Climate change will have huge impact on our mental health

Everyone's worrying about resource management and the spooky, unpredictable changes in the ecosystem. We fret over which areas will get flooded as sea levels rise. We estimate the odds of wars over clean water, and we tally up the species — polar bears, whales, wading birds — that'll go extinct.

But we should also be concerned about the huge toll climate change will inflict on our mental health. In the modern, industrialized West, many of us have forgotten how deeply we rely on the stability of nature for our psychic well-being.

it's a pretty natural human urge to identify with a place and build one's sense of self around its comforts and permanence. I live in Manhattan, where the globe-hopping denizens tend to go berserk if their favorite coffee shop closes down.

we may simply be rediscovering a syndrome that we thought was dead and buried. Back in the 1940s, the military considered homesickness to be a serious and potentially fatal illness, because drafted soldiers who got shipped overseas would often become savagely depressed.

But that may be changing rapidly. In a world that's quickly heating up and drying up, you can't go home again — even if you never leave.
