California Farmers Turn to Agave Amid Drought Conditions and Climate Change

Most of the United States’ fruits and nuts, like avocados and almonds, come from California. But scientists say human-caused climate change means more extreme heat and intensifying periods of drought for the state. That has led some farmers to seek out less-thirsty crops — like agave.

The succulent has long been grown in Mexico and is the key ingredient in making tequila and mezcal. Agave, though, as a crop is a new idea for the United States. In California, it’s more often seen as part of decorative landscaping.

Hillside Erosion Worsening in California Due to Wildfires and Intense Rain

Over the last three decades, California has seen increasing erosion after major wildfires — a phenomenon that not only endangers water resources and ecosystems, but is also likely to worsen with climate change, according to researchers.

A new study from the U.S. Geological Survey documented a tenfold increase in post-fire hillside erosion in Northern California from the late 1980s to the 2010s, with the majority of the largest sediment-producing fires occurring in the last decade.

Boiling Point: Tech Companies Clam Up About AI’s Climate Costs

Artificial intelligence technology is guzzling water and energy in California and around the globe, yet most tech companies have not been forthcoming about the actual environmental costs of their applications, my colleague Melody Petersen reports.

That’s a huge problem, as their energy and water consumption will undoubtedly strain supplies and drive up demand for climate-warming oil, gas and coal — all while leaving users in the dark about their true contributions.

July was California’s Hottest Month Ever, as Climate Warms to Dangerous New Extremes

The month of July kicked off with a dire warning: A rare, long-duration heat event was forecast to bring extreme heat risk across the West, with triple-digit temperatures and dangerous fire conditions expected in much of California for days on end.

That outlook quickly proved accurate — and would end up defining almost the entire month in the Golden State, which would see little relief from unrelenting heat.

Will Global Warming Turn L.A. into San Bernardino? Map Models Climate Change in 60 Years

Imagine it’s a Saturday morning in Santa Monica in the year 2080. You brew your coffee, open your front door and breathe in the hot, dry air of … San Bernardino?

That’s the potential future if climate change continues unabated, according to a new mapping tool from researchers at the University of Maryland Center for Environmental Science. The tool draws direct lines between an area’s projected climate in 60 years and the places that are experiencing that climate today.

State Water Project Supplies Could Fall up to 23% Within 20 Years Due to Climate Change

Climate change threatens to dramatically shrink the amount of water California can deliver over the next 20 years and could reduce supplies available from the State Water Project by up to 23%, according to new projections released Wednesday by Gov. Gavin Newsom’s administration.

The analysis by the California Department of Water Resources examined a range of climate change scenarios and projected that by 2043 the average amount of water transported through the massive network of reservoirs and canals to more than half the state’s population could decline between 13% and 23%.

WATCH: Tipping Point: Colorado River Reckoning- A PBS News Special

Forty million people depend on the Colorado River for water, but that vital resource is in peril. The river’s storage system has shrunk to an estimated 41 percent capacity as of June 2024.

The river, which irrigates 4 million acres of some of the most productive agricultural land in the United States, may never fully recover due to climate change, according to scientists.

The Water War Between the US and Mexico

The U.S. and Mexico are experiencing another border dispute, and this one is about water. The conflict stems from an 80-year-old treaty where the countries agreed to share water from the Colorado River and the Rio Grande. However, because water is in more demand but scarcer than ever, sharing has not been going to plan.

The U.S. and Mexico signed a treaty in 1944 stipulating that Mexico send 1.75 million acre-feet of water to the U.S. every five years from the Rio Grande, and the U.S. send 1.5 million acre-feet of water to Mexico from the Colorado River each year. But water levels are lower than ever, and Mexico has “sent only about 30% of its expected deliveries, the lowest amount at this point of any four- or five-year cycles since 1992,” said Reuters.

As California Water Agency Investigates Top Manager, Some Worry Progress Could Be Stymied

In the three years that Adel Hagekhalil has led California’s largest urban water supplier, the general manager has sought to focus on adaptation to climate change — in part by reducing reliance on water supplies from distant sources and investing in local water supplies.

Study Says Water Transfer Deal is Raising Dust and Draining the Salton Sea

The Salton Sea is a terminal saltwater lake. It’s a flooded basin with no natural outlet, similar to the Great Salt Lake or the Aral Sea. And the Salton Sea is shrinking.

One of the reasons for that is the Imperial Water Transfer deal that has brought hundreds of thousands of acre feet of water to San Diego over the last two decades. The deal, signed 21 years ago, meant the Imperial Valley began transferring excess water from the valley’s farm fields to San Diego’s water taps.
