It sure seems that way. Yesterday, NWS Anchorage trumpeted these headlines:
Here is the official report. [language removed – I accidentally conflated the all-time record high with daily high -Anthony]
The stage was set by a weather event: a large high-pressure dome centered squarely over Anchorage:
Despite what climate alarmists say, it was a weather event, not a climate event.
But did the location of the temperature reading have anything to do with the new “all-time” record high in Anchorage? Quite possibly.
First, there were other records set in the area, and all of them were smack-dab under the center of that high pressure dome. It is a well-known meteorological fact that sinking air heats up:
Note that those other records are all at airport locations.
Here’s the location of the ASOS (Aviation weather station) that made the Anchorage record in Google Earth. Note the black streaks on the runway just south, that’s where the majority of planes land and put on reverse thrust and take off. Winds coming from the south will push hot jet exhaust towards the ASOS temperature sensor.
The yellow marker is the location of the ASOS weather station via Google Earth:
NW winds will be warming downslope winds from Mt. Sustina (Foehn winds). Yesterday the prevailing winds were WEST at the time of the records, but NW either side of that hour. Winds from N, NW, W, SW, and S will all transport heat from the taxiway and runway asphalt towards the temperature sensor.
Closeup view:
This image from Bing Maps via Digital Globe shows that there is construction going at the airport for that runway. Note all the construction equipment parked around the ASOS station (circled in red):
One wonders if the construction equipment might have been adding to the temperature record, like our famous Scottish Ice Cream Truck added to an “all-time” temperature record.
Here is the hourly data from July 4th:
The Government Hill station in Anchorage , about 5.6 miles away to the NE, only hit 79 about the same time on July 4th
Source: https://www.wunderground.com/dashboard/pws/KAKANCHO105/graph/2019-07-4/2019-07-4/daily
In 1969, the airport station was not sandwiched between two ashpalt heatsinks and the ASOS didn’t exist. The ASOS system didn’t come into use until the 1990s.
I think the location at the airport could have easily added a couple of degrees to the record. Same for the other airport locations of Kenai, Palmer, and King Salmon.
Airport history, note the growth:
http://www.dot.state.ak.us/anc/about/history.shtml
It sure looked a lot different before 1970. Small tower, and only one runway, as this historical photo from the FAA shows, looking west.
UPDATE: Merrill Field was the Anchorage airport in the early days of the temperature record, and now serves as a general aviation airport.. The current Anchorage airport Ted Stevens Anchorage International Airport was built in 1951.
Note the airport (Merrill field) today – a lot of asphalt and concrete:
UPDATED: {added from Wikipedia} Ted Stevens Anchorage International Airport covers an area of 4,608 acres (1,865 ha) at an elevation of 151 feet (46 m) above mean sea level. It has three runways: 7L/25R is 10,600 by 150 feet (3,231 x 46 m) with an asphalt surface; 7R/25L is 12,400 by 200 feet (3,780 x 61 m) with an asphalt/concrete surface; 15/33 is 10,960 by 150 feet (3,341 x 46 m) with an asphalt surface. For the 12-month period ending December 1, 2017, the airport had 261,961 aircraft operations, an average of 718 per day.
The Anchorage International Airport was renamed in 2000 by the Alaska Legislature to honor then long-standing U.S. Senator Ted Stevens.
UPDATED: Here is a postcard from around 1960 of the Anchorage International Airport:
Here is the airport today:
And in 1964, according to NOAA’s HOMR database, the station was moved about a mile west, probably from the tower location. Back then most small airport towers had the temperature sensor on the tower so they could computer and report the very important density altitude information.
| 1964-04-02 | 1.06 mi W |

This was probably due to the airport reconstruction due to the great Alaska Earthquake. Maybe the Earthquake had a hand in the 1969 record due to the location change and the construction.
In my view, the Anchorage airport is a false record, aided and abetted by the location of the thermometer, and a terrible place to measure for climatic records. In my view, this record reflects the growth of the airport, not climate change.
Don’t believe me? Read this recently released peer-reviewed paper which says simple things like “openness” due to obstructions contribute as much as 1 degree C: (h/t to Dr. Roger Pielke Sr.)
