Impose a Price on Carbon This could occur in several ways. The revenue-neutral carbon fee has a great backbone of advocacy support. It would charge fossil fuel producers at the first point of sale, and the revenue would be distributed among the public. Prices of goods and services dependent on fossil fuels would go up, while people who buy less of those products and therefore contribute less to climate change would come out ahead. The revenue-neutral system’s one flaw, according to some, is that it doesn’t provide government with a new source of revenue for funding social systems that promote renewable energy, sustainable agriculture and other climate-focused measures. A cap-and-trade system, on the other hand, would fund public agencies while creating incentive for industries to pollute less. Republicans, however, tend to oppose cap and trade because it acts much like a tax on businesses that they argue will depress the…

The highest mountains in the West run north-to-south through the Mediterranean latitudes and just 150 miles from the Pacific Ocean—a remarkable stroke of geologic luck that has made California one of the richest ecological and agricultural regions on the continent. These mountains accumulate deep snow in the winter, which in turn feeds cold rivers that flow through the hot, dry months. But the unique conditions that California’s native fish, its farms and its cities depend on are acutely threatened by climate change. In 2015, virtually no snow fell in the Sierra Nevada. Droughts occur naturally, but research indicates the current drought in the American West has been made worse by climate change—and that future droughts will be exacerbated by the warming planet. A 2015 paper published in the journal Geophysical Research Letters calculated that climate change has made California’s current drought as much as 27 percent worse than it would…

If President-elect Donald Trump actually believes all the warnings he issued during the election about the threats of immigration, he should be talking about ways to slow global warming as well. Rising sea levels, caused by the melting of the Antarctic and Greenland ice caps, will probably displace tens of millions of people in the decades ahead, and many may come to North America as refugees. Climate change will cause a suite of other problems for future generations to tackle—and it’s arguably the most pressing issue of our time. A year ago in December, world leaders gathered in Paris to discuss strategies for curbing greenhouse gas emissions, and scientists at every corner of the globe confirm that humans are facing a crisis. However, climate change is being basically ignored by American politicians and lawmakers. It was not discussed in depth at all during this past election cycle’s televised presidential debates—and…

In the Black River south of Carlsbad, N.M., rare Texas hornshell mussels are trying to multiply. It’s a bizarre and complicated process: Male mussels spit sperm into the river, where the females catch it. After brooding fertilized eggs for about a month, they chuck the larvae into the water. There, the would-be mussels hope to be eaten by certain kinds of fish—attaching to their gills and forming parasitic cysts. Then they develop into juveniles before cutting loose from the fish and wriggling to the river bottom, where they can live for up to 20 years. Texas hornshells are native to the Pecos and Rio Grande basins of southern New Mexico and Texas, where they help maintain water quality by filtering out sediment and other particulates. They’re the only surviving species of New Mexico’s eight native mussels, and the stretch of river near Carlsbad is one of their last strongholds. Their…

On warm fall days on the California coast, it’s not uncommon to see the iconic monarch butterfly flitting through the sky. In some places, so many butterflies are present that it makes an impressive display. “The air is filled with orange,” says Samantha Marcum, the monarch butterfly coordinator for the Pacific Southwest region of the U.S. Fish and Wildlife. Marcum, who also works on the Western Monarch and Milkweed Habitat Suitability Model Project, is based near the Lighthouse Field State Beach in Santa Cruz, one of the groves where thousands of monarchs come each winter to escape chilly Western winters. On windy, cooler days, the monarchs can be seen up in the Monterey cypress and eucalyptus trees, clinging to the branches with thread-like legs, stained-glass wings winking in the daylight. In 1997, an estimated 70,000 monarchs came to the grove. At the last count in 2015, that number was down…

In 1922, seven Western states agreed to divvy up the water in the Colorado River, paving the way for giant dams, reservoirs and aqueducts to move and store it. Over the next century, the arid region, prone to erratic storms and punishing droughts, saw farms and cities grow and grow—with the belief that the water they relied on so heavily was inexhaustible. But the Colorado River Compact, as the agreement is known, contained a serious flaw: The states overestimated how much water flowed through the river, which begins high in the Rocky Mountains of Colorado, and runs southwest for 1,450 miles, before entering the Gulf of California in Mexico. In nearly a century since then, roughly 40 million people have come to rely on an allocation of water that doesn’t actually exist. That miscalculation underpinning management of the West’s most-important river is one of the many manmade errors that have…

On the morning of July 23, the city of Los Angeles was covered in a dusting of ash. An apocalyptic haze muted the sun, and the sky was an eerie, unnatural pink. Just a day before, a wildfire had broken out on private land 30 miles northwest, near Santa Clarita. Within 24 hours, the Sand Fire scorched 20,000 acres, and in a week, it burned another 21,000 acres. At least 10,000 people had to evacuate before it was contained by early August. Every day seems to bring another fire. Today, the Blue Cut fire is ravaging the Cajon Pass in San Bernardino County; as of 4 p.m. today, 6,500 acres have burned, with an unknown number of structures damaged. The most volatile fire activity in the West this year has occurred in Central and Southern California—from Big Sur to Carmel-by-the-Sea to San Bernardino—causing the closure of the Pacific Coast Highway,…

On the 10th floor of Xcel Energy’s downtown Denver office building, energy traders sit before banks of screens filled with flickering, colored digits, as they buy and sell electricity for the utility’s sprawling service areas. In one corner, a trader monitors the Midwest wholesale market, and in another, the Southwest Power Pool—an odd name, given that it actually covers the Great Plains, not the Southwest. On a recent day, an electronic map showed North Dakota in blue; the price of the state’s wind power was near zero. On the other hand, southern Indiana was burnt orange, with the price of a kilowatt-hour near 8 cents. Five minutes later, Ohio turned pale green as the price dropped to 5 cents. Meanwhile, on the other side of the room, the trader handling Colorado had no fancy, color-coded price map. When he needed to buy or sell, he had to get on the…

On June 21, a new petition surfaced on the White House’s website. In large bold letters, it reads: “Fire National Park Service Director Jon Jarvis. We deserve a director who will uphold the agency's integrity.” During its centennial year, the agency has fallen under increased scrutiny for not taking swifter action to address a culture of sexual harassment and employee misconduct. The petition was started by a group of recreation and environmental activists in the San Francisco Bay Area and launched a week after members of Congress on the House Committee on Oversight and Congressional Reform grilled Jarvis for failing to take enough steps to stop sexual harassment and hostile working conditions that female employees faced in the Grand Canyon, Florida’s Canaveral National Seashore and other parks. Last month, the Department of Interior’s Office of Inspector General released a report documenting a pattern of harassment at Canaveral, such as unwanted…

When it comes to conservation, energy and many other issues, Donald Trump’s presidential campaign has been a lot of hat and not much cattle. But his son, Donald Trump Jr., recently offered some insights into what his father’s natural-resources policies might look like. While speaking at June a media summit organized by the Theodore Roosevelt Conservation Partnership in Fort Collins, Colo., Trump Jr., an avid hunter and angler, defended keeping federal lands managed by the government and open to the public. He also reiterated his father’s strong support for U.S. energy development, proposed corporate sponsorships in national parks, questioned humans’ role in climate change, and criticized Hillary Clinton for “pandering” to hunters with “phoniness.” U.S. Rep. Mike Thompson, D-California, spoke for Clinton’s campaign at the summit a day later, providing plenty of contrast between the presidential candidates. Trump Jr. has served as an adviser to his father on natural-resources issues…
