Its formula can show how much of a threat sea - level rise poses to a property, giving homeowners, local governments and anyone else who uses the software a realistic picture of their future risk.

Geologist Torbjörn Törnqvist of Tulane University, a co-author of the study, said that given accelerating rates of sea level rise, losses will likely continue long into the future, and that even the best - designed river diversions won't be able to prevent more land loss.

Better estimates of Pliocene sea levels will help geologists know how much of the ice sheets melted during that balmy era, Dowsett says, which may give us a glimpse of our own climate future.

At the same time policymakers need to know the future of sea - level rise, and they need as robust a prediction as we can give,» said Michael Oppenheimer, Princeton's Albert G. Milbank Professor of Geosciences and International Affairs and the Princeton Environmental Institute and first author of the paper.

Kuhn, from Germany's Alfred Wegener Institute, added, «This gives confidence in the predictions of the current generation of ice sheet models which are used to forecast future ice loss from Antarctica and resulting sea - level rise.»

Given that the West Antarctic Ice Sheet has a total sea level equivalent of 3.3 m1, with 1.5 m from Pine Island Glacier alone4, marine ice sheet collapse could be a significant challenge for future generations, with major changes in rates of sea level rise being possible within just the next couple of hundred years.

So while times like the Eemian or Pliocene or Miocene may be interpreted as a warning call in some respects, it is not really good to determine threshold policy targets, or give substantial weight to answering big questions like future sea level change, based solely on these analogs.

Thus, given the delays in the system: both the ocean responding to CO (2), and the delays in humanity changing it's behavior, there is a risk of guaranteeing a future deglaciation of Greenland before drastic changes are observed (with the attendant O (7m) rise in sea level).

By «committed» or «locked in» warming or sea level in a given year, we refer to the long - term effects of cumulative anthropogenic carbon emissions through that year: the sustained temperature increase or SLR that will ensue on a time scale of centuries to millennia in the absence of massive and prolonged future active carbon removal from the atmosphere.

No of course it doesn't, But if the past tells us that ice sheets can break up quickly and sea levels rise quickly (for example) than this may give us insight into likely future system response.

Given the potential importance of West Antarctica to future global sea level and our current knowledge of glacier instability, why is there so much uncertainty about its future?

Eric Rignot (NASA / JPL) one of the world's most prominent glaciologists, who is behind a landmark report revealing the unstoppable collapse of a large part of Antarctica, gave a lecture at Victoria University of Wellington in February 2017, on future sea level rise.
