The Coming California Megastorm: Part 2

Back in August of last year, I posted about couple of articles describing what could happen if California got hit by a mega storm similar to the one that flooded large parts of the state in 1862  Now the excellent Eye on the Storm blog has published a three-part series that goes into much more detail about the likelihood of such as storm reoccurring and what it would mean for California and the United States. They make for some sobering reading.

  • The other ‘big one’: How a megaflood could swamp California’s Central Valley. "A repeat of the state’s Great Flood of 1861-62 could cause over $1 trillion in damage."
  • If a megaflood strikes California, these dams might be at risk. "The state’s highest-risk dams protect millions of people and tens of billions in property, including Disneyland and the Naval Weapons Station Seal Beach."
  • Climate change is increasing the risk of a California megaflood. "A 2022 study says climate change has already doubled the risk of a California megaflood. And an additional 1°C of global warming would double the odds again."

  • Another article recently published looks at the effects of this winter's series of storms.
