This would tend to result in increased heat flux to the ice, a positive climate feedback that would melt more ice. (psc.apl.washington.edu)
My question is, how do expect to be able to maintain a much higher temperature gradient during the LGM than we have today between tropics and high latitudes, since this would tend to increase heat flux. (realclimate.org)
Upper 700m temps flat, so if they are under the glare of an increased heat flux then more hot water has to go down to the depths and, in a zero sum game, cold water from below 700m must come up. (judithcurry.com)
