Introduction
Most people around the world do not fully understand the meaning of the greenhouse effect, or the affects the greenhouse effect has on the world. In fact, many believe that the greenhouse effect is simply contributes to global warming, and that it has no real value to the earth. But what many are not aware of it that the greenhouse effect is the planet’s natural way of obtaining a specific temperature in which living organisms can survive. Many people are not aware of the consequences that our way of life has on the planet, and soon, with the help of global warming, we will all understand.
Greenhouse gasses There are three main greenhouse gases that play a large role in keeping our planet at a stable temperature; carbon dioxide, methane, and nitrous oxide. Other gases produced are troposheric ozone, CFC-12, HCFC-22, and sulfur hexafluoride. The greenhouse effect used to have no legitimate harm on earth, but, humans have been the reason for the increase in these greenhouse gases, therefore creating what we know today as; global warming. Without these greenhouse gases, the earth would be so incredibly cold that no living entity could survive.
Importance of the Greenhouse Effect Because the greenhouse effect is usually only discussed in the context of global warming, this natural process is neglected to be appreciated for its vital role in the planet. Without having the greenhouse effect, there would be no weather on Earth. All of the greenhouse gases
In the world today, global warming and climate change are one of the main issues with the earth. This issue affects everyone and everything in this world, and even though it seems to be a big problem, most people do not seem to care. The most familiar term is global warming and climate change, but greenhouse gases is one of the main causes and is never mentioned. Greenhouse gases are gases that absorb and emit radiation in the atmosphere, hence makes the earth warmer. The importance of this knowledge of greenhouse gases is so the world will know one of the main causes of global warming and climate change and possibly some
Greenhouse gases keep heat close to the earth’s surface making it liveable for humans and animals. However, global warming is happening largely due to an over-emittance of these gases and fossil fuels (natural oil, gasoline, coal)
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
There are four major gases that cause the greenhouse effect. These chemicals are Chloroflourocarbons (CFC’s), Nitrous Oxide (N2O), Carbon Dioxide (CO2), and Methane (CH4). “CFC’s destroy ozone molecules by the thousands, causing a smaller amount of ozone in the ozone layer. This allows more UV rays hit the Earth’s surface, causing a slight increase of the Earth’s temperature. The more ozone molecules destroyed, the more UV rays enter the Earth’s atmosphere, making the temperature even higher”(What Is The Greenhouse Effect).
Global warming is caused due to the presence of the gasses in the atmosphere, mainly carbon dioxide, methane, chlorofluorocarbons and nitrogen oxide
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
greenhouse gas is carbon dioxide. Carbon dioxide is very well known and is released while doing everyday things like driving a car. Carbon dioxide also is the main impacting greenhouse gas along with methane and nitrous oxide. After burning fossil fuels the greenhouse gasses trap heat in
“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
I believe the world is being faced with a serious issue of global climate change due to the greenhouse effect. The greenhouse effect is a naturally occurring process in the Earth's atmosphere that warms the planet. Without the greenhouse effect, on average, the Earth's surface would be about 60oF colder. The greenhouse effect occurs when visible light from the sun passes through the atmosphere and is absorbed by the Earth's surface. Some of that energy is then sent back to the atmosphere as heat. However, greenhouse gases trap that heat, which would otherwise be released into space, raising the temperature of the atmosphere and the Earth's surface. Increases in the amount of greenhouse gases, due to human activities, intensify the heat
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
When one hears the term “global warming,” the first thing that comes to mind is the greenhouse effect. The greenhouses allow sunlight to enter through the windows and then the sunlight heats the interior by trapping the heat. The same thing occurs within the plants, solar radiation is basically absorbed by the Earth’s surface therefore resulting in the warming of the Earth. There is nothing wrong with the greenhouse effect as long as some radiation can escape back into space. We need the greenhouse effect because without it nothing would even survive on the Earth.
The human population is increasing and so is the amount of food we consume; each year food consumption increases 0.5% per person and less than half of the global grain we produce, is directly consumed by humans, this is because the rest goes to feed farm animals. However, factory farms are using more than they can produce, considering the fact that animals are being fed 6 kg of plant protein and in return are only producing 1 kg of animal protein, this also means other people are getting less food. With the human population increasing farmers must grow crops to meet the rising food demand. However, to increase the number of crops produced we need more farmland, which can lead to deforestation and animal habitats being cut down or burnt. So far 38% of the world is covered by farmland, and the area is still expanding. Each year, 12 million hectares of land is lost to deforestation and it is predicted in 2050 more than 120 million hectares of natural habitat in developing countries will be covered in farmland, to meet the food demand. When deforestation is done to create new agricultural land, the crops that replace the trees also act as a carbon sink, but they are not as effective as forests.
Greenhouses are controlled environments for plants to grow in prime conditions. Greenhouses are designed to trap solar radiation to create a warmer environment for the plants and allow the plants to grow where they normally would not. The Earth has a natural greenhouse effect and is vital in supporting life. Greenhouse gases create a sort of barrier to trap some radiated energy. However, the drastic production of greenhouse gases increases this barrier and creates a warmer temperature for the planet [Nature 476.7358, 2011]. Destabilizing the greenhouse effect of the planet can lead to major consequences which has already occurred such as:
The most significant greenhouse gas is water vapor, which plays an important role in regulating climate. The changes in water vapor from human activities such as irrigation and deforestation can affect temperatures on the Earth’s surface (source). The second, is carbon dioxide, which is one of the main reasons for global warming. An increase in carbon emission causes the planet to warm by intensifying the IR energy influx in greenhouse effect (source). Also, carbon dioxide emission comes from deforestation and burning of fossil fuels. The third, is ozone for where life exists on our planet. It absorbs the higher-energy emitted from the Sun before reaching the Earth’s surface (source). However, the ozone in normally seen as smog can cause health problems for humans,
These Greenhouse gases mainly consist of water vapour. As we know, this isn’t directly caused by humankind in significant amounts. However, any increase in the atmospheric levels of carbon dioxide can cause a substantial increase in the Earth’s temperature. And guess whose fault this is: ours. Human beings have risen the CO2 concentration levels by 30%, which is an extremely
