Kathe Todd-Brown#TreeMortality is often neglected in #EarthSystemModels. Global veg models are often very satellite driven leading to detailed #photosynthesis models (dependent on in solar radiation, temperature, and moisture) but less detailed tree death (often just proportional to biomass).
Yu etal 2022 ( https://www.nature.com/articles/s41467-022-29619-4 ) used #MachineLearning to better estimate tree mortality. => Generally reduced expected #LandCarbonStocks.
Field-based tree mortality constraint reduces estimates of model-projected forest carbon sinks - Nature Communications
Here the authors use broad-scale tree mortality data to estimate biomass loss, constraining uncertainty of projected forest net primary productivity in 6 models, finding weaker tropical forest carbon sinks with climate change.
