The post 1995 AMO and Arctic warming is the natural response to the decline in solar wind pressure since then, by it increasing negative NAO / AO conditions, and thereby increasing the poleward heat transports.

The conventional view on the connection between the AMOC and Arctic sea ice is that a weakening of the AMOC should reduce ocean poleward heat transport and, hence, expand sea ice.

However periodically due to increased poleward heat flux the winds slacken around the polar vortex and may even reverse direction and flow instead from east to west.

Major differences in simulated surface salinities had a significant impact on the calculated poleward heat transports.

Of course, there are plenty of negative feedbacks as well (the increase in long wave radiation as temperatures rise or the reduction in atmospheric poleward heat flux as the equator - to - pole gradient decreases) and these (in the end) are dominant (having kept Earth's climate somewhere between boiling and freezing for about 4.5 billion years and counting).

Scientists are still trying to decide how the poleward heat transport will be affected by global warming — but the rapid changes at the poles seem to involve a lot of heat transport into that region via both the atmosphere and the oceans.

Suppose that there has been a multi-century increase in the poleward heat transport in the oceans due to internal variability, which warms the poles, reduces ice extent and albedos, and thereby warms the planet.

RE # 11 The role of hurricanes in the poleward heat transport immediately leads to the question, how is the poleward heat transport divided between atmospheric and oceanic routes?

And no, there is no huge plunge in tropical or global surface air temperatures when the ocean circulation spins up because there is a near - compensating decrease in poleward heat transport via the atmospheric circulation.

Changes here have a long term effect, affecting the strength of the north - ward horizontal flow of the Atlantic's upper warm layer, thereby altering the oceanic poleward heat transport and the distribution of sea surface temperature (SST — AMO), the presumed source of the (climate) natural variability.

So in Greenland it got warmer both because of higher CO2, more sunlight at high latitudes during summer, AND because of increased poleward heat flow.

This paper is an assessment of the current climate poleward heat transport.

Furthermore, even if the net meridional overturning circulation, which is broader than just the Gulf Stream, slows, that doesn't mean that the poleward heat transport will be reduced, as a warmer wetter atmosphere can also transport a great deal of heat (latent heat) to poleward regions, which seems to be what has been happening.

There may also be additive effects, i.e. natural variability imposed on polewards heat transfer and sea ice (the Artic Oscillation, say).
