Global warming is caused by an effect called the greenhouse effect. Gases like Nitrous Oxide, Water Vapour, Carbon Dioxide, and Methane are released into the atmosphere by human industries and are forming a blanket around the earth. When sunlight enters the atmosphere it passes through the atmosphere as ultraviolet and visible light. (Ultraviolet meaning of electromagnetic radiation, having a wavelength shorter than that of the violet end of the visible spectrum but longer than that of X-rays - a type of electromagnetic rays which are used for medical purposes). It emits shorter wavelengths because the sun has a lot of energy and heat to give off and hotter energy has shorter wavelengths. Some of this energy is then reflected back towards space as infrared energy. (Infrared energy meaning of electromagnetic radiation, having a wavelength just greater than that of the red end of the visible light spectrum but less than that of microwaves. Infrared radiation has a wavelength from about 800 nm to 1 mm, and is emitted particularly by heated objects.) The earth is cooler and has less energy to give off so the suns energy is cooled down and the wavelength increases because cooler energy has longer wavelengths. Now gases such as nitrogen and oxygen that make up our atmosphere are only two particles, and therefor are tightly bound and don’t absorb much heat. But, greenhouse gases, having three or more particles result in being loosely bound structures that are efficient absorbers of
The 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, the Earth’s temperature has been 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.
Global warming represents a very large threat to our planet. But first off, what is global warming? It is the significant increase in the Earth’s temperature over a short period time as a result of human activity. A congruous mix of organisms, people, and environments are being harmed. Ocean levels have risen, species are becoming extinct, and the natural world is not what it used to be. Regardless of whether this is a large risk is yet indeterminate, whatever the impacts of global warming may be, it is most likely that the outcomes will be enormous, causing illnesses and financial decay. Because of global warming, many are beginning to invest in energy-efficient supplies and do a variety of other acts. For example, carbon dioxide (C02) is an important factor on earth. It is causing a warming impact on the world's surface range. Since water vapor itself is an ozone depleting substance, this causes significant additional warming. Then, the warming causes more water vapor to be vanished. The C02 level is relied upon to develop in the long haul due to keeping consuming of petroleum derivatives. Different gases, for instance, C02, Sulfur, CFCs, and Methane are additionally in charge of a dangerous atmospheric deviation. Industrialization, urbanization, and deforestation likewise are expanding the generation of these gases.
According to Robert Frost once said, “ Some say the world will end in fire, some say in ice. From what I’ve tasted of desire I hold with those who favor fire.” This quotation can link to the concept of global warming. Global warming can be interpreted as an increase in the earth's average atmospheric temperature that induces corresponding changes in climate, and that may be associated with the greenhouse effect. I chose to do my cause and effect essay on global warming because I believe it has a significant impact on humans, not only today but especially in the future.
Global warming refers to an extended increase in the earth's average and average temperatures of the atmosphere and water bodies especially the oceans and seas. The problem of global warming has resulted in various negative ramifications affecting humankind. Human activities have significantly led to the increasing effects of global warming that is experienced in different places worldwide. Global warming was experienced in the 20th century when the earth's average temperature rose by 0.60 Celsius from an average temperature of oceans and the atmosphere (Ritter, 11-21). Global warming distracts the typical living conditions since the temperatures increase to extreme limits and deplete the Ozone layer which is meant to protect human being from the effects of direct rays of the sun. The Ozone layer is very significant and needs to be preserved to avoid the impact of direct sunshine which causes sunburns on human skin. It is clear that global warming has been increasing to a more significant extent since the 18th century due to the actions of human beings themselves. The core reason behind this tremendous increase is the new developments in technology and setting up of industries. Industries emit dangerous gases from burning fossils fuels, gasoline hence producing carbon dioxide which depletes the Ozone layer which is purposely meant to shield the earth from direct sunshine. This paper discusses the various causes of global warming that has been majorly attributed to humans
Over the past 50 years, the average global temperature has been increasing at the fastest rate ever recorded. Experts say that the heating rate is only going to increase, while people who deny this say that there has been a “slow down” or “pause” in the rising global temperatures. Scientists say that unless something changes, the average U.S. temperature could increase by 10 degrees Fahrenheit over the next century. (1) Almost 100% of the global temperature increases have been the result of increased greenhouse gas concentration like water vapor, carbon dioxide, methane and ozone. One of the largest sources of greenhouse gas is the burning of fossil fuels leading to the emission of carbon monoxide. (2) Most scientists have agreed that the main cause of the current global warming is the expansion of the “greenhouse effect”. (3)

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.

