Global sea level could rise 50 feet by 2300, study says
Global average sea-level could rise by nearly 8 feet by 2100 and 50 feet by 2300 if greenhouse gas emissions remain high and humanity proves unlucky, according to a review of sea-level change and projections by Rutgers and other scientists. (2018-10-08)

Climate change puts hundreds of coastal airports at risk of flooding
Newcastle University scientists have found that 269 airports are at risk of coastal flooding now. A temperature rise of 2C - consistent with the Paris Agreement - would lead to 100 airports being below mean sea level and 364 airports at risk of flooding. If global mean temperature rise exceeds this then as many as 572 airports will be at risk by 2100, leading to major disruptions without appropriate adaptation. (2021-01-21)

What the past tells us about modern sea-level rise
Researchers from the University of Southampton and the Australian National University report that sea-level rise since the industrial revolution has been fast by natural standards and -- at current rates -- may reach 80 cm above the modern level by 2100 and 2.5 meters by 2200. (2013-12-12)

Ocean warming and thermal expansion will be the largest contributor to sea-level rise during the 21st century, says an Australian scientist. (2001-02-05)

Melting glaciers raise sea level
Anthropogenic climate change leads to melting glaciers and rising sea level. Between 1902 and 2009, melting glaciers contributed 11 cm to sea level rise. They were therefore the most important cause of sea level rise. This is the result of a new assessment by scientists of the University of Innsbruck. They numerically modeled the changes of each of the world's 300 000 glaciers. Until 2100, glaciers could lead to an additional 22 cm of sea level rise. (2012-11-14)

Larger variability in sea level expected as Earth warms

Significant sea-level rise in a 2-degree warming world
Even if global warming is limited to two degrees Celsius, global-mean sea level could continue to rise, reaching between 1.5 and four meters above present-day levels by the year 2300, with the best estimate being at 2.7 meters, according to a study just published in Nature Climate Change. However, emissions reductions that allow warming to drop below 1.5 degrees Celsius could limit the rise strongly. (2012-06-24)

Rising sea levels could cost the world $14 trillion a year by 2100
Failure to meet the United Nations' 2ºC warming limits will lead to sea level rise and dire global economic consequences, new research has warned.

(2018-07-03)

Under projected rates of sea level rise, a bleak future for Pacific coast tidal wetlands
Pacific coast marshes, particularly those in California and Oregon, are highly vulnerable to climate change, according to a new modeling analysis. Under higher-range sea level rise scenarios estimated to impact this region by the end of the century, all high- and mid-marsh habitats are projected to be lost. Only the low marsh habitat is likely to survive under such (2018-02-21)

New research from scientists at University of Hawai'i at Mānoa, Old Dominion University, and the NASA Jet Propulsion Laboratory shows that the longest and highest-quality records of historical ocean water levels may underestimate the amount of global average sea level rise that occurred during the 20th century. (2016-10-03)

Greenland ice sheet faces irreversible melting
Scientists predict Greenland ice sheet will pass a threshold beyond which it will never fully regrow and sea levels will be permanently higher in as little as 600 years under current climate change projections, as Greenland's climate would be permanently altered as the ice sheet shrinks. (2020-12-02)
