Idea with photography

I am embarking on a new way of showing the very real impact of climate change on people around the world by photographing landscapes in selected sites on a set time interval and monitoring changes. I believe that this will make a deeper impression on most people than simply showing graphical projections in scientific language. Sites will predominantly be selected on boundaries between different ecotones to show how these boundaries are shifting. Please give me some input and make suggestions on areas that may lend themselves to this.
