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 extinction of plants would cause the demise of almost all animal life since plants are the base of much of the animal food chain. [12] [13] In about one billion years, solar luminosity will be 10% higher, causing the atmosphere to become a "moist greenhouse", resulting in a runaway evaporation of the oceans.
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 ...
Dresbachian extinction event: 502 Ma: End-Botomian extinction event: 517 Ma: Precambrian: End-Ediacaran extinction: 542 Ma: Anoxic event [45] Great Oxygenation Event: 2400 Ma: Rising oxygen levels in the atmosphere due to the development of photosynthesis as well as possible Snowball Earth event. (see: Huronian glaciation.)
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.
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 ...
For example, there is approximately one extinction estimated per million species years. [7] From a purely mathematical standpoint this means that if there are a million species on the planet earth, one would go extinct every year, while if there was only one species it would go extinct in one million years, etc.
By Aug. 1, 2018, the Global Footprint Network anticipates humanity will have exhausted more of Earth's resources than it can regenerate within one year.
