Consequently, many experts from diverse disciplines are uncomfortable with the slow pace of governments in addressing this issue. The growing sense of urgency arises from two concerns:

  • Earth’s climate system may be rapidly approaching a point of no return where large, irreversible and destructive changes, like the gradual disintegration of an ice sheet, become inevitable.
  • To achieve any given temperature goal, the longer we delay action, the steeper emissions reductions will need to be. It’s easier to cut emissions gradually than it is to slash them drastically.
