I'm excited to share our new paper, led by @erleellis. By combining global maps of human populations and land use, we found that ~75% of terrestrial nature has been shaped by people for at least 12,000.

pnas.org/content/118/17…
Our main take-home points: 1) "With rare exceptions, current biodiversity losses are caused not by human conversion or degradation of untouched ecosystems, but rather by the appropriation, colonization, and intensification of use in lands inhabited and used by prior societies."
2) "Global land use history confirms that empowering the environmental stewardship of Indigenous peoples and local communities will be critical to conserving biodiversity across the planet."
In other words, most of the places we think of as "pristine wilderness" have been shaped by people for many millennia. Moving past the flawed thinking based on this myth is important for protecting biodiversity, and indigenous rights and sovereignty.
Thanks to @erleellis for leading, with coauthors @nick_gaut @GoldewijkKees @parnajarlpa @NicoleLBoivin @sdiazecology @dqfuller, Jed Kaplan, @naomiekingston @harveylockewild @crystalmcmic Darren Ranco, Torben Rick, Rebecca Shaw, Lucas Stephens, @JCSvenning, and James Watson.

@ClimateBen This is incredibly irresponsible and harmful. Tacking “BREAKING” onto an unattributed statement is bad enough, but you’re also misrepresenting Gavin—he never said that. You need to delete this. What you’re doing is wrong, Ben, and I think you know better.
@ClimateBen To support your first tweet, you link to two papers about impacts to support your statement, and you misrepresent and exaggerate the findings of both (neither of which Gavin was involved in). Most people won’t actually read the articles, let alone the papers you posted.
@ClimateBen The climate crisis needs no exaggeration to drive action. But threads like this make it harder and harder for scientists to debunk doomist narratives, and as a result, we’re getting attacked by people citing our own work on climate change, who accuse us of downplaying the crisis.

We're starting! Oooh, we start with a love triangle!

Three goats leave, two goats come home.

Welp, that was a super short love triangle.

Mulder is in his element. He's so excited he's got his sunflower seeds out. He can barely contain himself.

🌿It's @OurWarmRegards episode day! 🌿We talked about the power of fiction with @EricHolthaus and Kim Stanley Robinson, who each wrote recent books that provide roadmaps towards a better climate future: warmregardspodcast.com/episodes/build…
This was such a fun conversation, not only because we got to have Eric back on the show (as the founder of Warm Regards). Eric took a break from the podcast to work on The Future Earth, and it was really nice to be able to close the loop with a conversation about his book.
I also got to talk with one of my favorite authors about one of my favorite moments in one of my favorite books, and that's just not something one gets to do very often, if ever.

We hope you enjoy this first episode in our two-part finale, and we'd love to hear what you think.

I’m on the board of a non-profit, and we hired anti-racism consultants to do an assessment of our culture and practices. One thing that came up is this notion of how whiteness, as an identity, is constructed. You can’t “fix” racist structures without doing the “heart work” too.
Meaning, if you pit structural solutions (eg, “hire more Black people”), against a racist culture, the culture will always win out, and you will likely fail in your goals. The heart work — unlearning the deep programming of white supremacy—is not optional.
The kicker is, part of white identity construction involves emphasizing technical (acute) over adaptive (systemic) change. Meaning, how we are trained to approach problems in white culture? Often just exacerbates those problems. And that’s a problem if you actually want change.

Hey, while I have you here, I wanted to share two of my lab's papers that came out right around the election when everyone was a bit distracted.
The first is by my former PhD student, @DulcineaGroff. She found that the establishment of seabird colonies in the Falklands 5000 years ago triggered a big ecosystem change on land. She was able to pick up this shift thanks to (you guessed it) poop! advances.sciencemag.org/content/6/43/e…
Seabirds eat in the ocean, and nest on land, so they're a kind of sentinel of global change. Long-term records like Dr. Groff's can help us protect these birds (and their habitats) as the climate warms in the Southern Ocean.

I keep thinking about something Dr. Sacoby Wilson (@ceejhlab) sad during this episode. He talked about Ernest Boyer's five dimensions of science: discovery, teaching, integration, engagement, application. “If you’re not doing all five dimensions, you’re doing science science.”
"I’m not curious about anything I work on when it comes to environmental justice. Because it’s macabre. “I’m curious about being poisoned,” basically, that is inhumane. Unethical..." 2/n
"So when we do science that only observes an issue or science that extracts from people’s experiences and doesn’t give back, that’s (in my opinion) bad science." 3/n
