It'd be fascinating to see if the doomsday message persisted if all financial motivation was removed from Warmology.
Of course that's never gonna happen so people who essentially get paid for shouting about the end of the world will keep doing what they have to do to keep getting paid. Which is shouting about the end of the world. If you even tried they'd shout even louder till someone chucked them some money. Like a wind turbine manufacturer or something.
Basic tenets of the modern world:
1. If someone tells you something a _lot_ then always question how they stand to benefit from your believing them.
2. If there's money involved you should distrust it in direct proportional to the amount of money stood to be lost/gained.
