What, oh what, could cause night temperature lows to be rising over time?
Remember when you trotted out warmer nighttime lows to answer my evidence that summer high temperatures aren't getting hotter? What could cause that?
The Easiest Way to Stop Rising Temperatures
If we assume that temperatures really are rising, and then take a larger leap and assume that this is a problem, the solution isn’t for Big Government to use draconian levels of taxation and regulation to dramatically lower our standard of living. An easier approach would be to move the sensors away from the concrete and asphalt:
A new study from [US Geological Survey] by Keven Gallo and George Xian verifies what we’ve already learned and published on via the Surface Stations project; that concrete and asphalt (aka impervious surfaces) have increased near weather stations that are used to monitor climate. …
What is most important about this paper is that it quantifies the percentage of stations that have had increased amounts of impervious surface area getting closer to the stations. As I have long since maintained, such things act as heat sinks, which increase the night-time temperature when they release the stored energy from the sun that was absorbed during the day as infrared, warming the air near the thermometer, and thus biasing the minimum temperature upwards.
Anyone who has spent a summer in Phoenix, where temperatures often fail to fall below 90° at night, knows all about the heat sink effect.
In this study, they have observed over 32% of the [US Historical Climatology Network] stations exhibited an increase in impervious surface area of =20% between 2001 and 2011. When the 1000 m radius associated with each station was examined, over 52% (over 600) of the stations exhibited an increase in [impervious surface area] of =20% within at least 1% of the grid cells within that radius.
[ That's just over 10 years. ] The government claims that it adjusts data to correct for the heat sink effect. This is an admission that the data presented to us at our own expense has been manipulated. If accurate readings advanced The Agenda, bureaucrats wouldn’t use data from climate stations that are unable to provide it.

What this article is referring to is the "Urban City Island Effect", a phenomenon known to scientists and meteorologists for decades. Virtually every urban area is going to be hotter than surrounding communities even a mere 20 miles out, because of the ability of the mass of roads and concrete structures being able to absorb radiant heat from the Sun all day, and the fact that the cities use high amounts of energy for powering equipment, air conditioning, cars, all generating heat. All this means is that cities will get warmer, and dissipate their heat more slowly than surrounding areas at night. That keeps the temperatures artificially higher in these areas. To continue to take temperature readings in these areas and consider them reliable is one of the ways the government can manipulate the data to make so called "average" temperatures seem higher than they really are.
We don't need to be measuring temperatures by such archaic methods now that we have satellites whose sensors can scan the surface of the entire planet, and get a much more accurate overall picture of planetary temperatures. Such methods have revealed only a slight bit of warming since the mid 1700's, which is nothing to be alarmed about since that is the time we were coming out of the "Little Ice Age" and Maunder Minimum periods. These old style temperature readings are so disingenuous because they are using a colder than average period as their starting point. As the Earth moves back to more normal temperatures from there, it gives the appearance to those who want the clock to start in the mid 18th century, that temperatures are going up at an alarming rate.
Bottom line: It's all a load of shit designed to make it easy for politicians to tax the hell out of energy usage so the money collected can be redistributed through sham programs like the U.N.'s "Green Energy Fund". |
