Nowadays, global warming is a term that is widely used by everyone; however most people do not know what it means. Global warming is a phenomenon for which the average temperature of the earth’s atmosphere and the oceans is increasing because of the high concentration of carbon dioxide (CO2). The rise in CO2 in the earth atmosphere has been observed since the industrial revolution began and it is projected to continue rising. According to America's Climate Choices "The average temperature of the Earth’s surface increased by about 1.4 °F (0.8 °C) over the past 100 years, with about 1.0 °F (0.6 °C) of this warming occurring over just the past three decades" (2011). With that data we can figure out that the temperatures are increasing very fast in the last few decades which coincide with industrial growth due to the fact that the greenhouse gasses are generated by the combustion of fossil fuels and deforestation. As the Intergovernmental Panel on Climate Changes (IPCC) reported in 2007, a great number of scientists from all the most important industrialized countries think that global warming is caused by production of greenhouse gases that come from human activities, especially those activities that involve the burning of fossil fuels and deforestation. However, there are scientists, they are called skeptics, who think that global warming is not real, instead they think climate changes undergo in a normal trend through the earth history. While some skeptics could argue that global warming does not exist, the following information based on: human activities have produced an enormous amount of greenhouse gas emissions and the increasing of them in the last 200 years proves otherwise.
Some studies have demonstrated that the human ac...

Since measurements began in 1958 -- and it can be assumed to have been the case since the industrial revolution -- emission of carbon dioxide into the atmosphere has risen steadily as a result of the burning of fossil fuels (Quay, pp 2344). Although there is much argument over the implications of increasing carbon dioxide levels in the atmosphere, there are several points that almost all scientists would agree on: firstly, carbon dioxide acts to absorb radiated heat; if present in our atmosphere will do just that to some extent. Second, the concentration of carbon dioxide in our atmosphere is rising. Third, the temperature of the planet is rising - although the amount of this increase and the causes of this rise are subject to disagreement (Philander, pp 193).
Fossil fuels, such as coal and oil, are Carbon rich compounds, the combustion of which produces Carbon Dioxide, a pollutant and a greenhouse gas. A large amount of energy is released during this process, which is why the pollutants off products are tolerated. This process occurs constantly throughout the world, in power stations, vehicles and cooking ovens, leading to an immense volume of CO2 being released every second, 50% of which is absorbed by oceans (Oce...
Studying the global carbon cycle, or the exchange of carbon among the Earth’s atmosphere, lithosphere, hydrosphere, and biosphere, is important to understanding the Earth’s climate changes. One explanation for the long-term carbon cycle is offered by the BLAG spreading rate hypothesis, developed by Berner, Lasaga, and Garrels in 1983 to link plate tectonics to the changes in the atmospheric carbon dioxide concentration and global climate. The intent of this paper is to discuss the central ideas of the BLAG hypothesis and the evidence supporting or opposing these ideas.
Global warming is a scientific, political, and controversial topic. Some believe it is catastrophic, a slow moving killer hiding in the shadows. Others do not even think twice about it as they race by in a Hummer. Global warming is the gradual increase of temperature throughout different climates. It is caused by the greenhouse gas effect in which greenhouse gases, like methane and carbon dioxide, reflect sunlight back and forth. This reflected ultraviolet light bounces between the earth and the ozone layer and becomes trapped, resulting in a gradual rise of temperature. Over time, the slow rise of temperature causes new climates throughout the globe. The article “What Megablazes Tell Us About the Fiery Future of Climate Change” by Tim Dickinson

Over the last few years almost everyone has heard that the earth is warming. Also, almost everyone has heard the pleas to go green and reduce carbon emissions, led by former Vice-President Al Gore. Even though there is not a truly accurate definition of global warming it can be roughly defined as a rise in average global temperature according to Laurence Pringle’s book Global Warming Assessing the Greenhouse Threat (19). Global Warming Assessing the Greenhouse Threat also bring up that the average temperature data that scientist are using only goes back to 1860 giving scientists today only 150 years of temperature data. Also, with this current warming, even with humans contributing to the rising average global temperature, scientist today do not fully understand all the complexities of the atmosphere (Pringle 19-21). According to another book by Mr. Pringle, Global Warming the Threat of Earth’s Changing Climate, scientists predict global temperatures could rise from two to six degrees Celsius by 2050 (33). Despite these predictions historical and new information show that scientist are incorrect that global temperatures will forever continue to increase. Global warming and the rise in global temperatures is due to humans burning fossil fuels and overconsumption of products, as well as natural cycles changing slightly and other natural phenomenon; however, this warming will eventually lead to global cooling.
