As the planet warms, the ocean absorbs heat trapped by greenhouse gases, causing some of the expansion behind sea level rise. A map showing sea level rise scenarios and affected properties and infrastructure in Boston. The data in MORIS show current mean higher high water plus one foot increments of sea level rise up to six feet. This viewer includes interactive maps of flooding extents and water level elevations associated with sea level rise scenarios, current coastal flood zones, and hurricane surge modeled by the National Oceanic and Atmospheric Administration (NOAA), Federal Emergency Management Agency (FEMA), and U.S. Army Corps of Engineers (USACE). Continued growth of greenhouse gas emissions and associated global warming could well promote SLR of 1m in this century, and unexpectedly rapid breakup of the Greenland and West Antarctic ice sheets might … By overlaying social and economic data on a map that depicts sea level rise, a community can see the potential impact that sea level rise can have on vulnerable people and businesses. Users can simulate inundation associated with one to six feet of sea level rise at various scales along the contiguous United States coast, except for the Great Lakes. In the “FEMA Coastal Flood Zones” tab, water levels are included with the flood zone labels on the map. "But we also know that there are towns, like Revere, where they are kind of solidly working class places… [which have] some combination of a low-lying topography, relatively dense population and a concentration of homes that are valued below the state median.”. Dahl said racial disparities in homes threatened by sea level rise exist in some parts of the country — particularly Louisiana -- but that on the whole, wealth is a stronger determinant. By the end of the century, a new study from the Union of Concerned Scientists finds that sea level rise could cause half the homes in Hull to face flooding every other week. Modeling Sea Level Rise and Storm Surge Impacts from Climate Change Purpose The purpose of this report is to present key findings of sea level rise (SLR) and storm surge modeling for the City of Cambridge, and to summarize the two technical memoranda provided by the Woods Hole Group and MWH Global that … In Nantucket, a billion dollars worth of homes could be at risk, and across the Massachusetts coast, nearly 14,000 people could be hit by chronic flooding. Over the next 30 years, the study finds 1,100 homes in Revere could face flooding every other week. "So whereas something may not be underwater at every high tide until the end of the century, it could be experiencing this frequent flooding that makes life as we know it challenging decades earlier.”. The CCVA serves as the technical foundation for the CCPR Plan. Five feet will take between 100 and 300 years. Julia Kniseljulia.knisel@mass.gov The following community facilities and infrastructure were mapped: airports, community health centers, commuter rail and subway stations, electrical generation facilities, fire stations, harbormaster's offices, hospitals, landfills, libraries, long-term care residences, police stations, port facilities, prisons, public colleges and universities, public water supply sources, schools (pre-K through high school), town/city halls, wastewater treatment plants, and water supply protection areas. “The current worst-case scenario of sea-level rise from Antarctica is based on the idea that cliffs higher than 90 meters would fail catastrophically,” Brent Minchew, assistant professor in MIT’s Department of Earth, Atmospheric and Planetary Sciences. ON THE RISE Bostonians are getting used to flooding.Morrissey Boulevard (shown), near the campus of University of Massachusetts Boston, gets hit several times a year during high tides. “We knew that the data existed to understand this risk better, and so we wanted to analyze that data so that people are more able to see the threat clearly,” Dahl said. But understanding the threat of the coming decades is potentially even more important than the long term. In 2030, the study points to 3,303 properties as facing chronic flooding, with a combined value of $2 billion. The Curbside Compost Program will expanded to all buildings with 1 to 12 units on April 2. Some 6,500 people live in these “at-risk” homes, according to the study. 2050 Sea Level Rise; 2100 Sea Level Rise; 2050 Sea Level Rise + Major Storm; 2100 Sea Level Rise + Major Storm; TEXT.