Microscale Warming due to Poor Ventilation at Surface Observation Stations
Abstract
Screen-level air temperature measurements at surface observation stations are influenced by local-site-scale factors. These local influences may affect global-scale climate change studies. This study investigated the influence of surface obstacles on air temperature measurements at the screen level at climate observation stations in Japan. Screen-level air temperature was measured simultaneously at two neighboring sites (<100 m apart) that differed in terms of their openness. Daytime air temperature was 0°–1°C higher at the narrower site, and theoretical analysis revealed that this warming was caused by poor ventilation. At night, poor ventilation at the narrower site caused the air temperature to be 0°–0.2°C lower, which was demonstrated experimentally and by theoretical analysis. The range of temperature changes due to site narrowing shown in this study is not negligible in climate change studies. Guidelines for site maintenance and metadata recoding were consequently proposed in terms of site openness.

It makes me wonder if that construction machinery (see above in the Bing Maps photo) was still parked around the ASOS for the July 4th holiday.
UPDATE 7/6/19 9AM PDT:
From the Anchorage Daily News: (bold mine)
Anchorage hits an official 90 degrees for the first time on record – with an asterisk
The weather service first reported that a record of 89 degrees had been reached in an hourly sampling of airport weather. The actual temperature was 89.1, but it is the weather service’s practice to round to the nearest whole number.
But because the temperature of record is collected at an airport, it is sampled more frequently than on the hour, an NWS official in Anchorage said. Upon evaluation of minute-to-minute temperatures, the weather service said, meteorologists saw that at exactly 5 p.m. the temperature spiked to 89.6 degrees before cooling back down to 87.8 five minutes later.
That my friends is either jet exhaust impacting the sensor, or wind carrying heat off the tarmac, taxiway, or runway.
Another example of a “record” due to bad siting.
Like the French heat wave last week, Montpellier airport was supposed to have broken the old record by several degrees. But the sensor is next to massive new carpark which was build about 15 years ago.
Every article I read stated unequivocally that the Arctic is MELTING !!!! Aiiiiieeeeeeeeee !!!!!! Every plant and animal in the Arctic is going to DIEEEEEEEEEEE!!!!
You mean that isn’t true?
It’s official – hot weather is proof of…man made global alarmism. Cold weather, well, hey look over there.
Global warming has vanished as a main alarmist talking point; it is now severe weather caused by … something Man has done to produce CO2. Random hot weather events get their hype, but its hurricanes, storms, floods, droughts and etc. that are whipping up the masses for them to approve of socialist schemes, insane energy policies and higher taxes. Its hysteria about “increasing extreme weather events” and “accelerating sea level rise” causing an “existential threat” to mankind that now drives CliSci propaganda.
It is an observable fact that UN IPCC climate model “projections” are not a sufficient reason to fundamentally alter our society, economy and energy systems. If you believe that they are actually sufficient for such a purpose, come right out and say so. Don’t hide behind arcane arguments related to the latest nitpicking “peer reviewed” study that uses their extreme predictions.
The entirety of CliSci is based on high ECS assumptions driving the (proven to be) inaccurate UN IPCC climate model forecasts. The misuse of unrealistically extreme and dystopian scenarios for modeling, along with fanciful ECS guesses, gives us the unbelievable projections (used as actual forecasts by propagandists) of future warming. It should be a crime for “researchers” to use UN IPCC model outputs to speculate about the demise of their chosen biota over the next 80 years or so.
Obvious siting problem.
With a thermometer up yer butt it is a sitting problem.😖
It’s takes a thinking mind to do work like this. What does that say about our climatologist friends?
Thinking mind: “This [90F temp] wouldn’t have anything to do with acres of cement and asphalt surrounding the thermometer, would it?”
PhD Climatologist mind: “No it would not”
Thinking mind: “What do record cold temperatures in 4 provinces in Canada this winter mean? Why don’t you ever cover record lows?”
