While it is still possible that other factors, such as heat storage in other oceans or an increase in aerosols, have led to cooling at the Earth's surface, this research is yet another piece of evidence that strongly points to the Pacific Ocean as the reason behind a slowdown in warming.

The warming also indicates that a large amount of heat is being taken up by the ocean, demonstrating that the planet's energy budget has been pushed out of balance.

Gerald Meehl, a climate scientist at the National Center for Atmospheric Research who was also an author on the paper, said this research expanded on past work, including his own research, that pointed to the Interdecadal Pacific Oscillation as a factor in a warming slowdown by finding a mechanism behind how the Pacific Ocean was able to store enough heat to produce a pause in surface warming.

Scientists can measure how much energy greenhouse gases now add (roughly three watts per square meter), but what eludes precise definition is how much other factors — the response of clouds to warming, the cooling role of aerosols, the heat and gas absorbed by oceans, human transformation of the landscape, even the natural variability of solar strength — diminish or strengthen that effect.

In this case, though, the heat produced not volcanoes but a warm ocean sloshing beneath Europa's icy crust.

Global climate models need to account for what Meehl calls «slowly varying systems» — how warmer air gradually heats the ocean, for example, and what effect this warming ocean then has on the air.

Last year, a study published in Science Advances found that the oceans have been steadily storing more heat since the 1980s and that deeper layers of the ocean are starting to warm up, as well.

«If the winds continue to increase as a result of global warming, then we will continue to see increased energy in eddies and jets that will have significant implications for the ability of the Southern Ocean to store carbon dioxide and heat,» said Dr Hogg.

«Even if we stopped all greenhouse gas emissions today, we'd still have an ocean that is warmer than the ocean of 1950, and that heat commits us to a warmer climate,» Gille said.

Solar heat or warm ocean waters fit the bill.

According to the new findings, Earth may be able to significantly reduce global warming by releasing some of the heat through a «vent» in the cloud cover over the Pacific Ocean.

Charlie's research told him that during El Niño weather cycles, the surface seawaters in the Great Barrier Reef lagoon, already heated to unusually high levels by greenhouse gas — induced warming, were being pulsed from a mass of ocean water known as the Western Pacific Warm Pool onto the reef's delicate living corals.

So, for example, a big part of what drives a hurricane is the fact that you've got a lot of warm water near the surface of the ocean that is transferring heat into the air, and that's what's moving up, and that is a big part of then what's propelling the entire bigger storm system.

It takes a long time for the ocean to respond to increasing heat, so even if greenhouse gas emissions dropped to zero tomorrow, the world's seas would continue to rise for centuries because of the warming that's already happened.

We've narrowed the uncertainty in surface warming projections by generating thousands of climate simulations that each closely match observational records for nine key climate metrics, including warming and ocean heat content.»

Conversely, when there is less Arctic sea ice, the ocean absorbs more heat from the sun, adding to global warming.

As the world's climate warms, will the Pacific Ocean make matters worse by dumping extra heat into the atmosphere?

Extreme weather does not prove the existence of global warming, but climate change is likely to exaggerate it — by messing with ocean currents, providing extra heat to forming tornadoes, bolstering heat waves, lengthening droughts and causing more precipitation and flooding.

If it is permanent, «it is logical to suggest that the winds and ocean currents change accordingly and switch us into a new regime where heat is not buried so deeply, and we jump to the next level in global warming,» Trenberth said.

Another principal investigator for the project, Laura Pan, senior scientist at the National Center for Atmospheric Research in Boulder, Colo., believes storm clusters over this area of the Pacific are likely to influence climate in new ways, especially as the warm ocean temperatures (which feed the storms and chimney) continue to heat up and atmospheric patterns continue to evolve.

The team chose the specific area examined in the study because it is Earth's warmest open ocean region and a primary source of heat and water vapor to the atmosphere.

The warm waters give up their heat in the bitterly cold regions monitored by OSNAP, become denser, and sink, forming ocean - bottom currents that return southward, hugging the perimeter of the ocean basins.

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

As the storm moves forward over these eddies, the warm ocean waters below help fuel the storm's intensity through enhanced and sustained heat and moisture fluxes.

Their studies strengthen the theory that a warmer climate heats the ocean surface and fuels massive storms.

He proposed that the bottom layers of Europa's ice shell would be slightly warmer than the ice on top, due to heating from both the ocean below and the crushing pressure of the miles - thick ice above.

Some scientists have tied the phenomenon, called the global warming «pause,» to the deep oceans» taking up more heat.

The oceans are major players in the climate system, absorbing about 90 percent of the heat of global warming.

Faster flow is more turbulent, and in this turbulence more heat is mixed into AABW from shallower, warmer ocean layers — thus warming the abyssal waters on their way to the Equator, affecting global climate change.

If the heat is weaker (right), Europa might have a thick layer of warm ice atop its ocean.

The continued top ranking for 2016 may be due in part to El Niño, a cyclical climate event characterized by warmer - than - average waters in the equatorial Pacific Ocean, which generated some of the global heat that year.

Climate models do not predict an even warming of the whole planet: changes in wind patterns and ocean currents can change the way heat is distributed, leading to some parts warming much faster than average, while a few may cool, at least at first.

«There is evidence for global warming on a number of levels, and the planet has been warming, the oceans have been taking up heat, sea levels have been rising, land snow has been melting, glaciers are melting, and all these other things, so the reality of global warming is uncontroversial.»

A low - altitude flow of warm, moist air from an ocean area combined with a flow of cold, dry polar air high up creates maximum instability, which means that parcels of air heated near the surface rise rapidly, creating powerful updrafts.

As a result of atmospheric patterns that both warmed the air and reduced cloud cover as well as increased residual heat in newly exposed ocean waters, such melting helped open the fabled Northwest Passage for the first time [see photo] this summer and presaged tough times for polar bears and other Arctic animals that rely on sea ice to survive, according to the U.S. Geological Survey.

Ocean circulation drives the movement of warm and cold waters around the world, so it is essential to storing and regulating heat and plays a key role in Earth's temperature and climate.

That could allow heat from the ocean to be released into the atmosphere — causing a jump in atmospheric global warming, Trenberth says: «This could be a very important year.»

And the warming of the upper 2 kilometers of the world ocean — a huge heat sink relative to the atmosphere — continued apace through the 2000s.

So the report notes that the current «pause» in new global average temperature records since 1998 — a year that saw the second strongest El Nino on record and shattered warming records — does not reflect the long - term trend and may be explained by the oceans absorbing the majority of the extra heat trapped by greenhouse gases as well as the cooling contributions of volcanic eruptions.

«Extra heat means extra sea level rise, since warmer water is less dense, so a warmer ocean expands.»

What scientists discovered in 2014 is that since the turn of the century, oceans have been absorbing more of global warming's heat and energy than would normally be expected, helping to slow rates of warming on land.
