I guess, Global Warming?
Bush’s ... er ... Trump’s fault!
One of the super volcanoes goes off, any of them, and except for those within range of being incinerated by the ash and rock fall, warming will be the very last thing we will have to worry about. Growing food without sunlight and not freezing to death in a year or two long winter will suddenly be a top priority.
This was predicted last week by an earthquake specialist that I monitor. See the link below.
