Heat And Global Climatic Change

In the last 100 years, the amount of greenhouse gases in the atmosphere has increased, causing the Earth to warm by an average of 0.6 degrees celsius, largely a result of burning fossil fuels for energy, transportation, and land use changes increased for food production. The basic science is straightforward and climate researchers have shown that gases such as carbon dioxide, methane and others can trap heat in the Earth’s atmosphere, causing a phenomenon known as the greenhouse effect. Human activities such as industry, transport, energy generation and deforestation all produce these greenhouse gases. In the last 20 years, concern has grown that global warming is inevitable and now considered most probably caused by man-made increases in

a. We have been influencing climate change for some time now. Through the industrial revolution, a growth in the size of the population, and our daily activities, are releasing green house gases. Green house gases affect the earth by, absorbing the reflection of sunlight once it hits the earth. This causes the atmosphere, the oceans, and the surface of the land to warm up.

The Global Warming theory has become increasingly popular over the past few years. Citizens of the world are being encouraged to be more environmentally conscious by others including politicians, celebrities, and world organizations. The problem with the theory lies in the fact that it has become more and more controversial as it gains publicity and attention. The basic concept behind this theory is that the earth was made with a balance of “greenhouse gasses”. These gasses are naturally occurring within the atmosphere and they essentially make the planet habitable by keeping it warm.

Our lives involve the emission of theses dangerous greenhouse gases (Bushnell 25). Carbon dioxide has increased to

Some might argue that the Green House Effect is needed because it allows the earth to trap greenhouse gasses in the atmosphere, which are needed in order for the earth to stay warm and avoid extremes; however, it has never resulted in year that has been labeled to be the “hottest year on record” (Rampell). Some argue that it’s just a part of the natural process the has been occurring since the beginning of time, the earth warms up and cools off it happens. However, not at such an alarming rates NASA has been looking at records that indicate that the “warming trend over the last 50 years” is “nearly twice that for the last 100 years”. Meaning the earth is warmer today than it was 100 years ago. The larger the amount of carbon dioxide, one of the greenhouse gasses, that is in the atmosphere the warmer the earth becomes (Talking to Children about Climate Change).

Since 1975, the surface of the earth 's average temperature has risen by 0.9 degrees Fahrenheit; global warming caused by greenhouse effect has become the focus topic of the world. It has long been recognized academically that due to the burning of coal, oil, natural gas and so on the carbon dioxide is the main culprit of global warming. I watched a documentary, which called “The Great Global Warming Swindle.” In the documentary, the scientists pointed out that there is no direct evidence that carbon dioxide is the cause of global warming, global warming is more of propaganda, a kind of political activity. Normally, as an amateur people, should write this article emphasizes their neutrality, but actually, I agree with BBC.

Climate change is influenced by the greenhouse effect which is the increase of Carbon dioxide, Methane, Ozone and Nitrogen Oxide. On one hand, the presence of these gases in the atmosphere make the earth habitable with respect to regulating the earth’s temperature. However, an increase in the concentration of these gases results in trapping energy in the atmosphere and this in turn increases earth’s temperature. “Global greenhouse gas emissions have grown since pre-industrial times, with an increase of 70% between

The Global Warming theory has become increasingly popular over the past few years.

The problem with the theory lies in the fact that it has become more and more controversial as it gains publicity and attention. The basic concept behind this theory is thatthe earth was made with a balance of “green house gasses” (AGU, 2003). These gasses are naturally occurring within the atmosphere and they essentially make the planet habitable by keeping it warm.

However, it is the argument that is against human activity being the primary cause of global warming that provides a superior explanation to this currently unknown global phenomena we call global warming. Despite the overbearing support against this argument, there is too much factual evidence about the complexity of the atmosphere and all of its elements that outweigh the predictions being made and then amplified significantly. Using supporting facts leads to a superior argument than using mathematic estimations, which consistently fail to meet their expected results. The changes in climate, including temperature change and rising sea levels, have all been happening for thousands of years providing historical evidence to show this change in climate as a natural occurrence. The most critical aspect of the argument is that rising levels of atmospheric CO2 do not necessarily cause global warming, which contradicts the core thesis of human-caused climate change as stated in a publication made on ProCon.org where the director of Greenpeace International Patrick Moore spoke on the relationship between the CO2 emissions from human activity and global temperature. He states that "there is some correlation, but little evidence, to support a direct causal relationship between CO2 and global temperature through the millennia” (ProCon.org). It is important to acknowledge that regardless what the actual

A scientist that reports for National Geographic Magazine stated, “Since 1990, yearly emissions have gone up by about six billion metric tons of “carbon dioxide equivalent” worldwide, more than a 20 percent increase”(“Causes of Global Warming”) Humans are the cause of global warming. Overpopulation of the human race has resulted in a multitude of carbon dioxide gas getting trapped in the atmosphere, warming the earth as if it was a greenhouse. Carbon dioxide (Co2) is a “waste” gas of human beings. One human approximately exhales two and one third pounds of carbon dioxide gas a day(Palmer) Consequently, the gas is warming the earth from the core up. Humans are the cause of global warming.

One of the leading cause of climate change is the emission of greenhouse gases, such as Carbon Dioxide (CO2), water vapour, methane and nitrous oxide. There is undeniable evidence from hundreds of reputable sources that due to CO2 and other major greenhouse gases the Earth is warming up. The results of this have become extremely noticeable. The average temperature of the Earth has increased by 0.75°C since 1880, carbon dioxide emissions have increased 401.58 parts per million, land ice decreases

During the last century, human activities in agriculture, industry and technology have brought about a change in the chemical composition of the atmosphere. This change so far has not had a noticeable or discernible effect on world climate, but if these same activities continue, global climate change will become irreversible. The major contributing factor is the increase in the amount of carbon dioxide and other gasses in the atmosphere. These gasses are being cited as the cause for a "greenhouse effect" where they trap the heat of the sun and cause global climate change, specifically a warming trend

Carbon dioxide is the greenhouse gas naturally found in the atmosphere. Since the advent of the Industrial Revolution in the 1700s, humans have devised many inventions that burn fossil fuels such as coal, oil, and natural gases, which, along with other human activities such as clearing land for agriculture or urban settlements, help some of these greenhouse gases accumulate in the atmosphere that in turn trap more heat radiation in the atmosphere causing the Earth’s climate to become warmer than it would naturally (Mastrandrea). This unnatural phenomenon is termed global warming by scientists and they blame it for an increase in the Earth’s surface temperature of about 0.6°C (about 1°F) over the last 100 years (Mastrandrea).

What has changed in the last few hundred years is the additional release of carbon dioxide by human activities. Fossil fuels burned to run cars and trucks, heat homes and businesses, and power factories are responsible for about 98% of U.S. carbon dioxide emissions, 24% of methane emissions, and 18% of nitrous oxide emissions. Increased agriculture, deforestation, landfills, industrial production, and mining also contribute a significant share of emissions. In 1997, the United States emitted about one-fifth of total global greenhouse gases.

The concept of global warming has become one of the most widely debated and controversial topics of our time. Scientists learned long ago that the earth’s climate has powerfully shaped the history of humanity. However, it is only in the past few decades that research has revealed that humans have a significant influence on the climate as well. A growing body of scientific evidence indicates that since 1950, the world’s climate has been warming, primarily as a result of emissions from the burning of fossil fuels and the destruction of tropical forests. More importantly, an article titled "Global Warming" published in the New York Times shows that methane, a gas that is emitted from landfills, livestock and oil gas facilities,
