The most noteworthy aspect of this compilation is likely to be the wide variety of contributions that have been made in promoting peace, security, climate concern, sustainability, and/or the energy transition. For individuals whose work was only dimly perceived, if at all, it has been illuminating for us to find out more about what they have done and are doing. We hope that readers will similarly find their horizons to be widened and deepened.
Most of the 40 Profiles in this section suggest little or no collaboration or influence among these individuals, with one large and one small exception. The large exception involves the 29 scientists that came together to introduce the important concept of “planetary boundaries” in 2009; seven of them are profiled below: in addition to lead author Johan Rockstrom, they include Costanza, Crutzen, Folke, Schellnhuber, and Steffen. The small instance of collaboration is between Lovins and von Weizsaeker on radical “Factor 5” resource efficiency. Many of the authors described below do collaborate, however, but not with others chosen for this list.
