Since the industrial revolution, scientists have documented a trend of increasing atmospheric carbon dioxide (CO2), the main greenhouse gas. This observation has been an issue of major environmental concern in the view of the potentially devastating effects of climate change on ecosystems and human survival. Recent studies by scientists led by Wei-Jun Cai have served to underscore this fact by showing that the Arctic region and the globe are faced with a major climate challenge due to the continued melting of sea ice in the Arctic Ocean. This research has indicated that the major concern is the increasing heat absorption as deeper ocean water layers get exposed to sunlight as well as the possible loss of white ice reflectivity or the albedo (An Ice-Free Arctic Ocean Will Not Absorb More CO2, n.d).This paper discusses the recent observations that Arctic Ocean basin do not have an indefinite ability to continue acting as a CO2 sink when conditions are ice-free caused by the escalating warmer temperatures.
It is worth noting that sensitivity to climate changes in the Arctic is considered the highest on the Earth’s surface. In addition, the region experiences more pronounced acidification than any other ocean. Recent decades have seen the Arctic Ocean experience a steady increase in the rate of sea ice melt. According to Cai, et al. (2010), this has been especially so in the light of the indications of the three summers from 2007 to 2009. The recent research by Cai et al. has been built on the postulation that more and more CO2 would be absorbed from the atmosphere under ice-free conditions in the Arctic Ocean. Therefore, the research investigates the impact of sea ice melt on the concentration of CO2 on the surface water of the Ar...

...temperatures will continue causing ice melt in summer. Consequently, the surface water carbon dioxide partial pressure will continue to increase, further reducing the ability of the CO2 sink to take up more CO2. The high-resolution survey further points to the fact that the future will see an increased air-sea CO2 flux. This is due to the exposure of more area of sea water as well as long periods when the Arctic Ocean surface will be subjected to ice-free conditions. Though this is expected, the capacity of the CO2 sink in the Arctic Ocean to continue taking up CO2 is predicted to weaken due to equilibration of pCO2 of surface water with the atmosphere. The survey highlights four major factors which facilitate this equilibrium. These include low CO2 fixation, surface warming, shallow mixed-layer depth, and strong stratification of surface water (Cai, et al., 2010).

- Climate change or colloquially known as global warming, now pose a new threat to civilization as the levels of greenhouse gases (GHG) are soaring to new levels. The most significant contributor to greenhouse gasses would be Carbon Dioxide (Co2). The levels of Carbon Dioxide (Co2) gas have risen to levels civilization has not seen before. As such, the effects of these levels are not known to civilization as data gathered from the ice cores drilled in the Antarctica only shows data up to 650,000 years ago....

- When discussing the topic of climate change, it is essential to begin with a brief definition of climate change to know exactly what it is. Anup Shah of globalissues.org defines climate change as “an increase in average global temperatures…caused by the increase in greenhouse gasses such as Carbon Dioxide, or CO2” (Shah, 2014). This process, of course, is global warming which, in turn, leads to climate change. Although climate change is considered one of the most significant threats facing the world today, there are many groups doing what they can to assist in slowing the climate change process or potentially halt it all together....

- CO2 and greenhouse gas emissions are at an all-time high. In May 2013, the levels of carbon dioxide in the atmosphere exceeded 400 parts per million. This is “approaching the halfway mark between preindustrial amounts and a doubling of those levels” (Washington Post J). This is a very large increase in the amount of CO2 in our atmosphere over a short period of time. One might ask what consequence could come of having such a large volume of CO2 floating around our atmosphere. The Union of Concerned Scientists says that CO2 is considered a greenhouse gas....

- ... In addition to this, climate adaptations can also involve significant co-benefits or even trade-offs depending on the type of adaptation, and the location it is implemented (IPCC, 2014). Effective implementation of adaptation would focus on sustaining agriculture, biodiversity, coastal and water resource managements sectors (IPCC, 2014). The goals of these adaptation options aim to maintain current levels of success in these sectors, using technological control, economic funding and political powers to solve the relevant problems (IPCC, 2014)....

Seasons are shifting, temperature and sea levels are rising, meanwhile our only planet we can live on must supply us, animals, and other living organisms with food, water, shelter, and oxygen. If our country and others don’t come together and devise a method to begin with the help towards climate change our grandkids and future generations won’t be able to live like we do today. Not only are humans are impacted by global warming, but the wildlife is too.... [tags: Global warming, Climate change, Carbon dioxide]

- “It’s a well-kept secret, but 95 percent of the climate models we are told prove the link between human CO2 emissions and catastrophic global warming have been found, after nearly two decades of temperature stasis, to be in error,” writes Maurice Newman, chief business advisor to Australian Prime Minister Tony Abbott (Dunn). With this bold and senseless declaration, Australia joined the community of global warming denial and thrust itself onto the international stage to become yet another participant in the dramatic environmental debate about climate change....

- ... Regulations did not bind developing countries to reduce their emissions. Developing countries did not have all the resources to produce a clean, environmental energy system. On the other hand, industrialized nations would be forced to reduce their businesses and focus on developing clean energy. As mentioned by Jason, the Bush Administration announced its opposition to Kyoto in 2001 (Shogren, 2004). Their opposition rested on the fact that compliance costs would be excessive without the participation of the developing countries.... [tags: Greenhouse gas, Climate change, Kyoto Protocol]

- ... Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2. To a lesser extent, the clearing of land for agriculture, industry, and other human activities have increased concentrations of greenhouse gases” Humans, by constantly burning fossil fuels, are increasing the amount of carbon within the atmosphere, which in turn will make Earth’s temperature increase....

- Ethics on Global Warming Global warming and global climate change is the study of future increases of temperature across the globe. Studying climate change refers to how the over- all climate will change such as the dry places getting dryer and the wet places getting wetter. Global climate is dependent on “the greenhouse effect a natural process that helps regulate temperature” (Easterling and Karl). In the past few centuries humans have had a monumental effect on increasing of greenhouse gases in the atmosphere.... [tags: Greenhouse gas, Climate change, Carbon dioxide]

What Factors Control Carbon Mineralization and Flux in Bog Soils and How Would These Soils Respond to Global Climate Change?
- I. Introduction: What is a Bog. The word "bog," from the old Gaelic "bogach," is commonly used to refer to any stretch of waterlogged, swampy ground. The words, fen, moor, muskeg, peatland, and mire are also used to describe these areas, which can lead to some confusion over terminology. Specifically, a bog is "a peat accumulating wetland that has no significant inflows or outflows and supports acidophilic mosses, particularly sphagnum" (Gosselink and Mitsch 1993). The vast majority of bogs are located in the moist, cool boreal regions of North America and Eurasia.... [tags: Climate Bog Ecology Papers]
