Essays on Carbon Dioxide

Cell culture is an in-vitro technique of cultivating cells under controlled conditions and in sterile conditions. The technique was first developed by Ross Harrison in 1907. During the process of cell culture, the cells are detached from their tissue of origin and segregated from each other, either by mechanical or enzymatic means. The detached cells are then transferred before culturing them in cell culture plate or flask. The first generation of producing cell through this method is called primary cell culture. The cells from the primary culture are transferred to a new culture plate with a fresh medium to ...

The human race has harmed the very planet that they live on, through their activities, since the very start of civilization. Using the resources provided by nature to fulfill the needs of the human beings is not something that is the cause of concern, but the indirect intent of incriminating damage to the environment is what the main source of concern is. Some of the impacts of human activity involve the disruption of carbon cycle, the disruption of hydro (water) cycle, and the reduction of species diversity. The major impacts of human activity on the carbon cycle include the ...

Global warming refers to the phenomenon due to which the average global temperature rises by a few degrees over a specified period of time, or as the time passes. The concern that this raises is that if the temperature keeps on rising every few years or so, it is not hard to imagine what would be its effects to the global climate and environment over the next few decades. The rise of a few degrees in a few years is not much of an issue; however, if this rise is consistent, that is where the concern of most of ...

‘Institution’ Emphysema is an irreversible condition, wherein air spaces in the lungs are enlarged, specifically those beyond the terminal bronchioles and most notably in the alveoli resulting in alveolar wall damage and airflow obstruction. This is most common among chronic smokers. (Braun, 2007) The development of an inflammation in the small airways is mainly the source of obstruction. In moderate to severe emphysema, the primary cause of obstruction is the loss of elastic recoil in the alveoli. Along with the airway obstruction, vascular changes in the lungs can be noted that will make the lining of the arteries and ...

Introduction

The issue of global warming has recently become more contentious. Ideally, a great debate exists among numerous individuals on whether it is real. According to MacMillan (Par. 1), the average global temperature over the past fifty years has risen at the most rapid rate in recorded history. In essence, the climate scientists connect the warming of the oceans and atmosphere, a strong decrease in the sea ice, and ocean level rise, among other climate-associated changes to the rise in the global temperature. The greenhouse gasses including carbon dioxide, water vapor, methane, and nitrous oxide contribute to global warming by ...

It is a big debate as to whether global warming is natural or caused by debilitating human activities. With literature demonstrating both sets of opinions with strong arguments, boiling down to a conclusion seems a harder haul. Still, this paper explores the reasons to highlight that global warming does have a natural cause, but it's too small compared to anthropogenic activities. Clearly, the world has witnessed rapid warming in the last decade, and a fleet of surface instruments and satellites have recorded a host of signs that pinpoint catastrophic actions by humans. The clear outcome of these activities in ...

The videos are about the demonstration of a small-scale greenhouse effect. They used carbon dioxide and methane to demonstrate that when these greenhouse gases are in higher concentration, it could increase the atmospheric temperature. In these experiments, the results show that when carbon dioxide and methane are added to the normal air condition, the increase in temperature due to the lamp is higher. This is considered as a laboratory-scale evidence of the greenhouse effect which is occurring in global scale. The results demonstrated in the experiments are new to me. I already knew that greenhouse gases are the main ...

Energy has played an important role in building the world economy today. From enabling man to perform daily activities to enhancing the functioning of many industries, it is sensible to state that energy is of great importance to the world. Due to its importance, fossil fuels such as coal have thus been burnt down to create energy. However, different negative effects are associated with burning such fuels to the environment. For instance, global warming gasses are emitted thus, causing global warming as a result of carbon monoxide, which is emitted while burning coal. Despite their disparities, both developed and ...

Effectiveness of Carbon Tax as Environment Policy

Climate change has emerged as a global challenge because unrestrained rising of global temperature would cause melting of glaciers and rise of sea level that would submerge land masses, change weather patterns with frequent incidence of hurricanes and floods and droughts. As an effective response to the challenge, global leaders have agreed to cut back emission of Green House Gases (GTG) to contain the global rise in temperature below 2 degree Celsius (Symon, 2013). Carbon dioxide, a major constituent of GTG, is released to the atmosphere on combustion of fossil fuels such as coal, oil, and ...

Abstract

Carbon capture is an essential approach for reducing greenhouse gas emissions. Different plants utilize various technologies in reducing carbon dioxide emission. Some of the conventional techniques employed include oxy-fuel, pre, and post-combustion carbon capture. These approaches have a high potential for capturing carbon dioxide. However, their massive initial and implementation costs have been a challenge to plants globally. Additionally, most of them are yet to experience large scale applications. Therefore, it is essential for research and development activities to be conducted. This can ensure a reduction in the cost of production. The carbon capture technologies differ in costs. This ...

Coal is a very cheap and abundant provision of energ. In fact, it is the most abundant fuel in the United States; U.S. has the highest coal reserve in the world, with up to 25% of the known world coal present in America and being mined in 26 out of the U.S. 50 states (fe.doe.gov, 2013). However, this abundant energy is seldom used because it is a very dirty energy. According to Hong & Slatick (1994), up to 204.3 pounds of carbon dioxide per million Btu is emitted when coal having 78% carbon content is completely burned to attain a ...

Abstract

The concentration of carbon dioxide has been abnormally increasing over the years. In the year 2016, its concentration exceeded the limitations, and has been considered as a dangerous situation. As a response to the increasing carbon dioxide content in the Earth’s atmosphere, different processes are being suggested in order to lower the concentration. Carbon Capture and Storage, or CCS, is one of these processes. Generally, there are three different phases of this process: the pre-combustion, the oxyfuel, and the post-combustion. These three phases have different processes in which the carbon dioxide content is being separated from the other ...
