Pumping Mississippi River water west: solution or dream?

Pumping Mississippi River water west: solution or dream?

Waves of torrential rainfall drenched California into the new year. Snowpacks in the Sierra Nevada Mountains have swelled to more than 200% their normal size, and snowfall across the rest of the Colorado River Basin is trending above average, too. While the much-needed water has improved conditions in the parched West, experts warn against claiming victory. About 60% of the region remains in some form of drought, continuing a decades-long spiral into water scarcity.

Salt lakes in the American West are turning to dust

Salt lakes in the American West are turning to dust

Last summer, scientists at the National Oceanic and Atmospheric Administration observed dust blowing 85 miles from its source: Lake Abert and Summer Lake, two dried-up saline lakes in southern Oregon. This has happened before: Saline lakebeds are some of the West’s most significant sources of dust. California's Owens Lake is the nation's largest source of PM10, the tiny pollutants found in dust and smoke, while plumes blowing off the 800 square miles of the Great Salt Lake’s exposed bed have caused toxin-filled dust storms in Salt Lake City.

The window of opportunity to address increasing drought and expanding drylands is vanishing

The window of opportunity to address increasing drought and expanding drylands is vanishing

Chile, Argentina and the American West are in the midst of a decade-long, megadrought – the driest conditions those regions have seen in a century. And many areas in Western Canada and the United States are experiencing extreme drought – a once in 20-year event. Drought makes agriculture less productive, reduces crop yields and increases heat-related deaths. It adds to conflict and migration, as marginalized people are dispossessed of their land. In short, it leaves people more vulnerable.

The American West is experiencing its worst drought since 800AD - around the time Charlemagne ruled - according to a newly released study. The ongoing drought has seen lakes, reservoirs and rivers in California fall to record lows, exacerbating wildfires, according to scientists. The current drought is the worst 22-year dry period in the last 1,200 years - dating back to Vikings and Mayans.
