A new paper in @nature.com led by Jeff Chambers, finds evidence of climatic mortality thresholds combining heat and drought, & explores the emergence of 'hypertropical' climates in future climates. Amazing multi-decadal effort by the field teams involved 👏

An excellent first day at the Royal Society event on 'Marine biodiversity loss, fishing and climate change', including this inspiring talk from Camille Parmesan. Always interesting to compare terrestrial and marine ecosystems. Looking forward to more talks tomorrow!

Can we really count on land to deliver climate mitigation?

Our new highlight unpacks what AR/BECCS can do — and where uncertainties bite (carbon stocks, permanence, local climate effects).

Just published, a land-mark paper by Annemarie Eckes-Shephard et al.! It assesses the performance of a new generation of Demography-enabled Dynamic Global Vegetation (D-DGVMs), that attempt to simulate the changing size and age structure of trees in forests.

Simulated and observed annual mature forest turnover time and woody biomass increment flux at a boreal, temperate and tropical site.

Demography, dynamics and data: building confidence for simulating changes in the world's forests Vegetation demographic models (VDMs) are advanced tools for simulating forest responses to climate and land-use changes, and are essential for projecting carbon cycling and large-scale forest manage.....

Our paper is now published! A inter-model evaluation at a variety of forest biomes of nine "state of the art" demographic vegetation models. Well done @annemarie-es.bsky.social and @tompugh.bsky.social for leading this endeavour!

Great to visit CEFAS yesterday with Helen Powley to talk about our work on two-way coupling ERSEM-mizer: impacts on mesozooplankton, carbon cycling and interactions with benthic fauna as part of EU projects NECCTON and @oceanicu.bsky.social

New conversation article by my @plymouthmarine.bsky.social colleague May Rodriguez (who isn't on here yet)

From mapping forest function and disturbances, exploring forest dynamics to mortality from drought, 2024 has seen several analyses we've been working on for years finally come out. Here's a quick summary of them, @julenastigarraga.bsky.social @n-acil.bsky.social @daijunliu.bsky.social

Great range of PhDs on offer through the NERC GW4+ DLTP (www.nercgw4plus.ac.uk/apply), including this one in my group exploring how Europe's forests respond to extreme droughts: www.findaphd.com/phds/project...

Lots of flexibility with questions and methods, so get in touch if interested! 🌳🍃💍🛰️📉

🚨 PhD: "Forests on the edge: examining vegetation recovery following climate extremes" at @bristolbiosci.bsky.social with myself, Lina Mercado (Exeter) and Eddy Robertson (UK Met Office). I would REALLY love to find a student for this, please share widely (thanks)

Probably not, I was just copying it from my tag.

This is a great effort by Doug Kelley from CEH that employs a novel bayesian approach to analysis how different variables (temperature, wind speed, population density, etc.) corresponds to satellite pan-tropical tree cover.

There's lots of nuance over different regions and ecosystems.

Fire, environmental and anthropogenic controls on pantropical tree cover - Communications Earth & Environment Fire has less direct influence on tropical savanna tree cover than previously believed, while heat stress, water availability, wind throw and changes in fire regime are more critical, according to sim...

First post on bsky, very happy that our paper on "Fire, environmental and anthropogenic controls on pantropical tree cover" is now out in Communications Earth & Environment.

📢Global Carbon Budget 2024📢

Despite some predicting a peak in global fossil CO2 emissions, we estimate growth of 0.8% [-0.3% to 1.9%] in 2024. Maybe a peak next year?

Is it all bad news, or can we find some good news?
