Drought and heat stress play a crucial role in global carbon and water cycling, and these impacts are largely mediated through terrestrial vegetation. However, many uncertainties remain regarding the consequences of drought and heat stress for vegetation physiology, their ramifications for carbon-water cycling across scales, and the degree to which we can accurately quantify these stressors using remote sensing and models. Recent methodological innovations and the harmonization of vast networks of ecosystem data have set the stage for a holistic understanding of how the terrestrial biosphere responds to, and feeds back upon, drought and heat stress.

This session focuses on the impacts of drought and heat stress for terrestrial vegetation, from individual plants to the biosphere. This includes approaches such as plant ecophysiology, ecosystem carbon-water cycling, remote sensing, and process-based or statistical modeling. Research that touches on multiple spatial or temporal scales, or utilizes numerous methodologies, is highly encouraged.
