important for U.S. domestic oil and gas production (Figures 5 and 6 ) suggests some pos-
sible issues associated with temperature changes in a high emissions scenario. Figure 7
indicates more signiicant vulnerability issues for ethanol production, where about 80%
of current production comes from seven states that are subject to both precipitation and
temperature changes. Issues may also exist for oil and gas production in the U.S from
shale: e.g., water needs for shale gas fracturing.
