NCAR is a unique & valuable asset - far more than a climate model, or observations, or technology, or training ground, or gathering space. It covers weather, space weather, data, climate, paleo-climate, and everything in-between. It's building is an icon, but it's iconic status goes far beyond that.

It is hard to overstate how critical @ncar-ucar.bsky.social is to climate science in the US and around the world. It's the beating heart of our field. Generations of scientists have trained there, and almost everyone I know relies on deep collaborations with NCAR scientists. It's end is unthinkable.
Exclusive: The Trump administration is moving to dismantle the National Center for Atmospheric Research in Colorado, according to a senior White House official, taking aim at one of the world's leading climate research labs.

2025 was again a severe #hurricane season with 4 major hurricanes (3 cat 5 hurricanes).
In terms of accumulated cyclone energy (ACE) it was slightly above a normal season.
Seasonal forecasts (including ours 🥳) predicted the ACE well this year 💪
