"Climate and Energy Minister Chris Bowen has said he will use federal power to force the Queensland and NT governments to fall into line with his plan to require data centres to fully offset their electricity use with investments in renewable energy." Good. www.smh.com.au/environment/...

‘We will use all the powers available’: Bowen lays down law to states on data centres

Energy Minister Chris Bowen insists the data centre boom and his plans to drive down Australian emissions can co-exist.

I had two A+ immigration lawyers, the full backing of the Massachusetts Institute of Technology, and direct support of Jon Ossoff and Raphael Warnock's teams, and I still lost half a year of my life, three speaking opportunities, and tens of thousands of dollars in wages. Imagine a normal person.

My column on how capital becomes a death cult. Faced with a choice between profit and human life, the radical right chooses profit. Then it tries to persuade us that mass death is what we want. It's the new phase of climate denial: accept your fate, earthlings. www.theguardian.com/commentisfre...

Murderous heat, an endangered food supply, decimated landscapes: embrace the Mediterranean life | George Monbiot

As climate disaster stares us in the face, the radical right says ‘Embrace the Mediterranean life’. Embrace death, more like it, says Guardian columnist George Monbiot

Depicting Jewish people with horns is a centuries-old, dehumanizing, antisemitic trope. Democratic Gov nominee Phil Weiser is outspoken about his mother’s birth in a Nazi concentration camp, his family members killed in the Holocaust, and the threat posed by antisemitism today.

Alexandra Fasulo runs one of the most prolific anti-solar campaigns online, regularly telling over 2 million followers renewable energy is threatening farms and wildlife. But how much of her rhetoric is actually true? @alexhannaford.com spent months parsing through the nuance for HEATED:

The influencer teaching millions to fear solar

Alexandra Fasulo says she’s protecting farms and wildlife. Her campaign is becoming a blueprint for the fossil fuel right.

Not to dunk on this but it isn't really true that the Hormuz oil crisis is driving a solar boom. Here's this chart updated to June of China solar exports, showing that the March spike in exports has subsided and was therefore mostly just export tax rebate effects.

Chart from BloombergNEF and SinoImex showing monthly dollar-value exports of solar cells and modules from China, by market, from November 2024 to June 2026. They spiked to $4.5bn in March 2026 because a key China export tax rebate was removed, fell to $3.1bn in April - still high but possibly due to some spillover effects and deadline missing - and then are back to a normal-ish level of $2.2bn in May and $2.5bn in June.

Absolutely unbelievable how solar power has taken off worldwide during the Hormuz oil crisis. You don't have to hand it to him, but Trump may have done more to finally kick off a global civilization of effete librul solar users than anyone else in the West

Chart showing solar panel exports from China (the main solar panel maker by a long shot) growing steadily & mightily from 2018 through 2026, then spiking by almost 2x in March 2026.

Was trying to do an annual update, but it has come to my realization that Trump wiped everything between FY2024 and FY2026 from the USCIS H-1B Employer Data Hub. @thexylom.com now has one of the last independent copies of data re: H-1B skilled workers in America's top higher education institutions.

EXCLUSIVE: A new analysis by The Xylom's @alexip718.com shows for the first time just how much America’s top research institutions have grown to depend on H-1B skilled workers — and how this delicate balance might be disrupted by U.S. President Donald Trump’s crackdown on legal immigration.

Unfortunately, it is likely that smoke from the fires in Washington and Oregon get pulled westward over the Pacific Ocean, down the coast and toward the Bay Area by Wednesday. Other parts of Northern California, like Tahoe, could get smoke as early as Tuesday.

The emergency response to Spokane fires has been exemplary and heroic. We also need to remember this isn’t the limit of our ability to reduce wildfire risk. After 100 years of strict fire suppression, millions of acres of WA forest need fuel reduction treatments like prescribed fire & thinning.

Here’s the thing that frightens me. Everyone executed their roles almost perfectly in the response to these fires and it was still this bad. Everyone. Responders, city, county and fed officials. Detection and warning systems. Everyone did their jobs very well. This was a best case outcome.

I'm not sure folks have realized just how crazy the second half of 2026 and 2027 will be for global temperatures – on the back of a record-smashing El Niño event. Here is my latest estimate of where both years will end up compared to global temperatures since 1850.

I can’t afford gas or groceries and Trump won’t allow disaster relief to my state because our governor is a Democrat. But at least the federal government is banning workplace heat protections.

Absolutely surreal to see my hometown become the latest wildland urban interface fire conflagration. My heart goes out to everyone who lost homes, property, pets, and the hardworking local journalists doing their best to get reliable info out in the chaos. www.spokesman.com/stories/2026...

Wildfire in northwest Spokane destroys 640 structures

The Old Trails wildfire in northwest Spokane destroyed 640 structures Saturday, according to Cody Rohrbach, Spokane County Fire District 3 fire chief.

...like anything you do in the early part of your career, it shaped the way I think. Doing science well requires you to train your brain to be hyper skeptical of yourself. Asking honestly what the data tells you is VERY different from asking what part of the data confirms your pre-existing belief.

One key thing about reactionary centrism is that if you argue for the conservative position on purely savvy electoral grounds long enough ... you start to just believe the conservative position. I'm watching this happen in climate as the RC brigade becomes more & more explicitly pro-fossil fuels.

It was inevitable that reactionary centrists would turn against harm reduction and call for a return to mass incarceration

It's important not just to memorialize people's professional achievements, but also the kind of people they were. This article detailed serious sexual assault allegations against Nims Purja, which the NY Times repeated in its reporting of his death, but many outlets did not.

Women are increasingly reporting sexual harassment and abuse in the sport, including accusations against the renowned climber Nirmal Purja.

How did Denmark get from basically 0 to 80% new sale of EVs in 5 years? Here’s my slides from a recent presentation on what I think has been instrumental in achieving this.

#GlobalHeating greatly increases #wildfire risk. That‘s been established scientifically for a long time (see IPCC reports) but has now been shown again for the current fires 🔥 in France and Spain in a new World Weather Attribution study. www.worldweatherattribution.org/climate-chan...
