There’s an iceberg ahead of us, we’re on the Titanic, and everyone’s just sipping cocktails and pretending everything’s just fine. My public talks address the multi-faceted problem of climate change and clean energy. I speak in a bare-knuckled and pragmatic style that combines economic, scientific, political and financial expertise. I tell it like it is, whether to naive environmentalists or to entrenched fossil-fuel barons. It’s high time we spent what social capital we have, and stand up to talk about what’s coming – because it seems our politicians and captains of industry just can’t manage to do it.
