On Thursday, Metropolitan Water District of Southern California (MWD) Chairman Adán Ortega and Interim General Manager Deven Upadhyay addressed collaboration between two of the largest wholesale water agencies in Southern California in light of MWD’s major long-term planning effort. This process aims to chart a course for meeting Southern California’s water resource management needs while […]
The California Department of Water Resources performed its fourth snowpack survey of the season on Tuesday, April 2, confirming that the early winter’s “snow drought” gave way to a slightly above-normal snowpack following a series of storms. DWR’s early April snow survey marks what is considered the peak snowpack for the year in the Sierra […]
After more than two decades of drought, water utilities serving the largest urban regions in the arid Southwest are embracing a drought-proof source of drinking water long considered a supply of last resort: purified sewage. Water supplies have tightened to the point that Phoenix and the water supplier for 19 million Southern California residents are […]
Millions of dollars in federal aid are still available for low-income water customers in San Diego County to cover overdue residential water and wastewater bills. The San Diego County Water Authority helped secure the federal funds — and the deadline for applications has been extended to March 31, 2024. The Low-Income Household Water Assistance Program […]

The start of wine grape growing season in California’s Napa Valley now comes nearly a month earlier than it used to because of the region’s warming climate, according to a new study from a team led by UC San Diego Scripps Institution of Oceanography researcher Dan Cayan. The research, published online in the International Journal of […]
Across the western U.S., many areas received record or near-record amounts of snowpack over the winter. With the spring and summer temperatures melting the abundant snow, a record volume of streamflow has been recorded in several basins in the southwestern U.S., providing more water for the area later into the summer than is typically seen. […]
A new study from UC San Diego Scripps Institution of Oceanography researcher emeritus Peter Bromirski uses nearly a century of data to show that the average heights of winter waves along the California coast have increased as climate change has heated up the planet.

June 2023 was record hot for some parts of the U.S., while other locations were roiled by severe weather and poor air quality, according to NOAA’s National Centers for Environmental Information. Heat waves led to record high temperatures in Puerto Rico, the Northeast, Mid-Atlantic, Great Lakes, Texas, and Louisiana. Thick smoke from Canadian wildfires created […]
The 2022–2023 snow season started off relatively active across the West, with a few modest storms bringing snow accumulations to the mountains in early November. By the start of December, snow water equivalent (SWE) across much of the region was above normal. Starting in early December, several storm cycles brought moisture-laden families of atmospheric rivers […]
Carbon dioxide levels measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory peaked at 424 parts per million (ppm) in May, continuing a steady climb further into territory not seen for millions of years, scientists from NOAA and Scripps Institution of Oceanography at UC San Diego announced today.
