Not exact matches

So it would be nice for the climate models to have sufficient resolution to be able to predict the impact of changes in coastal sea ice.»

«These are two of the largest and most rapidly changing glaciers in Antarctica, so the potential for their evolution to influence each other is important to consider in modeling ice sheet behavior and projecting future sea level rise,» Dustin Schroeder, a Stanford geophysicist who led the study, told Earther.

In LGM simulations land albedo changes are prescribed (at least in regards to ice sheets and altered topography due to sea level; there are feedback land albedo changes) so are a forcing, whereas sea ice is determined interactively by the model climate, so is a feedback in this framework.

So to you, when Dr. Maslowski said, «My claim is that the global climate models underestimate the amount of heat delivered to the sea ice by oceanic advection,» You think that he means a few outlier models instead of the main bulk of modeled knowledge?

(The Pan-arctic Ice - Ocean Modeling and Assimilation System is part funded and info supplied by NASA... have they changed the measurement so that 1.5 % sea ice now treated as 100 % sea ice coveIce - Ocean Modeling and Assimilation System is part funded and info supplied by NASA... have they changed the measurement so that 1.5 % sea ice now treated as 100 % sea ice coveice now treated as 100 % sea ice coveice cover?)

From this small set, they applied the resulting model to the wider Greenland Ice Sheet, in order to work out the expected sea - level rise just from the most recent observed changes - and so figure out a «committed level of sea - rise».

The plan they came up with was to announce that (computer model - generated) predictions of sea ice decline due to (computer model - generated) predictions of human - caused global warming are so catastrophic that polar bears should be returned to their previous «vulnerable» classification, despite the fact that by all other criteria they are flourishing.

Climate models are like weather models for the atmosphere and land, except they have to additionally predict the ocean currents, sea - ice changes, include seasonal vegetation effects, possibly even predict vegetation changes, include aerosols and possibly atmospheric chemistry, so they are not like weather models after all, except for the atmospheric dynamics, land surface, and cloud / precipitation component.

So what does the 0 - dimensional energy - balance model predict about heat - waves in Australia, the decay of Arctic sea ice and Amazonian precipitation?

Billions are being spent on all sorts of peripheral work or sea levels, Arctic sea ice extent, etc. as well as model studies on CAGW, so why is no one working on the basics?

Another month has passed and so here is the updated Arctic sea ice volume graph as calculated by the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) at the Polar Science Centice volume graph as calculated by the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) at the Polar Science CentIce Ocean Modeling and Assimilation System (PIOMAS) at the Polar Science Center:

Direct measurements of the AMOC are only available for the past ten years or so, but Yeager et al. present a combination of observation - and model - based evidence that suggests that the Atlantic thermohaline circulation (THC, which is closely related to AMOC) transitioned from a weak state in the 1970s to a strong state in the 1990s and that this strengthening contributed to the accelerated rate of winter sea ice loss that was observed in the late 1990s.

1 — did the circulation - driven fall in Arctic sea ice (which AR4 models don't do a great job of) have anything to do with the recent jump in Arctic temperatures and if so, could we get the «right» global temp trend for the «wrong» reasons.

Dekker (Public), 4.60, (4.15 - 5.05 standard deviation range), Statistical Arctic sea ice decline has global implications for Northern Hemisphere weather patterns and Arctic eco systems and wild life alike, and thus it is concerning that our global climate models so far appear to underestimate the observed rate of decline based on albedo amplification of sea ice alone.

So it's possible that shrinking sea ice in the Arctic could increase snowfall over Siberia, pushing the jet stream southward, creating summer high pressures in Europe that allow India's monsoon rains to linger, and on it goes... It's hard to examine those connections in the real world, but it's much easier to see how things play out in a climate model.

Clearly, therefore, something must be fundamentally wrong with the climate models, for their predictions to be so far off from the observed sea ice trends.»

CO2 is a small fraction of sea level gases, so far all models, calculations do not include water vapour or particulates which act in the atmosphere and in reducing the ice cap / snoe level albido effect.

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.

That settling down into a more stable and truely predictable state will only ocme about by the overwhelming obviousness of the first hand experiences and events as they unfold and are once more creating louder headlines in the media than the so called scandals are now... i.e. new record lows in sea ice, record highs in global temps, and other extremes predicted by AGW models.

Current sea ice modules don't explicitly model melt ponds, so they parameterize in some way the melting ice albedo, the simplest parameterization being setting the melting ice albedo to be constant.
