We just had to share this impressive imagery of severe thunderstorms sweeping across Texas yesterday, captured by @NOAA's #GOESEast (#GOES19) 🛰️. The visible imagery reveals fine details within the storms, while the satellite’s Geostationary Lightning Mapper highlights where lightning flashes occurred.

Science matters. Here's a few headlines & stories that caught our attention this week. A flooded future for cities like New Orleans & T-Rex's tiny arms. We're thinking of doing more shorts like this, so if you like it, please let us know and pass it on. youtube.com/shorts/tQm0Aoeu0…

A lot of us will be outdoors a lot this Memorial Day Weekend, so remember: Thunderstorms can produce deadly lightning strikes up to 10 miles away. When Thunder Roars, Go Indoors! weather.gov/safety/lightning

A freight train of warm water chugging beneath the surface of the Pacific Ocean is a big reason why a super El Niño may form this year. Ocean waters have peaked around 7.5˚C (13.5˚F) above average, breaking records. And now, it's nearing the western shores of South America 🧵

46 years ago Mount St. Helen's erupted. It was the worst volcanic disaster recorded in US History. It was a tragic disaster but also a watershed moment for our understanding of volcanoes, the need for monitoring and more. Here's bit more in this short. youtube.com/shorts/8-r9mn5li…

For the first time, undersea gliders are in the 2026 National Hurricane Operations Plan & the IOOS Association is recognized as they prepare to deploy gliders to improve hurricane intensity forecasting. Check out this cool short video on why it matters. youtube.com/shorts/79Q_2gZvv…

No one should have been hiking on this active volcano! Indonesian disaster agency gave warnings. Science, communication, and messaging are all important but people need to make smarter choices especially guides. Such deaths and injuries are preventable. cnn.com/2026/05/08/asia/indo…

The heat is on in subsurface equatorial waters, suggesting strong El Nino on the way. Could devastate Galapagos wildlife (land and ocean). El Nino's shut down upwelling, reduce food availability for marine iguanas, sea lion pups, birds, penguins & more. Corals also at risk.

Excellent piece about second highest #tsunami on record in Alaska fjord 2025, link to climate change, & increased risks to #cruise ships & tourists in the region. Based on Science article led by Daniel Shugar, Univ Calgary (DOI: 10.1126/science.aec3187). eos.org/articles/the-forensi…

Kīlauea Eruption Episode 46 Update May 5, 2026, 5:30 pm HST 
 
Episode 46 of lava fountaining in Halemaʻumaʻu at the summit of Kīlauea began at 8:17 am HST on May 5 and ended about 9 hours later at 5:22 pm HST. 
 
With the reduced ground and aviation hazards due to the lava fountaining episode ending, the USGS is dropping the Volcano Alert Level from WATCH to ADVISORY and the Aviation Color Code from ORANGE to YELLOW. 
 
We’ll share more details about this eruptive episode in our next post. 
 
Kīlauea has been erupting episodically since December 23, 2024, from two vents (north and south) in Halema‘uma‘u, in Hawai’i Volcanoes National Park. Lava fountaining episodes, which generally last for less than 12 hours, are separated by pauses that can be longer than three weeks. 
 
🎥 Video of episode 46 on May 5, 2026.
