California’s El Niño Winter: Coastal Flooding, Debris Flows, and What to Do

The ocean is already running a foot above the tide tables, three hurricanes’ worth of surf has torn up the Southern California coast, and NOAA now favors a wet winter from San Diego to the Oregon line. How to prepare for El Niño in California: king tide dates, atmospheric rivers, burn scar debris flows, and what to do this week, this month, and this fall.

30-Day Flood Insurance Rule: Buy Before the Storm

Your homeowners policy does not cover flooding. The separate policy that does has a 30-day waiting period, and the NFIP’s authorization runs out December 11, right as the El Niño storm track sets up across the southern U.S. What Florida’s insurance meltdown teaches the rest of us, what a flood policy covers, and what to do this week.

Stacked bar chart of U.S. personal carbon footprints by income group in 2019: poorest 10% 7.3 tons, lower income 11.6, middle class 18.2, upper income 37, top 1% 198. The share from investments rises from 2% for the poorest to 68% for the top 1%.

Low(er) Impact Living

Reduce, reuse, recycle… but who’s actually doing it? Here’s how big the average American footprint really is, why the top 1% leave a much bigger mark, and the habits I use to live lighter, ranked from free to $$$$. No guilt, just values in action.

USGS Updates Burn Scar Flood Model

A quarter inch of rain in fifteen minutes can turn a freshly burned slope into a river of mud and boulders. The warning system has long leaned on a model built from Southern California canyons, then applied to the entire West. A new USGS update refits it for three regions and beats the old version by roughly 15 to 60 percent, with fewer false alarms. A strong El Niño is on the way, so read this before the next storm.

What’s Hot in Climate Change – Fall 2026

This Fall’s What’s Hot in Climate Change roundup highlights five notable climate-related stories, ranging from the brewing “Godzilla” El Niño, mountains storing water, bad climate tipping points, good climate tipping points, and the importance of dialogue and community action.
