I have to admit, while I find it cringey when people post 'facts' on the internet that can be easily be debunked with minimal searching, posting something statistical when the bad maths is staring you in the face is next-level.

Countries that weaken or stop their #netzero and #climate actions may be consigning their populations to decades of preventable #airpollution illness. My latest for @theguardian.com on research led by Imperial College London. www.theguardian.com/environment/...

Melting glaciers caused almost 2cm of sea level rise this century alone, study reveals - "Every centimetre of sea level rise exposes another 2 million people to annual flooding somewhere on our planet.” #climatecrisis www.theguardian.com/environment/...

Eye-watering impact of traffic-pollutant nitrogen dioxide (NO2) on neonatal ICU admissions bit.ly/4bdaa9z Abstract from the Nature study: "Despite rel low-moderate US exposure levels, traffic-related pollutants...appear to increase overall adverse health risks for newborns" @johnwenger9.bsky.social

Final report on the emissions from domestic stoves just dropped. This was a Ricardo-led project I was involved in looking at an extensive range of different fuels and stoves used in the UK, looking to update emissions factors used in the inventory. uk-air.defra.gov.uk/library/repo...

NEE is the next big thing we need to focus on in cars - while EVs and hybrids give off less brake dust than conventional ICE cars (because of regen), they don't eliminate it entirely, so could formulation to make it less toxic be an answer? theconversation.com/car-brake-du...

Anyone remember the lead-crime hypothesis, where a peak in crime in the 80s/early 90s was partly attributed to Gen Xers being exposed to lead, e.g. in exhaust fumes? NGL, the fact that this age group (which includes myself) is now in charge bothers me. www.sciencedirect.com/science/arti...

The full stop of the increasing winter sea-ice extent in the Arctic has now lasted for two weeks... 🌊⚒️🧪🥼❄️

Air pollution causing 1,100 cases a year of main form of lung cancer in UK Health experts and cancer charities say findings should serve as wake-up call to ministers #AirPollution #Health www.theguardian.com/society/2025...

This isn't good.

The whole business about SMRs needs talking about sensibly and hailing from Cumbria, I consider myself very familiar with how uninformed the debate regarding nuclear can get. People need to get their facts straight regardless of their position.

Probabilistic predictions are always hard to present. The Guardian says "...danger is likely to fall with more data." How likely, one might ask? Well, there's a 2.3% chance it ultimately won't, so that statement is basically redundant (if reassuring). www.theguardian.com/science/2025...

👏 “After one year of the zone, nitrogen dioxide from traffic was lower, GP visits for respiratory illnesses were down by 25% and those for heart problems decreased by 24%”

happy first birthday to Bluesky, and what a year it's been! with every day, the need for an open network that puts people first becomes increasingly clear. we're glad to be building this with you. after all, the heart of a social network is the people.

Every year during #LGBTHistoryMonth we reaffirm our belief that LGBT+ individuals should feel safe, seen & thrive in their place of work & study. #LGBT+ inclusivity is key to ensuring science continues to take inspiration from diversity of thought, experience & perspective rsc.li/3Q6aMo4 #ChemSky

This needs repeating as often as possible. I remember very clearly the climate deniers pushing the narrative of a 'pause' very hard, but they have been proved dead wrong. So why should anyone pay any attention to them now?

We are alarmed by the Administration’s actions to freeze science funding and eliminate DEI efforts and climate change initiatives, which go against AGU’s mission and harms our members. We must unite to address these changes, beginning by hearing from you. Read more: https://buff.ly/4hm8r4e

Diversity is not a dirty word. Science (and academia in general) benefits from it and it therefore should be encouraged. Good to see this from the AAAR.

We are getting our FAAM Airborne Laboratory ready for a summer of science projects - from measuring sulphur emissions in the Atlantic, to tracking the passage of air in the Alps. This involves reconfiguring our scientific instruments on the aircraft. Read the article: ncas.ac.uk/preparing-ou...

Here's a thought. At uni, we're having to think hard about how we make our assessments more AI-proof, but assuming the tools just keep getting better, should we teach and test how to do literature surveys in the future? That skill could very easily go the way of slide rules and sling hygrometers.

