Description
A diagram of the global carbon cycle might give the impression that scientists know everything about this ancient, essential element and how it moves, where it is stored, and when and why it changes. However, studying the movement (or flux) of carbon is rather elusive and difficult to calculate due to matters of complexity, scale and not least, due to climate change itself.From the local scale of ‘this forest’ to the large scale of ‘the Arctic’, it is difficult to say with certainty whether one can expect a place to be a source (like exhaling) or a sink (like inhaling) in the global atmospheric carbon balance. The elusiveness of carbon fluxes creates uncertainty when attempting to calculate and model carbon and its movement.
There is, on the other hand, zero uncertainty in the scientific community that atmospheric carbon and other greenhouse gases (GHG) warm the atmosphere, and that increased GHG emissions are leading to climate change. Societies need “deep, rapid and sustained reductions” in carbon emissions to stay within safe planetary limits. This seminar will highlight ongoing PhD research at Lund University related to atmospheric carbon from different fields.
Agnieszka Rzepczynska from the Department of Biology investigates soil microbes and their role in the global “inhale and exhale” of soil carbon. Lina Lefstad from LUCSUS analyses the sustainability of Carbon Capture and Storage mechanisms and their expectations for net carbon removal. Alexandra Pongracz from the Department of Physical Geography and Ecosystem Science looks at whether vegetation models are keeping pace with rapid and complex changes occurring in the Arctic carbon cycles due to climate change.
