What is the cost of wildfire, windthrow and bark beetles for Europe’s forestry? We estimate that disturbances reduce Europe’s forest value by €115 bn, more than doubling to €247 bn under severe climate change. Led by @johannesmohr.bsky.social, out in @natclimate.nature.com doi.org/10.1038/s415...

Climate change increasingly alters the interactions between forest disturbances. Here we present a framework for quantifying dist. interactions and compile evidence for their impacts.

"Years with such extreme FWI metrics are 88-152% more likely across global forested lands under a contemporary (2011–2040) climate compared to a quasi-preindustrial (1851–1900) climate, with the most pronounced increased risk in temperate and Amazonian forests." www.nature.com/articles/s41...

New paleofire study! Spring droughts have intensified over the past 250 years, reshaping fire seasonality in eastern Canada. Spring is now nearly as flammable as summer, driving infrequent but large and severe fires 🌲🔥 onlinelibrary.wiley.com/doi/10.1111/...

Here is some early Sentinel-2 footage (May 26, 2025) of the 25LF-SHOE wildfire near Prince Albert National Park (Saskatchewan). This fire has since become the largest active fire of the 2025 season in Canada, with over 550,000 hectares burned as of today, June 17, 2025.

I'm a bit late on this, but here is Sentinel-2 footage (June 6, 2025) of the G90216 fire in northern British Columbia. The western front is over 50 km long, and the entire fire is still out of control, with ~211,000 hectares burned.

Zabaikalsky Krai is a rural federal region, with < 1.5 million people in an area a little smaller than Sweden. This is a transition zone from the steppe grasslands in the south to southern extent of the boreal forest in the north. These are likely fires set to cover up illegal logging. #Wildfires

Natural disturbances are often invoked as an argument against creating new forest reserves. But are reserves more affected by disturbances than managed forests? For C Europe the answer is no, in fact reserves have lower disturbance rate & severity than managed forests! doi.org/10.1111/1365...

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 ...

LA is in a high fire risk region & fire weather conditions are complex. So we @wwattribution.bsky.social looked at many lines of evidence. All show: our burning of fossil fuels increased the likelihood of such extreme fire weather conditions www.worldweatherattribution.org/climate-chan...

🚨NEW SCIENTIFIC STUDY🚨 8 million tonnes of CO2 ~ 2% of french greenhouse gas emissions 🔵⚪🔴 ~ 30% of the national sequestration capacity of the forest🌳 That's the carbon emissions from fires in 2022! 🔥 ⚠️Predominant effect of soil combustion 🧵👇

Even more important, fast fires are more destructive with climate change. Fire size has never been the primary issue, it's all about how fast these fires grow, as illustrated in our recent paper led by @earthlabcu.bsky.social Director Jennifer Balch in Science (www.science.org/doi/10.1126/...)

No, “brush clearance” could not have “prevented” the Palisades Fire, but fuel reduction would reduce the firestorm’s intensity. And as @amycardinal.bsky.social put it so well, “it’s not only about wildfire risk reduction, but living daily in healthy landscapes that are properly stewarded.”

Good introduction to prescribed fire associations. www.nytimes.com/2024/11/24/o...

“It’s not just a California quirk,” Pyne said. “California, I think, gets there first in exaggerated forms, but this is a national issue. And, in fact, it’s becoming an international issue.”

Here's the reality about the #LAFires this week: this isn't the first time ANY of these places have burned. Not even close. In 2018, we mapped CA fire history to look at fire frequency across SoCal. Santa Monica Mtns area burns more than anywhere else -- up to once per decade in a given spot. 🧵

In 2024, wildfires burned a record number of forests participating in California's forest offset program, exposing the danger of relying on forests to slow climate change. onlinelibrary.wiley.com/doi/10.1111/...

There's a new paper on the effectiveness of protected areas which illustrates alot of what I find troubling in discourses about conservation policy effectiveness, as well as global analyses.

How #forest #fires also have an impact on #lakes theconversation.com/how-forest-f...

Also, to make our matter worse: while storms have historically been responsible for most of the overall losses, they are slowly being taken over by wildfires (i.e., extra CO2e release).

How does the form of stand replacing disturbances vary across the world? @n-acil.bsky.social has mapped them out in this very nice paper from her PhD work www.nature.com/articles/s41...

Interesting - in some parts of the world, it is common for many fires to ignite and be extinguished before there an overpass from a satellite that would detect them! Leaves a lot missing from global fire analyses using satellite detections 🤯 Underscores the importance of regional collaborations!!🔥🛰️
