Global Warming and Greenhouse Gases
The concentration of the atmosphere's main greenhouse gases specifically, carbon
dioxide, methane, nitrous oxide, and water vapor, have increased significantly during the
industrial age. These high concentrations are predicted to continue in the atmosphere for thousands of years to come. This increase in specially carbon dioxide, increases the
infrared energy taken in by the atmosphere, and warming the earth's surface. The Global
mean temperature over the past 150 years has risen between 0.3 degrees C and 0.6
degrees C. Climate changes that have been predicted are based on the continual rise in
Green House Gases. These changes include changes in: increase in mean surface air
temperature, increase in global mean rates of precipitation and evaporation, rising sea
level, and changes in the biosphere.
There are many causes to the rise in Green House Gases in the atmosphere. The
rise in carbon dioxide in the atmosphere is largely related to the combustion of fossil fuels and cement production (Hansen). The increase in methane is do to rice cultivation, animal husbandry, biomass burning, and landfills (Kattenberg). Nitrous oxide is on the rise because of industrial sources like adipic acid and nitric acid production (Kattenberg). Other gases not mentioned above that have a small impact on the Green House Gas
proposed problem, is CFC-11 and CFC-12, these Gases are know to the public as being a
big source of warming, although catalyzing decomposition of stratospheric ozone, they
do not pose a great threat. Since the public was notified of these compounds in
refrigerants, spray propellants, and foam blowing; the atmospheric concentrations have
decreased greatly (Prather).

One of the main causes of the increase in Earth’s temperature is greenhouse gases. Greenhouse gases are gases that are trapped in the atmosphere. The gases consist of carbon dioxide, nitrous oxide, and methane. They trapped heat from the sun from returning back into the atmosphere. Over the last 100 hundred years we have increased the earth’s average temperature by 1.4 degree fahrenheit (Carey). This is mainly due to the fact we are producing ten times more greenhouse gas than before. It is exp...
In the statistical distribution of weather condition and its perfect pattern in an amount of time ranging from decades to centuries to millions of years, a substantial, long-lasting and drastic change is largely known as Climate change. It may be a change in more or fewer extreme weather events or in the distribution of weather more or less the average conditions or in average weather conditions. With the usage of theoretical models and observations methods, scientists, experts and specialists in this particular field actively works in order to perfectly understand past and future climate under certain situation and circumstances.
Greenhouse gases have both advantage and disadvantage. Greenhouse gases are the several group types of gases that can be absorbing solar radiation in the atmosphere such as carbon dioxide, methane, and water vapor. Approximately 75% of the radiations that come from the sun were absorbed by greenhouse gases in the atmosphere. Moreover, about 50% of radiation that was absorbed by greenhouse gas was radiated downward to Earth surface. So because of this phenomenon sustained the overall Earth’s temperature limited it into the proper amount that all of the living thing can be lived. However, greenhouse gases could be the big deal if there are becoming too much. Since the Industrial revolution happen the human activities, fossil fuel comb...
Greenhouse gasses have a big impact on our atmosphere. These gasses include water vapor, methane, ozone, nitrous oxide, and carbon dioxide. Each greenhouse gas molecule has three or more atoms that are loosely held together and that eventually release the heat energy and it is absorbed by another greenhouse molecule. Many people talk about greenhouse gasses as if they are a bad idea, but they are not a bad thing. Without these gasses the earth would be zero degrees on the surface. However, too many greenhouse gasses can cause higher temperatures in the atmosphere, cause oceans to warm beyond what they should be normally and weather that is unpredictable. The same with fossil fuels that produce a variety of emissions that pollute our planet 's air and water. These pollutants threaten the environment and its
Climate change has had many impacts all over the world and evidence of it is very apparent. One example that climate change has impacted the earth is the rising sea levels. Since planet earth is slowly getting warmer by greenhouse gasses, the glaciers and ice sheets around the world are melting, which is adding more water to the oceans. Within the last century, the global water levels have risen by nearly 7 inches. In a quote from “A Student 's Guide” they say,
Greenhouse gas is a type of gas in atmosphere which absorb and emit radiation.Certain gases will block by atmosphere when escaping from the Earth and keeping the Earth warm.Therefore,this process is called Greenhouse Effect .The primary gases in the Earth are water vapour , carbon dioxide , methane , nitrous oxide and chlorofluorocarbons etc.However,human activities are changing the natural greenhouse.According to the IPCC Fourth Assessment Report issued on 2 February 2007 , it can be observed that there was a significant increase in globally averaged temperatures since the mid-20th century .One of the reason is the industrial revolution ,the develop...

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...
Our world is always changing, so is our climate. Some changes are apparent, others not so much. Climate change is an important issue of concern in the twenty-first century. Environment, if it changes at all, evolves so slowly that the difference cannot be seen in a human lifetime (Wearth, 2014). Mostly all scientists predicted that it would take thousands of years for the planet to warm up due to emissions of carbon dioxide from fossil fuels called greenhouse gases. But in the past 200 years, things began to change. The rate and the amount of warming that is happening on this planet are unprecedented. Wearth says, “People did not grasp the prodigious fact that both population and industrialization were exploding in a pattern of exponential
The most destructive human contribution to climate change is fossil fuels combustion, which results in the release of carbon dioxide and other greenhouse gases into the atmosphere. Increased carbon dioxide, methane, nitrous oxide and halocarbons levels in the atmosphere cause an imbalance in the earth’s energy. This is because the gases alter solar radiation and thermal radiation which regulate the earth’s energy. Research indicates that anthropogenic climate change is the cause of the increased global warming over the last fifty years. 57 % of the carbon dioxide emitted is absorbed into the atmosphere while the rest is absorbed into the oceans. Carbon dioxide in the atmosphere is the most central greenhouse gas that is associated with global warming (Eby, Zickfield, Montenegro, Archer, Meissner, & Weaver,
Air pollution and greenhouse gases are the reason for the planet as it is today; the reason why we see campaigns flooding the media informing us to ‘switch off’, ‘save the planet’ and ‘turn down the heat’ and the reason why the government is trying to develop a successful scheme, such as the carbon tax scheme, to reduce air pollution caused by major industries. Air pollution and greenhouse gases are the two immediate causes of global warming and climate change. Air pollution occurs when chemicals or particulate matter enter the atmosphere. They can cause damage to living organisms on the planet, as well as destruction to the natural and synthetic environment (Energy Environment.net 2008). Greenhouse gases are gases in the atmosphere that absorb infrared radiation emitted from the earth. They trap infrared radiation in the form of heat, and hence contribute to global warming. Anthropogenic greenhouse gases are a direct result of air pollution. They are the physical gases emitted that cause air pollution. Naturally occurring greenhouse gases also have an influence on the earth’s atmosphere, though it is not as conspicuous as anthropogenic causes. Together, air pollution and greenhouse gases are intensifying climate change and global warming on a world-wide basis.
As matter of fact, the increasing of greenhouse gases (GHGs) including water vapor (H2O), carbon dioxide (C...
There’s multiple kinds of gases people use that goes into the air each and every day. One
During the last century, burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide. 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
Human activities add to the levels of these gasses, causing more problems. “Automobiles, heat from homes and businesses, and factories are responsible for about 80% of today's carbon dioxide emissions, 25% of methane emissions, and 20% of the nitrous oxide emissions.” (3) The increase in agriculture, deforestation, landfills, industrial production, and mining contribute a significant share of emissions also. These gases that are released into the atmosphere are tracked by emission inventories. An emission inventory counts the amount of air pollutants discharged into the atmosphere. These inventories are important in studying the affects of global warming on the Earth.
