Further uncertainties, especially regarding the persistence of the present terrestrial removal processes (carbon sinks) and the magnitude of the climate feedback on the terrestrial Support biosphere, cause a variation of about -10 to + 30 % in the year 2100 concentration, around each scenario.

The more active carbon storage areas within the Earth 's ecosystem are the living Activity terrestrial Support biosphere, the atmosphere and the oceans. [ 5CANADAICC 0 MG MCLH 26/03/2016 ]

The role of the terrestrial Support biosphere in global climatic change has been simulated using relatively simple models of vegetation on a global grid with a resolution as fine as 0.5 ° latitude x 0.5 ° longitude (SAR WGI: Section 9.4). [ 10IPCCMODELE 0 MG MCLH 26/03/2016 ]

Climatic changes during recent decades could also be causing the terrestrial Support biosphere to absorb a significant amount of carbon (SAR WGI: Sections 2.1.1 and 9.2.3.1). [ 10IPCCMODELE 0 MG MCLH 26/03/2016 ]

Examples include significant slowing of the ocean circulation that transports warm water to the North Atlantic, large reductions in the Greenland and West Antarctic Ice Sheets, accelerated global warming due to carbon cycle feedbacks in the terrestrial Support biosphere, and releases of terrestrial carbon from permafrost regions and methane from hydrates in coastal sediments.
