Exclusive: NSF stops awarding new grants and funding existing ones US science funder also plans to screen grant applications for compliance with ‘agency priorities’.

And so it continues (and by “it” I don’t mean US scientific greatness)

The U.S. has two tsunami warning centers, both operated by NOAA. Employees were terminated from these centers today. The Pacific Tsunami Warning Center covers Hawaiʻi, and now it is less safe to be near the beach.

Climate change in the polar regions of our warming world is threatening to transform many of its features, such as this icy tableau in the Fish Islands off the coast of the Antarctic Peninsula. There is still much to learn about these places before we know better what those changes may be.

Climate change in the polar regions of our warming world is threatening to transform many of its features, such as this icy tableau in the Fish Islands off the coast of the Antarctic Peninsula. There is still much to learn about these places before we know better what those changes may be.

A new special issue of Science highlights research on Earth’s frozen places—from the Arctic to the Antarctic—and how it’s changing due to climate change and the geopolitical challenges this important work faces.

🌊 The 2022 collapse of the Conger–Glenzer ice shelf in East #Antarctica shows that ice-shelf loss due to warming is committed long before it actually happens.
