What is Global Warming?
Global Warming is the increase of surface temperature due to effect of green housing effect and burning gasses.
Increase in global warming:
There are many things that cause increase in global warming:
Carbon dioxide (CO2):
Human beings have increased the Human beings have increased the CO2 concentration in the atmosphere by about thirty percent, concentration in the atmosphere by about thirty percent, CO2 spread in atmosphere from human breath, industries , smoke of automobiles and fossil fuel etc… when we burn fossil fuel the co2 gases escaped in to air and outer layer of earth. Outer layer of is the layer that reflect the ultraviolet rays of sun. So the co2 and burning gases causes the increase of global warming

The harmful gases emitted from automobiles( bus, car, bike etc) and factories in the form of smoke may cause the air pollution. There gases that are present in smoke are mixed and make a cloud that cause the acid rain. Acid rain effected land and also cause many diseases and also destroy our buildings.
Depletion of Ozone Layer.
Ozone layer is the layer around the earth surface that protect earth from ultra-violet rays of sun this layer reflect these rays. These rays causing dangerous diseases like skin cancer. Ozone layer depletion is also one of the causes of global warming; entering of harmful gases which helps in heating up the Earth. Volcanic Eruptions.
Volcanic eruptions is also one of the major cause of global warming. These eruptions contain dust particles and gases which stay in the atmosphere for years and block the sunlight from reaching the surface of the Earth making it cool. These dust particles affects the balance of the atmosphere and becomes a contributing factor of global warming
By cutting trees there won’t be enough oxygen available in the atmosphere and there will be high amount of CO2 available which will heat the earth up.
Kenneth Hare reviews the scientific evidence on the greenhouse effect and explained that warming on global and increased greenhouse gases is the main issue that impact climate change. Human activity is the one who causes the greenhouse effect. The natural greenhouse effect is benefit to our world and become probable to making life on earth, but the temperature is very high nowadays that harm human, plant, and animal life. For example, the natural resource such as petrol for vehicles and electricity for our necessary needs will produce more than billions of carbon to the atmosphere every year that cause climate change every day in our earth.
Even though cutting down on GHG sounds like it would work to stop or slow down global warming it would not have a huge impact. The CO2 that fills the air already has become to much for the trees to remove from the atmosphere. This doesn 't mean that we have to give up but instead try even harder to save the animals and Earth. Planting tree would provide more oxygen and those tree would also absorb the CO2 that 's flows through the air. Maybe another solution that would at least help would trying not to use a car as much as possible. Riding a bike once in awhile would
The rising of temperatures is caused by factors called climate forcing or “forcing mechanisms”. This includes processes such as variations in solar radiation, variations in the Earth’s orbit, mountain-building and continental drift, and changes in greenhouse gas concentration. Solar radiation gets trapped by gases, which are created on earth, in the atmosphere. The radiation comes from the sun towards earth and bounces off the earth’s surface. However much of the radiation gets trapped by the gases remaining behind which warms our planet instead of going back into space like previously. This is known as the greenhouse effect. Some of the major contributing gases are; water vapor, carbon dioxide, methane, and our ozone layer. According to sources at Real Climate, 36-85% of the greenhouse effect is due to water vapor (including clouds), followed by carbon dioxide at 9-26%, and last all the minor greenhouse gas absorbers at 7-8%. Humans contribute to the greenhouse effect by deforestation, land use changes, and burning fo...
Most climate scientists agree that the main cause of global climate change is the human expansion of the greenhouse effect. This is the global warming that results when the atmosphere traps heat radiating from Earth toward space (climate.nasa.gov). The main gases that contribute to the greenhouse effect include water vapor, carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons (climate.nasa.gov). Human activities are changing the natural greenhouse effect. The burning of fossil fuels like coal and oil has increased the amount of carbon dioxide in the atmosphere (climate.nasa.gov). Carbon dioxide levels have increased from 280 parts per million to 379 parts per million in the last 150 years due to human act...
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:
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,
A greenhouse gas is any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere. By increasing the heat in the atmosphere, greenhouse gases are responsible for the greenhouse effect, which ultimately leads to global warming. (EPA Environmental Protection Agency, 2014)
Humans have caused global warming by doing many things but the main three are burning of fossil fuels and green house gas emission, deforestation, and excessive use of chemical fertilizers. Global warming is like a bad dream going worse.
Greenhouse gases cause the radiant heat of the sun to be trapped in the Earth's lower atmosphere, which causes global warming. If there weren’t any greenhouse gases, the earth would be really cold due to very little sun rays being absorbed into the earth. Global warming can and will lead to several problems that affect the environment in which we humans live. 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.
Volcanic activity also causes the release of certain elements that may block the sun and also contribute to the increase of greenhouse gases in the atmosphere. The most destructive human contribution to climate change is fossil fuel combustion, which results in the release of carbon dioxide and other greenhouse gases into the atmosphere. Increased carbon dioxide, methane, nitrous oxide and halocarbon 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.
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.
Global warming is an increase in average global temperatures. This will lead to rising temperatures of the oceans and the earth’s surface. Coal is a main contributor to global warming because so much electricity is produced from coal-burning power plants. According to the book Global Warming by Peggy Parks, “In the United States, more than 50 percent of all electrical plants use coal, which also provides power for about 40 percent of the total electricity generated throughout the world” (43). Global warming is also caused because of deforestation and the burning of fossil fuels. Many people say that global warming is natural; however, people speed up the process. Global Warming needs to be taken serious because as the temperature rises, it causes melting of polar ice caps, a rise in sea levels or unnatural patters of precipitation which can result in floods. This can also have an effect on wildlife such as the food chain. Many species have been dying of starvation and many have to move to different places due to the temperature changes. Possible solutions to Global Warming is for people to switch to LED light bulbs as it gives the same light and uses less electricity, wash clothes in cold water, buy less products, and to spread the
Scientists, economists, and policy makers all agree the world is facing a threat from climate warming. Climate warming is caused by excess greenhouse gases such as carbon dioxide, which are heat trapping gases. Human use of fossil fuels is a significant source of these gases. When we drive our cars, heat our homes with oil or natural gas, or use electricity from coal-fired power plants, we contribute to global warming. Including any loss of trees or forests also contributes, considering trees convert carbon dioxide to oxygen.
The common definition of global warming is a gradual increase in the overall temperature of the earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide and other pollutants (Global warming, Wikipedia). Moreover, the effects of global warming will bring ecological and social changes. Because there is no exact way to predict the effects of global warming, it is almost impossible to say how strong global warming will affect life in the future. Scientists blame the greenhouse gas effect in combination with societies greenhouse gas emissions for the rising temperature. The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions. Since part of this re-radiation is emitted back towards the earth’s surface and the lower atmosphere, it results in an elevation of the average surface temperature above what it would be in the absence of the gases (Intergovernmental Panel on Climate Change). Simply, global...
