Sue Owen and Lisa Hopkinson aren't climate scientists or economists. But between them they've uncovered something that should worry anyone with a workplace pension: the assumptions used to model climate risk are, in their words, ridiculous - and the people responsible for billions of pounds don't seem to see it.In this conversation they explain how the Derbyshire Pension Fund's own analysis treats 4°C of warming as a roughly 1% hit to returns, why a chain of advisors, consultants and councillors keeps "batting away" every question, and what they think everyone with a local authority pension should be asking right now.Guests:Sue Owen — Derbyshire Pensioners Action GroupLisa Hopkinson — Divest Derbyshire
