The Effects Of Climate Change On The Earth

Climate change is one of the most crucial issues in the twentieth century. There is much evidence to show fluctuations in weather occurring on the earth. Scientists found that the period of global warming is occurring more frequently than the previous time and rapidly increasing temperature globally. The statistic records on the nineteenth century, calculated that the surface of earth throughout the 100 years ago that had average increase of approximately 0.8C. However, during the period thirteen years ago, the average temperature increase around 0.6C and continually warming with an upward trend in the shortest period. These events cause drastic changes which affect human life such as extreme weather (hotter and colder), food and fresh water shortages and higher levels of the ocean. It is important for people to being concern what happens now. This essay will focus on the main cause of anthropogenic changing climate, in order to evaluate and link the outcome of activity.

Most climate scientists agree with the idea that the main cause of the current global warming trend is human expansion of the "greenhouse effect", warming that results when the atmosphere traps heat radiating from Earth toward space. Over the last century, the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2. To a lesser extent, the clearing of land for agriculture, industry, and other human activities has increased concentrations of greenhouse

Climate change occurs when weather patterns change continuously for an extended period of time. This leads to an increase in the global temperature, also known as global warming. When solar radiation is reflected back to space, a tiny amount of it is captured by a layer of greenhouse gases in the atmosphere. These gases include carbon dioxide, methane, nitrous oxide, and many more. Carbon dioxide is the main contributor to the greenhouse effect. This is due to the heavy burning of fossil fuels, deforestation, and volcanic eruptions.

Straightaway, I knew that the topic that I felt was most interesting to me was geoengineering. I felt it was important enough to research since it could affect everyone on the globe. I wanted to know the reasons behind it, so I began the research process questioning if we know enough about climate change to put geoengineering techniques into play. The research process has not only given me time to learn more about a subject I find so important, but I have gained much more knowledge about climate change in general, and the experience has taught me how to critically look at opposing sides to a topic just as intently as I would my own view.

To begin with, it is important to discuss the common causes of climate change. The most prominent and well-known cause is what is known as the “Greenhouse Effect.” The effect is the result of various gases becoming trapped within the Earth’s atmosphere, which alters the reflection and absorption of sunlight. As the levels of the gases increase in the atmosphere, more sunlight is absorbed, causing warming of the Earth. These “greenhouse gases” include carbon dioxide, methane, nitrous oxide, and “F-gases.”

Is it too late to go back? Can we leave our plan in sustainable place for future generations? Climate change is happening weather we like it or not, what are we going to do? Mahtma Ghandi once said “ you need to be the change you wish to see in the world”. Climate change is causing unbelievably high levels of carbon dioxide , the global economy is estimated to drop by 23 percent by 2100. Our glaciers are melting at an unbelievable pace, Zacharie Isstrom is melting at a pace of 5 billion tons per year.

The amount of Green House Gas (GHG) emissions that are produced and released in the atmosphere from Canada, the United States (U.S), and many other countries, is a big issue for the planet’s health since it causes climate change. Climate change has various damaging effects on the earth. It can cause severe weather such as floods, droughts, etc. Some political parties agree that a carbon pricing policy should be implemented, like the Green party, New Democratic Party (NDP), and the Liberals, while other parties think that it isn’t worth implementing, like the Conservatives. Implementing a carbon policy will take a lot of time, effort, and money, and might unfairly target those who are at a disadvantage, like low income people or those living in remote areas, making them pay more taxes. But to avoid the harmful effects of climate change, Canada needs to implement a carbon pricing policy—a method that has made a significant change in many countries that decided to tax or cap carbon emissions.

Throughout the history of the earth, there has been a continual change in the climate of the earth. According to Nasa, there have been seven cycles of glacial advance and retreat within the last 650,000 years. One of them being the last ice age that abruptly ended about 7,000 years ago which marked the beginning of modern civilization. The changes in climate are normally caused by slight variations in the orbit of the Earth around the Sun which causes there be an increase or decrease in the amount of solar energy the planet absorbs. Today, ninety-seven percent of scientist agree that the current climate-warming that has occurred over the past century is most likely due to the activities of humans. The current climate-warming trend is quite significant because it is proceeding at an unprecedented rate due to the human involvement.

