ABSTRACT
This chapter presents some statements about climate change that are deserve to be promoted from hypotheses to stipulation. It mentions some conventional wisdom about climate change that merits demotion to hypotheses. A stipulation is that both a cooler climate and a warmer climate with the same water resources is unlikely. This allows to concentrate on three future situations for any locality: same climate, same water; warmer climate, less water; and warmer climate, more water. One piece of conventional wisdom is that "waiting will only drive up costs". A second bit of conventional wisdom is "there are only losers from climate change". A third conventional generalization is that "anticipated changes are unprecedented". A fourth bit of conventional wisdom is that "cutting forests always increases the CO2 in the air". The chapter also discusses some issues that hang over the whole matter of climate change and agriculture.
