was the Earth's temperature yesterday? Nobody knows. In fact, it's a
ridiculous question. Almost every place on Earth today has a different
temperature from that of any other location. So, is our planet's
temperature rising? Do we even know?
However, it is officially admitted: Global warming
stopped 15-20 years ago. The mainstream media is struggling very hard
to explain this away. They admit that the Earth stopped warming 15 to
20 years ago.
But just you wait -- disaster is coming unless we vote
liberals into office. They cannot explain the pause. Yet they "know" global warming will kill us all unless we vote Democrat.
So was global warming ever real? Or is this hysteria a hoax, like the Y2K computer disaster that never happened?
concerning today's temperature first, we would have to measure hundreds
of thousands of locations and then average temperatures from all over
the planet. We don't have that many weather stations. So we don't even
know what yesterday's temperature for the planet was. We certainly
don't know what the temperature was a hundred years ago or a thousand
today's weather measurements accurate? Heck no. Weather stations are
measuring the jet blast from airplanes taking off at airports, the heat
from air conditioners on office building rooftops, the heat of asphalt parking lots and streets and cities.
Anthony Watts is one of the greatest heroes of truth and freedom. His
blog "Watts Up With That?" has changed the world and is one of the most
influential resources on global warming. Watts became truly famous with
his recurring "How Not to Measure Temperature" series reviewing the
world's automated weather stations.
For example, concerning Henderson Field, in the Solomon Islands, Watts reported
that jet exhaust from taxiing airplanes blows straight into the weather
equipment. Do we care about the Solomon Islands? Well, if you are
trying to track the planet's overall temperature, yes, you must include
the whole world. Otherwise, you are simply watching weather variations
moving around from one part of the planet to another.
weather stations were busted. Many weather stations are on the roofs
of major office buildings, where they are affected by the heat blast
from massive industrial air conditioners. The sun also heats the top of
the building and the surrounding buildings and streets. So the weather
station is actually measuring the "heat effect" of the city -- not the
climate. They are also measuring the nearby air conditioner. "How Not to Measure Temperature, Part 48" exposed a building-top station in Baltimore.
In "How Not to Measure Temperature, Part 93,"
Watts reports how the weather station most responsible for claims of
warming temperature in England is stationed next to a massive air conditioner
on the ground and a brick building. And they are all together inside a
ground depression. This traps artificial heat, causing an inaccurate
temperature reading. The temperature reading is also near industrial
activity in London.
In "Part 90," Watts reports on a station set in a small parking lot, on the asphalt, next to an air conditioner.
The blog "Gust of Hot Air"
reports on a weather station at the Marysville, California Fire
Department. It used to be in a grassy yard. Now the yard is a parking
lot. And the measurement equipment is within 10 feet of an air
conditioning unit that cools cell tower electronics and the bar-be-cue
that firefighters cook with a couple times a week.
all of the weather stations in the world were created only after the
invention of the airplane (at least those which report organized,
historical records). Very few spots on the Earth were being sampled
before World War I. But the farther back in time we go, the worse it
gets. So the sampling of the Earth's temperature was changing over
time. We are comparing apples and oranges when we compare the sample
set that exists today with the much smaller sample sets the farther we
go back through the decades of data.
isn't sampling an accepted scientific tool? Only if it is truly random
according to careful rules and techniques. Weather station samples are
fixed in certain locations, always the same, not randomly selected for
each year. And the Earth's weather is tremendously variable. But it is
not random in the sense necessary for statistical measurement. We may
not understand all the highly complex weather patterns. But the sample
of weather stations is fixed -- or in other words, not random.
are measuring not changes in the climate, but rather the "heat effect"
of expanding cities due to urban sprawl. Most temperature measurements
are at airports. A great many airports were built out in the empty
countryside, perhaps 5 to 25 miles from the city they serve. But urban
sprawl has now extended outward to those airports. So as we compare
data over past decades, we are seeing the increase in temperature caused
by expanding cities -- not a change in the planetary climate.
is well-known that there is a "heat effect" when asphalt roads and
concrete buildings replace trees, grass, and open fields. This creates a
localized increase in temperature at ground level. (However, this
affects the distribution of heat, since sunshine is still the same over
the entire planet. It probably does not change the global temperature
overall. It will increase convection and temperatures near the
ground.) Yet it's actually worse than that. And the heat content held
within water, air, and rock is different from one to the next. So
temperature swings in the air may be misleading.
the concept of a thermometer is thousands of years old, no scale of
precise standardized measurement was invented until the 1700s.
Therefore, we have no meaningful records of temperature earlier than the
Industrial Revolution, in terms of the ability to compare measurements
recorded over time. Even then, scientific instruments must be
calibrated for accuracy. Even a thermometer attempting to measure
temperature on a standardized scale may not read the same as another
thermometer. Accuracy in scientific instruments requires
standardization and careful calibration. Quality has not been
consistent since the 1700s.
So global warming
hysteria is based not on any accurate measurements of global climate,
but rather on "proxies." That is, scientists give their interpretation
of tree rings and bacterial samples in fossils. Global warming "science" is strikingly similar to a witch doctor reading the entrails of a goat.
the problem, and it is a foundational precept in science: you cannot
analyze data to a greater precision than the original measurement. So
if you have data measured only in yards, you cannot analyze that data to
draw conclusions at the level of inches. You will get errors. With global warming,
we don't know historical temperatures with precision. Therefore,
imprecise historical data cannot support the attempted predictions.
Well, then, how can we say that global warming
stopped 15-20 years ago if we really don't know what the temperature is
or has been? We have no valid basis for saying that the world is
warming. We can't say that it is or it isn't. But the whole global warming concept is simply...well...hot air.
