Global Warming is due to the greenhouse effect. The greenhouse effect is a naturally occurring process that aids in
heating the Earth's surface and atmosphere. It results from the fact
that certain atmospheric gases, such as carbon dioxide, water vapor,
and methane, are able to change the energy balance of the planet by
being able to absorb longwave radiation from the Earth's surface.
Without the greenhouse effect, life on this planet would probably not
exist as the average temperature of the Earth would be a chilly -18
degrees Celsius, rather than the present 15 degrees Celsius.
As energy from the sun passes through the atmosphere a number of
things take place. A portion of the energy (26 % globally) is
reflected back to space by clouds and particles. About 19 % of the
energy available is absorbed by clouds, gases (like ozone), and
particles in the atmosphere. Of the remaining 55 % of the solar energy
passing through the Earth's atmosphere, 4 % is reflected from the
surface back to space. On average about 51 % of the sun's radiation
reaches the surface. This energy is then used in number of processes
including: the heating of the ground surface; the melting of ice and
snow and the evaporation of water; and plant photosynthesis.
The heating of the ground by sunlight causes the Earth's surface to
become a radiator of energy in the longwave band (sometimes called
infrared radiation). This emission of energy is generally directed to
space. However, only a small portion of this energy actually makes it
back to space. A few naturally occurring atmospheric gases known as
the greenhouse gases absorb the majority of the outgoing infrared

...ons of ozone gas are found
in two different regions of the Earth's atmosphere. The majority of
the ozone (about 97 %) found in the atmosphere is concentrated in the
stratosphere at an altitude of 15 to 55 kilometers above the Earth's
surface. In recent years, the concentration of the stratospheric ozone
has been decreasing because of the build-up of chlorofluorocarbons in
the atmosphere. Since the late 1970s, scientists have discovered that
total column ozone amounts over Antarctica in the springtime have
decreased by as much as 70 %. Satellite measurements have indicated
that the zone from 65 degrees North to 65 degrees South latitude has
had a 3 % decrease in stratospheric ozone since 1978. Ozone is also
highly concentrated at the Earth's surface. Most of this ozone is
created as a by-product of photochemical smog.
Global warming is commonly caused by the excessive amount of greenhouse gases. Greenhouse gases are the gases which work the same way as greenhouse, absorbing the heat radiation from the Sun and emitting it back to the Earth’s surface. This process is called greenhouse effect. In addition, greenhouse gases include carbon dioxide, nitrous oxide, water vapor, methane and Chlorofluorocarbon or commonly called CFCs.
The greenhouse effect is known as the rising in earth's temperature above from its normal temperature. In the atmosphere, there are certain gases, such as methane, carbon dioxide, nitrous oxides, water vapor, and ozone, which aid in this activity by reflecting the heat back to earth. Because of this process earth can maintain a suitable temperature. Around 57 degrees Fahrenheit, which are considered to be a normal temperature. The average temperature on earth would be zero degrees Fahrenheit, 18 degrees Celsius), if this radiation is not trapped, and as a result of life would not be as we are seeing now. In this way, these greenhouse gases are primary and very important for the survival of the living organisms on earth. What makes the earth,
Many of the scientists believe that earth is getting hotter, and the average temperature of earth is increasing each year due to the excessive burning of fuels on earth. The idea that the earth’s temperature is increasing is called global warming, and humans are the main cause of it. In spite of this theory, many believe that there is no global warming because the surface temperature has not increased steadily, but documents and researches show that global warming is real, and it is endangering lives of the animals on the earth.
Global Warming, much of what does or does not happen forty years from now rests on our actions or inactions taken between now and then. The crucial question is whether we should pour all our resources into mitigation – reducing our carbon emissions. According to scientists who study the climate there are other environmental problems; “we now face a global crises in land use and agriculture that could undermine the health, security, and sustainability of our civilization”.
Human induced climate change resulting from an enhanced greenhouse effect is probably the greatest environmental threat facing the world today. Specifically, the emission of greenhouse gases such as carbon dioxide may be classified as the primary culprit. As a result of greenhouse gases entering the upper levels of the earth's atmosphere, it diminishes or breaks down the earth's Ozone layer. With this loss of this protective blanket, harmful radioactive rays from the sun enter the deeper into the earth's atmosphere. This creates a rise in the overall temperature of our planet, along with alterations in the global environment, ecosystems and way of life for the habitants of earth.
