Sentences with phrase «ocean equilibrate»

Discrepancies in the glacial climate simulations are further amplified by short integration times, as the deep ocean equilibrates on millennial timescales.

Because the chemistry of the ocean equilibrates with that of the atmosphere (on time scales of decades to centuries), methane oxidized to CO2 in the water column will eventually increase the atmospheric CO2 burden (Archer and Buffett, 2005).

Not exact matches

That only after the atmosphere has «equilibrated» with THAT ocean, will the atmospheric temperature have peaked?

Alastair, the atmosphere equilibrates with the upper ocean whose CO2 / HCO3 - / CO32 - content is about the same size.

[OOOPS; this nonlinear effect puts their «alternative concept» into the realm of Trump administration «alternative facts» — BD] Although the deep ocean could dissolve 70 to 80 % of the expected anthropogenic carbon dioxide emissions and the sediments could neutralize another 15 % it takes some 400 years for the deep ocean to exchange with the surface and thousands more for changes in sedimentary calcium carbonate to equilibrate with the atmosphere.

Alastair, the atmosphere equilibrates with the upper ocean whose CO2 / HCO3 - / CO32 - content is about the same size.

After all, if average surface temperature is 15 C, wouldn't you expect land and ocean below the surface to equilibrate at roughly that temperature (with a slightly rising gradient to account for the flow of Earth's internal heat)?

If the ocean is too hot for life to fix calcium carbonate, or lacking in nutrients, saturation of bicarbonate will result and the process will equilibrates back toward gaseous CO2.

The CO2 concentration of the atmosphere is going up continuously, and so it invades the ocean as it equilibrates with warm surface waters.

However, a lot is not: instead it contributes to the overall warming of the deep ocean that has to occur for the climate system to equilibrate.

Solar forcing has increased over the 20th century and given that the oceans have not yet had time to equilibrate to the new levels of forcing, it must have contributed some to the recent warming, in fact, that equlibration was further delayed by the cooling period, so the unrealized climate commitment would have been greater than ordinarily expected given that most of the increase in solar activity occurred in the first half of the century.

The reasons are also based on the physics, which require that initial equilibration involves the rapidly equilibrating sinks in the ocean mixed layer and some terrestrial sources, while the overall decay rate that involves slower equilibration with larger sinks is much slower.

This makes sense because it takes time to equilibrate an excess of CO2 in the atmosphere with the ocean, and the shallow ocean responds faster than intermediate or deep water, so the ratio of the land to marine signals is therefore proportional to the carbon emissions rate.

I understand that bottom ocean does not equilibrate with 5000C of Earth crust because of slow mixing with colder water coming from arctic, as explained by michael sweet@11, thanks!.

Once the ocean has equilibrated to an impulse of CO2 with a half - life of ~ 5 years, both the ocean and the atmosphere have a higher level of carbon than they did before.

The reference to lack of warming from 1940 - 1970 suggests that he sees this lack of warming as an indication that the oceans had already equilibrated to the high level of solar forcing, but this conditional was not included in his original statement.

For example, the ocean temperature may have equilibrated by that time.

With an equilibrium climate sensitivity (ECS); fully equilibrating ocean temperatures requires thousands of years!

You use the land + ocean global temperature record, which ignores the fact that the oceans have not equilibrated to the current forcings including CFC.

Due to the ocean's buffering capacity and the biological pump, as seen in the graph below, the upper ocean can experience upwelling that drives CO2 levels to 3 times higher than what would be expected from equilibrating with the atmosphere.

That only after the atmosphere has «equilibrated» with THAT ocean, will the atmospheric temperature have peaked?

The only possible explanation for why the average temperature of the ocean is 4C is because that is the average surface temperature of the earth taken over a period of time long enough for convection and conduction to equilibrate the entire volume.

It's possible that the ocean would have equilibrated with atmospheric CO2, reducing the effect.

The way I interpret that is that the higher climate sensitivity must either involve different heat transfer modes / patterns, or that it involves a different temperature rise path, with more of the increase backloaded (ie if most of the increase for high sensitivity comes after 2070, then there's less time for the oceans to equilibrate than there would be, if most of the temperature increase was done by 2030).
