Hope for the Planet: While the Trump Administration continues to dismantle environmental protection rules, and the earth’s temperature continues to rise, I know it’s easy for people to become despondent about climate change. But Mike Bloomberg and Carl Pope believe that we are now in a better position to stop climate change than ever before. In their New York Times bestseller Climate of Hope: How Cities, Businesses, and Citizens Can Save the Planet, now out in paperback, they argue that in the years ahead, cities, businesses, and communities—not Washington or other national governments—can lead and win the battle against global warming. Together, they create a new type of conversation about climate change—one that moves the issue from partisanship to empowerment; from top-down to bottom-up; and from fear to hope.
