It is the reversal of the global warming trend that would appear to be being called for within the 10 - year window, the «prediction'that «entire nations could be wiped off the face of the Earth by rising sea levels» (and note the «could» in there) isn't within that timespan.

They start from the premise that global mean sea level rise will continue beyond 2100, and from the prediction that for every 1 °C of climate warming, humans should expect an eventual 2.3 metre rise in sea levels.

This prediction was seized upon by global warming advocates as «proof» that the South Pole's unprecedented warming would melt sea ice and cause melting ice sheets to collapse, raising ocean levels and thus submerging worldwide coastal areas.

So, they didn't actually simulate sea level changes, but instead estimated how much sea level rise they would expect from man - made global warming, and then used computer model predictions of temperature changes, to predict that sea levels will have risen by 0.8 - 2 metres by 2100.

This is the basis for the first theoretical prediction for the effects of global warming mentioned in Section 1 — if global warming causes the oceans to heat up, this should (in theory) cause sea levels to rise, from «thermal expansion».

J. T. Fasullo, R. S. Nerem & B.

We must maintain and extend the existing global climate observing systems [Riser et al., 2016; von Schuckmann et al., 2016] as well as develop improved coupled (ocean - atmosphere) climate assessment and prediction tools to ensure reliable and continuous monitoring for Earth's energy imbalance, ocean heat content, and sea level rise.

Global warming may not affect sea levels, study finds — January 11, 2008 Excerpt: Excerpt: The most pessimistic predictions of sea level rises as ice sheets are melted by global warming may have to be scaled back as a result of an extraordinary discovery that ice persisted when the Earth was much hotter than Global warming may not affect sea levels, study finds — January 11, 2008 Excerpt: Excerpt: The most pessimistic predictions of sea level rises as ice sheets are melted by global warming may have to be scaled back as a result of an extraordinary discovery that ice persisted when the Earth was much hotter than global warming may have to be scaled back as a result of an extraordinary discovery that ice persisted when the Earth was much hotter than today.

The measurement of long - term changes in global mean sea level can provide an important corroboration of predictions by climate models of global warming.

«The CCR - II report correctly explains that most of the reports on global warming and its impacts on sea - level rise, ice melts, glacial retreats, impact on crop production, extreme weather events, rainfall changes, etc. have not properly considered factors such as physical impacts of human activities, natural variability in climate, lopsided models used in the prediction of production estimates, etc..

The IPCC 2007 Fourth Assessment of climate change science concluded that large reductions in the emissions of greenhouse gases, principally CO2, are needed soon to slow the increase of atmospheric concentrations, and avoid reaching unacceptable levels.However, climate change is happening even faster than previously estimated; global CO2 emissions since 2000 have been higher than even the highest predictions, Arctic sea ice has been melting at rates much faster than predicted, and the rise in the sea level has become more rapid.

Chief among those is what policy makers will actually do with a document that voices concern over climate change with even stronger language than before, and with greater resolution on predictions about global sea - level rise.

One hears of dire predictions of sea - level rises which don't seem to be eventuating, of stasis in global temperatures that weren't predicted, of claimed ad - hoc appeals to aerosol effects, etc., and that's without going into the general atmosphere of hostility to people like me who genuinely think the case for harmful AGW effects looks shaky.

Global sea level data shows that sea level rise has been increasing since 1880 while future sea level rise predictions are based on physics, not statistics.

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.

Indeed, working with predictions for future temperature increases and glacier melt rates generated by ten separate global climate models — all of which are also used by the Intergovernmental Panel of Climate Change - the team have concluded that these smaller ice sources will contribute around 12 centimetres to world sea - level increases over the remainder of the century, with this likely to have catastrophic consequences for numerous natural habitats as well as for hundreds of thousands of people.