Scientists around the world have been researching climate change since the 1970’s. One thing most agree on is that the temperature of Earth is rising at a rapid pace and that global warming has been caused mostly by human activity. Our atmosphere contains gases that act as a blanket, because it traps heat from the sun and prevents it from escaping back into space. The trapping of the sun’s heat by these gases is known as the greenhouse effect, and the gases are called greenhouse gases. The main greenhouse gases that occur in nature are carbon dioxide, methane, and nitrous oxide. Without the greenhouse effect, earth would be too cold to support life.
Has anyone wondered why climate is in flux? Who is the major culprit behind this extreme climate changes? “Swedish physicist Svante Arrhenius was the first scientist to assert that heightened concentrations of carbon dioxide in the atmosphere could lead to global warming in 1896.” As global warming is the greatest environmental challenge today, we should be aware that it is actually “a gradual rise in the average temperature of the Earth's climate system and its related effects.”
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.
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 term accustomed to describe a gradual increase within the average temperature of the Earth 's atmosphere and its oceans. Outstanding warming sceptics have, within the face of such proof, acknowledged that global climate change is going on, which humans are the cause. however, a number of the most recent analysis says if we would like to keep the Earth’s climate among the vary humans have knowledgeable, we should leave nearly all the remaining fossil fuels within the ground. James Hansen, NASA’s prime climatologist and one of the first to warn greenhouse warming had been detected, taken off to outline dangerous human interference with climate. In 2008, his team came to the surprising conclusion that this level of part greenhouse gas (CO2) is already within the zone. Warming must be stopped before it affects our life and all of humanity (Skepticalscience.com, 2016)
[Earth’s temperature is definitely warmer than it was hundreds of years ago, but not for natural reasons]. Gradually the Earth’s surface has become warmer over the last century and most scientists believe that the burning of fossil fuels is responsible for the temperature spike. According to Holli Riebeek, the Education and outreach specialist at NASA Goddard Space Flight Center, Global Warming is happening now, and greenhouse gases are responsible. The burning of fossil fuels causes the release of greenhouse gases, which then become trapped inside our atmosphere and cause Earth’s surface to warm. The greenhouse effect provides a habitable environment for all species on Earth, but [the Earth’s atmosphere now contains more greenhouse gases than ever before1]. The Earth is becoming a more efficient greenhouse, which will eventually cause the Earth to become inhabitable. [The natural causes of the warming of the Earth are too minute to explain how rapid the increase in temperature has been in the past 50 years. Between 1906 and 2005, the Earth’s temperature had risen .3 degrees, but in the last 50 years, the temperature increase rate has almost doubled and is predicted to continually increase] (Riebeek). Contrastingly, despite the knowledge and evidence that greenhouse gases are a large factor of Global Warming, some
Have you been suffering from allergies more lately? If so, it could be because of global warming. Currently, global warming is a major problem that the World is facing and is causing many side effects that people are not aware of such as allergies. Given the increase in global warming activities, it is vital that society works to decrease the level of harmful emissions that are caused by toxic gases and pollutants while increasing the amount of wind and solar energy.
The Planet Earth is broken, and we all had a hand in breaking it, inadvertently though it may have been, by adding an abundance of greenhouse gases to the atmosphere that contribute directly to global warming; and we continue to do so every time we start our car, turn up the heat, turn on the lights or throw away trash. Global warming is a problem, caused in large part by human activity, and as it stands, poses a monumental threat to the planet and all of its occupants; while mega polluters do not have an incentive to stop greenhouse gas production, we can, as individuals work towards the solution, greenhouse gas reduction, by improving our awareness and implementing the day to day measures necessary in achieving this goal. The purpose of this paper is to explore global warming, its causes and effects, in order to better understand what we can do to stop it.
