Terrestrial Carbon Dynamics under Climate Change - From ecosystem processes to global carbon budgets
This presentation is the first of four talks by internationally recognised ecosystem and Earth system scientists working at the interface of field observations, Earth observation, and modelling to understand terrestrial carbon dynamics under climate change.
The four talks together explore how terrestrial ecosystems regulate greenhouse gas fluxes under climate change, from local processes to global budgets. They combine high‑resolution measurements from peatlands and wetlands, ecosystem and Earth system modelling, Earth observation, and biodiversity research to examine how hydrology, temperature, vegetation, and functional diversity shape carbon dynamics, ecosystem resilience, and our ability to quantify and project the global carbon cycle.
Welcome to listen to the first presentation by Professor Mana Gharun!
Drivers of northern peatland CO2 fluxes revisited: interacting water level-temperature dependency
Pristine peatlands act as natural carbon sinks, but disturbance — mostly anthropogenic drainage — turns them into CO2 sources, responsible for 2–5% of annual greenhouse gas emissions globally. Complex interactions between vegetation, soil, climate, and hydrology produce highly variable CO2 budgets on different types of peatlands and between years. This talk is about a synthesis of high resolution gas flux measurements across northern peatlands and the new patterns emerge if we consider the interacting effect of fluctuating temperature and groundwater level on CO2 fluxes.
