Summary:
The United States is expected to experience as much sea level
rise by the year 2050 as it witnessed in the previous hundred
years. That's according to a NOAA-led report updating sea level rise
decision-support information for the U.S. released in partnership
with half a dozen other U.S.federal agencies.

The United States is expected to experience as much sea level rise by
the year 2050 as it witnessed in the previous hundred years. That's
according to a NOAA- led report updating sea level rise decision-support information for the U.S.

released in partnership with half a dozen other federal agencies.


========================================================================== TheSea Level Rise Technical Report provides the most up-to-date sea
level rise projections for all U.S. states and territories by decade
for the next 100 years and beyond, based on a combination of tide gauge
and satellite observations and all the model ensembles from the Sixth Assessment Report of the Intergovernmental Panel on Climate Change
(IPCC). The report projects sea levels along the coastline will rise an additional 10-12 inches by 2050 with specific amounts varying regionally, mainly due to land height changes.

The report updates the federal government's 2017 sea level rise
projections, and provides additional information on tide, wind, and storm-driven extreme water levels affecting current and future coastal
flood risk. A suite of federal tools are using this data, including the
NOAA Sea Level Rise Viewer, which are critical to the Administration's commitment to tackle the climate crisis by making actionable climate
data accessible to those who need it.

"For businesses along the coast, knowing what to expect and how to
plan for the future is critical," said U.S. Secretary of Commerce Gina
M. Raimondo. "These updated projections will help businesses, and the communities they support, understand risks and make smart investments in
the years ahead." "This new data on sea rise is the latest reconfirmation
that our climate crisis -- as the President has said -- is blinking 'code red,'" said Gina McCarthy, National Climate Advisor. "We must redouble
our efforts to cut the greenhouse gases that cause climate change while,
at the same time, help our coastal communities become more resilient
in the face of rising seas." "This is a global wake-up call and gives Americans the information needed to act now to best position ourselves for
the future," said Rick Spinrad, Ph.D., NOAA Administrator. "As we build
a Climate Ready Nation, these updated data can inform coastal communities
and others about current and future vulnerabilities in the face of climate change and help them make smart decisions to keep people and property
safe over the long run." The report also finds that the sea level rise expected by 2050 will create a profound increase in the frequency of
coastal flooding, even in the absence of storms or heavy rainfall.

"By 2050, moderate flooding ⁠ -- which is typically disruptive and damaging by today's weather, sea level and infrastructure standards
⁠ - - is expected to occur more than 10 times as often as
it does today," said Nicole LeBoeuf, NOAA National Ocean Service
Director. "These numbers mean a change from a single event every 2-5 years
to multiple events each year, in some places." "This report supports
previous studies and confirms what we have long known: Sea levels are continuing to rise at an alarming rate, endangering communities around
the world. Science is indisputable and urgent action is required to
mitigate a climate crisis that is well underway," said Bill Nelson,
NASA Administrator. "NASA is steadfast in our commitment to protecting
our home planet by expanding our monitoring capabilities and continuing
to ensure our climate data is not only accessible but understandable."
This multi-agency effort is a product of the Interagency Sea Level Rise
and Coastal Flood Hazard and Tool Task Force, composed of NOAA, NASA,
EPA, USGS, DoD, FEMA and the U.S. Army Corps of Engineers, as well as
several academic institutes. The report leverages methods and insights
from both the United Nations Intergovernmental Panel on Climate Change
(IPCC) 6th Assessment Report and supporting research for the U.S. DoD
Defense Regional Sea Level database.
