Over 50 fire ecologists across the Western U.S. took an unprecedented look at how forests in thousands of locations are recovering from fire in a changing climate. The results were alarming.

Less than a century ago, Colorado hunted, trapped and poisoned all the wolves within its borders. Today it’s restoring them – a change that reflects a profound shift in human thinking.

Fifty years ago, the Salton Sea was a draw for boaters and fishermen; today it’s an ecological time bomb. Two water experts who served on a state review panel describe its proposed rescue plan.

Wildfires are remaking western US forests. Decisions about managing forests that have burned should factor in how fires change animal behavior and interactions between predators and prey.

Stemming the water crisis in the western US will require cities and rural areas to work together to make water use on farms – the largest source of demand – more efficient.
The white ‘bathtub ring’ around Lake Mead, shown on Jan. 11, 2022, is roughly 160 feet high and reflects falling water levels.

A Western scholar proposes allocating water from the Colorado River based on percentages of its actual flow instead of fixed amounts that exceed what’s there – and including tribes this time.

Monsoons are weather patterns that bring thunderstorms and heavy rains to hot, dry areas when warm, moist ocean air moves inland. They’re challenging to forecast, especially in a changing climate.

Cities and farmers in the Southwest are resorting to unsustainable strategies to pull in more water. Iran has tried many of these strategies and shows how they can go wrong.

The US has learned that it cannot suppress its way to a healthy relationship with fire in the West. That strategy failed, even before climate change proved it to be no strategy at all.
Heat and dryness are leaving high mountain areas more vulnerable to forest fires.

The area’s iconic national parks are home to grizzlies, elk and mountain snowfall that feeds some of the country’s most important rivers. A new report show the changes underway as temperatures rise.
Colorado’s East Troublesome Fire jumped the Continental Divide on Oct. 22, 2020, and eventually became Colorado’s second-largest fire on record.

Scientists studied charcoal layers in the sediment of lake beds across the Rockies to track fires over time. They found increasing fire activity as the climate warmed.
