Using a global climate
model, a team led by Princeton University researchers measured how severely
heat waves interact with
urban heat islands, now and in the future, in 50 American cities across three climate zones.
If you take into account that virtually all the world's concrete and asphalt which causes the positive feedback of UHI (
urban heat island) was made after 1940 you could tweak up the
model inputs for solar and down for CO2 and get just the same result for surface temperature.
The base
model of the highly - styled little
urban runabout, priced at $ 18,999, comes with a 7 - inch multimedia LCD touch screen, back - up camera, six - speaker audio system with a wide variety of inputs and Gracenote technology, wireless connectivity with voice - recognition, alloy wheels, air conditioning, proximity key with push - button start, power windows and locks, remote keyless entry, power
heated mirrors, tilt & telescope steering wheel and
heated seats.
Future topics that will be discussed include: climate sensitivity, sea level rise,
urban heat island - effects, the value of comprehensive climate
models, ocean
heat storage, and the warming trend over the past few decades.
It's not about someone saying there is
urban heat bias, it's about the method of
modeling used to
model the observations which reduces the error extent.

He rewrote Wikipedia's articles on global warming, on the greenhouse effect, on the instrumental temperature record, on the
urban heat island, on climate
models, on global cooling.
@Mike Edwards: There are lots of studies — hundreds, at least — of the
urban heat island effect, and quite a lot of effort has gone into identifying, quantifying,
modelling, and adjusting for the effect of UHI on global temperature records.
In order to see the effects of extreme
heat events on the United States, the researchers developed
models to simulate scenarios analogous to that of Europe's for
heat - sensitive
urban areas.
Using a regional climate
model combined with an
urban model that allowed researchers to adjust roof reflectance, they found that the average
urban midday temperature was lowered by 1.2 degrees Celsius (2.2 degrees Fahrenheit) during
heat waves, or 50 percent more than the 0.8 degrees Celsius reduction for typical summer conditions.
The raw data is largely reliable based on the error reduction capacity built into the
modeling to reduce anomalous readings of
urban heat island effect and other station and / or measurement anomalies.
Heat Island Effect Neglible In Overall Warming, And Skewing Climate Models The study also examined the urban heat island effect — something which climate skeptics cite as invalidating evidence of warming — and found that it had a «nearly negligible» effect on the overall warming tr
