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 need atmospheric reduction of 50 ppm plus an additional 2 ppm per year of current emissions. Carbon dioxide removal is different from reducing emissions, as the former produces an outlet of carbon dioxide from Earth's atmosphere, whereas the latter decreases the inlet of carbon dioxide to the atmosphere. Both have the same net effect, but for achieving carbon dioxide concentration levels below present levels, carbon dioxide removal is critical. Also for meeting higher concentration levels, carbon dioxide removal is increasingly considered to be crucial as it provides the only possibility to fill the gap between needed reductions to meet mitigation
