A book to help the general public and students understand the climate justice debate. Includes my 1989 class handout based on the Brundtland Report of 1987 "Our Common Future" and the January 1989 special issue of Time Magazine, "Planet of the Year: Endangered Earth." I point out the similarities between Klein's bestseller, "This Changes Everything: Capitalism vs. the Climate," and Pope Francis' climate encyclical, "Laudato Si." I also argue that both Pope Francis and Klein, while appearing to call into question capitalism itself, are really taking aim at its unbridled, neoliberal version. Also includes recent developments on climate justice issues. A SPECIAL ATTENTION HAS BEEN GIVEN TO PROVIDING HYPERLINKS, ESPECIALLY TO VIDEOS. THESE SHOULD MAKE IT MUCH EASIER AND INTERESTING TO UNDERSTAND THE FUNDAMENTALS OF CLIMATE. CHANGE.
