Kevin Anderson is deputy director of the Tyndall Centre for Climate Change Research (UK). In this 57-minute talk (given in July, 2011) he tells us straight from the shoulder the truth about global warming and what’s in store for us in the next 20 years as we head for a world that averages 4 degrees Celsius [7 degrees Fahrenheit] warmer than the pre-industrial world — averaging even warmer on land and far warmer at the poles. As Anderson says, if we know the truth about this, then maybe — just maybe — we can do something about it. If we don’t know the truth, then we can do nothing.
