Main Cause Of Global Warming

People have come with varied causes of global warming. Some natural causes are the release of methane gas from the wetlands and the arctic tundra. It has been proposed that the temperature of the earth is influenced by the activities that man carries out. (Michaels 222) Others have proposed that this is due to the climate change that the earth goes through after a certain amount of time.

Most climate scientists agree with the idea that the main cause of the current global warming trend is human expansion of the "greenhouse effect", warming that results when the atmosphere traps heat radiating from Earth toward space. Over the last century, the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2. To a lesser extent, the clearing of land for agriculture, industry, and other human activities has increased concentrations of greenhouse

Humans are pouring carbon dioxide into the atmosphere at a much faster rate than the rate at which plants and oceans can absorb it. Global warming is the increase in the overall temperature of the Earth 's atmosphere; global warming is a delicate topic because it is happening right now no one can stop it from happening. It is already transforming life on Earth, shifting the seasons, raising the temperature and rising the sea level. Other effects of global warming include stronger storms, extinction of species, rapid disappearance of Artic ice, and the increase of the ozone hole. It became an issue in 1988 when a scientist from NASA found that "Global warming has reached a level such that we can ascribe with a high degree of confidence a cause and effect relationship between the greenhouse effect and observed warming" (Hansen). James E. Hansen testimony was a big thing that everyone start to worry about it and everyone was talking about global warming because the media contribute to it. Global warming is a big thing happening right now but we don’t listen to others and we continue with our life’s without looking around us and without helping to stop the cause of it because as a humans we make errors during life but we learn from the errors and the bad choices. Although some people believe mankind is not responsible for global warming, it is a serious problem worldwide and measures are need to help slow the problem.

Water vapor is the biggest greenhouse gas.

Every year, almost 7 billion tons of carbon dioxide is released into the atmosphere by human activity. That is the equivalent of 107,700,000 jet airplanes being in the air at once! This harrowing figure is the main cause of global warming, and has been increasing for the last 50 years. Global warming is caused by the increase of greenhouse gasses, carbon dioxide and methane primarily, in the earth's upper atmosphere directly caused by human burning of fossil fuels, industrial, farming, and deforestation activities. Global warming is defined as an increase in the average temperature of the earth's atmosphere (especially a sustained increase that causes climatic

Researches reveal that natural events as well as human related activities contribute to changes in average global temperatures. AtKisson affirms that global warming is basically a result of increased emission of greenhouse gases into the atmosphere. This atmospheric carbon dioxide (co2) comes from anthropogenic (caused by humans) sources. The concentration of greenhouse gas carbon dioxide, nitrous gases, and methane in the atmosphere has increased evidently due to human activities since 1800. NASA’s article adds:

Climate change is caused by the interaction of humans on the environment. Atmospheric concentrations of carbon dioxide — the main heat-trapping greenhouse gas produced by human activities. Carbon dioxide is a “greenhouse gas” (GHG) that traps heat in the atmosphere, warming Earth's surface. It is generated by natural sources such as wildfires and volcanic eruptions, and by human activities — primarily burning fossil fuels such as coal, oil and natural gas (Weeks 523). “We cause global warming by increasing the greenhouse effect, and our greenhouse gas emissions just keep accelerating,”

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).

Why are the temperatures are steadily getting hotter? Summers getting longer and winters shorter? Glaciers melting and sea levels rising? The reason is Global Warming. What is Global Warming? Global warming is when the world, the globe’s temperature increases and it starts to get hotter. The reason it starts to increase is because of what is called the greenhouse gases. The green house gases are mainly caused by humans which also means that , the humans are causing global warming. Humans have been releasing gases into the air as they go on with their modern lives. The main gas that goes into the atmosphere is carbon dioxide and that comes from everyone, 28% comes from transportation ,10% from agriculture, 20% from industry, 10% commercial and residential, 32% electricity that's 82% of carbon dioxide that's in the atmosphere. The other 18% comes from Methane 9%, nitrous oxide 6%, Fluorinated gases 3%. The first time they discovered and saw the increase in greenhouse emissions was back in 1800’s when the first industrial revolution was happening the scientist discovered this by studying the ancient ice, they also discovered that the level of the carbon dioxide was 290 parts per million (ppm). By 1960 Charles Keeling measured the level of carbon dioxide and it measured 315 ppm. By 1970 April 22 the world marked the first Earth Day on their calendars to raise awareness and help their environment. It wasn't until 1976 that the scientist discovered that carbon

