Climatic change and feedbacks

Climate change impacts high latitudes more rapidly and significantly than any other region of the earth. A warmer climate has already led to reduced snow cover and a longer growing season. These changes, in turn, influence the atmospheric circulation and the hydrological cycle, constituting climate feedback loops.

Understanding biogeochemical and biogeophysical climate feedbacks are a part of CBA, in particular in the LATICE Strategic Research Initiative which aims to advance the knowledge base concerning land-atmosphere interactions and their role in controlling climate variability and climate change at high northern latitudes through:

  • Improving parameterizations of processes in earth system models controlling the interactions and feedbacks between the land (snow, ice, permafrost, soil and vegetation) and the atmosphere at high latitudes, including the boreal, alpine and arctic zone.
  • Assessing the influence of climate and land cover changes on water and energy fluxes.
  • Integrating remote earth observations with in-situ data and suitable models to allow studies of finer-scale processes governing land-atmosphere interactions.
