Wind and solar came close to surpassing global gas power generation in April, for the first time, writes @timsmedley.bsky.social.

As Bill McKibben says, “Everything is going wrong, except this one big thing.”

A bloc of oil-producing states with powerful petrochemical interests is distorting scientific findings and opposing any controls on new plastics.

Preventing a weak treaty was a victory for those advocating strong, binding measures regulating plastic production.

UN politics won’t deliver an ambitious plastics treaty
Negotiators again failed to finalize the text for a global plastics treaty in Geneva in August 2025. The talks exposed two harsh truths. Consensus on the treaty text, where no state formally objects, ...

In food history, we notice how super-refined foods--gelatin, vienna sausage, white bread--lose class and become horrifying once they become industrialized. Suddenly, fingermarks in bread dough demonstrate skill, not clumsiness.

Post-chatGPT, I'm feeling this about writing. Smoothness feels gross.

Microplastics are now so ubiquitous we're drinking, eating, and inhaling them. As a result, they're showing up in our stool, placentas, reproductive organs, and brains. Now these particles, less than 5 mm in size, have been found deep within our bones.

Another #plastics recycling facility on fire, this one hosting waste "exported" by the UK to Turkey. A terrible case of #wastecolonialism and a huge health hazard to those downwind and ultimately, all of us, as many of the pollutants will enter the food chain. www.linkedin.com/posts/sedat-...

"...We are making & discarding so much plastic that it has become a substantial component of the global carbon cycle..." Aron Stubbins (The Plastics Center at Northeastern University) on Pang et al's piece on plastics & the marine carbon cycle in NatureSustainability

Plastics in the marine carbon cycle - Nature Sustainability
Marine plastic pollution is a growing problem threatening ocean ecosystems. Now research explores how these plastics may be impacting the ocean’s ability to offset anthropogenic carbon emissions.

it's good...but that 7.5 bn could be better targeted. The pacific garbage patch is only a tiny % of the plastic entering the ocean. Targeting the source at rivers is far more important.

Microplastics are less than 5mm. Primary microplastics are pellets, microbeads, capsules, or fibers. Secondary microplastics are larger pieces of plastic that have broken apart when exposed to sunlight, salt, and wave action. #WetTribe #TidetotheOcean #Microplastics #Microfibers

Reminds me of one of my favorite quotes from a video game:

"Are all the accomplishments of humanity fated to be nothing more than a layer of broken plastic shards thinly strewn across a fossil bed, sandwiched between the Burgess Shale and an eon's worth of mud?"

"Crucially, the Chinese coal-conversion industry is set to expand even further, potentially offsetting declines elsewhere in the country, including a reduction in coal demand to produce cement and steel."

COLUMN: Largely unnoticed, the Chinese coal-to-chemicals industry has reached gargantuan proportions.

If it was a country, it would rank as the world's 3rd largest coal consumer. That as big implications for climate and energy policy.

Indigenous Agta elders are involved in efforts to rebrand the image of the critically endangered Philippine crocodile.

Conservationists warn that without stable funding and stronger government support, even successful grassroots efforts may not ensure the species’ long-term survival.

DUNOY, Philippines — In the dense, tropical rainforests of the Northern Sierra Madre Natural Park, an ancient predator drifts silently beneath the surface of still rivers. For Indigenous Agta elders,…

I found this history fascinating, especially how the US under Bush I a) pushed to create the IPCC to center government representatives, not scientists, in UN climate action; b) used the IPCC to block binding emission targets and carbon taxes on rich countries, which seemed imminent in 1988.
