1. a) Greenhouse effect is the direct natural result of Sun powering climate on the Earth. Sun’s radiation is passing through the Earth’s atmosphere which in turn causing the Earth’s surface to warm up. As an estimation, about 30% of the solar energy is bouncing back to the space as a results of the Earth’s atmosphere. The other 70% of solar energy is attracted by the Earth’s surface and atmosphere. In order to create a balance, Earth has to reflect this extra amount of energy back to space but, part of this reflection is absorbs by Earth’s atmosphere and will be sent back to Earth. This process is warming up the Earth’s surface and prevents the temperature on the Earth’s surface to drop below zero Celsius degrees. This is called natural Greenhouse effect but, due to various human activities such as deforestations and fuel burning and other factors have exacerbate this natural process of Greenhouse effect in which created the global warming [1]. The primary greenhouse gases are water vapor (H2O): from the water on the Earth’s surface. Carbon Dioxide (CO2): its increase in the atmosphere is due to the fuel burning process. Methane (CH4): its increase in the atmosphere is due to several reasons such as melting permafrost, landfills generate CH4, and when ocean temperature rises causes release of Methane. Nitrous Oxide (N2O): agriculture and soil cultivating cause increase in the amount of N2O in the atmosphere. Chlorofluorocarbon (CFC): released to the earth’s atmosphere
When the atmosphere is warmed it emits IR radiation, with a portion of the energy acting to warm the surface and the Earth?s atmosphere. As a result the average surface temperature of the Earth is higher than it would normally be without the atmospheric absorption and re-radiation of IR energy. This is known as the ?Greenhouse effect?. The predictions of the future of these greenhouse gasses being in our atmosphere is based on how much we put into the atmosphere and how much is consumed. One thing is for certain, there are still large controversies on how much of these gasses that are let into the atmosphere are by natural or man made processes. (2-453-454)
The greenhouse effect on earth results from a higher concentration of carbon dioxide, water vapor and methane in the atmosphere.
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 greenhouse effect refers to radiation from the sun as it warms the earth. This is caused by the presence of several greenhouse gases, carbon dioxide being one of them. Carbon dioxide is formed when carbon compounds undergo oxidation reactions. Carbon dioxide helps confine heat in the earth’s atmosphere as it reflects from the sun to the earth, and thus contributes to the
“The Greenhouse Effect” or “Greenhouse gases” have become somewhat of scary concepts in relation to climate change. In fact, without the Greenhouse effect, the average temperature of the Earth would be 5F rather than the current average at 59F. Greenhouse gases are composed mostly of water vapor, but also carbon dioxide, methane, and certain types of clouds. These gases lie in the troposphere of the atmosphere and allows the shortwave radiation of the sun to pass through the atmosphere and warm the Earth’s surface as energy is absorbed, while the longwave radiation is delayed from being transmitted back into space through greenhouse gases. The waves are absorbed by greenhouse gases and bounced back to the Earth’s surface, conserving
The primary cause of climate change is the human expansion of the greenhouse effect. The greenhouse effect is a natural occurrence, which NASA defines as “the warming that results when the atmosphere traps heat radiating from space” (NASA). During the greenhouse effect, heat from the sun passes through the atmosphere, which is made up of various gases. When the heat from the sun reaches the surface, some of it radiates away from Earth, back into space. However, some of the gases in the atmosphere, known as greenhouse gases, absorb this heat, preventing it from escaping (World Meteorological Organization). The greenhouse effect keeps the Earth at a habitable temperature. The World Meteorological Organization, or WMO, states that the greenhouse effect and
Humans are polluting our atmosphere causing the Greenhouse Effect. What’s the Greenhouse Effect? “The Greenhouse Effect can be visualized as follows: imagine that Earth has been encircled by a giant glass sphere. The heat of the sun penetrates through the glass. Some of the heat is absorbed by the Earth, and some is radiated back towards space. The radiated heat reaches the glass sphere and is prevented from dispersing any further”(Global Warming The Facts). This makes the heat bounce back towards the Earth, which heats it up tremendously.
Throughout history the Earth has warmed and cooled time and time again. Climate changes due to subtle shifts in orbit, the atmosphere or surface, changing, or the Sun’ energy varying. Now the force that has the greatest influence on Earth’s climate is humanity. Human activity since the Industrial Revolution has affected the climate because the burning of fossil fuels has an impact on the greenhouse effect. The greenhouse effect is a naturally occurring phenomenon, but due to human activity there are increased levels of greenhouse gases. The increased levels, trap the sun 's energy and it warms the planet’s surface above the normal temperature. It’s the equilibrium of the incoming and outgoing of the sun’s energy that make Earth habitable, but now there is an offset because more is being trapped. The offset is global warming. Global warming is the unusually rapid increase in Earth’s average surface temperature over the past century, primarily due to the greenhouse gases released by people burning fossil fuels. The arctic places are primarily impacted by global warming and place that arose with the most concern is Alaska. Alaska is home to wildlife and human inhabitants. The main concern is that Alaska is melting and will continue to melt in the future. If Alaska continues to be affected by global warming, then there will be a large impact on the state as a whole.
