These lines were labelled «All SRES envelope including land ice uncertainty» in the TAR SPM and extended the range up to 88 cm, adding 18 cm at the top end.

Not exact matches

I further discount the 0.04 W / m ^ 2 (atmosphere and land and melted sea ice and land ice) mentioned in your research article as relatively minor given known uncertainties.

We contended here before that this is a bit of a leap, since there are other constraints on climate sensitivity (such as the last ice age) and other sources of uncertainty (solar, ozone, land use, etc.).

During recent years (1993 — 2003), for which the observing system is much better, thermal expansion and melting of land ice each account for about half of the observed sea level rise, although there is some uncertainty in the estimates.

The rate of 3mm / year is also roughly equivalent to the SLR budget from land ice melt and thermal expansion, though admittedly there is a lot of uncertainty specially about Antarctica.

There Is No Uncertainty Monster Multiple redundant surveys show plainly that global ice volume - on - land is decreasing without pause or obvious limit.

However the model structure, assumptions, and data assimilation methods, whatever their uncertainties and differences, are better than extrapolation or kriging over long distances or across land / sea / ice boundaries.

Inevitably there is great uncertainty, but the less influence you ascribe to thermal expansion the more land based ice you have to find to explain the rising sea level.

The inconclusive results stem from uncertainties in the model about how quickly the ice will slide over land and into the ocean, Payne says.

These partially offsetting effects lead to the expectation that direct human shifts in water storage on land will not have large effects on sea level in comparison to the effects of ocean warming and mountain - glacier and ice - sheet melting (Wada et al., 2012), although notable uncertainties remain in regards to future groundwater use and reservoir construction, and these effects vary considerably depending on the specific location (NRC, 2012e).

Predictions of sea ice changes will have large uncertainties without sustained observations; improved understanding of ice, ocean, land, and atmospheric processes; and advances in coupled and system models.

There are of course uncertainties in the estimation methods but independent data from multiple measurement techniques (explained here) all show the same thing, Antarctica is losing land ice as a whole, and these losses are accelerating quickly.
