Coastal resiliency researchers awarded $1.3 million in grants
Nearly a quarter of the world's population lives within 60 miles of the shoreline and within 300 feet of sea level elevation. As sea level rises, these shoreline communities as well as barrier islands, dunes and marshes become more at-risk. The LSU Center for Coastal Resiliency, or CCR, has received $1.3 million in grants to support critical research that will advance the tools and processes to assess these risks. (2016-11-04)

Climate balancing: Sea-level rise vs. surface temperature change rates
Engineering our way out of global climate warming may not be as easy as simply reducing the incoming solar energy, according to a team of University of Bristol and Penn State climate scientists. Designing the approach to control both sea level rise and rates of surface air temperature changes requires a balancing act to accommodate the diverging needs of different locations. (2012-01-18)

Their research appears in the September issue of Frontiers in Ecology and the Environment. (2005-09-22)

Global sea-rise levels by 2100 may be lower than some predict, says CU-Boulder study
Despite projections by some scientists of global seas rising by 20 feet or more by the end of this century as a result of warming, a new University of Colorado at Boulder study concludes that global sea rise of much more than 6 feet is a near physical impossibility. (2008-09-04)

How much will polar ice sheets add to sea level rise?
Over 99% of terrestrial ice is bound up in the ice sheets covering Antarctic and Greenland. Even partial melting of this ice due to climate change will significantly contribute to sea level rise. But how much exactly? For the first time ever, glaciologists, oceanographers, and climatologists from 13 countries have teamed up to make new projections. (2020-09-17)

UM researcher proposes sea-level rise global observing system
University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science researcher Shane Elipot proposes a new approach to monitoring global sea-level rise. Using the existing NOAA Global Drifter Program array of roughly 1,200 buoys that drift freely with ocean currents, Elipot suggests adding additional instruments to record their height, or the ''level of the sea'' they ride on, to collect long-term data on the average sea levels across the world's oceans. (2020-10-26)

Melting small glaciers could add 10 inches to sea levels
A new review of glacier research data paints a picture of a future planet with a lot less ice and a lot more water.

'Noah's flood' kick-started European farming
The flood believed to be behind the Noah's Ark myth kick-started European agriculture. This research paper assesses the impact of the collapse of the North American (Laurentide) Ice Sheet, 8,000 years ago. The results indicate a catastrophic rise in global sea level led to the flooding of the Black Sea and drove dramatic social change across Europe. The research team argues that, in the face of rising sea levels driven by contemporary climate change, we can learn important lessons from the past (2007-11-18)

More ice loss through snowfall on Antarctica
Stronger snowfall increases future ice discharge from Antarctica. Global warming leads to more precipitation as warmer air holds more moisture -- hence earlier research suggested the Antarctic ice sheet might grow under climate change. Now a study published in Nature shows that a lot of the ice gain due to increased snowfall is countered by an acceleration of ice-flow to the ocean. (2012-12-12)

Global climate change: Underestimated impact of sea-level rise on habitat loss?
Global climate change is expected to cause sea-level rise of approximately 1-2 meters within this century. Researchers from the Konrad Lorenz Institute of Ethology of the University of Veterinary Medicine, Vienna and colleagues from Aarhus University, Denmark, found that in more populated regions secondary effects can lead to an equal or even higher loss of habitat than primary displacement effects. The results are published in the new issue of the international journal Global Change Biology. (2012-06-13)
