As sea levels rise, moments like this may become more common and limit access to nature, especially for people with mobility issues.

Plus, we will collect photos on Nov 6 and Dec 6, 2025 in Southern CA and some Northern CA locations.

10 tips for bringing climate change solutions into the classroom I joined Teach For America right out of undergraduate and taught 8th-12th grade science at North Central High School in South Louisiana.

A lot of educators ask us how they can incorporate ideas about climate change in the classroom.

Here are some great ideas from Dr. Elizabeth Bagley, our Managing Director at Project Drawdown @projectdrawdown.bsky.social

Line graph time series of 2025's daily global sea ice extent in red shading compared to each year from 1979 to 2024 using shades of purple to white for each line for between the months of January and April. The year 2023 is also highlighted in yellow, which was the current absolute record low previously. There is substantial interannual and daily variability.

A closer look at the extent of sea ice globally that just set a new all-time record minimum, which is due to unusually low sea ice conditions in both the #Arctic & #Antarctic right now.

Is climate talk off-limits over the holidays? The most important thing you can do to fight climate change + practical tips to help you start today

Skipping climate conversations during the holidays may seem safer—but think again. Talking about climate change doesn’t have to be overwhelming or divisive. I’m convinced it really is possible to navigate these convos in a way that brings people together, not pushes them apart. Here's how! ⬇️

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. 🌎🌊📷

King Salmon is a unique fishing community lined with canals on Humboldt Bay. This past weekend, a surge of seawater propelled by a powerful storm system, southerly winds and a king tide pushed into Avishai Leibson’s seaside falafel hut, bringing nearly a foot of water into the restaurant.
