Here is a site that shows average annual temps various places in the
world.
http://data.giss.nasa.gov/gistemp/station_data/
Pick out an area and see what the average annual temps have been.
Note
that the
temps of high population areas rises at a higher rate than does that
for
urban
areas. In most places that I looked, if the area was urban, and the
data
went
back a 100 years or so, there was very little change.

There are hypothesis that the Urban areas are measured incorrectly.
Most
readings are from ground based thermometers, and over the years the
areas
around the thermometers have been built up a lot. And the extra
buildings
add an error to the reading. Spaced based readings have not changed
much
over the years. Lots less than the ground based readings.
Yes, the temp rise in urban areas would seem to be related to the
quantity
of
concrete in urban areas. This would indicate that a return to wooden
buildings
with straw roofs would be in order. Asphalt and concrete roads also
retain
heat
much better than dirt roads, so we should go back to dirt roads.
You're such a visionary. How about requiring that companies use existing
empty commercial real estate, rather than mowing down green space until
there's nothing left but a few weeds poking out of the cracks?
Sounds like a good idea. I've also seen the use of gravel in parking lots,
instead of concrete. Gravel allows water to penetrate and not become more
polluting run-off.
Doug hits a hot button with that comment. So much of the urban sprawl is
the direct result of guvmint and environmentalists. From the regulations
and lawsuit exposure of "brownfield" development, to the "open space"
requirements of tree hugging suburbanites, to the illl thought interstate
highways cutting through the middle of cities, to the endless expansion of
water and sewer systems because they are one of the few money making
ventures of city guvmints............it has all helped create this vast
waste of resources by means of low density sprawl across the country.
