My father-in-law, Marc Besen AC, turns 100 in December, and his engagement with business and politics remains irrepressible.

Over coffee last week, he asked me this question: climate activists like you have spent the last 20 years trying to convince conservatives about the urgent need to do something about climate change. Yet,when leaders of the Liberals and Nationals propose a nuclear industry in this country to help reduce carbon emissions, you are opposed. Have you examined this possibility with an open mind, and isn’t this your great opportunity to make climate action a bipartisan issue?
