Carbon Sinks and Global Climate Change

In global climate change, carbon sinks are talking about. To understand this discussion, you must first understand what carbon sinks are and what they do. Plants have the natural ability to absorb carbon dioxide from the atmosphere and store it as carbon. Regarding global climate change, plants, especially trees, can help to absorb some of the carbon dioxide released by the body into the atmosphere. This has become a possible solution to mitigating climate change. As with many possible solutions to climate change, both positive and negative aspects of carbon sinks are mitigation options.

Healthy soil functions as a carbon sink, it stores large amounts of carbon and helps to delay global warming. However, as soil health is gradually consumed, these carbon sinks begin to evaporate. Plants absorb carbon dioxide in the atmosphere by photosynthesis, and when these plants decompose (processes assisted by microorganisms), they leave organic matter in soil and underground, leaving carbon in the soil to form carbon sinks. By increasing soil health, we can increase the possibility of carbon sequestration, thereby alleviating global climate change.

Soil organic matter works as a carbon source and may sink into climate changing biosphere. Using Parton and his colleague's "CENTURY" model, he simulated climate change and atmospheric CO2 concentration in 31 temperate areas and savanna areas, and in addition to the cold desert steps, CO2 is everywhere Reported that the production volume was increased. Climate change has resulted in an overall decline in carbon in the soil and the world's meadow decreased by 4 μg after 50 years. Climate change and the rise in CO 2 concentration increased the yield, the C loss in the world grassland decreased to 2 μg, and the savanna became a small sink of soil C. A similar impact was also observed in soil carbon loss reports in Australia's soil. Davidson and Janssens used the CENTURY 33 and ROTH - C 34 models to investigate the temperature sensitivity of soil carbon decomposition and fed back to the climate. What is the q theory of organic matter dynamics?

Because forests can function as carbon sinks, they play an important role in mitigating climate change. Otherwise it absorbs carbon dioxide which is released into the atmosphere and leads to a continuous change in climate pattern. Forest logging impairs this important carbon sinking function. It is estimated that 15% of the total greenhouse gas emissions are due to deforestation. Forest destruction is of particular concern in tropical rain forests, a habitat for many biodiversity in the world. For example, about 17% of the Amazon forest has been lost in the past 50 years. This is mainly due to the conversion from pasture to cattle meadow. Forest logging in this area is particularly prevalent in areas with high population near roads and rivers, but even when a valuable mahogany, gold or oil is discovered, even remote areas are infringed.
