I study old-growth forests and climate change from trees to regions and seasons to centuries. A colleague termed it RetroEcology - https://broadleafpapers.wordpress.com/ Love music in 3/4, 6/8, 5/4, 11, & other offbeat signatures (no real pun intended)
I did a paper that considered the response to the 1918 pandemic right as Covid was getting going and we...decided largely to pretend it never happened and with it and the end of the war we went "well that's it, back to normal" then everyone spent the 1920s going insane. bsky.app/profile/erik...
It continues to fuck me up that we stay thinking about 9/11 but want to memory hole Covid so bad we're destroying the entire concept of public health in the US.

From the author: "this forest gets 3500 mm of rain/yr and has no distinct dry season...initial hypothesis: these trees grow more when there is more light." "Trees were still more likely to grow under wetter conditions (low VPD ☁️ 🌡️, high soil moisture 💧)" onlinelibrary.wiley.com/doi/10.1111/...

We deployed automated point dendrometers on 35 trees representing three life history strategies in an everwet subtropical forest with 3500 mm rain annually and no pronounced dry season. Contrary to t...

It's not that climate change is "worse than expected". It just feels worse when it happens to *you*
This is disgusting and unacceptable. President Trump withheld much-needed funding for education, energy projects, healthcare, housing, and infrastructure from states that didn't vote for him in 2024. Federal funding should not be subject to political vendettas. www.nytimes.com/2026/07/24/b...
Trump Administration Admits Canceling Grants to States That Did Not Vote for Him
Federal officials said in court documents that they halted billions of dollars in funding for energy projects to states “based solely” on whether they backed President Trump in the 2024 election.

Last week's terminations at the Agency for Healthcare Research and Quality (AHRQ) total at least 150 grants worth $230M. That is over half of the agency's portfolio. It's the latest assault on healthcare, health equity, and the rule of law. grant-witness.us/posts/2026-0... #AHRQ 🧪
Termination of AHRQ grants is the latest assault on health equity and the rule of law. – Grant Witness
The agency charged with finding ways to make American health care more effective has been gutted. Last week’s terminations are just the latest blow.

Please blow up the public comment (included below): BREAKING NEWS (7/15) — The administration wants to destroy Chaco Canyon without consulting Tribal Nations. It’s an irreplaceable historic & cultural site with 4,700 archeological sites that could be lost to the bulldozers of oil & gas development

Sampled in a remarkable forest recently. Some old trees. More surprising is the combo of species: Liriodendron tulipifera alongside Betula papyrifera. The former more common in the SE US while the latter streams far into northern Canada. I’ve seen Spruce-Oak stands, never TulipPoplar-Paper Birch

For folks asking why bother commenting because the OMB won't care: comments help build cases for the courts by explicitly laying out harms. That's why it's really important to have your comments be as specific as possible. Also, contact your senators and reps! They actually do care about this.
Monday is the deadline for public comment! The Heritage Foundation has been mobilizing its members to leave comments in favor of the rule change, so every unique comment matters (don’t use a form letter or copy/paste—similar comments are batched and treated as one).
I’m looking to recruit a postdoc to join my research group at University of Iowa to work on disturbance ecology and biodiversity! Start date flexible, lots of opportunity for skill development, collaboration, and mentorship. Will review applicants in mid-August! Link: gavinmjones.com/opportunities/

Perfectly encapsulates the Trump regime approach to pretty much everything: A preposterous Bizarro World political tool designed from the start to lie and damage trust in experts and institutions and headed up by a third-tier failed Twitter troll
The White House has reconstituted the U.S. Global Change Research Program, which tracks climate change and produces the National Climate Assessment. The Trump version will focus on "positive" climate effects and be used to protect fossil fuel companies from lawsuits. www.politico.com/news/2026/07...
🌳 Tree mortality in 🇫🇷 France rose 1.5–4× (2015–2023). 500k+ trees analysed; warmer winters & springs are top drivers. Even wet springs increase mortality risk via 'structural overshoot'. Seasonal climate combos matter more than single extremes. #forests #climatechange www.nature.com/articles/s41...
I strongly urge anyone with strong sentiments on this critical issue to offer a public comment by July 13. You don't need to be a scientist; this rule change would affect everything from disaster response to cancer research--and involves your tax dollars: www.regulations.gov/...
