(See color insert.) The number of days in which the temperature exceeds 100ºF by late this
century, compared to the 1960s and 1970s, is projected to increase strongly across the United
States. For example, parts of Texas that recently experienced about 10–20 days per year over
100ºF are expected to experience more than 100 days per year in which the temperature exceeds
100ºF by the end of the century under the higher-emissions scenar ...
