Hong "California has one of the largest snowpacks on record," Karla Nemeth, director of the state's Department of Water Resources, said in a statement.    "As this snowpack melts in the coming months, the waterways will be especially cold, fast and running higher than normal," she added.      The Department of Water Resources, alongside other state agencies, are urging Californians to remain aware of fluctuating stream levels and cold-water dangers as they venture outdoors this spring.      The series of atmospheric rivers that battered the state this winter "is causing rising river and stream flow levels not seen in years," the agencies warned.      California's statewide average snow water equivalent — the amount of water contained in snow — has surged to 61.1 inches, or 237 percent of the average for early April, according to state water officials.    In the history of California's snow measurements, only 1952, 1969 and 1983 recorded statewide results that exceeded 200 percent of the April 1 average, the agency stated.      Because the snowmelt will result in "fast flows" and frigid water temperatures, officials recommended that Californians wait to enjoy time in streams and rivers until the summer.      "Rising water levels in rivers and streams will be very cold, very fast and can easily overwhelm those that aren't prepared or don't heed warnings," CAL FIRE Chief Joe Tyler stated.   The extent and expanse of this year's snowpack will pose a particularly severe flood threat to certain parts of the state, including the San Joaquin Valley, according to the Department of Water Resources.     Storms this year have already flooded many communities across the state, leading President Biden to issue a disaster declaration for several counties on Monday.   This past weekend, a teenager drowned along the American River in Sacramento County — the fourth such tragedy in the region that week, Nexstar station KTXL reported.   "Unless you are a professional Olympic type swimmer, that river can overpower you," Sacramento Metro Fire Capt. Chris Vestal told KTXL.     California State Parks Director Armando Quintero stressed the importance of adhering to public safety protocols and refraining from entering waterways if requested to do so.      "As the temperature rises, snowmelt-fed waterways can quickly induce incapacitating cold-water shock to even the strongest swimmers," Quintero added.   Welcome to The Hill's Sustainability newsletter, I'm Sharon Udasin — every week we follow the latest moves in the growing battle over sustainability in the U.S. and around the world.

The participants ranged from 40 to 65 years old.  The participants answered questions and gave blood samples in the summer of 2020, following the first lockdown.  They did the same in the spring of 2021, right after COVID-19 vaccinations began.  All participants received one or two doses of the main vaccines offered in Spain at the time: AstraZeneca, Pfizer or Moderna.   Effects on spike proteins: The researchers then measured the responses of three antibodies to five viral antigens — three of which are located on the spike protein contained in the vaccine.     They estimated exposure to fine particulate matter, black carbon, nitrogen dioxide and ozone for participants based on their addresses prior to the pandemic.     Short- and long-term immune impacts: The authors found that pre-pandemic exposure to the first three pollutants in uninfected individuals was associated with a 5 to 10 percent reduction in vaccine-induced spike antibodies. They observed a decrease in antibodies for both IgM — an indicator of short-term immunity — and IgG, which demonstrates longer-term resilience.   However, the researchers identified an inverse association for IgG, another antibody, with respect to ozone exposure.    Persistent pollution problems: "Air pollution can induce chronic inflammation, which has been associated with a negative effect on vaccine efficacy," co-senior author Carlota Dobaño, said in a statement.    "Our findings are consistent with evidence that persistent organic pollutants reduce vaccine responses in children," Dobaño added.  On Our Radar  Upcoming news themes and events we're watching: The California Department of Water Resources will hold a Tribal Water Summit Film Festival on Wednesday, April 12, in Sacramento.
