As climate changes, when there is a stress on the resources of an ecosystem, the local inhabitants will face increased burdens. Increased heat, decreasing precipitation, flood, melting of arctic environments all pose threats to humans and our fellow inhabitants of the globe.
That's the message socio-ecologists have been sending for a while now.
Make California dryer, make the Yukon warmer, blanket large Chinese cities in smog, throw a super storm at the Arabian peninsula - all serve to stress the local population. And stressed populations are uneasy populations.
That's the simple message here.
