Arnold Schwarzenegger asked President Bush to issue a disaster declaration for affected counties. A few months earlier, Mr. Schwarzenegger had enthusiastically signed the California Global Warming Solutions Act of 2006, a law designed to cool the climate. California Sen. Barbara Boxer continues to push for similar legislation in the U.S. Senate.

In April, a killing freeze destroyed 95 percent of South Carolina’s peach crop, and 90 percent of North Carolina’s apple harvest. At Charlotte, N.C., a record low temperature of 21 degrees Fahrenheit on April 8 was the coldest ever recorded for April, breaking a record set in 1923. On June 8, Denver recorded a new low of 31 degrees Fahrenheit. Denver’s temperature records extend back to 1872.

Recent weeks have seen the return of unusually cold conditions to the Northern Hemisphere. On Dec. 7, St. Cloud, Minn., set a new record low of minus 15 degrees Fahrenheit. On the same date, record low temperatures were also recorded in Pennsylvania and Ohio.

Extreme cold weather is occurring worldwide. On Dec. 4, in Seoul, Korea, the temperature was a record minus 5 degrees Celsius. Nov. 24, in Meacham, Ore., the minimum temperature was 12 degrees Fahrenheit colder than the previous record low set in 1952. The Canadian government warns that this winter is likely to be the coldest in 15 years. Read the rest of this entry »





U.S. Senate Report: Over 400 Prominent Scientists Disputed Man-Made Global Warming Claims in 2007

20 12 2007

U.S. Senate Report: Over 400 Prominent Scientists Disputed Man-Made Global Warming Claims in 2007 

from this link:

http://epw.senate.gov/public/index.cfm?FuseAction=Minority.SenateReport

The variety and reach of this is quite large. This is a report gathered from many independent publications, it is not one of those “Internet Petitions” which can be easily loaded up with fake names by those that seek to minimize it.

I think the gist of this is that the pronouncements of “the science is settled”, the “debate is over” and “scientific consensus” may be a bit premature.

Of course I’m sure we’ll have those that will denounce this for a variety of the usual reasons, such as the favorite “they are all employed or supported by the fossil fuel industry”.  But given the diversity on this list that will be pretty hard to prove.

For those interested in my work on the www.surfacestations.org project, this set of preliminary data posted here on 460 out of 1221 USHCN climate stations in the continental USA pretty well sums it up:

The Best Christmas Present Anybody Could Ever Have

19 12 2007

My coffee buddy, Butte County Sheriff Perry Reniff helps Alexis Dominguez exit the helicopter (Photo: Bill Husa, Chico Enterprise Record)

 Today was a good day. No, strike that, today was a GREAT day!

The saga of the Dominguez family lost in the snow looking for a Christmas tree hit home with me in a big way, because I had people from all over asking me what the weather was going to do to the search and rescue effort. I was the bearer of bad news, which I hated, because the winter storm bearing down made survival even less likely.

(Note: for national/international readers of this blog, this story unfolded in my home city and county)

Mountain weather is unforgiving. Fortunately, they knew what to do. They improvised a snow cave, wrote “HELP” in the snow, and stayed put until rescuers could find them. When they did, the relief was nation-wide.

Yes, its the best Christmas present anybody could ever have.





Study: Greenland prior eras as warm or warmer than today

18 12 2007

uc-greenland-agu-map.jpg

I was forwarded a slide show presentation done by Thomas Lowell et al of the University of Cincinnati titled: Organic Remains from the Istorvet Ice Cap, Liverpool Land, East Greenland: A Record of Late Holocene Climate Change

It was presented last week at AGU’s Greenland Climate Change Past and Present session. It has some very interesting data in it. In summary it has a report on occurrence of subfossil organic remains, with organics recovered in locations presently void of plant growth.


Picture of Istorvet organic remnants at edge of glacier melt.

The preliminary conclusion from the data collected in the field work is that presently the small ice caps at high latitudes in Greenland are retracting to locations where they were at 1000 years ago.  The presence of subfossil vegetation was found within 280 vertical meters of ice cap summit and where comparable modern assemblages do not exist. The implication seems to be that there were warmer periods in these areas prior to today, warm enough for plant growth.

According to the study, the organic material in Liverpool Land radiocarbon dates from 400 to 1015 AD. It is interesting to note that the Vikings settled in Greenland around 974 AD and the study indicates that ice cap expansion began around 1015 AD.

uc-agu-greenland-timeline.png

While the UC team that did the field work still has more work to do to reconstruct temperatures from this data, the study lends support to the idea that Greenland’s climate was warmer approximately 1000 years ago. One of the organic samples recovered at another location was dated to 910BC. This makes one wonder just how often shifts in Greenland’s climate occurs.

More study is needed, but this is certainly interesting. You can view the abstract here





Update: GOES12 is back online!

18 12 2007

After a near brush with death, GOES 12 is back up and running, our full disk image  is now 100% The loop may take some time to get synced but images are being produced from GOES 12 correctly now.





Told Ya So!

