Warming near Coal Plants

I was learning some Python over the weekend, and then afterwards decided to go for a jog at my favorite spot. As I was jogging, I thought about finding out what the temperature trend at this location was by extracting and plotting it with Python. This site seems to offer the best local 4km data for the continental US.

My first Python program:

import requests as req
import numpy as np
import matplotlib.pyplot as mp

loc = {
	'spares': '4km', 'call': 'pp/yearly_timeseries', 'proc': 'gridserv', 'units': 'si',
	'stats': 'tmean', 'start': '1895', 'end': '2019', 'lon': '-84.3922', 'lat': '34.0000'
}

res = req.post('https://prism.oregonstate.edu/explorer/dataexplorer/rpc.php', data=loc)

tmean = res.json()['result']['data']['tmean']

y = np.array(tmean)
x = np.arange(1895,2020)
mp.plot(x,y)
m, b = np.polyfit(x, y, 1)
mp.plot(x, m*x+b)

mp.tight_layout()
mp.savefig('loc.png')

Result:

Azalea Park, Roswell, GA

Well look at that: no warming where I like to jog. How about downtowns of some big cities?

OK. Definitely warming here.

Then I had a great idea. What if I chose spots with coal plants?

I got a list of the top 20 coal plants in the USA from here.

Results:

Bowden               -0.0076
Scherer              -0.0084
Gibson               -0.0098

Jeffrey              -0.0062
Gaston               -0.0057

Units are degrees Celcius per year, based off the linear regression.

Only 3 out of 20 coal plant locations experienced warming in the last century. 85% had cooling!

I suspect this fact will not cause climate alarmists to pause and think for one second.

What do skeptics think?

  1. So where’s the ghg effect? CO2 concentrations at these locations should be relatively higher and thus warmer – if the theory is true.

        1. Sure. Local temperatures trends can vary with or without changes to CO2 levels, right?

          It follows that the locations that cooled may have cooled even more if not for elevated CO2. Or not.

          No way to tell for sure because we can’t compare the observed trends with what the trends would have been had CO2 remained at 1920 levels.

        4. And ALL engineers do not place CO2 between panes of glass to help keep your windows “trap heat”, because the result is: COOLING.

          You’re suggesting that 85% of places with high concentrations of CO2 (Coal Plants) were going to cool anyway? Don’t you find the odds low for that and this hypothesis self-serving?

          Tell me, when greenhouse operators pump CO2 into their warehouse, how much does the temperature go up?

          Surely such evidence would be useful to the AGW narrative. So where is it? Please think about it.

        5. – Double paned windows are intended to reduce conduction, not trap heat.

          – Off hand, I would have expected around 50% of the coal plant locations to have a cooling trend – in line with the lack of warming over the general area:

          I’m guessing most of the plants are in rural areas, where the UHI has had less impact than the nearby urban – perhaps helping explain the 85%

          BTW, it would be interesting to see a time series of CO2 levels near the coal plant’s in question compared to the county or state average. Maybe a significant difference, maybe not.

          – The glass in a greenhouse already acts like CO2. Allows visible in but absorbs the infrared emitted from other surfaces. More importantly though, the greenhouse is mostly warmed by preventing free convection, like a car in the sun with the windows rolled up. You should know this is different physics than the atmospheric GHE.

        6. “reducing conduction” is not “trapping heat”? That only goes for radiation? Strange how that works! Anyway, CO2 causes cooling when placed inside double window layer.

          Wait, so CO2 won’t warm a greenhouse because of the glass layer? That’s not in the theoretical model of GHGs. In that model there both a “glass” layer and absorbtivity between. Same as I’m talking about here.

        7. I should clarify this statement,

          “Double paned windows are intended to reduce conduction, not trap heat.”

          I was referring to the choice of gas, often Argon, used inside the two panes of glass. Argon is chosen mainly for its low conductivity, not for its ability to trap heat.

          My thinking is the warming would be negligible and hard to notice.

          Think about it – CO2 concentration is measured in ppm, this compared to what a solid surface like glass would be able to absorb.

          And as mentioned, the lack of convection is the bigger player, dwarfing the warming effects of CO2 even more.

          Another problem is the potential lack of a significant lapse rate within the greenhouse (for various reasons). No lapse rate – no GHE if I understand correctly.

          “Why 50%? In your map negative is gray, not white. Look again. I feel your confusing white and gray.”

          Even though the white indicates no change, most locations will have either a warming or cooling trend if the value is taken to the nearest one hundredth. Guessing 50/50 as a ballpark.

          “No lapse rate – no GHE if I understand correctly.”
          Fair enough, that does logically follow from the math …
          But, it is also claimed that GHGs creates the lapse rate!

          “compared to what a solid surface like glass would be able to absorb.”
          But what does GHG math show? That you can stack all the varying density of air, and have its GHGs form average LAYERS. Without those LAYERS, there is no GHG math warming!

          Without a LAYER splitting IR beams, there is no GH effect.

          What does the glass provide? An IR beam splitter. Half goes up half goes down.

          But then when a beam splitter (glass) is provided, you say “My thinking is the warming would be negligible and hard to notice.”

