"We're standing on the threshold of a different planet, it's going to happen in our lifetime."
- Susan Solomon, Atmospheric Chemist, MIT

Climate change threatens our homes, our food supply, and our jobs. Though the dangers are clear, solutions can seem out of reach. There is, however, hope from history. A number of environmental success stories from the last half century counters this narrative of impossibility and provides a message of hope, determination and action.
