Myth: Downpours have always happened. Rainfall isn’t changing.
Truth: Warmer air holds more moisture — about 4% more per 1°F of warming.
When storms form in warmer air, they can produce heavier rainfall.
A nationwide analysis of 1,700 U.S. weather stations shows a clear shift toward heavier rain in recent decades.
When it rains, it pours — more than it used to.

Boulder was a powerful classroom this week.
From the Flatirons to the boardroom, two days with @nature_org’s Global Board, Trustee Council, leadership team, and @nature_colorado offered a chance to learn from Colorado and look ahead with purpose.

As a surgeon, I spent much of my life responding to disease at its most urgent point. But over time, I came to understand that health is shaped long before someone reaches the hospital.

Last week, I had an excellent meeting with Aakansh Yerpude, a rising @Princeton senior and NashvilleHealth summer intern. As a fellow Princetonian, I’m encouraged to see him carrying forward the call to be “in the nation’s service and in the service of humanity” through community health work here in Nashville.

Conservation begins long before policy. It begins with experience.
At The Farm at Sinking Creek, @Virginia4_H students learned through cider making, cornmeal, sheep, oxen, bees, bluebirds, wetlands, trails, and local stories.
Children protect what they first come to know, love, and feel proud to inherit.

More than half the oxygen you're breathing right now comes from the ocean. Today is #WorldOceansDay.

We've already lost half our coral reefs and a third of our mangroves. What I saw diving the reefs of Palmyra Atoll this year made the stakes impossible to ignore.
