Global Climate Emergency: after COP24, climate science, urgency, and the threat to humanity.

This Special Editorial on the Climate Emergency makes the case that although we are living in the time of Global Climate Emergency we are not yet acting as if we are in an imminent crisis. The authors review key aspects of the institutional response and climate science over the past several decades and the role of the economic system in perpetuating inertia on reduction of greenhouse gas emissions. Humanity is now the primary influence on the planet, and events in and around COP24 are the latest reminder that we live in a pathological system. A political economy has rendered the UNFCCC process as yet a successful failure. Fundamental change is urgently required. The conclusions contain recommendations and a call to action now.
