This post first appeared on April 24, 2013. Unfortunately, the problem of dust on snow has not gone away. Since I wrote this post, NASA has gotten involved in studying snow on the Grand Mesa. I wrote about the NASA project for FiveThirtyEight. Spring is a nervous time for skiers and farmers. I’m both of these, […]

David Grinspoon is a comparative planetologist and an astrobiologist. He’s also a big book nerd, and his love for both fiction and nonfiction are proudly on display in his own new book, Earth In Human Hands: Shaping Our Planet’s Future. Grinspoon’s book uses insight from the study of the other planets in our solar system […]
The last few days in Washington have been beautiful, springlike. Soft breezes, temperature in the 60s and 70s. Which would be fine, if it were spring. But it is February, and it is not fine. This weather is making me angry. I try to enjoy it, because it’s what we have, and it is, objectively, […]
On the western edge of the Colorado Plateau, in the mountains of central Utah, is a tree that weighs an estimated 13 million pounds—as much as three giant sequoias, or 55 blue whales, or 10,000 grizzly bears. (Hey, I just thought you might like to imagine a pile of 10,000 bears.) This tree is the […]
I joined a film crew several years ago in Chilean Patagonia where we put together a flick opposing dams along the turquoise rivers of the Aysén region. At the time, stopping the advance of some of the biggest investors in the world seemed impossible. But soon more films were made, protests ignited across the country to save […]
This summer, the Bramble Cay melomys, a reddish-brown rodent that resembles a large mouse, made international news. In mid-June, the Guardian reported that the melomys, last seen in 2009, had been confirmed extinct in its only known habitat, a tiny, isolated coral outcrop in the narrow strait between Australia and New Guinea. “First mammal species wiped […]
I must tell you up front that Kathleen R. Walker, second author on “Aedes aegypti (Diptera: Culicidae) Longevity and Differential Emergence of Dengue Fever in Two Cities in Sonora, Mexico,” published recently in the Journal of Medical Entomology, is my stepdaughter. She’s an entomologist, she studies bugs; I occasionally have a bug question. I asked […]
The Alexander Archipelago, a 300-mile-long sweep of islands off the southeastern coast of Alaska, is known for its isolation, its heavy rain, and its thick, ancient forests of hemlock, pine, spruce and yellow-cedar. Yellow-cedar, which John Muir called a “truly noble tree,” has long been prized for its fine-grained, butter-colored wood. But over the past century, as average temperatures have risen, […]
