They range from changes in ocean circulation patterns caused by glacial meltwater entering the ocean to the cosmic - impact theory.

New evidence is also suggesting that changes in ocean circulation patterns played a very important role in bringing warmer seawater into the North Atlantic.

The seasonal climate may relate to changes in the ocean circulation pattern prior to 4.6 Ma that resulted in an increased temperature and atmospheric pressure gradient between the east coast of North America and the Atlantic Ocean, but this climate phase seems to be only a temporary condition, as underlying and overlying sediment are both consistent with drier conditions.

One of the most significant potential mechanisms is a shift in an ocean circulation pattern known as thermohaline circulation, which would have widespread consequences for Europe and the U.S. East Coast.

Ongoing changes in ocean circulation patterns, which are helping to drive warm water from other parts of the sea closer to the Antarctic continent, are also believed to be a major factor.

They showed that temperatures warmed in both the North Pacific and Greenland, likely due to changes in ocean circulation patterns.

For instance, the Medieval Climatic Anomaly was characterised by relatively high solar activity, low volcanic activity and possible changes in ocean circulation patterns.

In this case, it is possible that the instability is in the ocean circulation patterns — and that the mass balances potentially caused by angular momentum shifts lead the propagation of the resultant temperature shifts.

Ongoing changes in ocean circulation patterns, which are helping to drive warm water from other parts of the sea closer to the Antarctic continent, are also believed to be a major factor.

This can lead to major climatic changes such as a change in rainfall patterns, changes in ocean circulation patterns, warming in some areas, dramatic cooling in others, rising sea levels and coastal flooding, due to melting ice sheets and thermal expansion of seawater.
