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.It has been proposed as a way to slow the atmospheric and marine accumulation of greenhouse gases, which are released by burning fossil fuels.iosequestration or carbon sequestration through biological processes affects the global carbon cycle. Examples include major climatic fluctuations, such as the Azolla event, which created the current Arctic climate.
Budget sequestration. Budget sequestration is a procedure in United States law that limits the size of the federal budget. Sequestration involves setting a hard cap on the amount of government spending within broadly defined categories; if Congress enacts annual appropriations legislation that exceeds these caps, an across-the-board spending cut is automatically imposed on these categories, affecting all departments and programs by an equal percentage.
