Climate change

U.S. Geological Survey ecologist Dan Fagre is standing behind an interpretive sign that says “Going, going, gone,” as he describes how Glacier National Park’s glaciers have been wasting away over the past century. Each year, when he visits them, Fagre finds newly exposed rock that was once buried under ice. His research predicts that the […]

Last Tuesday I was speeding through the electric-green Montana landscape and hoping for radio or digital cellular reception to tap into the news about President Obama’s climate plan. I was frustrated that I couldn’t hear the story, much less write about it. But it was more than enough consolation to be heading to Missoula to […]

Confession: While my homeland dries, and pillars of smoke pour out of some of my favorite places, I am far, far away in a place where I must jump over puddles in the park and almost swim my way through air thick with oxygen and humidity. I’ve moved my mobile office to Manhattan for a […]

The water gods created haves and have-nots this year, and nowhere more dramatically than in Colorado. In March, after another dry winter, the whole state was biting its nails. Then: Snowpacalypse! An unusually stormy April built up the snowpack in most of northern Colorado to just about average. In the southern part of the state, […]

It’s springtime in the West, that time of year when brooks babble abundantly with snowmelt, cute baby wildlife prance around verdant meadows, blossoms cover tree branches like virgin snow, and it all goes up in flames. Hoping to keep as close an eye on the burning West as I do on my runs and bike […]

There was a time when environmentalists were all googly-eyed about natural gas, primarily because the cleaner-burning fossil fuel was far more climate-friendly than coal – or so it seemed. The Sierra Club and Chesapeake Energy even became allies in the fight to phase out coal. But as tales of tainted water and polluted air emerged […]

There’s a new tool in California that can tell you how dirty your neighborhood is compared to the rest of the state. It’s called Cal EnviroScreen, and zip codes with the worst ozone, particulate matter, diesel exhaust and other contamination are shaded a deep indigo on a state map, where as the cleanest are white […]

In 2005, smog levels in Wyoming’s Upper Green River Basin surprised even the scientists who study one of smog’s primary components, ground level ozone. Ground level ozone is typically a summertime air pollution problem in traffic-ridden urban areas, like L.A., Salt Lake City and Denver. But in sparsely populated Sublette County, ozone that winter was […]

High in eastern Nevada’s Snake Mountain Range, just below treeline, live gnarled bristlecone pines as old as 4,900 years. Core samples taken from the trees have helped researchers understand how the region has changed over millennia. That’s part of the reason why the Long Now Foundation, a San Francisco-based group whose mission is to “creatively […]

In 2008, Canadian researchers made a scary prediction: In our warming world, boreal forests would stop absorbing excess carbon and start contributing to climate change as soon as 2020. What would cause this switch? The mountain pine beetles that have been eating their way though tens of millions of acres of alpine forests, leaving swaths […]

Until recently, the phrase “flash flood” conjured in my mind a racing blue wall of water, or a canyon running red as blood with sediment – a deadly natural force that smells simply and cleanly of earth and rain. But a trip with friends down the San Juan River in southeastern Utah set me straight […]
