This is expected to occur between 1.5 and 4.5 billion years from now. [11] A high obliquity would probably result in dramatic changes in the climate and may destroy the planet's habitability. [41] When the axial tilt of the Earth exceeds 54°, the yearly insolation at the equator is less than that at the poles. The planet could remain at an ...

In Christian belief, the Last Judgement is an apocalyptic event where God makes a final judgement of all people on Earth. Predictions of apocalyptic events that will result in the extinction of humanity, a collapse of civilization, or the destruction of the planet have been made since at least the beginning of the Common Era.

This is much faster than the expected “background” extinction rate, or the rate at which species would naturally die off without outside influence — in the absence of human beings, these 73 ...
According to a study published in the journal 'Science Advances', planet Earth is entering its sixth period of mass extinction. One of the authors noted, "If it is allowed to continue, life would ...
Scientists say the mass extinction 250 million years ago offers a timely warning to humanity of what can happen when ecosystems change too fast for life to keep up.
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.
More significantly, the current rate of global species extinctions is estimated as 100 to 1,000 times "background" rates (the average extinction rates in the evolutionary time scale of planet Earth), [71] [72] faster than at any other time in human history, [73] [74] while future rates are likely 10,000 times higher.
