Sentences with phrase «sea ice modelled within»

Not exact matches

Computer model simulations have suggested that ice - sheet melting through warm water incursions could initiate a collapse of the WAIS within the next few centuries, raising global sea - level by up to 3.5 metres.»

We quantify sea - level commitment in the baseline case by building on Levermann et al. (10), who used physical simulations to model the SLR within a 2,000 - y envelope as the sum of the contributions of (i) ocean thermal expansion, based on six coupled climate models; (ii) mountain glacier and ice cap melting, based on surface mass balance and simplified ice dynamic models; (iii) Greenland ice sheet decay, based on a coupled regional climate model and ice sheet dynamic model; and (iv) Antarctic ice sheet decay, based on a continental - scale model parameterizing grounding line ice flux in relation to temperature.

This is starting to make the second graph (below) looking reasonable, and those scientists and models which have been suggesting an sea - ice - free summer Arctic within a decade to be on the money.

The current operational ensemble forecast systems model sea ice dynamically using the LIM2 model within NEMO ocean model to represent the dynamic and thermodynamic evolution of sea ice within the coupled forecast system.

In addition, chosen models had to simulate (hindcast), within 20 % accuracy, September sea ice extent observed from 1980 to 1999.

RCP 2.6 and a realistic model based on past sea ice extent and its relationship to AMO are indistinguishable and do not anticipate an Arctic free of ice within the 21st century if current trends are maintained.

«Using complex new modeling, the scientists have found that rapidly melting Arctic sea ice now threatens to diminish precipitation over California by as much as 15 percent within 20 to 30 years,» the Los Angeles Times writes.

A sea ice free summer arctic within 30 years: an update from CMIP5 models.

Within the Outlook project, there may be differences in how each group obtains their area (e.g., model grid cells of varying resolution, sea ice charts, and satellite observations); each of these could produce a different value for ice extent.

As sea ice declines, it becomes thinner, with less ice build - up over multiple years, and therefore more vulnerable to further melting.15 Models that best match historical trends project northern waters that are virtually ice - free by late summer by the 2030s.25, 26,12 Within the general downward trend in sea ice, there will be time periods with both rapid ice loss and temporary recovery, 27 making it challenging to predict short - term changes in ice conditions.

Wang, M., and J. E. Overland, 2012: A sea ice free summer Arctic within 30 years: An update from CMIP5 models.

Given that the IPCC models significantly underestimate the observed rate of Arctic sea - ice decline (17), a summer ice - loss threshold, if not already passed, may be very close and a transition could occur well within this century.

They may result from more tuning of sea ice conditions within the models, improved model parameterizations and processes, or some combination of the two.

Using a model that tracked a range of habitat conditions, including water temperature and depth from sea ice, to predict which habitats would be most impacted by climate change, William Cheung, the study's lead author, and his colleagues found that around 50 species of commercial fishes living near or at the poles will go extinct within the next 4 decades.
