* In ''[[Literature/TheEndAndAfterwards]]'', the impact of ''Star Pioneer'' is a 4.5. Human extinction is not immediate, but nearly certain within 50 years. Much, perhaps most of the biosphere is equally doomed.

* In the RiftwarCycle by Raymond E. Feist, Kelewan gets this, not once, but '''twice'''. '''''In the same book.''''' First it starts getting swallowed by an ever-expanding portal to what amounts to the second circle of hell, powered by the deaths of the army trying to stop it. Then, to put an end to ''that'' threat, [[AWizardDidIt Pug]] [[ColonyDrop created a gigantic rift portal that basically slammed a large part of Kelewan's moon into its surface at extreme speed.]] Luckily, a good part of the population escaped to another world.

* In ''Literature/TheMoteInGodsEye'', the Earth is a radioactive wasteland kept as a military training preserve by the Empire of Man, as a lesson to all young officers in the Imperial Fleet "to show them what the Empire exists to prevent." The only places on Earth that can support life are the high mountaintops (ironically, some Jamaican Blue Mountain coffee plants have survived the Apocalypse, and they've all been declared the private property of the Emperor for his exclusive use. Smart Emperor...) At the end of the book, [[spoiler:this is averted, as society is able to deal with the asteroid by some unspecified means]].

* Creator/IsaacAsimov's ''{{Foundation}}'' series has a galactic empire that has lost knowledge of where Earth ''is'', although it is alluded to several times that it has been rendered fatally radioactive through nuclear war. The protagonists eventually find it.

* The conclusion of Dougal Dixon's ''ManAfterMan'' finds the Earth almost totally stripped of life by the evolved, no-longer-recognizable descendents of human space colonists. Its contaminated atmosphere no longer supports any organisms, such that only a handful of native species survive, clinging to deep-sea hydrothermal vents.
* In ''DownToASunlessSea'', the last nuclear war wipes out almost everyone, except two planeloads of people, who have to run [[spoiler:to Antarctica to start over]], then they discover that [[spoiler:the nuclear weapons have knocked the planet off its axis, meaning that Antarctica is soon going to be in the tropics]]. Depending on which ending your copy has, either it's the end of the world [[spoiler:at which point God steps in to begin all over again, with the last two human survivors the new Adam and Eve]], or they will go out to rebuild the world.

* In ''[[TheQuantumThief The Fractal Prince]]'' the Sobornost mind-upload collective has purged most of Earth's surface from life after uploading perfect copies to their giant databanks, and a GreyGoo-nanotech called Wildcode did the rest. Only one city, ironically protected by the Wildcode, still has baseline human population. [[spoiler:By the end even it's gone, after Matjek Chen unleases the Dragons, an even more destructive GreyGoo weapon, on the planet in order to retrieve a copy of his past self. In subversion, upload copies of people continue to live in the Wildcode itself until Chen's purge]]. Amusingly, the sequel novel, ''The Causal Angel'' reveals that the catalyst for all these events was [[spoiler:a deliberately engineered planetwide stockmarket crash.]]

** The Cretaceous-Paleogene Extinction is the most famous. Probably caused by an asteroid impact, it killed 75% of all species, including the Dinosaurs.

* The [[SuddenDownerEnding final episode]] of ''{{Series/Dinosaurs}}''. [[MikeNelsonDestroyerOfWorlds Earl Sinclair]] unwittingly engineers a series of catastrophies that causes the extinction of ''all plant life'', and eventually dinosaurs with it. But the scale is so far beyond what really happened to the dinosaurs, it could go beyond even Class 4 on the AW scale.

*** Actually, the current (relatively minor) extincion process had been going on for a while. Lots of species of large mammals have been lost in the past 50-80 thousand years. And while humans are most likely part of the reason for the extinction, there is also climate change (no, not the one we have been causing since the 20th century) and the apparition of new diseases are also to be blamed.

* ''{{Homestuck}}'': [[spoiler: After Her Imperious Condescension took over Post-Scratch Earth, she turned it into a CrapsackWorld and caused the collapse of civilization and a series of holocausts, [[KillEmAll eventually just flooding the planet]]]]. This should have wiped out most of Earth's biosphere, but apparently some life still survived.
