The causes of Global Warming

Causes of Global Warming

Human activities have a greater impact on the environment. The selfish acts of humans who do not care about the environment and the humans who really try to take care of the environment have to pay the price. People's aim is to achieve their goals, no matter what happens to the environment. The selfish nature of humans is the main reason for global warming. The world is undoubtedly warming. This is largely the result of emissions of carbon dioxide and other greenhouse gases from human activities including industrial processes, fossil fuel combustion, deforestation, etc. Continuation of greenhouse gas emissions will result in additional warming over the 21st century, rise in sea-level that will gradually inundate coastal areas, changes in precipitation patterns, risk of droughts and floods, threats to biodiversity, and a number of potential challenges for public health.

Carbon Dioxide
In 2002 about 40% of U.S. carbon dioxide emissions stem from the burning of fossil fuels for the purpose of electricity generation. Coal accounts for 93 percent of the emissions from the electric utility industry.

Natural gas gives off 50% of the carbon dioxide, the major greenhouse gas, released by coal and 25% less carbon dioxide than oil, for the same amount of energy produced. Coal contains about 80 percent more carbon per unit of energy than gas does, and oil contains about 40 percent more Carbon dioxide is emitted from power plants, cars, trucks, airplanes and buildings

The Effects of Global Warming

Effects of Global Warming

o Greenhouse gases in the atmosphere act like a mirror and reflect back to the Earth a part of the heat radiation. Global warming has no possible benefits. The predicted effects for the environment and for human life are numerous and varied. The main effect is an increasing global average temperature. World temperatures could rise by between 1.1 and 6.4 °C during the 21st century. This result in rise in sea levels, altered patterns of agriculture, increased extreme weather events, and the expansion of the range of tropical diseases. Its effect could be irreversible changes in the climate. There will be more frequent warm spells, heat waves and heavy rainfall. There will be an increase in droughts, tropical cyclones and

o extreme high tides.

o Increased Global Temperature

Increasing global temperatures are causing a broad range of changes. Sea levels are rising due to thermal expansion of the ocean, in addition to melting of land ice. Amounts and patterns of precipitation are changing. The total annual power of hurricanes has already increased markedly since 1975 because their average intensity and average duration have increased.

Changes in temperature and precipitation patterns increase the frequency, duration, and intensity of other extreme weather events, such as floods, droughts, heat waves, and tornadoes. As a further effect of global warming, diseases like malaria are returning into areas where they have been eradicated earlier.

The Global Warming in the UAE

Global Warming in the UAE

There is a steep rise in temperature in the UAE this year. There was a lot of precipitation this year (2007) compared to previous years. A report released Aug. 3, 2006 by the Emirates News Agency highlights the dangers caused by global warming to many low-lying Middle Eastern countries, including the United Arab Emirates (UAE). The two most severe problems are desertification and dangerously high sea levels, which could rise by as much as 2.89 feet in this century. According to Sheikh Hamdan Nahyan, deputy chairman of the UAE's Environmental Research and Wildlife Development Agency, "This can flood not only coastal areas of the United Arab Emirates, but also much of the heavily populated Nile Delta in Egypt.

The individual Action

Individual Action

If you increase your personal petrol or gas consumption for this year by say 1'000 liters because you use the car more often, will this lead to natural disasters? And if yes, where ? Nobody will be able to take you to the court, because it is not possible to prove a direct relation between your increased yearly consumption of fuels and a drought in Africa. This does not change the fact, however, that the CO2 emission produced by your car does indeed contribute to the global warming. No doubt, you and I are responsible for the climate change, too.

The summary

Summary

We are indeed fully responsible for everything we do or do not do! The fact that we don't get fined or taken into prison for certain deeds does by far not mean that these deeds do not have a big impact on our personal future life. The goal of all human beings is to live in joy and perpetual harmony with oneself and with the environment, to be able to enjoy life free of sorrows and fears. The selfish nature of humans to profit for themselves will bring their own destruction; it is high time now, we have to act fast. We have to try to find other sources of energy such as wind, wave and solar energy. Deeds are more important than words - do start now!
