Global Warming


Climate change is neither new nor unusual. Throughout the history of the earth, the average surface temperature, climate and greenhouse gas concentrations have changed, sometimes gradually other times quite sharply. During the past 10,000 years the earth has been in an interglacial period with a fairly stable climate, surface temperature, and greenhouse gas concentration1. The problem that has arisen in recent times is when scientists analyze the past 150 years, especially the last 50. Scientists have found an increased greenhouse gas concentration, making the 20th century the hottest in the last 10,000 years.

Although the earth has undergone periodic changes known as global cooling and global warming, today’s global warming is unique, due to human influences. The greenhouse effect is essentially gasses in the atmosphere trapping heat, rather like a car window does in the summer. The major heat trapping gasses found in the atmosphere are; CO2 and water vapor- which are found in large quantity, 03(ozone), ch4(methane), and N2O(nitrous oxide)-which are better heat trappers but found in smaller quantity, CFC’s and PFC’s- which are very potent and destroy ozone. The rapid elevation of these gasses in the past fifty years have been the cause for concern of scientists calling it a global warming problem.

Global warming is a natural process as well as a human assisted process. Solar flares and sunspots along with natural elevation of greenhouse gasses due to volcanic activety are the natural causes for global warming. Dr. Judy Lean, a leading astrophysicist, looked at global warming trends from 1860 to the present day. Her research has found from 1860 to 1970, global warming was largely due to natural sources. But from 1970 to the present natural sources accounted for only one-third the increase while human influence accounted for the remaining two-thirds of the increased greenhouse effect.

The increase in greenhouse gasses from human sources comes from a variety of things. Elevated Co2 levels, which have been increasing at a rate of 0.5% per year, largely come from the burning of fossil fuels(70-75%), especially coal. Deforestation and plant burning account for the remainder. Increased Methane and Nitrous oxide in the atmosphere are mostly due to agriculture; rice patties, cattle, termites and decomposition of dead...

...ns in order to stop the increase. In order to slow the increase, the efficient use of fossil fuels must be adapted. Natural gas gives off very little co2 and methane if burned properly. Deforestation must also be stopped in order to give natural co2 scrubbers, plants, a chance to aid in the process. Governmental programs have also been implemented. A carbon tax has been considered along with the passing of the 1990 Clean Air Act, aimed at lowering emissions and cleaning air pollution. On a world wide scale, the Kyoto Accord in 1997, in which 159 nations agreed to work together to decrease Co2 emissions by 5.5% by 2012. The United States agreed, since it accounts for 25% of the worlds total emissions by 1990 figures, to cut its emissions by 7%.

Global warming is still a major issue in world and U.S. politics. Conservatives argue for more market-orientated solutions, resulting in the imposition of taxes, resulting in higher prices for environment polluting goods. Liberals on the other hand advocate stiffer industry regulation and more direct controls. Any action taken, whatever the ideology, can only help to solve an increasing problem but at what cost to the consumer?

Global Warming : A Global Problem Essay

- What is blue, green, and sustains an environment for living organisms to live. The answer is Earth; the planet of life where plants, animals, and humans breathe in the oxygen that comes from the atmosphere; knowing that we depend on oxygen to survive, preserving the atmosphere should be important enough to take care of it; sadly Earth is going through a global problem that is putting the atmosphere and the whole Earth in danger; that problem is called Global Warming. Global warming is used to describe increases in the average temperature of the Earth’s atmosphere and oceans; therefore this change is believed to be rapidly changing the Earth’s climate....   [tags: Global warming, Greenhouse gas, Carbon dioxide]

Global Warming Is A Global Issue Essay

- Many climate scientists, researchers, and environmentalists are expressing concerns about shifts in the overall climate of the earth. It is believed that a dramatically dangerous warming is taking place in the overall global climate, a problem that is referred to as "global warming”. Global warming is the observed century-scale rise in the average temperature of Earth’s climate system. This temperature rise is due to the damaging effects of deforestation and the burning of fossil fuels. It is our responsibility to preserve our planet and our way of living but in order to do that we need to act now....   [tags: Global warming, Carbon dioxide, Weather, Ocean]

Global Warming : A Global Issue Essay

- Climate change is undoubtedly one of the most pressing threats we face today. A global issue, it is not confined to any single neighborhood of the globe; our entire planet is threatened by this menace. The overwhelming scientific consensus is that humans are causing the climate to warm by emitting immense amounts of greenhouse gases into the atmosphere. Global warming threatens to melt the ice caps, raise sea levels, and increase the potency and frequency of severe weather events. If immediate action is not taken the situation will only continue to deteriorate....   [tags: Carbon dioxide, Global warming, Emissions trading]

Essay on The Pros and Cons of Global Warming

- The climate on the Earth is changing. Ice age is interleaved with the global warming. In the present age, the temperature of the Earth's climate system continue rapidly increase and it leads to global warming. Global warming is the process of gradual growth of average annual temperature of the atmosphere of the Earth and World ocean. The average temperature on the Earth was increased by 0.6C. There are various reasons of global warming, such as human activities, natural events, increasing of gases, such as carbon dioxide in atmosphere and solar activity (Global warming)....   [tags: Global Warming Essay]

Global Warming Essay

- Global Warming Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. (Melissa Phillips). This results in an increased emission of greenhouse gases. (Caroline Quatman). Short-wave solar radiation sinks into the Earth's atmosphere and warms its surface; while longwave infrared radiation emitted by earth's surface is absorbed, and then re-emitted by trace gases. (Brent C. Willhoite) Climate changes occur in our earth's atmosphere due to a buildup of greenhouse gases....   [tags: Environment Global Warming Climate Change]

Global Warming Essay

- Global Warming Global Warming is an important ecological issue and has many negative effects upon our environment. Global Warming, or what has been called the Greenhouse effect, is the result of a fourfold ecological process. 1-Sunlight radiates from the sun, through space, to Earth’s atmosphere. 2- The sunlight enters the atmosphere and hits Earth. Some of it turns into heat energy in the form of infrared light. The heat gets absorbed by surrounding air and land, which in turn makes it warm....   [tags: Environment Global Warming Climate Change]
