The Causes And Effects Of Global Warming

The quality of air in the atmosphere has undergone drastic changes over the past decades. The rise of the earth’s temperature due to the effect brought about by the greenhouse effect is Global warming. Greenhouse gases such as carbon dioxide absorb more heat that it radiates from the sun which eventually leads to an increase in the amount of heat in the atmosphere. Climate change occurs due to the human and natural changes which help them either decrease or increase temperature. While global warming leads to flooding and the rise of sea water levels, it is also responsible for extreme drought as well as variations in weather patterns. For instance, the arid American Southwest has experienced a rise of 1.5 degrees Fahrenheit on average over the past century which has led to high competition for the depleting water sources, wildfires, extreme drought and decreased snowpack (Silver 219-233). Therefore, adverse climatic changes have been contributed mainly by global warming leading to poor agricultural yields

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.

Climate change is a natural occurrence that happens every so couple of years. The greenhouse effect increases the level of CO2 being released into the atmosphere,which is what triggers global warming. The collection of released CO2 increase temperature. Global warming melts the ice in colder places like Antarctica. This Increases the amount of water that flows in the oceans and rivers. Earth has a balance, so if there is a process and warming then there is a process of cooling. We call these cooling periods ice ages. Ice ages freezes parts of the oceans in the Antarctic, this decreases water vapor.

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.

Global warming is an increase of Earth’s temperature throughout a period of time. Global warming is a disease that is one of the root causes of Earth’s illness. This invisible change has a lot of drastic effects on mankind, wildlife as well as nature. The reasons to these destructions are humans themselves. There are some very obvious ways to tackle the situation. Many of the extraordinary weather changes since the 1950’s are recorded in the instrumental temperature record which stretches out to the mid-19th Century while having thousands of years according to the Paleoclimate Proxy Records [IPCC Climate]. Temperature across the whole world is predicted to change throughout this century and continuing. The Earth’s ability to tackle the emission of heat-trapping gases, as well as the amount of gases released will predict the magnitude of global climate change [NASA].

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)

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.

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.

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

Fossil fuels, including coal, oil and natural gas, have facilitated global economic development by stimulating the industrial sector. Formed when organic matter gradually concentrates over the span of millions of years, fossil fuels constitute the world 's primary source of energy. Upon extraction, they are processed in refineries to create invaluable raw materials such as fuel oil, gasoline and liquefied petroleum gas which meet 82 percent of U.S. energy demanded by catalyzing the generation of steam, electricity and power transportation systems (US Energy Information Administration). Fossil

The earth is getting warmer, animals and their habitats are declining, human health is at risk and the cause of all this terror is Global Warming. Global warming will cause many parts of the world to change. In the next 50 years climate change could be the cause of more than a million terrestrial species becoming extinct. Sea levels will raise which means more flooding and is not good for the plants. With too much water the plants will die and herbivores will lose their food source as well as their habitats. As a result the food chain will be broken and survival for any creature is slim to none. In conclusion, Global Warming is an important issue, but before we can devise any solutions we must first understand the causes. This paper will focus on the causes of global warming and argue that excessive carbon dioxide emissions is the predominate cause.

Global warming is a naturally occurring phenomenon within our planet that needs to be reduced because it is affecting us in many harmful ways. It is one of the most current and widely discussed factors. It has been impacting us negatively in ways such as biodiversity and climate conditions. Several current trends clearly demonstrate that global warming is directly impacting on rising sea levels, the melting of ice caps and significant worldwide climate changes. Over the years, scientists have conducted experiments to understand the causes and effects of global warming and they have searched for solutions. They have warned others about the dangers of pollution and human activities and have urged others to do something about it. In short, global warming represents a threat to all living things on earth.

science shows that is exactly the case. In a report in 2001, the Intergovernmental Panel on Climate Change stated, "There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities”. Global warming comes as a direct result of the greenhouse effect- the trapping of the sun 's warmth in a planet 's lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet 's surface. Our Earth is able to maintain a sustainable temperature because of the Greenhouse effect. Without it, the planet would be adverse and completely uninhabitable. The greenhouse gases water vapor, carbon dioxide, methane, nitrous oxide, and ozone are natural gases that are present in the atmosphere. They cause little to no harm when they are balanced but overtime humans have overproduced them, causing temperatures to rise and a heap of other problems. The imbalance of greenhouse gases is caused by the burning of fossil fuels, deforestation, decomposing organic matter, the use of fertilizer, and CFC’s. In this essay, I will first discuss the specific causes of Global warming, then I will address the effects, and finally detail how we as a society can help save our environment from further damage.

Global climate change has been a concern for everyone since scientists first discovered that our actions from polluting can have drastic effects on our environment. Many scientists began to note the changes in the atmosphere and temperature, global warming, in the mid 1800’s. Many people believe that the Earth’s climate cycles and changes periodically over time. Many believe that the changes occur as a result of human activity. The big questions is what effect is our activity having on the environment.
