Put simply, the challenge of human-driven climate change can be defined by three key points:
1. There is too much carbon dioxide and other greenhouse gases in our atmosphere.
2. The insulating effect of these molecules means less of the earth’s heat reflects into space.
3. The more heat that gets trapped, the more it changes our global systems. From directly melting ice caps to disrupting historic ocean and wind currents, boosting the intensity of storms, and the length and duration of droughts.