Global warming is the gradual increase in the overall temperature of the Earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide and other pollutants (Collins). The current climate changes that are occurring all over the world have sparked a growing controversy on whether global warming is true or false. Many of these individuals who play a role in this controversy argue that the current climate changes are simply part of the cycles seen in the earth’s geological history or that it is simply caused by an increase in the brightness of the sun. This point-of-view is understandable as humanity is dependent on the climate for survival. However, many climatologists and scientists have found that the current climate changes are much more worrisome than previous climate changes. They have found that carbon dioxide (CO2) levels have increased over the years because of an increase in the use of coal, oil, and gas and that the Earth’s current pattern of warming is greater and faster than that of prehistoric warming episodes.

Global warming has been a hot button lately in the news. The main reason why global warming has been big issue is because people argue if global warming is real or not. There are good points to both sides of the argument. Even though temperatures have not been recorded since around 1850, some scientist believe there is not enough data to confirm global warming , global warming does exist because rise in average temperatures and the glaciers in antarctica and other mountain ranges are shrinking.

Global Warming is the result of the increasing in overall temperature of the earth’s atmosphere that is generally attributed to the Greenhouse Effect. The Greenhouse Effect is caused by the increase of the levels of carbon dioxide, chlorofluorocarbons and other pollutants (Wollersheim) in the earth’s atmosphere. Global Warming is a fact, not fiction but some people still think is it not affecting our earth’s planet. The fact is if we don’t take care of the problem now life on earth will not exist. This is an important topic that needs to be addressed before there is nothing left for the human race which includes animals and plants or any living things that live on this planet. This is no joke, but in this society, people think nothing is going to happen to our planet, I agree it probably will not in my lifetime but what happens in 100,200 years. Look at what scientist have discovered over the past decades with the globe is heating up on land and the oceans. Scientist have been studying this since the 1880s, (Pappas) we need to be educated on how to save our planet. Most scientists agrees that the main cause is human expansion of the greenhouse effect. There are facts the glaciers are melting, the sea is warming and causing the levels of the water to rise which is causing all wildlife to scramble to find a safe place to go. Take the polar bears, with all the glaciers melting they are dying out because of the perennial ice is melting. All of this

Many climate scientists accept the main source of the existing global warming is human increase of the “greenhouse effect”. The greenhouse effect is a natural course that heats the Earth’s surface. When the energy of the sun reaches the Earth’s atmosphere, some of it is reflected to space and the rest gets absorbed by the land, ocean, greenhouse gas. Now the absorbed energy heats up the surface of the Earth and atmosphere to maintain Earth’s temperature and make the planet habitable, however, in the current atmosphere, the problem is human activity

chart that the article displays that China and the U.S emits the most carbon dioxide into the world.

Many businesses, industrial factories, and vehicles produce massive amounts of natural gases that affect the world in many ways. These gas particles that move rapidly and constantly collide with the atmosphere. This causes the air on Earth to contain higher kinetic energy due to the fact that more gas particles from the natural gases are colliding with the air particles. The higher kinetic energy results in higher temperature and heating of Earth’s surface. The heating of the Earth’s surface causes many of the world problems that we have today. As more and more factories and industries produce gases that pollute the world, they also increase the effects of global warming. Gas particles from these natural gases move rapidly throughout the atmosphere. Since these gases are still near the surface of the Earth, these gas particles collide much more and become more rapid creating more kinetic energy. If there is more kinetic energy in these gas particles, there is an increase in temperature. Around the world there are so many products and resources that require the release of gases. These gases, once released, increase the temperature in the atmosphere to be able to melt the ice at the north and south poles. The gas particles are able to spread out throughout the Earth’s atmosphere to trap the heat which increases the temperature of the Earth’s surface allowing the ice to melt.
