No academic certification can match the expertise of children who navigate their community’s streets on their own. Fortunately, certified experts who are willing to listen will find excellent teachers in such children. In this article, Bruce Appleyard shows us how it’s done.

I’m so saddened to hear of the closure of RoadPeace for financial reasons. The charity did so much good — supporting crash victims, standing with bereaved families at their darkest moments, & tirelessly campaigning for safer roads. I hope one day it can be re-established & continue its vital work.

Damrak, Amsterdam in 1987 and today. From multiple lanes for motor traffic there is now only one lane, in one direction, heading out of the city for cars and no car parking. Tram lines and cycleways remain in both directions.

Let alone their future driving permissions… Why is road crime treated differently to other crime? IMO complacency and acceptance of road danger as inevitable have dulled accountability. Strategy isn’t enough — we need a fundamental root & branch cultural reset. www.dailymail.co.uk/news/article...

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%!

Your 'moment of doom' for Jan. 10, 2026 ~ Or even worse than that. "... we can expect more of the same. And by more of the same, I mean more record breaking temperatures, disasters and destruction." www.youtube.com/watch?v=7ACN...

We talked about this in detail on Climate Chat: www.youtube.com/live/BNZ_biC...

The (increased rate of) warming is mainly caused by increasing greenhouse gases and reducing sulphur air pollution from shipping and Chinese coal plants. And cloud feedbacks make it much worse. There is so much more regional warming in the pipeline!

How is 2026 doing so far? Hotter than expected. The global mean surface temperature anomaly for January 1-8, 2026, was 1.60°C above the 1850-1900 IPCC pre-industrial baseline.

Protected cycle tracks alongside main roads, with priority over motor vehicles at junctions, are needed so large groups of young female friends feel safe choosing to ride and don’t have to take risks just to get around. RIding together like this should be normal, not brave.

On the 10th Anniversary of the Paris Agreement, you’re going to hear a lot about the progress we’ve made — people saying we “are” heading to 2.5 degrees heating instead of four. I deeply regret to tell you that this is complacent misinformation. 🧵

False hope fills me with despair. It surprised me how many of those who (should) know better have been celebrating the *false* narrative that the Paris agreement has supposedly limited warming to below 2.6°C this century. Genevieve breaks it down here:

This graph shows the average November volume of Arctic sea-ice. As you can see, November, 2025, set a new record low for sea-ice volume. Volume, thickness and extent are all at record lows right now for the date. The Climate 8-ball is chanting, "Ice free by twenty-fifty."

Cities are better without cars

Breaking News! Code Yikes! The CO2 data for November, 2025, was just released by NOAA, and the 3-year mean rate of atmospheric CO2 growth hit yet another new record high, at 7.93 ppm per 3 years. That dip in the early 1990's is due to Mt. Pinatubo. gml.noaa.gov/ccgg/trends/

We're in a national emergency, but we're not talking or acting as if we are. This dangerous disconnect is why we convened the @nebriefing.bsky.social. Our goal was to reset the national conversation on the climate and nature crises, cutting through the sea of misinformation holding us back. ⬇️

If you haven't already been persuaded to sign the @nebriefing.bsky.social letter on the rapidly escalating climate and nature crises, this summary of the presentations at the National Emergency Briefing event in Westminster, by Dave Borlace, is really worth a watch: youtube.com/watch?v=8sa7...

If you haven't yet watched #DaveBorlace's great #JustHaveaThink show on the UK #NationalEmergencyBriefing #nebriefing, you'll find that it's one of his very best. Have yourself some intriguing few minutes with it, and *please* act on what he says - sign the letter. www.youtube.com/watch?v=8sa7...

I actively avoid calling people on bikes “cyclists.” It fuels an “othering” or “us vs them,” and makes it easier to claim that safe infrastructure is for a small in-group. None of which is helpful. It may take more characters in a post, but I just say people on bikes. Because that’s what they are.
