In more formal usage, parenthesis may refer to the entire bracketed text, not just to the punctuation marks used (so all the text in this set of round brackets may be said to be a parenthesis, a parenthetical, or a parenthetical phrase).
Carbon sequestration is the process involved in carbon capture and the long-term storage of atmospheric carbon dioxide (CO 2). Carbon sequestration describes long-term storage of carbon dioxide or other forms of carbon to either mitigate or defer global warming and avoid dangerous climate change.
There are three different types of sequestration. Oceanic sequestration stores carbon dioxide at the bottom of the ocean; terrestrial sequestration stores carbon in soils, crops, and other plants; while geological sequestration stores carbon underground in coal seams, saline reservoirs and oil reservoirs.
