Why Climate Action Is Unstoppable

Recorded at the TED Countdown Summit in Nairobi in June 2025, this talk has Al Gore taking stock of climate action a decade after the Paris Agreement. He challenges “climate realism,” a fossil fuel industry narrative claiming energy transitions are always slow and that the world should focus on adapting rather than cutting emissions.

What it covers

• Why Gore calls “climate realism” a myth
• Falling renewable energy costs and rapid growth in solar, wind and electric vehicles
• Projections of up to two billion climate refugees by 2050
• Why he dismisses carbon capture as a distraction
• Barriers to clean energy investment in developing countries

Why it matters

The talk shows how climate denial has shifted from rejecting the science to questioning whether action is practical. Gore closes on a hopeful note, arguing that the tools to solve the crisis already exist and that political will is a renewable resource.
