“…poor air quality caused by pollution and wildfire smoke, occupational exposures like those for firefighters and construction workers”

Air pollution, wildfires, toxic exposures for workers - they share a common source: burning oil and gas, and turning them into toxic petrochemicals / products.

if we’re fomenting rage against First Nations because people are being given two years notice to vacate their expiring leaseholds on reserve land then we’ve kind of lost the plot

It's hard to internalize the fact that the administration really does believe the Iraq war was "woke" and that they would be able to easily defeat a substantially more powerful nation simply by being based chads

Salt water laced with cancer-causing chemicals, a byproduct of oil and gas drilling, keeps shooting out of the ground in Oklahoma.

Experts say it means even more wastewater is spreading underground, poisoning the state’s water supply.

100,000 Homes: Housing the homeless saves money? Giving apartments to the chronically homeless can save taxpayer dollars, advocates say

Anderson Cooper: “So it's more expensive to have a chronically homeless person living on the streets than it is to actually subsidize an apartment for them?”

Answer: “Yes, we’re paying more as taxpayers to walk past that person on the street and do nothing.” #HousingFirst #UrbanTruth

Fossil fuel companies withdrew as much water as 110,000 households last year, equivalent to the population of Nanaimo.

#BigTech isn’t far behind, planning to build data centres in B.C. that would “drink” 20 million litres of water PER DAY.

A New York Times headline about EPA rolling back mercury emission rules for coal plants from February 2026.

A New York Times headline about EPA rolling back mercury emission rules for coal plants from February 2026.

Look, this isn’t complicated: mercury, arsenic, lead and nickel are poisonous, whether you voted for this president or not. But don’t worry, EPA admin Zeldin estimates that allowing power plants to release more toxins will save the utility industry ~$78 million/year.

I have only just recently started digging into data centres and water, and the way companies are hiding vital information is beyond belief. It is so, so dodgy.

The entire project to widely popularise the idea these concerns are "fake" makes so much sense in this context

Last Parliament, I worked to pass strong anti-greenwashing rules to stop corporations from making false environmental claims.

Last week, the Liberals and Conservatives joined forces to gut them.

Rather than defending the public, they’re facilitating corporate deception.

Anthropic is a weird cult who think their software has feelings and thoughts and now thanks to their recent marketing campaign (and the credulous participation of a huge number of progressives), a large number of people around you have joined the cult and are drinking from the fountain

Another war. Another fossil shock.

As violence escalates in the Middle East, civilians face devastating consequences. But the energy fallout is already hitting Europe. Gas prices up 50% in hours.

This is what fossil fuel dependence looks like. 🧵

The $ billions needed to clean up tar sands tailings is being massively undercapitalized by these companies, in the hope that they can flee the scene and leave the public holding the bag.

As oil prices spike, investors and governments should push this ‘war windfall’ towards their cleanup funds.
