I can’t fight the eel-ing that this is the best investment you can make this holiday season.

Line graph time series of 2025's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with purple for the 1980s, blue for the 1990s, green for the 2000s, and white for the 2010s. Thin white lines are also shown for each year from 2000 to 2024. 2025 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between July and October by looking at the decadal average line positions.

Monday ice update - #Arctic sea ice extent is currently the 12th lowest on record (JAXA data) 🧪

• about 130,000 km² above the 2010s mean
• about 960,000 km² below the 2000s mean
• about 2,080,000 km² below the 1990s mean
• about 2,780,000 km² below the 1980s mean

Unmasking the Sea Star Killer After a decade of carnage, we finally know what’s devastating sea stars along North America’s West Coast. Does that mean scientists can save them?

A phenomenal scientific discovery with deveststing implications. We’ve known that vibrio would be a climate change winner for more than two decades. An uncertain future for 🌻⭐️

Heartbreaking scenes from the #GrandCanyon filled with smoke from the #DragonBravo wildfires. A testament to the science and support needed to maintain resilient natural systems.

Thanks for responding! Hopefully they resolve the issue soon.

I had plans to visit next week, I’m absolutely heartbroken by this turn of events. So much history and so many habitats destroyed.

Also, a bummer to be charged a $10 camping cancellation fee to a campground closed by fire.
