As it is a holiday weekend, it is the time to put on a link to an article that is short and to the point, but deals with complicated matters, the nub of which is that humanity as we know it is doomed.
All with no mention of asteroids, comets, solar storms, warming or cooling or geophysical bye-blows by unhappy passing deities.
It is all down to us and our greedy and rapacious financial ways and demands. This article from Our Finite World by Gail Tverberg, hat tip Some Assembly Required, spells it out in a convincing manner that will get all our twitches going.
Enjoy, while you can.