Carbon dioxide or CO2 is known to be one of a number of gases that are astonishingly transparent to the visible light that falls on the Earth from the Sun, but it absorb the infra-red radiation that emitted by the warm surface of our Earth, to prevents its loss into space. Moreover, CO2 has varied considerably and this affected the Earth’s temperature. Most common source of this CO2 is known as the fossil fuel. Fossil fuels are primarily coal, hydrocarbons, natural gas, or fuel oil that formed from the remains of the dead plants and also animals. The burning fossil fuel that has been created by humans is the largest source of emissions of the carbon dioxide.
The Climate Mapping and Prediction Project, or CLIMAP, was the first interdisciplinary effort to map previous global climates. It resulted in maps displaying the size and location of LGM ice sheets covering 25% of Earth’s land surface, and planet-wide lower surface ocean temperatures, with exceptions in the lower latitudes where some warming may have occurred. While this project was revolutionary for the field, some of its discoveries were met with skepticism. Other climate scientists felt that the mapping of ice sheets was inaccurate in regards to: their extent into relatively low latitudes, presence in certain marine areas, and their overall thickness. Further research proved these errors to be true to certain extents in some regions of the maps. Regardless, CLIMAP was a turning point for interdisciplinary data modeling, and their findings became the cornerstone of the field. In the 1980s, The Cooperative Holocene Mapping Project, or COHMAP, took a step forward from CLIMAP, and aimed to create more accurate mapping of climate ranging from the Last Glacial Maximum to present by drawing from combined data proxies including pollen levels and 14C records. They succeeded, and the accuracy and intricacy of LGM climate modeling has been improving ever since. Current papers, like the Last Glacial Maximum published in Science magazine
Global warming and global climate change is the study of future increases of temperature across the globe. Studying climate change refers to how the over- all climate will change such as the dry places getting dryer and the wet places getting wetter. Global climate is dependent on “the greenhouse effect a natural process that helps regulate temperature” (Easterling and Karl). In the past few centuries humans have had a monumental effect on increasing of greenhouse gases in the atmosphere. Climate change is result of the increase amount of the greenhouse gasses in the atmosphere such as methane, carbon dioxide, water vapor, nitrous oxide, and ozone. “Global temperature has rose approximately 1.4 degrees Fahrenheit over
In the nineteen-teens, as World War I raged across Europe, Milutin Milankovic, a Serbian astronomer and prisoner of war, was busy computing the gravitational force of planets like Jupiter on the Earth’s tilt and orbit. He had an idea that the amount of solar radiation that reaches higher latitudes could trigger an ice age or warm up the Earth. He believed that slow changes in the Earth’s orbit contributed to the amount of solar radiation reaching a particular latitude. By the end of the war, his first paper was published on the subject, and he began to expand upon his initial ideas. In 1941, he published Canon of Insolation of the Earth and Its Application to the Problem of the Ice Ages, describing his theories about the Earth’s orbit and tilt which are now referred to as the Milankovitch Cycles.
In theory some parts of the world might benefit, from a human point of view, due to global warming. However, at current rates of warming, local ecosystems will collapse and any objective measure of global benefits versus suffering would show much more suffering than benefits gained.
The emission of green house gasses due to human activity contributes the most in increasing global warming. Today, fossil fuels are used as a source of energy for transportation, electricity, industrial process and to increase human comfort in this era. Over the last decade humans have created mass amount of industries. These industries have been burning fossil fuels such as coal, which release carbon dioxide and carbon monoxide; carbon dioxide absorbs heat that raises the temperature of the earth. More than 80% of carbon dioxide comes from tr...
The emission of carbon dioxide has contributed to 80% to the heating of the earth atmosphere. Carbon dioxide is produced due the burning of fossil fuels such as natural gas, coal and oil. The burning of fossil fuel is very important in our society today, because it is used for cooking, used to produce electricity, for heating, for cooling and also for transportation. The industrialization has led to the use of fossil fuel for running machines and driving cars. The building of fossil fuel contributes towards 80-90% of the carbon dioxide we find in our atmosphere today. When the ecosystems are altered and vegetation is either burned or took out, the carbon stored in them is relinquished to the atmosphere as carbon dioxide (What causes global climate change, 2005). Methane is another gas being produced in the process which all have served to increase the greenhouse effect in our atmosphere. Methane is produced from the cultivation of rice, from the burning of coal and from cattle, it has increased by 145% due to human
