The Causes Of Global Warming

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)

Global Warming is a high rise in the usual climate heat on the Earth's surface. People often use the term climate change to refer mainly to the warming observed since the middle 1800's. Scientists guess that Earth's normal surface temperature rose by about 0.76 Celsius degrees or 1.4 Fahrenheit degrees from the middle 1800's to the 2000's. Researchers have also found that most of the temperature rise happened from the middle 1900's to the 2000's. Normal processes have caused Earth's weather to change in the distant past. But scientists have found big evidence that people activities have caused most of the warming since the middle 1900's.

An increase in Greenhouse gases is the main cause of climate change. Greenhouse gases are gases like methane, CO2, or water vapor, that absorbs the heat from the sun, and

Global warming is caused by several things. One of these is the release of carbon dioxide into the greenhouse gases in the atmosphere by using energy generated from burning fossil fuels.

Global warming, the phenomenon of increasing average air temperatures near the surface of Earth over the past one to two centuries. Climate scientists have since the mid-20th century gathered detailed observations of various weather phenomena (such as temperatures, precipitation, and storms) and of related influences on climate (such as ocean currents and the atmosphere’s chemical composition). These data indicate that Earth’s climate has changed over almost every conceivable timescale since the beginning of geologic time and that the influence of human activities since at least the beginning of the Industrial Revolution has been deeply woven into the very fabric of climate change. Global warming is happening right now and the balance of the

Researches reveal that natural events as well as human related activities contribute to changes in average global temperatures. AtKisson affirms that global warming is basically a result of increased emission of greenhouse gases into the atmosphere. This atmospheric carbon dioxide (co2) comes from anthropogenic (caused by humans) sources. The concentration of greenhouse gas carbon dioxide, nitrous gases, and methane in the atmosphere has increased evidently due to human activities since 1800. NASA’s article adds:

One main cause of global warming is the “greenhouse effect”. According to NASA, this can be described as warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere, such as nitrous oxide and carbon dioxide, sit in the atmosphere, helping block heat from escaping. Human activities such as biomass burning and the use of commercial and organic fertilizers increase nitrous oxide in the atmosphere. Human activity such as deforestation and burning fossil fuels contribute to adding carbon dioxide into the atmosphere. This directly ties in to the next cause of climate change, rising carbon dioxide levels.

There are many reasons to believe that global climate change has been taking place. NASA gives information about the carbon dioxide in the atmosphere which is a cause of many of the effects of global warming. CO2 levels in the atmosphere has drastically increased since the Industrial Revolution as well as methane, nitrous oxide - referred to as ¨greenhouse gases.¨ These gases, especially carbon dioxide, are emitted into our atmosphere at such large levels due to human activities such as factories, and automobiles. ¨There is no question that increased levels of greenhouse gases must cause the Earth to warm in response (NASA).¨ In response to rising CO2 levels and temperature, large ice sheets, ice caps, and glaciers are melting. For example, Greenland and Antarctica - the two largest ice covered land masses - have both decreased in mass. Greenland, losing 36-60 cubic miles of ice per year between 2002 and 2006, and Antarctica losing 36 cubic miles of ice

Global warming is a growing problem and if it is left alone it will destroy the Earth. The main cause of global warming is the industrialization of the world; this began with the Industrial Revolution in the seventeenth century. The Industrial Revolution was the beginning of an era with machines, which lead to mass production, and more jobs. It allowed countries to produce higher quality products in less time. This was the switch from rural, agriculture towns to larger, urbanized cities. The Industrial Revolution then led to a higher

One of the possible causes of global warming are the greenhouse gases. Greenhouse gas emission is one of

Carbon dioxide is not the only gas that contributes to global warming. Other gases include water vapor, methane, nitrous oxide and

A predominant factor as to why global warming happens is more gas particles exposed in the air because of an increase in gases produced by industries. Gases such as CO2 and SO2 are constantly harming our environment by regularly adding more harmful gasses into our atmosphere. Due to forest fires, industries, factories, and new found technology such as the car, many harmful gas molecules are surrounding us. These harmful gas molecules collide with our healthy atmospheric particles which make the amount of gas particles increase dreadfully. Since more collisions between these different particles are occurring, the average kinetic energy is raised therefore the temperature increases as well. As more particles are added into the atmosphere, it becomes denser and gasses are getting trapped into our

The main cause of global warming is due to greenhouse gases as well as other air pollutants that collect in the atmosphere. Sunlight and solar radiation that should have bounced off the earth’s surface is absorbed by these pollutants. If the pollutants weren’t in the atmosphere, radiation would escape into space. Pollutants are known to last as long as centuries within the atmosphere, they trap heat and in turn cause the planet to overheat. This is the greenhouse effect; the greenhouse effect is the cause of global warming.

Global warming is a phrase that has been used in recent history that describes Earth’s surface temperature being warmed. Throughout history, there has been three global warming’s. They occurred in 1850; from about 1860-1880, 1915-1945, and 1975-1978 (see graph). The current warming was thought to have been generated by the discharge by man of carbon dioxide. All three of these periods of warming were divided into a period of universal cooling. The warming/cooling cycles, and their conjoined change in rain patterns are called climate change. Climate change has been happening for the past 11,000 years since the last ice age. Research has recently shown that this abrupt curve is probably a product of what is known as the “heat island effect” rather than be just called global warming. Overall, at its simplest, “climate change”- is simply known as global warming and “climate disruption.” Reason it is called a climatic disruption is because a phenomenon occurs that cause’s weather arrangement and temperatures too change to quickly and unknowingly on a universal scale. Global Warming is an occurrence of increasing average air temperatures close to the Earth’s exterior for over the past two centuries. Since the 20th century, weather scientists have assembled studies of different weather occurrences such as; temperatures, rain, and different kinds of storms. Also studies on the Earth’s ocean currents and the atmosphere’s overall chemical arrangement. This

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
