3 August 2015, The Conversation, The scariest part of climate change isn’t what we know, but what we don’t. We know a lot about what climate change will do, but ‘when’ is a tougher question. “It’s tough to make predictions, especially about the future”: so goes a Danish proverb attributed variously to baseball coach Yogi Berra and physicist Niels Bohr.
