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 ➡️

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

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?

The butterflies are flying it at the moment. clockwise from top (afaik at least!): red admiral, dragonfly, small tortoiseshell, holly blue (back of wings), grasshopper. From a blackberry picking session on the Old Rail Trail on Saturday.

GAA clubs are found in every corner of Ireland, but you'll find surprising pockets of football clubs in so-called hurling counties and vice-versa

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.

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.

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.

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.

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...

They are mocked by gen Z for everything from their trainer socks to their mom jeans and selfie technique. A maligned millennial asks: how did we get here?
