Work Package 4

High latitude processes and feedbacks

Leader: Lund University (Prof Torben Christensen)

The overall objecting of WP4 is an improved understanding of the impacts of climate variability on high northern latitude greenhouse gases (GHG) emissions through data analysis and Earth system modelling (ESM) development and application. Specific objectives are:

  1. An improved understanding of connections between marine climate and terrestrial processes in the Arctic and their implications for the atmosphere.
  2. Assessment of the large-scale sensitivity of CH4 emissions at high latitudes to interannual climate variability.
  3. Model development, model experiments, and subsequent analysis of the potential future responses of carbon and vegetation in the Arctic to a changing climate.
  4. Improved understanding of the relationships between precipitation changes and CH4 emissions at high latitudes.

Science Projects:

4.1 - High latitude ocean-land interactions

4.2 - Regional variations in atmospheric trace gas sources at high latitudes

4.3 - Land surface-atmosphere feedback mechanisms in high-latitude permafrost areas

4.4 - Stability and resilience of permafrost carbon
