A seminal publication years ago called on the environmental science community to undertake examinations of critical goals to ensure “useful” services to society (Lubchenco 1998). That paper stated the needs of society included more comprehensive information, understanding and technologies … "to move toward a more sustainable biosphere - one which is ecologically sound, economically feasible, and socially just." This required "new fundamental research, faster and more effective transmission of new and existing knowledge to policy and decision-makers, and better communication of this knowledge to the public". Over twenty years later, and confronted with a global climatic emergency, we must examine successes and failures, and develop strategies to break down existing barriers to progress. A rebalancing is required, from the ‘discovery’ to the 'delivery’ of societal values and commitments. The session will call on leaders to identify practical ways to accelerate societal action on climate change.
