Effects Of Global Warming On The Environment And The Population

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

Worldwide temperatures are rising, carbon dioxide is at a hazardous level, ocean acidification, atmosphere boundary shifts, and extreme events are just a few of the worldwide climate changes happening near and far. It is a controversial issue whether it is taking place in the present velocity because of nature or man. However, global climate changes happen naturally, but they ought not to happen at this increased rapidity; therefore, human activity is a great cause that global climate change is happening at an expanded rate. The greatest contribution of human action is the combustion of fossil fuels, which is one of the primary reasons why the carbon dioxide levels are nearing high-hazard strata. Thus, the scientific confirmation supports that the rise in carbon dioxide levels is significantly generated by people, not nature, and people are ultimately the largest contributor to the atmospheric changes; thus, human beings should implement changes to their energy sources and modify agricultural production in order to lessen the quantity of carbon dioxide emitted into the aura at the extraordinary rate it currently is passing.

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 climate has been drastically changing over the past decade reflecting a wide range of impacts that affect not only the environment, but humans as well. Over the last 50 years the magnitude of global warming has been increasing mainly due to human activities. Since the industrial revolution in the 1800s economic growth has been driven by the progress of manufacturing processes, these have significantly contributed to global warming. It is in this period of time when the global concentration of greenhouse gas levels in the atmosphere had a significant increment from 280 parts per million (ppm) in the 1800s to the modern levels of 400 ppm in 2016. (CITE acs.org).Greenhouse gases are the most significant drivers of climate change due to their persistent effects over a long period of time that can therefore negatively affect the present and future generations.

One of the leading cause of climate change is the emission of greenhouse gases, such as Carbon Dioxide (CO2), water vapour, methane and nitrous oxide. There is undeniable evidence from hundreds of reputable sources that due to CO2 and other major greenhouse gases the Earth is warming up. The results of this have become extremely noticeable. The average temperature of the Earth has increased by 0.75°C since 1880, carbon dioxide emissions have increased 401.58 parts per million, land ice decreases

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

Climate Change also referred to as Global warming, is the process of long term change in the earth’s climate. The increase of “average” atmospheric temperature is the effect. Global Warming is caused by many natural and even manmade processors that continue to affect our environment. The two main contributors to the climate change is the release of carbon dioxide and methane gases. The cost and benefits of global warming will vary greatly from area to area. Balance can be difficult to access for moderate climate change and there will be more negative consequences due to larger changes in climate, which will make life much more harder. Global warming has become a threat to everything and everyone that live on Earth. The question that remains now is, how can we fix this global epidemic? Can reducing our carbon footprint for example, as in buying more fuel efficient cars, cutting back travel, recycling, reducing energy needs, making homes a little bit greener than before help this problem?

For centuries, production and absorption of carbon dioxide was in balance with the ecosystem however, in the last century, human activity has caused detrimental effects to the earth’s atmosphere due to the consequential changes in earth’s natural feedback mechanism. This problem ultimately originated from the industrial revolution in the 18th century where as a result caused the constant production and burning of fossil fuels which has presently caused the warming of earth’s surface. This is ultimately a result of by the greenhouse effect “…which is caused by the interaction between earth’s atmosphere and incoming radiation from the sun.” Greenhouse gases primarily consist of carbon dioxide however others such as “…water vapour, methane, and nitrous oxide…” are also associated to the greenhouse effect. Scientifically, “solar radiation passes through the atmosphere to the surface of earth, where it is absorbed and then radiated upward as heat” is the result of the high emission of greenhouse gases. The most substantial and common way of emission is through the burning of fossil fuels in cars, factories and electricity production. Therefore, human activities over the past century has ultimately caused the more recent problem of the effects global warming is posing to our ecosystem and planet.

