Every year the good folk over at The World Economic Forum publish a report on the most worrying global risks.
They rank them according to likelihood as well as impact.
In 2015 they flagged 'Infectious diseases' as the 2nd most concerning risk when it comes to its impact (not exactly a Black Swan event then if this was something flagged by a publicly available report five years before we had the joy of experiencing a global pandemic first-hand).
This year - the threats are mainly related to climate change and extreme weather events.
Threats on the horizon which most of the world happily carry on ignoring.
Granted this is not exactly a light, laugh-a-minute bedtime read.
What is quite entertaining though is that towards the back of the report, the researchers asked a few 'experts' to imagine a few unimaginable catastrophes to open up our minds as to some weird and outlandish disasters that may also affect the future of the world.
It's part science fiction, part 'that's not so crazy', but a very useful exercise none the less.
