1/1 The GCP-Global Carbon Budget 2025 has just been published in its final form. It is the same data we released at the last COP in Nov 2025, but given the many improvements this budget introduced compared to previous editions, it underwent a longer and more detailed peer review process.

Abstract. Accurate assessment of anthropogenic carbon dioxide (CO2) emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere in a changing climate is critical to bette...

✨ PhD opportunity studying drought and heatwave effects on threatened plants ✨🔥 Funded by an ARC DECRA awarded to the amazing Dr Ilaíne Matos and co-supervised by Dr Sami Rifai and me! Limited by the character limit here, so please see the attached flyer for all the details - please share widely!

PhD Opportunity in Plant Ecophysiology – Adelaide University
We are looking for an PhD candidate to join an exciting research project focused on understanding heat and drought combined impacts on threatened plants’ mortality.
Key Objectives:
Describe drought sensitivity in juvenile and mature individuals of threatened plant species.
Disentangle the effects of elevated temperature, soil dryness, and atmospheric water demand on the sensitivity of threatened species to hotter droughts.
Model threatened species’ risk of mortality under current and future hotter droughts.
Eligibility:
Australians and international applicants with a completed Master's degree (GPA > 5.0) and/or a completed 4-year Bachelor with Honours (GPA > 5.0) in Plant Biology or related areas;
Proof of English proficiency (e.g. IELTS score > 6.5 or equivalent qualification), only for applicants who speak English as a second language.
Strong analytical and programming skills in R or  Python.
Genuine interest in studying plants with previous experience in plant ecology and/or physiology.
Effective writing skills; a passion for reading, writing, and continually improving as a communicator.
Ability to drive in Australia is desirable but not essential.
Start Date: April 2026 (negotiable)
Duration: 3.5 years
Benefits: PhD scholarship (tax-exempt stipend of $36,500 AUD p.a. + $3,000 AUD p.a. top up);
Higher stipend rate for Aboriginal and Torres Strait Islander candidates ($ 53,608 p.a.);
Relocation allowances for both domestic and international candidates;
Single Overseas Student Health cover for international applicants.
100% tuition fee waiver.
How to Apply:
Email the following documents to ilaine.matos@adelaide.edu.au before the 15th of February 2026. Women and people underrepresented in research are encouraged to apply. 
1-page cover letter explaining why you are interested in this position and your previous experiences relevant for this opportunity.
Curriculum Vitae in the Adelaide University format.

"Bond’s work leaves behind an inconvenient lesson for an era of climate urgency: that speed is not a substitute for understanding, and that good intentions, applied without care, can erase ancient worlds as efficiently as neglect." A beautiful tribute to William Bond. Forever missed by many.

William Bond, defender of grasslands

In recent years, one of the loudest ideas in environmental policy has been that trees are the planet’s universal remedy. Plant enough of them, in enough places, and carbon will be soaked up, water wil...

Limited carbon sequestration potential from global ecosystem restoration - our paper was born of collective frustration around continual conflation of restoration + reforestation, invariably misrepresenting open ecosystems in global models of ecosystem C storage potential.

Limited carbon sequestration potential from global ecosystem restoration - Nature Geoscience

The maximum carbon sequestration potential from global terrestrial ecosystem restoration efforts until 2100 is 96.9 Gt, which is equivalent to 3.7–12.0% of anthropogenic emissions until then, accordin...

Some physiological processes that can be neglected when measuring gas exchange in happy plants become important when dealing with stressed plants. In this paper we outline the things that might cause trouble under suboptimal conditions. Shout out to the new journal @plantecophys.bsky.social !

Excited to share our paper with Anna Gardner and @florianabusch.bsky.social in Plant Ecophysiology!🌿 We review challenges in interpreting plant stress responses using gas exchange data, offer solutions to improve accuracy and discuss gaps in our current knowledge. www.sciltp.com/journals/Pla...

Detailed representation of H2O gas exchange (left) and CO2 gas exchange (right) at the adaxial (upper) and abaxial (lower) leaf surfaces in an amphistomatous leaf. This panel illustrates the separate gas exchange processes for each leaf surface, which can be measured individually if the upper and lower cuvettes are analysed separately—though this setup is not common in commercial gas exchange systems. Stomatal, cuticle, and boundary layer resistances are depicted for both surfaces, along with the mole fractions of water vapour and CO2.
