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.

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.

NEW – Analysis: Clean energy just put China’s CO2 emissions into reverse for first time | @laurimyllyvirta.bsky.social Read here: buff.ly/6eAcjRU
Line chart – China's CO2 emissions are now 1% below their March 2024 peak: China’s emissions from fossil fuels and cement, million tonnes of CO2, rolling 12-month totals. Source: Emissions are estimated from National Bureau of Statistics data on production of different fuels and cement, China Customs data on imports and exports and WIND Information data on changes in inventories, applying emissions factors from China’s latest national greenhouse gas emissions inventory and annual emissions factors per tonne of cement production until 2024. Sector breakdown of coal consumption is estimated using coal consumption data from WIND Information and electricity data from the National Energy Administration.

U-Series sampling day. Taking those lovely polished stalagmites from last week and drilling out top and bottom powder samples so that we can date them and understand their growth history. 100mg should do the trick.
On a white lab bench sits a polished stalagmite slab with ruler, a dremel multitool with drill attachment and various other sampling tools such as a scoop, scalpel and plastic vial.

Continued Atlantic overturning circulation even under climate extremes - Nature
Climate models suggest that the Atlantic Meridional Overturning Circulation is unlikely to collapse this century, owing to stabilization from wind-driven upwelling in the Southern Ocean.

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. 🏭🤞

Now that I've finally made the move, I'm reposting one of my favourite things I made during my PhD: 1 year of output from a regional simulation of the SW Indian Ocean (colours show SST). We often use neat schematic diagrams to represent ocean currents but in reality, it's a rather turbulent mess!
