This is an accepted version of this page This is the latest accepted revision, reviewed on 10 January 2025. Gas in an atmosphere with certain absorption characteristics This article is about the physical properties of greenhouse gases. For how human activities are adding to greenhouse gases, see Greenhouse gas emissions. Greenhouse gases trap some of the heat that results when sunlight heats ...
Carbon dioxide is the lasing medium in a carbon-dioxide laser, which is one of the earliest type of lasers. Carbon dioxide can be used as a means of controlling the pH of swimming pools, [139] by continuously adding gas to the water, thus keeping the pH from rising. Among the advantages of this is the avoidance of handling (more hazardous) acids.
The concentration of carbon dioxide in a given area can act as a proxy indicator for metabolic function of an individual, or individuals in that area. Since the process of cellular respiration consumes oxygen and produces carbon dioxide the amount of carbon dioxide can be used to infer the amount of oxygen used in the environment specifically ...
Carbon dioxide has unique long-term effects on climate change that are nearly "irreversible" for a thousand years after emissions stop (zero further emissions). The greenhouse gases methane and nitrous oxide do not persist over time in the same way as carbon dioxide. Even if human carbon dioxide emissions were to completely cease, atmospheric ...
Carbonic anhydrase needs a family of carbon base enzymes for the hydration of carbon dioxide and acid–base homeostasis, that regulates PH levels in life. [32] [33] In plant life, liquid water is needed for photosynthesis, the biological process plants use to convert light energy and carbon dioxide into chemical energy. [34] Water makes up 55% ...
Carbon dioxide is removed from the atmosphere primarily through photosynthesis and enters the terrestrial and oceanic biospheres. Carbon dioxide also dissolves directly from the atmosphere into bodies of water (ocean, lakes, etc.), as well as dissolving in precipitation as raindrops fall through the atmosphere. When dissolved in water, carbon ...
Carbon dioxide, the primary gas driving global warming, has increased in concentration by about 50% since the pre-industrial era to levels not seen for millions of years. [6] Climate change has an increasingly large impact on the environment. Deserts are expanding, while heat waves and wildfires are becoming more common. [7]
Carbon intensity or emission intensity of GDP is a measure that evaluates the amount of carbon dioxide (CO 2) emissions produced per unit of GDP. It provides an indication of how efficiently an economy uses carbon-based resources to generate economic output.
