This is AI2ES, my AI institute. No way around it other than to say this is really awful. We are doing so many amazing things! We want to keep doing amazing things but without this level of funding, we will not be able to do so.
Another blow to meteorological R&D this morning, as it was confirmed that NSF is terminating funding for its main weather and earth science focused AI research institute led by the Univ. of Oklahoma. Also - a LOT of weather to talk about, especially in the West. More: https://tinyurl.com/mr2znbdb

If you've heard something about Antarctica's sea ice melting but are not sure why that matters, you won't get a clearer explanation than this web story.👇

#Antarctic sea ice is:
⚙️ a global climate engine
☂️ a cooling sunshade
🌀 a pumphouse for currents
🧊 a vast verandah for life
♻️ one of the largest seasonal cycles on Earth
🌬️ highly sensitive to climate variability
🌊 What happens when there's less sea ice?

Due to the current gap in funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program is pausing most operations effective 12 May 2025. Nearly all staff will be furloughed until funds from our existing NSF grant become available. For more information, see buff.ly/d2TC1Oy

Have you ever looked at a weather map online? Or seen a nice visualization of weather forecast model output? If so, NSF Unidata almost certainly made that possible in one way or another.
Modern meteorological education would not be possible without the data, tools, and resources they provide.

The deferment has ended. Fire expert, Prof David Bowman being very direct about what the climate- change driven Californian fires mean for Australia. Our cities are just as vulnerable as LA. Canberra 2003 fires demonstrated this, but more that 20 years on, we have put more fuel on the risk of fire.
We knew this would happen eventually. We have moved from possible futures to these things now happening. The deferment has ended.
LA is on fire. How will Australia cope when bushfires hit Sydney, Melbourne or another major city?

🚨 It is now 100% certain that 2024 will be the hottest year on record and likely the hottest year in many thousands of years. With 9 days remaining in 2024, the only way to not break the record would require global cold not experienced since the Pleistocene. 🔥
