Wildfire causes accelerated permafrost thaw in northern peatlands due to summer-time processes (reduced shading and soil heating) not due to winter-time processes (snow dynamics). Patience pays off - I helped instrument the site in 2014, and now completed by Stephanie Wright!

AI is Destroying the University and Learning Itself Students use AI to write papers, professors use AI to grade them, degrees become meaningless, and tech companies make fortunes. Welcome to the death of higher education.

A nice deep blue pond in a peatland. Sparse spruce trees in the background

This one is for the peatland nerds:
We are organizing a session on 💧water in peatlands 🌿 at the ASLO conference in Montreal May 12-16 2026 - join us! Deadline for abstract submission Nov 25, more info here www.aslo.org/aslo-sil-202...

@bioclimatology.bsky.social hosted a fascinating workshop on fluxes anywhere and anytime

thanks to all the old and new friends from across the German speaking parts of Europe for attending. here is a list of talks and speakers. and thanks to the Goettingen team for hosting

AI chatbots are already biasing research — we must establish guidelines for their use now The academic community has looked at how artificial-intelligence tools help researchers to write papers, but not how they distort the literature scientists choose to cite.

"Researchers are scrutinizing AI-generated sentences while implicitly enabling these systems to choose which scholars are cited ... which research directions might be promising. They are accepting the outputs even though the underlying information has been distorted."

The weak land carbon sink hypothesis Satellite-derived time series of vegetation carbon do not support a strong Northern Hemisphere net land carbon sink.

Maybe the land carbon sink is weaker than we thought. Big implications: "A lower-than-expected land carbon sink would also imply that the land biosphere may be closer to transitioning from a net carbon sink to a net source than current models predict" Randerson et al. www.science.org/doi/10.1126/...

Vertical wind profile data from a Doppler Lidar

First data coming in from our Doppler Wind Lidar at the Acadia Research Forest AmeriFlux site in New Brunswick @ameriflux.bsky.social @fluxnet.bsky.social Cool to see high-resolution vertical wind profiles over the forest

Wind lidar at an Acadian forest in NB, Canada

Finally, the Streamline VS Doppler wind lidar at the @ameriflux.bsky.social Acadia Research Forest in New Brunswick, Canada is up and running producing vertical and horizontal wind profiles! Opening new opportunities to study land-atmosphere interactions and boundary layer dynamics!

Graph with blue and red bars which represent temperature departures from the reference time period (1850-1900). the first year is 1850 and the last year (which coincides with the highest value) is 2024.

graph with blue and red dots which represent temperature departures from the reference time period (1850-1900). the first year is 1850 and the last year (which coincides with the highest value) is 2024.

2024 is almost history and the global temperature forecast for the remaining few days is rock solid now. Time to wrap up.

In most datasets, 2024 will be 0.1 degree C warmer than 2023. Also, 2024 will be the 1st individual year above the 1.5 degree Paris warming threshold in all datasets.

A figure from the Transformative change report summary by IPBES showing the underlying causes (capitalism, nature-people disconnection) of nature's decline

The message from the latest work by @ipbes.bsky.social is clear: "Previous and current approaches have failed to halt or reverse nature's decline at a global scale". We can't tackle the underlying causes of nature's decline (wealth concentration, gain prioritization) without questioning capitalism

We also run a ceilometer at the site and frequently launch radiosondes. Please DM me if you want to know more

We measure fluxes and profiles of air temperature, humidity, and wind throughout the canopy for all those interested in forest microclimates

Thanks to all the colleagues and students from Dalhousie U and from elsewhere for making this happen

Acadian forest with boundary layer clouds

This is figure 2, which shows a visualization of forecasts and tropical cyclone tracks.

A paper in Nature presents a machine learning model, called ‘GenCast,’ that can produce a reliable probabilistic weather forecast, expressed as probabilities of various outcomes, based on current and future weather. https://go.nature.com/3B8PsdD 🧪

We are looking for a postdoc to join our group at @gfz.bsky.social in Potsdam, Germany to work on drones, GHG, and peatland restoration. Apply until Jan 5th! And come talk to me @agu24.bsky.social if you’re interested! @fluxnetecn.bsky.social

The 1.5°C Target for Global Warming Must Prevail | by Joeri Rogelj - Project Syndicate Joeri Rogelj argues that the threshold established by the Paris agreement remains crucial – even if it is breached.

Climate action is falling terribly short
Time to bury the 1.5C goal?

Absolutely not - why the 1.5 goal must prevail
(even when global warming exceeds 1.5C)
