Vice President Kamala Harris on Monday will visit Lake Mead in Nevada to highlight the problems caused by Western drought. 


U.S. officials have approved a long-lasting fire retardant that could significantly aid in fighting increasingly destructive wildfires. The U.S. Forest Service on Tuesday approved Perimeter Solutions' fire retardant that is intended to be used as a preventative measure and can last for months. It's similar to the red-dyed retardant dropped from aircraft, but it is clear and lasts much longer. The company says its primary use will be by industrial customers such as utility companies and railroads, but can also be used at residential and commercial properties.


U.S. hydropower generation is forecast to drop 14% this year compared with 2020 as drought grips vast areas of the West. Experts say the reductions complicate grid operations since hydropower is a relatively flexible renewable energy source that can be easily turned up or down, such as in the evenings when the sun goes down and solar energy generation drops. The projected declines in hydropower are concentrated in the West, with California's production expected to fall by nearly half. Declines in hydropower production mean bumps for other energy sources, such as natural gas.

The Colorado River Basin is enduring two decades of drought, and water shortages are on the horizon. But scientists say this isn’t the worst-case scenario. The region has undergone longer, deeper droughts in the past. KNAU’s Melissa Sevigny spoke with paleoclimatologist Matt Lachniet of the University of Nevada-Las Vegas about how knowing the past can help us plan for a warmer, drier future.
