Weakening of the Atlantic Meridional Overturning Circulation (AMOC)**\n- Multiple studies published in early 2026 confirm that the AMOC is at its weakest state in over a millennium. A study in *Nature Climate Change* (January 2026) analyzed updated ocean sensor data from the RAPID array and satellite altimetry, showing a 15–20% decline in circulation strength since the mid-20th century. Researchers from the Potsdam Institute for Climate Impact Research used machine learning to analyze paleoclimate proxies and modern observations, suggesting the AMOC could reach a tipping point by 2050 under high-emission scenarios. This slowdown is linked to increased freshwater input from Greenland’s melting ice and altered wind patterns.\n- Source: [Nature Climate Change, DOI:10.1038/s41558-026-00012-8](https://www.nature.com/articles/s41558-026-00012-8)\n- 2. Southern Ocean Upwelling Intensification**\n\n## Analysis\nA February 2026 study in *Science* using data from over 1,200 Argo floats and biogeochemical sensors revealed that wind-driven upwelling in the Southern Ocean has intensified by approximately 10% since 2000. This brings deeper, carbon-rich, and more acidic waters closer to the surface, reducing the ocean’s capacity to absorb atmospheric CO₂. The study, led by researchers at the University of Tasmania, also found that enhanced upwelling is accelerating surface acidification in key regions near Antarctica.\n\nSource: [Science, DOI:10.1126/science.adl4882](https://www.science.org/doi/10.1126/science.adl4882)\n\n**3.
