The biological and geological future of Earth can be extrapolated based on the estimated effects of several long-term influences. These include the chemistry at Earth's surface, the cooling rate of the planet's interior, gravitational interactions with other objects in the Solar System, and a steady increase in the Sun's luminosity.
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.
Examples of non-anthropogenic risks are an asteroid or comet impact event, a supervolcanic eruption, a natural pandemic, a lethal gamma-ray burst, a geomagnetic storm from a coronal mass ejection destroying electronic equipment, natural long-term climate change, hostile extraterrestrial life, or the Sun transforming into a red giant star and ...
Intelligent extraterrestrial life, if it exists, could invade Earth, either to exterminate and supplant human life, enslave it under a colonial system, exploit the planet's resources, or destroy it altogether. [159]
Earth's surface temperature will reach around 420 K (147 °C; 296 °F), even at the poles. [80] [96] 2.8 billion High estimate until all remaining Earth life goes extinct. [80] [96] 3–4 billion The Earth's core freezes if the inner core continues to grow in size, based on its current growth rate of 1 mm (0.039 in) in diameter per year.
The SpaceX and Tesla pioneer has warned that travel to other planets was necessary as Earth would be engulfed by the Sun. Elon Musk says humans must leave Earth "because sun will engulf our planet ...
Human composting is emerging as an end-of-life alternative that is friendlier to the climate and the Earth — it is far less carbon-intensive than cremation and doesn’t use chemicals involved ...
