Fall of the Roman Empire 2.0

Like most people concerned with the environment, I remain mystified by the attitudes of governments. Let us be perfectly clear about this: every single 'worst case scenario' scientific research has come up with so far has proved to be the best case. So when we are told that the threat we are facing is equivalent to the Second World War, perhaps a more credible marker should be laid down.

The threat we are trying to stave off is the worst humanity has faced since the fall of the Roman empire.

OK?
