Pew Center on the States has a section on Trends to Watch that affect policy making in the US states.
"Trends to Watch starts with an overview of eight major economic, technological, social and environmental trends and issues likely to be profound determinants of the prospects of states in the next 10 years. The story of each trend provides broad context and offers answers to such questions as: What is my state facing? What should I be thinking about?"
Green Wave about climate change is one of the big six. It has data visualization tools for comparing states according to emissions, energy consumption, transportation and other aspects of climate change.
