Our interdisciplinary team studies interactions and feedbacks between climate, carbon cycling and ecosystems in northern latitudes

  • to assess and predict changes in global carbon cycling, which is a crucial requirement to develop strategies to counter anthropogenic climate change.
  • To educate the next generation of climate scientists in the fields of biology, chemistry and geology.
  • To engage the public to implement strategies that help society and ecosystems reverse or adapt to climate and environmental changes


Our shared vision is

  • to develop and deploy cutting-edge science to understand biogeochemical cycles in a changing anthropogenic world.
  • to develop strategies to help society and ecosystems reverse or adapt to climate and environmental changes.


We want to achieve excellence through:

  • Scientific rigorousness and openness
  • Ethical practices in all areas of endeavour
  • Scientific accountability
  • Respect, professionalism and dedication
  • Sense of responsibility to transfer knowledge to the public
  • Sharing of best practices and working as a team
