The human dimensions of global environmental change extend beyond policy and economic applications and include the role of values and worldviews expressed through human behavior and opinions. At the core of our response to environmental changes, and the science that is warning us about what is to come, is the debate about whether we should: a. act now with deep structural changes and without regrets to avoid the worst case scenarios, b. make very small and incremental changes based only on what we know for certain will come, or c. wait and see with reactive measures to avoid making changes that were not necessary. Surely, many of you have had these debates. For this blog, you must make a case for one of these three approaches. Use material from class as well as any credible third party materials in order to develop your argument. Use a minimum of two strong sources (one of which must be a peer-reviewed journal article, just as for the first blog).
