In addition to the potential unfolding WUI wildfire disaster in Spokane, WA, numerous other large & fast-moving fires (existing & new) are blowing up under extremely critical fire weather conditions & severe drought conditions from eastern slopes of Cascades eastward into ID/MT.

Bordeaux, France, has now recorded more days above 40°C in 2026 alone than during the entire 105-year period from 1920 (when observations began) to 2025. This is deeply shocking.

"Hence our dismal conclusion: rather than finding that LLMs free us to do a better job of what we were doing before they came along, they shift scientific incentives (and the playing field of academic competition) in ways that compel us to do more and more, faster and faster, less and less well."

1. We—@eduede.bsky.social, @mjcrockett.bsky.social, Kevin Gross, and I—have a new preprint on the arXiv today, based on ideas that emerged during an @sfiscience.bsky.social workshop in November 2024: The unintended consequences of large language models as a labor-augmenting technology in science.

Chaco Canyon in modern New Mexico, a major urbanized cultural center of the Ancestral Puebloan culture between 900 and 1150 AD, has had previously protected areas around it opened up for fracking under a new Trump plan via the Bureau of Land Management, threatening an archaeological and sacred site.

BLM fast-tracks proposal to open Chaco Canyon to oil and gas drilling

The Bureau of Land Management wants to repeal a buffer around Chaco Canyon that barred oil and gas drilling.

Market theory goes like this: even the best of us can fall prey to selfishness and rationalization, so let's arrange society so people acting on their most selfish impulses end up producing benefit for all of us. That'll be easier and more reliable than convincing everyone to be more generous. 1/

A gigantic king, crowned and naked, sits on a lavishly curtained stage in a 19th century ballroom, before many ranked men and women dressed as gentry.

If you don't drill for oil or gas this year, it will still be around next year. If you destroy an irreplaceable treasure this year, it won't be around anymore or ever again. This asymmetry suggests erring on the side of protection of irreplaceable assets. www.npca.org/articles/114...

We tend to think of EVs as just transportation. Increasingly, they're distributed energy assets. Every battery on wheels can provide backup power, run equipment or help communities during disasters. As millions more EVs hit the road, that resilience scales automatically. #Bettrification #EVs #V2L

How EVs, hybrids are powering China's flood victims via V2L tech

With widespread power outages, residents are turning NEVs into makeshift power stations, giving them a lifeline to the outside world.

June 2026 was the second warmest June on record (after 2024) in the ERA5 dataset, at 1.39C above preindustrial levels. While we expect warmer temperatures later this year as El Niño kicks in, 2026 is now increasingly likely (~86% chance) to be the second warmest year on record.

Many pro astrophysicists receive unsolicited letters from amateurs with new but subtly wrong physics theories, often about relativity and from retired engineers. This cute new paper is a perfect reply & I love how it uses cyclotrons & transponders & radar 🧪🔭 arxiv.org/abs/2605.21660

Relativity for Retired Engineers

We provide some guidance and examples to clear up common misconceptions about special relativity. These misconceptions often come from trying to express the truths of special relativity in Newtonian t...

Just announced: OpenAI plans to lease a 9.2 gigawatt 100% fossil-fuelled data centre on Ohio. Its emissions will be between 20 - 37 MTCO2-e - somewhere between the total grid emissions of France -> Netherlands As much GHGs as 9.5 average coal plants. Will raise US total emissions by 0.5%

OpenAI in talks to lease 10GW data center from SB Energy in Ohio
Data center project on federal land in the state

June 10, 2026 By Georgia Butler  Have your say
OpenAI is in discussions regarding leasing a proposed 10GW data center being developed by SB Energy in Ohio.

The data center project in question is on federal land - owned by the US Department of Energy - at the Portsmouth Site in Pike County, Ohio.40

Really makes no sense to extend the natural gas grid for new residential neighborhoods. A single mile of new gas distribution line can cost $500,000 to over $1 million to install, with maintenance costs compounding over decades. Xcel is funding whole-home electrification for approximately 2,200..

The Last Gas Line: Why Utilities Are Betting on All-Electric Communities

A quiet revolution is reshaping how America builds neighborhoods — and the cheapest infrastructure decision may be the one utilities never make.

"The unexpected boom in home batteries and the equally surprising surge in rooftop solar installations means that Australia’s target of 82 per cent renewables by 2030 – long dismissed as a lost cause by some – is now very much within reach."

"Blows your mind:" Regulator says boom in home batteries and PV puts 82 pct renewables within reach

Regulator says surge in home battery and rooftop PV installations puts the 82 pct renewables target back in reach because it reduces the burden on large scale projects.
