The Importance Of Global Warming

In the last 100 years, the amount of greenhouse gases in the atmosphere has increased, causing the Earth to warm by an average of 0.6 degrees celsius, largely a result of burning fossil fuels for energy, transportation, and land use changes increased for food production. The basic science is straightforward and climate researchers have shown that gases such as carbon dioxide, methane and others can trap heat in the Earth’s atmosphere, causing a phenomenon known as the greenhouse effect. Human activities such as industry, transport, energy generation and deforestation all produce these greenhouse gases. In the last 20 years, concern has grown that global warming is inevitable and now considered most probably caused by man-made increases in

It is largely known that the most significant issue facing the planet today is global warming. There is no doubt it is one of the biggest environmental issues throughout time, though it is widely debated among scientists and environmentalists what the main causes are. Global warming isn’t a new issue, in only 1989 the UK Prime Minister at the time warns that the increasing emissions of carbon dioxide into the atmosphere are going to have a significant impact on the earth in the future (BBC News, 2013). The warming of the earth is caused by greenhouse gases, such as carbon dioxide that trap long-wave radiation in the atmosphere. This warming of the earth surface is referred to as the greenhouse effect. Greenhouse gases are the gases, such as carbon dioxide, methane, and water vapour which accumulate in the atmospheric layers prevent heat being radiated from the earth to escape. Without greenhouse gases the earth would be considerably cooler but with increased human activities, temperatures are rising to an unstable level (Arbogast, 2011).

Climate change is influenced by the greenhouse effect which is the increase of Carbon dioxide, Methane, Ozone and Nitrogen Oxide. On one hand, the presence of these gases in the atmosphere make the earth habitable with respect to regulating the earth’s temperature. However, an increase in the concentration of these gases results in trapping energy in the atmosphere and this in turn increases earth’s temperature. “Global greenhouse gas emissions have grown since pre-industrial times, with an increase of 70% between

Global warming is defined “as an increase in the average temperature of global surface air and oceans since about 1950” (White). The global warming controversy is an ongoing dispute with two main sides; one stating that the direct cause to global warming is through people’s daily activities and the burning of fossil fuels, while other people all around the world refuse to believe that human contributions are the main cause, saying that the earth is going through a natural stage of climatic change, thereby resulting in increasing temperatures in the earth’s atmosphere. Rising temperatures and in increase in greenhouse gases shown through the carbon cycle, demonstrate how the greenhouse effect is incorporated into both views on global warming. Over the past 50 years, experts in this field world-wide have been having an unaccountable amount of disputes over global warming, favoring in either of these positions of human causation or natural climatic change.

When carbon dioxide and other toxic gasses are released into the atmosphere, they become too excessive for all the vegetation to absorb. Such conditions lead to the over-accumulation of gasses that form a layer called a greenhouse. The gasses create a greenhouse effect that prevents any heat from escaping the earth (Taylor,881). This means that most of the heat being released from the earth’s center as well as that being absorbed from the sun is retained within the atmosphere. The trapped heat has over time led to the rise in global temperatures which has subsequently had adverse effects on the ecosystem. In essence, the small changes to a temperature that have occurred on a global scale over time can lead to significant and human threatening changes in the global weather patterns. The contemporary warmth has been exhibited by melting ice lands and glaciers as well as increased floods and famines.

Global warming is one of the biggest threats to our planet. The temperature of our planet is increasing because of all the pollution and human activities that causes the climate temperature to change. The most to concede is the increase of seawater level. The clear majority of the coastal cities will be in danger and a few nations may vanish. The increase in temperature will soon melt the ice in the North and South pole. The worldwide increase in temperature is getting worse. The risk of global warming has raised concerns as it is ceaselessly causing harm to the earth in the form of heat waves. Studies have shown that last year’s average global surface temperature, complied from measurements made by thousands of weather stations, buoys, and ships, was 1.69 degrees Fahrenheit warmer than the 20th century average (NOAA). It is because of us that we are causing this planet to have global warming. Carbon dioxide is what warms our planet, we have increased the amount of the air by nearly half, mostly since the 1960s (NOAA). Global warming is as of now having significant and exorbitant impact and these results will just intensify as the planet's temperature keeps on rising.

Global warming has been a conversation holder for the past decade or so. Years ago people believed that global warming was a myth, and was not going to happen. Now for the third year in a row temperatures are becoming warmer and warmer. Scientists are becoming more alert to the steady pace of earth's temperatures rising. In the article “Earth Sets a Temperature Record for the Third Straight Year” by Justin Gillis, he explains that earth is casually becoming warmer every single year. After reading Gillis’s article I would strongly agree with him, I believe his article gives concrete evidence that earth is warming up, and could potentially cause many problems. Global warming is happening and will eventually cause extinction, rise in sea level, and effects on weather.

97% of scientists believe that humans are to blame for global warming because of the industrial activities have raised two hundred and eighty parts per million to four hundred parts per million in the last hundred and fifty years. The burning of fossil fuels like coal and oil has went up the atmosphere because of carbon dioxide the oil and coal burning it, it combines carbon with oxygen in the air to make carbon dioxide when the carbon dioxide reaches the atmosphere, is rapidly distributed between atmosphere, the upper-ocean and vegetation.

