Ancient bristlecone pines have been collecting data for us for millennia. Scientists like Long Now Research Fellow Anne Heggli (@driscience.bsky.social) work to build a long-term scientific legacy among these ancient trees. longnow.org/ideas/long-s...

Obscure hot take: Having POSIXct and POSIXlt is overkill. POSIXlt should be deprecated.

🧵New paper out in Remote Sensing of Environment led by Katie Orndahl and Logan Berner! In this study, we (really they) mapped aboveground plant biomass and woody plant dominance across the entire Arctic tundra biome—at 30 m resolution. A thread 👇 www.sciencedirect.com/science/arti...

We are hiring a visiting assistant prof next year for freshwater sci and climate. Great dept! Spread the word. hr.wwu.edu/careers-facu...

We have a new paper now online in the Annual Review of Earth and Planetary Sciences with a group of amazing ECR coauthors reviewing methods and applications of (offline) paleoclimate data assimilation and looking toward the future www.annualreviews.org/content/jour...

Paleo poster session in lieu of class final. Here the beringia productivity paradox. So proud.

Interesting paper. Neat blend of chironomid data with a variety of dendro proxies. journals.sagepub.com/doi/full/10....

Paleo folks know @xkcd.com temperature timeline, yeah? xkcd.com/1732/ I have a 12' version printed and once per year the students are always amazed (me too).

To the student whose class eval read in it’s entirety, “🔥 🔥 Fr fr on god no cap,” I salute you.

1/n Please see our new paper in Nature Communications! We used 1,851 tree-ring fire-scar sites and contemporary fire perimeters to quantify the prevalence of wildfire from 1600-1880 compared to 1984-2022. 🧪🌍🔥 Our key findings are as follows ...

In landscape ecology, I emphasize how simple models can illustrate complex patterns—like how dispersal on an environmental gradient can look like species sorting and niche partitioning. So, I make toy models for class.

Classic reading from Wally can be a balm for hard times.

As a climate scientist in private industry, one of my jobs is to write plain-language notes on physical perils that affect the insurers and businesses. If you're curious about those products, our group just published its latest review of natural catastrophes for 2024: www.wtwco.com/en-ie/insigh...

We are hiring a TT env toxicologist in my department. Research area is broadly defined. Please pass the word: hr.wwu.edu/careers-facu...

Teaching landscape ecol! We are looking pattern/process and how v simple models -- e.g., dispersal mediated by an env gradient can produce species sorting and heterogeneity in ways that look kinda like nature. Initial random start w/ strong neighborhood dispersal and opposite mortality funcs.

Honored to write a commentary recent Pederson et al paper with an AMAZING floating tree-ring chron from whitebark melting out of the ice. The way they use that (unique) resource with ESMs is so well done and gives us a look at the mid Holocene. Freq response y'all! www.pnas.org/doi/10.1073/...

You can see the history of the landscape everywhere: An oak that probably grew in a pasture with scattered trees, likely savanna before that, now surrounded by younger trees. Within sight of our house, which sits close to the edge of open prairie on the 1830s public land survey sketch map.

Blame view in GitHub is judgy AF. I have enough emotional baggage with you GH.

this is really exciting and I look forward to learning about the science coming out of these new ice-core records in the coming years @millionyearice.bsky.social 🧊🧪 www.bbc.com/news/article...

I always go back to Richard Alley’s control knob talk at AGU. youtu.be/RffPSrRpq_g?...

Happy perihelion to all who celebrate.

As resorts and snow sport enthusiasts gear up for winter’s #snowfall, DRI's Dan McEvoy is preparing to figure out just how much snow the slopes will see this season. Read the full @usatoday.com article on their website: bit.ly/1000inchesof... #DiscoverDRI

Are you interested in understanding the links between climate change, vegetation, and wildfires? Would you enjoy working with computers? I am hiring paid interns and graduate students: jedokaplan.github.io/opportunities/ Look forward to hearing from you!

Ouch. "I would ask if you’re interested in being a student researcher, but I don’t know how to hire or pay you, and our department’s administrative associate has been doing the work of three people since the recent budget cuts." www.mcsweeneys.net/articles/cla...

Betteridge's law of headlines applies: Was there a 4.2 ka BP event in Sweden? www.tandfonline.com/doi/pdf/10.1... Interesting that this was served up to me today along with the Asian speleothems paper. 4.2 kya is dead, long live 4.2 kya. agupubs.onlinelibrary.wiley.com/doi/full/10....

Hey #dendros. Left the other place several years back and feel disconnected from the paleoecology and paleoclimate community. Hoping to get back into learning what kind of cool stuff is coming out with dendro, climate, and env data sci. And dogs. Always dogs.
