John Gibbons: A big freeze could turn the Irish into climate refugees We should reflect on 'get-tough' proposals on immigration: If the Amoc currents that moderate Irelandโ€™s climate fail, temperatures will plunge, making grass-based agriculture impossible

Interesting piece from @thinkorswim.bsky.social on AMOC collapse and its potential implications for Ireland. Not sure about the headline but big AMOC change would certainly be transformative for Ireland www.irishexaminer.com/opinion/comm...

Is the Atlantic ocean's "wobble" a warning for Ireland? The Atlantic between Ireland and Canada, which gives us our mild climate, is behaving strangely and is the only location on the earth's surface that has cooled

What is going on with the AMOC - the system of ocean currents that gives Ireland its mild and wet climate? With a number of iCRAG colleagues we wrote a short piece for @rtebrainstorm.bsky.social โžก๏ธ

Up on RTร‰ Brainstorm now, together with colleagues Audrey Morley, @tomasbuitendijk.bsky.social, Chris Bean, an article we wrote on the AMOC (gulfstreamsystem, as Joyce would have said) that spans social science, current and past climates and emerging observing: www.rte.ie/brainstorm/2...

Yay! feel very conflicted about what I want from that storm now. Devastation is obviously bad but don't want it to be a woos either.

That would be really interesting. Somebody must have done experiments on Atlantic circulation with the Med open and closed too I guess. It's an important question to know how much extra deep warming in the Atlantic is due to AMOC and has implications for GMST

Definitely thinking of your work @janzika.bsky.social when thinking of ocean vertical heat transport.

I often come back to the Atlantic being warmer than the Pacific at depth. At shallower depths, it seems obvious that the warm water is coming from the Med. But also the vertical heat transport due to overturning processes needs to be remembered. Anyone know of study partitioning those two processes?

Nice to see a bit of life going back in there. It was a shell a long time. I presume it will be a pub again, thinking about it now, it would make an excellent escape room. The heat could be a feature rather than a bug.
