Beschreibung:
Climate change is both a cause and an effect of biodiversity change. Along with anthropogenic dispersion, climate change is the main driver of change in the geographical distribution of both beneficial and harmful species, crops, livestock, harvested wild species, pests, predators and pathogens. And the capacity of ecosystems to adapt to climate change depends on the diversity of species they currently support. This paper considers the connection between climate, biodiversity and ecosystem services. The impact of climate change on human wellbeing is measured by the change in ecosystem services caused by climate related change in biodiversity. Similarly, the role of species richness and abundance in climate change mitigation or adaptation is measured by the change in the climate-related services of biodiversity. The categories of ecosystem services are those applied in the millennium ecosystem assessment. The paper first considers how climate and biodiversity have been linked in recent attempts to link the two things. From the side of the natural sciences, this covers the consequences of climate change for various dimensions of biodiversity. From the side of the social sciences, it covers the value of biodiversity in the carbon cycle. It then uses insights from the economic treatment of the relation between biodiversity and ecosystem services to re-evaluate the connection between biodiversity and climate change, and to draw conclusions for climate policy
