An inverted look at climate change
What's different about their story is that they don't talk about climate change and its potential impacts; they look at the human and natural systems upon which we depend and how climate changes might send them towards tipping points. In other words, the path of conjecture is shorter.
I encourage you to read their paper in its entirety. Its claims seem well footnoted, although I have not studied the references yet.
After you read it, I'm curious in your responses. Where do you think our vulnerabilities lie? What can we do to ameliorate the effects of the stresses Schwarz, Gilman, and Randall describe? How should and can we modify the systems in which we live and work to make them more resilient in the face of such changes? Is this the time for a Y2K-like approach to climate change and related issues (no matter your thoughts about Y2K)?
