Systematic attribution of heatwaves to the emissions of carbon majors - Nature Climate change made 213 historical heatwaves reported over 2000–2023 more likely and more intense, to which each of the 180 carbon majors (fossil fuel and cement producers) substantially contributed.

🚨 Important paper in Nature: "Systematic attribution of heatwaves to the emissions of carbon majors".

We don’t need costly “miracle technologies” like carbon capture or SMRs to solve the climate crisis, air pollution, or energy insecurity.

As @mzjacobson.bsky.social argues in our latest article, we already have the solution: wind, water, and solar energy.

Duquesne Light: Restoration expected to take 5 to 7 days after 'unprecedented' storm Mayor Ed Gainey said there are 400 additional crews headed to the area, and 70 already called in to aid Duquesne Light.

Chaos in Pittsburgh, and it will be raining for the next week too 😪 lucked out with power, but our internet cables have been ripped off

Our biositing.jbei.org tool has AI integration & some interesting stuff on permitting 🥳 Unexpected challenge: the LLM's heavy use of quotation marks. I promise that we do not mean 'water quality' & 'hazardous waste' ironically. The formatting is just a work in progress.

Cutting scientists from federal agencies means fewer experts tracking extreme weather, monitoring air & water quality, and protecting communities from disasters.

This puts lives, the economy & national security at risk.

This is Brazil celebrating the Oscar for Best International Feature Film for I’m Still Here 🎉 #Oscars

The Year’s Most Urgent Best Picture Contender Is the One Almost No One Has Seen I’m Still Here has a warning—and a reason for hope.

I wrote about why the most important Oscar nominee is the movie about how living under authoritarian rule can feel surprisingly normal.

Best international feature film!!! 🇧🇷🇧🇷🇧🇷🇧🇷 Que orgulho

📣Today, DOE released the 45ZCF-GREET model. This follows the UST/IRS guidance on the Clean Fuels Production Credit (section 45Z) released on Jan. 10, 2025. Now time for me to go collapse on the couch.

Fuel loading driven by a wet period followed by rapid onset drought (in an otherwise longer-period of drought) is a big driver of wildfire cycles. Throw in intense winds and a bunch of humans, and well, that’s one way you create a disaster.

It's never the weather.

It's always the infrastructure and maintenance.

That's right - you have direct payments for grazing land but also the payments for the crop land used upstream for feed. Here is the paper for more: www.nature.com/articles/s43...

So interesting, and so important. I was thinking about this a lot when I was researching about habitats for pollinators so they can help pollinate cropland. But really, we should also be thinking about their wellbeing and allow them to live their (very fascinating) lives.

New Carbon Negative Shot report just dropped 🎉 It's 137 pages of everything you wanted to know about what's hard in CDR and where we can improve. Survey results, waterfall plots, wonky technical details. Truly multi-lab collaboration at its best. www.energy.gov/sites/defaul...

Public library energy is the best energy. Like here is all the knowledge we could find, it's been meticulously organized and vetted and it will cost you nothing today, welcome to the absolute pinnacle of human civic evolution, feel free to pull up any bean bag chair you like

Global heating makes hurricanes like Helene twice as likely, data shows Analysis shows Gulf’s heat that worsened Helene 200-500 times more likely because of human-caused global heating

What many people don’t realize is that global temperature records only reflect 1% of the total increase in the earth’s heat content.

89% of this heat is going into the ocean where it's contributing to rising sea levels, deadly marine heatwaves--and stronger & more rapidly intensifying hurricanes.

Hurricanes Have a Longer, Deadlier Tail Than Anyone Thought New research published today in Nature shocked even the study’s own authors.

The effect on economic drivers (infrastructure, budget allocations, income, etc) on every level, from national to state to city to household increases the number of hurricane-related deaths long after the event. Very interesting read! We definitely need more systems-level studies of disasters.

Graphic from Show your Stripes for the city of Curitiba, Brazil, showing the temperature change relative to average of 1961-2010.

The historical average of maximum temperature for September in my hometown of Curitiba is ~70 F. Today it is reaching 89 F! (it's spring)

I know people assume Brazil is hot. But in the south the weather was quite mild. This heat wave is crazy (and 7th in 2024)

Graph of fatality rate in car collisions vs. weight of one of the cars. Fatality rate for that car drops with weight, almost plateauing above 4000 lbs. Fatality rate for the other car steadily rises.

The heavier your car, the safer you are in a collision, but the more damage you do to the other car. There’s an optimal weight that minimizes total fatalities: ~4000 lbs., the Economist estimates from police reports from 14 U.S. states. (Curb weight, I think.) 🧪 www.economist.com/interactive/...

‘Losing Noah’s Ark’: Brazil’s plan to turn the Pantanal into waterway threatens world’s biggest wetland Hidrovia project to dredge Paraguay River and build ports may destroy vast biodiversity and refuge of jaguars, giant otters and armadillos – and an age-old riverine way of life

The Pantanal, the largest wetland on Earth, stretching across Brazil, Paraguay, + Bolivia, is now at risk from 'progress'.

Being home to a great wealth of biodiversity like jaguars, and a massive carbon sink, seems not to count.

'The legacy of colonialism in scientific research includes an intellectual property system that favors Global North countries & the big corporations they support. This unfairness shows up in who gets access to the fruits of science and raises the question of who science is designed to serve or save'

Capitalism is killing the planet – but curtailing it is the discussion nobody wants to have If life on our one and only planet is to be pulled back from the brink, the time for voluntary ecological measures from businesses has surely passed

How the most powerful environmental groups help greenwash Big Meat’s climate impact Factory farming is terrible for the environment. Environmentalists are sharply divided over what to do about it.
