Sentences with phrase «for global ice volume»

For instance, here's the data for delta - oxygen - 18 from a stack of 57 ocean sediment cores, which is considered an excellent proxy for global ice volume, known as the «LR04 stack» (from Lisiecki, L.E., & Raymo, M.E. 2005.

The stack of 57 globally distributed benthic δ18O marine records (dark grey), a proxy for global ice volume fluctuations (Lisiecki and Raymo, 2005), is displayed for comparison with the ice core data.

In a study published in the actual volume of Nature Communications, geo - and climate researchers at the Alfred - Wegener Institute, Helmholtz Centre for Polar - and Marine Research (AWI) show that, in the course of our planet's history, summertime sea ice was to be found in the central Arctic in periods characterised by higher global temperatures — but less CO2 — than today.

In some sense, the search for a theory of glacial - interglacial cycles amounts to a search for the «rectifier» which turns the modulation of the amplitude of the seasonal forcing into a rectified signal in global ice volume.

Global warming induced by increasing CO2 will cause ice to melt and hence sea level to rise as the global volume of ice moves toward the quasi-equilibrium amount that exists for a given global temperatureGlobal warming induced by increasing CO2 will cause ice to melt and hence sea level to rise as the global volume of ice moves toward the quasi-equilibrium amount that exists for a given global temperatureglobal volume of ice moves toward the quasi-equilibrium amount that exists for a given global temperatureglobal temperature [53].

With error bars provided, we can use the PIOMAS ice volume time series as a proxy record for reality and compare it against sea - ice simulations in global climate models.

Global climate model projections (in CMIP3 at least) appear to underestimate sea ice extent losses with respect to observations, though this is not universally true for all models and some of them actually have ensemble spreads that are compatible with PIOMAS ice volume estimates and satellite observations of sea ice extent.

The fact that our model does a surprisingly good job with simulating the last 400,000 years of global ice volume, with no change in model physics and only one linear change in boundary conditions, argues for the fact that, despite plausible deficiencies, we have done a surprisingly good job of simulating the pattern of fluctuations in ice volume.

For instance, if global warming were to increase the volume of water in the oceans by causing glaciers or other ice bodies to melt, this would cause the weight of water in the oceans to increase.

All of these characteristics (except for the ocean temperature) have been used in SAR and TAR IPCC (Houghton et al. 1996; 2001) reports for model - data inter-comparison: we considered as tolerable the following intervals for the annual means of the following climate characteristics which encompass corresponding empirical estimates: global SAT 13.1 — 14.1 °C (Jones et al. 1999); area of sea ice in the Northern Hemisphere 6 — 14 mil km2 and in the Southern Hemisphere 6 — 18 mil km2 (Cavalieri et al. 2003); total precipitation rate 2.45 — 3.05 mm / day (Legates 1995); maximum Atlantic northward heat transport 0.5 — 1.5 PW (Ganachaud and Wunsch 2003); maximum of North Atlantic meridional overturning stream function 15 — 25 Sv (Talley et al. 2003), volume averaged ocean temperature 3 — 5 °C (Levitus 1982).

The two - day FAMOS workshop will include sessions on 2017 sea ice highlights and sea ice / ocean predictions, reports of working groups conducting collaborative projects, large - scale arctic climate modeling (ice - ocean, regional coupled, global coupled), small (eddies) and very small (mixing) processes and their representation and / or parameterization in models, and new hypotheses, data sets, intriguing findings, proposals for new experiments and plans for 2018 FAMOS special volume of publications.

And since we have had rising sea level over last couple centuries, and this generally indicates warming global ocean volume, I expect this trend to continue for the next century [most likely] and due to warming oceans continuation of tread of less polar sea ice.

In some sense, the search for a theory of glacial - interglacial cycles amounts to a search for the «rectifier» which turns the modulation of the amplitude of the seasonal forcing into a rectified signal in global ice volume.

The Last Interglacial was also a period with higher global sea - level and a corresponding reduction in ice sheet area and volume, which are consistent with IPCC predictions for responses to future global warming.
