Postfire landscapes of the 2025 Deer Creek fire, Colorado-Utah border, USA.

I wrote an op-ed on the world-class STEM research ecosystem in the United States, and how this ecosystem is now under attack on multiple fronts by the current administration: newsletter.ofthebrave.org/p/im-an-awar...

Though this is not a tree-ring fire scar, for #firescarfriday here is an interesting pic of landscape burn severity patterns from the 2025 Rabbit Creek Fire (DA-007) in the Yukon Territory.

Our new research highlights the extent that aspen stands may act as a firebreak, slowing or stopping fire. Applications for land management and implications for fire-driven conifer-to-aspen forest conversion. Thanks @grumpyunclesean.bsky.social for the summary below. doi.org/10.1002/eap....

This would be the largest public lands sell-off in modern U.S. history and it's happening with no hearings, no debate, and no public input. See what public lands would be available for sale: www.wilderness.org/articles/med...

It’s finally in writing. The detailed President’s budget clearly wants to completely eliminate USFS Research

Why do fire scars form more on the leeward or uphill sides of trees? For #firescarfriday here's a little time lapse video showing the increased residence time of flame, and thus increased heating and potential cambial injury, in the eddy of air in the lee of this long leaf pine. Florida, USA, 2025.

Hands off Gunnison Colorado! #handsoff

Flaming fire scars at the base of a longleaf pine (Pinus palustris) in the Red Hills of Florida USA. 04/02/25. Interesting how intensely these can burn once they get going. #firescarfriday

"Trump’s economic plans are incoherent and incomprehensible at least partially by design. The goal, by this longtime scam artist, is to bamboozle the American people and take their money."

TODAY IS THE DAY! 🧪☀️⬇️ Join us at the Lincoln Memorial or your local site to Stand Up for Science!

Wherever you are today, join us as we STAND UP FOR SCIENCE! For CO folks - events in Denver (1-4), as well as at noon in Boulder, Fort Collins, and Golden. Find your location info here: standupforscience2025.org/local-event-... If you can’t make an event, don’t fret—stand up loud at noon!

Faster burning fires not only burn disproportionately large areas, but they also burn more severely. Extreme fire spread events (just the top 3%) accounted for a third of the total area burned, but half of the total area burned at high severity--setting the stage for long-term forest loss. 🧪🌎🔥

To sum it up, the president ordered water released for fires in LA with water that doesn’t reach LA, at volumes that could cause communities to flood, and in the wrong season for irrigating crops, which will then mean less water for irrigating crops in the summer when it’s actually needed.

Turns out the 2010 America COMPETES Act contains language I recognize because I've cribbed it from NSF's Grant Proposal Guide for every proposal I've sent to NSF www.congress.gov/111/plaws/pu... It's encoded in 42 USC 1826p-14 uscode.house.gov/view.xhtml?r... R: the 2010 Act, L: the GPG

Who has good examples of their university leaders providing strong messaging and support for students, staff, and faculty at this time? I'd love this thread to become a space where we can provide models of how to not be a coward.

In my ongoing effort to better understand our terrible relationship with fire, and what a better one might look like, the Karuk have figured prominently. Here's my report from N. California on the inspiring things happening on their ancestral territory. www.boisestatepublicradio.org/environment/...

„The real question isn’t whether wildfires are caused by climate change, poor forestry or reckless development; it’s how climate change interacts with other factors. No disaster mitigation technique will succeed if we keep burning fossil fuels at our current rate.“ www.latimes.com/opinion/stor...

Postdoc opportunity w/Solomon Dobrowski and me! U Montana, in partnership with the NC Climate Adaptation Science Center, is hiring a talented scientist with an interest in climate connectivity and species range shifts among protected areas. $70k/year. #SpeciesOnTheMove #RangeShifts

New UCLA rapid attribution study: “Climate change may be linked to roughly a quarter of the extreme fuel moisture deficit when the fires began. The fires would still have been extreme without climate change, but probably somewhat smaller and less intense.” sustainablela.ucla.edu/2025lawildfi...

