Dynamic Electricity Tariffs are arriving in Ireland (equivalent of Octopus Agile). So I wrote an explainer. Lower bills and lower carbon emissions. A win-win.

RTÉ Brainstorm@rtebrainstorm.bsky.social · 2mo ago

All you need to know about new dynamic electricity tariffs. The introduction of dynamic electricity tariffs next week will result in lower carbon emissions and lower energy prices for consumers, explains @stalagnick.bsky.social @maynoothuniversity.ie @researchireland.ie www.rte.ie/brainstorm/2...

I also spoke to RTE News at One yesterday on what an Early Warning Flood System for Ireland would look like. This morning, they've also turned that into a Brainstorm article!

Wrote a thing for RTE Brainstorm! When Does Spring Begin? February or March? In the article I touch on how Ireland's unique geography and climate result in a battle of light versus warmth in shaping our perceptions and definitions of the beginning of Spring.

RTÉ Brainstorm@rtebrainstorm.bsky.social · 6mo ago

February or March: when does spring really begin? The Celtic calendar says spring starts on February 1st, but climatologists are adamant it's March so @stalagnick.bsky.social @maynoothuniversity.ie @researchireland.ie finds out who's right www.rte.ie/brainstorm/2...

Coulombe et al report on a buried glacial ice deposit on Bylot Island in northern Canada. This ice, based on paleomagnetism measurements is from the Early Pleistocene. Since it overlies a forest deposit, they hypothesize it is 2.4-2.8 million years old. Remarkably old! doi.org/10.1130/G524...

Amazing new record. Ireland tops 100% renewable generation for the first time ever. Thanks interconnectors. Thanterconnectors.

Green Collective@greencollective.io · last yr.

🚨 Domestic renewable generation exceeded Irish electricity demand between about 3am and 6am this morning with wind output alone peaking at 103.3% of demand just after 5am, setting a new record on the Irish grid. We'll have more analysis later today! 🏅

The most impressive part of the improvement in weather forecasting was in 1991 when scientists managed to invent a time machine to go back and improve the five day forecast. Either that or someone forgot to sort the columns by date before plotting.

Can we use speleothem growth phases to trace the growth and decay of past ice-sheets? Our compilation of 1020 U-series dates from the UK and Ireland says Yes! Read all about it in our 📣New Paper📣 led by Sina Panitz, feat @speleoseb.bsky.social, myself and others, out now in Climate of the Past.

Kicking off the new year with a 📣New Paper📣 in Paleoceanography and Palecolimatology, led by Alexander James at USC, with Jun Hu, Julien-Emile Geay and others. In it we explore whether we can find regime changes in the Holocene Asian Summer Monsoons. We can for 8.2, but 4.2 falls short.

Absolutely delighted for Ros! Prof. Rickaby was my MESci thesis supervisor, and I could not have wished for a better start of my research career with Ros as a supervisor and with all those in the group she led. (Even if I did jump ship (haha) to terrestrial paleoclimate)

Santa won't be leaving coals for anyone this year... It's a week now since Moneypoint was in operation. With the end of the year targetted for shutdown, we suspect the era of coal generation in Ireland quietly ended last week, just a few months after the UK's last coal plant shuttered. 🏭🤞

Latest sunset in Ireland was today. What are you going to do with all that extra light tomorrow evening?

Zero Stretch!!!!! Now, *because* it's after sunset now, there won't be a stretch until tomorrow, so we don't declare the Grand Auld Sthretch in the Evenings until after tomorrow's sunset!
