WRI Climate Director Jennifer Morgan describes COP 21 as "a chance to change course together through a new form of international cooperation—hopefully in time to save the planet."

The international community has adopted a goal to limit global warming below 2°C (3.6°F) above preindustrial levels (and consider 1.5 degrees C) in order to avoid some of the worst climate impacts. However, the 2°C goal does not easily guide every day decision-making because it does not state who needs to act, by how much and by when. So negotiators are considering a second, complementary goal which would operationalize the target to limit warming below 2°C. Many have termed this a “long-term goal” which would aim to send a much clearer signal to the world what pathway key players need to follow to stay below 2°C.
