The worst Phanerozoic event, the Permian–Triassic extinction, devastated life on Earth, killing over 90% of species. Life seemed to recover quickly after the P-T extinction, but this was mostly in the form of disaster taxa, such as the hardy Lystrosaurus. The most recent research indicates that the specialized animals that formed complex ...
The estimated end of the Sun's current phase of development, after which it will swell into a red giant, either scorching or swallowing Earth, will occur around five billion years from now. However, as the Sun grows gradually hotter (over millions of years), Earth may become too hot for life as early as one billion years from now. [213] [214] [215]
The Earth will naturally become uninhabitable due to the Sun's stellar evolution, within about a billion years. [149] In around 1 billion years from now, the Sun's brightness may increase as a result of a shortage of hydrogen, and the heating of its outer layers may cause the Earth's oceans to evaporate, leaving only minor forms of life.

An event that could cause human extinction or permanently and drastically curtail humanity's existence or potential is known as an "existential risk". [ 4 ] In the 21st century, a number of academic and non-profit organizations have been established to research global catastrophic and existential risks, formulate potential mitigation measures ...
Nickelback may be part of the reason we have life on Earth. Now, the researchers weren’t just super into late-90s Canadian hard rock—there’s a scientific reason behind the moniker.
Some of the more extreme warnings of civilizational collapse caused by climate change, such as a claim that civilization is highly likely to end by 2050, have attracted strong rebutals from scientists. [4] [5] The 2022 IPCC Sixth Assessment Report projects that human population would be in a range between 8.5 billion and 11 billion people by ...

Permian–Triassic boundary at Frazer Beach in New South Wales, with the End Permian extinction event located just above the coal layer [2]. Approximately 251.9 million years ago, the Permian–Triassic (P–T, P–Tr) extinction event (PTME; also known as the Late Permian extinction event, [3] the Latest Permian extinction event, [4] the End-Permian extinction event, [5] [6] and colloquially ...
