#GAIS vinner igen 1-0 Salter.
Ongoing experimental work at the UCD Lab is advancing burning studies and ROS measurements of aerosols generated from solid fuels, contributing key findings to the #SolidAir and #EpicAir research projects. @ucc.ie @uniofgalway.bsky.social @researchireland.ie @ucddublin.bsky.social

Meanwhile, no meaningful precipitation in Finland in this year so far. Snow depths are exceptionally low in central Finland despite the cold January.

Incredibly stuck pattern!
Most people are worried about climate change - but most don't hear or talk about regularly.

That's why I started my free newsletter Talking Climate. Every week I share good news, not so good news, and what people can do.

Malmö det goda exemplet.

Varför är det så få som lyfter att Malmö kommit tillrätta med skjutningar (minskat med 70% sen 2018) utan alla verktyg på rättsområdet som regeringen tar fram nu.

Snarare har polisiära- och avhopparåtgärder hjälpt.

I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good.

Roligt att Trump sa att om det inte vore för USA skulle alla prata tyska.

I saw an interview checking in with MAGA & EVERY one of them assessed how well or poorly Trump's presidency is by how HE affects THEM.

They all used "Me" statements.

There really are 2 kinds of people in this world: those who vote for society at large... & those who think "me me me" in their head.

The 1991-2020 climate doesn't exist anymore 😟

In a sane world, this would be front page news everywhere.
But it will hardly be covered anywhere.

The North Pacific Ocean surface warmed over twice as much over the past 15 years than it did over the preceding 156 years.

That's an increase in warming rate of >2000%!
Good morning and happy New Year's Eve to everyone. Time zones are so weird. Australia is already in 2026. Europe is still in 2025. And the United States is in 1933.
New paper! How are emissions scenarios 📉 from the IPCC (and other sources) actually used by decision-makers? We asked them, and the results are out just in time for the holidays 🧑‍🎄🤶🧑‍🎄 (with @idasogn.bsky.social & @climansen.bsky.social)

Human-caused climate warming is supported by atmospheric chemistry, energy-balance models, and observational datasets.

EPA: ‘Let’s remove it from the website’.

Apparently peer-review is now a Cult™ doctrine.

New evidence suggests weather persistence is increasing in the northern mid– and high latitudes due to climate change.

So far, I’ve been skeptical as the signal seems small compared to natural variability, but maybe it’s time to update my thinking.
