🌊 Coronado’s beaches are disappearing. They’re currently losing about 4 feet of sand every year due to sea level rise, king tides, and storms.
Without action, experts estimate that up to 70% of California’s sandy beaches could vanish by 2100. Locally, Stan’s Beach faces some of the greatest erosion risks.

While beach replenishment projects add millions of cubic yards of sand, the solution is temporary. Long-term resilience comes from restoring native sand dunes, which help trap sand, reduce erosion, and protect communities from storm surges.

Want to learn more and get involved? Join the free Saving Stan’s Beach community forum tonight, June 17, from 5:30–7:00 PM in the Nautilus Room at the Coronado Community Center. Residents and experts will discuss shoreline preservation, dune restoration, and ways the community can help protect Coronado’s coastline.

🏖️ Protecting our beaches means protecting our environment, economy, and coastal way of life.

Those white streaks behind airplanes aren’t just clouds… they’re contrails, and they may have a bigger climate impact than aviation emissions themselves. Formed when jet exhaust freezes at high altitudes, contrails trap heat in the atmosphere, especially overnight.

The good news? Small altitude adjustments and smarter flight routing can dramatically reduce them. Combined with sustainable aviation fuels, the aviation industry could cut its climate impact by up to 50%. Cleaner skies mean a healthier planet for all of us. 🌎✈️

Now found from coast to coast, this highly adaptable songbird is native to the western U.S and Mexico. House finches, which gather in flocks, are the most abundant bird in the region. 🐦

Appearance: Females and young house finches have plain brown faces and blurry stripes over pale underparts, while male house finches have red eyebrows and foreheads contrasting with brown caps.

Sound: Male house finches sing a jumbled warbling song composed of short notes. The song often ends with an upward or downward slur and lasts about 3 seconds. Females usually have a shorter, simpler version of the song. (Click here to listen to their songs and calls.)

Diet: Finches feed their young exclusively regurgitated plant matter, a fairly rare occurrence in the bird world. House finches flock to backyard bird feeders, favoring sunflower seeds, thistle, and native berries. If you have a bird feeder, these are likely your most frequent customers.

Climate threat: Spring heat waves endanger young birds in the nest. 🐦

⚽🌎 The FIFA World Cup 2026 kicks off on June 11 and will be the largest tournament in history, featuring 48 teams, 104 matches, and 16 host cities across the U.S. (including San Diego!), Canada, and Mexico. While FIFA has pledged to make this its most sustainable World Cup yet, experts note that increased travel and the expanded format could make it the most carbon-intensive tournament to date.

Positive initiatives include:

• Using existing stadiums instead of building new ones
• Diverting waste through recycling, composting, reuse, and donation
• Reducing single-use plastics with recyclable and compostable alternatives
• Reusable cup programs at select stadiums
• Heat-mitigation measures such as shade, misting stations, and climate-controlled venues

As fans from around the world come together to celebrate the beautiful game, small actions like using public transit, carpooling, and reducing waste can help make a difference. 🌱🏆
