I’ve had a lot of responses to this piece, so I want to clarify a few things. Writing and posting views like this isn’t easy. It often leads to pushback, even when the criticism isn’t aimed at individuals.

hi, medical toxicologist that knows a lot about Tylenol here👋 Claiming that tylenol use in pregnancy causes autism is fearmongering here's what you need to know 🧵

The 27 year old woman who was killed in Cork yesterday was cycling on a 50kph street in an urban area. The default 30kph limit promised by the govt may not have saved her life but it will save lives in the future. We can't allow them to renege on that promise. www.irishexaminer.com/news/munster...

Irish media reporting on road collisions too often dehumanises victims and hides driver responsibility. Cyclists and pedestrians are people first — the language we use matters. Read our full statement below.

The meeting was a disaster for everyone except two people. Trump got his photo op and his ego boost. Putin got his photo op, whitewashing of war crimes and no sanctions. No one in Ukraine, Europe or the United States benefited in any way.

Look at this cool map by @briggsrogers.bsky.social visualising the number of reports to collisiontracker.ie per 30m/sq, including accidents, near misses and hazards.

There’s a lot to unpack from the @irishtimes.com this morning besides the ongoing anti-cycling nonsense. This letter makes no sense. Yet another excuse-laden rant defending business as usual. Ireland deserves to pay its climate fines. We’ve made our choices. "Whataboutism" won’t cut emissions.

🕊️ Every road death is preventable, let’s stop acting like it's just a part of life. It is unacceptable that the convenience of people using motor vehicles outweighs the safety of people walking, wheeling and cycling in our densely crowded city. 🚶‍♀️ 👩‍🦽 🚲 🚗 💨

Ireland is an ecological disaster zone. And the largest land-owner in the country is a part of the problem. www.youtube.com/watch?v=vCXP...

If we are serious about road safety, if we are serious about climate action and a liveable future, it is certainly time to consider banning SUVs. A powerful letter by our own @olaln.bsky.social in this morning’s @irishtimes.com.

If we are serious about road safety, if we are serious about climate action and a liveable future, then we should ban SUVs. My letter in today's @irishtimes.com.

More flights, more emissions. My letter to the editor in today’s Irish Times. The media continues to offer free PR to high-emission industries such as aviation. This has to stop if we are to get serious about climate action. #BanFossilAds

Brilliant letter by our very own Dr Callum Swift in the Irish Times this morning! #ActiveTransport

Big Box retail is car-centric sprawl that wipes out small business, hollows out Main Streets, and leaves cities with giant dead shells. Every town ends up looking like nowhere. A new Not Just Bikes video. 👇

“We need carmakers to prioritise normal-sized cars that can be parked more easily and are less dangerous to people walking around. It’s only fair if you want to buy a massive SUV that you should expect to pay more for the space it takes up.” www.theguardian.com/environment/...

Dr Caoimhe Clarke recently embarked on a 3-day train and cycle journey through the eastern Netherlands, and what a revelation it was. Read the full piece using the link! #ActiveTravel #ActiveTransport #SustainableTravel

I went car-free living in Waterford. Here’s how it’s going. Possibly the best investment we can make for a sustainable and healthy future is one that normalises cycling www.irishtimes.com/opinion/2025...

"Wales’s 20mph speed limit has cut road deaths. Why is there still even a debate?" - really nice to see our motonormativity research being used to explain this. Cheers, @peterwalker99.bsky.social www.theguardian.com/world/2025/m...

More talk, no cattle here since he’s not going anytime soon: There has never been a manned Starship flight ever and there will not be until it is safe (last two launches went boom and most of others, eight in total, except a shaky 4th and an excellent 5th, have had an explosive result).

My letter in the @irishtimes.com this morning. The media must do a much better job when it comes to reporting on road deaths.

The Irish government is reportedly preparing to buy US LNG from fracked gas, by allowing the construction of a commercial import terminal, in exchange for economic concessions from Trump. We need to cut dependence on fossil fuels as quickly as possible - not lock it in for decades.

Justin Timberlake, welcome to the war on cars!

Enjoyed taking part in #ShiftNow Sustainable Healthcare & #Climate Solutions roadshow panel discussion in the Clarence Hotel this evening, with the good folks from @irishdocsenv.bsky.social, among others.

Thanks to all the absolute soundies who attended the #ShiftNow event tonight in The Clarence Hotel. Do one high impact thing. Ask your pension provider to invest in more sustainable pension funds (often better performing) and away from fossil fuels.

Our very own @olaln.bsky.social is featured on this list! 🌍 "The climate crisis is the defining health emergency of our time. To put it simply: No nature, no health. 🌿💚 #PlanetaryHealth #ClimateCrisis #ClimateHealth #SustainableHealthcare

If you are a pedestrian or a cyclist, this is not shocking at all. AT ALL.

Any measures aimed at limiting the perceived rights of motorists to drive as fast as they want, where they want and when they want, results in the most hysterical response. I recently heard a local resident describe cycle lanes as turning his town into Gaza

An amazing and important initiative highlighting areas where risk of collision needs to be addressed

Now I berate myself for not paying out of pocket. I hadn’t realized it was an option, but of course it was – $1,300 would have been more than worth it. I can’t help but think that United Healthcare lost their gamble. This hospitalization will cost them far more than the medication would have.

Sally Rooney: When are we going to have the courage to stop the climate crisis? www.irishtimes.com/life-style/p...

A typical European car spends 1/5th of its driving time looking for parking. Its 5 seats only move 1.5 people, and it’s been getting bigger & heavier. 86% of its fuel never reaches the wheels, and most of the energy that does is needed to move the car itself, not the people in it. Sound efficient?

It’s done - the hellsite is now a thing of my past. Hello Bluesky! I’m here to tell you all how amazing cargo bikes are!

🚀 Today we launched our manifesto for the general election #GE24. 🌏 Now is the time to change course - away from fossil fuels and toward a healthier future. We must act now! There is no time to lose! 🔗 Find the manifesto here: ide.ie/political-ma...

1. Who really won the US election? The fossil fuel companies and other polluting industries. We scarcely heard about them during the election campaign, which is just how they like it. Almost everything we *did* hear about was a distraction from the real agenda. 🧵
