I saw someone post, apparently seriously, “we don’t need NOAA, we can just ask ChatGPT to predict where and when hurricanes will hit.” I don’t think we should sentence thousands of people to death because some overconfident buffoons don’t understand how science works. 🤷

Lots of people on my feed are concerned about the destruction of NOAA by the Trump administration and Elon Musk, but much of what I’ve seen people post about is the national weather service. That’s vital, but NOAA does so much more than that! My latest, for @ucsusa.bsky.social 🧪🌎🦑🐠

Some exciting news- for my ocean conservation and sustainable fisheries research, policy, and education efforts, I’ve been named one of the 500 most influential people shaping policy by the Washingtonian! @washingtonian.com

Could we just not with the “tech bros have a bold controversial idea, scientists are skeptical” articles anymore? Skeptical scientists are always correct in these instances. Every time. www.popularmechanics.com/science/a647...

If you’re concerned about the impact of the proposed budget on Federal funding of science but aren’t sure what to say when you call your elected officials, remember that a coalition of professional societies representing nearly 100,000 scientists signed an open letter about this a few weeks ago. 🧪
