Catastrophic climate change is not as dramatic as the above catastrophes but it is 100% likely.
For example, the World Health Organization and the World Economic Forum both listed climate change and its effects as one of their top risks for 2019.
Recent UN talks heard climate change was already "a matter of life and death" for many regions. While many, including Sir David Attenborough, believe it could lead to the collapse of civilisations and the extinction of "much of the natural world".
I should point out that when the western Roman empire collapsed, most Romans believed they were still part of the Roman empire. There were no daily newspapers to announce the end of civilization then. It requires hindsight to see clearly that a civilization has collapsed.
All civilizations either have or will collapse. The U.S. is the leading country of Western civilization and will most likely go down with Western civilization. It is not a question of if but when. Most likely Western civilization will not last beyond 2500 A.D. but who really knows? Let’s try not to make a mess of things!
