Sea ice reflects most of the sun's energy, he explained, whereas the open ocean absorbs more energy, and thus the disappearance of sea ice triggers even more warming, in a positive - feedback loop called albedo.

«As the climate gets warmer, the thawing permafrost not only enables the release of more greenhouse gases to the atmosphere, but our study shows that it also allows much more mineral - laden and nutrient - rich water to be transported to rivers, groundwater and eventually the Arctic Ocean,» explained Ryan Toohey, a researcher at the Interior Department's Alaska Climate Science Center in Anchorage and the lead author of the study.

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.

It should also be noted that the authors examined whether the large - scale ocean circulation, the Meridional Overturning Circulation (MOC), and two other ocean phenomena - the Pacific Decadal Oscillation (PDO) and Atlantic Meridional Oscillation (AMO)- could explain the warming in the 20th century simulations, but found no evidence in the models.

For naysayers who may claim that natural ocean processes only explain variability, and not overall trends (warming), we have this:

In the part of the «Swindle» film where I am describing the fact that the ocean tends to expel carbon dioxide where it is warm, and to absorb it where it is cold, my intent was to explain that warming the ocean could be dangerous — because it is such a gigantic reservoir of carbon.

So if you can explain to me how the atmosphere could cause these three oceans to warm and allow the rest to languish or cool, I would be very interested to hear it.

Cooling sea - surface temperatures over the tropical Pacific Ocean — part of a natural warm and cold cycle — may explain why global average temperatures have stabilized in recent years, even as greenhouse gas emissions have been warming the planet.

Guemas et al. (Nature Climate Change 2013) shows that the slower warming of the last ten years can not be explained by a change in the radiative balance of our Earth, but rather by a change in the heat storage of the oceans, and that this can be at least partially reproduced by climate models, if one accounts for the natural fluctuations associated with El Niño in the initialization of the models.

Gavin disputes that the main driver of the sea ice retreat is the albedo flip, but we are seeing not only polar amplification of global warming but positive feedback, which would not be explained simply by radiative forces and ocean currents.

I particularly enjoyed the slides that, when combined (1) provided an overview of hotter and cooler CO2 molecules as it relates to how they are seen from outer space and from profile — because this will make it easier for me to explain this process to others; (2) walked through the volcanic and solar activity vs assigning importance to CO2 changes — because this another way to help make it clearer, too, but in another way; (3) discussed CO2 induced warming and ocean rise vs different choices we might make — because this helps point out why every day's delay matters; and (4) showed Figure 1 from William Nordhaus» «Strategies for Control of Carbon Dioxide» and then super-imposed upon that the global mean temperature in colors showing pre-paper and post-paper periods — because this helps to show just how far back it was possible to make reasoned projections without the aid of a more nuanced and modern understanding.

The recent slower warming is mainly explained by the fact that in recent years the La Niña state in the tropical Pacific prevailed, in which the eastern Pacific is cold and the ocean stores more heat (2).

I think the latter is likely — these recent cold winters are part of the much - discussed «warm Arctic — cold continents» pattern (see, eg, Overland et al 2011) and could be related to the dwindling ice cover on the Arctic Ocean, as we explained here.

Instead, they discuss new ways of playing around with the aerosol judge factor needed to explain why 20th - century warming is about half of the warming expected for increased in GHGs; and then expand their list of fudge factors to include smaller volcanos, stratospheric water vapor (published with no estimate of uncertainty for the predicted change in Ts), transfer of heat to the deeper ocean (where changes in heat content are hard to accurately measure), etc..

Henry@Willis I think to explain the phenomena of why the oceans do not get warmer than 30 - 33C When the top layer of molecules of the water in the reservoir reaches a certain temp., namely the boiling point at ruling pressure, it simply evaporates and thereby it cools the remaining liquid in the reservoir.

However, Watanabe et al. (2013) suggests that these factors can't explain most of the slowed surface warming, which his study attributes to a more efficient transfer of heat to the deep oceans.

By comparing modelled and observed changes in such indices, which include the global mean surface temperature, the land - ocean temperature contrast, the temperature contrast between the NH and SH, the mean magnitude of the annual cycle in temperature over land and the mean meridional temperature gradient in the NH mid-latitudes, Braganza et al. (2004) estimate that anthropogenic forcing accounts for almost all of the warming observed between 1946 and 1995 whereas warming between 1896 and 1945 is explained by a combination of anthropogenic and natural forcing and internal variability.
