SLR exposure and AMOC signals
Key Questions
What is the current rate of sea-level rise acceleration?
Global mean sea level is accelerating at 3.94 mm per year based on recent observational data.
What signals indicate changes in the AMOC and Gulf Stream?
Emerging signals point to potential weakening or shifts in the Atlantic Meridional Overturning Circulation.
How is Thwaites Glacier contributing to sea-level rise?
Thwaites Glacier is accelerating its melt, raising concerns about rapid contributions to global sea levels.
Which US areas face high exposure to sea-level rise?
US farmland, the Louisiana coast, and up to 3 meters of inundation in Florida are identified as highly exposed.
What extreme rainfall event affected NYC?
New York City experienced extreme rain at rates up to 150 mm per hour amid rising sea levels.
What does Kopp analysis reveal about Atlantic flooding?
The analysis examines seasonal flood drivers along the Atlantic coast linked to sea-level rise and storms.
How does subsidence affect sea-level rise in coastal cities?
Subsidence more than doubles effective sea-level rise rates in many densely populated coastal zones.
What US cities could be inundated at 3 meters of rise?
Maps show multiple major US cities at risk of going underwater under a 3-meter sea-level rise scenario.
