Other communities are already facing this disruptive reality.  http://www.ucsusa.org/global-warming/global-warming-impacts/when-rising-seas-hit-home-chronic-inundation-from-sea-level-rise#.Wf-uCGhSxaQ https://www.theguardian.com/cities/ng-interactive/2017/nov/03/three-degree-world-cities-drowned-global-warming Scientists estimate that 275 million people worldwide live in areas that will eventually be flooded at 3C …

Massive storms and Western Atlantic sea level rise resulted from slightly warmer temperatures and moderate CO2 concentrations over a hundred thousand years ago

Geologic evidence is the forerunner of ominous prospects for a warming Earth, October 12, 2017, Science Daily While strong seasonal hurricanes have devastated many of the Caribbean and Bahamian islands this year, geologic studies on several of these islands illustrate that more extreme conditions existed in the past. A new analysis shows that the limestone islands of the Bahamas and …

New study confirms accelerating sea level rise

By Darien Kaufman in Mashable, 26 June 2017 A new study, published in June in the journal Nature Climate Change, confirms an acceleration in sea level rise during the past few decades. There had been greater uncertainty about this before, with climate deniers latching onto that and arguing that such an acceleration has not, in fact, been occurring. However, by …

Rising seas could result in 2 billion refugees by 2100

Cornell University, 26 June 2017, Science Daily Street under flood waters, Bangkok, Thailand. In the year 2100, 2 billion people — about one-fifth of the world’s population — could become climate change refugees due to rising ocean levels. Those who once lived on coastlines will face displacement and resettlement bottlenecks as they seek habitable places inland, according to Cornell University …

Coastal cities could flood three times a week by 2045

By John Updike, 9 Feb 2017, Originally published on Climate Central The lawns of homes purchased this year in vast swaths of coastal America could regularly be underwater before the mortgage has even been paid off, with new research showing high tide flooding could become nearly incessant in places within 30 years. Such floods could occur several times a week …

West Antarctic Ice Sheet forming rifts, calving 20 miles inland

By Tim Radford, Climate News Network, 21 Dec 2016 Scientists in the U.S. have identified an ominous trend in the Southern Ocean—the creation of enormous icebergs as rifts develop in the shelf ice many miles inland.  The first sign of a fracture 20 miles inland was seen in 2013. Two years later, the rift became complete and the 580 sq km …

More emission reductions needed to avoid Arctic melting, says AMAP chair

“It is… clear that the pledges given at COP21 will not be sufficient to stop the ongoing climate change processes in the Arctic. Recent climate modelling shows that more stringent commitments are therefore needed,” Martin Forsius from the Arctic Monitoring and Assessment Programme (AMAP) said. The AMAP chair urged for more emission reductions, adding that reaching the COP21 target of …
