Pulmonology, critical care medicine. Hypercapnia (from the Greek hyper = "above" or "too much" and kapnos = "smoke"), also known as hypercarbia and CO2 retention, is a condition of abnormally elevated carbon dioxide (CO 2) levels in the blood. Carbon dioxide is a gaseous product of the body's metabolism and is normally expelled through the lungs.
Carbon sequestrationis the process of storing carbon in a carbon pool. [2]: 2248 It plays a crucial role in limiting climate changeby reducing the amount of carbon dioxide in the atmosphere. There are two main types of carbon sequestration: biologic (also called biosequestration) and geologic. [3]
Many people with chronic obstructive pulmonary disease have a low partial pressure of oxygen in the blood and high partial pressure of carbon dioxide.Treatment with supplemental oxygen may improve their well-being; alternatively, in some this can lead to the adverse effect of elevating the carbon dioxide content in the blood (hypercapnia) to levels that may become toxic.
Planting trees is a nature-based way to remove carbon dioxide from the atmosphere, however the effect may only be temporary in some cases. [1] [2]Carbon dioxide removal (CDR) is a process in which carbon dioxide (CO 2) is removed from the atmosphere by deliberate human activities and durably stored in geological, terrestrial, or ocean reservoirs, or in products.
Carbon capture and storage (CCS) is a process by which carbon dioxide (CO 2) from industrial installations is separated before it is released into the atmosphere, then transported to a long-term storage location. [ 1 ]: 2221 With CCS, the CO 2 is captured from a large point source, such as a natural gas processing plant and typically is stored ...
Obesity hypoventilation syndrome (OHS) is a condition in which severely overweight people fail to breathe rapidly or deeply enough, resulting in low oxygen levels and high blood carbon dioxide (CO 2) levels. The syndrome is often associated with obstructive sleep apnea (OSA), which causes periods of absent or reduced breathing in sleep ...
Climate change mitigation (or decarbonisation) is action to limit the greenhouse gases in the atmosphere that cause climate change. Climate change mitigation actions include conserving energy and replacing fossil fuels with clean energy sources. Secondary mitigation strategies include changes to land use and removing carbon dioxide (CO 2) from ...
The idea of net zero came out of research in the late 2000s into how the atmosphere, oceans and carbon cycle were reacting to CO 2 emissions. This research found that global warming will only stop if CO 2 emissions are reduced to net zero. [ 18 ] Net zero was basic to the goals of the Paris Agreement.
