We don’t know how close we are to triggering an Atlantic Ocean circulation #AMOC breakdown - but now we know a lot more about what it would mean for extreme temperatures in Europe. Good @carbonbrief.org piece on a new study just out by the Dutch colleagues! 🌊

Ocean current ‘collapse’ could trigger ‘profound cooling’ in northern Europe – even with global warming - Carbon Brief
A “collapse” of key Atlantic ocean currents would cause winter temperatures to plunge across northern Europe, overriding the warming driven by human activity.

Good opening words from Vidar Helgesen at the Ocean Decade Forum in Nice - “at a bad time for multilateralism we are still making good progress we the ocean” - he also said however that much needs to be done to deliver SDG14 by 2030.

Walking in the Elan Valley earlier this week - water levels looking very low in the reservoirs, a mix of lack of rainfall, and planned engineering work.
The UK really does need to build more water storage infrastructure as rainfall patterns change and the whole place warms up.
