These maps show the projected increase in average daily July heat index relative to the present. The largest increases are in the southeastern states, where the models projects increases of more than 25°F.

A July day in Atlanta that now reaches 105°F would reach 115°F in the Hadley model, and 130°F in the Canadian model.

The oceans have absorbed about 30 times more heat than the atmosphere since 1955

Expected sea level increase 21st Century:+ 1.2 meter
