New Research Confirms ‘Catastrophic’ Climate Threat: Global Sea Levels Could Rise 174 Feet From Melting East Antarctic Ice Sheet

By Tim Radford, EcoWatch Dec 18 2017 New research has confirmed one of the worst nightmares of climate science: the instability of the East Antarctic ice sheet. This vast mass holds enough water to raise sea levels by 53 meters (approximately 174 feet) worldwide. And researchers have confirmed that one stretch of the southern polar coastline has melted many times in the past: by enough to …

Global sea levels could rise ‘up to five metres’ if certain Antarctic ice sheets melt

New evidence suggests East Antarctic glaciers are not as stable as scientists have long assumed, which ‘has some worrying implications for future sea level changes’ by Josh Gabbatiss Science Correspondent, 14 Dec 2017 The Independent Online If East Antarctic ice sheets melt, they could play a significant role in sea level rises AFP An Antarctic ice sheet found to be less resistant to warming temperatures …

Sea level rise and city flooding update

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 …
