Further to the blog below on greening the military, some may be interested in the work of Gregory White and Jon Barnett discussing the dangers of securitising climate change.
The work of both scholars highlights empirical research that dispels many truths bound up with the climate change and security frame, including the image of immanent chaos from swathes of immigrants fleeing climate related disasters in the South. White suggests that contrary to belief in the threat posed by environmental migrants, research indicates that during times of drought and other climate extremes people are less inclined to move, and when they do move, they are more likely to migrate to another region within their own country or a neighbouring country than move to another continent as commonly theorised.