The issue of global warming should be on the list of our top priorities. Studies show that the average of global temperatures have risen since the Industrial Revolution began. Since the Industrial Revolution, human emissions has quadrupled the frequency of certain heat extremes and many scientists have warned that a failure to bring greenhouse gases under control could eventually lead to a 62-fold increase in extreme heat blasts (Gillis Justin A17). Most of the increase is due to human activities, especially the burning of fossil fuels and deforestation. These activities contribute to a build-up in carbon dioxide and other gases in Earth’s atmosphere. The Earth’s atmosphere is made of gases like nitrogen, carbon dioxide and oxygen. These gases act as a blanket that covers and gives us warmth, but once these gases such as carbon dioxide absorbs heat, but does not release it back into space in which causes the increase in global temperature. This is called the greenhouse effect because it only traps heat but does not release it.
It is known that global warming contributes to climate change worldwide. Climate change directly affects the environment, but also affects aspects of one’s everyday life such as technology. Although not apparent, technology can propel or inhibit climate change. As many know, global warming is due to an excess of carbon dioxide in the atmosphere. Recently, an oil and gas company, Exxon Mobil, was accused of not warning the public about the risks of climate change; the extent in which the company contributes to climate change. Many believe this was due to the fact that the company wanted to protect their profits. Essentially, by releasing such information the company would face backlash from environmentalists as well as the possibility of receiving violations from the federal government. Environmental and social justice groups did not cease. They demanded that a federal investigation occur in which such allegations were researched. The groups addressed a letter to Attorney General Loretta Lynch comparing the fraudulent activity of Exxon Mobil to the tobacco industry in the 1950’s. Exxon Mobil denied the allegations declaring that they finance accurate scientific research.
The greenhouse effect is what allows life on Earth and the atmosphere contains trace gases which are designed to retain heat. The gases that are present in the atmosphere are water vapor, carbon dioxide, methane, ozone, and nitrous oxide. These gases act as a global insulator and help control the Earth’s atmosphere. It all begins with sunlight which is a form of energy that is mostly absorbed by land, oceans, and a portion of the sunlight is reflected back to the atmosphere. Once the earth warms up, it then gives off energy in a different form which is called infrared radiation or electromagnetic radiation. The planet need some of the greenhouse gases because without them the
Global warming alludes to the marvel of expanding normal surface temperatures of the Earth in the course of the last one to two centuries (Weart). The idea is identified with the more general marvel of environmental change, which alludes to changes in the totality of characteristics that characterize atmosphere surface temperatures, as well as precipitation examples, winds, sea ebbs and flows, and different measures of the Earth 's atmosphere according to (Brown). A global temperature alteration alludes to a normal increment in the Earth 's temperature, which thusly causes changes in atmosphere designs. A change in the net vitality accessible to the global climate framework is called 'radioactive constraining it can be characteristic or anthropogenic.
Global warming is phenomena linked to temperature rising because of emissions of carbon dioxide and other gases. It is one of the most important debates of today because of the seriousness of its impact on life on earth. The issue though is debated for its being just a reality or as a theory. Scientists are of the view and they provide evidence as well to support their argument that industrialization and energy utilization has the caused emissions of certain gases in our atmosphere. Those emissions are causing the temperature rise globally. So, in one way or the other, humans are cause of this trouble to the planet earth. They say that the rising temperature is melting glaciers and rising water level which would cause floods. On the other
In these days Global warming is one of the major problems of 21st century in front of the world. The major cause them is carbon emission. Every time fossil fuels such as gas, coal or oil burn, it releases carbon dioxide into the atmosphere. The effect of all this extra carbon dioxide in the atmosphere is that the overall temperature of the planet is increasing. Whilst the average global temperature is increasing, on a day-to-day level the climate is changing in unpredictable ways. So it is necessary to control the emission of atmospheric carbon and for that people have suggested different kinds of ideas. Carbon tax is considered as one of the effective ways. Carbon price is the tax on the emission of carbon into the atmosphere than the decided level as well as it is a tax on energy sources which emit carbon dioxide into the atmosphere. It is effectively a tax on pollution (Wright, 2011). However, some people argue that there could be some ways to change the climate like energy conversation and planting trees, these ways could be good but a carbon tax’s environment effects such as reducing the amount of carbon in the atmosphere and decrease the temperature, increases in consumer product prices and inflation as well as an effect on the employment rate, putting a price on carbon is the best solution for climate change because it is the most effective way for climate change.
Earth’s temperatures are largely determined by the balance between the amount of sun energy entering the atmosphere and the amount of energy lost from the earth into space. The natural greenhouse effect is a band of gases that trap heat emanating from the planet’s surface. These gases are water vapour, methane, nitrous oxide, chlorofluorocarbons, tropospheric ozone and mainly carbon dioxide. These gases allow visible sunlight energy to penetrate deep into the atmosphere; they are then absorbed by oceans and land masses. When this stored energy is released back to space as infrared radiation and heat, the greenhouse gases act as an insulating blanket in helping to maintain warm temperatures needed for basic human survival. This is what scientists call the “greenhouse gas effect” Without it; scientists estimated that our planet would be 35 degrees cooler than usual, which would be too cold for an eco-system to sustain. We are contributing to the release of these greenhouse gases by burning waste, wood products, and fossil fuels that emit carbon dioxide into the atmosphere. Our farmers use synthetic fertilizers that emit nitrous oxide and methane is produced in our processes of composing waste in landfills, and last but not least the natural population growth increases our usage of these greenhouse gases when there
