Essay on Global Warming

NGS integrates greenhouse into other major policy initiatives, such as the Natural Heritage Trust, and launches new measures to increase greenhouse emission reduction activities across the Australian community. It provides the strategic framework for an effective greenhouse response and for meeting current and future international commitments. It will provide a fresh impetus for action by governments, stakeholder groups and the broader community and set directions for that action into the next century.

Global Warming is an increase in the average temperature around the world. Scientists have been able to trace the global climate and concluded that over the last ten thousand years, the climate of the earth has been relatively constant. In the twentieth century, the global temperature increased 0.740°C. The change in the warming, and cooling, of average global temperatures cause climate change, a change related to climate patterns such as temperatures, rainfall, wind and humidity. This flux in temperature is affected by multiple factors making it hard to determine the true source of problem. Evidence supports that the earth's warming is natural; however, some data indicates that the warming trend has increased due to human activity.

87% of all human produced carbon dioxide emissions come from the burning of fossil fuels like coal, oil, and natural gas. Out of this 87% coal is 43% of that and oil is 36%, and lastly natural gas is 20%. The burning of fossil fuels releases energy which is turned into heat, therefore being released into the atmosphere polluting it. In approximately one year 33.2 billion tons and carbon dioxide emissions were

     Carbon Dioxide plays a key role in the atmosphere. This gas has properties that allow it to sustain and hold in heat, which in turn warms the planet (EIA, 2004). Carbon, the primary component of carbon dioxide; is also the essential molecule for life and is the most basic building block found in all organic compounds. Human activities been blamed for the disruption of the earth’s natural carbon cycles and according to some studies, carbon is being added to the atmosphere faster than the natural processes that sequestrate it. The massive carbon sinks that naturally regulated and fixated excess carbon dioxide have been destroyed as humans have deforested ancient forests for the

• Carbon dioxide (CO2) is a greenhouse gas that warms the atmosphere. • Since pre-industrial times, atmospheric CO2 concentrations have increased from about 280 parts per million (ppm) to over 380 ppm. Current concentrations of CO2 and other greenhouse gases are unprecedented in at least the last 650,000 years, based on records from gas bubbles trapped in polar ice. • Independent measurements demonstrate that the increased CO2 in the atmosphere comes

Scientists and environmental studies students have been documenting a rise in the melting of glaciers. It noticeable that the snow have been melting a lot earlier than expected every year. The production of greenhouse gases was in balance a long time ago, but that balance has been broken due to the human activity at the beginning of the Industrial Revolution. The elevated burning of fossil fuels caused by human activity is the main reason for this balance to break. Plants and oceans cannot handle the huge amount of greenhouse gases that humans have been dumping in the atmosphere. According to The Union of Concerned Scientists, a major group of over two thousand scientists, there has been an increase of more than 30% percent in the concentration of carbon dioxide in the atmosphere, and it is estimated that it will triple by 2100. Carbon dioxide is the most abundant gas liberated in the burning of fossil fuels and also one of the most dangerous gases contibuting to climate change. Carbon dioxide represents about 84 percent of all greenhouse gases emitted by human activities. Carbon dioxide has a property that traps heat, thereby increasing global warming.

These gases “trap some of the reradiated heat, as they act as a partial blanket” for the planet (1). This process keeps the planet much warmer than it would be otherwise, allowing it to be habitable for humans. Since the dawn of the Industrial Revolution in the early nineteenth century, humans have been emitting “billions of tons of extra greenhouse gases into the atmosphere, causing more and more heat to be trapped” (2). The primary greenhouse gas emitted by humans is CO2, mostly by coal-fired power plants. Carbon continues to accumulate in the atmosphere, with emissions today being “six times higher than they were in 1950” (2). This chain of events has caused the Earth to warm by 1.5° F (0.8° C). About 1° F of this warming has occurred since 1970, suggesting that the planet’s temperature will continue to increase more rapidly. This science is at the basis of climate change, and understanding this process is crucial in finding solutions.

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.

A major and controversial topic in the world today is global warming and climate change. Carbon which is one of the bigger contributors to the greenhouse effect, can influence climate change. In its abundance, most of it is stored in the ground within the soil. It is known that respiration, which is the breakdown of molecules into carbon, water, and energy, plays a very large part in the cycling of carbon on the Earth. Understanding how different aspects of our environment can affect the cycling of carbon within soil, we can then apply it to potential changes of climate change and predict what could happen and can set up some pre-emptive measures.

Imagine you are placed into the future. The year is 2100. You begin to live in this

The main reason why I chose to research this topic and why it fascinates me, is mainly based on the fact that our society has convinced us that animal agriculture, which fuels meat consumption, is not responsible for most of our greenhouse gases. When in fact, numerous studies has proven that livestock, and the byproducts that come along with it are responsible for approximately 51% of all worldwide GHG emissions3. Along with that, I find it interesting that livestock is blameworthy “for 65% of all human-related emissions of nitrous oxide– a greenhouse gas with 296 times the global warming potential of carbon dioxide.”3 I found all of the information very interesting, but I had to see the application and actual data.

Global temperatures on the Earth’s surface have increased by 1.1 degrees Fahrenheit during the last century, faster than any time in the last 1000 years (Rauber 41). Consequently, the 1990s was the warmest decade in the last 1000 years (“Global Warming”). As humans emit fossil fuels, greenhouse gasses slowly warm the Earth’s atmosphere (“EPA Global”). This gradual process is known as global warming. As glaciers begin to melt, sea levels rise and coastal areas in Florida may suffer immense losses (“Beach Erosion”). Florida’s tourist economy may also suffer a tremendous loss, as well as agriculture (“Florida Scientists”). With a warmer atmosphere, disease will spread quicker and human health will be threatened throughout the state (“Global

Global Warming, also known as the Greenhouse effect, is a problem everyone will soon have to face. The people of the younger generations should be educated about what Global Warming is and that it is caused due to the way people are treating the environment.

First discovered at the turn of the century by the Swedish scientist Arrhenius, global warming was initially thought to only cause increased greenhouse gases from coal combustion emissions. It wasn’t until fifty years later that the real causes and effects of global warming would be discovered. A British scientist by the name of Calendar correlated the 10% increase of atmospheric Carbon Dioxide between 1850 and 1940 with the observed warming of northern Europe and North America, which began in the 1880's. As for the cause of global warming, scientists generally believe that both the combustion of fossil fuels and other human activities are the primary reason for the increased concentration of carbon dioxide. Human

Nuclear war, bioengineered pandemic, evil self-aware artificial intelligence…climate change? When one tries to imagine the biggest threats to humanity, global warming might not be the first thing that comes to mind. While it may not flashy enough to be featured in apocalyptic movies or comic books, climate change is like our planet’s quiet, slow cancer that, left unaddressed, will almost surely wreak environmental disaster and threaten the global population. To address concerns of global warming, the United Nations convened in 2015 to draft the Paris Agreement, the most ambitious international treaty combating climate change to date. As of October 2017, 195 nations are party to the agreement, leaving only the United States and Syria as
