A Research Question Involving Module 2a

In late years, however, excess emissions of carbon dioxide and other greenhouse gases from human activities processes (mostly burning fossil fuels) have started to warm Earth's climate at a problematic rate. This has caused the global average temperature to raise, and may potentially harm many life form on earth in near future. They are generating major greenhouse gases (GHGs) which enhance greenhouse effect. This raises the global average temperature leading to climate change, and may potentially harm many life form on earth in near

Global Warming has been a big issue that has effects on the environment, people, and the world, and if not stopped now, the results could be catastrophic. The main cause of climate change is likely to be the result of too much carbon dioxide (CO2) in the atmosphere. CO2 creates a blanket which traps heat. Burning fossil fuels for energy, such as coal, oil, and natural gas release CO2 which impacts the atmosphere heavily. Waste management and agricultural practices also produce gases that contribute to climate change, such as methane. There are many contributing factors to climate change.

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

Humans are the main factor in the ongoing climate change. Many daily activities contribute to climate change. These activities include the burning of fossil fuels (“A Blanket Around the Earth”). Co2 is the main heat trapping gas (“How Do We Know That Humans Are the Major Cause of Global Warming?”). Humans produce a lot a CO2 every day. When individuals burn fuel, CO2 is released into the atmosphere. The fuels that are being released are jumbling with earth’s natural greenhouse gasses. For every gallon of gas that is burned, 1300 times that of CO2 is released. Also a gallon gas weighs 6lbs, but the CO2 that is released weights over 19lbs (“How Much Does Human Activity Affect Climate Change?”). CO2 is also emitted from farms, landfills, and power plants, which are all human run facilities (“How Do We Know That Humans Are the Major Cause of Global Warming?”). Human activities can also alter earths’ reflectivity. When we construct roads and farm we alter earth’s reflectivity. This causes sunlight to reflect

To begin, carbon dioxide emissions lead to an increase of global temperature. As the sun’s light and energy enters Earth’s atmosphere,

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.

In global warming, %82 of greenhouse gases is from carbon dioxide human activities. Human activities are changing the carbon cycle by… adding more carbon dioxide into the atmosphere. The main human activity that emits carbon dioxide is the combustion of fossil fuels for energy and transportation. Also some companies have contributed to the help on global warming, by using technology that stops carbon dioxide emissions. The Inconvenient Truth explains that carbon emissions are the main cause of global warming, and this climate crisis.

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).

Carbon dioxide is a greenhouse gas that is found naturally in the Earth’s atmosphere. All the extra carbon dioxide, produced by burning fossil fuels, is making the greenhouse gases around the Earth too effective. In other words less energy escapes back into space. Instead, the trapped energy in our atmosphere heats up the Earth’s climate, causing climate change. There are also other things humans are doing that are increasing the amount of carbon dioxide in the Earth’s atmosphere. Plants and treed absorb carbon dioxide as they use it to make food through photosynthesis. This is another cause of an increase in carbon dioxide because of the amount of deforestation that is taking place. So, instead of carbon dioxide being locked away in plants and trees, it is up in the atmosphere. An example of this is

In addition, human also partake in activities that help destroy the planet. Over the past century global warming trend is also caused by human expansion of the "greenhouse effect"- warming that occurs when the atmosphere traps heat radiating from Earth toward space. Gases in the atmosphere block heat from escaping. This is called the greenhouse effect. However, while greenhouse gases increase, the climate changes and result into effects that is dangerous to human health and ecosystems. The gases that have an influence on the atmosphere are water vapor, carbon dioxide and

Scientists have spent decades figuring out what is causing global warming. They have looked at the natural cycles and events that are known to influence climate. But the amount and pattern of warming that is been measured can 't be explained by these factors alone. The only way to explain the pattern is to include the effect of greenhouse gases (GHGs) emitted by humans. One of the first things scientists learned is that there are several greenhouse gases responsible for warming, and humans emit them in a variety of ways. Most come from the combustion of fossil fuels in cars, factories and electricity production. The gas responsible for the most warming is carbon dioxide, also called CO2. Other contributors include methane released from landfills and agriculture (especially from the digestive systems of grazing animals), nitrous oxide from fertilizers, gases used for refrigeration and industrial processes, and the loss of forests that would otherwise store CO2.

The main cause for global warming can be accounted to the “human expansion of the greenhouse effect” (“A Blanket around the Earth” par. 1). Humans expand the greenhouse effect through many activities and processes: using landfills, burning fossil fuels, industrialization, deforestation, agriculture, and even the use of livestock. While it seems like these activities would not have much to do with the expansion of the greenhouse effect, they emit gases that can stay in the atmosphere for an extended period. There are gases in the atmosphere that prohibit heat from escaping; the ones that do not react to alterations in temperature “are described as ‘forcing’ climate change” (par. 2). Carbon dioxide, methane, and chlorofluorocarbons are gases whose emissions have increased due to human activities.

One main cause of global warming is the “greenhouse effect”. According to NASA, this can be described as warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere, such as nitrous oxide and carbon dioxide, sit in the atmosphere, helping block heat from escaping. Human activities such as biomass burning and the use of commercial and organic fertilizers increase nitrous oxide in the atmosphere. Human activity such as deforestation and burning fossil fuels contribute to adding carbon dioxide into the atmosphere. This directly ties in to the next cause of climate change, rising carbon dioxide levels.

Global Warming is a hot topic and one of the critical environmental issues facing the

This produces the so-called greenhouse effect that prevents a drastic cooling of the Earth during the night. Increasing the amount of CO2 in the atmosphere reinforces this effect and is expected to result in a warming of the Earth's surface. Currently carbon dioxide is responsible for 57% of the global warming trend.
