Sentences with phrase «change during deglaciation»

He thinks that we can look to paleoclimate as evidence for abrupt climate change — and indeed we can — but the examples he has to use are those of abrupt change during deglaciation (YD) or during glacial climate (D - O; Heinrich; Bond).

Not exact matches

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

«Sudden Changes in North Atlantic Circulation During the Last Deglaciation.»

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.

Ice albedo feedback change is mainly limited to high latitude NH * land * during deglaciation, and its effects — though strong — are limited compared to those of a radiative forcing over the global ocean.

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.

Centennial - scale changes in the global carbon cycle during the last deglaciation.

These rapid changes in atmospheric CO2 and CH4 concentrations are also recorded during the Heinrich Stadials of MIS 3, demonstrating an important mechanism that operates on centennial time scales during the glacial and deglaciation, which may point to important thresholds in the global carbon cycle.

Of the two, temperature changes are thought to be most important, both during the last deglaciation (Mienert et al., 2005) and also in the future.

Internal conditions change, orbital forcing roughly constant during (relatively brief) duration of YD, global average temperature barely changes despite major albedo increase, YD ends, deglaciation continues apace...

[Response: Turns out that hydrate preservation is much more sensitive to changes in temperature than it is changes in pressure, so what we might look for is release of methane during deglaciation.

Actually, by the time you approach 200ppmv for CO2, you have already reached the break point in the curve, beyond which additional CO2 has much less impact on the RF — and this is close to the glacial value — suggesting that CO2 changes do not drive the glacial cycles (CO2 changes are supposed to amplify T rise during deglaciation, but there is scant evidence for this and the assumption that it did also underlay the IPCC belief — and a great many references in academic papers give a T degrees C per ppmv CO2 without stating over which range of concentrations this is meant to apply.
