«By processing the historical archive acquired by the Danish during the last century, they were able to provide an estimation of the ice sheet contribution to sea - level rise since 1900, which was critically missing in the last IPCC report,» noted Jeremie Mouginot, a climate scientist at the University of California, IrvinBy processing the historical archive acquired by the Danish during the last century, they were able to provide an estimation of the ice sheet contribution to sea - level rise since 1900, which was critically missing in the last IPCC report,» noted Jeremie Mouginot, a climate scientist at the University of California, Irvinby the Danish during the last century, they were able to provide an estimation of the ice sheet contribution to sea - level rise since 1900, which was critically missing in the last IPCC report,» noted Jeremie Mouginot, a climate scientist at the University of California, Irvine.

By Jim Steele A better accounting of natural groundwater discharge is needed to constrain the range of contributions to sea level rise.

2) There is debate about Antarctica's contribution to sea level rise as evidenced by — every paper about antarctica.

However, because they are partly submerged, their direct contribution to sea level rise is much smaller than the contribution made by the melting of an equivalent volume of (land - based) ice sheets.

For example, if this contribution were to grow linearly with global average temperature change, the upper ranges of sea level rise for SRES scenarios shown in Table SPM - 3 would increase by 0.1 m to 0.2 m. Larger values can not be excluded, but understanding of these effects is too limited to assess their likelihood or provide a best estimate or an upper bound for sea level rise.

Eric Rignot, a glaciologist at NASA's Jet Propulsion Laboratory, said, «None of this has been predicted by numerical models, and therefore all projections of the contribution of Greenland to sea level [rise] are way below reality.»

The main reason for assessing it at all is to inform inverse modelling methods — determining climatic sea level rise contribution by removing non-climatic contributors.

The IPCC projections of sea level rise are based largely on the slow, steady and inexorable thermal expansion of the oceans (as water heats, its volume increases) with some additional contributions from the melting of mountain glaciers (almost all of which are expected to be gone by mid century).

An international team of experts supported by NASA and the European Space Agency (ESA) has combined data from multiple satellites and aircraft to produce the most comprehensive and accurate assessment to date of ice sheet losses in Greenland and Antarctica and their contributions to sea level rise.

Warming might be the relevant factor, but we don't know the relative contributions by the different natural and anthropogenic components to warming, so saying that warming causes sea level rise doesn't give us much information.

Re: «Warming might be the relevant factor, but we don't know the relative contributions by the different natural and anthropogenic components to warming, so saying that warming causes sea level rise doesn't give us much information.»

This method concluded that there is a less than 1 - in - 20 risk of the contribution of ice sheets to global sea - level rise exceeding 84 cm by 2100.

The glaciers of West Antarctica are already responsible for the majority of the Antarctic continent's contribution to global sea level rise, and if these glaciers were to completely collapse, sea levels could rise by at least four feet, potentially inundating coastal cities around the world.

As he pointed out, a dominant unforced contribution to surface warming relative to forced trends would be expected to be accompanied by a trend of declining OHC, which is inconsistent with the observed trends averaged over the past half century as evidenced by mixed layer temperature measurements and sea level rise.

The United Nations Intergovernmental Panel on Climate Change (IPCC)'s worst projections for Greenland's contribution to sea level rise top out at 68 centimeters (27 inches) by the year 2100.

And more recent estimates of the Antarctic mass balance contribution to sea level rise has the East Antarctica ice sheet gaining mass at a more accelerated pace for 2003 - 2013 than the mere +14 Gt per year identified by Shepherd et al. (2012) for 1992 - 2011.

Cryospheric changes are described by Lemke et al. (2007), including the contribution of the cryosphere to sea - level rise.

According to the most highly - cited analyses of polar ice sheet melt and contribution to sea level rise, the Antarctic ice sheet as a whole changed in mass by -71 gigatonnes (GT) per year between 1992 and 2011.

An important contribution to present day sea level rise could result from changes in the amount of water stored in the ground, on the surface in lakes and reservoirs, and by modifications to surface characteristics affecting runoff or evapotranspiration rates.

Until recently, the contribution of ice sheets to sea - level rise remained unknown and is still debated, but the current acceleration of sea - level rise is attributed to heating of the oceans and melting of land glaciers which is supported by measurements of ocean temperatures and the behavior of mountain glaciers, the vast majority of which are retreating or exhibit signs of instability.

@ 1 Paul S. Most assessments of ice sheet contribution to sea level rise indicate an acceleration over the past decade, whereas altimeter - measured SLR has not been faster over the most recent decade There was a paper published within the last couple of years by some of this sites contributors that suggested part of the disparity may be due to an increase in land based water.

Update: This story was updated to clarify that the majority of ice loss in Antarctica each year is replaced by new snowfall; The amount of ice loss that is not replaced by snowfall is increasing, adding to the continent's contribution to global sea level rise.
