The Fighting Has Begun Over Who Owns Land Drowned by Climate Change: America’s coastal cities are preparing for legal battles over real estate that slips into the ocean

Houses along the flood zone in Dauphin Island, Ala. PHOTOGRAPHER: NICOLE CRAINE/BLOOMBERG By Christopher Flavelle, April 25, 2018, Bloomberg One April morning in 2016, Daryl Carpenter, a charter boat captain out of Grand Isle, La., took some clients to catch redfish on a marsh pond that didn’t use to exist. Coastal erosion and rising seas are submerging a football field’s worth of Louisiana land …

Avoid Gulf stream disruption at all costs, scientists warn

How close the world is to a catastrophic collapse of giant ocean currents is unknown, making halting global warming more critical than ever, scientists say By Damian Carrington, Environment editor, Guardian Fri 13 Apr 2018   Other research this week showed that Greenland’s massive ice cap is melting at the fastest rate for at least 450 years.

Disappearing polar ice setting off alarms: The short-term consequences of Arctic (and Antarctic) warming may already be felt in other latitudes. The long-term threat to coastlines is becoming even more dire.

By Daisy DUNNE, Carbon Brief , 2018 SEA ICE Limiting warming to 1.5C could ‘substantially’ cut risk of ice-free Arctic summers Meeting the Paris Agreement’s aspirational target of limiting global warming to 1.5C above pre-industrial levels could “substantially” reduce the risk of sea ice-free summers in the Arctic, research shows. Two new studies find that, under 1.5C of warming, Arctic waters could experience …

Security risk: retired admirals and generals say climate change is putting key military facilities at risk of costly damage that could knock out critical operations for weeks

Also, in this morning’s Washington Examiner, FedEx CEO Fred Smith and former Commandant of the Marine Corps, General James T. Conway, articulate both why and how to strike a deal that serves America’s interests. They write:  The reopening of the midterm evaluation of fuel efficiency standards has created an opportunity to strengthen and modernize the fuel economy regime. As technology offers a …

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 …

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 …
