Begging the @portofsandiego.org to give us safe bike facilities on Harbor Island. We don't need a dangerous 4 lane highway to nowhere on scenic Island with no accommodations for people trying to enjoy the coast outside of a car.

Join our race against the Rapid 215 Bus by bike! The 215 is the highest ridership bus line in San Diego and it is so slow that a bike is faster.

It is important to validate InSAR time series results! And to call it out when people oversell the capabilities of the method! (Ideally before Science magazine airs out your dirty laundry in public...)

It's not often you can describe a scientific article as an absolute banger, but I'm revisiting again the paper on ESM-snowMIP by Menard et al 2021 and it really is an absolute banger. Completely genius paper. I am amazed such a candid article got through review.. journals.ametsoc.org/view/journal...

Very convenient data, esp. if you otherwise have none. We tested the data extensively vs terrestrial water budgets and even against data from the @esaearth.esa.int CCI sea level budget. I might give it a try also as GRACE 'gap filler'

More info on #NoKings San Diego transit stats since I couldn't load this 300 page PDF on my phone yesterday. The last two protests before yesterday had about 30,000 extra trips over an entire normal Saturday, all within a couple hours.
Screenshot of a powerpoint slide. The bottom has a red banner and logo for San Diego MTS. The title is "No Kings Protest October 18, 2025". The bullet points say "Enhanced Service on Blue & Green Lines", "Regular Saturday Ridership averages 95,000", "125,000 Passengers (30,000 difference)", and "largest Saturday Crowd Since Comic-Con 2024". There are four images captured from CCTV cameras showing large shoulder-to-shoulder crowds on train platforms and light rail vehicles enter and exit the station.

A rare 4-car train operating on the San Diego MTS Green Line to handle post- #NoKings crowds. Four-car consists are typically reserved for major sports events. According to MTS Board meeting presentations, they carried an extra 30,000 passengers (15,000 round trips) during the last No Kings protest.

Promachus hinei, a robber fly. These are indeed flies, but they are quite the predator. I have seen them take down dragonflies much larger than itself. But besides what they do, they are just beautiful creatures.

Red-legged Honeycreepers. Honduras. They are a type of tanager. They feed on flowers and fruits, and like hummingbirds, they have a long tongue for probing into flowers. The vivid blue color is not from pigments but is a structural color, where nanostructures in the feathers scatter blue light.

Home. Ocean Beach, San Diego, California #SanDiego #sunset #OceanBeach
Ocean Beach Pier stretches diagonally across the frame at sunset, its dark silhouette supported by evenly spaced pylons above rolling waves. The sky glows with a band of orange and red along the horizon that fades into deep blue overhead, with long streaks of cloud spreading across the scene. Wet sand in the foreground reflects the fiery colors of the sunset and the shadowed shape of the pier, creating a mirror-like strip of warm light against the darker water.

The 3/10/1933 Long Beach quake killed 120 people and brought home the dangers from unreinforced masonry buildings. It led to the first seismic provisions in the building code and the passage of the Field Act that ensured strong seismic safety measures for public schools.

Wide view of a wooden pier extending from the left toward the center of the frame at dusk. Dark blue sky fades to a narrow band of orange light at the horizon. Small pier lights form a dotted line along the structure. Gentle waves blur across wet sand in the foreground, reflecting the pier and the warm horizon glow.

Ubehebe crater. A phreatomagmatic eruption, where magmas impinge upon wet sediment or groundwater causing rapid vaporization. Volume expansion during vaporization causes the water saturated overburden (roof) to explode. Sudden depressurization causes magma to then erupt catastrophically.
