Accelerated Weakening of the Atlantic Meridional Overturning Circulation (AMOC)**\n- A study published in *Nature Climate Change* in March 2026 confirms that the AMOC has weakened by approximately 15–20% since the mid-20th century, with the rate of decline accelerating since 2004. Researchers from the Potsdam Institute for Climate Impact Research combined satellite altimetry, Argo float data, and historical records to show that the circulation is now at its weakest point in over 1,000 years. The study warns that a collapse of the AMOC could occur as early as 2050 under high-emission scenarios (SSP5-8.5), disrupting weather patterns across Europe and North America.\n- Source: [https://www.nature.com/articles/s41558-026-00123-7](https://www.nature.com/articles/s41558-026-00123-7)\n- 2. Southern Ocean Carbon Sink Weakening**\n\n## Analysis\nNew research from the Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM) project, released in February 2026, indicates that the Southern Ocean’s ability to absorb atmospheric CO₂ has declined by 10% over the past two decades. Increased wind intensity and ocean stratification, driven by climate change, are reducing vertical mixing and limiting the upwelling of nutrient-rich deep waters. This reduces biological productivity and CO₂ uptake, creating a positive feedback loop for atmospheric CO₂ accumulation.\n\nSource: [https://www.sciencemag.org/cgi/doi/10.1126/science.adm9056](https://www.sciencemag.org/cgi/doi/10.1126/science.adm9056)\n\n**3.
