Q2. “Global ocean current systems are critical regulators of regional climate stability”. Discuss how the collapse of the Atlantic Meridional Overturning Circulation (AMOC) could alter global hydrological cycles. Evaluate its potential to trigger abrupt climate change events. (15 M)
Difficulty Level: Medium
Reference: DTE
Why the question Recent Utrecht University 2025 modelling study on AMOC collapse and its impact on Europe’s winters and global hydrological cycles has revived debates on ocean currents as critical climate regulators. Key Demand of the question The question asks to examine the role of global ocean currents in climate stability, analyse the effects of AMOC collapse on hydrological cycles, and evaluate its potential to trigger abrupt climate change events. Structure of the Answer: Introduction Briefly introduce the role of ocean currents in maintaining Earth’s climate equilibrium. Body Global ocean current systems as climate regulators: Discuss how currents modulate temperature, precipitation, and circulation. Impact of AMOC collapse on hydrological cycles: Analyse changes in monsoon patterns, rainfall shifts, Arctic melt feedbacks. Potential for abrupt climate change events: Examine risks like cold waves in Europe, sea level rise, ecosystem collapse, and tipping points. Conclusion Highlight the need for enhanced climate modelling and global cooperation to prevent or adapt to AMOC disruptions.
