Recommended: The role of human beings in climate change
You have probably heard a climate change denier say something like climate change is fake and climate change is not human's fault or the worst one out of all of them is, global warming is a hoax. The one thing all of these statements have in common is they are saying humans have nothing to do with global warming which actually wrong, humans may not be the only cause of climate change but we are one of the man ones, which is scary to think about us destroying our own planet. Now I will explain a few of the main ways humans are affecting climate change. The main way humans affect climate change is green house gases, which have been proven to increase the climates and make the earth warmer because basically greenhouse gases trap and don't …show more content…
Another main reason for climate change is people are uneducated about it. The reason that are uneducated about global warming cause global warming and climate change issues is because they think throwing trash in the wrong bin or dropping a receipt on the floor is ok but they don’t know what they are doing is wrong and if they do hopefully they will try to save the world not throw it to waste. Also many people may argue that it’s not the person's fault if they don’t know what climate change is or they don’t know how to fix it. Which I don’t really understand because a lot of big news over the last few years has been about climate change and it doesn’t end there because most schools and workplaces are starting initiatives to help in global warming, so no one can make a excuse saying they don’t know about it or don’t know how to reduce or slow it down. If somehow a workplace or school aren't doing initiatives to stop global warming that shouldn't be an excuse to do nothing about it either because if you hear about it on the news you should be a concerned citizen and research your own ways to help the issue and not just sit there and not …show more content…
Which is creating greenhouse gases, I will focus on the activities humans do that create green house gases and overall affect climate change. There are three main ways how humans create gases, they are, the burning and use of fossil fuels, agriculture some gasses animals exhale and the last main way is the improper disposal of garbage and the excess of garbage being created. The first of those three issues i’m going to cover is the burning of fossil fuels or the use of fossil fuels. Fossil fuels are formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years. Then people extract these fossil fuels from the ground and use and sell them as energy source for us to use. The issue comes into play is when you burn or use fossil fuels the smoke and chemicals are released from it which are greenhouse gases. The greenhouse gases will then essentially keep the heat in the atmosphere not allowing it to escape, which heats the earth up which I will explain why that is bad in another sub topic. Now the big question is what do we use fossil fuels for, well like I stated earlier fossil fuels are a energy source that come in many different forms such as crude oil, coal, natural gas, or heavy oils. An example of fossil fuels
Climate Change is costing the world millions of dollars and is the biggest issue facing society today. Climate change is causing greenhouse gases to build up, ice caps to melt, etc. Some people believe climate change is not a big issue. For instance in the article “Gospel of The Climate Change Deniers” it is stated, “Barton a guy who called Al Gore ‘totally wrong’ about global warming and advised people to get shade to adapt to rising temperatures” (Kroll). Although, this is an appealing mindset, it is illogical because climate change has many more effects than just warmer temperatures. For example, Frank Ackerman: an economist known for his work in environmental economics and Dr. Elizabeth A. Stanton an environmental economist and
First, during the last few decades the Earth is experiencing greater rate of rising temperatures due to greenhouse gases that are being produced by human activities rather than because of environmental reasons, such as solar or volcanic activities. In 2006 the President of the National Academy of Sciences stated: “There is no doubt that the Earth is warming,” also he added that people are at least partly responsible for these changes in addition to regular factors (Cicerone, par.4). Natural factors have produced climate fluctuations on Earth for several million years. People have effected an atmosphere of the Earth just for nearly one hundred years, since Industrial Revolution has begun (Revkin 340). Of course, it is unfair to say that global warming is caused entirely by humans. For example, people can not have an impact on the position of Earth in relation to the sun, or on the galactic density, or such nature events as air emissions of volcanic gases. As a result of these environmental factors, Earth usually had higher rates of temperature fluctuations during the previous million years than it has in later centuries. On the other hand, people are responsible for the highest concentration of greenhouse gases during the last 650,000 years in the atmosphere due to industrial manufacturing, driven by the increase in consumer consumption (Lindsey, par.
First of all, there are more potent gases being emitted into the atmosphere such as the well known greenhouse gas, methane. Methane is mostly associated with cows. Yes, I said it, cows. When cows fart, they release the greenhouse gas methane. Also, methane heats up the atmosphere more than carbon dioxide. So the point here is that global warming isn't mainly caused by humans.
It's no surprise to most people that the idea of global warming is a highly controversial and debated topic. But is there any real evidence that global warming is a growing problem or is global warming just a big scare tactic being used to get people to comply with strict government regulations? Global warming is widely believed to be the main cause of rising average global temperatures. In reality, global warming isn't really all what it has been exaggerated to be. Many of the predicted effects of global warming over time have actually been proven to be false all together.
They believe that humans have caused most of the past century’s warming by releasing greenhouse gases; their levels are higher now than in the last six hundred fifty thousand years. Greenhouse gases happen when sunlight shines onto the Earth's surface, where it is absorbed and then radiated back into the atmosphere as heat. In the atmosphere, “greenhouse” gases trap some of this heat, and the rest escapes into space. Carbon dioxide is the primary greenhouse gas that is contributing to recent climate change. CO2 is absorbed and emitted naturally as part of the carbon cycle, through plant and animal respiration, volcanic eruptions, and ocean-atmosphere exchange. Human activities, such as the burning of fossil fuels and changes in land use, release large amounts of CO2, causing concentrations in the atmosphere to rise. The rapid rise in greenhouse gases is presenting two major problems: extreme weather and melting of ice sheets. In addition, our sea levels could potentially rise too high, possibly flooding
Humans have caused global warming by doing many things but the main three are burning of fossil fuels and green house gas emission, deforestation, and excessive use of chemical fertilizers. Global warming is like a bad dream going worse.
