A practical response to global warming

It has been suggested that, in a situation of great uncertainty over a vital issue, we should adopt Blaise Pascal’s strategy. Pascal famously argued that, in a situation in which it could not be proved either that God exists or that he does not exist, with the evidence for and against the question broadly speaking balanced, the rational thing to do is to gamble on his existence. If we win we shall escape judgment, and if we lose there won’t be a judgment to escape. Whereas if we gamble on his non-existence, we shall suffer punishment if we are wrong and be obliterated if we are correct, and we have a 50-50 chance of being wrong.
