Proof Climate Data is Bad

Timothy Birdnow

Take a look at this.

This table gives us the climate data for the St. Louis metropolitan area. It cites three separate data sets from the three area temperature stations. You will note a major difference in the three; one is done deep in the city at the St. Louis Science Center, the second is the official temperature station at Lambert St. Louis International Airport in north St. Louis County, and the third is a dataset from Spirit of St. Louis Airport located rather farther out in Chesterfield in St. Louis County (in the Missouri River bottomland.)

Clearly, the official station at Lambert is experiencing the urban heat island effect. The temperature at Spirit is 1.5 degrees cooler on average than at Lambert. This is a result of a much lower night average of 3 degrees, a classic signiature of the urban heat island.

Why is this important? Because the official temperature at Lambert is what is used to calculate the overall temperature of Missouri. Lambert, along with the station at Columbia Regional Airport, Kansas City International, and at the Springfield airport, etc. are all subject to the urban heat island effect, and all are used to make the official calculations of statewide temperatures.

Remember, to determine the state's temperatures climate scientists and meteorologists take an average from these datasets. If you are to Trying to determine the temperature of, say, Warrenton Mo. you will average the flawed St. Louis data with the also flawed Columbia data. But Warrenton is likely much cooler.

The point is, we don't have any real idea of what the actual statewide temperature really is, and can't determine that using stations inside of artificially warm areas.

Look, the city of St. Louis, where I hang my hat, gets very little snow in winter. That is because St. Louis sits in a river valley, with two major rivers coming together just north of the city and a fairly large river (the Meramec) just south of the city. Meanwhile you have a lot of industry and residences pumping out heat, and plenty of blacktop absorbing heat and releasing it slowly at night. The result can be see in winter, when snowstorms are pushed either well north of or well south of the metropolitan area. When the rest of the state gets buried by blizzards St. Louis gets just an inch or so of snow.

That is partly a function of geography but also a result of the urban heat island effect.

The way temperature is calculated these days is rather like calculating river levels after a flood; they start with an inflated baseline. I would say this was just poor data, but the fact is it is used to prove the global warming theory. And nobody ever tries to fix the problem.

Which means it is intentional. The National Weather Service knows they are getting bad data but are more interested in promoting a theory than in getting accurate data.

1 And of course the same shenanigans are going on all over the U.S., not to mention the world. One reason, as you say, is because it helps push the narrative. Another reason is that it's easier for the "scientists" to drive, ride or even (sometimes) walk to the monitoring stations if they're closer to their own offices than, say, out in the country away from the heat islands closer to more realistic temperatures.

2 Sure, Dana; the airport is great when a scientist wants to jet to the next international conference. But are we getting accurate results? 

Anthony Watts did a survey of U.S. temperature stations and found a ridiculous situation with so many of them. Visit www.surfacestations.org for more.

3 You wouldn't want to run your Tesla out of juice traveling to all the stations in your jurisdiction, of course, when making your periodic temperature reports, now, would you? How long does it take to recharge one of those when stopping at a local watering hole?

Which reminds me: The California coastal elites are certainly blessing the day they bought their Teslas as they sit home unable to charge them during PG&E's blackouts -- unless, that is, they bought diesel chargers from Lowe's. I'm wondering what Gavin-Boy Newsom's percentage for a re-up are right about now. Meanwhile, former Gov. Moonbeam is looking like a conservative, through no efforts of his own.

4 Speaking of ex Gov. Moonbeam, he recently came out blaming Trump for the problem!  I kid you not.
