This story originally appeared on Bulletin of the Atomic Scientists and is part of the Climate Desk collaboration. When I pull into a parking lot in my Toyota 4Runner, I hope I won\u2019t see any of my friends who are environmental activists. I hope I\u2019ll fit into the eco-conscious (read small) parking spaces at some of the places I shop. I feel like a skinny-car person in a fat-truck body.
