The Holocene extinction, or Anthropocene extinction, is the ongoing extinction event caused by humans during the Holocene epoch. These extinctions span numerous families of plants and animals, including mammals, birds, reptiles, amphibians, fish, and invertebrates, and affecting not just terrestrial species but also large sectors of marine life. With widespread degradation of biodiversity hotspots, such as coral reefs and rainforests, as well as other areas, the vast majority of these extinctions are thought to be undocumented, as the species are undiscovered at the time of their extinction, which goes unrecorded. The current rate of extinction of species is estimated at 100 to 1,000 times higher than natural background extinction rates and is increasing. During the past 100–200 years, biodiversity loss and species extinction have accelerated, to the point that most conservation biologists now believe that human activity has either produced a period of mass extinction, or is on the cusp of doing so. As such, after the "Big Five" mass extinctions, the Holocene extinction event has also been referred to as the sixth mass extinction or sixth extinction; given the recent recognition of the Capitanian mass extinction, the term seventh mass extinction has also been proposed for the Holocene extinction event.
Apocalyptic and post-apocalyptic fiction is a subgenre of science fiction in which the Earth's civilization is collapsing or has collapsed. The apocalypse event may be climatic, such as runaway climate change; astronomical, such as an impact event; destructive, such as nuclear holocaust or resource depletion; medical, such as a pandemic, whether natural or human-caused; end time, such as the Last Judgment, Second Coming or Ragnarök; or any other scenario in which the outcome is apocalyptic, such as a zombie apocalypse, cybernetic revolt, technological singularity, dysgenics or alien invasion.
Nick Bostrom is a Swedish philosopher at the University of Oxford known for his work on existential risk, the anthropic principle, human enhancement ethics, whole brain emulation, superintelligence risks, and the reversal test. He is the founding director of the Future of Humanity Institute at Oxford University.
Oryx and Crake is a 2003 novel by Canadian author Margaret Atwood. She has described the novel as speculative fiction and adventure romance, rather than pure science fiction, because it does not deal with things "we can't yet do or begin to do", yet goes beyond the amount of realism she associates with the novel form. It focuses on a lone character called Snowman, who finds himself in a bleak situation with only creatures called Crakers to keep him company. The reader learns of his past, as a boy called Jimmy, and of genetic experimentation and pharmaceutical engineering that occurred under the purview of Jimmy's peer, Glenn "Crake".
Space and survival is the idea that the long-term survival of the human species and technological civilization requires the building of a spacefaring civilization that utilizes the resources of outer space, and that not doing this might lead to human extinction. A related observation is that the window of opportunity for doing this may be limited due to the decreasing amount of surplus resources that will be available over time as a result of an ever-growing population.
Apocalypse is a genre of revelatory literature, or a large-scale catastrophic event.
Human extinction 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.
Doomer and, by extension, doomerism are terms which arose primarily on the Internet to describe people who are extremely pessimistic or fatalistic about global problems such as overpopulation, peak oil, climate change, pollution, nuclear weapons, and runaway artificial intelligence. Some doomers assert that there is a possibility these problems will bring about human extinction.
Societal collapse is the fall of a complex human society characterized by the loss of cultural identity and of social complexity as an adaptive system, the downfall of government, and the rise of violence. Possible causes of a societal collapse include natural catastrophe, war, pestilence, famine, economic collapse, population decline or overshoot, mass migration, and sabotage by rival civilizations. A collapsed society may revert to a more primitive state, be absorbed into a stronger society, or completely disappear.
References to climate change in popular culture have existed since the late 20th century and increased in the 21st century. Climate change, its impacts, and related human-environment interactions have been featured in nonfiction books and documentaries, but also literature, film, music, television shows and video games.
A nuclear holocaust, also known as a nuclear apocalypse, nuclear annihilation, nuclear armageddon, or atomic holocaust, is a theoretical scenario where the mass detonation of nuclear weapons causes globally widespread destruction and radioactive fallout. Such a scenario envisages large parts of the Earth becoming uninhabitable due to the effects of nuclear warfare, potentially causing the collapse of civilization and, in the worst case, extinction of humanity and/or termination of most biological life on Earth.
The Year of the Flood is a novel by Canadian author Margaret Atwood, the second book of her dystopian trilogy, released on September 22, 2009, in Canada and the United States, and on September 7, 2009, in the United Kingdom. The novel was mentioned in numerous newspaper review articles looking forward to notable fiction of 2009.
A global catastrophic risk or a doomsday scenario is a hypothetical event that could damage human well-being on a global scale, even endangering or destroying modern civilization. An event that could cause human extinction or permanently and drastically curtail humanity's existence or potential is known as an "existential risk."
Climate fiction is literature that deals with climate change. Generally speculative in nature but inspired by climate science, works may take place in the world as we know it, in the near future or in fictional worlds experiencing climate change. The genre frequently includes science fiction and dystopian or utopian themes, imagining the potential futures based on how humanity responds to the impacts of climate change. The genre typically focuses on anthropogenic climate change and other environmental issues as opposed to weather and disaster more generally. Technologies such as climate engineering or climate adaptation practices often feature prominently in works exploring their impacts on society.
MaddAddam is a novel by Canadian writer Margaret Atwood, published on 29 August 2013.
Catastrophes in popular culture includes real and fictional disasters, as depicted by the media, and are considered social events. Disaster movies made in Hollywood are part of the American pop culture. Catastrophe types can include hostile aliens, climate change/global warming, environmental disasters, financial crises, natural disaster, nuclear apocalypse, pandemics, super heros, terrorist attacks, zombies and other technological meltdowns.
The term collapsology is a neologism used to designate the transdisciplinary study of the risks of collapse of industrial civilization. It is concerned with the general collapse of societies induced by climate change, as well as "scarcity of resources, vast extinctions, and natural disasters." Although the concept of civilizational or societal collapse had already existed for many years, collapsology focuses its attention on contemporary, industrial, and globalized societies.
Weather is a 2020 novel by American writer Jenny Offill. The novel is narrated by a college librarian, Lizzie. The book takes place before and after Donald Trump becomes president of the United States and depicts Lizzie's family life and her concerns about climate change. The novel received mostly positive reviews, with favorable comparisons to Offill's previous novel, Dept. of Speculation and praise for its structure.
Scenarios in which a global catastrophic risk creates harm have been widely discussed. Some sources of catastrophic risk are anthropogenic, such as global warming, environmental degradation, and nuclear war. Others are non-anthropogenic or natural, such as meteor impacts or supervolcanoes. The impact of these scenarios can vary widely, depending on the cause and the severity of the event, ranging from temporary economic disruption to human extinction. Many societal collapses have already happened throughout human history.
Climate change and civilizational collapse refers to a hypothetical risk of the impacts of climate change reducing global socioeconomic complexity to the point complex human society effectively ends around the world, with humanity reduced to a less developed state. This hypothetical risk is typically associated with the idea of a massive reduction of human population caused by the direct and indirect impacts of climate change, and often, it is also associated with a permanent reduction of the Earth's carrying capacity. Finally, it is sometimes suggested that a civilizational collapse caused by climate change would soon be followed by human extinction.
