In complex and non-linear systems, the only thing we know is that our predictions are unreliable. I fear the reliably unpredictable
I fear the predictable unpredictable. Over the past decade there have been many warnings about Global Warming; precise extrapolations of temperature increases and projections of sea level rise. Such prognostication is understandable, they make the threat concrete to a complacent public. But the reality is that these physical processes are non-linear systems subject to wild fluctuations, with "flips" between alternative equilibrium states. Try to turn that into punchy prose!
