Properties exposed to rising sea levels sell at a 7% discount to comparable properties not subject to climate-related risk

By David Morris, 21 Apr 2018, Fortune.com, Climate Change Is Already Depressing the Price of Flood-Prone Real Estate New research shows that real estate properties in areas affected by extreme weather and sea level rise are losing value relative to less exposed properties. The effects are already substantial, but they may point to a looming collapse as climate change makes coastal communities untenable. …

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.

CREDIT: MICHAEL BOCCHIERI/GETTY IMAGES New research provides strong evidence that one of the long-predicted worst-case impacts of climate change — a severe slow-down of the Gulf Stream system — has already started. The system, also known …

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 …

NYC can expect a Hurricane Sandy-like flood every 5 years if we turn around fossil fuel use now (1.5 C) or three per decade if temps rise around 2 C

The study found that New York City can expect two Hurricane Sandy-like floods per decade by the year 2100 if global temperatures rise 1.5 degrees Celsius above pre-industrial levels, and three such events per decade if temperatures rise to 2.0 and 2.5 C. Credit: DJ Rasmussen, Princeton University The 2015 Paris climate agreement sought to stabilize global temperatures by limiting …

Floods Are Getting Worse, and 2,500 Chemical Sites Lie in the Water’s Path

New York Times, By Hiroko Tabuchi et al., 6 Feb 2018 Anchored in flood-prone areas in every American state are more than 2,500 sites that handle toxic chemicals, a New York Times analysis of federal floodplain and industrial data shows. About 1,400 are located in areas at highest risk of flooding. As flood danger grows — the consequence of a …

Hurricane Harvey studies: Yesterday’s 100-year storm is today’s 30-year storm

SCOTT K. JOHNSON – 12/17/2017, Ars Technica Enlarge Texas Military Department 104 The story explaining the incredible flooding in Houston during Hurricane Harvey has many chapters, ranging from meteorology to the history of groundwater use and development zoning. The chapter on climate change has already had a few pages filled in, thanks to a study quickly published by MIT hurricane scientist Kerry Emanuel. This week, …

Worst Case Effects of Hurricanes, Flooding, High Tides, and Sea Level Rise on DelDOT Assets

Delaware DOT and the University of Delaware, 2017 Draft Objectives What are the worst case effects of hurricanes, riverine flooding, high tides, and sea level rise inundation on DelDOT’s assets? The University of Delaware Water Resources Center (UDWRC) and Center for Applied Demography and Survey Research (CADSR) utilized climatic, hydrologic, hydraulic, and geographic information systems (GIS) data to document and …
