CO2Bestände

CO2Bestände refers to the reserves or accumulations of carbon dioxide (CO2) in various natural and artificial reservoirs on Earth. These reservoirs play a crucial role in the global carbon cycle and have implications for climate change.

Natural CO2Bestände include the atmosphere, oceans, terrestrial biosphere (forests, soils, vegetation), and geological formations. The atmosphere holds a significant amount of CO2, which acts as a greenhouse gas. The oceans are a vast sink for CO2, absorbing it from the atmosphere and storing it in dissolved form, as well as in marine organisms and sediments. Terrestrial ecosystems sequester CO2 through photosynthesis and store it in biomass and soil organic matter. Geological reservoirs, such as underground rock formations and fossil fuel deposits, hold CO2 over long geological timescales.

Human activities, primarily the burning of fossil fuels and deforestation, have led to an increase in atmospheric CO2 concentrations, disrupting the natural balance of these CO2Bestände. This imbalance is a primary driver of anthropogenic climate change.

In the context of climate change mitigation, the concept of CO2Bestände also relates to carbon capture and storage (CCS) technologies. CCS aims to capture CO2 emissions from industrial sources and store them in underground geological formations, effectively creating artificial CO2Bestände. The management and monitoring of these anthropogenic CO2Bestände are critical for the effectiveness and safety of such climate mitigation strategies. Understanding the dynamics and capacity of natural and artificial CO2Bestände is fundamental to addressing the challenges of climate change.
