Neal Town Stephenson is an American writer known for his works of speculative fiction. His novels have been categorized as science fiction, historical fiction, cyberpunk, postcyberpunk, and baroque.
The Younger Dryas was a return to glacial conditions after the Late Glacial Interstadial, which temporarily reversed the gradual climatic warming after the Last Glacial Maximum (LGM) started receding around 20,000 BP. It is named after an indicator genus, the alpine-tundra wildflower Dryas octopetala, as its leaves are occasionally abundant in late glacial, often minerogenic-rich sediments, such as the lake sediments of Scandinavia.
Snow Crash is a science fiction novel by the American writer Neal Stephenson, published in 1992. Like many of Stephenson's novels, it covers history, linguistics, anthropology, archaeology, religion, computer science, politics, cryptography, memetics, and philosophy.
Global dimming is the reduction in the amount of global direct irradiance at the Earth's surface that has been observed since systematic measurements began in the 1950s. The effect varies by location, but worldwide it has been estimated to be of the order of a 4–20% reduction. However, after discounting an anomaly caused by the eruption of Mount Pinatubo in 1991, a very slight reversal in the overall trend has been observed.
Planetary engineering is the development and application of technology for the purpose of influencing the environment of a planet. Planetary engineering encompasses a variety of methods such as terraforming, seeding, and geoengineering.
Climate engineering, or commonly geoengineering, is deliberate and large-scale intervention in the Earth's climate system. The main category of climate engineering is solar geoengineering or solar radiation management. Solar geoengineering, or solar radiation modification, would reflect some sunlight back to space to limit or reverse human-caused climate change.
Climate change mitigation consists of actions to limit global warming and its related effects. This is mainly reductions in human emissions of greenhouse gases (GHGs) as well as activities that reduce their concentration in the atmosphere. It is one of the ways to respond to climate change, along with adaptation. Fossil fuels emit most carbon dioxide(CO2) and greenhouse gas as a whole. The most important challenge is to stop burning coal, oil, and gas and use only clean energy. Due to massive price drops, wind power and solar photovoltaics (PV) are increasingly out-competing oil, gas and coal though these require energy storage and improved electrical grids. As low-emission energy is deployed at large scale, transport and heating can shift to these mostly electric sources. Mitigation of climate change may also be achieved by changes in agriculture, transport, forest-management, waste management, buildings, and industrial systems. Methane emissions, which have a high short-term impact, can be targeted by reductions in dairy products and meat consumption.
Saskia is a Germanic feminine given name. There are at least two different sources of the name. One is of North German and Northeast Netherlands origin, where it originally meant "a Saxon woman".

Charles Yu is an American writer. He is the author of the novels How to Live Safely in a Science Fictional Universe and Interior Chinatown as well as the short-story collections Third Class Superhero and Sorry Please Thank You. In 2007 he was named a "5 under 35" honoree by the National Book Foundation.
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.
Solar geoengineering, or solar radiation modification (SRM) is a type of climate engineering in which sunlight would be reflected back to space to limit or reverse human-caused climate change. It is not a substitute for reducing greenhouse gas emissions, but could act as a temporary measure to limit warming while emissions of greenhouse gases are reduced and carbon dioxide is removed. The two most studied methods for SRM are stratospheric aerosol injection and marine cloud brightening.
Stratospheric sulfur aerosols are sulfur-rich particles which exist in the stratosphere region of the Earth's atmosphere. The layer of the atmosphere in which they exist is known as the Junge layer, or simply the stratospheric aerosol layer. These particles consist of a mixture of sulfuric acid and water. They are created naturally, such as by photochemical decomposition of sulfur-containing gases, e.g. carbonyl sulfide. When present in high levels, e.g. after a strong volcanic eruption such as Mount Pinatubo, they produce a cooling effect, by reflecting sunlight, and by modifying clouds as they fall out of the stratosphere. This cooling may persist for a few years before the particles fall out.
Stratospheric aerosol injection is a proposed method of solar geoengineering to reduce human-induced global warming. This would introduce aerosols into the stratosphere to create a cooling effect via global dimming, which occurs naturally from volcanic eruptions. It appears that stratospheric aerosol injection, at a moderate intensity, could counter most changes to temperature and precipitation, take effect rapidly, have low direct implementation costs, and be reversible in its direct climatic effects. The Intergovernmental Panel on Climate Change concludes that it "is the most-researched [solar geoengineering] method, with high agreement that it could limit warming to below 1.5°C." However, like other solar geoengineering approaches, stratospheric aerosol injection would do so imperfectly and other effects are possible, particularly if used in a suboptimal manner.

Novim is a non-profit group at the University of California, Santa Barbara that organizes teams for objective scientific study of global issues and identification options for addressing the concerns, based upon a collaborative problem-solving approach used in the field of physics.
Climate fiction is literature that deals with climate change and global warming. Not necessarily speculative in nature, works may take place in the world as we know it or in the near future. 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. Technologies such as climate engineering or climate adaptation practices often feature prominently in works exploring their impacts on society. Climate fiction is distinct from petrofiction which deals directly with the petroleum culture and economy.
Cirrus cloud thinning (CCT) is a proposed form of climate engineering. Cirrus clouds are high cold ice that, like other clouds, both reflect sunlight and absorb warming infrared radiation. However, they differ from other types of clouds in that, on average, infrared absorption outweighs sunlight reflection, resulting in a net warming effect on the climate. Therefore, thinning or removing these clouds would reduce their heat trapping capacity, resulting in a cooling effect on Earth's climate. This could be a potential tool to reduce anthropogenic global warming. Cirrus cloud thinning is an alternative category of climate engineering, in addition to solar radiation management and greenhouse gas removal.

Wagner writes the Risky Climate column for Bloomberg News, and is the co-author, with Martin L. Weitzman, of Climate Shock, a Top 15 Financial Times-McKinsey Business Book of the Year 2015.
The Ministry for the Future is a climate fiction ("cli-fi") novel by American science fiction writer Kim Stanley Robinson published in 2020. Set in the near future, the novel follows a subsidiary body, established under the Paris Agreement, whose mission is to act as an advocate for the world's future generations of citizens as if their rights are as valid as the present generation's. While they pursue various ambitious projects, the effects of climate change are determined to be the most consequential. The plot primarily follows Mary Murphy, the head of the titular Ministry for the Future, and Frank May, an American aid worker traumatized by experiencing a deadly heat wave in India. Many chapters are devoted to other characters' accounts of future events, as well as their ideas about ecology, economics, and other subjects.
