The Atlantic Meridional Overturning Circulation moves warm water north and cold water south, regulating climate across the Northern Hemisphere. Melting ice is injecting freshwater that disrupts this cycle.
Boston, New York, and Miami are experiencing accelerated sea level rise directly tied to AMOC slowdown. A weaker current allows water to pile up along the East Coast shoreline.
Counterintuitively, AMOC collapse could bring severe winters to the northeastern US while overall global warming continues. This paradox would devastate agriculture and energy systems.
The Gulf Stream (part of AMOC) drives the nutrient upwelling that sustains New England's fishing economy. Disruption would collapse fish populations that fishing communities depend on.
A 2023 Nature Communications study suggests AMOC could cross a tipping point decades earlier than the IPCC projected. Once past the threshold, the collapse could be irreversible within a human lifespan.
Limiting global warming to 1.5°C is the only way to preserve AMOC and the stable climate it provides. This isn't distant science — it affects every American coast and farm. Read Deep Dive →
Data from federal agencies shows this issue directly affects millions of Americans. Understanding the scope is the first step toward meaningful action and lasting solutions.
Across the United States, communities are experiencing the real-world consequences. Local economies, public health, and ecosystems are all interconnected—solutions must address all three.
Leading scientists from NOAA, NASA, EPA, and universities nationwide are documenting alarming trends. The evidence is clear: urgent action is needed to protect America's future.
