reduce, such as heavy industry.
Thus, if the absorption of the infrared
emission from
atmospheric greenhouse gases
reduces the gradient through the skin layer, the flow of heat from the ocean beneath will be
reduced, leaving more of the heat introduced into the bulk of the upper oceanic layer by the absorption of sunlight to remain there to increase water temperature.
With a lifetime of ~ 10 years, spreading
emissions over 30 - year period would of course
reduce the peak

While CO2

If the anthropogenic forcing wouldn't keep increasing anymore (because we would manage to suddenly
