impacts.
Based on the estimated coefficients
of mean temperatures in four regimes, we separate 78 cities into five areas with latitudes below 30 °, 31 ° -40 °, 41 ° -50 °, and 61 ° -70 °, and

Choice 1: How much money do we want to spend today on reducing carbon dioxide emission without having a reasonable idea
of: a) how much
climate will
change under business as usual, b) what the
impacts of those
changes will be, c) the cost
of those
impacts, d) how much it will cost to significantly
change the
future, e) whether that cost will exceed the benefits
of reducing
climate change, f) whether we can trust the scientists charged with developing answers to these questions, who have abandoned the ethic
of telling the truth, the whole truth and nothing but, with all the doubts, caveats, ifs, ands and buts; and who instead seek lots
of publicity by telling scary stories, making simplified dramatic statements and making little mention
of their doubts, g) whether other countries will negate our efforts, h) the meaning
of the word hubris, when we think we are wise enough to
predict what society will need a half - century or more in the
future?
