MSc Programme in Nature Management
Introduction to the fundamental physical and bio-geo-chemical mechanisms defining the climate and climate variations on Earth.
- Introduction to the fundamental processes in the climate system.
- Energy balance considerations.
- The physics of the greenhouse (atmospheric) effect.
- The concepts of radiative forcing, feedback and climate sensitivity.
- Different types of forcing: Direct and indirect solar forcing, long wave forcing (i.e. greenhouse gases), the direct and indirect forcing related to aerosols and atmospheric chemistry.
- The most important fast feedbacks (water vapour, snow-albedo, lapse rate, high cloud, low cloud).
- Climate drivers or feedbacks? A discussion of forcing versus longer term feedbacks involving the ocean circulation and the ice sheets.
- The role of oceanic and terrestrial carbon cycles (feedbacks and/or forcing).
- An overview of the role of the cryosphere in climate feedbacks.
- The processes behind so-called tipping elements.
After having completed the course the student should have an overview of the physical and bio-geo-chemical mechanisms behind climate variations/changes on Earth. More specifically the student should be able to
Knowledge
- Understand the nature of the globally averaged energy-flows.
- Understand the nature and role of the greenhouse effect.
- Account for the concepts of radiative forcing, climate feedbacks and climate sensitivity and be able to perform simple exercises involving these concepts.
- List the most important climate drivers and feedback mechanisms operating on different time scales and to separate climate drivers from climate feedbacks.
Skills
- Apply the relevant scientific terminologies correctly.
- Present the results of an analysis or exercise in a well-structured, logical, coherent and scientifically correct form.
Competences
- Provide qualified contributions to discussions on climate change mechanisms.
