Despite the title of this book and Asimov’s guide through the possible disasters that could lead to the extinction of human life he remains optimistic and upbeat. He concludes:

“There is nothing that that threatens us with imminent destruction in such a fashion that we are helpless to do something about it. If we behave rationally and humanely, rather than emotionally on such nineteenth century matters as national security and local pride; if we recognise that it is not one’s neighbour who are the enemy, but misery, ignorance, and cold indifference of natural law - then we can solve all the problems that face us. We can deliberately choose to have no catastrophes at all.

And if we do that over the next century we can spread into space and lose our vulnerabilities”

A Choice of Catastrophes was first published in 1979 and has not been updated. It reads at times like a basic primer in the fundamentals of science that holds the universe together and so we are treated to the laws of thermodynamics, gravity and the causes of natural disasters. These are used to back up Asimov’s ideas of how it all works, some of this I had to take on trust because of my limited ability to cope with basic science, however it is written with the average science fiction reader in mind and it would appeal to those readers who want some basic science as a background to their reading. Popular science written by a science fiction author.

Asimov ranks his catastrophes into five classes: starting with the truly cosmic idea of the destruction of the universes. Asimov is a believer in the expanding contracting universe theory, but as the contraction stage will not happen for trillions of years in the future there is no need for us to worry. The second class is a more local cosmic catastrophe that could render our solar system inhabitable; black holes, the death of our sun are explained, again with some basic science to underpin the theories. The third class is the misadventures of the earth itself, for example; the bombardment of extraterrestrial objects, the slowing of the earth, removal of magnetism and changes in climatic conditions. The fourth class is dangers that threaten humanity specifically, although general life would continue: competition with other life forms on earth, and conflicts of intelligence with other species make up this section. The fifth class is man’s capacity to engineer his own destruction.

Asimov introduces his ideas with some brief history of scientific theories before bringing his readers up to date with the latest ideas (that is 1970’s). His method of working is to set up possible catastrophic interventions and then to estimate their risks. This can feel a little repetitive and Asimov is not the most concise of authors when dealing with fact rather than fiction and he does stray at times into over optimistic ideas of mans capacity to expand in the universe. However I found his fifth class of possible catastrophes the most interesting as he briefly covers computerisation, education and the depletion of resources. I learnt a few things, checked up on others (google) and so the book held my interest and so 3.5 stars. ( )

A nerdy-fun read. ( )

Reading a dozen ways our universe, planet, civilization can come to an end could not not be fascinating. ( )