          Do you now see why scientists are skeptical?

          – Ok, I’ll take your word for it regarding the white/grey issue, even though no discernible difference on my mobile device.

          – What you and the author of the article are doing, probably without realizing it, is constructing a strawman argument.

          As an analogy, imagine someone who’s convinced a blanket can’t really make you warmer, and to “prove” it, he sets a thermometer on a large rock and then covers the rock and thermometer with the blanket.

          “Look. if what you say about blankets is true, then the rock should have heated up, but as you can see the temperature is unchanged! Experiment proves I’m right.”

          You have read that CO2 is not the best fill for a centimeters wide thermal barrier (panes of glass separating two air filled spaces – the inside and outside of a house or building), and have taken this as proof that CO2 cannot possibly be a thermal barrier to infrared moving from Earth’s surface to the vacuum of space.

          A simpleton’s assumption, with little or no consideration for the vastly different scenarios – just like the guy with the rock and blanket.

          At best, you warm the blanket.

          As the distance between glass was separated, more cooling resulted. At what distance do you suggest CO2 should warm by trapping RADIATION?

          The two layers of glass is like the surface and TOA. According to GH theory, CO2 in between should warm by reducing OLR at TOA.

          Guess what … there’s a temperature difference between inside and outside of window. It doesn’t matter if outside is not as cold as space, radiation can still go there.

          According to GH math … radiation should overwhelm conduction. Air conduction is pitiful compared to radiation.

          Again, a blatant attempt to not allow any experiment to verify or falsify theory. We have one Earth, one Venus, and no experiment can verify that GHGs make it hotter. None.

          I think I can design an experiment that NASA, ESA, etc can perform in space for very few $$$. Will they? Did they? Would they? Use your brain.

          They will not do it, because the results predicted by GH theory are false, and they don’t want to look bad.

          But my understanding is that radiative heat transfer was already greatly reduced because the bottom pane had a low emissivity coating. This negated much of CO2’s value.

          At the same time the greater weight on convective transfer exploited CO2’s weakness – low viscosity.

          That’s the best I can come up with anyway. Thoughts?

  4. Actually, the greenhouse effect is only said to work if you have an atmosphere with a lapse rate. No lapse rate, no greenhouse effect. William Happer et al. “Methane and Climate”, 2019. I believe the effect (if existent) is only theoretical. The myriad of other processes in the atmosphere will respond, and nobody can know that the net result is warming. Only guesswork. From 1941 to 1970 the temperature dropped along with exponentially rising co2-concentration.

      Nice article (mostly). Time will tell if the lukewarmers are right. I don’t really care one way or another, other than my ego would be bruised for betting against them.
      The science is interesting regardless.

      For Zoe, who likes to pretend that people from the “hard” sciences don’t believe in the GHE,

      “So, the wavelength of thermal radiation is 10 to 20 times longer than the wavelengths of sunlight. It turns out that the sun’s energy can get through the Earth’s atmosphere very easily. So essentially all sunlight or at least 90 percent, if there are no clouds, gets to the surface and warms it. But radiation cooling of the surface is less efficient because various greenhouse gases (most importantly water vapor, which is shown as the third panel down, and CO2, which is the fourth panel down) intercept a lot of that radiation and keep it from freely escaping to space. This keeps Earth’s surface temperature warmer than it would be (by about 20 or 30 degrees). The Earth would be an ice cube if it were not for water vapor and CO2.”

        1. When it comes to outgoing longwave radiation and the “co2-ditch” as a proof, here is what Claes Johnson has to say:

          “The spectrum in the ditch with it’s flat bottom at 220 K, is constructed in a two-step procedure:

          1. Identification of a line spectrum from the presence of CO2 (Hitran, interferometer).

          2. Translation of the line spectrum to a continuous spectrum defining atmospheric irradiance (Modtran modeling).

          Step 1 can be performed as direct physical measurement (as shown in Radiation of Solid vs Gas), while Step 2 is based on a model of spectral line broadening which determines the irradiance supposedly resulting from the line spectrum.

          The scientific basis of CO2 alarmism thus rests on a mathematical model of broadening of the line spectrum of the trace gas CO2 and the mathematical model is very simple as it describes the line broadening in terms of the parameter p x L where p is the partial pressure of CO2 and L is the path length.

          Classical experiments by Hottel and Leckner concern the case p ~ 1 bar and L ~ 1 m, while for atmospheric CO2 warming p ~ 0.0001 bar and L ~ 10000 m, to which direct extrapolation may not be possible.

          The net result is that CO2 alarmism is based on a simple mathematical model without direct experimental support and thus is ready to collapse once this fact becomes known and acknowledged, first by climate skeptics then by the general public and finally by CO2 alarmists.”

          As you say, Zoe – no direct experimental support, or “hard science”, if we are to believe Claes Johnson.

          2) 1880 – 2020 with CO2 rising to 415 ppm.

          Then we could make a direct comparison and there would be little room for debate.

          Obviously not possible so we’re stuck with models and uncertainty. It is what it is.

          OTOH, a recent study claims to have found direct evidence. Behind a paywall and probably over my head anyway so I have no comment.
