Red Mountain Pass, Colorado – Cosmic rays come from outer space. These high-energy particles, which emanate from the sun but also from beyond our galaxy, travel across the universe, nearly at the speed of light, to reach Earth. Our atmosphere and magnetic field shield us from cosmic rays, but secondary particles shower down and reach ground level.

April 1, the midpoint in the water year, is an important milestone for scientists, water managers, and others who track the American West’s snowpack. Each watershed has its own typical peak date for the snowpack, but in many places, April 1 has been a traditional moment for taking stock of how the spring snowpack is stacking up. Accordingly, I’ve collected a variety of maps and charts below that illustrate the state of play on April 1.

Here’s a story I just wrote for The Water Desk, a program at the University of Colorado Boulder’s Center for Environmental Journalism that I co-direct. I can’t vouch for its shelf life in the Trump administration, but the U.S. Environmental Protection Agency continues to publish a revealing set of indicators of climate change impacts, including 14 connected to snow and ice.

I can’t vouch for its shelf life in the Trump administration, but the U.S. Environmental Protection Agency continues to publish a revealing set of indicators of climate change impacts, including 14 connected to snow and ice. These data sets, many of them visualized with simple maps and time-series charts, show the unmistakable effects of warming and cover a wide range of subjects, including public health, ecosystems and oceans.

Sometimes snow falls when the air temperature is warmer than water’s freezing point of 32° Fahrenheit. Figuring out the dividing line between rain and snow has long flummoxed forecasters, especially in places like the high country of the American West, where complex topography and dramatic elevation differences shape the weather. The fuzziness of the boundary can have life-or-death implications. If rain falls on top of snow, that can cause disastrous flooding.