It is said that the Earth’s climate has been changing for the past century (State Government of Victoria, 2014). There is new found, stronger evidence that there have been increases in the average temperature across the globe and that the believed to be main cause of this change is due to human activities (University Corperation for Atmospheric Research, 2013). Greenhouse gases are what are most commonly referred to in conversation on climate change. Although greenhouse gases are generally referred to on the negative side, they are also essential to life (Mapstone, 2011). The greenhouse gases which consist of carbon dioxide, water vapor and methane retain heat in the earth’s atmosphere, gently warming our planet to sustain life, just as a greenhouse would in a cold climate, which is evidently where it receives its name. The sun warms the surface of the earth, which then radiates energy back towards space through the atmosphere. The greenhouse gases then absorb some of the radiation and radiate heat in different directions, including towards earth. This is now adding to the heat the surface of the earth is already receiving from the sun. Without the aid of this greenhouse affect it is said that the surface of the earth

Global Warming is a serious problem affecting everyone. The earth’s temperature increases, the ice melts and therefore the sea level rises. Lately, increases in natural disasters are causing more damage and devastating millions of victims and scientist predict that Global Warming may be the cause. What causes global warming is a build-up in greenhouse gasses, such as carbon dioxide, water vapour, nitrous oxide and methane; which contributes to the ‘greenhouse effect’. This effect is when the sun rays come through the atmosphere, but then the heat is trapped in the atmosphere, by these gasses. However, without these gasses the earth would not be able to sustain life as it would be freezing, because the planet would not be retaining heat, and during the day it would be boiling as there would be no gasses to filter the sun’s rays; but unfortunately over the years humans have created too many of these gasses, gradually increasing the earth’s temperature. (Orcale, 2002)

During the last century, human activities in agriculture, industry and technology have brought about a change in the chemical composition of the atmosphere. This change so far has not had a noticeable or discernible effect on world climate, but if these same activities continue, global climate change will become irreversible. The major contributing factor is the increase in the amount of carbon dioxide and other gasses in the atmosphere. These gasses are being cited as the cause for a "greenhouse effect" where they trap the heat of the sun and cause global climate change, specifically a warming trend

Global Warming is the new epidemic that is facing the United States as well as the entire world. Global Warming is the gradual increase of temperatures around the globe. The gradual rise of the average temperature of the Earth’s atmosphere and also the oceans is believed to be permanently changing the Earth’s climate. There is a debate among an abundance of people that and sometimes in the news, on whether global warming is real or not. However, scientists and climate experts all agree that the planet is warming and that could lead to a world wide crisis.

Global warming, as the name implies, is the literally the warming of the Earth all around the globe. Global warming causes many disasters like drought, glacier melting, hurricanes, and rising water. These problems are happening because of Earth’s temperatures going up and more heat everywhere. Some of these aren’t an obvious concern, but these can impact millions of people everywhere. On top of that Earth’s wildlife is suffering these blows harder than people are and are dying out because of it. Wildlife simply cannot adapt to rapid temperature changes in such a brief period. As National Geographics says in their article, What Is Global Warming? “glaciers are melting, sea levels are rising, cloud forests are dying, and wildlife is scrambling to keep pace.” (National Geographics). What the National Geographics team is trying to say that global warming is causing huge problems that impact the entire world. Another author, Amanda MacMillan, says “All but one of the 16 hottest years in NASA’s 134-year record have occurred since 2000.” (MacMillan). What this article is saying is that global warming is real and it is happening now. Science shows that global warming causes not so-natural disasters, that are bad for the human population, but terrible for the overall population of organisms. Studies also show that global warming impacts the environment in such a way that organisms cannot adapt. In conclusion, global warming is the heating of the Earth, through human impact, that causes problems wildlife can’t adapt to.

Life has existed on Earth for a few billions years and it is the evolution of life that has changed the physical nature of Earth. As life diversified, several mass extinction events occurred. We are currently experiencing the sixth mass extinction. The sixth mass extinction accounts for the loss of biodiversity induced by humans (Anthropocene) (George Jackman 2017). For example, currently anthropogenic greenhouse gases are the highest in history which affects the changes in climate (“Global Climate Change” 2014). Climate refers to “long-term average expectations over the various seasons at a given location” (Sadvana et al. 2014, 25). Today’s rapid climate change is thought to be due to increasing atmospheric CO2 from burning fossil fuels. Tremendous concentration of atmospheric CO2 will lead to an increase in earth's average temperature, change rainfall patterns, melt glaciers and ice caps, and raise sea levels (“Global Climate Change” 2014). Climate is an an environmental factor that many species rely on. Unfortunately, the Earth’s climate has shifted dramatically within the last 10,000 years, with some climate changes being more rapid than others (George Jackman 2017). Climate changes affect nesting, migration patterns, life cycles, and population size of many organisms on Earth. Failure to adapt to the changing climate forces species to move to temperatures that are more conducive to their survival or endure extinction. Simoncini et al. 2014, 243)

Greenhouse effect is the process where heat is trapped by greenhouse gases present in the atmosphere to keep the Earth warm. The planet’s atmosphere contains these radiatively active gases, that radiate energy in all direction. Greenhouse gases are already present in the atmosphere; without them the Earth would be significantly cold enough to freeze the oceans. To understand how important and harmful the greenhouse gases can be for the planet, we need to answer these questions. Do extra greenhouse gases upset the Earth’s natural balance and make it even warmer? Is there any extra insertion of the gases in the atmosphere by humans? If so, how significant are the effects? This essay will discuss in detail, the mechanism that
