How Eating Meat Can Reverse Climate Change

Here’s a surprising take from Michael Pollan on how raising cattle differently could actually reverse climate change rather than worsen it. This is the first in a series of articles Slate (and others) will publish this month on “Food and Climate Change: Connections and Solutions.” I further explore the power of photosynthesis to reverse climate change later in the series:… Read more

Can Nuclear Power Save the Climate?

Nuclear power sounds, at first blush, like an answer to climate change, and even some genuine climate heroes (e.g., James Hansen) endorse it. So does a new documentary, “Pandora’s Promise.” But the realities of nuclear energy, especially its inseparability from nuclear weapons, are far less encouraging and lead me to oppose nuclear, especially when we have so many cheaper, safer alternatives–solar, wind and better energy efficiency–that are already cutting greenhouse gas emissions much faster than nuclear could. I explain further in a piece I co-authored with Terry Tempest Williams for The Nation:… Read more

I Got Shot in New Orleans

I was attending a “second line” street parade in New Orleans on Mother’s Day when pistol shots rang out just a few feet behind me and the crowd quickly scattered. The shootings sent 20 people to the hospital. I was lucky: I only got shot in the leg, and since the bullet miraculously didn’t hit any arteries, veins, nerves or bone, the doctor decided to leave it in there. Alas, another journalist, Deborah Cotton of the local weekly paper, “The Gambit,” was much more seriously wounded, eventually losing a kidney in surgery. But I refuse to allow this deplorable incident to turn me against the magical, essential city of New Orleans. And, as I argue in this piece for The Nation, you shouldn’t make that mistake either. America needs a New Orleans that works…. Read more

The BP Oil Spill Cover-up

On the third anniversary of the Gulf of Mexico oil disaster, Newsweek (and equivalent publications overseas) releases my investigative expose of how BP covered up the full extent of its crimes. Never-before-published information reveals that BP knowingly sacrificed the health of clean-up workers, coastal residents and the Gulf ecosystem for its public relations goal of making the oil spill disappear, at least from the world’s TV screens:… Read more

Climate Lessons of “The Year Without Summer”

My review of the new book, The Year Without Summer, explores the lessons offered by the extraordinary developments of 1816, when a massive volcano spewed enough sunlight-blocking detritus into the sky to plunge much of the Northern Hemisphere into chilly darkness:… Read more

The New Yorker and Climate Adaptation

A recent article in The New Yorker about how New York City can better prepare for climate change in the wake of Hurricane Sandy made some useful observations but unfortunately missed most of the larger point, I argue in this Letter to the Editor:… Read more


Latest Book


By now, almost everyone knows what Edward Snowden did: leak top secret documents revealing that the US government was spying on hundreds of millions of people around the world. But if you want to know why Snowden did it, the way he did it, you need to know the stories of two other men.

The first is Thomas Drake, who blew the whistle on the very same surveillance ten years before Snowden did and got crushed. The other is The Third Man, a former senior Pentagon official who comes forward in this book for the first time to describe how his superiors repeatedly broke the law to punish Drakeā€”and unwittingly taught Snowden how to evade their clutches.
