“When mayors in other cities ask me how #Copenhagen afforded to invest in its cycling networks, I ask them how on earth they have been able to afford highway projects. We invested in bike lanes because that was the cheapest option.” What the world can learn from Copenhagen’s cycling revolution.

The Intergovernmental Panel on Climate Change faces perhaps the most serious crisis in its nearly 40-year history — but it is too precious to lose go.nature.com/4yRa7KZ

High pressure looks to set up by the end of this week - it's within the top 97.5-99%iles of climatology; how sunny it'll be depends on the orientation of the high, which is still being played with. Near record high to near record low to near record high, the weather for you. 😁

wanted to write about this, but found it simpler to draw it instead

📣 The review of the First Order Draft of the Working Group II contribution to IPCC’s Seventh Assessment Report on impacts, adaptation and vulnerability has started. Interested experts can register until 20 Nov 2026: https://bit.ly/4y1LI58 The review ends on 4 December.

Greenhouse gas levels hit new record highs, locking in more long-term temperature increase. The intensifying El Niño may lead to a further surge. New WMO Greenhouse Gas Bulletin provides authoritative scientific information on the state of our climate. 👉 https://bit.ly/4iIqwMR

The latest climate pledges put forth by nations will cut global greenhouse gas emissions just 6% by 2035, a UN report has said, weeks before COP31 talks in Turkey.

San Diego and LA both have more than 100 yr of tidal records, and today both sites saw their highest tide levels on record with no storm or high winds (h/t to @drjeffmasters.bsky.social and @edwardsanthonyb.bsky.social for great coverage of this) balancedweather.substack.com/p/san-diego-...

Some unhinged comments and quote posts on this. Machine learning with artificial neural networks has transformed the environmental sciences, and rightly deserved the 2024 Nobel Prize in Physics. This isn’t using a chatbot to predict hurricanes.

September data for HadCRUT global temperature now available. 2026 (based on Jan-Sep) best estimate is second warmest in this record, but uncertainties overlap with all of 2023-2025 to some extent.

⚒️ 🧪 Earthquakes have been swarming offshore Vanuatu. What’s going on in this corner of the world? More fascinating than this latest swarm is the history of islands perched above the subduction zone, carried up and down by movement of the slab below. earthquakeinsights.substack.com/p/earthquake...

It's really important to pay attention to the fact that Lula beat the fascist candidate not by compromising and trying to meet fascist voters in the middle, but by sticking to his guns, promising prosecutions for election interference, and mobilising his own voters to turn out in greater numbers.

I assume everyone who wrote about the hospital bike shed in their columns and talked about the hospital bike shed on their radio shows and tweeted about the hospital bike shed on their Nazi owned micro blogging app are very excited to discuss this

A compelling talk by Raewyn Peart of Environmental Defence society about the NZ post code lottery approach to climate adaptation and protection that we currently have as the result of a lack of planning & real budgeting by successive NZ governments -thanks Australia Climate Adaptation 2026 fir this

Ohio’s biggest newspaper broke its own rules to endorse Amy Acton, calling Ramaswamy’s vile attack ad disqualifying. “Using childhood sexual abuse as a weapon against the person who endured it crosses a line Ohioans should defend, whatever their party.” thedailybeast.com/trumps-maga-...

Saturday El Niño update - Sea surface temperatures are still warming across Niño region 3.4 over the last week. Note that I finally had to readjust the scale on the map view, so it's not quite comparable to prior updates. 🌊 Data from @noaa.gov OISSTv2.1: www.ncei.noaa.gov/products/opt...

After weeks of periodic heavy rains, the San Juan River system in CO and NM is in the middle of a truly historic flood that appears to be causing catastrophic impacts to the rural Four Corners region — the word needs to get out on how bad things are: balancedweather.substack.com/p/record-cat...

"Overall, we are seeing some very odd deal talks that are supposedly a part of ending the war in Ukraine. But in fact, evidence shows these deals are structured (in the most recent case secretly until now) to financially benefit Russia or business partners of the Trump and Witkoff families."

Great discussion with Olya Irzak on just how high the methane leakage may be from off-grid data centers powered by low-efficiency reciprocating gas engines. Another reason to ensure that if data centers are built, they are on the grid!

Ending Ireland's dependence on gas and oil is proving painfully slow www.irishtimes.com/environment/...

Is there anything that you would recommend normal people do at this moment to improve their internet hygiene? Surý: I would recommend that they rely on experts. That’s what we all do in a crisis: We talk to experts + trust them. Rely on that people who take care of this stuff know what they're doing

#StormBoelo #stormsurge for western Scotland on Sat 24th Oct is looking pretty high. Millport (mouth of the Clyde) is forecast about 1.5m on top of a fairly high tide. This is a tide + surge estimate only, does not include waves or rivers. ntslf.org/storm-surges...

Update...it's not just Canada 🤦‍♂️ As a cost-cutting measure, NWS has removed ALL international observations (outside of US buoys) from its site. A shame that such a simple and helpful tool had to be removed due to the Trump administration's anti-science budget cuts.

50,391 heat-related deaths across 854 European cities in one summer. Of these, 32,619 were attributed to the extra heat caused by burning coal, oil and gas. Now tell me climate action isn’t essential... www.independent.co.uk/news/arctic-...

You hear all the time about how our society is too intimately tied to fossil fuels to easily do away with them. What you don't hear about so often is how the fossil-fuel industry deliberately planted that idea in our heads decades ago. Great piece from @grist.org grist.org/culture/hidd...
