Sentences with phrase «major warm ocean current»

Not exact matches

Real scientists (as opposed to climate modellers) have long maintained that the decline in Arctic ice is caused not by warmer air — in the past year or two Arctic air temperatures have actually been falling — but by shifts in major ocean currents, pushing warmer water up into the Arctic Circle.

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..

Previous large natural oscillations are important to examine: however, 1) our data isn't as good with regards to external forcings or to historical temperatures, making attribution more difficult, 2) to the extent that we have solar and volcanic data, and paleoclimate temperature records, they are indeed fairly consistent with each other within their respective uncertainties, and 3) most mechanisms of internal variability would have different fingerprints: eg, shifting of warmth from the oceans to the atmosphere (but we see warming in both), or simultaneous warming of the troposphere and stratosphere, or shifts in global temperature associated with major ocean current shifts which for the most part haven't been seen.

One of the consequences could be a disruption of major ocean currents, particularly those flowing north and south, circulating warm water from the equator to polar regions and cold water from the poles back to the equator.

Deep ocean currents occasionally push through the warm surface layer in the south eastern Pacific in one of the major areas for upwelling on the planet.

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.»

Atlantic Meridional Overturning Circulation A major current in the Atlantic Ocean, characterized by a northward flow of warm, salty water in the upper layers of the Atlantic, and a southward flow of colder water in the deep Atlantic.