The emission of carbon dioxide has contributed to 80% to the heating of the earth atmosphere. Carbon dioxide is produced due the burning of fossil fuels such as natural gas, coal and oil. The burning of fossil fuel is very important in our society today, because it is used for cooking, used to produce electricity, for heating, for cooling and also for transportation. The industrialization has led to the use of fossil fuel for running machines and driving cars. The building of fossil fuel contributes towards 80-90% of the carbon dioxide we find in our atmosphere today. When the ecosystems are altered and vegetation is either burned or took out, the carbon stored in them is relinquished to the atmosphere as carbon dioxide (What causes global climate change, 2005). Methane is another gas being produced in the process which all have served to increase the greenhouse effect in our atmosphere. Methane is produced from the cultivation of rice, from the burning of coal and from cattle, it has increased by 145% due to human
Fossil fuels are an important part of life. When you turn on the lights, watch TV, or take a shower, the electricity that you are using is being generated by fossil fuels. The three types of fossil fuels are coal, crude oil, and natural gas. They all take millions of years to form, so they are considered to be “non-renewable”- eventually, the fossil fuels will all be used up. One dangerous biological effect of using fossil fuels is ocean acidification. Extracting and transporting fossil fuels can also be very dangerous. Environmentally damaging accidents such as groundwater contamination, land subsidence, and oil spills occur frequently. Global warming is another possible environmental effect. Fossil fuels have a crucial role in modern society, but since they are non-renewable and dangerous, we should reduce our dependence on them and explore alternative energy sources. Wind energy, hydroelectricity, and solar energy are some examples of renewable fuel sources. There are also many things that people can do everyday to save energy (and, in turn, conserve fossil fuels).
Imagine a world under 2 feet of water and in total chaos. Then throw in almost biblical floods, Fissures in the earth that can be seen from space, and Tornadoes that could uplift even the biggest buildings. This is what Al Gore wants you to think. These statements are completely and utterly false. These accusations upon the people of the U.S. are not true and must be silenced.
In talking about global warming, we need to learn what causes the greenhouse effect. Rays from the sun are taken up and absorbed by water vapor that is natural in the atmosphere. The United States emits the largest man made greenhouse gases in the world. As Americans we must realize the responsibility to reduce the emissions. (Gore, Albert) Water Vapor is eighty percent of greenhouse warming. The last twenty percent results from other gases that are in very little amounts. A huge absorber of the sun’s heat rays is carbon dioxide. Us as humans release a lot of carbon dioxide. When fossil fuels are burned, they release big amounts of carbon dioxide. Carbon dioxide is on the increase in our atmosphere due to car emissions. Approximately eighty percent of CO2 increases because of man’s use of fossil fuels. When there is more carbon dioxide in our atmosphere the more sun rays are absorbed. In result to this happening this will cause the earth and the earths atmosphere to warm. When the earth is warming, water temperatures will start to get warmer. Oceans and lakes will get warmer in result f...
Humans and animals breathe out Carbon Dioxide, often referred to as the greenhouse gas, as a waste product. Plants take in this CO2 and use it to make food. This is called photosynthesis. During this process oxygen is released which is then breathed in by humans and animals. This procedure is repeated over and over and a natural balance is obtained. However this natural balance is disrupted by human activity. People of the world are putting more than 5.5 billion tons of CO2 into the atmosphere every year. 75% of this is caused from the burning of fossil fuels. These fuels are burnt all the time to run factories, power plants and vehicles. The main sources of CO2 emissions are electric utilities, residential buildings, industry and transportation. The other 25% is induced by the destruction of the world's forests. The reason for this is that there are less trees and plants to take in the CO2 but there is just as many, if not more, humans and animals to breathe it out.
It is not uncommon for there to be a dispute between experts while regarding a certain topic. In terms of global warming, which is an extraordinarily controversial topic, it would be entirely possible for there to be disagreement. They may be looking at the issue from different viewpoints and they could be basing it off of previous experience. This topic applies to the natural and human sciences because global warming is the gradual increase of the temperature of the earth’s atmosphere as a result of the greenhouse effect caused by pollution and other contaminations via humans. The collection of scientists who believe that global warming is real have their own reasons to defend their claim whereas the others have their own reasons to disregard
There are many different views on whether global warming is actually real or not and possible catastrophic damage it causes. It is a big issue in politics now, everyone is arguing whether or not it is actually real or that it is just a weather pattern. People need to wake up and realize that it is real, just look at the shorter winters and the warmer weather. The Glaciers are melting, crazy weather patterns are happening, so what else could it be? We have more things to worry about as a government though.
Fossil fuels are energy that is in the form of coal, oil, or natural gas that comes from organisms from millions of years ago. The cycle to create fossil fuels takes millions of years to form and is therefore considered a nonrenewable resource of energy. Fossil fuels have been the primary source of energy for man ever since the age of machines, but one of “the main problem[s] with fossil fuels is that there is a limited amount of them” (Problem with Fossil Fuel). As countries become more developed, like the United States, they too will become more thirsty and dependent for fossil fuels. “In 2004, America spent approximately $270 billion to fufill its oil need.” and “90% of all transportation is fueled by oil” (Nakaya 10). With the global rate of fossil fuels going up it is inevitable that they are going to run out, forcing countries to choose an alternative energy source. The other huge problem with dependence on fossil fuels is the effect that the emissions have on the climate. Fossil fuels are made of carbon chains and in order for the reaction...
Scientists, economists, and policy makers all agree the world is facing a threat from climate warming. Climate warming is caused by excess greenhouse gases such as carbon dioxide, which are heat trapping gases. Human use of fossil fuels is a significant source of these gases. When we drive our cars, heat our homes with oil or natural gas, or use electricity from coal-fired power plants, we contribute to global warming. Including any loss of trees or forests also contributes, considering trees convert carbon dioxide to oxygen.
