Perspectives on Beetles and Climate Change

The response of beetles to climate change during the Quaternary Period is reviewed for the purpose of evaluating their future response to global warming. Beetles responded to Quaternary climatic changes mostly by dispersal, which ultimately led to large scale changes in geographic distribution. Fragmentation and isolation of populations associated with climate change did not result in either hi...

Climate change risks for African agriculture.

The Intergovernmental Panel on Climate Change (IPCC) assessment of major risks for African agriculture and food security caused by climate change during coming decades is confirmed by a review of more recent climate change impact assessments (14 quantitative, six qualitative). Projected impacts relative to current production levels range from -100% to +168% in econometric, from -84% to +62% in ...

A global climate system perspective on African environmental change

Abstract. We review recent advances and current challenges in African climate research and offer a global climate context in which to interpret African environmental change. We classify the various mechanisms that have been proposed as relevant for understanding variations in African rainfall, emphasizing a “tropospheric stabilization” mechanism that is of importance on interannual time scales ...
