In 2023, Canada's wildfires turned the sky over New York the color of a traffic cone. In July 2026, it's happening again.

Everyone covers the smoke in our lungs. Almost nobody covers what that same smoke does to our drinking water and lakes. This episode traces the whole chain: the light-blocking, algae-fertilizing double effect of ash on a lake surface, the "lake that turns to tea" carbon browning problem, the neurotoxin that works its way up the food chain into the fish on your plate, and what all of it means for the water coming out of your tap.

I also talked to a silvicultural forester with the U.S. Forest Service (speaking personally, not for the agency) about the century of fire suppression policy sitting underneath all of this, and about a genuinely strange soil chemistry mechanism that turns a burned hillside into a mudslide waiting to happen.

And yes, we go there on the oil and gas question: how much of this traces back to Alberta's oil sands, what the actual peer-reviewed attribution science says, and where that research runs out.If 2023 felt like a freak year, 2026 is making a strong case that this is just what North American summers look like now. For us, and for our lakes.//
