I study forests and fire 🔥. Thus, climate too. Professor at Western Colorado University.

Our new paper asks the question: is there any precedent for recent, high-severity fires that have removed >100,000 acres of forests from northern New Mexico? Based on the locations of trees that recorded surface fires over the prior 500 years, the answer is, statistically speaking, "not a chance".

1/5 New paper in PNAS led by Andreas Wion! 🔥🌍🧪 For centuries, dry-conifer forests in the western U.S. burned frequently, but mostly at low severity, meaning most trees were not killed by fire. Read on for details ...

Wildfires are getting so large and severe and summers so hot and dry that some forests just aren’t growing back after burning. Recent research suggests up to 40% of Western conifer forests could transition to grassland and shrubland by 2100, taking significant carbon storage with them.

Wildfires Are Turning Forests in the American West Into Shrubland (Gift Article)

Towering woodlands in the West are being permanently replaced by tracts of spiky shrubs. Conditions “just aren’t normal anymore,” one researcher said.

A great illustration from NM today of how recent wildfire burn scars can contain new fires. This is why you want a mosaic of burn scars (prescribed and wildfire) on the landscape. So any new fire gets boxed in by the old ones.

Some nice media exposure on our new paper published in @globalchangebio.bsky.social pertaining to expanding area burned by high severity wildfire. 🌍🔥 Thank you, @murphywoodhouse.bsky.social, for raising awareness about this important paper. Tagging bsky co-author @coopecology.bsky.social.

Took me forever, but finally got my spot on @grumpyunclesean.bsky.social's latest paper up. Worth a read if you care about fire. www.boisestatepublicradio.org/environment/...

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.

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. 🧪🌎🔥

1/n Our team just published a new paper in Global Change Biology 🧪🔥 The title succinctly describes the main take home message, but here's the deal: We produced gridded, fine-scale (resolution = 30m) daily fire progression maps for 623 wildfires in the SW US using satellite fire data. read on ...

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.

"This is the wrong time of year to be releasing water from reservoirs...This is going to hurt farmers," Vink said. “This takes water out of their summer irrigation portfolio.” www.latimes.com/environment/...

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.
