Shock News : “Heat Island Effect” Warms Temperature Data

The data doesn’t matter. We’re not basing our recommendations
on the data. We’re basing them on the climate models

It doesn’t matter what is true,
it only matters what people believe is true

“As we all know, this isn’t about truth at all, its about plausibly deniable accusations.”

What Is an Urban Heat Island?

As urban areas develop, changes occur in their landscape. Buildings, roads, and other infrastructure replace open land and vegetation. Surfaces that were once permeable and moist become impermeable and dry.1 These changes cause urban regions to become warmer than their rural surroundings, forming an “island” of higher temperatures in the landscape.

Heat islands occur on the surface and in the atmosphere. On a hot, sunny summer day, the sun can heat dry, exposed urban surfaces, such as roofs and pavement, to temperatures 50–90°F (27–50°C) hotter than the air,2 while shaded or moist surfaces—often in more rural surroundings—remain close to air temperatures. Surface urban heat islands are typically present day and night, but tend to be strongest during the day when the sun is shining.

1967 : Scientific American Reported 4 Degrees UHI In DC

Posted on Real Science January 13, 2014

UHI causes temperatures to rise as suburban sprawl spreads. NOAA and NASA have responded by making massive adjustments in the wrong direction.

Hansen Celebrating A Quarter Century Clueless About UHI

Posted on Real Science December 18, 2013 by 

Hansen still can’t find the UHI, 25 years later.

U.S. Data Since 1895 Fail To Show Warming Trend

Published: January 26, 1989

What About Urbanization? One aspect of the study that Dr. Hanson said was interesting was the finding that the urbanization of the United States has apparently not had a statistically significant effect on average temperature readings. A number of scientists have theorized that the replacement of forests and pastures by asphalt streets and concrete buildings, which retain heat, is an important cause of rising temperatures.

This would be same UHI effect which scientists measured in 1907.

Fort Collins – A Classic Study in UHI

Posted on September 16, 2013by 

The weather station at Fort Collins is located on the CSU campus, and hasn’t moved for over a hundred years. Unlike most of the US, it shows a strong increase in the number of record maximums, and a strong decrease in record minimums.

aaa

The weather station started out in the middle of a farm, and is now in the middle of a very busy parking lot and bus terminal.

In 1937, the station was located in the middle of a farm,

aaaaa

By 1950, the area was starting to get built up.

aaaaaaa

By 1969, the city had surrounded the weather station.

aaaassss

Now it is in the middle of a parking lot.

aassaa

It must be the CO2.

Confusing UHI With Global Warming

screenhunter_10-jun-09-19-57

Two hundred years before Hansen, Thomas Jefferson was an ardent believer in global warming – until Noah Webster explained to him that he was confusing UHI effects with climate.

In his 1787 book, Notes on the State of Virginia, Jefferson launched into a discussion of the climate of both his home state and America as a whole. Near the end of a brief chapter addressing wind currents, rain and temperature, he presented a series of tentative conclusions: “A change in our climate…is taking place very sensibly. Both heats and colds are become much more moderate within the memory of the middle-aged. Snows are less frequent and less deep….The elderly inform me the earth used to be covered with snow about three months in every year. The rivers, which then seldom failed to freeze over in the course of the winter, scarcely ever do so now.” Concerned about the destructive effects of this warming trend, Jefferson noted how “an unfortunate fluctuation between heat and cold” in the spring has been “very fatal to fruits.”

Webster concluded by rejecting the crude warming theory of Jefferson and Williams in favor of a more subtle rendering of the data. The conversion of forests to fields, he acknowledged, has led to some microclimatic changes—namely, more windiness and more variation in winter conditions. But while snow doesn’t stay on the ground as long, that doesn’t necessarily mean the country as a whole gets less snowfall each winter: “We have, in the cultivated districts, deep snow today, and none tomorrow; but the same quantity of snow falling in the woods, lies there till spring….This will explain all the appearances of the seasons without resorting to the unphilosophical hypothesis of a general increase in heat.

Webster’s words essentially ended the controversy. While Jefferson continued to compile and crunch temperature data after his retirement from the presidency, he never again made the case for global warming.

Jefferson had no idea that people reproducing his error would two hundred years later become the basis for destroying the democracy he created. Unlike Jefferson, Hansen is incapable of learning from his mistakes.

The following links detail how temperature data has been ‘adjusted’. What stands out is that the adjustments invariably seem to be massaged adjusted the illogical way. That is, the past, with less urbanisation, is “cooled” and the present, with greater urbanisation, is “heated”.

One could only assume that the impetus for reversing logic, would be to fit the narrative that human’s are frying the atmosphere with their evil gases. Nahh, that’s just a climate denier, conspiracy theory…
