Excited to share our new paper led by Tsinghua Uni ECR Zhang Han: www.science.org/doi/10.1126/.... New model based on eco-evolutionary optimality explains observed seasonal and spatial trends in stem respiration, implies stem CO2 efflux down by >25% by 2100, reducing land carbon emissions.
Thermal acclimation of stem respiration implies a weaker carbon-climate feedback
The efflux of carbon dioxide (CO2) from woody stems, a proxy for stem respiration, is a critical carbon flux from ecosystems to the atmosphere, which increases with temperature on short timescales. Ho...

How does photosynthesis respond to changing temperatures?
In the paper led by Pascal Schneider, we show that the thermal acclimation of photosynthesis can be modelled without making assumptions about plant functional types - ready for adoption in ESMs

US grass-fed beef is as carbon intensive as industrial beef, even after correcting for soil sequestration from rangeland grazing. Operational emissions of grass-fed beef are 3–43 times higher than pork, poultry, cheese, milk, or plants. In PNAS: www.pnas.org/doi/10.1073/...

Terrestrial carbon sinks have increased by 30% over the last decade, with most carbon stored in soil and water rather than forests, highlighting the need to reassess carbon distribution models. doi.org/g887dg
Not just trees: Most of the carbon sequestered on land is stored in soil and water, study finds
Recent studies have shown that carbon stocks in terrestrial ecosystems are increasing, mitigating around 30% of the CO2 emissions linked to human activities.
