Climate change
Climate change is high on both domestic and international political agendas as countries face up to the huge environmental challenges the world now faces. Whilst this attention is welcome, less energy is being focused on the inevitable impact climate change will have on security issues. The well-documented physical effects of climate change will have knock-on socio-economic impacts, such as loss of infrastructure, resource scarcity and the mass displacement of peoples. These in turn could produce serious security consequences that will present new challenges to governments trying to maintain stability.

Humanity appears caught in a trap with no way out. ‘Business as usual’ is no longer an option. However, halting and reversing our consumption of more and more ‘stuff’ appears likely to trigger a massive depression with serious unemployment and poverty. This is certainly true if all we do is ‘apply the brakes’ without fundamentally redesigning the whole economic system.
