The Causes of Global Warming and Its Effects on the Environment

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)

Greenhouse gasses in the atmosphere form the atmospheric CO2 blanket. This is formed when the sunlight that has passed through the atmosphere is radiated back towards space after it has warmed the earth’s surface. The greenhouse gasses trap this warmpth within earth’s atmosphere, by absorbing the heat energy with greenhouse gas molecules, and this keeps earth at a temeperature that can sustain life. As humans produce more greenhouse gasses, the atmospheric CO2 increases, which means more heat energy is trapped within the atmosphere causing Earth’s heat content to increase. According to the NOAA Earth System Research Laboratory, “CO2 has increased by nearly 43% in the last 150 years”. This increase in heat content causes temperatures to rise,

Global warming over the past 50 years has been experiencing rising global temperatures from the human trend “greenhouse effect”. The role on human activity have produces greenhouse gasses such as carbon dioxide, methane and nitrous oxide causing much of earths temperatures rising over the past 50 years. The impacts of Global warming are fueling frequent droughts, heaver rainfall, hotter heat waves, and powerful hurricanes. Global warming occurs when greenhouse gasses, carbon dioxide, and other hazardous collect in earth’s atmosphere absorbing sunlight and solar radiation trapping heat and causing temperatures to rise. In the United states, the burning of fossil fuels to make electricity is the largest source of pollution, producing carbon dioxide. Fossil fuel burning such as coal and oil power plants are the country’s biggest polluters. The country’s second largest source of carbon pollution is transportation sector. Transportation sectors such as automobiles, planes and trains generates about 1.7 billion tons of carbon dioxide emissions a year. Due to the advancements of scientist, energy efficient technology, modernized power plants now burn less fossil fuels decreasing the emission of carbon dioxide. As a result, the effects of global warming are melting glaciers, effecting agriculture, disruption of habitats, and the spread of conditions favorable to pathogens.

Earth is warming up, so what does this mean for the billions of people that will be affected, if global warming continues? Global warming is the act of Greenhouse Gases; which is Carbon Dioxide, Methane, Nitrous Oxide and Oxygen in the form of water vapor. These greenhouse gases are how the Earth stays warm, heat comes from the sun and with the help of greenhouse gases; the heat from the sun becomes trapped; to keep the Earth warm. Since the industrial revolution, which increased the use of fossil fuel, Earth’s temperature is rising at an alarming rate (Gale Video, 2015). Global warming is affecting the lives of billions of people, with extreme weather, effects on food production, and rising health concerns.

What is global warming? Global warming refers to extreme changes in the Earth’s climate. The term illustrates dramatic increases in atmospheric and water temperatures experienced as a result of growing amounts of greenhouse gas emissions. Humans are responsible for producing these gases via cars, electricity, and factories. The main products of these activities that are to blame for global warming are methane and carbon dioxide; as carbon dioxide, methane, and chlorofluorocarbon compounds go farther and farther into the Earth’s atmosphere, they deplete the ozone layer. Holes in the ozone are allowing harmful ultraviolet rays (that are usually deflected by the ozone layer) to make their way to lower levels of the atmosphere. Greenhouse gases absorb and give off radiation from the UV rays, contributing to extreme temperature conditions. Some of the effects. Global warming has had extreme effects on the planet. Earth’s average surface temperature has been increasing; since the 1880s, temperature has increased by between 1 and 1.5 degrees Fahrenheit. While this may sound like a small number, it has heavily impacted other aspects of our global ecosystem, and it is continuing to rise at a faster rate. Arctic ice is vanishing and glaciers are melting; as a result, polar bears, penguins, and other animals have begun to suffer.

Greenhouse gases produced by human activity such as CFC’s and halons are destroying the planet and are a main factor in global warming. Greenhouse gases are affecting the atmosphere in many different ways. For example, the heat from the sun warms the Earth and is usually radiated back into space but due to the gasses, the heat is stuck in the atmosphere warming the Earth excessively. As the human race expands the need for materials expands with it. The chopping of wood and deforestation is making the greenhouse effect worse. The lack of trees to turn harmful gasses for the atmosphere like Carbon Dioxide are diminishing and making the problem ever more worse. Even though we are trying to combat these powerful gases, the emission into the atmosphere is too much and is continuing to contribute to global warming.

Global warming is now one of the hottest debates in politics. With the recent events taking place, such as the U.S withdrawing from the Paris Agreement. It has created such a fiery showdown in debates from both sides of the political parties to express their thoughts on the issue. By all means, individuals are allowed to have opinions, but such a scientific topic needs to be addressed by facts only. In depth, the information that is presented often into global warming is greenhouse gases and the effects of it. Greenhouse gas are any gaseous compound that is capable of absorbing radiation therefore traps heat into the atmosphere. With this in mind, the effects of greenhouse gases and the result in sea level rise affect the Earth despite the claims that global warming is a natural process.

