Led by Adam Hanbury-Brown, we found that Sierra Nevada dry conifer forests will become carbon sources and shift to oak-dominated forests under 2.5 °C warming by the late 21st century, regardless of management. Uncertainty remains due to limited data for constraining key model parameters is.gd/dm9aPu

We are collecting records of fire behaviour in the UK!

Do you have fire behaviour observations (recent or historical) for a specific location, date and time? We welcome you to fill in this survey to help us to validate and improve FireInSite fire behaviour predictions.

Climate change has increased the odds of extreme regional forest fire years globally - Nature Communications The authors show that extreme fire years in global forests align with rare fire weather extremes. Climate change has made such extremes 88-152% more probable. These findings highlight the need for act...

This week I participated in a workshop and was struck by the difference between younger male collegues who were speaking up like they were used to being listened to, and younger female collegues who were timid and not used to being listened to. Damn, are we still here…

Another new paper published today using ECOSTRESS again to predict wildfire—this time burn severity—one week before occurrence across New Mexico. This paper also outlines a framework for using machine learning with these data and applications.

Like I've said before, if you have any doubts about climate change, just go to a super-boring insurance conference and listen to the super-boring panels where they dryly talk about the growing threat of disasters so catastrophic and unpredictable in scope they simply cannot be insured at any price.

The effect of fire on the carbon fluxes and productivity of Brazilian woodland savannas The effects of altered fire regimes within open ecosystems are poorly understood and can have serious consequences on functioning and conservation acr…

My first PhD paper is now published in #STOTEN! We used a long-term fire experiment and ecosystem monitoring protocol to quantify the effect of burning on the productivity, respiration and ecosystem #carbon balance of Cerrado #savanna (1/6)

Impacts of leaf traits on vegetation optical properties in Earth system modeling - Nature Communications Earth system models often categorize plants to just a few functional types, and plant characteristics are defined per type, neglecting their diversity. The authors show how the use of plant traits can...

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 ...

A line graph showing atmospheric CO2 levels at Mauna Loa Observatory from 1955 to 2025. The y-axis represents CO2 mole fraction in parts per million (ppm), ranging from 320 to 420 ppm, while the x-axis is years.

The most iconic figure in the environmental sciences is the Keeling Curve, the CO₂ record from Mauna Loa, Hawaii.

@noaa.gov had a wonderful site where you could visualize and download these data, and now it's just gone. These data belong to us and we should not let this happen!

January 2025 was quite unexpectedly the warmest January on record at 1.75C above preindustrial, beating the prior record set in 2024.

This is despite the presence of La Niña conditions in the tropical Pacific, with the El Niño event of 2023/2024 long faded. www.theclimatebrink....

California annual grass phenology and allometry influence ecosystem dynamics and fire regime in a vegetation demography model Grass-dominated ecosystems cover wide areas of the land surface yet have received far less attention from the Earth System Model (ESM) community. This limits model projections of ecosystem dynamics ...

Our @newphyt.bsky.social paper with @ckoven.bsky.social and others used a dynamic vegetation model to understand how grass allometry and phenology influence annual grassland matter and energy exchange and their seasonality, as well wildfire dynamics: nph.onlinelibrary.wiley.com/doi/10.1111/....

A sign that reads, “Without BART, we'd have to plant a new San Francisco sized forest every 2 years to offset the extra CO2”, but the 2 in CO2 is up high instead of down low.

I mean, I very much appreciate what you are trying to do here BART, but