Since the beginning of the industrial revolution in recent centuries, the Earth’s temperature increases steadily due to the high concentration of carbon dioxide. The use of energies for transportation, manufacturing, and electricity generation involve in the burning of fossil fuel. These activities produce carbon dioxide to the atmosphere and warm up the Earth. As stated by World Meteorological Organization, “The use of fossil fuel currently accounts for 80 to 85% of the carbon dioxide being added to the atmosphere” (United Nation Evironment Programme - World Meteorological Organization, 2006). In fact, the amount of man-made carbon emission to the atmosphere continues to grow everyday although people acknowledge the danger of the extreme carbon emission. World Meteorological Organization said that the carbon emission rose significantly from just less than 1 billion tons in 1860 to more than 20 billion tons in 1990 (United Nation Evironment Programme - World Meteorological Organization, 2006). As a result, the Earth’s temperature continues to increase over time. Steffen clearly stated “The global average air temperature has risen by about 0.85°C since the beginning of the 20th century, and continues to rise. The period 2001–2010 was the hottest decade on record” (Steffen, 2013).

Previously, climate change was believed to happen naturally. However, over the years, scientists have started to argue that anthropogenic factors are the main contributor. Scientists have also been more confident and forthright in informing the public that climate change is caused by human activities. The IPCC Fifth Assessment Report mentions that “human influence on the climate system is clear, and recent anthropogenic emissions of greenhouse gases are the highest in history” (2013). In addition, most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic Green House Gas (GHG) concentrations (IPCC AR4 2007). In fact, there are many other anthropogenic impacts that cause climate change.

Greenhouse Gases (GHGS) absorb part of the infrared solar radiation reflected by the Earth and as a result, it remains hot enough to make life on earth possible. However, the human being has altered the natural greenhouse effect, making it one of the most serious threats to sustainable development. In recent years, several human activities have caused the excessive emission of greenhouse gas, mainly carbon dioxide (CO2), which is responsible for nearly 50-60% of the global warming scheduled for the next few years (Maslin). In this way, we have exceeded the capacity of absorption of the Earth, which raises the heat retained in the Earth 's surface and gradually increases the global temperature of the planet (Maslin).

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

The issue of global warming should be on the list of our top priorities. Studies show that the average of global temperatures have risen since the Industrial Revolution began. Since the Industrial Revolution, human emissions has quadrupled the frequency of certain heat extremes and many scientists have warned that a failure to bring greenhouse gases under control could eventually lead to a 62-fold increase in extreme heat blasts (Gillis Justin A17). Most of the increase is due to human activities, especially the burning of fossil fuels and deforestation. These activities contribute to a build-up in carbon dioxide and other gases in Earth’s atmosphere. The Earth’s atmosphere is made of gases like nitrogen, carbon dioxide and oxygen. These gases act as a blanket that covers and gives us warmth, but once these gases such as carbon dioxide absorbs heat, but does not release it back into space in which causes the increase in global temperature. This is called the greenhouse effect because it only traps heat but does not release it.

Global Warming is the result of too many gases, which accumulate in the atmosphere. These chemicals build up and produce what is known as greenhouse gases. This results in temperature changes and various weather patterns. The gases, which rise up into the atmosphere retain a lot of heat, which can cause higher temperatures and more moisture in the air. Many of the pollutants in the atmosphere come from everyday human activities, such as using automobiles, factory fuels, and agricultural waste.

There are some compounds present in our atmosphere, mainly in gaseous form, that plays the most vital role in the existence of life in this planet. Had these gases not been present in our atmosphere, planet earth would have been nothing but an ice ball and virtually the existence of life would have been impossible. These life savior gases are known as greenhouse gases. These gases have the capacity of absorbing infrared radiation and maintaining the earth’s temperature by trapping and holding the heat energy from the absorbed infrared radiation, this phenomenon itself is called greenhouse effect (livesciences.com). The recent human activity, especially the industrialization has resulted in production of too much of these greenhouse gases resulting a higher concentration of gases in the atmosphere causing excessive greenhouse effect. This has resulted in a gradual increase of the average temperature in earth’s surface and is commonly known as global warming, which is one of the biggest problem that is threatening the very existence of each and every life living in the planet earth (nasa.gov). The issue of global warming, if not addressed in timely manner is guaranteed to bring severe consequences and certain changes in existing laws, policies and lifestyle could make huge difference in the reduction of greenhouse that ultimately helps keep earth safe and sustainable for all of us and the many generations to come.