Climate change also known as global warming, is the rise in the Earth's surface temperatures. Even though the rise in the Earth's surface temperature may be slight it can still have a wide range of effects on ecosystems, rising sea levels, severe weather events, and droughts. A staggering amount of scientist believe that climate change is caused mainly due to the human use of fossil fuels. When fossil fuels are used, carbon dioxide is released along with other greenhouse gases into the air. Those gases trap the heat within the atmosphere. Some examples of ways humans use fossil fuels are oil, coal, and natural gas. Humans depend on theses fossil fuels to function everyday life. For example we use these fuels to heat our homes, run our vehicles, and are used in the power industry to produce electricity.

Ice melting at the earths poles, sea levels rising at increasing rates, increased precipitation, and the vast migrations of millions of animals to cooler climates all are impacts of increasing temperatures that are happening right now. Within the next century, sea levels will rise 7 - 23 inches, Storms will become much stronger, floods/droughts will become more common, and many, many other negative environmental changes (Cook). These changes in the environment have been the topic of debate for decades, but has become more and more common over the past few years.

To sustain life on earth, the earth temperature must be maintain at a very delicate figure. But what if the unthinkable happens? What if the earth’s temperature was to increase by a just mere half a degree, maybe a full or even two or three, the effects could be devastating to the environment, to me and to you. Unfortunately we may have the opportunity to see the effects of the earth temperature rising a few degrees in this lifetime. According to scientist, for hundreds of thousands of years, a phenomenon known as the greenhouse effect kept the earth at a comfortable temperature to allow life on earth. This process is necessary to support and maintain life on earth. But just like any good thing, too much of it could be dangerous. Greenhouse gases acts as a blanket that is wrapped around the earth. This traps energy in the atmosphere and the energy is then heated up by the sun’s rays. Because of this, another phenomenon has come to be. It is known as global warming. Global warming is constant rise in the global average temperature near the surface of the earth. Although to some, global warming is nothing more than a myth, a rumor to scare the race into rethinking their selfish acts, but global warming is no myth. I believe that global warming is far from a myth, it is real and it is dangerous. The evidence is all around us. If you look to the stars, you can see that the atmosphere is full of human-produced molecules that is casing the earth to warm. If you look at the same

Climate change is an issue that has the potential to affect the environment, communities and the world economy. Scientists advise climate change will cause increases to the likelihood of extreme weather events. Rising sea levels are at significant risk to coastal areas and communities, while the world’s oceans could become acidic which would destroy and fail to support coral reefs and other marine organisms (Climate Change Australia – Dept. Of The Environment 2014). The main cause of climate change, which is also known as Global Warming, is widely spread. It is mostly caused by the emission of greenhouse gases. Greenhouse gases are released into the atmosphere in many ways; including through the burning of fossil fuels and by deforestation

For over a hundred years, humans have understood the possibility of atmospheric warming due to anthropogenic carbon dioxide emissions. As early as 1896, Swedish chemist Svante Arrhenius predicted that a doubling of atmospheric carbon dioxide would raise average global temperatures by 4.95 degrees C (9.0 degrees Fahrenheit) (Valente, 1995). The greenhouse effect, a natural phenomenon that has allowed the development of life on earth, is thought by many scientists to have been radically altered by humankind’s impact on the composition of the atmosphere. The problem lies in humans’ effects on the dynamic nature of the heat exchange process of the sun, earth, and black space. These alterations threaten to transform the global environment. As one author imagined it, “The year is 2035. In New York, palm trees line the Hudson River … Phoenix is in its third week of temperatures over 130 degrees … Holland is under water. Bangladesh has ceased to exist … in central Europe and in the American Midwest, decades of drought have turned once fertile agricultural lands into parched deserts (Rifkin, 1988).”

The development of society and economy has caused varieties of environmental problems in the past decades. Carbon dioxide (CO2), the most common greenhouse gases has caused a great impact on climate change, and to reduce the emission of CO2 becomes a worldwide agenda. (Christopher R.I, 2013) While, Buildings, taking up third of the total UK greenhouse gas emissions (CCC, 2014http://www.theccc.org.uk/charts-data/ukemissions-by-sector/buildings/), have a great potential to reduce the greenhouse gas emissions and improve the sustainable development in the future. One of the non-neglect issue to reduce the energy use and CO2 emission of building is in the construction phases. The embodied carbon accounting 20-50% of the total

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.
