I've been debating for a long time whether or not to share this publicly. I'm doing it now because I believe that only by sharing the raw, personal trauma may some understand that this isn't politics—it's about the basic right to life and dignity.

Happy to have attended the @mncn-bgcg.bsky.social department gathering in El Ventorrillo! ☀️
It was inspiring to hear about the high-quality research others are doing, sparking ideas for future collaborations. I was also happy to get the chance to present my own research interests and recent work.

New data on 2023's marine heatwaves is alarming. Oceans hit unprecedented temps & durations, with some events so extreme they're considered once-in-centuries occurrences. It's a clear signal that warming climate impacts are accelerating.

Trump is stripping protections from marine protected areas – why that’s a problem for fishing’s future, and for whales, corals and other ocean life
America’s marine protected areas help fish populations thrive. Trump’s plan to open them to industrial fishing may ultimately harm the fishing industry itself.
