In the old place, you may know that we were super active on reposting #KingTides photos, and there were a lot of folks who posted there back in the day. We'd love to grow that participation here! If you're in a spot with Nov. 6 #KingTides, share your photos with the hashtag! Let's build community!

Today we're showcasing Solimar Beach in Ventura to show the possible impacts of rising sea levels, where high tides crash directly into homes with little buffer. Incidents like this show how rising sea levels can threaten coastal neighborhoods. #risingseas

#KingTides photos - spotted! The photos you take are used in many ways help people understand the impacts of climate change and sea level rise.

As sea levels rise, inland streets, such as this one in a Long Beach neighborhood, could flood more often—disrupting daily life and threatening homes.

Hi King Tides Community! We need your help to photograph the upcoming King Tides. Your photos help us understand what's vulnerable to flooding today, plan for future sea level rise, and get us all talking and thinking about the impacts of the climate crisis. What can we do to make a difference?

This bike path at Bothin Marsh was briefly submerged during last February’s King Tides, offering a glimpse of future sea level rise impacts.

The Coastal Commission’s updated Sea Level Rise Policy Guidance provides equitable, long-term solutions to keep public spaces safe and accessible for all.

Thank you to everyone who uploaded #KingTides photos! We're still working on posting them all, but you can see the results at arcg.is/0Gy5Cq. Next assignment: Have a conversation with a friend about climate change impacts on our coast and how we must take action to reduce sea level rise. 🌎🌊📷