18 12 2007

As I blogged about earlier this year, Vista sucks. Now comes vindication of my views from PC World’s The 15 Biggest Tech Disappointments of 2007 unsurprisingly, Windows Vista has been rated the most disappointing product of 2007.  It’s delicious irony that this OS runs best on an Apple Macbook. See below. Maybe Steve Ballmer will finally get a clue. Heck I might even start running Apple ads on this blog just to spite him. This from a guy who used to hate Macs with a passion, but now sees OSX as a better choice than Vista, and for some users, even Windows XP.

Here is the PC World article on #1:  

#1. No Wow, No How: Windows Vista

vista.png

Five years in the making and this is the best Microsoft could do?

It’s not that Vista is awful. The integrated security and parental controls are nice, and the Aero interface is as whizzy as it gets. Searching and wireless networking are much faster and easier than under XP.

It’s just that Vista isn’t all that good. Many of the innovations the operating system was supposed to bring–like more efficient file and communications systems–got tossed overboard as Microsoft struggled to get the OS out the door, some three years after it was first promised. Despite its hefty hardware requirements, Vista is slower than XP.

When it debuted last January, incompatibilities were rampant–in part because hardware and software makers didn’t feel any urgency to revamp their products to work with the new OS. The user account controls that were supposed to make users feel safer just made them feel irritated. And at $399 ($299 upgrade) for Windows Ultimate, we couldn’t help feeling more than a little gouged.

No wonder so many users are clinging to XP like shipwrecked sailors to a life raft, while others who made the upgrade are switching back. And when the fastest Vista notebook PC World has ever tested is an Apple MacBook Pro, there’s something deeply wrong with the universe.

We have no doubt Vista will come to dominate the PC landscape, if only because it will become increasingly hard to buy a new machine that doesn’t have it pre-installed. And that’s disappointing in its own right.





One more thing to worry about

18 12 2007

While we are all recovering from the news of the terrible fate that awaits us as outlined recently in Bali, astronomers have, for the first time, witnessed a super-massive black hole hitting a nearby galaxy with a “death-star-like” beam of energy.

The story also has a video with simulations, pictures, and explanations. “The ‘death star galaxy,’ as NASA astronomers called it, could obliterate the atmospheres of planets but also trigger the birth of stars in the wake of its destructive beam. Fortunately, the cosmic violence is a safe distance from our own neck of the cosmos.”

The deadly galaxy — the largest of two in a system known as 3C321 — is aiming the high-energy jet from its center at a smaller galaxy 20,000 light-years away from it, or roughly the distance from Earth to the Milky Way’s core. Both galaxies are situated about 1.4 billion light-years away from Earth. An artist’s conception is below:

A bright spot in a NASA composite image at the top of the article reveals that the beam is striking the edge of the smaller galaxy, deflecting the spindle of energy into intergalactic space. While not a direct hit, astronomers said the consequences are frightening.

But as they say, stuff happens, entropy occurs. And, it’s a reminder that we are nothing more than a fly speck on an elephants butt in the whole grand scheme of space, time, and energy.





Climate Audit back up soon

17 12 2007

I’m getting lots of emails from worried folks about the status of the Climate Audit website.

 It’s a DNS snafu caused by closing a billing for hosting service that isn’t used anymore. I’ve already cured the problem but the trickle through of new DNS entries takes time, web-wide.

For those with Windows try this:

  1. Open a command line window or type “cmd” in the “run” box
  2. type ipconfig /flushdns  – should report that it has flushed resolver cache
  3. type ping www.climateaudit.org and if return IP address has a .124 on the end then you are good to go, if not, you’ll need to wait a couple of hours for your ISP to update DNS records
  4. if good to go, open your browser and go to website

If you own a Mac, (thx to Russ)

Mac users should go to Safari Browser and Empty Cache, then go to Utilities, select Network Utility, click on Ping and type in climateaudit.org. If ping come back .124 in the last three, the Mac Users are good to go.

Spotting Weather Stations in SFO

16 12 2007
sfo-duboce-park-weather-station-panorama-640.jpg
San Francisco’s official weather stations, new and old locations are in this photo – can you find them?

Last Thursday evening I had the pleasure of meeting up with Steve McIntyre, Steve Mosher, and “jeez” (who lives in San Francisco, and currently wishes to remain anonymous) from Climate Audit. We had dinner at Umbria in downtown SFO and talked shop about “everything under the sun”. Mostly we talked about things we’ve learned over the past year and the reactions to them. It was a great evening that I’ll always remember, and “jeez” was a superb host. My thanks to him not only for dinner but for some special help I’ll discuss later. Steve Mosher is a lot more soft spoken than his online persona would indicate, but very sharp witted, and Steve McIntyre provides great conversation and good humor. Read the rest of this entry »

From AGU – the cause of Aurora Borealis and TSI questions

15 12 2007

Scientists think they have discovered the energy source of auroras borealis and australis, the spectacular upper atmospheric color displays seen in the highest latitudes of the our planet. At the same time, this discovery raises questions about our understanding of Total Solar Irradiance (TSI).

