Global Asphalt Warming

The airport at Toulouse, France has been warming steadily since 1980. BLAGNACAEROP.TOUL_FR_AverageMeanTemperatureAnomaly_Jan_Dec_1928_2016

What could possibly go wrong with this thermometer placement?

    Oh Steve, stop being so silly, NOAA/NCDC take all of that into account. Your fears are misplaced. Here’s the link that tells you what they do:

    https://www.ncdc.noaa.gov/oa/climate/research/ushcn/ushcn.html

    They say:

    The final adjustment is for an urban warming bias which uses the regression approach outlined in Karl, et al. (1988). The result of this adjustment is the “final” version of the data. Details on the urban warming adjustment are available in “Urbanization: Its Detection and Effect in the United States Climate Record” by Karl. T.R., et al., 1988, Journal of Climate 1:1099-1123.

    Here’s the breakdown of the adjustments:

    Here’s the final result:

    Some sort conspiracy to lower past temperatures increase recent ones in order to meet some sort of political agenda is all in your imagination. You really do need to get some help.

    By the way, how’s that book coming along?

    • Quo Vadis says:

      Where’s the adjustment for a thermometer in a grass field surrounded by asphalt? Because that’s what Blagnac is.🙂
      Why do I think they consider this thermometer in a grass field(cooler adjusted warmer) so when it shows up warmer because IT’S SURROUNDED BY ASLPHALT they adjust it even higher because, duh, it’s in a “grass field” as anyone can see.

      Lies, Damn Lies and then there’s NOAA/NDCD

      • Scott Allen says:

        What about altitude adjustment, geographic location and number of stations.
        Higher elevation have cooler readings, there are fewer of these high altitude station.
        There are places that the nearest station could be 400 miles away, (there is 1 station for Greenland and less than 20 station in the antarctic. (The geographical small state of New Jersey has 15).
        Thus the over representative of lower altitude, nearer population centers, which effects the average,mean and medium temperature.
        NASA back fills data when data is missing, this might be a reasonable adjustment on station less than 100 miles apart, but what about station that is 400 miles apart.
        Any accountant would probably loose their job if they kept records and made up data (and call them facts) the way NASA/NOAA does.
        None of those are adjusted in the website Steve case cites.

      Steve Case, giving us the “Urbanization…….” paper by Karl, et al. makes my day (LOL) . He and his buddies gave us the revised way to measure ocean temperature not so long ago. Whatever would we do without his research? (Maybe have more dollars available for genuine sciemce?)

    • Quo Vadis says:

      One more thing Steve,

      Given the possibility for error when using thermostats in grass fields, on asphalt, adjacent to air conditioning units in front of concrete walls facing South West in Arizona (I’m not making that one up either) have you ever thought there could be a better more objective, error free way of taking the Earth’s temperature? Say use, oh I don’t know, Satellites to measure a giant swaths of Earth’s atmosphere free of said air conditioning units?

      ;-)………..I’ll show myself out……

    When i was a child, I would hold the thermometer under hot water to raise my measured temp. in order to miss school…my mother caught on quickly, as my temps. were off the charts…

    • I tried the same thing with my grandmother. I remember how I managed to pull the thermometer out of the water with what I thought was reasonable fever. When I proudly handed her the thermometer, she just nodded and re-measured two more times without leaving the room.

      I was in school on time.

      • RAH says:

        My Grandmother took another approach. She let me stay home but made sure I stayed in bed all day. It was a very long day.

        • Anytime my Grandmother could establish my body temperature with reasonable certainty—verifying the plausibility of her measurements by placing her hand on my forehead—she used the same stay-in-bed method.

          Smothered with a heavy comforter up to my chin, forced to drink warm liquids and drenched in sweat, I learned my lesson about the lesser of two evils.

        • stephen says:

          …indeed, it became increasingly worse as the school day ended, and miraculous recoveries were not permitted.

  3. Latitude says:

    I think there’s more to it than just the obvious…
    You would see huge step changes if it was just the asphalt, not an increasing slope.

    yes, most of that slope is adjustments….
    …but I think gradually cleaning up air quality has a little to do with it too

    • Growing city. Growing traffic. growing airport traffic.