Global warming occurs when CO2 emissions and other greenhouse gases collect in the atmosphere and absorb the sunlight and the light collected bounces off the earth’s surface. Normally, it would escape into space, but the pollutants get trapped between the ozone and the surface of earth. This causes a greenhouse effect which raises the temperature of the earth. These temperatures can be very harmful to the environment (MacMillan).

Global Warming mostly occurs when carbon dioxide and other air pollutants collect and absorb sunlight and solar radiation that has bounced off the earth’s surface. Normally, this heat would leave the earth and escape into space, but the pollutants trap the heat and cause the planet to get hotter. This is what is know as the greenhouse effect. The largest source of trapped heat in the United States is the burning of fossil fuels to make electricity, this produces about 2 billion tons of CO2 every year. The second largest source of carbon pollution is in the transportation sector, which produces about 1.7 billion tons of CO2 every year. (3)

It has been known that Earth’s atmospheric temperature has risen over the decades, the exact term for this is called “Global Warming”. So, what exactly does this mean? To simply state it, heat is emitted into the atmosphere and then eventually released. Some gases such as carbon dioxide, water vapor and methane capture heat more efficiently than others and are called “greenhouse gasses”, and if the atmosphere contains more of these gases, it retains more heat and becomes warmer, thus causing the rise in atmospheric temperature. “Global levels of greenhouse gases have been steadily increasing. In 1990 they were more than 14 percent higher than in 1960. According to the National Oceanic and Atmospheric Administration (NOAA), which measures long-lived greenhouse gases and publishes an Annual Greenhouse Gas Index (AGGI), greenhouse gases increased 37 percent from 1990 to 2015, and of that, carbon dioxide accounted for 80 percent of the increase (Keating).” This results in significant changes in climate and weather patterns. The rise in average temperatures is crucial and is already causing changes in the climate, “Documented changes include the net loss of ice due to melting glaciers and slowly rising sea levels as the ocean gets warmer and its waters expand (Keating).” So where exactly do these gases in the atmosphere come from, Scientists have discovered that “One significant factor, the rise in greenhouse gases, has been attributed to the activities of humankind. Burning

Global warming is the long term trend in the increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth. This entrapment of greenhouse gases is what is causing average temperatures around the world to rise. Global Warming is responsible for the increase in natural disasters, because since the global climate has been continuously increasing over the years it has increased the chances for natural disasters to occur around the world.

The increasing concentration of greenhouse gases in the atmosphere is the cause of Global Warming. Greenhouses gases are gases that trap heat in the atmosphere to make the earth warmer. Greenhouse gases are: Carbon Dioxide, Methane, Nitrous Oxide, and Fluorinated gases. Each gas’s effect on the climate depends on three main factors:

The warming of Earth’s surface begins with the greenhouse effect, which is the leading cause of global warming. The greenhouse effect is the exchange of incoming and outgoing energy emission that warms the Earth. A great example of this phenomenon given by Marc Lallanila, writer of “What is the Greenhouse Effect?” is when a car parked in a cold, sunny day. The solar radiation that is coming in warms up the inside of the car, but the solar energy that is going out is trapped inside the car’s closed windows. Greenhouse gases are the gases in the atmosphere that absorb radiation, such as water vapor, carbon dioxide, methane, and nitrous oxide. Out of all these greenhouse gases, carbon dioxide is the primary gas produced due to the combustion of fossil fuels from electricity, transportation, and industrial

World facing one of the biggest problem is desertification due to environmental changes human abuse of forest resources as fuel and avail land for residence agriculture cultivation. Wood is considered to be main source of fuel of urban and rural population of India. Use of fossil fuels results in air pollution which is a major problem and directly resulting in smog and degradation of human health and plant growth. The impact of global warming on the environment extensive and affects many areas. Due to warmer temperatures are causing the ice to melt in Arctic and Antarctica will increase sea level and change the composition of surrounding sea water.

Greenhouse gases are compounds in the atmosphere that can trap and hold extra heat, which increases the temperature in the atmosphere. Greenhouse gases is the cause of the greenhouse effect that leads up to global warming. The greenhouse effect is the trapping of the sun’s warmth in the lower atmosphere that is due to the visible radiation from the sun. The solar radiation reaches the Earth’s atmosphere, then the rest of the sun's energy is absorbed by the oceans and lands which result in the heating of the Earth. After that the heat from the Earth goes towards space, some of the heat is trapped in the atmosphere by greenhouses gases which make the Earth warm enough to tolerate living life. The burning of fossil fuels and land clearing start to increase the number of greenhouse gases which travels into the atmosphere. The result of trapping extra heat cause the Earth’s temperature to rise. Scientist's has proven that the constant increase of heat in the atmosphere is caused by humans. The reason humans are proven guilty for the increase of global warming is because of the amount of carbon that is put into the atmosphere. Carbon is released from burning coal, oil, and gas or cutting down and burning forests. Carbon (CO2) is known as the main source of heat-trapping gas which is mainly responsible for the increase of warming over the years. The removal of trees is another cause of global
