Collapse of an avifauna: climate change appears to exacerbate habitat loss and degradation

A global assessment of current and future biodiversity vulnerability to habitat loss-climate lossclimate change interactions

Habitat loss is the greatest threat to biodiversity and rapid, human-forced climate change is likely to exacerbate this. Here we present the first global assessment of current and potential future impacts on biodiversity of a habitat loss and fragmentation–climate change (HLF–CC) interaction. A recent meta-analysis demonstrated that the negative impacts of habitat loss and fragmentation have be...

Pollution, habitat loss, fishing, and climate change as critical threats to penguins.

Cumulative human impacts across the world's oceans are considerable. We therefore examined a single model taxonomic group, the penguins (Spheniscidae), to explore how marine species and communities might be at risk of decline or extinction in the southern hemisphere. We sought to determine the most important threats to penguins and to suggest means to mitigate these threats. Our review has rele...

Climate Change, Collapse and Social Choice Theory∗

The enlightenment was a philosophical project to construct a rational society without the need for a supreme being . It opened the way for the creation of market democracy and rapid economic growth. At the same time economic growth is the underlying cause of climate change, and we have become aware that this may destroy our civilization. The principal underpinning of the enlightenment project i...

European avifauna: habitat, migration and endemism

Climate Change and Market Collapse: A Model Applied to Darfur

A recurring argument in the global debate is that climate deterioration is likely to make social conflicts over diminishing natural resources more common in the future. The exact mechanism behind such a development has so far not been successfully characterized in the literature. In this paper, we present a general model of a community populated by farmers and herders who can either divide up l...
