Sentences with phrase «also ice sheets models»

Also ice sheets models, as they become more realistic and are tested against observed ice sheet changes, may aid our understanding.

Not exact matches

The paper also describes an atmosphere - ocean modeling study of feedback loops caused by ice sheet melting under 2 °C conditions.

But the large volumes of data on Arctic sea and land ice that IceBridge has collected during its nine years of operations there have also enabled scientific discoveries ranging from the first map showing what parts of the bottom of the massive Greenland Ice Sheet are thawed to improvements in snowfall accumulation models for all of Greenlaice that IceBridge has collected during its nine years of operations there have also enabled scientific discoveries ranging from the first map showing what parts of the bottom of the massive Greenland Ice Sheet are thawed to improvements in snowfall accumulation models for all of GreenlaIce Sheet are thawed to improvements in snowfall accumulation models for all of Greenland.

The IPCC also predicts greater sea - level rise than it did in 2007, as it now includes models of ice - sheet movements.

As well as using a model to predict the future, we can also use it to reconstruct ice sheets in the past, giving clues as to the behaviour of the ice sheet in different climate settings.

Prognostic modelling can also involve reconstructing past ice sheets.

They also speak about sea level sensitivity as being higher than current ice sheet models show.

The differences are that the UVic model has a smaller forcing from the ice sheets, possibly because of an insufficiently steep lapse rate (5ºC / km instead of a steeper value that would be more typical of dryer polar regions), and also a smaller change from increased dust.

The periods considered were mainly the Pleistocene ice age cycles, the LGM and the Pliocene, but Paul Valdes provided some interesting modeling that also included the Oligocene, the Turonian, the Maastrichtian and Eocene, indicating the importance of the base continental configuration, ice sheet position, and ocean circulation for sensitivity.

They also speak about sea level sensitivity as being higher than current ice sheet models show.

Climate models also point to a more - likely - than - not probability that even greater impacts will result from feedback mechanisms such as permafrost and ice sheet melting beginning or accelerating, unleashing further warming.

The Budget also supports several research satellites currently in development, a campaign to monitor changes in polar ice sheets, and enhancements to climate models.

Such models also indicate that warming would initially cause the Antarctic ice sheet as a whole to gain mass owing to an increased accumulation of snowfall (*; some recent studies find no significant continent - wide trends in accumulation over the past several decades; Lemke et al., 2007 Section 4.6.3.1).

Current limitations of ice - sheet modelling also increase uncertainty in the projections of 21st - century sea - level rise (Meehl et al., 2007 Section 10.6.4.2) used to assess coastal impacts in this report.

Examples: Weertman (1976a)(Northwestern Univ., IL, and the U.S. Army Cold Regions Research and Engineering Laboratory, Hanover, NH); note also his pioneering calculation of ice sheet buildup and shrinkage times, Weertman (1964); Sergin (1979)(Laboratory for Mathematical Modeling of the Climate, Pacific Institute of Geography of Academy of Sciences, Vladivostok, but written while visiting NCAR, Boulder, CO); Budd and Smith (1981)(Meteorology Dept., U. Melbourne); as a perhaps more typical example, Young (1979)(Antarctic Division, Dept. of Science and Technology, Kingston, Tasmania) conservatively showed a response time of perhaps 20,000 years; an especially influential model involving ice sheet buildup delay was Imbrie and Imbrie (1980); a good review is Budd (1981).

The «boils» are also a dynamic effect which computer models of heated water pots might have missed — similar to ice sheet dynamics.

He is also deeply involved in ice - sheet modeling with specific developments in areas such as ice core dating and temperature reconstruction based on paleothermometry.
