North American Carbon Program CH. Support long-term quantitative measurements of fluxes, sources, and sinks of atmospheric CO and CH, and develop forecasts for future trends. The North American Carbon Program was designed to help with the process of providing data needed to model the synthesis activities. The carbon cycle is subdivided into two sections, the rapid carbon exchange, and long-term cycling of carbon through the various geological processes. This carbon cycle occurs in our biological processes, including respiration, photosynthesis, and is generated by autotrophs. Autotrophs (usually photosynthetic) are plants or algae, which capture the carbon dioxide from the air. In water, the compounds removed
Carbon dioxide removal to the biosphere. This process could be undone, for example by wildfires or logging. Carbon dioxide sinks that store carbon dioxide in the Earth's crust by injecting it into the subsurface, or in the form of insoluble carbonate salts (mineral sequestration), are considered carbon negative. This is because they are removing carbon from the atmosphere and sequestering it indefinitely and presumably for a considerable duration (thousands to millions of years). However, Carbon Capture technology remains, at best, theoretical and is yet to reach more than 33% efficiency. Furthermore, this process could be rapidly undone, for example by earthquakes or mining.
