The father of climate change science

Often described as the father of climate change science and occasionally the grandfather (following publication of his book Storms of My Grandchildren) James Hansen took time out from a busy trip attend the Climate Dialogue/C40 Cities Hong Kong conference to talk to CleanBiz Asia executive editor Fergus O'Rorke. As well as hard science Hansen shares his view on business, public policies and China's increasingly influential role in the climate change stakes.
