Mark Dunlea has written a veritable handbook for challenging climate change. And a download of the book is free by going to GELFNY.org That’s the Green Education and Legal Fund of which Dunlea is chairperson. Teaching a course in Climate Change and Advocacy at Bennington College, Dunlea sought a “basic 101 climate book” and was told by Bill McKibben, co-founder of 350.org, that there was none. So, Dunlea, a long-time environmental activist wrote—as the book is subtitled—“An Introduction to Climate Change and Advocacy.” The central message of the book, as Dunlea explains in this Enviro Close-Up, is: “Fossil fuels are destroying the world.” Damages the burning of fossil fuels are causing include “extreme weather…becoming more common, more expensive and more destructive.” Says Dunlea: “We have to stop burning fossil fuels.” He spotlights the work of Dr. Mark Z. Jacobson, his most recent book “No Miracles Needed,” and how “100% of our energy needs” can be provided “with today’s technology” and “without fossil fuels.” Jacobson heads the Atmosphere/Energy Program and Professor of Civil and Environmental Engineering at Stanford University. Dunlea emphasizes the urgency of the transition to green, carbon-free energy. “It’s now or never,” he says. He also discusses “false climate solutions” including nuclear power. Dunlea co-founded the Ralph Nader-inspired New York Public Interest Research Group and was first chairperson of national PIRG.
