the second cause of global climate change is fluorocarbons. Fluorocarbons are man-made chemicals used in refrigerants, solvents, and anesthetics. These chemicals contribute to the greenhouse effect, warming the Earth. The amount of these gases in the atmosphere and their atmospheric concentration is lower than carbon dioxide but, they are a lot more potent. Even though the use of fluorocarbons has been phased out, they still exist inside of older equipment.
Throughout this report I will be speculating the importance on the advantages and disadvantages in the proceeding construction of the biggest dam in the world called the Three Gorges Dam. The dam is going to be built across the Yangtze River; this river runs from Shanghai and to Yibin. Also the Yangtze River is the third longest river in the whole world. First of all a dam is an artificial embankment or a barrier which helps control the pressure and speed of the water flowing through the river and also it prevents flooding from happening. Dam’s are also used to generate electricity.
Explain how you determined this. Pyrite hypothesis accept/reject = I would reject as there was no change. Coal hypothesis accept/reject = I would accept as ph was indeed higher Based on your data, what effect do you predict coal mining has on the environment? Answer = I would say coal mining increases acidity in the environment. What can be done to prevent mine drainage from damaging the ecosystem?
As this would affect not only the environmental issues- reformists realise this would then also affect the economy of the capitalist market. The key feature is that there are ‘limits to growth’ and that it is realised that environmental exhaustion will ultimately threaten economic performance and therefore reformists believe it is key that a path of sustainable development is followed. Reformists believe this will reduce the ‘tragedy of the commons’. Reformists believe development is good but it needs
Carbon dioxide does not only cause problems in the atmosphere but also in the ocean. The coming of industrial advancement has brought many changes in the earth’s environment (Gibson et al., 2011). Industrialization has brought an increase in gases released into the atmosphere; carbon dioxide forming the largest percentage. The ocean absorbs about 30% of the carbon dioxide in the atmosphere and, thus the increase of carbon dioxide in the atmosphere leads to a corresponding increase in the amounts the ocean absorbs. When the ocean absorbs carbon dioxide it reacts with water to produce chemicals such as bicarbonates and carbonic acid, which lowers the pH of the ocean.
EXECUTIVE SUMMARY: Maple Engery (U.S), a U.S.-based power plant provider, is evaluating the prospects for a project financing of the Tianjin Plastics power plant project in China in 1996. The proposed project financing agreement must ensure the financial viability of the project. In addition, the proposal must consider both the currency risk of potential RMB devaluation and the impact of substantial barriers to investing in China, including • Chinese government limited the target ROI between 15%-17%, while analyst estimated at least 18% was needed to adequate compensation for projects of this type. • Chinese government may refuse to guarantee fulfillment of a contract like this. This increased the project risk, hence the cost of borrowing.
Under this treaty the member countries commit themselves to reduce emission of the most dangerous anthropogenic greenhouse gasses into the atmosphere, namely: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), sulphur hexafluoride (SF6), and two groups of gases, hydro-fluorocarbons (HFCs) and per-fluorocarbons (PFCs). The Kyoto Protocol was adopted in Kyoto, Japan, on 11 December 1997 and came into effect on 16 February 2005. According to this treaty, the member countries must meet their obligations to reduce greenhouse gases emission primarily through national measures and “flexibility mechanism” offered by the protocol . These mechanisms are International Emissions Trading (IET), Clean Development Mechanism (CDM) and Joint Implementation . The IET allows Parties to trade their emissions certificates.
“greenhouse gases” are gases such as carbon dioxide (which makes up 50% of the atmosphere, methane and water. The greenhouse effect traps in heat, which keeps us warm. Examples that are comparable to this subject would be putting a cup on hot coffee or putting blankets on a cold person. These gases are being reflected by the ground and reverse the direction. Over the years greenhouse gases have exceeded the regular rate, having more nitride oxide and carbon dioxide in the atmosphere heats up the earth more rapidly and does not let heat escape.
Carbon dioxide, nitrous oxide, methane, choloro fluorocarbons, and tropospheric ozone are the major gases that help keep the earth at a constant temperature. . Carbon dioxide is the most important because it is responsible for fifty five percent of the change of the intensity of the earth’s greenhouse effect. The increase of these gases are a result of population growth, industrial development, the increase of cities, and the cutting down of forests. Although the greenhouse effect is important, the increase in all of these things create an unexpected rise in temperature for the ecosystem.
