On the Moral Hazards of Carbon Dioxide Removal
Climate change science involves a lot of math. There's a great deal of calculus, plus all those formulas and models to understand how planetary physics works. But some of the most important climate math is no more complicated than basic arithmetic. Take the remaining "carbon budget" we have to avoid catastrophic environmental changes, divide that by the volume of carbon pollution industrial society pumps into the atmosphere daily, and you get the amount of time we have left. It's not a big number. Seven years and change.

How Best to Protect the Night Sky?
Bill Wren fell in love with the stars in the inky-black skies of central Missouri. In his childhood backyard, he tinkered with his binoculars, gazing at the craters and mountains of the moon. Then, at age 15, Wren moved with his family to Houston. It was a jarring experience—when he looked up at night, he could no longer see the stars. Though he didn't yet have a name for it, this was his introduction to the growing problem of light pollution. Today, one-third of humanity—including 80 percent of Americans—can no longer see the Milky Way.To avoid the bright city lights, Wren would flee whenever he could, driving nearly an hour and a half northwest of Houston, astronomy books and telescope in tow. He began to understand the value of observing a truly dark sky. "It's almost a mystical experience, that sense of being connected, the sense of unity and oneness," Wren says. His early obsession would grow into a lifelong effort to preserve dark skies and one day earn him the moniker the Angel of Darkness.

The River Keepers
When a journalist called Kris Tompkins and asked, “How do you feel that you’re just starting off with this new park and they’re going to build dams on the Baker River?” Kris had no idea what the reporter was talking about. Then she read the newspapers.

Do You Know Where Your Water Comes From?
It wasn’t until she was 26 and had one degree in environmental science and another in water recycling that Nina Gordon-Kirsch learned where the water in her faucet came from. The Mokelumne River, which carries snowmelt from the Sierra through the Central Valley and out to the San Francisco Bay delta, is surprisingly little-known considering how many lives depend on it.

10 Tips for Your First Time Camping in Winter
What good is the warmth of summer, without the cold of winter to give it sweetness?” wrote John Steinbeck. Point taken, but there’s also a certain sweetness to the cold of winter. Cold-weather camping is a great way to savor those tranquil moments and settings only winter can provide—untouched snow-covered landscapes, early nights and early mornings, a warm fire—yet even some experienced campers balk at the prospect.

What I Learned From Wildfire Risk Tools
Wildfire is always on my mind: I live in a wooded rural community in southern Oregon that has been in a drought for several years. Fir trees are dying at an alarming rate, and nearby springs have slowed to a trickle. Since I moved here in 2014, at least two large wildfires have threatened our community; several smaller fires were snuffed out before blowing up.

Plastic Is the New Coal, Says New Report
Your plastic water bottle will likely spend its golden years floating around the Great Pacific Garbage Patch, but its life began thousands of feet underground. How it got from there to you—and why it was made in the first place—has big implications for global climate goals.

COP26: Voices From the Global South Talk Money
Aside from reducing greenhouse gas emissions, funding is a key issue at the annual United Nations climate negotiations. Money from developed nations given to developing nations is vital to fund mitigation and adaptation efforts; that is, to lessen the impacts of climate change and to protect against its future effects.

Facing Intransigence From Manchin, Environmentalists Look for Ways to Slash Carbon Pollution
Last week, Senator Joe Manchin, the Democrat from West Virginia who has made a personal fortune from his fossil fuel investments, pulled the rug out from underneath Democrats’ climate agenda. The senator said he would not vote for the Clean Energy Performance Program, or CEPP, the flagship climate policy of the Build Back Better legislation that would require power companies to rapidly replace fossil fuels with renewables such as solar and wind.

9 Myths About Animals
From the labradors we share our homes with to the legendary sea monsters of Western folklore, we’ve sought to understand our fellow earthlings since the beginning of humankind. Whether it’s superstition, exaggeration, or just plain misunderstanding, sometimes our quest for knowledge can lead to some misguided conclusions. Here are nine widely believed animal misconceptions that don’t hold up to scientific scrutiny.

What Does Cloture Have to Do With Climate Change?
The FY2022 federal budget contains some of the most important climate policy of our lives. Some of it isn’t specifically about climate but will nonetheless have huge impacts on emissions. The construction of affordable housing in the nation’s increasingly unaffordable cities, for example, will help low-income people who are most likely to have old cars with terrible emissions drive less—or not at all. Making existing affordable housing more energy efficient is sound climate policy as well as an anti-poverty measure. Other aspects of the budget, like the maybe-it’s-dead-and-maybe-it-isn’t Clean Energy Performance Program (CEPP), are clearly aimed at cutting fossil fuel emissions (more on that below). All of these proposals have been designed to fit into a reconciliation bill—an arcane, complicated form of budgeting that Congress resorts to when all is not harmonious in the halls of government.

We Don't Deserve Beavers
Tar Creek doesn’t seem like an inviting home for wildlife. For more than 70 years, miners blasted open the earth underneath the Oklahoma waterway in search of lead and zinc. Today, mountains of waste material from the mines tower above what is now classified by the EPA as a Superfund site. Groundwater that flows through the abandoned mines flushes toxic heavy metals, including cadmium and lead—both potent neurotoxins even at low concentrations—into the creek. The water runs bright orange.
