Myth Diagnosis: Hurricanes Don’t Stop at the Coast (opens the original)
Read excerpt
When we hear that a hurricane has made landfall, our attention naturally turns to the coast. But the storm’s danger does not end there.In September 2024, Hurricane Helene came ashore in Florida. Far inland, its rain overwhelmed streams and rivers across the southern Appalachians. Roads washed out. Communities flooded. People near our farm in Southwest Virginia faced devastating damage hundreds of miles from where the storm first reached land.As a doctor, I think about what happens when a flooded
The Antidote to Climate Anxiety Is Agency (opens the original)
Read excerpt

Her answer has stayed with me: “It’s just an additional weight on young people’s shoulders.” We had just come from SCORE’s Connecting the Dots symposium on how the environment shapes student success.Grace knows that weight better than most.

Myth Diagnosis: Why Hydration Alone Isn’t Enough for Heat Safety (opens the original)
Read excerpt
As a doctor, here is what I want people to understand about extreme heat: “Drink more water” is often the first advice we hear.Hydration is critical. But water alone is not a heat-response system.I saw that firsthand in Phoenix, where community leaders, first responders, hospitals, and local organizations are building a more comprehensive approach to heat safety. That means training emergency teams to recognize heat stroke and cool patients immediately. It means operating respite centers where p
