2015 is a critical year for climate action.

This December, world leaders will gather in Paris to adopt a new global agreement to solve the climate crisis. Their meeting will take place as prices for clean, renewable electricity continue to plummet, demand for climate action continues to grow and governments take bold action.

In his session, former Vice President Al Gore will discuss the need for climate action, Live Earth: Road to Paris and the way forward for our civilization.
