'Nature may play a role in Arctic thaw'
There's more to the recent and dramatic and alarming thawing of the Arctic region than can be explained by human-caused global warming alone, a new study says. Nature is pushing the Arctic to the edge too.

There's a natural cause that may account for much of the Arctic warming , which has melted sea ice , ice sheets and glaciers, according to a study published Thursday in the journal "Nature".

New research points a finger at a natural and cyclical increase in the amount of energy in the atmosphere that moves from the south to north around the Arctic Circle.

don't have much escaping

Right you are, that convection won't result in much of the final loss of energy to space. It is radiation that will ultimately release energy from the grip of gravity. Convection would allow the energy to get above the greenhouse gasses if the atmospheric layers did not form bands and barriers. That is not the case on our planet.
