Global warming is one of the most critical issues the world is facing in the twenty-first century, one that will affect every living creature on the planet. It is also an extraordinarily complex problem, which everyone needs to understand as clearly and completely as possible. The climate of the earth is constantly changing due to a variety of factors. These factors include, among others, changes in the earth’s orbit, changes in the sun’s intensity, changes in the ocean currents, volcanic emissions, and changes in greenhouse gas concentrations. The temperature of the earth is controlled by the balance between the input from energy of the sun and the loss of that back into space. Certain atmospheric gases are critical to this temperature balance and are known as greenhouse gases. The two most important greenhouse gases are carbon dioxide and water vapour. Currently, carbon dioxide accounts for 0.03-0.04 percent of the atmosphere, while water vapour varies from 0-2 percent. Over the past 150 years, the amount of carbon in the atmosphere has increased by 30 percent. Most scientists believe that there is a direct relationship between increased levels of carbon dioxide in the atmosphere and the rising global temperatures. One proposed method to reduce atmospheric carbon dioxide is to increase the global storage of carbon in terrestrial systems. An environmental component that absorbs and stores carbon for an indefinite period of time is known as the carbon sink, for example, forests and soils. The one that is discharging or emitting carbon is known as the carbon source, for example, volcanic eruptions and industrial emissions. The flow of carbon from one stock to another (carbon fluxes) involves various physical and biological processes e.g. fossil fuel combustion and biological growth. Most scientists believe that there is a direct relationship between increased levels of carbon dioxide in the atmosphere and the rising global temperatures Terrestrial carbon sequestration is the process through which CO2 from the atmosphere is absorbed by trees, plants and crops through photosynthesis, and stored as carbon in biomass (tree trunks, branches, foliage and roots) and soils (USEPA 2017). In the terrestrial system, carbon is sequestered in rocks and sediments, in swamps, wetlands and forests, and in the soils of forests, grasslands and agriculture. About two-thirds of the globe’s terrestrial carbon, exclusive of that sequestered in rocks and sediments, is located in the standing forests, forest under story plants, leaf and forest debris, and in forest soils. In addition, there are some non-natural stocks. For example, long-lived wood products and waste dumps constitute a separate human-created carbon stock. Given increased global timber harvests and manufactured wood products over the past several decades, these carbon stocks are likely increasing as the carbon sequestered in long-lived wood products and waste dumps are probably expanding. In contrast to many plants and agricultural crops, which have short lifespans or release much of their carbon seasonally, forest biomass stores carbon over decades and centuries. Moreover, carbon accumulation potential in forests is large enough that forests offer the likelihood of sequestering significant amounts of additional carbon in relatively shorter time periods. On the other hand, forest carbon can also be released rapidly, as in forest burning. Unexpectedly, forests managed for timber, flora and fauna or for ecological restoration stocks carbon through sequestration as a by-product phenomenon. Forests may also be managed specifically for sequestration purpose. But this could reduce the expanse of other forest ecosystem services such as biodiversity. Yet, if forests managed for carbon sequestration are allowed to reach maturity, one of the long-term impacts may be enhanced biodiversity.
