Sentences with phrase «global oceanic heat»

The influence of anthropogenic forcing has also been detected in various physical systems over the last 50 years, including increases in global oceanic heat content, increases in sea level, shrinking of alpine glaciers, reductions in Arctic sea ice extent, and reductions in spring snow cover (Hegerl et al., 2007).

Their research, published in Nature Climate Change on June 29, is the first attempt to examine and document these changes in the air - sea heat exchange in the region — brought about by global warming — and to consider its possible impact on oceanic circulation, including the climatologically important Atlantic Meridional Overturning Circulation.

Just a general observation in regards to the oceanic heat content value in determining global warming.

Polar amplification, in which temperatures at the poles rise more rapidly than temperatures at the equator (due to factors like the global atmospheric and oceanic circulation of heat from the equator to the poles), plays a major role in the rate of ice sheet retreat.

Scientists now estimate that the circulation of seawater through the oceanic crust accounts for 34 % of the heat input into the global oceans, about 25 % of the globe's total heat input.

Just a general observation in regards to the oceanic heat content value in determining global warming.

Polar amplification, in which temperatures at the poles rise more rapidly than temperatures at the equator (due to factors like the global atmospheric and oceanic circulation of heat from the equator to the poles), plays a major role in the rate of ice sheet retreat.

Nature (with hopefully some constructive input from humans) will decide the global warming question based upon climate sensitivity, net radiative forcing, and oceanic storage of heat, not on the type of multi-decadal time scale variability we are discussing here.

So to you, when Dr. Maslowski said, «My claim is that the global climate models underestimate the amount of heat delivered to the sea ice by oceanic advection,» You think that he means a few outlier models instead of the main bulk of modeled knowledge?

Additionally the oceanic warming and cooling cycles introduce constant, rapid and substantial changes not yet reflected in any models and which invalidate any averaged global estimates of the planetary heat budget.

`'» My claim is that the global climate models underestimate the amount of heat delivered to the sea ice by oceanic advection,» Professor Maslowski said.»

In which case, half of the global warming in the last three decades is due to the negative feedback of increased poleward oceanic heat transport as a result of weaker solar activity.

On the 2000 meter depth graph over 2006 - 2014 of Poitou & Bréon, the yearly minima increased from 10 units to 16 units of 1022 J that is 0.41 W / m ²; but there is every year some oceanic heat storage during six months and a release of this heat the following six months: the maximum of the global outgoing longwave radiation is in July, shifted by 6 months w.r.t. the solar flux hat is maximum in January (1412 W / m ²) and minimum in July (1321 W / m ²).

After all CO2 is itself only a tiny portion of total greenhouse gases so that it can not have any significant long term effect when the water vapour primarily affecting atmospheric heat retention is in turn itself but a tiny proportion of global heat retaining capacity when one adds in the vastly greater oceanic heat retaining effect.

Our results show that repeated clusters of volcanic eruptions can induce a net negative radiative forcing that results in a centennial and global scale cooling trend via a decline in mixed - layer oceanic heat content.

A compelling case for geothermal forcing lies in the fact that 1) geothermal heat can trigger thermobaric convection and strengthen oceanic overturning, important mechanisms for transferring ocean heat to the overlying atmosphere, and 2) seismic activity is the leading indicator, while global temperature is the laggard.

The global oceanic conveyer belt, is a unifying concept that connects the ocean's surface and thermohaline (deep mass) circulation regimes, transporting heat and salt on a planetary scale.

The oceanic heat analysis above that lumps everything together, in the same way that global mean sea level analysis (from satellites), gives you a Computational Reality.
