Blue Carbon

Blue carbon is the term for carbon captured by the world's body of water and coastal ecosystems. Sea grasses, mangroves, salt marshes, and other systems along our declension are very efficient in storing CO2. These areas also absorb and shop carbon at a much faster rate than other areas, such as forests, and can proceed to do so for millions of years. The carbon plant in coastal soil is oft thousands of years one-time. When these systems are damaged or disrupted by man activeness, an enormous amount of carbon is emitted dorsum into the temper, contributing to climatic change.

Carbon is the foundation of all life on Globe, required to form circuitous molecules similar proteins and DNA. This element is also found in our atmosphere in the grade of carbon dioxide (CO2). Carbon helps to regulate the Earth'due south temperature, makes all life possible, is a cardinal ingredient in the nutrient that sustains us, and provides a major source of the energy to fuel our global economy.

The carbon bicycle describes the process in which carbon atoms continually travel from the atmosphere to the Globe so back into the temper. Since our planet and its atmosphere class a closed environment, the amount of carbon in this arrangement does not change. Where the carbon is located — in the atmosphere or on Earth — is constantly in flux.

On Earth, most carbon is stored in rocks and sediments, while the residuum is located in the ocean, atmosphere, and in living organisms. These are the reservoirs, or sinks, through which carbon cycles.

Carbon is released dorsum into the atmosphere when organisms dice, volcanoes erupt, fires blaze, fossil fuels are burned, and through a variety of other mechanisms.

In the case of the ocean, carbon is continually exchanged between the bounding main'south surface waters and the atmosphere, or is stored for long periods of fourth dimension in the ocean depths.

Humans play a major office in the carbon cycle through activities such as the burning of fossil fuels or state evolution. As a consequence, the amount of carbon dioxide in the atmosphere is chop-chop rising; it is already considerably greater than at whatsoever time in the concluding 800,000 years.

What is the carbon cycle? Carbon is the chemic backbone of all life on Earth. All of the carbon we currently have on Earth is the same amount nosotros have e'er had. When new life is formed, carbon forms key molecules like poly peptide and DNA. Information technology's also plant in our temper in the form of carbon dioxide or CO2. The carbon cycle is nature's mode of reusing carbon atoms, which travel from the atmosphere into organisms in the Globe then back into the temper over and over again. Most carbon is stored in rocks and sediments, while the residual is stored in the ocean, temper, and living organisms. These are the reservoirs, or sinks, through which carbon cycles. The sea is a behemothic carbon sink that absorbs carbon. Marine organisms from marsh plants to fish, from seaweed to birds, as well produce carbon through living and dying. Sometimes dead organisms go fossil fuels that become through combustion, giving off CO2, and the wheel continues.
