The Particle

Inhalation

By David Kern— May 5, 2026

When a house burns alongside a forest, the smoke is different. PVC siding cracks into dioxins. Couch foam becomes hydrogen cyanide. A pressure-treated deck releases arsenic in its most toxic form. The emission factors run a hundred thousand times higher than wildland fire. All of it rides upward on carbon particles smaller than a red blood cell, and the particles don't settle. They travel.

Your body has defenses for this. Mucus, cilia, macrophages stationed at the end of the airway. They were built for something ten times larger. The membrane between your air and your blood is half a micron thick, thinner than the particle itself, and it was never designed to close.

The Ritual

The Number

By David Kern— May 5, 2026

The first thing I do is check a number on my phone. Before coffee, before the kids are up. A colored dot tells me whether my daughter can go outside. Whether I run. Whether we open the windows or tape a furnace filter to a box fan and listen to it work all day.

The number goes up for most of a week. School closes, the dog stops going out, I drive to the pharmacy with the windows up. By Thursday I've stopped deciding things for myself. I just check, and the number decides.

The Receipt

Your Receipt: $11.20 Per Ton of CO2 Emitted (Wildfire Smoke Mortality, U.S. Only)

ITEM: Premature death via PM2.5 inhalation, contiguous United States, projected 2020–2100. Quantity: 64,000 annually at 3°C warming. Unit price: value of statistical life. SUBTOTAL: $11.20/ton CO2. Applied to existing social cost of carbon, this represents a 74% surcharge.

Thank you for your emission.

Items not scanned: morbidity, cancer, cognitive decline, reproductive damage, psychiatric injury, non-PM2.5 pollutants. Deaths outside U.S. borders not scanned. Rural counties below 20 deaths/year fell under the register's minimum. Firefighters and farmworkers were not in the system.

No returns. Confidence interval includes zero.

TAKE NOTE

Age burden: Seniors are 16% of the U.S. population but absorb 75% of wildfire smoke health damages. The receipt does not itemize this.

Racial erasure: Native American and Black communities bear the highest per-capita damages within most age groups, invisible inside the aggregate dollar figure.

Dead register: The Trump administration is dismantling the social cost of carbon metric this $11.20 surcharge would attach to. The line item has no bill.

Cancer gap: A 2026 study linked wildfire smoke to lung, colorectal, breast, bladder, and blood cancers. None were priced. None were scanned.

Ghost data: The value of statistical life underlying this figure derives from wage-risk surveys of workers conducted between 1974 and 1991.

The Expansion

Six findings from early 2026. Six different research teams measuring six different things: hours, cancers, deaths, chemistry, elevation, dollars. None were coordinating. They all found the same thing.

Below is a dashboard. One number per card, one source, one sentence. We built it this way because smoke no longer fits inside a narrative. It is expanding along every axis anyone knows how to measure, all at once, faster than the last time anyone checked.

The constraint is the point. A paragraph would let you look away. A dashboard won't. Read top to bottom. Every dial is turning the same direction.

Burning Hours

Fires No Longer Sleep Through the Night

Nights are warming faster than days, breaking the diurnal off-switch that once let wildfires rest; North American potential burning hours rose 36% between 1975 and 2024.

Cancer Link

Five Cancer Types Now Linked to Smoke

In a 91,460-person trial presented April 2026, three years of population-level wildfire smoke exposure registered across lung, colorectal, breast, bladder, and blood cancers. Not yet peer-reviewed.

Projected Deaths

Sixty-Four Thousand U.S. Deaths Projected Per Year

At 3°C of warming, smoke kills an estimated 64,000 Americans annually, 60% above 2011–2020 levels, a projection that already accounts for the fact that burned forests can't burn twice.