Incredibly relevant and timely research on climate whiplash, the consequences of which are unfolding in real time in the #losangeleswildfires 🔥🌎🧪

The ingredients for these infernos in the Los Angeles area — near-hurricane strength winds and mid-winter drought — foretell an emerging era of compound events that overwhelm our ability to respond. My first piece for @theguardian.com: www.theguardian.com/world/2025/j...

from me: the lies spreading across social media about the horrifying L.A. fires (which are quite similar to the conspiracies that emerged in the wake of Hurricane Helene) reveal one grim truth about our future—this is just how every coming climate disaster will play out in our info environment

Evidence of changing fire regimes. This fire-scarred ponderosa pine (Pinus ponderosa) survived past fire but was killed by the ultra-severe, 60,000-ha Las Conchas fire in 2011. Bandelier NM, USA. #firescarfriday #deadtrees

Here's a big fire scar on a big tree for #firescarfriday. Kid for scale. Giant sequoia (Sequoiadendron giganteum), California, USA.

🔥 New paper out 🔥 Seed dispersers help plants tracking climate change on mountains! Animals are dispersing plant species to higher elevations... but over half of the plants arriving at higher elevations were exotic. 🦎🐦💩🌿 @newphyt.bsky.social 🧪🍁🌐🌏 nph.onlinelibrary.wiley.com/doi/full/10....

1/n This #wildfire study holds urgent insights for communities across the Southwest (attn @coveringclimatenow.org @sejorg.bsky.social). Authors find: In Arizona and New Mexico, “contemporary fire frequency, including recent, record fire years, is still <20% of historical levels.” And yet...

New paper in #Ecosystems by Rock, Shoup et al. shows how mountain West US ecosystems are at risk as climate-driven disturbances ( #fires , #barkbeetle outbreaks, etc.) intensify, with effects on water quality and quantity. @steve-carpenter.bsky.social @springer1842.bsky.social rdcu.be/d2iV2

🧵Thread with examples of why it’s dumb to say “CO2 is only 0.04% of the atmosphere, so it can’t possibly have an effect!” It’s time to just ignore the “400ppm is too small to have an impact” meme…

Congrats, @azhar06.bsky.social on another PhD chapter being published! Fuel architecture influences interspecific variation in shoot flammability, but not as much as leaf traits @journalofecology.bsky.social @dylanschwilk.bsky.social 🧪🌎 besjournals.onlinelibrary.wiley.com/doi/10.1111/...

Important finding for impact modelers by @kornhuber.bsky.social et al.: Climatic extremes change faster/ more severely than anticipated by climate models. The consequences anticipated with impact models (based on climate model-driven forcings) might thus be conservative. www.pnas.org/doi/10.1073/...

I signed up on Bluesky to follow other scientists but I think this is who I really needed to follow. Beautiful.

Did you know there’s a site to search for starter packs of people to follow? Built by @mubashariqbal.com blueskydirectory.com/starter-pack...

Monica Turner, world-renowned landscape/forest/fire ecologist, has joined BlueSky! Check out her profile and give her a follow! 🧪🌏🔥

You know what's cool? >20 years of #remotesensing data that allows one to produce #wildfire progression, or day-of-burning, maps. Such maps have enabled some cool studies. The pub below describes a process to produce such maps. I distribute code, with no strings attached, to anyone who asks.🧪

IPCC scenarios are projections, not predictions. "The future has not been written. There is no fate but what we make for ourselves." We get to decide what the world will look like in 2100. gmd.copernicus.org/articles/13/...

Some pithy truth-telling from @climateofgavin.bsky.social here: "You shouldn’t ask scientists how to galvanize the world because clearly we don’t have a fucking clue. People haven’t got a magic set of words to keep us to 1.5C, but we have got to keep trying." www.theguardian.com/environment/...

For anyone interested in cultural burning, Indigenous knowledge, and prescribed fire, looks like you can watch this free on local PBS or their app tomorrow. #fireismedicine sandezeig.com

"every fraction of a degree matters" is true as hell. In the same way that releasing CO2 hurts people and planet, avoiding its release saves us from potential harm This isn't some saccharine 'hopeful' message: it's the hard, inarguable physical reality. www.ipcc.ch/report/ar6/w...

lots of great stuff here on Bluesky. I'd like to add this cactus.
