California officials today adopted one of the most important and consequential water-saving measures ever implemented by any state, establishing an efficiency standard for new spray sprinklers that will reduce irrigation system misting and overspray that is common around urban landscapes. It’s a huge step given that nearly half of all of California’s drinking water is used outdoors, primarily for landscape irrigation.
UCLA scientists are leading a $10 million project to help California officials make ecologically wise decisions as the state continues to confront the effects of climate change.
The California Conservation Genomics Project, which is funded by the state, will involve conservation biologists, geneticists, ecologists and climate scientists from all 10 University of California campuses, the Lawrence Berkeley National Laboratory and Los Alamos National Laboratory, the UC Natural Reserve System and California State University campuses, as well as officials from state and federal regulatory agencies and nongovernment agencies, such as The Nature Conservancy. It is intended to run through 2022 or 2023.
An unprecedented survey has revealed the loss of about 85 percent of historical tidal wetlands in California, Oregon, and Washington. The report, published today in PLOS ONE, also highlights forgotten estuary acreage that might now be targeted for restoration.
Where West Coast rivers reach the sea, estuaries serve as critical nurseries for juvenile salmon and steelhead as they make the transition from freshwater to the ocean.
With boating season in high gear, efforts continue to protect local reservoirs from aquatic invasive species. Nevada Irrigation District (NID) is working to keep quagga and zebra mussels out of its reservoirs through boater education and a self-inspection program, as well as quarterly monitoring at Scotts Flat, Rollins and Combie reservoirs. No quagga or zebra mussels have been detected, according NID Hydrographer Ashley Vander Meer.
Amid employee shortages, groundwater issues and other challenges, farmers in Monterey County and elsewhere are looking to the tech sector to help them bring their crops to market.
Parker Jones is one of those seeking to help farmers do more with less. Two months ago, he launched a custom-farming operation, Hermanos Automated Services, renting out a weeding machine that largely replaces hand labor in lettuce fields. It’s made by British-based Garford Farm Machinery.
The National Weather Service has issued an excessive heat warning throughout most of interior Northern California for the rest of the week, as the Central Valley is expected to swelter in the mid-to-high triple digits.
The heat warning is in place 11 a.m. Wednesday through 10 p.m. Friday. During that time, highs across Sacramento Valley cities including Redding, Chico, Yuba City, Oroville, Stockton, Modesto and Lakeport are expected to range from about 100 to 110 degrees.
CAISO has warned state regulators that there could be a 4.7 GW capacity shortfall in 2022, in the early evening hours of the annual peak demand events of September. The grid operator has suggested alteration of water cooling laws, as well as increased procurement of resources.
Toxic, blue-green algae blooms that poisoned dogs across the country this summer with deadly results have California water officials on alert for the dangerous bacteria.
The bacteria are blamed for the deaths of three dogs after a swim in a Wilmington, N.C., pond that contained the algae beds, reported Raleigh-Durham television station WTVD-TV on Monday. The North Carolina dogs began having seizures at home and were dead within hours, according to the report. Another three dogs in Austin, Texas perished after swimming in a lake there earlier this month, city officials said.
On April 1 each year, researchers ski and snowshoe out into the high mountains of the western United States to jab stakes into the bright, crystalline snow, checking the thickness of the blanket. But in 2012, many researchers could barely travel on snow to their test sites—and when they got there, there was almost no snow to measure.
2013 was almost as bad. 2014, the same. And in 2015, on the April 1 assessment, many sites across the Sierra Nevada mountains were bald and snowless—the worst snow drought, scientists found, in at least the last 500 years.
Much of the planet sweltered in unprecedented heat in July, as temperatures soared to new heights in the hottest month ever recorded. The record warmth also shrank Arctic and Antarctic sea ice to historic lows.
The average global temperature in July was 1.71 degrees F above the 20th-century average of 60.4 degrees, making it the hottest July in the 140-year record, according to scientists at NOAA’s National Centers for Environmental Information. The previous hottest month on record was July 2016.
