Carbon Density and Change in Ecosystems

por Lela Mundy (2021-12-21)

The four channels in the Cascading Style Inventory (Cascading Projection-CSI) are named as "latent reservoir", "overhead", "inside reservoir" and "overhead along west coast". There are 16 nodes in the data set and these are distributed around the globe in the form of points, lines or boxes. The mean density of carbon is 6.6% along with corresponding uncertainties of about one percent. This project was initiated by the National Bureau of Standards (NBS) to improve the quality of the national inventory of soil and the condition of the soils across the US.

As part of the Global Change Impacts Research (GICE), a group of researchers led by Dr. Robert Kopp of the Cooperative Commonwealth Scientific Studies (CCS) headed by Dr. James S. Vose of James S. Vose & Associates Institute for Polar Science, led to analyze the global warming potential of the proposed changes in forest carbon density. They concluded that large scale changes in carbon dioxide concentration in the atmosphere may lead to drastic consequences on the global scale such as glacier retreat and consequent global warming. Their study was published in the renowned Journal of the Global Change Science (GOCE). Through this study, the scientists have established that the observed global warming since the mid-20th century is unprecedented, and it has been called 'carbon attribution' --the most accurate carbon footprint assessment.

Dr. Vose and his colleagues analyzed high carbon density sites across the US in the American Recovery Area (ARD). They found that although there are some isolated high carbon dense areas in the west and south central parts of the country, they are rapidly becoming remote due to warming air masses that can reach these locations in summertime. In the north-central parts of the country, the warming air masses can reach the high carbon density sites in the summer only. The conclusion drawn from the analysis is that although some of the carbon hotspots identified in the earlier studies have been eliminated, the overall effect on global temperature and climate is still worrying.

The researchers then conducted a series of field studies covering a large range of contrasting landforms with different climate and terrestrial conditions. To their surprise, they found that whereas in the high carbon density areas the ratio of species in the soil decreases with time, it actually increases in the lower areas. This implies that the warming air mass can melt some of the uppermost soil that leads to an increase in belowground biomass. Their studies showed that the changing atmospheric conditions, which lead to the atmospheric dynamics and metabolic processes, have profound effects on biomass and its distribution.

They concluded that these changes in the aboveground biomass and associated change in natural disturbance can disturb the dynamics of the regional and ecosystems functioning and consequently result in a rapid decrease in the natural carrying capacity of the plant. The results imply that biological productivity will decrease with time and will be substituted by the natural carbon carrying capacity of the soil.

The researchers explain that this process will likely aggravate the ongoing decline in the forests if no drastic actions are taken to arrest this process. They believe that future global warming will have severe repercussions on the global environment and therefore must be addressed seriously.

The study also showed that the reduction in natural vegetation can lead to increase in belowground biomass. It is alarming at how fast and rapidly the ecosystems can be impacted. These findings are alarming as deforestation leads to the release of harmful greenhouse gases into the atmosphere. Rapid degradation of natural vegetation and increase in belowground biomass carbon stocks are likely to increase pressure on already overstressed ecosystems and result in further fragmentation of ecosystems. The spatial expansion of bio carbon storage may result in increased spatial pressure on already remote and biologically rich terrestrial ecosystems with diverse habitats and living biomass.
