World renowned economist Nouriel Roubini was nicknamed Dr. Doom until his warnings of the 2008 housing crisis and Great Financial Crisis came true - when it was too late.

There are no fewer than ten overlapping, interconnected threats that are so serious Roubini describes them as megathreats - with each one potentially amplifying the others. A Financial Times Economics Book of the Year.
