upwellings
the upward movement of ocean water toward the surface as the result of diverging currents
carbon sequestation
the removal and storage of carbon from the atmosphere in carbon sinks (such as oceans, forests or soils) through biochemical processes.
halons
A compound’s ability to destroy ozone depends on many factors, including the amount of chlorine and/or bromine that it contains. To aid in comparing compounds, scientists have developed a relative scale called the ozone depletion potential (ODP). Common refrigerants, like those found in refrigerators and in automobile air conditioners, have been assigned the value 1 as a reference.
carbon tetrachloride
It was formerly widely used in fire extinguishers, as a precursor to refrigerants, and as a cleaning agent.
