Currently in Los Angeles — September 18, 2023: Ridiculously resilient marine layer

The weather, currently.

Haven’t seen a marine layer this robust in September in LA ever. After brunch on Saturday, with a marine layer of 3,000 ft, and still no signs of sun, I made the executive decision to get outta dodge. It wasn’t until I reached Ontario in the San Gabriel Valley that the marine layer gave way to hazy sunshine. And in Palm Springs at 6p, it was sunny and 91.

To start the work week, expect similar unseasonably dreary weather across southland, with the coasts and even valleys all entrenched in a marine layer pattern courtesy of an upper level low sitting off the California coast. Even if a particular region does clear by the afternoon, temperatures will be in the upper 70s at best. Yikes.

The State of California filed a lawsuit on Friday against the five largest oil companies and their lobbyists, alleging that they deliberately misled the public to protect their profits — putting lives at risk and worsening extreme weather, creating billions of dollars of damage in the process.

"Oil and gas companies have privately known the truth for decades — that the burning of fossil fuels leads to climate change — but have fed us lies and mistruths to further their record-breaking profits at the expense of our environment. Enough is enough," said Rob Bonta, California's attorney general.

The lawsuit pits the largest US economy against the heart of the global fossil fuel system — and is analogous to the recent successful lawsuits against utility companies in California for their role in sparking deadly wildfires. This time, California is demanding the oil companies pay their share of damages to the state for their decades of lies.

Meanwhile, on Sunday, in the largest climate march since Covid, more than 75,000 people rallied in NYC explicitly to end the era of fossil fuels. The demands were clear: President Biden must declare a climate emergency and take immediate action to wind down fossil fuel production and use throughout the economy. And that work needs to be done with climate justice at its center.

Here’s AOC’s full speech at Sunday’s global climate march to end fossil fuels in NYC:

It’s happening, y’all.
