Now that we are in an ever-warming world, is it time for us humans to use our powers for good? The idea of geo-engineering is seriously being considered today at a conference in Washington.
Joining Madeleine to discuss the efforts to reverse climate change with geo-engineering is Roger Pielke at the University of Colorado. He's a professor of Environmental Studies and author of the new book, The Climate Fix -- What Scientists and Politicians Won't Tell You About Global Warming.
Also, KPCC's Sanden Totten reports on how people are making money off climate change investments.