PhD Climatologist mind: [sound of dropping pin]
https://twitter.com/Climatologist49/status/1146931497602936832 (scroll down)
That’s a good twitter feed, obviously and impossible always useful sorts of science settled words. “Feels like 103°” currently a couple of miles from where I live. Guess where that comes from? It would help to put normal back to average (or even mean) where it belongs and feel like to, well, I feel like I have forgotten the proper word. Weather Underground does use average and heat index for surrounding stations but champions extremes, usually hot.
How may anemometers get (un)blocked over the years? I feel like we are getting more wind recently.
Excellent icisil!
Still, half the US states’ standing high temperature records were set before 1941! Yet the “adjusted” NASA data have disappeared the Dust Bowl.
Yes, and NASA has practically disappeared the hot El Nino year of 1998.
NASA wanted to do that so they could pretend that the last few years were the “hottest years evah!”
Fortuntely, the UAH satellite chart still gives 1998 its due, showing it as warmer than any year in the 21st century except for the year 2016, which was 0.1C warmer than 1998 (a statistical tie)…
Apparently “ALL-TIME” is only 67 years. Who knew?
Most paleoclimate proxies don’t have the temporal resolution to show such “ALL-TIME” blips in the record, or even centennial blips, making them pretty useless for setting precedent.
Airport based weather stations are designed to tell your the conditions related to flights and out of the airport .
Has these area can be very different to rest of the environment you cannot use weather data from a station located somewhere else .
They are used for general weather record NOT BECAUSE THEY DO A GOOD JOB BUT BECAUSE THEY ALREADY EXIST.
In the old days of ‘uncertaining ‘ it did not matter what these locations had ‘problems ‘because its accepted as a ‘hit and miss ‘ game anywhen . That is until ‘settled science’ came along and suddenly all those problems needed to ‘go away ‘ not that anything was changed about what caused them .
Anyone who as ever worked airside could tell you hot the pans get and what ‘jet wash ‘ feels like .
For the purpose that these particular type of stations serve – determining air temperature near the runway, which can be critical information for takeoff purposes – the siting here is fine. But for general atmospheric purposes they’re obviously flawed (they’re probably going to run hot), and the people announcing these records know this, or at least they should. I’ve gotten to where I just automatically disregard any “record” temperature claim if it comes from an airport station.
Gee, Anchorage had record heat caused by a sinking air mass.
Meanwhile, Mammoth Mountain skiers and snowboarders were enjoying the still-deep snows with jumps and leaps and slaloms down the mountain. Accuweather posted a nice video about it. They won’t close the slopes until probably August, and then the next snow season will be upon them.
Weather is a strange creature. It confuses people who don’t understand that it’s constantly changing. I expect to see snow in September this year, AGAIN. Try keeping a weather diary, and shooting pictures of events like early and late snows to support things. That may prove useful some day.
Snow that Sticks all through the year is the beginning of glaciation
Sara,
It is not unknown for for the Sierra Nevada Mountains to have snow even in July.
LOYDO ? ? Where are you ?
😉 😉
Off Skiing
Here I am.
“Despite what climate alarmists say, it was a weather event, not a climate event.” Huh?
What is a “climate event” that hapens in one day? Is there such a thing? Apart from Anthony, who used that phrase? I googled it but the only reference was this below, so I guess he just made it up. http://www.thebristolbaytimes.com/article/1901extreme_lack_of_sea_ice_fall_heat_mark_2018
Given Alaska’s skyrocketing temperatures I’d be most surprised if the record maximum DIDN’T skyrocket too. So of course its part of the ongoing climate event that is the rapid warming of Alaska and the Arctic in general and that just can’t be ‘splained or doubt-mongered away as “weather”.
http://4.bp.blogspot.com/-cr0gv5jgV3k/VLK7cgieb6I/AAAAAAAADGE/qh1QyewTsvg/s1600/ANC_Ave_Ann_Temp_1916_2014.png
Somehow the definition of “skyrocketing” got downgraded by a huge amount.
Climate events can happen every day on this planet, according to the latitudes , heavy rains and hail flooding roads and railways.
Avalanches, mudslides, coming down.
Siberian forest fires in sparsely populated areas.
