Who really pays when climate disasters strike?

On October 5, 2026, the Supreme Court heard oral arguments in Suncor Energy v. County of Boulder, an 8-year legal battle that started when Boulder County sued ExxonMobil and Suncor in 2018. The case centers on the 2021 Marshall Fire — a blaze driven by 100 mph winds that destroyed 1,084 buildings, killed two people, displaced 37,000 residents, and left behind an estimated $2 billion in damages. The core question: should fossil fuel companies pay for climate-related harms they allegedly knew were coming?

For physicians, this isn't abstract. Wildfire smoke, extreme heat, flooding, and expanding tick and mosquito ranges are already driving up emergency visits, hospitalizations, and long-term health burdens — costs currently absorbed by patients, taxpayers, and health systems. Drawing a direct parallel to tobacco litigation, advocates argue that just as state attorneys general held cigarette makers accountable through the 1998 Master Settlement Agreement, fossil fuel companies should bear their share of climate costs.

Key Takeaways:

• Research published in Science (2023) found Exxon's own scientists accurately projected global warming as early as the 1970s–80s
• A ruling for the companies could shut down dozens of similar state and city climate lawsuits before trial
• Post-fire studies found more than half of surviving Boulder residents reported persistent health symptoms — including headaches, sore throats, and unusual taste — months after the fire

Why it matters: If the Court sides with Suncor, communities and health systems may be permanently locked into absorbing the costs of climate damage — with no legal pathway to hold polluters accountable.
