Defining Voices

Named a UN Champion of the Earth and one of Time's 100 most influential people, Hayhoe has spent two decades studying not just climate science but climate communication — why facts alone fail, and what actually moves people to act.

Henderson's decades-long campaign to replace GDP with real measures of human and planetary wellbeing finds its next generation in Raworth's doughnut framework. Two thinkers, forty years apart, making the same fundamental argument.

Hawken mobilized 200 researchers to rank and model the most substantive paths to reversing global warming — then built a second project to make regeneration the frame that replaces mitigation. A solutions-first thinker before solutions-first was the approach.

Orr argued that the ecological crisis is a crisis of education; Assadourian spent 17 years at Worldwatch documenting the cultural shift required to move beyond consumerism. A conversation about what changing minds at scale actually demands.

For more than two decades Heinberg has been mapping what a post-fossil-fuel world actually demands — not just technically, but economically, politically, and culturally — making him one of the most rigorous analysts of the energy transition ahead.

Henderson reshaped how economists measure progress at the systemic level; Robin reshaped how individuals relate to money, time, and enough. Together they examine the gap between what economies count and what lives actually need.
