The Probability of the End of Civilization in the 21st Century
Climate scientists have been calling recently for more research into warming scenarios of 3°C and above because such scenarios are dangerously neglected. According to mainstream models such levels of warming are by no means impossible or even unlikely, and would have catastrophic effects. Luke Kemp and ten colleagues write: Could anthropogenic climate change result in worldwide societal collapse or even eventual human extinction? At present, this is a dangerously underexplored topic. Yet there are ample reasons to suspect that climate change could result in a global catastrophe. The answer to the question in this quote is obviously “yes”, but that’s...
Human Extinction
Apparently, an increasing number of people say that they believe that climate change will cause human extinction. To what extent all of these people are genuinely convinced about this I don’t know, although, for reasons explained elsewhere, I expect that for most of them it is a desperate attempt to find meaning and make sense of an increasingly meaningless and senseless world more than a genuine conviction. Regardless, the topic of human extinction is an interesting one. How likely is human extinction really? And would human extinction actually be a bad thing? These are the two questions I will focus...
Michael Mann versus the “Doomists”
Last month, Breakthrough Australia published a paper by David Spratt and Ian Dunlop that claims that “climate change now represents a near- to mid-term existential threat to human civilisation”. Climate scientist Michael Mann was quick to put down the paper as “overblown rhetoric”. He was quoted as saying that “I respect the authors and appreciate that their intentions are good, but as I have written before, overblown rhetoric, exaggeration, and unsupportable doomist framing can be counteractive to climate action.” The quote by Mann raises a number of questions. Is the report by Spratt and Dunlop “overblown rhetoric” indeed? Does Mann...
Stages of the Anthropocene
preface (2022) There are major mistakes in the predictions and calculations involved in this article. For an attempt to come up with better predictions (and thus, an update of this article), see the SotA-R series. The model results presented in the last episode thereof, suggest 3°C to 5°C of average global warming. (Original post) — Climate scientists don’t often look at the distant future and when they do, their “predictions” are so vague that they hardly count as predictions at all. Most published work on climate change focuses on the current century. There are good reasons, for this, of course...
Fictionalism – or: Vaihinger, Scheffler, and Kübler-Ross at the End of the World
In 1911 the now almost forgotten German philosopher Hans Vaihinger published Die Philosophie des Als Ob (The Philosophy of ‘As if’) in which he argued for something approaching global fictionalism. In the preface to the second English edition of his book he wrote: The principle of Fictionalism . . . is as follows: “An idea whose theoretical untruth or incorrectness, and therewith its falsity, is admitted, is not for that reason practically valueless and useless; for such an idea, in spite of its theoretical nullity may have great practical importance.” Fictionalism is the view that claims in some area of...