Results were presented Tuesday at the American Geophysical Union  (AGU) meeting. NASA has a press release on their science site

New data from NASA’s Themis mission, a quintet of satellites launched this winter, found the energy comes from a stream of charged particles from the sun flowing like a current through twisted bundles of magnetic fields connecting Earth’s upper atmosphere to the sun. The energy is then abruptly released in the form of a shimmering display of lights.

Estimates of the total energy of a two-hour auroral event they studied are at five hundred thousand billion (5 x 10^14) Joules. That’s approximately equivalent to the energy of a magnitude 5.5 earthquake.

“The satellites have found evidence for magnetic ropes connecting Earth’s upper atmosphere directly to the Sun,” says Dave Sibeck, project scientist for the mission at the Goddard Space Flight Center. “We believe that solar wind particles flow in along these ropes, providing energy for geomagnetic storms and auroras.”

One of the things that has always bothered me about the claims that Total Solar Irradiance (TSI) variance can’t account for climatic changes is that it only considers the visible output of the sun, yet the sun has many mechanisms for transferring energy to the earth. Now we find another, magnetic ropes.

Our planet is bathed in the sun’s ultraviolet, solar wind, and magnetic field variances, yet these are not considered in the most common equations or modeling of earth’s total energy budget from the sun. Given that we’ve just learned something new about how the sun transfers energy to earth, I’d say that the TSI numbers that are commonly tossed about by climate modelers and their proponents are lacking in a total understanding of the sun to earth energy transfer.

To me, the fact that the suns magnetic field is linked more closely to earth now lends credence to theories like that of Henrik Svensmark, which points to an extraterrestrial driver of climate change, cosmic rays which form cloud nuclei in our atmosphere, modulated by solar variance. Given the “magnetic ropes” discovery announcement this week, I believe there are processes that transfer energy to our planet or modulate it’s energy balance that we haven’t yet discovered. In doing measurements in situ of our planets energy balance we need to look beyond just our atmosphere, because that’s the real and total in situ environment.

As Jack Horkheimer always used to say as he ended his astronomy program, ”Keep looking up!”.





Signs of a new solar cycle?

14 12 2007

From NASA:

The solar physics community is abuzz this week. No, there haven’t been any great eruptions or solar storms. The source of the excitement is a modest knot of magnetism that popped over the sun’s eastern limb on Dec. 11th, pictured below in a pair of images from the orbiting Solar and Heliospheric Observatory (SOHO).

see caption

Above: From SOHO, a UV-wavelength image of the sun and a map showing positive (white) and negative (black) magnetic polarities. The new high-latitude active region is magnetically reversed, marking it as a harbinger of a new solar cycle.

Off to AGU

13 12 2007

I’m off to San Francisco to the AGU meeting and to meetup with Steve McIntyre and others. So I won’t be posting for awhile.

I’ll have some new material over the weekend.





How not to measure temperature, part 45

10 12 2007

I’ve covered California’s temperature stations and their exposure problems extensively, now it’s time to head north to Alaska. When you think of Alaska, you think of cold, snowy, pristine remote wilderness, right? Surely there are no worries about urbanization affecting thermometers in the great white north. Well as I’ve said before, the NOAA MMTS system used to measure temperature for climate has two fatal flaws that keep it close to human influences: 1) a need for a person to read the display and write it down 2) A cable from the display to the sensor.

So it’s no surprise to find that in Cordova, AK the official NOAA thermometer (COOP Number 502173  60.55611°N -145.75306°W)  is right next to the diesel power facility and it’s outdoor transformer. The display is inside where it’s warm and can be comfortably read.

cordova_ak_labeled_520.jpg
Click for larger image - picture: John Papineau, National Weather Service, Anchorage AK

It’s not just the waste heat from power transformers nearby that can cause a bias, there’s also an air exhaust vent, and inside the building, which is known as the Orca Diesel Generation Plant is a very large diesel generator capable of providing 7 megawatts of electric power for the town of Cordova. Below is a view inside the facility from the Cordova Electric COOP web page.

It would seem a warmer than normal place, and you can see an aerial view of the power generation facility here from Google Earth.  You can also see the aerial view, the thermomter is located at the blue building to the left of the storage tanks in the foreground (click for larger images).

Of course, a temperature sensor with that sort of proximity would be measuring waste heat from electric power generation in addition to normal climate fluctuations. Below is the GISS temperature plot for this station. Note the discontinuity around 1940 due to a station move, but also notice the positive step change that begins around 1980, likely a result of the well known 1976-77 PDO (Pacific Decadal Oscillation) shift.

cordova_giss_plot.png

I wonder if power demand in Cordova has gone up in the last 20 years? The Cordova Electric Company was formed in 1978 by a town vote and this facility was completed in 1984.

One of the things that NASA GISS and other research institutions claim is that we’ve had a greater rate of warming near the higher latitudes, as seen in the map below.

ghcn_giss_250km_anom11_1951-1980.gif
Map from NASA GISS

One has to wonder though, just how much of that has to do with temperature measurements being taken in proximity to a growing human population at these locations? More on the Alaskan temperature story to follow.
