Although the greenhouse effect is important, the increase in all of these things create an unexpected rise in temperature for the ecosystem. By doing this, polar ice caps, scientists believe, may melt creating worldwide flooding. Temperatures on earth have increased approximately 1.4°F since the early 20th century. Over this time period, atmospheric levels of greenhouse gases such as carbon dioxide (CO2) and methane (CH4) have notably increased. Both sides in the debate surrounding
For example, the greenhouse effect contributes to global warming causing the polar ice caps to melt, which increases the sea levels and causes floods. Greenhouse gasses also alter the weather, as when the temperature increases, evaporation of water does as well. This leads to an increase in rainfall and dry soil due to evaporation, both of which negatively impact agriculture, due to lack of ideal soil and an excess amount of rain, which negatively affects the yield of vegetation. As the concern about greenhouse gases, or rather carbon dioxide increases, so does the urgency to find a method to reduce the CO2 emissions. Fortunately a method, Geosequestration or Carbon Capture and Storage (CCS), has been discovered and is said to be a promising method for reducing the amount of CO2 being emitted.
Over the years greenhouse gases have exceeded the regular rate, having more nitride oxide and carbon dioxide in the atmosphere heats up the earth more rapidly and does not let heat escape. When doing this this actually hurts the ocean and causes ocean water to evaporate more quickly. By adding more greenhouses gases through power plants, factory’s and cars which we have altered the natural cycle. By doing so the earth is getting warmer. Why we call it the “Greenhouse Effect” In 1824 Joseph Fourier named it the greenhouse effect because it used the same principle.
Does Human Activity Influence Global Climate Change? Global climate change is the gradual increase in the overall temperature of the atmosphere of the Earth. It is caused by carbon dioxide, chlorofluorocarbons, and other pollutants. The biggest contributor to global climate change are greenhouse gases (gases that trap heat in the atmosphere) such as carbon dioxide, methane, and nitrous oxide. An unnaturally large amount of these “greenhouse gases” are released by human activities like burning fossil fuels, deforestation, and mining.
With no greenhouse effect, the average of the global temperature of the Earth would change from 15 to -18 Celsius. In addition, the concentration of the carbon dioxide has increased and that is because of human influences. The releasing of this gas is caused by many activities that humans do, such as burning of fossil fuels and deforestation. As many scientists claim, this phenomenon will lead to enhancing the greenhouse effect and this will lead to making the planet warmer (Masih,
The trapping of the gases which brings about a green house effect makes life on the sustainable, but it also has the potential to destroy life as we know it. About a third of the sun’s energy is usually reflected back to earth through bright surfaces, water and even glaciers. However, two thirds of this energy is absorbed by planet Earth. This results to warming of oceans, lands, and air/atmosphere. Much of this heat is usually radiated back into space, but some is stored in the atmosphere.
Carbon dioxide does not only cause problems in the atmosphere but also in the ocean. The coming of industrial advancement has brought many changes in the earth’s environment (Gibson et al., 2011). Industrialization has brought an increase in gases released into the atmosphere; carbon dioxide forming the largest percentage. The ocean absorbs about 30% of the carbon dioxide in the atmosphere and, thus the increase of carbon dioxide in the atmosphere leads to a corresponding increase in the amounts the ocean absorbs. When the ocean absorbs carbon dioxide it reacts with water to produce chemicals such as bicarbonates and carbonic acid, which lowers the pH of the ocean.
Natural Causes of Climate Change The earth’s climate is influenced and changed through natural causes like volcanic eruptions, ocean current, the earth’s orbital changes and solar variations. Volcanic eruptions - When a volcano erupts it throws out large volumes of sulphur dioxide (SO2), water vapour, dust, and ash into the atmosphere. Large volumes of gases and ash can influence climatic patterns for years by increasing planetary reflectivity causing atmospheric cooling. Tiny particles called aerosols are produced by volcanoes. Because they reflect solar energy back into space they have a cooling effect on the world.
Human Impact on Cycles Patrece Scales Professor Michael Gehosky October 26, 2012 There are many ways humans have impact on carbon, phosphorus, and nitrogen cycles. The carbon cycle is involved in movement of carbon between atmosphere, biosphere, oceans, and geosphere. Natural gas, oil, and coal are known as fossil fuels. They are commonly burned to generate electricity where ever it is needed. When a human use oil in his/her car, van, or truck, they have a great bid of impact on carbon, because when oil is being burned carbon is released into the atmosphere at a very fast rate, than it is removed.
Atmospheric Pollution and Global Warming Environmental Science / SCI 275 3/6/2011 Instructor Name Atmospheric Pollution and Global Warming For nearly half a century, hundreds of scientist from around the world have been studying global warming and its effects. Global Warming is a direct result of atmospheric pollution generated by both natural and man-made sources. The air pollution given off by natural and man-made sources create trace gases that float up into the air and get trapped in the earth's atmosphere. Essentially, global warming is the product of accelerating the greenhouse effect. The greenhouse effect occurs naturally and is caused by the cycle of gasses that rise from the earth's surface and fall from the earth's atmosphere (the carbon cycle is one example).