Fort Yukon holds the record in Alaska of 100 F in 1915.
Is this really something to get excited about?
No it’s not anything to get excited about, other than 90 degrees is unusual for the southern part of the state and so it’s notable briefly as something that happens once or twice per century. . It’s as unusual as dropping to-34 in Anchorage in the winter, although that’s a very common winter temperature for Fairbanks or Fort Yukon. It doesn’t make it unnatural in any way. BTW Fort Yukon or Fairbanks often get to 90 and above in the Summer because they’re further north, in the middle of a very large plane, and have no real darkness. It’s much easier for a stagnant air mass to situate itself in the middle of the state, between the Brooks range and the Alaska range, and with 23 hours of illumination, temperatures will go up and up when that happens. The other thing is that most people don’t realize how damn big this state is.
But the fact of the matter that no one seems to realize is that once the high pressure dome established itself over this area, it was a given that temps would end up reaching or breaking records if the dome lasted long enough. The daylight heating hours at this latitude are so long at this time of year that temperature can only go up every day as long as the dome persists. It has absolutely nothing to do with CO2.
So the question becomes: does this period of high pressure differ substantially from the period that gave us the previous record in 1969? And was such temp difference affected by the growth of the area? Can we assume that 3-5 degrees is due to UHI? I think the answer is that it’s clearly a factor, if not the factor. The Anchorage region suffered a 9.2 earthquake in 1964, still the strongest in North America and one of the strongest ever recorded. It totally flattened Anchorage, and pretty much all of South Central Alaska. I can’t imagine that all had been rebuilt 5 years later. Heck when I got here in 1992 you could still see the impacts of the earthquake. Anchorage has almost doubled in size over the last 20 years. The airport has exploded in size and traffic. The largest roads of the state (in terms of lanes) have been built around the airport. So I think we can safely assume that growth affected the temperature, as it has done in every other city in the world.
(period of record 1952-2019) The ALL-TIME high?????? So time began in Alaska in 1952??????? Who knew?
Only all time RECORD high.
Records only go back to 1952 as all daily recordings prior to 1952 were eaten by the Pet Moose
But that’s not what they say in every case: “Anchorage hit 89 degrees Thursday to break the all-time highest temperature ever recorded at the official recording station. The previous record was 85 degrees set on June 14, 1969.”
They should consider themselves as blessed, looking at the dew point temps compared to the central-midwest US. The true measure of kinetic heat in the atmosphere has to be relative humidity and the dewpoint. That’s what is keeping the Arctic from getting as cold as the alarmists desire in winter.
Everything points to water as the dominant feature of Terran climate regulation. Nothing observed (without confirmation bias applied) suggests that CO2 has played a significant role in weather and (over the 30 year term) climate. The effects of ENSO are most apparent and indisputable.
The fact that we are enjoying an optimal temperature period accompanied by a beneficial rise in a trace gas necessary for all life on the planet should not be overshadowed by provably false allegations of atmospheric overabundance.
It is amazing there are so few all-time record temperature highs for cities throughout the world these days, given that temperature records go back for only decades rather than centuries, and given that there are thousands of cities throughout the world.
Northern Hemisphere Arctic Amplification is a two-edged sword for the climate hucksters; cold periods are amplified as well as hot periods. CliSci uses the current hot period and compares it to the post-1940 to early 1970 cold period, meanwhile disappearing the past hot period of the 1920’s and ’30’s. And “peer review” lets them get away with it.
Always watch for the sleight of hand. CliSci practitioners are propagandists; they have gotten their way by pretending to be disinterested scientists. Eventually, though, most people will begin to use the common sense they currently use in reviewing advertisements, especially when the coming tax hikes and price increases hit. But there will always be the suckers.
It seems to be too late for the EU; the socialists have taken over. I fear it might be too late for the U.S. There is, however, always hope; that pesky American Constitution seems to sometimes get in the way of the schemers.
Dave Fair,
You said, “… cold periods are amplified as well as hot periods.” How and why is that? Are you confusing unsupported claims of increasing extreme weather with that of a warming climate? My impression is that Arctic Amplification happens because it is a region with typically low humidity, and therefore, increasing CO2 has a disproportionate effect on nighttime and Winter warming. Why would cold periods be amplified?
