Be sure to talk to #AGU25 student poster presenters! See someone standing around at their poster, stop and ask them to give you a short overview, and ask a friendly question or two.
It's a good -- and fun & easy -- way to support professional development and skill building in the geosciences. 🧑🎓

No OSPA at this year's #AGU25, which is disappointing, because it made sure that students had at least 3 scientists come to their poster, ask questions, and provide anonymous (hopefully productive) feedback afterwards. Does anyone know why it was dropped? @hydrology-agu.bsky.social or @agu.org

Ice breaking capabilities are essential to support critical research on the Antarctic ice sheet and its response to climate change. This reversal of decades of US leadership in polar research is shortsighted and counterproductive.
What a blow to Antarctic research in the US and all of us in the international Antarctic science community that rely on the logistical and intellectual infrastructure - sending strength to colleagues affected this 🌊
The National Science Foundation will stop operating the Nathaniel B. Palmer icebreaker and slash polar science funding by 70 percent, devastating Antarctic research

Hurricane Erin achieved something most storms do not this weekend. "Extreme Rapid Intensification". Did climate change play a part? Science says, yes.
In 12 hours winds increased by ~65 mph. Only 3 other storms have done that and Erin was the earliest & only August storm to do so.
