Just for one example, if it turns out that, between melt of sea ice and Greenland ice, the North Atlantic Current slows or stops, we would expect to see fairly dramatically colder weather in Europe for a while, even thought this condition could be directly linked to results produced by GW (though in the long term, the warming would, presumably eventually overtake the cooling from change in ocean currents).

Research conducted at The University of Texas at Austin has found that changes in ocean currents in the Atlantic Ocean influence rainfall in the Western Hemisphere, and that these two systems have been linked for thousands of years.
I do see the possibility (again, as a non-scientist) of considerably more chaos arising at a regional level, particularly due to possibly chaotic changes in ocean currents.
It may lead to changes in ocean currents, such as the Gulf Stream, the destructive consequences of which would incalculable.
Changes in ocean currents are also lead to upwelling of warm water, which also increases evaporation — and thus snow.
The Arctic took another 3,000 - 4,000 years to warm this much, primarily because of the fact that the Northern Hemisphere had huge ice sheets to buffer warming, and the fact that changes in ocean currents and Earth's orbital configuration accelerated warming in the south.
The sun and moon tug on the planet, while the drift of continents, changes in ocean currents, and the rebounding of the crust since the retreat of ice age glaciers all shift mass around, altering Earth's moment of inertia and therefore its spin.
Changes in ocean currents, Kennett says, triggered the methane bursts by channeling warmer water over continental slopes, as at Storegga.
There is some evidence tentatively suggesting that the early 20th century warming was particularly in the Arctic, possibly suggesting a change in ocean currents in the North Atlantic.

Oleg Sorokhtin of the Russian Academy of Sciences Institute of Ocean Studies, and many other Russian scientists maintain that global climate depends predominantly on natural factors, such as solar activity, precession (wobbling) of the Earth's axis, changes in ocean currents, fluctuations in saltiness of ocean surface water, and some other factors, whereas industrial emissions do not play any significant role.
Now for sea ice, this type of ice is influenced by year - to - year changes in wind directions and changes in ocean currents.
cooling in the North Atlantic basin due to changes in ocean currents.
But there's also some change in the ocean currents that's periodic so there is expected to be some cooling within the next decade or so.
Differences in the regional heating of the oceans, changes in ocean currents, and a variety of other factors can contribute to regional variations in sea level rise.
