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?