      • Latitude says:

        dunno….you have to have the asphalt before you have the growth….that much asphalt at one time…I would think you would see a huge spike

        • Jason Calley says:

          Hey Latitude! “.that much asphalt at one time…”

          Is there some reason to think that ALL of the asphalt appeared at the same time? Don’t most airports grow in phases over time?

        • gator69 says:

          A really great paper on UHI (that I have misplaced) showed that cities have concentric domes of heat. The larger the city, the larger the temperature increase at its epicenter. So a weather staion in a city will see gradually rising temperatures as the city expands.

      • bleakhouses says:

        I checked out airport traffic, flights that is, and they are down over the last 5 years at least. That doesnt account for whether or not the actual planes being flown themselves are bigger local heat producers though.

        • Scott allen says:

          Actual if you look you will see a spike in the war years (Germans use of the air port) then a drop off after the war, until it was turn over for civilian use.
          The official website details a little about up grades to the facilities which corresponds to an increase in the temps, it even shows the drop in temps during the down turn in 2009 in the economy.

          If there was better info on exact dates and improvements around the station a more exacting error in reporting could be made.

    • Dave N says:

      Without any reference to a specific comment, here’s a history:

      • Latitude says:

        Dave, thanks..that’s exactly what I was looking for.
        I compared additions to the airfield with the temperature chart.
        Each time, taxiway built, runway extended, new runway built, etc…
        ….there is no step change in the temp record….which it should..
        in most of the instances, the temp actually went down

        Using this example only……..you can say that all of the temp increase was the result of adjustments to the temp record

        • Scott Allen says:

          Here is a bigger map of the placement of the weather station.
          http://www.maplandia.com/france/airports/toulouse-blagnac-airport/#map
          You can see that they built up around the station, It was moved to its present location in 1965. But at that time was located at the end of runway R140, (you can see the “old ” runway R140 to the right top of the weather station on the satellite view.)
          I would not expect to see a sharp rise in temperatures as construction would take time to complete but a more gradual increase as indicated by the graph, you would also have to factor in economic consideration (air traffic patterns, encrease ridership, air tonnage etc.)
          I agree with you on the tempature adjustments, but the failure to move this station is actually a hazard to air safety.

      • bleakhouses says:

        massive growth in the 1990s.

  4. Marsh says:

    Asphalt Warming is one thing ; we should also factor in the influence there would be from any operation of Jet Engines nearby. Burning fuel & air, generally increases temperatures along with transferring the surface heat ( to where it’s recorded ). For devout AGW followers, it’s a win, win
    situation ; just don’t tell them about recording the CO2…

    On William Gray, cannot get that thread to come up.
    Sad, for all of us that we will never have had the great opportunity you, author of ‘Real Science’ have had.to know him
    Fortunately, we have all benefited in unknowing ways from his endeavors.

    Something wacky is going on with sea ice. Maybe a large chunk of ice is in its gelatinous goo phase that can’t be determined. The horror!

    Don’t it always seem to go
    That you don’t know what you’ve got til its gone
    They paved paradise
    And put up a parking lot

    Was the Roman climate optimum manmade because of bathing habits?

    According to Sheldon Judson, in the 2nd century BC the rate of soil erosion in Latium increased ten times, which is associated with the increased number of settlements in south Etruria.[14] Additionally, from the foundation of Rome until possibly 165 AD Romans deforested huge areas for arable land.[17] In 61 AD Seneca the Younger described the high level of air pollution in Rome, which was associated with the extensive wood burning for fuel.[14]

    I did a little more digging – and The passenger count went from 1 Million in 1977 to three million in 1990..:what could go wrong?

    1977 : A million passengers: Blagnac 1 was saturated. (B2_travaux)
    April 1978 : Under Claude Duffour’s leadership, the CCIT opened a new terminal – Blagnac 2, based 800m away from Blagnac 1. The Transport Minister, Joël le Theule, attended the inauguration. (B2_1978)
    1990 : Three million passengers.

    More planes, more buildings, more jet exhaust, less air movement, new asphalt and more of it. The list goes on. If global warming was actually a problem (It isn’t) It could be fixed by taking the massive amount of money wasted in ridiculous studies and applying it to the problem.
