The ethical case for taking on the climate crisis | Al Gore, Wanjira Mathai & Karenna Gore (TED Countdown House)

For the first time in climate negotiations, leaders are asking the question that actually matters: not just how do we solve the climate crisis — but why aren’t we? Join Nobel laureate Al Gore for an in-depth conversation with Wanjira Mathai and Karenna Gore, leaders of the Global Ethical Stocktake: an urgent, values-first reset that seeks to center justice, phase out fossil fuels and elevate Indigenous and Global South leadership. Discover the initiative that’s making fossil fuel lobbyists squirm and climate veterans hopeful — before the world moves on to COP31.
