Carbon sinks are found when there is a collection of carbon dioxide within a reservoir. Both, the terrestrial and aquatic systems, can act as natural carbon sinks, as can the atmosphere, where the collections of carbon dioxide as well as carbon dioxide emissions are high. The efficiency of these sinks has been declining since the 1990’s (Canadell et al. 2007). Approximately, 50% of carbon dioxide emissions are collected in the terrestrial and oceanic sinks (Ritschard 1992), which are detrimental to the ecosystem. Atmospheric carbon dioxide levels have been significantly small compared to the anthropogenic emissions when it comes to substantiality (Canadell et al. 2007). This is because the natural carbon sinks of the ocean remove some of the anthropogenic carbon dioxide (Canadell et al. 2007). Although the exact amount of carbon stored in these sinks cannot be determined due to lack of research, scientists do know that coastal ecosystems (or intertidal zones) are the most intense carbon sinks around (Vierros 2013). It is well known that carbon dioxide is a radioactive gas (Edmonds 1992). Carbon dioxide as well as the other radioactive gases such as ozone and water vapor, (Edmonds 1992) are the gases that become trapped in the atmosphere and are commonly referred to as greenhouse gases. There is approximately a 0.4% increase of the amount of carbon dioxide in the atmosphere a year (Ritschard 1992).
Carbon has been collecting in the oceans for many years. Because of the addition of human activity, much of the carbon dioxide that enters into oceanic and other aquatic systems comes from the terrestrial systems (Oswood et al. 1996). These sources include but are not limited to eroding peat, inorganic carbon, runoff and soil dissolved ...

Carbon Dioxide Is Essential For Life On Earth Essay

- Carbon dioxide (CO2) is produced either by natural sources, such as volcanic eruptions or human activities like deforestation that influence CO2 concentration levels. CO2 is essential for life on earth; therefore, it is important to regulate CO2 concentration levels derived from human activities. Further, the increases of CO2 exerted into the earth’s atmosphere for the past several thousand years are attributed to many CO2 sources induced by humans. CO2 Concentrations The Mauna Loa Observatory, with the support of Department of Energy, maintains data regarding CO2 atmospheric concentration measurements (The Keeling Curve, n.d.)....   [tags: Carbon dioxide, Global warming, Fossil fuel]

Carbon Dioxide Intake of Oceans Essay

- INTRODUCTION The level of carbon dioxide has increased tremendously over the past few years by nearly 40%, that is from approximately 280ppm in preindustrial times to 384ppm in 2007(Solomon et.al 2007). Nearly one third of anthropogenic carbon dioxide is being absorbed by the oceans today(Science Daily, May 24, 2008) . Uptake of carbon dioxide by the oceans is not a harmful phenomenon , but excess of it leads to a reduction in pH thereby altering the fundamental seawater chemistry, commonly known as ocean acidification ....   [tags: Dissolution Rates, Acidity]

Carbon Sinks and Global Climate Change Essay

- Carbon sinks have been a hot topic surrounding global climate change. To understand this debate it is first essential to understand what carbon sinks are and what they do. Plants have the natural ability to soak up carbon dioxide from atmosphere, storing it as carbon. In relation to global climate change, plants, especially trees, can help to absorb some of the carbon dioxide that humans have emitted into the atmosphere. This becomes one possible solution in mitigating climate change. As with many possible solutions to climate change, there are positive and negative sides of carbon sinks as a mitigation option....   [tags: Environment Earth Papers]

Essay on Analysis : Carbon Footprint Assessment

- 1. LITERATURE REVIEW Carbon footprint assessment Balancing the carbon emissions and keeping in pace with progressive growth is a challenge faced by developing economies like India. By 2030, the world’s population in cities will be consuming 73% of world energy, which accounts for 70% of CO2 emissions. Building construction and usage consumes one-third of the primary electricity in India (Agency, 2009). Embodied energy and carbon is also a topic of rising importance. In fact, it is normally possible to reduce the embodied energy and carbon of a building or construction project by 10-20% without adding to the build cost....   [tags: Greenhouse gas, Carbon dioxide]

Essay about Acidification Of The Oceans : Acidification

- Acidification of the Oceans Better known as the other CO2 problem; ocean acidification, is the increase in acidity of the oceans due to vast amounts of anthropogenic carbon dioxide being released into the atmosphere. An increase in the atmospheric carbon dioxide concentration is resulting in an increased the amount of carbon dioxide being dissolved into the oceans. The planet’s carbon sink currently absorbs around 1/3 of the carbon dioxide released into atmosphere, that’s 22 million tons of carbon dioxide being dissolved into our oceans every day....   [tags: Carbon dioxide, Bicarbonate, PH, Carbonate]

The Atmospheric Time Of Carbon Dioxide Essay

- When looking at the atmospheric residence time of GHGs in the IPCC Assessment Report (1996), we can find an interesting point--the lifetime of carbon dioxide is ‘‘variable’’, which can be as long as a century time-scale. Because of this feature, even if human beings stop emitting carbon dioxide into the atmosphere from now on, it will still take a long time for the earth to remove the extra carbon dioxide from the atmosphere, so the atmospheric temperature will keep going up for a long time. Therefore, the residence time of carbon dioxide is broadly used in analysing the future warming risks....   [tags: Carbon dioxide, Greenhouse gas, Global warming]

Carbon Dioxide And Its Effect On The Earth Essay

- Carbon dioxide is an important gas that is vital for plant life. This compound is made of a carbon atom and two oxygen atoms. Only 0.0397 of the atmosphere is composed of carbon dioxide. Even though carbon dioxide only makes up a small percentage of the atmosphere, lately increases in the amount carbon dioxide released into the atmosphere have shown to cause an adverse effect on the earth. The rise in amount of carbon dioxide in the atmosphere has caused the earth’s temperature to steadily rise....   [tags: Global warming, Carbon dioxide, Earth]

Essay about Ocean Acidification - What is Happening to Our Oceans

- Ocean acidification (OA) is defined as a reduction in ocean pH as a result of the absorption of anthropogenic carbon dioxide by surface waters (Hofmann et al. 2010). It is estimated that the oceans have become 30% more acidic since the beginning of the industrial revolution (Feely, 2004). • Significance of the impact of human activity and the associated change on the ocean o CO2 emissions from burning fossil fuels leading to increased uptake of CO2 by oceans-affecting marine life esp. organisms that use calcium carbonate to build shells, ocean is more acidic o Moderates climate change by absorbing CO2 but reverse impact on ocean • As a result of increasing CO2, commercial fisheries are now...   [tags: fisheries, carbon, coral reefs]

OCeans Essay example

- Two-thirds of our planet is covered with oceans. The Pacific, the Atlantic, the Indian, and the Artic are the world's major oceans. They were formed by a series of geological processes that continue to affect the Earth. Seven main parts, called lithospheric plates, make up the Earth's mantle layer and crust. The plates fit together millions of years ago, and are constantly moving (at a slow pace-like a fingernail grows) over a layer of squishy, soft rock called asthenosphere that lies beneath the crust....   [tags: essays research papers]
