Sentences with phrase «ice sheet response»

However, we do not know the functional form of ice sheet response to a large persistent climate forcing.

We find evidence in paleoclimate observations and in global climate simulations supporting the existence of amplifying feedback processes that would contribute to nonlinear ice sheet response.

Confirming these observations is a new paper showing Greenland ice sheet response is happening faster than scientists expected.

Recent accelerated rates of ice sheet melting and our current ignorance is cause for alarm given that «the destabilizing issue of comparable ocean and ice sheet response times is apparent».

Machens: Hansen (2007), assumed an ice sheet contribution of 1 cm for the decade 2005 — 15, with a potential ten year doubling time for sea - level rise, based on a nonlinear ice sheet response, which would yield 5 m this century.

The millennial (500-2000 year) time scale of deep ocean ventilation affects the time scale for natural CO2 change and thus the time scale for paleo global climate, ice sheet, and sea level changes, but this paleo millennial time scale should not be misinterpreted as the time scale for ice sheet response to a rapid large human - made climate forcing.

Greenland ice core data suggest that the Greenland ice sheet response to Eemian warmth was limited [91], but the fifth IPCC assessment [14] concludes that Greenland very likely contributed between 1.4 and 4.3 m to the higher sea level of the Eemian.

This sea level rise estimate is larger than that provided by the last IPCC report, but highlights the need for further research on ice sheet variablity and ice sheet response to climate change, both now and in the past.

The climate isn't done heating up, and ice sheet response is thought to be nonlinear, so there are multiple lines of reasoning which point to significant increase in the melt rate.

Ice sheet response to climate change is a problem where satellite observations may help.

Greenland ice core data suggest that the Greenland ice sheet response to Eemian warmth was limited [91], but the fifth IPCC assessment [14] concludes that Greenland very likely contributed between 1.4 and 4.3 m to the higher sea level of the Eemian.

However, we do not know the functional form of ice sheet response to a large persistent climate forcing.

Our atmosphere - ocean model shows that the freshwater spurs amplifying feedbacks that would accelerate ice shelf and ice sheet mass loss, thus providing support for our assumption of a nonlinear ice sheet response.
