Why Is the North Atlantic Getting Cold?

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Post-1950s Atlantic 'warming hole' is caused by ocean heat transport change, not surface fluxes” by Rahmstorf et al. (2026). This preprint paper investigates the "cold blob," a unique region in the North Atlantic that has cooled since the 19th century despite... Continue Reading →

Why the South Atlantic is Key to Monitoring the Future Weakening of the AMOC

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Rainfall sustains multiyear La Niña” by Tian et al. (2026). This research investigates how the Atlantic Meridional Overturning Circulation (AMOC) imprints its signal on regional ocean currents, specifically comparing the North and South Atlantic. By analyzing 22,000 years of climate simulations,... Continue Reading →

The Arctic’s New Engine: Why the Great Ocean Conveyor Belt is Defying the Warming Trend

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Atlantification drives recent strengthening of the Arctic overturning circulation” by Årthun et al. (2026). A recent study examines how Atlantification, the northward expansion of warm Atlantic waters, is altering the Arctic overturning circulation. While traditional source regions for dense water in the Nordic Seas have... Continue Reading →
