Sentences with phrase «occur during deglaciations»

The sharpest methane concentration increases occur during deglaciations, in phase with Greenland (NH) temperature and monsoon intensity increases.

There is considerable spatial and temporal structure in how the changes occur during deglaciation.

It is important to realize that the nature of CO2's lead / lag relationship with Antarctica is insightful for our understanding of carbon cycle dynamics and the sequence of events that occur during a deglaciation, but it yields very little information about climate sensitivity.

Not exact matches

The experiment simulated conditions believed to be the cause of the beveling — the most recent episode of which occurred during the period of deglaciation following the last Ice Age, about 18,000 years ago.

And remember, during deglaciations, outgassing from the oceans would have occurred in a context in which warming was occurring, but not an exogenous increase in atmospheric CO2 — and outgassing (or not!)

The data rule out methane hydrates as a major contributor to (i) glacial - interglacial variations during the last deglaciation, and (ii) millennial methane increases that occur in phase with Greenland temperature abrupt events.

Rapid steps of 2 m / cy [20 mm / yr] also occurred during previous deglaciations.

Here, we review terrestrial evidence for changes in ice geometry that occurred in the Ross Sea sector of Antarctica at the Last Glacial Maximum (LGM) and during subsequent deglaciation.

It is likely that large rapid decadal temperature changes occurred during the last glacial and its deglaciation (between about 100,000 and 10,000 years ago), particularly in high latitudes of the Northern Hemisphere.

In addition, instead of being gradual (several millennia), nearly half of the ~ 85ppm rise in CO2 during the deglaciation occurred in three abrupt 10 - 15ppm steps that took place in less than 100 - 200 yrs and were followed by concentration plateaus.
