Broken parking meter in front of defunct 101 Ash-City Hall such a “now” problem in San Diego.

I am dizzy from the amount of info on this San Diego Community Power flyer. I would have hated to be in that meeting…how do we explain ourselves on a 4x11? HOW?

Environment Report: Why San Diego Community Power Is Stockpiling Cash The region’s government-run electricity buyer has over half a billion in its rainy-day fund but hasn’t used any of it to lower rates. Here’s why.

One of CA's biggest government-run electricity-buying orgs stockpiled over half a billion dollars in customer cash, but hasn't used it to lower rates. They raised rates this year. They blame an obligation to pay off SDG&E's contracts: voiceofsandiego.org/2026/02/02/e... @voiceofsandiego

With a nudge from industry, Congress takes aim at California recycling laws A bill in Congress seeks to eliminate different state recycling requirements and labeling by creating a single, national standard that would be voluntary.

A Republican congressman from Texas has introduced legislation to stop California from helping people understand which products are actually recyclable: www.latimes.com/environment/... via @susrust.bsky.social

Environment Report: Flood Scares Won’t Quit in Shelltown At 2 a.m. Monday morning, the De la Mora’s were outside in the rain cleaning a city storm drain with a rake.

The rain woke Brenda de La Mora at 2 a.m. She roused her husband to grab a rake and tend the storm drain near the flooding creek. Two years ago, the creek consumed hundreds of homes. So far, nothing's changed except that neighbors are triggered. voiceofsandiego.org/2026/01/05/e...

Unseasonably warm December sets temperature records as Colorado snowpack remains poor Across Colorado, this past December was among the hottest ever recorded. Both Denver and Grand Junction recorded their second-hottest December on record, according to the National Weather Service.…

Things look bad for the Colorado River, San Diego's main water lifeline. The river's source water, the Rocky Mountain snowpack, is at record lows. Colorado had its second warmest December since 1893.

I just asked Scott Cameron, Trump’s top water boss at Bureau of Reclamation, why the federal government hasn’t done anything except set new deadlines which seem to be meaningless. He wouldn’t answer my question. #CRWUA2025 @crwua_2025

Trump’s acting head of the Bureau of Reclamation warns Colorado River negotiators against suing each other: “Only certainty around litigation is a bunch of water lawyers will be able to put their children through grad school.” #CRWUA2025

I spent a lot of time getting to know hydrogen sulfide, a dramatic gas which has caused near-planetary destruction but may also cure erectile dysfunction.

South Bay Has a Gas Problem A year's worth of data shows South Bay residents are constantly exposed to low levels of hydrogen sulfide gas from the polluted Tijuana River that could harm their health in the long run.

Toxic gas data from the Tijuana River shows the amount of hydrogen sulfide won’t kill anyone instantly, for which H2S is most famous.

But there’s enough of the gas consistently circulating in South Bay that people’s health could be impacted longterm.

Arizona will use taxpayer dollars to pay private companies to build desalination plants in California or Mexico. AZ would trade that investment for more supplies from the Colorado River.
