Sentences with phrase «forced ice sheet growth»

Not exact matches

However, in the global mean, these changes sum to zero (or very close to it), and so the global mean sensitivity to global mean forcings is huge (or even undefined) and not very useful to understanding the eventual ice sheet growth or carbon cycle feedbacks.

Orbital forcing causes ice ages or ends them by redistributing incoming solar radiation over seasons and latitudes so that ice sheet growth or decay is more or less favorable on a regional basis, with a resulting global average albedo feedback.)

Other forcings, including the growth and decay of massive Northern Hemisphere continental ice sheets, changes in atmospheric dust, and changes in the ocean circulation, are not likely to have the same kind of effect in a future warming scenario as they did at glacial times.

«Changes in the CO2 and CH4 content have played a significant part in the glacial - interglacial climate changes by amplifying, together with the growth and decay of the Northern Hemisphere ice sheets, the relatively weak orbital forcing»

The growth and decay of continental ice sheets represents a slow feedback operating over millennia; if one is concerned with the more rapid response of the climate to CO2, ice sheets have to be accounted for as a major forcing.
