Sentences with phrase «global oceanic cycles»

It seems to the writer that spreading global oceanic cycles of up to 30 years in length across 3 solar cycles results in a close enough match to fit temperature observations over the past few hundred years and especially since 1961.

Not exact matches

Unicellular photosynthetic microbes — phytoplankton — are responsible for virtually all oceanic primary production, which fuels marine food webs and plays a fundamental role in the global carbon cycle.

Mouchet, A., and L. François, 1996: Sensitivity of a global oceanic carbon cycle model to the circulation and to the fate of organic matter: Preliminary results.

Our findings have significance for global carbon cycling, oceanic carbon sequestration, and the cellular biology of coccolithophores.

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.

Climate contrarian geologist Don Easterbook has been predicting impending global cooling since 2000, based on expected changes in various oceanic cycles (including ENSO) and solar activity.

It logically follows that, from time to time, the other oceanic cycles can operate in conjunction with PDO / ENSO to emphasise the effect on the global temperature.

Before it is safe to attribute a global warming or a global cooling effect to any other factor (CO2 in particular) it is necessary to disentangle the simultaneous overlapping positive and negative effects of solar variation, PDO / ENSO and the other oceanic cycles.

On balance the evidence shows that solar and oceanic variations are more likely the cause of recent observations of warming in the air than increasing CO2 in the air but the issue can soon be resolved by observing the global air temperature changes that occur during and after the extended cycle 23 and the probable weak cycle 24.

[17] A 1500 year cycle corresponding to the North Atlantic oceanic circulation may have widespread global distribution in the Late Holocene.

The most likely candidate for that climatic variable force that comes to mind is solar variability (because I can think of no other force that can change or reverse in a different trend often enough, and quick enough to account for the historical climatic record) and the primary and secondary effects associated with this solar variability which I feel are a significant player in glacial / inter-glacial cycles, counter climatic trends when taken into consideration with these factors which are, land / ocean arrangements, mean land elevation, mean magnetic field strength of the earth (magnetic excursions), the mean state of the climate (average global temperature), the initial state of the earth's climate (how close to interglacial - glacial threshold condition it is) the state of random terrestrial (violent volcanic eruption, or a random atmospheric circulation / oceanic pattern that feeds upon itself possibly) / extra terrestrial events (super-nova in vicinity of earth or a random impact) along with Milankovitch Ccycles, counter climatic trends when taken into consideration with these factors which are, land / ocean arrangements, mean land elevation, mean magnetic field strength of the earth (magnetic excursions), the mean state of the climate (average global temperature), the initial state of the earth's climate (how close to interglacial - glacial threshold condition it is) the state of random terrestrial (violent volcanic eruption, or a random atmospheric circulation / oceanic pattern that feeds upon itself possibly) / extra terrestrial events (super-nova in vicinity of earth or a random impact) along with Milankovitch CyclesCycles.

Since 2009, US CLIVAR has collaborated with the OCB Program, whose mission is to study the impact of oceanic variability in the global carbon cycle in the face of environmental variability and change.
