Accurate expert voices in the mainstream media are the most effective counter to AMOC sensationalism around "Day After Tomorrow" collapse scenarios. Here's part 2 with Chris Smith from The Naked Scientists. Check our recent spotlight article on AMOC discourse: epoc-eu.org/amoc-collaps... [2/2]

EPOC researcher David Thornalley (@ucl.ac.uk) appeared on @bbc5live.bsky.social with Naga Munchetty and Chris Smith to explain: 🗺️why AMOC matters 🥶what AMOC weakening actually means for the UK 🌧️why the consequences extend well beyond Europe [1/2]

May 2023 bloom occurred under >80% sea ice, with minimal light availability, challenging conventional bloom initiation thresholds for Atlantic Water regions. SWIPS (Subsea Winched Profiling System) collected profiles through polar night addressing sampling gap in Arctic oceanography. [2/3]

Warming rate of 0.20°C/decade exceeds global ocean rates. Data reveal multi-annual warm / cold anomalies with 2-year typical duration, but most recent cold period lasted 5+ years, unprecedented in this record. Suggests shifting baseline conditions in Atlantic Water source regions. [2/3]

Atlantic Water temperature variability in the WSC branches. Timeseries of annually averaged Atlantic Water (AW) temperatures for the WSC core , the offshore branch, and the combined WSC, with the standard deviation shown as whiskers. Long-term linear trends for each branch are plotted as dotted lines and listed in the legend. Shading marks warm (red) and cold (blue) AW temperature anomalies. Vertical lines indicate the start of each decade. (For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article.)

Public engagement with AMOC science is EXACTLY what climate discourse needs. 🗣️🌍🌡️ Recent weeks saw collapse scenarios reach millions through @nebriefing.bsky.social & Ben Miles' content predicting -20°C in London & complete agricultural collapse. 🥶 But does the framing reflect the evidence? [1/7]

DYK the ocean has a "memory"? The ocean moves slowly, holds heat for decades, staying insulated from surface processes. 🌊 A signal formed today persists for years as it travels through subsurface currents. That memory makes long-range prediction possible... [1/3]

This provides new constraints for evaluating Atlantic Meridional Overturning Circulation (#AMOC) behaviour across different climate states. This also brings palaeo-reconstructions into closer agreement with climate models; useful for testing model performance under more extreme boundary conditions.

📣 New EPOC results reveal that during the last ice age the Atlantic’s powerful current system remained active and continued to transport warm, salty water from the tropics to the North Atlantic despite extensive ice cover across much of the Northern Hemisphere.
