Nuclear war is an often-predicted cause of the extinction of humankind. [1]Human extinction or omnicide is the hypothetical end of the human species, either by population decline due to extraneous natural causes, such as an asteroid impact or large-scale volcanism, or via anthropogenic destruction (self-extinction), for example by sub-replacement fertility.
The highest estimate for the time it would take for all nucleons in the observable universe to decay, provided they do not decay via the above process but instead through any one of many different mechanisms allowed in modern particle physics (higher-order baryon non-conservation processes, virtual black holes, sphalerons, etc.) on time scales ...

By 2.8 billion years from now, the surface temperature of the Earth will have reached 422 K (149 °C; 300 °F), even at the poles. At this point, any remaining life will be extinguished due to the extreme conditions. What happens beyond this depends on how much water is left on the surface.
At the same time, hot weather is a killer: ... a 52-year-old Atlanta man, was rescued from his apartment during a heat wave in 1980. ... people will need to adapt in order to survive. This year, ...
Assume, for simplicity, that the total number of humans who will ever be born is 60 billion (N 1), or 6,000 billion (N 2). [6]If there is no prior knowledge of the position that a currently living individual, X, has in the history of humanity, one may instead compute how many humans were born before X, and arrive at say 59,854,795,447, which would necessarily place X among the first 60 billion ...
It was published in the United Kingdom under the title Our Final Century: Will the Human Race Survive the Twenty-first Century?. The premise of the book is that the Earth and human survival are in far greater danger from the potential effects of modern technology than is commonly realised, and that the 21st century may be a critical moment in ...