This is interesting. Aviation safety uses the 'Swiss Cheese' model, where multiple things have to go wrong for something bad to happen and near misses should tell you the holes in the proverbial cheese slices need to be smaller. www.bbc.com/news/article...

This is what the government did with 120K+ Japanese Americans in 1942. I know. I was there in those camps.

Let’s go down memory lane to visit a few milestones that our atmospheric research aircraft has experienced! From studying volcanic ash clouds to flying in sync with satellites to research storms - where will we go next? ✈️

Milestone reached! Our atmospheric aircraft at the FAAM Airborne Laboratory has logged 10,000 flight hours since 1981, with 6,849 hours dedicated to ground-breaking science. Read the story: ncas.ac.uk/10000-hours-...

🌍 UK Weather & Climate 🌍 The weather and climate of the UK are shaped by the large-scale circulation of the atmosphere and ocean in the North Atlantic. Many factors influence these patterns, but rapid or disruptive changes are a major concern. #ClimateScience

I somehow missed this one. GM's alternative plan to a clean air zone has been approved by DEFRA. It'll be interesting to see how this plays out. www.manchestereveningnews.co.uk/news/greater...

With business-as-usual, global #yields may decline from 2015 to 2080 by -22% for #maize, -15% for #soybeans, -14% for #wheat & -9% for #rice, suggesting benefits from #emissions mitigation. Uncertainty can be so high, investing in #climatechange adaptation is only cautious: doi.org/10.1038/s415...

On Sunday 26 January it was International Day of Clean Energy. We’ve done a recap of our renewable efforts over the last 18 months, including: 🔋 Solar-powered labs 🌱 Biofuel for weather radar ❄️ Solar + wind at Greenland camp 🛢️ Sustainable fuel for our research flights ncas.ac.uk/ncass-renewa...

Here's my thoughts on the latest round of discussion about the slowing of the Atlantic overturning circulation. It's a bit nerdy - but the short summary is: in my view the balance of evidence strongly suggests that the #AMOC has slowed since the late 19th C. 🌊 www.realclimate.org/index.php/ar...

I don't know if the ASCENT network has a presence on BlueSky yet, but I got this from Twitter. They're making their data available from the US supersites in light of the LA fires. ascent.research.gatech.edu/database

Random shower thought for the day: For hundreds of years (I'm going to say since the Renaissance), rich white guys have generally been the self-appointed curators of academic knowledge, and that's a problem. By corollary, rich white guys saying it isn't a problem doesn't make it go away.

In case anyone hasn't had enough depressing news lately. The article is paywalled, but the title pretty much says it all; this is an outcome that many like to think is unthinkable. www.researchprofessionalnews.com/rr-news-uk-r...

Wouldn't say I have fond memories of these buses from my student days, outside of the low prices. They were somewhat notorious (especially the original 6-wheelers) for belching out black exhaust smoke. Glad the buses have cleaned up since! www.bbc.co.uk/news/article...

Well done humanity. For it is us who have caused this rapid warming of the planet, and the devastating consequences for people and ecosystems that are so visible today and every day. theconversation.com/my-new-dark-...

2024 has recorded the highest temperature in any year since 1850 🌡🌍 This is the 11th year in succession that has equalled or exceeded 1.0°C above the pre-industrial average period A number of centres released their estimates today: www.metoffice.gov.uk/about-us/new...

The global average temperature for 2024 was 1.53±0.08°C according to data collated by the Met Office, the University of East Anglia and the National Centre for Atmospheric Science. www.metoffice.gov.uk/about-us/new...

This is an interesting read and there is a link to the research paper in the article. I was particularly interested in the bit about indoor air quality and what they focus on is the benefit from moving away from gas cooking.

Very timely paper regarding the current situation in LA, the concept of climate change causing increased 'whiplash' events, transitioning from wet to dry or back again. In this instance, growing and then drying out of fire-prone plants. www.nature.com/articles/s43...

Random science thought: Have any flat earthers ever attempted to explain sundials? I don't see how one could possibly reconcile the apparent angular motion of the sun with the fact it's midday at least somewhere on Earth at any time. But maybe I'm just shilling for 'big sundial' or something.
