The current era (at least under present definitions), known as the Holocene, began about 11,700 years ago, and was marked by warming and large sea level rise coming out of a major cool period, the Younger Dryas.

A current major research focus for SEA is studies of marine mammal communication and behavior and how each changes as a function of sound exposure.

During this period, major disturbances occurred throughout the entire California Current ecosystem including mortality events of sea lions, fur seals, common murres, and Cassin's auklets, as wellasa persistent toxic algae bloom that affected the clam harvest season and the crab, sardine, and anchovy fishing seasons.

Suffice it to say that there are indications that at least a major part of the current sea ice retreat is due to naturally occurring shifts in weather patterns, rather than simply to Arctic swarming caused by human GHG emissions, as some people apparently believe.

The AMO1 (compressed) time sequence is a bit perplexing, but it is to do with North Icelandic Jet current, major player in the Nordic Seas summer oceanic heat release into atmosphere.

Whether it is the unanimous opinion by scientists regarding the 18 - year «global warming» pause; or the last 9 years for the complete lack of major hurricanes; or the inexplicable and surprisingly thick Antarctic sea ice; or the boring global sea level rise that is a tiny fraction of coastal - swamping magnitude; or food crops exploding with record production; or multiple other climate signals - it is now blatantly obvious the current edition of the AGW hypothesis is highly suspect.

In order to properly understand, what is going on in the Arctic ocean, we first must understand the oceanic oscillation and the currents in this vast ocean, it is interesting to note, Sweden is recalling its ice breaker from the USA Antarctic survey, and there is concern in the sea of Okhotsk — where, for the last couple of years breaking the winter sea ice has been a major problem, colder here, relatively «warmer» there etc..

WASHINGTON — A sobering new report warns that the oceans face a «fundamental and irreversible ecological transformation» not seen in millions of years as greenhouse gases and climate change already have affected temperature, acidity, sea and oxygen levels, the food chain and possibly major currents that could alter global weather.

The tropospheric responses — SAM and NAM especially — are in sea level pressure which are a major determinant of winds, storms and currents.

Here, we have shown that this warming was associated and presumably initiated by a major increase in the westerly to south - westerly wind north of Norway leading to enhanced atmospheric and ocean heat transport from the comparatively warm North Atlantic Current through the passage between northern Norway and Spitsbergen into the Barents Sea.»

While the effects of higher temperatures are still poorly understood, scientists are concerned that climate change could have a major impact on weather patterns, the distribution of ice, ecosystems, and ocean currents and sea levels.

Climate change is indeed expected to influence certain major ocean currents, in part by affecting the winds and other atmospheric patterns that help to drive the movement of the seas.

This report discusses our current understanding of the mechanisms that link declines in Arctic sea ice cover, loss of high - latitude snow cover, changes in Arctic - region energy fluxes, atmospheric circulation patterns, and the occurrence of extreme weather events; possible implications of more severe loss of summer Arctic sea ice upon weather patterns at lower latitudes; major gaps in our understanding, and observational and / or modeling efforts that are needed to fill those gaps; and current opportunities and limitations for using Arctic sea ice predictions to assess the risk of temperature / precipitation anomalies and extreme weather events over northern continents.

As far as current global observations are concerned, Hansen cites both the decline of Arctic sea ice and the worldwide retreat of mountain glaciers as causes for major concern.

A major factor is that everything is expressed as being global, wheras most of the extremes are local, and compartimentalized by sea currents, mountains, whatever.
