I am pleased to announce that we are inviting applications for a Lead Laboratory Coordinator at the University of Arizona’s Laboratory of Tree-Ring Research. Review of applications will begin on September 15, 2026. For details and to apply, visit arizona.csod.com/ux/ats/caree...

I asked Claude to find all English words that end in "tionation" and it couldn't find any. I bet my isotope geochemist friends wouldn't be happy with this 😆

Ooof... this paper on AI use in academic writing, based on submissions to the journal Organization Science. Sadly agrees with my anecdotal observations as an editor. AI-tinged submissions have increased, and readability and quality have decreased. pubsonline.informs.org/doi/full/10....

So, they have a "scheduled maintenance" after a cyber attack that affected thousands of institutions. "Scheduled maintenance".

Another check in on spring's arrival for plants blooming. Timing is way ahead of schedule, with off-the-charts early activity across parts of the central and western U.S. Quite a season! Map from @usa-npn.bsky.social: bsky.app/profile/zack... Future projections: doi.org/10.1007/s003...

For a rainy day Has global warming accelerated? Why? How much? How do we know? What does it all mean? etc. With hand-drawn illustrations, dodgy metaphors, and a complete lack of clear answers. diagrammonkey.wordpress.com/2026/03/07/f...

For a rainy day

Each month, you put a little aside in a savings account. It’s not always the same amount because – you know – life is life, but each month a little gets squirreled away. Then you …

ChatGPT says 3.9 < 3.11 and then goes on to explain why that is the case by showing that 3.11 < 3.9. Logic or just strings of seemingly logical words?

I think financial incentives are important but it doesn't have to be paying the reviewer directly. For example, society journals can reward reviewers with free membership or free conference registration. Journals can also pay the reviewers' institutions...

Reading articles like this, it occurs to me that the more we try to fix problems caused by replacing social norms and relationships with financial incentives, by replacing social norms and relationships with financial incentives, the worse things will get. theconversation.com/the-peer-rev...

It was great to see Dr. Katharine Hayhoe's talk on campus yesterday (@katharinehayhoe.com). She raised the message of hope, which is much needed in our time. Thank you.

As a tree ring scientist, I routinely fix dating problems, if you know what I mean.

It's so difficult to enter a different field. With today's rejection, I've tried 4 climate history and 4 archaeology proposals, all with excellent historians/archaeologists, but all unsuccessful. These discouraging experiences are telling me to stick to safe, single-field projects. But I'm stubborn.

Update: not funded. So the dream was bad omen :(

Last night I had a dream that my NSF proposal was funded. Then I woke up realizing it was a dream. But I grabbed my phone and logged in to research.gov to check anyway. And yep, still pending... Maybe I'm thinking about this stuff way too much.

Last semester I taught a tree ring class, and I also partnered with the local forest preserve to do research & outreach. So putting 2 and 2 together, I took my class to a preserve site for field trip. It was a gorgeous fall day and we had so much fun! esec.illinois.edu/news/2025-12...

Geology can take many forms, from the study of rocks and minerals to the living records preserved in trees.

A student of mine asked our group to summarize #AGU25 in one word. For me it's HUGS. This year was tough for us scientists, and for some of us it was extremely tough. So it felt good to meet old friends and hugged it out.

Tube carriers, gather!

The Tube Carriers Every winter The tube carriers Gather Hustle through airports To stand in front of a board And talk about what they love. #agu24

If you will be at AGU next week check out the following presentations from my lab group and UNR Geography. Thursday, Heather Haines will present PP43D-1233 Arid zone dendrochronology of the widespread and ecologically critical Mulga tree 1/4

Here's the lineup of my group's presentations at #AGU25. Come meet with us!

Crowd sourcing from the Bluesky hive mind: what are these patches with what look like ducts inside that I'm seeing on silver maple? They don't occur in every ring, rather sporadically. @yellowbuckeye.bsky.social @l-tulipifera.bsky.social #dendro

I am teaching a course on ancient trees and tree rings at the NY Botanical Garden on Sunday, October 26th and Sunday, November 2nd. We will learn about past environments, the amazing lives of trees, and what old trees tend to look like. Sign up at this link: www.enrole.com/nybg/jsp/ses...

Can you hear the dendrochronologists in their natural habitat? 🧪 #dendro

Put my #rstats skills to good use today: I helped my student fix their code that took 3 minutes to process 1 month of data but now only takes 110 milliseconds to process 1 year of data. I'm happy with little things like that :)