Global warming is onset by the greenhouse effect, which is categorized by the entrapment of greenhouses gasses “The greenhouse effect results when certain gasses trap the energy of the sun as it radiates upward from the earth’s surface. Carbon dioxide in the atmosphere accounts for about two thirds of the greenhouse effect.”
Firstly, global warming is said to be caused by the high levels of carbon dioxide released into the atmosphere by humans. Smoke produced by factories, vehicular exhaust, and the burning of fossil fuels such as coal in power plants are the primary sources of carbon dioxide. The theory is that carbon dioxide being released into the Earth's atmosphere is steadily building up because it cannot escape into space. The theory as to why the carbon dioxide in the atmosphere actually causes the Earth's average temperature to rise is outlined as follows:
This Earth is getting older and older. Can you imagine what life will be like if the temperature in the Earth keeps on rising due to the excessive amount of heat trapped in the atmosphere? No one would want that to happen. The atmosphere plays an important role in our daily life. It keeps the Earth warm, which is also known as the greenhouse effect. Due to ozone depletion and global warming, the atmosphere is not able to function normally like how it used to. Human activities such as the burning of fossil fuels and clearing of forests contributed and intensified the greenhouse effect. These activities also lead changes to the Earth’s climate. We live on this Earth and it is important for us to prevent the Earth from further damage caused by the greenhouse effect. It is our job to protect our beloved Earth. To save this Earth, we should learn what greenhouse effect is, what cause it, what the impact is, and the steps or ways to prevent it.

Global warming has been generally concerned with the whole world. Over the past 100 years, the average temperatures of the Earth experienced 2 fluctuations which are cold-warm and cold-warm. However, the Fifth Assessment Report of Intergovernmental Panel on Climate Change (IPCC) points out that the average global temperature has increased 0.4 - 0.8°C in the overall trend. Even worse, scientists from the IPCC (2014) forecast the temperature will be higher and higher in the future.
The earth’s climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the buildup of greenhouse gases –– primarily carbon dioxide, methane, and nitrous oxide. The heat-trapping property of these gases is undisputed. Although uncertainty exists about exactly how earth’’s climate responds to these gases, global temperatures are rising. Go to the Emissions section for much more on greenhouse gases.
Global warming and the greenhouse effect are issues discussed by scientists all the time. A natural process that keeps earths temperature at a livable rate is called the greenhouse effect. The energy from the sun warms up the earth when the rays from the sun are absorbed by greenhouse gasses. The gasses then become trapped in the atmosphere. Carbon dioxide, water vapor, methane and nitrous oxide are the most common greenhouse gasses. Greenhouse gases cause the radiant heat of the sun to be trapped in the Earths lower atmosphere which causes global warming. If there weren’t any greenhouse gasses, the earth would be really cold due to very little sun rays being absorbed on the earth. Global warming can and will lead to several problems that affect the environment in which we humans live in. These problems can lead to warmer temperatures all around the world, it can endanger animals and the wildlife, and it can lead to widespread flooding from the glaciers melting. Here are a few more future effects that I will discuss in more detail about. Damage to human health, Severe stress on forests, wetlands, and other natural habitats, how fish will be affected. Global warming is a serious problem that will affect our generation when we are older.
Global warming is a huge global issue concerning millions of people across the globe. Global warming is primarily caused by the emission of greenhouse gasses into the atmosphere. These gasses are causing the Earth’s atmosphere to become thinner which, in return, causes an increase in temperature throughout the world. Although, most people believe that climate change is a natural phenomenon, others believe that humans are playing a huge roll in the increase of global warming.
Global Warming is a condition caused by greenhouse gases and human activities. The increased concentration of greenhouse gases due to activities such as deforestation and fossil fuel burning is causing the Earth’s atmosphere and oceans to warm up. As a result of this, global warming has some serious effects in the shape of extreme weather, species extinctions, and rising sea levels. These effects can contribute to the changes that are taking place all over the world, most of which are dangerous enough to pose a threat to the survival of life on Earth in the future.
However, the climate is changing from human activities, which have greatly increased greenhouse gases. We call this change global warming. Global warming is a phenomenon in which the earth’s temperature rises from an increase of carbon dioxide or other greenhouse gases. When we burn fossil fuels as coal, gasoline, diesel and oil, it brings forth carbon dioxide. Because of human activity, greenhouse
