More Clouds tend to heat the Polar Regions, while less clouds
heat the tropics.

This should appear self evident? i.e -
A/. Fewer tropic clouds radiate more heat back into space.
B/. More clouds trap heat in the air.
Its this warmer air reaching the Polar regions, that is tending
to melt it.

Anyone disagree with this?
Since:
The slant angle of the Sun on all Polar regions, can hardly do as much melt damage, as incoming warmish cloud trapped Polar air.

I have had this thought after taking a quick look at 'Hadley Cells' plus the CERES data, averaged from 7 different Spacecraft.
However I must state, my *comment is not a direct result of any info contained below.

Various comments of mine in-"Its raining at The North Pole" in this Forum earlier. With attention to Artic windspeed, and that rain has to condense around something, before it falls, have helped in coming to my conclusion.
Plus the fact that there are so many unknowns within the 'Climate Equation' that we should use only the latest ten year old Datas, and wait and see.

Even Dr Bruce Wielicki suggests that "Since clouds were thought to be the weakest link in predicting future climate change from greenhouse gases, these new results are unsettling"
