Table 5. Projected rates of extreme temperature frequencies (daily Tmax ≥ 35°C) (day decade-1) during the 21st century in two important growth stages of corn cultivars planted according to the business-as-usual date, scenario-1 (14 days before the last spring freeze), and scenario-2 (1 day after the last spring freeze) at three locations in the Northeast United States, under two emission scenarios.
Rates are reported as median values across projected data from 9 Global Climate Models.
