Lapsed geologist, Chief Scientist at @oceana.bsky.social, dog mom. DC born and raised. Philly is my 2nd home.🖖

Skeets my own, *not* my employer’s. Mostly oceans + science + climate + policy. A little politics (sorry) and Phillies (not sorry).

Time to get your public comments in on the proposed Waters of the U.S. rule that would strip protections for countless wetlands and streams.

Countries meeting in Brazil for two weeks could manage ONLY a VOLUNTARY agreement to BEGIN discussions on a roadmap to an EVENTUAL phase-out of fossil fuels, and they achieved this INCREMENTAL progress only in the teeth of IMPLACABLE OPPOSITION from OIL-PRODUCING countries.

Nearly 30 countries refuse to sign a final #COP30 agreement that doesn't include "fossil fuel phase-out," as negotiations head into overtime.

An image of two activists wearing long trains reading "end the fossil fuel era" and "phase out fossil fuels" with banners above them reading "stop Amazon oil" and "1.5oC under threat: time to act."

Very cool - but also a reminder that this is a relatively fast growing coral and they still don't do much in a year. And why it's so hard to regrow/replace damaged reefs in a time frame that matters to humans.

I had no idea these critters existed

Man, crabs just evolve into all kinds of places

Have you ever seen the granulate shellback crab? Unlike hermit crabs—which hide inside their chosen shells—this unusual-looking crustacean uses its posterior legs to hold a shell onto its back, protecting it from foes.

A photo of a granulate shellback crab held in a human hand. The crab is hair, with a flat face, "hairy" body, and small legs. It is in a mollusk shell.

Ocean plastic kills sea creatures. For the first time, researchers set out to find out how much it takes. The answer: Surprisingly little.

the nazis and pro-nazi media blamed all the ills of german society on jewish people. it was how they primed the pump before the holocaust. if u dehumanize people and say they cause all the problems, it becomes easy to exterminate them.

the right is doing the same thing to immigrants.

A great thread on the new IEA report, which seems to suggest (promote?) the idea that we need/want to burn more fossil fuels. Quite the pivot from their last few reports. #greensky #energy #climate
stephenleahy.bsky.social Stephen Leahy @stephenleahy.bsky.social · 12d
FT reports on US blackmail:

"Chris Wright, the US energy secretary, told Bloomberg that the IEA’s modelling of peak fossil fuels was “total nonsense”, that he was in contact with Birol and that the US would either reform the IEA or withdraw its support"

Did you know that every piece of tuna you eat is regulated under an international treaty?

There are super wonky and hardworking folks out there trying to make sure short sighted decisions and/or inaction don’t tank the fisheries.

I love Weddell seals so much I will pick up their poop and put it in a small vial just so I can get a chance to be near them and watch them hanging out on the ice.

Thank you, BFFP, for not being too mad about losing Von! This is a great piece. He has been and continues to be a fantastic leader - whether working on plastics globally or on all things oceans in the #Philippines. We are so lucky to have him at @oceanaph.bsky.social!
