I’m a climate scientist. Let me fix this headline. “Nearly a century ago, scientists showed that burning fossil fuels warms the planet. Today, we know human emissions account for over 100% of the warming. Yet dark money and disinformation still work to keep Americans addicted to fossil fuels.”

Cetacea

Very fun to see some findings from our recent study in @consletters.bsky.social being transmitted this way! I will happily back this campaign :p www.theguardian.com/commentisfre...

🧬This deer has been cooking for awhile! 🍖🦌🧑‍🍳 We generated the first nuclear palaeogenomes for the extinct giant deer Megaloceros - arguably the biggest deer ever with antlers spanning up to ~3.5 m Including one to ~50x! Check out the preprint here www.biorxiv.org/content/10.6... 🧵below

As happy as I am that the most extreme carbon emission scenario has been deemed infeasible, I am kind of sad to see it go. RCP8.5, we had some good times together modeling climate change risks for species. www.nytimes.com/2026/05/26/c...

Why did some bowhead whale populations recover from industrial whaling… while others never really did? The answer may have been hiding in Arctic sea ice all along. 🧪 #SciComm buff.ly/y05bkD6

🐋🧬 WHALE GENOMICS PAPER ALERT!!! 🧬🐋 Our new paper, co-led by @mick2474.bsky.social and myself, is now published #OpenAccess in Molecular Ecology! Our interdisciplinary approach reveals the genomic structure/diversity of #bowhead #whales across their circumpolar #Arctic range. Details below 👇 1/🐋

🐕🧬 Contributed to a new paper out in @consletters.bsky.social! Using a palaeogenomic baseline, we found domestic dog introgression is limited in free-living dingoes, and associated with human population centers and lethal control practices. 1/2

On NSF’s postdoc page, the biology and earth science fields have been completely eliminated; the only remaining fellowships are in math, astronomy, engineering, and “entrepreneurship.” Weird choice not to support research on the life support system for 8 billion people. www.nsf.gov/funding/post...

🐋🐋 ANOTHER BIG WHALE PAPER JUST GOT ACCEPTED THIS MORNING!! 🐋🐋 Keep an eye out in the coming weeks for some really cool interdisciplinary work on #whales #genetics #ecology 🐋🧬🐋🧬🐋🧬

📜New Paper📜@ecography.bsky.social Species distributions aren’t just about where species occur, but how survival, reproduction and development vary across environments. We formalise the Demographic Niche Concept to link niche theory and demography. nsojournals.onlinelibrary.wiley.com/doi/10.1002/...

The logbooks and diaries of whalers were used to reconstruct the movements of whaling ships into the heart of the Arctic Ocean in pursuit of bowhead whales. The few areas whalers couldn’t previously access are now hotspots of bowhead recovery. In PNAS: https://ow.ly/GhXA50YTkYL

Ever wondered where your back yard was millions of years ago? 🗺️ With Paleolatitude.org, you can find that out yourself! Our fully updated web tool is now live, and the accompanying paper is published in PLOS ONE (DOI: 10.1371/journal.pone.0346817).

Our commercial #bowhead #whaling paper has now also been featured in National Geographic! www.nationalgeographic.com/animals/arti...

How general are aquatic food-web responses to climate change? You can't answer that from one site. New paper proposes PondNet, scaling up the IberianPond Network to a global experiment. @mncn-csic.bsky.social @mncn-bgcg.bsky.social nsojournals.onlinelibrary.wiley.com/doi/10.1002/...

🐋🐋🐋 MASSIVE WHALE PAPER ALERT!!! 🐋🐋🐋 Our new paper "Historic logbooks reveal spatial footprints of commercial whaling" has just been published in @pnas.org! Come see how we use centuries-old #logbooks to understand population recovery patterns a century after Arctic #whaling. Details below 👇 1/🐋

3 hours ago, I shared my results of having combed through ~470 DOJ Epstein files that mention Jack Horner, his MSU email, or "Dinochicken". I posted a copy, w/ screenshots and receipts, to r/Paleontology. It has been pinned by moderators and thus far viewed 38k times. www.reddit.com/r/Paleontolo...

Our recent study in Ecological Modelling shows that southern right whale mother-calf pairs leave calving grounds once calves reach ~8 m in length, not after a fixed time. Larger, fatter mothers help calves reach departure size faster! 🐋⚡ Read it here: www.sciencedirect.com/science/arti... 🌐🌏🌱🧪

Jack Horner in the Epstein File trying to raise money to fund dinosaur research. When I discovered we had rich nazis on our dig in 2008, I dropped them like a rancid turd; ask Don. There will never be a Trumpasaurus with my name attached! @paleontologizing.bsky.social @utahpaleo-ufop.bsky.social

Our recent study in the Journal of Experimental Biology demonstrates how body size and condition reduce heat loss in southern right whales & that they do not need to migrate to warmer waters to offset heat loss in their newborn calves🐋 #marineecology #Science #marinemammalresearch #Rightwhales 🌐🌏🧪🌱

Another thought on the generative AI debate. As more and more AI slop papers come out, it becomes *more* important to actually read the papers and *more* important to gain domain expertise to spot fakes. An AI generated summary of an AI generated paper isn't going to tell you the paper is fake.

Maybe this explains the mysteries of the North Pole! 😂😂😂 🎨: @safelyendangered.bsky.social #WhaleTales

Nice to see conservation policy outcomes from simple ideas 20+ yrs ago I had access to remote areas of Kuwait/Iraq, & saw its potential as bull shark 🦈 nursery habitat Then spent 10+ years collecting evidence to back this up shorturl.at/0Cm0f Now designated an Important Shark & Ray Area

Yesterday I successfully defended my joint-PhD between the University of Copenhagen and the University of Adelaide! I am now officially Dr. Nick! And I also received favorable reviews and minor revisions on my two in-review chapters the same day! #phdone 🐋🐋

Reposting this today to give it some more attention. Working on this paper with other @palaeoverse.bsky.social folks was a great experience 😄. Hopefully this will serve as a great resource for paleontologists in the future! It even comes with R code that you can copy/paste: tenrules.palaeoverse.org

🐋 Big commercial whaling paper (and my last PhD chapter) just submitted to PNAS! 🐋

It's well known that Bowheads live to be 200+ years old but here's a bonkers thing that we didn't realize until we had Nick on the pod - that means a whale alive today could potentially have been alive before whaling started AND they lived through the decades of whaling & the century of recovery🤯

I use BHL every single day in my research and teaching. I could not write my books or articles without it, I don't know what my students would do without it, and I would have to radically rethink my career without it. This is more critical with funding cuts. Please, please someone support BHL.