I just returned from Anchorage and Soldotna a day ago. The car thermometer was 85 on Wednesday on blacktop. I could see the airport being warming due to all the buildings around. Good news though, Wxit glacier has not disappeared saw it with my own two eyes.
https://www.google.com/search?q=Wxit+glacier+&client=ms-android-
Of course Government Hill is going to be cooler, with water immediately west and northwest of it. Note the low temperature at Government Hill was 61 F, and it was 59 F at Anchorage. (I had to look that up myself.) This looks like the main reason Anchorage International Airport got so much warmer was because it was inland. Note that urban effects normally warm nighttime low temperatures more than daytime high temperatures.
Anchorage International is on the coast . See the photo in wiki “Ted Stevens International Airport.”
Yes thanks, language updated and additional photos added.
High pressure, no wind; everything manmade just sits and bakes. The natural heat sink of Cook Inlet helps cool areas nearby.
Ted Stevens AIA has water directly adjacent to the west and north. This actual data collection site is surrounded by asphalt or recently bared earth on 4 sides and is adjacent to an extremely busy runway and taxiway. Why is anchorage so busy? It is a primary refueling point for air freight between the lower 48 and Asia. The big jets boil into and right back out of Anchorage night and day.
Government Hill, while it is near the water also, and has a few green spots, is also surrounded by the Port of Anchorage, the railroad yard, and sprawling Elmendorf Air Force Base. If there is a 10 degree F delta between GH and Ted Stevens airport a few miles away, then that would be a huge red flag.
The airport in the article’s final two pictures is the one downtown, Merrill Field, not the much larger Stevens Anchorage International where the 90-degree temperature record was recorded.
Note the update.
I think there is enough evidence to suggest that the “Global Warming” scare was not started in 1988 in Washington DC by Jame Hansen but in 1903 at Kitty Hawk, inadvertently, by the Wright Brothers.
Merrill airfield still exits today and is in regular use. It used to be Anchorages international airport until the one currently referenced in this article was built. So, they are two airports. Not one that expanded in size.
Don’t forget the heat all those heavies burning rubber on landing.
https://www.flightradar24.com/UPS81/212a17f7
There has also been a low pressure area in the nearby Pacific, feeding warm air from the South, possibly boosted by flows around hurricane Barbara further South-East.
Don’t know about Anchorage, but here in Palmer we are having a heat wave. Record breaking? As others have pointed out it varies depending on where it is measured and who really remembers the previous record.
Recent readings from the Wonderground weather site
(https://www.wunderground.com/weather/us/ak/palmer)
show a variance of as much as 5 degrees from the main reading at the airport, to others in the area listed further below on their website. I am not sure where the monitor is located at the airport, but they have recently extended part of the runway, but there is not a lot of other construction going on. The other sites could be lower if they are located in slightly higher elevations. At any rate it’s certainly impossible to come up with an “average” temperature for the region at any point in time.
The main point to remember in Alaska is how new everything is compared to the rest of the U.S. Who knows what the temperature records really were and exactly where they were taken 50 to 100 years ago?
The Ted Stevens Airport contains a fascinating photo display showing the primitive state of the fields in the ’50’s and how it developed to what it is today with the second biggest air freight facility in the world with the largest float plane base in the world next to it.
Palmer was settled as a pioneer farm project during the great depression in the 1930’s as part of the Matanuska Colony project by the U.S. government at the time and didn’t become a city until 1950. The beginning of the airport didn’t start until 1945 and took several years after that before it became more than an improved “Bush Plane” strip.
On top of all that, most urban residents have arrived here only in the last fifty years or so and wouldn’t have much older weather history with which to relate so they buy into any “warming” hysteria. Finally the press here is fully subscribed to the “human caused global warming” idea as is most of our media these days.
Have we really broken records? Who really knows?
