Trump administration orders dismantling of the U.S. Forest Service Late Tuesday afternoon, with the subtlety of a wrecking ball and the morality of a foreclosure notice, the Trump administration announced the most devastating attack on the U.S. Forest Service in the ...

Amidst everything else, the Trump regime has quietly killed off the U.S. Forest Service 🌲

“One hundred and ninety-three million acres of your national forests… just handed, on a silver platter, to the people who’ve spent their entire careers trying to destroy it.”

#AGU25 folks, there is a rapid- response town hall TODAY on the #NCAR dismantling at 1 pm, La Nouvelle Orleans ballroom C (per an AGU media advisory)

Save NCAR from being dismantled today! The Trump Administration has vowed to dissolve the center that provides critical extreme weather and climate data for our nation.

I wrote to my representatives @hirono.senate.gov @schatz.bsky.social, and Ed Case to tell them to stop the dismantlement of NCAR. You can do the same with your representatives at this link.

NCAR is quite literally our global mothership.

Everyone who works in climate and weather has passed through its doors and benefited from its incredible resources.

Dismantling NCAR is like taking a sledgehammer to the keystone holding up our scientific understanding of the planet.

Unbelievable.

Three books by W. Bond and collaborators: Fire and plants (1996), Fire in Mediterranean ecosystems (2012), and Open ecosystems (2019).

I'm very sad to say William Bond, of the University of Cape Town & Fellow of the Royal Society (@royalsociety.org ), has passed away. It is a great loss. He was an enthusiastic ecologist and a critical thinker. I learned a lot, and I still had a lot to learn from him. RIP. 😢

Making a climate model that works well is really, really hard. So hard, in fact, that the people who do make it happen rarely have the time or energy to talk about how hard it is on the internet. So most other people have very little understanding about how hard it is... But boy is it hard #NorESM3

Extremely large fires shape fire severity patterns across the diverse forests of British Columbia, Canada Warming and drying conditions are driving increases in wildfire size and annual area burned across the forests of British Columbia, Canada. The impact of increasing fire activity on these forests rem...

Important new paper by Luke Collins and colleagues: "Extremely large fires shape fire severity patterns across the diverse forests of British Columbia [BC], Canada"

Key findings:
1. Fires in BC have increased in size from 1986-2021
2. Bigger fires have larger patches of high-severity fire

The PhUnFETTy lab will have four presentations at #ESA2025. These will cover plant ecophysiology, trait ecology, eutrophication, water availability, mycorrhizae, demography, theory, modeling, and more!

Check out the flyer and replies below for more details. Hope to see you in Baltimore!

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!

If you are doing wildfire-relevant research, especially with the goals to understand the complex climate, vegetation, soil, fire, and human interactions in the Earth system, please consider submitting abstracts to our #AGU #fire session:

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.

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....
