Sometimes the available facts are insufficient to totally circumscribe and contain pessimistic speculation as to what the future holds. One must make do as to what one has, and hopefully that will somewhat contain the more severe cases of angst among the more reasonable.
By the way, did you know that about once every million years of so a huge volcanic eruption or asteroid wipes out the bulk of life on this planet, and every 100 million years of so, a mega asteroid wipes out almost all non aquatic life, and that about 3 asteroids a week allegedly get within about 100,000 miles of earth? Also, did you know that Yellowstone is overdue to blow again, and that is the biggest volcanic formation under land on Earth, and if it blows a big one again will kill everything within several hundred miles, and put the grain belt in America under a foot or so of ash? I didn't either until I read the wrong chapter in Bill Bryson's most fascinating book about A Short History of Nearly Everything.
Maybe we should get out worry beads out about THAT!

I'm sure you have read some of my legion of posts on catastrophism. I read Bryson's book in one sitting and found it most interesting as it seemed to hit most all of the high spots.
The difference between things like immigration and super volcanoes, BFRs and climate catastrophes is that the latter don't require that blame be assigned and that one solution is probably as ineffectual as another.
