The AMOC is under threat from human-caused climate change, as warming seas, melting ice and increased rainfall upset the temperature and salt balance of the North Atlantic.

AMOC: Is global warming tipping key Atlantic ocean currents towards ‘collapse’?
Abatify Summary
Nature & Climate Perspective
**A potential AMOC collapse represents a catastrophic climate tipping point that would irreversibly degrade global LULUCF performance and undermine the permanence of blue carbon sequestration projects. **
- Disruption of the AMOC would lead to a rapid shift in precipitation and temperature regimes, potentially converting established terrestrial carbon sinks into net emitters through mass die-backs.
- The weakening of vertical ocean mixing reduces the efficiency of the biological pump, directly impacting the integrity of blue carbon credits by altering the rate of deep-ocean carbon burial.
- Long-term environmental stability, a prerequisite for the 40-year permanence required under many ICVCM-aligned methodologies, is threatened by the non-linear feedback loops triggered by freshwater influx from Greenland's ice melt.
Market & Policy Outlook
**The systemic risk of ocean current destabilization threatens the foundational pricing models of the voluntary carbon market and necessitates a re-evaluation of SBTi-aligned transition risks. **
- Policy and regulatory frameworks may undergo emergency pivots, potentially triggering Article 6.4 safeguard mechanisms as regional agricultural productivity and LULUCF baselines shift dramatically.
- Financial liquidity for nature-based solutions (NBS) faces 'stranded asset' risk if regional climate shifts render existing reforestation and conservation projects ecologically unviable.
- Corporate compliance strategies linked to SBTi or Scope 3 targets would require radical adjustment as supply chain volatility increases, likely driving a flight to quality for highly technical carbon removals over traditional offsets.
