  • Climate change, El Niño to blame for extreme weather in California

    Scientists are saying that climate change and El Niño, a climate pattern caused by the warming of the Pacific Ocean, are the culprits for the extreme weather that California is experiencing this winter. Here's what USA Today reported:

    Multiple weather phenomena are conspiring to make these storms particularly damaging. Warm water provides energy to storms, and record-high ocean water temperatures, likely from climate change, are being detected around the world.

    Additionally, the Pacific Ocean is also seeing the effects of a more localized El Nino, where weakening trade winds reduce the upwelling of ocean waters and allow surface waters to bake in the sun and grow warmer still. And California, coming off years of drought and wildfires, is particularly vulnerable to mudslides and flooding.

    "The atmospheric river firehose is aimed at Los Angeles," tweeted Meteorologist Ryan Maue. "The onslaught has just begun from this treacherous bomb cyclone."

    What exactly is an atmospheric river anyway? The CW affiliate KTLA breaks it down:

    An atmospheric river is basically a conveyor belt of moisture from the Pacific Ocean — and while they’re not on land like typical rivers, they do contain enough water to be classified as rivers, U.S. Geological Survey explains.

    Technically, an atmospheric river is a channel of water vapor that gets picked up near Hawaii, then transported by atmospheric wind directly into the West.

    You might’ve heard the phrase, "Pineapple Express," which is another, unscientific term.

  • No days off for L.A. public schools

    "Individual school closures, if any, will be determined based on safety and on guidance provided by City and County response teams. ... Please use your best judgment based on the conditions where you live and your ability to safely travel to your school/work location."

    Remote learning will be available for students who cannot access campuses.
