Ecosystems, Climate and Climate Change

Course content

The focus of the course is on the relations between terrestrial ecosystems and global climate systems. Seen in a historical and present perspective as well as on a temporal and spatial scale, the interactions between climate and ecosystem are put in perspective of the ongoing and future climate change. Further, the course explain how models and data bases are used to develop future climate scenarios and reconstruction of previous climate conditions, as well as the anthropogenic role in the present changes in climate.

Knowledge:

Status of the research in climate changes, models for projection of climate development and the content of greenhouse gasses in the atmosphere. Natural and anthropogenic forcing of climate. Theories and concepts on ecological climatology, terrestrial ecosystems, the global climate system, climate variations, Milankovitch cycles, greenhouse gasses, annual variations in relation to the regional climate and the effects hereof, the relation of vegetation dynamics and CO2 balance, climate models, climate predictions.

Skills:

  • Account for the changes in climate in recent times
  • Account for the relations between the climate and the content of greenhouse gasses in the atmosphere
  • Account for the relations between the climate, ecosystems and land use in different climate zones
  • Identify and explain the interaction between atmospheric circulation and radiation/energy balance and the relation to the global climate zones.
  • Explain and discuss Global weather phenomes as  El Ninõ and NAO and their influence on the weather in the northern Atlantic and Europe.
  • Identify and explain spatiotemporal variations in permafrost processes and ice cover extent in the north Atlantic – causes and consequences.
  • Identify and explain variation in radiation balance and wind climate at different surface types.
  • Explain and discus photosynthesis, evapotranspiration and energy balance in relation to spatiotemporal variation in the vegetation and land use.
  • Describe and interpret ecosystems and vegetation dynamics – carbon budget, net primary production, biogeography and vegetation modelling.
  • Identify and describe the carbon exchange I relation to agricultural areas and other ecosystems under human influence and the problems caused by deforestation, desertification and change in land use.

 

Competences:

  • Ability communicate knowledge about the climate change problem in a written assignment.
  • Insight in the phenonomen of climate change and ability to destinguish between anthropogic and natural causes.
