Humboldt Waterkeeper

a purple background, with three white stars stacked vertically and numbered 1-3. Text reads "Dark sky friendly lighting has...1) brightness <1,000 lumens 2) warm color tempearture: 2,700 K or less 3) fully shielded and directed downwards...our migratory birds appreciate your Dark Sky friendly lights!" bottom shows two fully shielded lights (where the lightbulb is completely covered by the housing) and a red and orange hummingbird

a purple background with white text that reads "What does warm light mean? How "warm" or "cool" a light source appears is described by Correlated Color Tempearture (CCT), aka color temperature, measured in kelvins (K). Lower CCTs are "warmer" in appearance, while higher CCTs are "cooler" in appearance., 3 squares with progressively more saturated yellows and black text reading: 3000 K warm white, like tungsten-halogen lamps, 2700 K warm white, like 100W incandescent lamps (this one has a white circle around it, pointing to text underneatht hat says "best for migratory birds"), 2600 K warm white, like 60W incandescent lamps. bottom has 4 migratory birds-marbeld godwit, wilson's warbler, varied thrush, and snowy plover

background: a starry sky seen between two rocky cliffs, between which lies the ocean. text reads: Migratory Birds Travel at Night... ...to use stars for navigation, avoid predators, fly in calmer air, avoid overheating, and to have opportunities to refuel during the day. For example: Snowy Plovers, Marbled Godwits, hummingbirds, vireos, and buntings. At the bottom is 4 pictures of birds: snowy plover, marbeld godwit, varied thrush, wilson's warbler. top right has a red and orange hummingbird.

background: a starry sky seen between two rocky cliffs, between which lies the ocean. text reads: Light pollution disrupts our circadian rhythm...Studies have shown the level and duration of darkness we experience before sleep is more important than the amount of time spent in bed. Melatonin, the hormone that helps you sleep, can be suppressed by exposure to blue light. Artificial light at night has been found to contribute to certain cancers, heart disease, diabetes, obesity, mood disorders, and insomnia. (International Dark Sky Discovery Center, 2025)

Humboldt County's new Outdoor Lighting Ordinance has many people asking, “How can I protect the night sky?”

The Coastal Act is the People's Law, and always has been. It was established by ballot measure - it protects our beaches and coastline for the People of California.

The Right to Clean Water Act has passed its first legislative committee! THANK YOU to Senate Environmental Quality Committee Members for voting to #ProtectCAWater & ensure a clean water future for all Californians! @senatorblakespear @senatorstevepadilla @sencarolinemenjivar @senatorsrp @senatorgo

If you surf, wade, kayak, swim, fish, or paddleboard in Little River, Humboldt Bay, or Mad River Estuary, tell the Water Board not to delist these streams without considering the best available scientific information. Comments are due by NOON on Wed. April 2. See link for more info.

US judge rejects SpaceX lawsuit claiming anti-Musk bias Elon Musk’s SpaceX has failed to establish it was a victim of political bias by a California agency that voted to reject expanding its rocket launches in the state, a federal judge ruled.

We're not surprised that this frivolous lawsuit was thrown out, but that's because we know a thing or two about how the California Coastal Commission reviews federal projects.

Proposed California water law would revive Clean Water Act rules Supporters of SB 601 say the bill is a response to a 2023 ruling by the U.S. Supreme Court and to a second Trump administration.

"Because it doesn’t create new rules, SB 601 isn’t expected to add costs or red tape for the farmers and ranchers, water agencies, builders and manufacturers most often affected by clean water laws." #RightToCleanWaterAct @cawaterkeepers.bsky.social

California bill would restore wetlands protections in wake of Supreme Court ruling A Supreme Court ruling placed limits on federal protections for many streams and wetlands. A bill in California’s Legislature seeks to restore safeguards.

We can no longer rely upon the federal government to protect and provide clean and affordable water. That's why we are sponsoring the Right to Clean Water Act to reestablish the safeguards that have been stripped from California's waters. Read more in the LA Times: lat.ms/3FDW6KI. #ProtectCAWater
