Where Do They Put the Thermometer, When They Measure the Temperature of the Earth?

BULLSHIT IN THE NEWS link

Issues & Insights identifies the key flaw in the Alarmist narrative.

The United Nation’s Intergovernmental Panel on Climate Change is quite certain Earth will be in trouble if the global temperature exceeds pre-industrial levels by 1.5 degrees Celsius or more. But how can anyone know? According to university research, “global temperature” is a meaningless concept.

“Discussions on global warming often refer to ‘global temperature.’ Yet the concept is thermodynamically as well as mathematically an impossibility,” says Science Daily, paraphrasing Bjarne Andresen, a professor at the University of Copenhagen’s Niels Bohr Institute, one of three authors of a paper questioning the “validity of a global temperature.”

Science Daily explains how the “global temperature” is determined.

“The temperature obtained by collecting measurements of air temperatures at a large number of measuring stations around the globe, weighing them according to the area they represent, and then calculating the yearly average according to the usual method of adding all values and dividing by the number of points.”

But a “temperature can be defined only for a homogeneous system,” says Andresen. The climate is not regulated by a single temperature. Instead, “differences of temperatures drive the processes and create the storms, sea currents, thunder, etc. which make up the climate”.

While it’s “possible to treat temperature statistically locally,” says Science Daily, “it is meaningless to talk about a global temperature for Earth. The globe consists of a huge number of components which one cannot just add up and average. That would correspond to calculating the average phone number in the phone book. That is meaningless.”

There are two ways to measure temperature: geometrically and mathematically. They can produce a large enough difference to show a four-degree gap, which is sufficient to drive “all the thermodynamic processes which create storms, thunder, sea currents, etc.,” according to Science Daily.

So if global temperature is unknowable, how can the IPCC and the entire industry of alarmists and activists be so sure there exists a threshold we cannot pass? Of course the IPCC says it knows the unknowable. In its latest report, released this month, it yet again maintained that the global temperature must “kept to well below 2º C, if not 1.5º C” above pre-industrial levels to avoid disaster.

A few years after the University of Copenhagen report was published, University of Guelph economist Ross McKitrick, one of the report’s authors, noted in another paper that “number of weather stations providing data . . . plunged in 1990 and again in 2005. The sample size has fallen by over 75% from its peak in the early 1970s, and is now smaller than at any time since 1919.”

“There are serious quality problems in the surface temperature data sets that call into question whether the global temperature history, especially over land, can be considered both continuous and precise. Users should be aware of these limitations, especially in policy-sensitive applications.”

Precisely 5 of NOAA’s temperature sensors meet their own quality standards for placement. Five.

They are actively refusing requests to relocate weather sensors by the locals who monitor and maintain them.

Phoenix has just broken a record for heat. 24 days in a row at a temperature above 110 in July. It is real, but… The temp was carefully chosen to break the record. We have had 116 days too but they didn’t chose 116 degrees, they chose 110 degrees because it will result in “record breaking heat”. In reality it is just Phoenix in the Summer. Yes it is hotter than average (another trick since 50% of any day will be hotter than average and the other 50% will be colder than average). But it makes great headlines. The truth is that this is another el nino year where the jet stream does it’s thing and makes some places colder and wetter and other places hotter and dryer than the la nina does. Happens cyclical and the news cyclically makes a big deal about it as though it has never happened before.

Another trick they use is some place in the U.S. (or the world) will break a record for hot, dry, cold, wet every year, every month, even every day. So they focus on that like a laser and the naive suck it up like it’s Bud Light. But pretty much the weather is just the weather. Sometimes a little hotter, colder, wetter, drier. windier, stagnant air or whatever. Ignore it tomorrow or next week or next month it will be different.

Where do they put the thermometer? If it’s a rectal thermometer, Washington, DC would be a good choice. Or San Francisco.

The most likely location for a weather station is adjacent to a blacktop parking lot…go figure.
