Drawdown

1. IDEA 1

   Many solutions already exist

   Hawken and a team of researchers ranked one hundred existing solutions to climate change by their potential to reduce greenhouse gases. They argue that the tools to reverse global warming are already available.

2. IDEA 2

   Drawdown is the goal

   The book defines drawdown as the point when greenhouse gases in the atmosphere begin to decline year after year. The authors treat it as a clear target that can be measured, because it marks the turning point in the climate story.

3. IDEA 3

   Refrigerants matter greatly

   The researchers ranked managing refrigerants, chemicals in fridges and air conditioners, among the most powerful solutions. The book says this is because some of these chemicals trap far more heat than carbon dioxide does, so even small leaks matter.
