There are 200 million cubic Miles of ocean below 1000 meters, where sunlight never reaches, and there 1.1 x 10¹² gallons per cubic mile. There is NO lack of frigid COLD, to offset our measured average of 1 (or even 2°F) temperature increase here on the surface.l: Tap into enough of that vast COLD to offset our small warming here at the surface and in a few *centuries* you’d increase the temperature of *maybe* 1% of it by 1-2°F [ from 39° to 40°-41°].
