The researchers identified several key circulation patterns that affected the winter temperatures from 1979 to 2013, particularly the Arctic Oscillation (a climate pattern that circulates around the Arctic Ocean and tends to confine colder air to the polar latitudes) and a second pattern they call Warm Arctic and Cold Eurasia (WACE), which they found correlates to sea ice loss as well as to particularly strong winters.

Mori et al. identified two circulation patterns that drove winter temperatures in Eurasia from 1979 to 2013: the Arctic Oscillation (which confines colder air to the polar latitudes) and a pattern dubbed «Warm Arctic and Cold Eurasia» (WACE), which correlated both to sea - ice loss in the Barents - Kara Sea and to particularly cold winters; its impact has more than doubled the probability of severe winters in central Eurassea - ice loss in the Barents - Kara Sea and to particularly cold winters; its impact has more than doubled the probability of severe winters in central EurasSea and to particularly cold winters; its impact has more than doubled the probability of severe winters in central Eurasia.

The technique may help scientists better track population numbers of these penguins, which are threatened by warmer sea temperatures.

But climate change has brought milder winters, warmer sea temperatures and bigger storms, which create a vicious cycle that promises less sea ice and more wind and open water to generate ice - crushing waves.

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.

Jet engine exhaust emits carbon dioxide, which drives climate change by warming the atmosphere, leading to increasing global temperatures, rising seas and extreme weather.

This refers to the limit of warming beyond which the island states will become unviable in the face of threats including rising sea levels, flooding, ocean acidification and drought.

A hotter atmosphere warms the oceans, which expand, leading to sea level rise.

At the same time, the El Niño event brought warmer sea - surface temperatures, which have been shown to correlate with outbreaks of mosquito - transmitted diseases.

One of the major thrusts of the report, which was discussed at PCAST's 15 March meeting in Washington, D.C., was to emphasize «climate preparedness» — a relabeling of the idea that the government should be doing more to prepare the nation to adapt to changes expected to be caused by global warming, such as rising seas, droughts, and floods.

«But the deeper ocean shows no slowing in warming, and sea levels continue to rise — which we believe is still mostly down to thermal expansion,» says Rintoul.

On average, Antarctic sea ice may be considerably thicker than once thought, which could significantly change how scientists assess sea ice dynamics and their interactions with the ocean in a warming world.

A warming planet, which is causing sea ice in Antarctica (and elsewhere) to melt, may ultimately be to blame for the plummeting penguin population

Nor even the catastrophic failure of Scottish seabirds to breed, which some researchers attributed to a dearth of plankton in the warming waters of the North Sea.

A warm bias in sea surface temperature in most global climate models is due to a misrepresentation of the coastal separation position of the Gulf Stream, which extends too far north of Cape Hatteras, North Carolina.

The research published in the journal Science Advances predicts that as the oceans warm fish — which appear to be superior predators in warm water — will extend their ranges away from the equator and cause a decline in the diversity of invertebrates such as crabs, lobsters, sea urchins and whelks.

At a global scale, the increased melting of the ice sheet contributes to rising sea level and may impact global ocean circulation patterns through the so - called «thermohaline circulation'that sustains among others, the Gulf Stream, which keeps Europe warm.

A possible cause for the accelerated Arctic warming is the melting of the region's sea ice, which reduces the icy, bright area that can reflect sunlight back out into space, resulting in more solar radiation being absorbed by the dark Arctic waters.

Global warming causes mountain glaciers to melt, which, apart from the shrinking of the Greenlandic and Antarctic ice sheets, is regarded as one of the main causes of the present global sea - level rise.

It's unclear whether this year's strong El Niño event, which is a naturally occurring phenomenon that typically occurs every two to seven years where the surface water of the eastern equatorial Pacific Ocean warms, has had any impact on the Arctic sea ice minimum extent.

The two main forces that conspire to destroy Earth's massive polar ice sheets are heat, which melts their surfaces via sunlight and warm air, and gravity, which drives glaciers to slide to the sea.

«The sea ice cap, which used to be a solid sheet of ice, now is fragmented into smaller floes that are more exposed to warm ocean waters.

At the same time as the surface is cooling, the deeper ocean is warming, which has already accelerated the decline of glaciers in the Amundsen Sea Embayment.»

As the atmosphere warms, heat is transferred to the oceans, which causes water expansion and rising sea levels.

That may not have occurred during the warm period 400,000 years ago, known as Marine Isotope Stage 11 to scientists, which featured elements such as boreal forest on Greenland and higher sea levels.

Kevin Trenbeth, a climate scientist at the National Center for Atmospheric Research in Boulder, Colo., said the study didn't account for changes in sea surface temperatures, which are the main drivers of changes in the position of the rain belts (as is seen during an El Nino event, when Pacific warming pushes the subtropical jet over the Western U.S. southward).

Global warming has caused big problems for polar bears, which depend on sea ice for access to the ocean so they can hunt seals and other prey.

When the AMO is in its positive phase and the sea surface temperatures are warmer, the study has shown that the main effect in winter is to promote the negative phase of the NAO which leads to «blocking» episodes over the North Atlantic sector, allowing cold weather systems to exist over the eastern US and Europe.

Sea surface temperatures in the Pacific Ocean are warmer than normal — El Niño conditions — which suppress rainfall in the eastern Amazon.

Since the 1970s the northern polar region has warmed faster than global averages by a factor or two or more, in a process of «Arctic amplification» which is linked to a drastic reduction in sea ice.
