The land carbon cycle, and its fate in a warming world is clearly one of the big "known unknowns" in our climate future. It is particularly crucial to know what happens to the land carbon budget after we achieve net zero. All that carbon we have stocked so far is very vulnerable, being present

Our new paper in Nature Geoscience reveals a substantial slowdown in the rate of increase in gross primary production (GPP) in drylands, due to water constraints, but a sustained increase in humid regions in response to rising temperature and CO2. Led by Fei Li. www.nature.com/articles/s41...

Dryland dominance in the slowdown of global vegetation carbon uptake - Nature Geoscience

Machine learning upscaling analyses of global FLUXNET carbon and water flux measurements indicate that dryland vegetation productivity showed a negligible increase between 1982–2000 and 2001–2022, whe...