Fergie
Palmer, Alaska
As a point of clarification, Merrill Field, which is shown in two photos above, is a general aviation airport across town from Anchorage International Airport. It was the official weather station for Anchorage but only from 1943 to 1952. All the official temperatures since 1952 are from the International Airport. Also, the north/south runway at the International Airport is currently closed for refurbishment and all take offs and landings are on the two east/west runways.
Can someone please tell me what’s special about 1943? Station 500285 (Merrill Field) has “period of record” starting in 1914 and it seems to have become a regular weather station in 1931. I note:
https://wrcc.dri.edu/cgi-bin/cliMAIN.pl?ak0285
(Station metadata starts with the start of 1931)
Prior to 1943 the observing site was located about 1.5 miles west of the current ASOS site near the west end of the runway at Merrill Field. HOMR has metadata back to 1914, click the LOCATION DATA tab for more:
https://www.ncdc.noaa.gov/homr/#ncdcstnid=20022052&tab=LOCATIONS
From the article: “The stage was set by a weather event: a large high-pressure dome centered squarely over Anchorage”
That’ll do it. That’s all that is required to get very high temperatures on the ground. No CO2 necessary.
“I think the location at the airport could have easily added a couple of degrees to the record. Same for the other airport locations of Kenai, Palmer, and King Salmon.”
Well, it’s the same old story of maybe jet exhausts, or construction equipment, or whatever. But that is four airports, nearby, varying amounts of traffic and circumstances, all reporting from 88 to 90 °F. Did all these special circumstances also apply to all of them? Or could it just have been that the temperature was as they measured in agreement?
Yep, Nick, absolutely. Why not? If the thermometers are sited in the same way as the one at Anchorage Airport, why not?
My impression is that airport thermometers try to measure the temperature that aircraft will encounter on the runway when taking off. That, I believe, is what pilots need to know in order to compute their maximum takeoff weight. I sure could be wrong about that. I once knew a bit about tracking aircraft, but I know next to nothing about flight or airport operations.
Remember, Anthony also said that there was a big dome of high pressure in the area yesterday. Uh, airport or no airport, that is more like ordinary weather and has little to do with the presence of CO2. Unless you are some kind of genius that can tie everything in individual weather events to all of that. You’re a smart guy, Nick, but I don’t think you are THAT kind of “genius.”
Yes, hot days are weather events. But weather, domes etc happen year after year. Planes come and go. But this was 4°F higher than anything measured before at Anchorage, planes domes and all.
Weather domes happen all the time, but they happen different places every time.
Planes come and go, but as the airport gets bigger, more of them come and go than in the past.
Nick, give up before you lose what’s left of your credibility.
A continuing problem with the debate is the meaningless terms used having many meanings to try and prove a single meaningful point
“…than ever measured before”
“Man made”
“climate change”
I’m just a lawyer but if the debate term used is overbroad, vague with many possible meanings…meaningful debate is not possible.and also very natural to be skeptical of those trying to overstate using such terminology
Nick, that’s incorrect. Hot high pressure domes do not happen every day in Alaska, especially in South Central, I can tell you that from 30 years of personal experience that this is the first such dome I have seen here. They do happen further north in the Tenana valley, Fairbanks and in the center of what is the largest state in the US, but they are very unusual further south due to many factors. Still a weather event though
Imagine that, all 4 airports have runways and jets landing and taking off.
Will the wonders of modern science never cease?
And yes, all 4 were under the same high pressure dome at the same time.
Perhaps if you were to take time and actually read the article instead of leaping to defend your pay check, you wouldn’t make so many silly mistakes.
The question is whether the temperatures recorded were representative, not the meteorology.
I’m not convinced the Kenai reading was at an airport.
So the snark you posted, was not the snark you meant to post?
Or are you just trying to hide your embarrassment again?
My question? Why does NWS refuse, adamantly, to place monitoring stations 20-25 miles outside major metropolitan areas? Sam’s Club and Costco can sell them the needed equipment at bargain prices and they can start collecting legitimate data nearly instantaneously. Well, there is the time it takes to buy the items and then install them near homes that have wifi, after that it is instantaneous. Why, I bet there are government buildings with continuous wifi within that 20-25 radius that people piggyback on all the time! Its like some sort of “network” or something.
