Green Gases


QUESTION 1: Technology owes Ecology an Apology. Indeed, in my opinion, technology does owe ecology an apology. This is because ecological imbalances were as a result of the Industrial revolution, which could be said to be the beginning of the non-ending technological advancement cycle. During Industrial revolution, we began altering or climate and environment through changing agricultural and industrial practices. Before the industrial revolution, human activity released very few gases into the atmosphere, but now through population growth fossil fuel burning and deforestation, we are affecting the mixture of gases in the air, which in turn affects all other species in the world. The water bodies have been major victims to, and have experienced the whims of technology. They have been used as dumping grounds for all toxic waste -- waste that is as a result of technological advancement. This has brought about the extinction of some species and has killed many types of marine species. In addition to this, the once beautiful beaches of the world have been scarred with waste. The natural water rivers no longer hold rich ecosystems as before as many of them cannot be able to survive in the harsh conditions. QUESTION 2: What do "anthropogenic greenhouse gases" mean? Discuss the anthropogenic greenhouse gases in terms of their potential to cause global warming. Anthropogenic greenhouse gases are those gases that are emitted into the atmosphere and have an adverse effect on the climate. These are gases that are as a result of human activities. Greenhouse gases are the gases trapped inside our atmosphere, which tend to keep the planet earth warm. These gases are carbon dioxide (CO2), water vapor (H2O), nitrous oxide (N2O),...

...thin the atmosphere before being chemically broken down for over a hundred years. There are no sinks for these greenhouse gases, so chemical reactions are the only way for them to disappear. The steps below show how they are broken down, and the destruction of ozone (O3) along with it. This also is a negative effect of CFCs when they destruct our ozone layer. Step 1 "Photolysis" (splitting by sunlight) of CFCs in the stratosphere Cl2CF2 + UV light --* ClCF2 + Cl Step 2 Catalytic destruction of ozone Cl + O3 --* ClO + O2 ClO + O3 --* Cl + 2O2

Climate Change: Global Emissions of Green House Gases Essay

- There are growing concerns about climate change and the effect of ‘greenhouse gases’ (GHG) on the gradual increase in world temperatures over time, now commonly known as global warming. The ‘greenhouse effect’ means that ‘greenhouse gases’ such as water vapour (H2O), carbon dioxide (CO2), methane, nitrous oxide, and fluorocarbons insulate the Earth by absorbing heat from the Earth’s surface and reflecting it back into the atmosphere, acting in a similar way to a thermal blanket (Houghton, 2005)....   [tags: Environment, Global Warming, Climate Change]

Essay on The IMO Debate in Relation to CO2 Emission Reductions from Ships

- 1. Introduction The human activities are continuing to affect the global climate by emission of Green House Gases (GHGs). Study shows that the temperature of the earth mean surface air has been increasing over 100 years. (IPCC, 2013) Although comparing with other industries or transports modes, shipping has relative small emission of Carbon dioxide (CO2), which is the most important GHG emission, the amount of CO2 emission is still in a high level, 1046 million tones and 3.3% of the global CO2 emissions in 2007.(IMO,2009) In the year 1992, 154 nations signed United Nations Framework Convention on Climate Change (UNFCCC), which became the basic framework of regulations on the reduction of G...   [tags: environment, green house gases]

Climate Changes and Human Development Essay

- INTRODUCTION With the advent of scientific and technological innovations, human beings have made tremendous industrial and economic successes. Nevertheless, climate change, characterized by the earth heated by from over-emitted green house gases, has been recognized as one of the most serious but inevitable consequences of human development. According to Crowley (2000), the combination of a unique level of temperature increase in the late 20th century and improved constraints on the role of natural variability provides further evidence that the greenhouse effect has already established itself above the level of natural variability in the climate system....   [tags: Green House Gases, Weather Change]

Protecting our Cities from Sea Level Rise Essays

- Imagine the world where all the ice of the poles has melted away. Much of northern Europe is a part of the Atlantic Ocean. Florida is completely submerged underwater.

The Kyoto Protocol: An Attempt to Manage Global Warming Essay

- The Kyoto protocol is one of the most important treaties signed in contemporary days. It has great limitations and is yet to evolve to another level, but it addresses an issue that affects not one, two or ten countries – it affects the entire world. That is why countries have to work and cooperate to create a binding legal document that sets specific standards to greenhouse gas emissions. In recent decades we have witnessed a gradual change in our environment. Our planet is heating up very quickly which leads to the so called global warming....   [tags: Environment Green House Gases Climate Change]

Global Warming and Greenhouse Gases Essays

- Global Warming and Greenhouse Gases The concentration of the atmosphere's main greenhouse gases specifically, carbon dioxide, methane, nitrous oxide, and water vapor, have increased significantly during the industrial age. These high concentrations are predicted to continue in the atmosphere for thousands of years to come. This increase in specially carbon dioxide, increases the infrared energy taken in by the atmosphere, and warming the earth's surface. The Global mean temperature over the past 150 years has risen between 0.3 degrees C and 0.6 degrees C....   [tags: Climate Change Environment Environmental]

Essay on Hydroelectric Reservoirs and Greenhouse Gases

- Introduction Water is essential to support life on Earth. Naturally rainfall is not evenly distributed by season or geographical region making water reservation a crucial component of water accessibility (Yuksel, 2010). Constructing a dam to reserve water is primarily used as storage for human consumption; which in modern times has been ameliorated to produce hydroelectricity and in some circumstances is used solely for hydropower (Gagnon and Van De Vate, 1997). An increasing demand for energy is putting strain on our natural resources and placing global warming at our front door....   [tags: Water, Life, Natural Resources, Global Warming]
