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...

I'm reading the Parable of the Talents at the moment and having lots of 'did I read that in the book or in the news?' moments.

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 ➡️ www.rte.ie/brainstorm/2...

Up on RTÉ 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...

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?

Where are the hurling and football strongholds in Ireland? Analysis of the geographical spread of Gaelic games by @germac.bsky.social Amelia Carroll & Hannah Shen @maynoothuniversity.ie @researchireland.ie www.rte.ie/brainstorm/2... #AllIrelandHurlingFinal #AllIrelandFinal

We've a great line up of MOC talks for this year's IAPSO-IAMAS-IACS conference in Busan, South Korea. I look forward to meeting colleagues and catching up.

This is an update to the work Hannah and Amelia did last summer. We used the winning senior clubs to determine the hurling areas in Munster (circled by blue below). This year we checked that against the clubs of the squads for the final (black dots) and they matched well.

Lovely summer walks up from the train to the office in Maynooth.

Loadsa news up on our webpage. Particular welcome to Emma and Hannah who are with us for the summer and Jittrarast, Lionel, and JP who are doing the MSc projects in the group: icarusoceans.maynoothuniversity.ie?page_id=525

In a busy day for AMOC news, I'm excited to take on the co-chair of the new JPI Climate and JPI Oceans expert-driven assessment of the latest science on the AMOC: www.jpi-oceans.eu/en/shedding-...

Really striking new study from van Westen and Baatsen and a class visualisation tool to go with it. This study looks at a future where the AMOC has collapsed. Temperatures hitting -22ºC in Dublin in the winter is pretty stark. Hearing these numbers can be shocking and worrying. amocscenarios.org

After the Mary Robinson conference in Ballina, it was west to survey an old sea level benchmark for me and Patrick. We got all the weathers but the sun shone for our survey. Croagh Patrick in the background. We are surveying a few points around Ireland to pin down Ireland's sea levels from 1842.

With the turn in the weather, the marine heatwave seems to have peaked. These data are from the M3 data buoy off southwest Ireland. Source: eurosea.marine.ie/his

Surface water temperatures on Lough Feeagh (west coast of Ireland) have been pretty high this year! Daily temperatures in May above the 99th% on most days. 🥵🌡️💦

Study led by Dr Sam Diabaté: In this paper, we were interested in finding out whether the circulation changes recorded at various moorings on and around the Northwest European Shelf were related to the sea-level variability on the shelf. kwnsfk27.r.eu-west-1.awstrack.me/L0/https:%2F...

The marine heatwave off the coast of Ireland is pretty severe at the moment. Temperatures are about 3ºC above normal for this time of the year. Source: www.marine.ie/site-area/da...

We published a signal-to-noise analysis of AMOC observations in GRL. TLDR: Direct observations (RAPID) of the AMOC do show a decline in line with climate model projected weakening (~1 Sv/decade) but the noise is still very large in comparison to the signal. Paper: doi.org/10.1029/2025...

Well after reading this, I'm definitely turning the phone around for selfies. Then I'll be cool (again), right? www.theguardian.com/society/2025...

AMOC in density space, heat and freshwater transports, and 2D velocity fields at 26N have been updated to February 2023. They are freely available on our website at rapid.ac.uk

An important point of conversation. Also featuring ICARUS Maynooth's Samantha Hallam.

I enjoyed talking to @philipb-h.bsky.social for this episode. Nice exploration of dire predictions of AMOC collapse (incl. an interview with Peter and Susanne Ditlevsen) and the revisions to Florida Current estimates (featuring Denis Volkov) that associate with less AMOC decline.

Handy list!

Also should say that that current AMOC trends are unlikely to reach “unfamiliar” (signal‐to‐noise ratio > 2) or “unknown” (signal‐to‐noise ratio > 3) thresholds until the 2040s and 2060s, respectively.

Delighted to announce that @edhawkins.org has been approved for an adjunct Prof position in the ICARUS climate research centre @maynoothuni.bsky.social (I really must set up an ICARUS account here ...) which will formalise and strengthen our existing collaborations. Welcome Ed!

Abstract deadline coming up.. better remember my own!
