🚨Two fully funded PhD opportunities in Australia!

Improving C4 photosynthesis in vegetation models.
Supervised by Dani Way (ANU, Canberra) and myself (UTS, Sydney).

1. Lab- and field-based project at ANU – see flyer below

2. Modelling project at UTS – www.findaphd.com/phds/project...

Two PhD opportunities at the Australian National University and the University of Technology Sydney, working on thermal responses and thermal acclimation of C4 photosynthesis. www.findaphd.com/phds/project...

Vegetation biogeography is a main source of uncertainty in modelling the land carbon cycle!

✨ 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!

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...

"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.

Hydrogen emissions are ‘supercharging’ the warming impact of methane - Carbon Brief The warming impact of hydrogen has been “overlooked” in projections of climate change, authors of the latest “global hydrogen budget” say.

The Global Carbon Project has just published the most comprehensive Global Hydrogen Budget to date.

H2, although not a GHG, has an indirect Global Warming Potential 37 times more potent than CO2.

#Demography, dynamics and data: building confidence for simulating changes in the world's forests

by Eckes-Shephard et al.

@WIleyPlantSci #PlantScience

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.

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...

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.

What a pleasure to write a News & Views piece on this intriguing article that found surprising insights into WUE trends --> www.nature.com/articles/s41...

Deforestation Increases Vegetation Vulnerability to Drought Across Biomes Satellite observations show that drought impacts on biomass are more severe when forests are converted to non-forests Dynamic global vegetation models generally agree on a more negative drought s...

A post-processed carbon flux dataset for 34 eddy covariance flux sites across the Heihe River basin, China Abstract. The eddy covariance (EC) technique is currently the most widely used method for measuring carbon exchange between terrestrial ecosystems and the atmosphere at the ecosystem scale. Using this...

A gap-filled and partitioned eddy covariance flux dataset for 34 sites across Northwest China is now publicly available online. Our data paper, led by Xufeng Wang, just came out in Earth System Science Data.

Nice! Would be good to compare with our grazing implementation in LPJ-GUESS at some point (which is still in its infancy).

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 .....

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.

Greenwashing and denial won’t solve beef’s enormous climate problems I’ll admit it: I like beef. Like many Americans, I was brought up to believe that beef was a central part of a traditional family meal. My mom made it. My kids ate it. Marketing campaigns told me it w...

Beef has a climate problem. Facing it requires we look beyond greenwashing and focus on hard truths.
