There are far more divergent perspectives about the IPCC timeline issue than what has been reported in climate media. Here is the report by Third World Network which is one of only two organisations, other being Earth Negotiations Bulletin, that has access to negotiation rooms twn.my/title2/clima...

But this "overshoot" discussion is so esoteric. It bizarrely avoids the elephant in the room. Emissions need to drop radically in the short term. Overshoot, IMO, distracts from that, and focuses people on unnecessary details 100 years in the future.

Anthropic's IPO prospectus has some things to say about climate risks... "the physical effects of climate change may increase our operating costs over time, as higher average temps can increase the power consumption and water usage required to cool equipment at the facilities on which we depend"

"Das Heizen der privaten Haushalte als staatliches Regulierungsobjekt" ... "Die Erfindung des »Energiesparens ohne Komfortverlust«" 🔥 Open Access.

NDC 3.0 Papua New Guinea 🇵🇬 "PNG will pursue a pathway toward net zero by 2030 and net-negative emissions by 2035 through strengthened action across energy, transport and land-use sectors." openclimatedata.net/ndcs/papua-n...

Exceeding 1.5°C of warming is now unavoidable. But how much further temperatures rise depends on how quickly we cut emissions. The new #EmissionsGap Report shows how deep those cuts must be to limit warming and make a return to 1.5°C possible. Explore the findings: https://ow.ly/voCP51002C2

Really interesting.

Many readers have their devices set to "dark mode" and we try really hard to follow a user's preference. If the device or browser is set to dark mode, we show display a much darker version of the map. Here's both desktop and mobile.

On the gfx team @propublica.org, we try to make all of our maps look good on desktop, mobile, dark mode & light mode, which means 4 total versions of a single map! Here's how I approached one of the maps for today's story about fires and flooding in Ruidoso, NM. www.propublica.org/article/wild...

It’s fascinating to look back, especially at ideas that were rejected in the days of cheap fossil energy. My dear friend @mikepage.bsky.social 🙏🏼 sent these fantastic books from 79/83 about SUPER SOLAR HOUSES + NEW INVENTIONS in Low-Cost Solar Heating. I’ll be bringing them along to workshops.

Sales of battery-electric passenger cars have jumped in South Korea this year, 24.3% so far this year compared to 13.5% in the same period last year. The new year's incentives are available from February every year, and they were given a boost this year with e.g. a new car-replacement incentive.

"GERMANY and BELGIUM opposed the exclusive use of the passive voice, saying it gives the impression that both arguments are equally supported and is thus a skewed way of presenting discussions."

"Noting that the IPCC had no official record of the last four meetings, Chair Skea proposed attempting to agree on standardized approaches to reporting."

I finally got down some thoughts about what it's like to be a colorblind cartographer. billmorris.io/shoals/2026/...

As someone who reads transcripts of climate change conferences for a living, and finds their dramatic tension riveting, I am so incredibly psyched that one of them has been turned into a movie 💫 (litterally: it's all verbatim. which is wild & brilliant) www.filmlinc.org/nyff2026/fil...

With less than 24 hours left in the meeting, the Panel is continuing to wrestle with the more substantive issues on its agenda, including its workplan. Panel members are working late into the evening in an effort to achieve consensus. #IPCC ➡️ enb.iisd.org/intergovernm...

"I’m sure someone somewhere will jump into the detailed statistics but I don’t see much to be gained from it. If it’s wrong, it’s wrong, but if it’s right, what does it even mean?" Worth scrolling down. (I saw the paper and a few alarmed posts about it.)

So, here are some fascinating stats... Germany had record BEV sales in Q2 2026 and has the third largest EV fleet in the world that can save it 16 million barrels of oil annually... ...all that at 8.3 TWh of annual electricity consumption, which is just 1.6% of Germany's demand!

Many versions of the current El Niño intensity have been shared… we’ve had to change the colour scale to appropriately show the strength of the anomaly.

I think scientists have a responsibility to not have press releases issued for random papers. Most research isn't meant or ready for general audiences. We should give science enough time to accumulate evidence before we make our problems the society's problems.

The Intergovernmental Panel on Climate Change is beginning its 65th session in Addis Ababa, Ethiopia today. This is a critical meeting for the #IPCC, as the Panel must agree on both a budget for the Seventh Assessment Report and a timeline for delivery of the three Working Group reports. #AR7

Net zero 2050 is a political anchor increasingly distant from the science aligned with our UNFCCC, Paris &ICJ commitments. Simple Q. As we face a cumulative emission challenge & global emissions are still rising, how can we still have the same end date. Each year we fail so the date moves closer.
