Fantasy cartography, fictional map-making, or geofiction is a type of map design that visually presents an imaginary world or concept, or represents a real-world geography in a fantastic style. [1] Fantasy cartography usually manifests from worldbuilding and often corresponds to narratives within the fantasy and science fiction genres.
This is a list of fictional countries from published works of fiction (books, films, television series, games, etc.). Fictional works describe all the countries in the following list as located somewhere on the surface of the Earth as opposed to underground, inside the planet, on another world, or during a different "age" of the planet with a different physical geography.
Deforestation, for example, decreases the biosphere's ability to absorb carbon, thus increasing the amount of carbon in the atmosphere. [24] As the industrial use of carbon by humans is a very new dynamic on a geologic scale, it is important to be able to track sources and sinks of carbon in the atmosphere.
The concentration of carbon dioxide (CO 2) in the atmosphere reached 427 ppm (0.0427%) on a molar basis in 2024, representing 3341 gigatonnes of CO 2. [1] This is an increase of 50% since the start of the Industrial Revolution, up from 280 ppm during the 10,000 years prior to the mid-18th century. [2] [3] [4] The increase is due to human ...
The technical term for this is carbon sequestration. The overall goal of carbon farming is to create a net loss of carbon from the atmosphere. [85] This is done by increasing the rate at which carbon is sequestered into soil and plant material. One option is to increase the soil's organic matter content.
Carbon planets might also be located near the Galactic Center or globular clusters orbiting the galaxy, where stars have a higher carbon-to-oxygen ratio than the Sun. When old stars die, they spew out large quantities of carbon. As time passes and more and more generations of stars end, the concentration of carbon and carbon planets, will ...
The concentration of water vapor (a greenhouse gas) varies significantly from around 10 ppm by mole fraction in the coldest portions of the atmosphere to as much as 5% by mole fraction in hot, humid air masses, and concentrations of other atmospheric gases are typically quoted in terms of dry air (without water vapor).
Partly because its concentration of DIC is about 15% higher [26] but mainly due to its larger volume, the deep ocean contains far more carbon—it is the largest pool of actively cycled carbon in the world, containing 50 times more than the atmosphere [7] —but the timescale to reach equilibrium with the atmosphere is hundreds of years: the ...
