Sentences with phrase «ice sheet models predicted»

Forecasts of future ice sheet behavior appear even more uncertain: Under the same high — global warming scenario, eight ice sheet models predicted anywhere between 0 and 27 cm of sea level rise in 2100 from Greenland melt.

This is despite using observed ice sheet mass loss (0.19 mm / year) in the «modelled» number in this comparison, otherwise the discrepancy would be even larger — the ice sheet models predict that the ice sheets gain mass due to global warming.

Not exact matches

In other words, the losses of mass of the West Antarctic Ice Sheet will intensify — just like the models predict.»

The consequences of global sea level rise could be even scarier than the worst - case scenarios predicted by the dominant climate models, which don't fully account for the fast breakup of ice sheets and glaciers, NASA scientists said today (Aug. 26) at a press briefing.

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

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

Constraints such as these are important for numerical models that attempt to replicate and predict the past and future behaviour of the Antarctic Ice Sheet.

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.

Pine Island Glacier (PIG) in West Antarctica is a good example of the value of both prognostic and diagnostic modelling in understanding and predicting ice sheet behaviour.

Joughin et al. (2010) applied a numerical ice sheet model to predicting the future of PIG, their model suggested ongoing loss of ice mass from PIG, with a maximum rate of global sea level rise of 2.7 cm per century.

Models actually predict that the interior of the ice sheets should gain mass because of the increased snowfall that goes along with warmer temperatures, and recent observations actually agree with those predictions.

For example, this one at the NY Times: Climate Model Predicts West Antarctic Ice Sheet Could Melt Rapidly.

These results confirm behaviour predicted by climate models showing that greater snow cover should occur in this ice sheet.

Now, if what you really mean is that the models used to predict ice - sheet fluctuations were off, then we can start talking from there.

But what the GSL now says is that geological evidence from palaeoclimatology (studies of past climate change) suggests that if longer - term factors are taken into account, such as the decay of large ice sheets, the Earth's sensitivity to a doubling of CO2 could itself be double that predicted by most climate models.

Hansen et al. recently explored the effect of stratification of meltwater water on storminess, sea surface temperature and sea level rise and found that, among other things, their model predicted strong feedbacks in ice sheet exposure to destabilizing influences.

And were the models earlier (say 10 years ago) predicting the current speed at which the Greenland ice sheets are melting?

It suggests that current ice sheet modeling studies are too simplistic to accurately predict the future contributions of the entire Greenland Ice Sheet to sea level rise, and that Greenland may lose ice more rapidly in the near future than previously thougice sheet modeling studies are too simplistic to accurately predict the future contributions of the entire Greenland Ice Sheet to sea level rise, and that Greenland may lose ice more rapidly in the near future than previously thosheet modeling studies are too simplistic to accurately predict the future contributions of the entire Greenland Ice Sheet to sea level rise, and that Greenland may lose ice more rapidly in the near future than previously thougIce Sheet to sea level rise, and that Greenland may lose ice more rapidly in the near future than previously thoSheet to sea level rise, and that Greenland may lose ice more rapidly in the near future than previously thougice more rapidly in the near future than previously thought.

Mengel's team projected future sea levels by combining the results of models that anticipate changes to icebergs, ice sheets and ocean expansion in the years ahead, and used those findings to predict sea levels.

Another eminent glaciologist, Aslak Grinsted, of the Centre for Ice and Climate at the University of Copenhagen, says the IPCC did not provide an «explicitly» higher estimate of sea - level rise over the next century «because we do not have models that reliably can predict how probable a collapse of the Antarctic ice sheet Ice and Climate at the University of Copenhagen, says the IPCC did not provide an «explicitly» higher estimate of sea - level rise over the next century «because we do not have models that reliably can predict how probable a collapse of the Antarctic ice sheet ice sheet is.

Research on crevasses in the Greenland ice sheet may help scientists build better computer models to predict the impact of ice bodies on rising sea levels.

Geological evidence from studies of past climate change now suggests that if longer term factors are taken into account, such as the decay of large ice sheets and the operation of the full carbon cycle, the sensitivity of the Earth to a doubling of CO2 could be double that predicted by most climate models.

«The IPCC did not provide an «explicitly» higher estimate of sea - level rise over the next century «because we do not have models that reliably can predict how probable a collapse of the Antarctic ice sheet is.

Such solecisms throughout the IPCC's assessment reports (including the insertion, after the scientists had completed their final draft, of a table in which four decimal points had been right - shifted so as to multiply tenfold the observed contribution of ice - sheets and glaciers to sea - level rise), combined with a heavy reliance upon computer models unskilled even in short - term projection, with initial values of key variables unmeasurable and unknown, with advancement of multiple, untestable, non-Popper-falsifiable theories, with a quantitative assignment of unduly high statistical confidence levels to non-quantitative statements that are ineluctably subject to very large uncertainties, and, above all, with the now - prolonged failure of TS to rise as predicted (Figures 1, 2), raise questions about the reliability and hence policy - relevance of the IPCC's central projections.

His citation is a newspaper article «Climate Model Predicts West Antarctic Ice Sheet Could Melt Rapidly» by Justin Gillis, New York Times, March 30, 2016.

That was a key point of Part I of this post; that in the real world, key climate change impacts — sea - ice loss, ice - sheet melting, temperature, and sea - level rise — are all either near the top or actually in excess of their values as predicted by the IPCC's climate models.

We conclude that the ice sheet surface is efficiently drained under optimal conditions, that digital elevation models alone can not fully describe supraglacial drainage and its connection to subglacial systems, and that predicting outflow from climate models alone, without recognition of subglacial processes, may overestimate true meltwater release from the ice sheet.

The fundamental data sets produced by the icePod system are necessary to support the development of accurate ice sheet models to predict sea level rise.
