Now there’s emerging research to suggest that cosmic rays, or positively charged, high-energy particles from space, might be the mechanism that flips the switch between phases. Cosmic rays come from outside our solar system, but the number and intensity that reach Earth hinge on the magnetic field of the sun.
Anyone who lived through California’s last big drought from 2012 to 2016 remembers the rules.
You couldn’t water your yard so much that the water ran off into the street or sidewalk. Or hose down a driveway. Hotels had to put up signs telling customers they could choose not to have sheets and towels washed every day. Ornamental fountains were prohibited unless they recycled water. Watering landscaping within 48 hours of rain was forbidden. Cities couldn’t water grass on street medians. And if you washed a car with a hose, it had to have a nozzle.
The official “new normal” for the U.S. climate is warmer than ever before — and the changes are ominous for California, experts say.
The National Oceanic and Atmospheric Administration on Tuesday released its new climate averages, based on the 30-year period from 1991 to 2020. The averages, known as “climate normals,” are updated every 10 years, and they show most of the known the country, including California, heating up.
Now that Democrats have full control of Washington for the first time in a decade, Bay Area lawmakers want to make sure they don’t walk away empty-handed. For many of them, that means seeing green. After several years of historically severe wildfires, heat waves and recurring drought conditions, bills related to climate change are at the top of the agenda for many lawmakers with local ties.
The US Bureau of Reclamation last week warned water users to brace for a 500,000 acre-foot cut in water from the Colorado River as a historic drought continues to tighten its grip on the Southwest.
The cutback comes on top of a 200,000 acre-foot reduction Arizona water users agreed to last year in an effort to put off this day of reckoning. The Central Arizona Project provides more than a third of the state’s water. The reductions will mostly impact farmers.
The sparse snowpack this winter soaked into the ground during the hot, dry spring — producing little runoff.
Bonham is the director of the California Department of Fish and Wildlife.
Last month, Gov. Gavin Newsom stood on a bone-dry lakebed in Northern California and announced the state is experiencing drought conditions again. Thus far, the most severe conditions are in specific northern watersheds such as the Russian and Klamath river basins. In the San Diego region, investments in diversifying water sources, conserving and recycling have enhanced resiliency to drought conditions.
A recent report looked into why Indigenous communities within the Colorado River Basin are struggling to get clean, reliable running water.
A household in tribal lands is 19 times more likely than a white household to not have indoor plumbing, and during the pandemic this had catastrophic effects on some Indigenous communities. According a 2019 report outlining the action plan for closing the water access gap throughout the United States, “race is the strongest predictor of water and sanitation access,” and it’s Indigenous people who face this problem most.
California is once again in a drought, just four years after the last dry spell decimated ecosystems, fueled megafires and left many rural communities without well water.
Droughts are a natural part of the landscape in the American west, and the region has in many ways been shaped by its history of drought. But the climate scientist Peter Gleick argues that the droughts California is facing now are different than the ones that have historically cycled through the Golden State.
Scientists have few categories at their disposal to describe droughts, which are more complex than mere shortages of precipitation or surface water. For example, some local shortages can be invisible, as when water is transferred into a dry area from a distant source. Other shortages are chronic, with communities continuously requiring more water than is available, even in wet years. Some water shortages occur when water quality becomes so degraded that even though there may be plenty of water available, little of it is usable. With such variation in conditions, scientists need better language to conceptualize droughts.
The California State Water Resources Control Board Friday urged people and their pets to avoid the water in the Salton Sea due to a toxic algae outbreak.
Officials said that patches of toxic cyanobacteria have been discovered at numerous sites in the sea, and a dog recently died after swimming in the water.
