Helen Findlay Urges Action on Weakening AMOC as 2020 Ocean Risk Zones Expanded

2 articles · Updated · Mongabay.com · Jun 2

Helen Findlay argues new AMOC research should be treated as a warning that impacts could be more severe than projected, and that uncertainty over timing is a reason to act now rather than wait.
The Atlantic current system helps regulate climate and marine ecosystems by moving heat, oxygen, carbon and nutrients; a weaker AMOC could disrupt plankton, fish stocks, seabirds and marine mammals.
Findlay says scientific caution is often misread as doubt even though models broadly agree on risk, with some projecting gradual weakening this century and others allowing for earlier abrupt shifts.
Her case draws on 2025 ocean-acidification research showing that by 2020 large areas of surface and subsurface waters had already entered a "zone of risk" for ecosystem change.
The op-ed calls for more real-time ocean monitoring, sustained science funding and faster greenhouse-gas cuts, arguing AMOC weakening would compound warming, acidification, deoxygenation and biodiversity loss already underway.

AMOC on the Brink: The Accelerating Decline of the Atlantic’s Climate Engine and the Global Collapse Risk

Overview

Scientists warn that the Atlantic Meridional Overturning Circulation (AMOC), a vast system of ocean currents crucial for global climate regulation, is weakening rapidly. The AMOC delivers warmth to northern Europe and shapes weather patterns worldwide. Recent observations show its strength has dropped by 10–20 percent since the mid-2000s, with hundreds of millions of gallons of water per second no longer flowing northward. This decline raises fears that the AMOC is nearing a tipping point, and its potential collapse could dramatically reshape the global climate and human societies.
