Global warming has been a major concern and has greatly affected the environment around the world for years. Andrew Revkin stated in a New York Times article entitled “A Closer Look at Climate Panel’s Findings on Global Warming Impacts” that climate change throughout the 21st century will lead to increases in ill-health in many regions, as compared to a baseline without climate change. There have been a number of debates regarding this controversial topic, though most of the scientific community can recognize the existence of global warming. Many often question if this effect on the environment is caused by human activity or natural cycles. About 95 percent of scientific studies prove that global warming is essentially caused by man. Although among scientists there is a consensus, all people do not believe it to be true that society contributes to global warming by enforcing the use of electric cars rather than combustible vehicles that give off greenhouse gases and potentially harm the environment. Global warming describes the abnormal temperature change heating up our environment. Climate change is induced by green house gasses such as methane, carbon dioxide, and nitrous oxide. These gases are good when used in appropriate quantities. Methane is emanated from farm animals during their digestive process and is commonly found in swamp gas and exhaust. Carbon dioxide can be found in aerosol cans, hairspray in both aerosol and non-aerosol cans, furniture polishers and cleaners, etc. Nitrous oxide is in laughing gas used at dentist’s offices to keep patients calm during oral surgeries and is sometimes used in scientific studies. The majority of greenhouse gasses come from fossil fuels. Fossil fuels contribute to about 90 percent of... ... middle of paper ... ...xation on citizens of the United States. Citizens would use that money given to buy their electric car due to the expense compared to the cars used today. It has been demonstrated that although among scientists there is a consensus, all people do not believe it to be true that society contributes to global warming by enforcing the use of electric cars rather than combustible vehicles that give off greenhouse gases and potentially harm the environment. Transportation through electric cars has proven to be a viable substitute to the environmentally damaging combustible vehicles being currently used. Although among scientists there is a consensus, all people do not believe it to be true that society contributes to global warming by enforcing the use of electric cars rather than combustible vehicles that give off greenhouse gases and potentially harm the environment.
Global warming is an issue we are all pretty familiar with. It is the climate change that we, humans, are responsible for. The warming of the earth’s atmosphere is caused by the fossil fuels we burn, clearing of forests, and the carbon dioxide and other harmful gases we release into the air (Cunningham, Cunningham, 2009). There are other harmful toxins we use such as pesticides that are supporting global warming. Some effects of global warming include: increase in weather catastrophes, melting glaciers, rising sea levels, and the impact on species could lead to extinction (Cunningham, Cunningham, 2009). “Many scientists regard anthropogenic global climate change to be the most i...
The entire world contributes to the carbon emissions but there are ways we can use less gases to help decrease the amount we use. One way is carpooling. Carpooling can help decrease the amount of carbon emissions we make by having less cars on the road to make carbon emissions. Carpooling also saves you money. Other ways are using alternative fuel sources. Some alternative fuel sources are biodiesel, ethanol, hydrogen etc. There are also cars that use other things like electricity or less fuel. These can be cheaper than just petroleum and less harmful to the environment. “HEVs [hybrid electric vehicle] typically achieve better fuel economy and have lower fuel costs than similar conventional vehicles. For example, the 2016 Honda Civic Hybrid has an EPA combined city-and-highway fuel economy estimate of 45 miles per gallon, while the estimate for the conventional 2015 Civic (four cylinder, automatic) is 35 miles per gallon” afdc. In this day and age we are getting better at carbon emissions and fuel usage but we have a long way to go to achieve almost no carbon emissions, if that will ever
On a daily basis, millions of cars are driven by millions of Americans to millions of different places. For most of those millions of people, their cars are their lives and that's all that matter. A second thought is rarely given to the fact that conventional gasoline vehicles are depositing millions of harmful chemical gases into the atmosphere. Many people in America are not aware of what automobile emissions are doing to our environment. If every American knew all the facts about gasoline vehicles, perhaps then they would be motivated and willing to contribute whatever is needed to save the environment from the destruction that gasoline vehicles are causing. Zero-emission vehicles are a new development and are one of the most aggressive approaches toward preventing global warming. However, there is still a lot of work to be done in order to eliminate conventional gasoline vehicles and begin widespread use of zero-emission vehicles. If there were a national fund for the further development of these vehicles, the effort to eliminate gasoline vehicles would advance much faster. That is why a proposal for the federal government to raise the gasoline tax by $1 per gallon in order to fund further research and development of zero-emission vehicles sounds entirely plausible. If nothing more, it would be giant step in the effort to conserve our natural environment.
The subject of Global Warming is not going away regardless where you stand on the issue. Despite the almost endless warnings of the dangers of smoking, people are still starting to and continue to smoking even though the literature is abundant of the likely consequences to their health. Likewise, there are those that believe Global Warming is true yet they still continue to consume at the same rate even though they believe the increased temperature will cause harm to the planet. The alarm has been set and now is the time to thoroughly review all the scholarly literature to decide where you stand on this powerful issue.
There is an estimate of 1.3 million cars in the world, in the United States alone the ration from person to cars is 1.3. That 's almost 255 million cars in the roads every single day. Just imagine, “Burning one gallon of gas creates 20 pounds of carbon dioxide, and the average car emits about six tons of carbon dioxide every year”(Global Warming And Your Car).Imagine how many tons of Carbon dioxide are emitted into the air by everyone in the world. The carbon that gets emitted into the air doesn 't just affect the climate it also affects us by polluting the very air that we breath. Air pollution causes around 3.3 million deaths worldwide every year. One of the biggest places with contamination is China, the main reason for that is because of all of the factories that they have and all the carbon dioxide that gets let out.People and their decisions are the main reason for climate change, they only think about the present and never about the
Greenhouse gasses have a big impact on our atmosphere. These gasses include water vapor, methane, ozone, nitrous oxide, and carbon dioxide. Each greenhouse gas molecule has three or more atoms that are loosely held together and that eventually release the heat energy and it is absorbed by another greenhouse molecule. Many people talk about greenhouse gasses as if they are a bad idea, but they are not a bad thing. Without these gasses the earth would be zero degrees on the surface. However, too many greenhouse gasses can cause higher temperatures in the atmosphere, cause oceans to warm beyond what they should be normally and weather that is unpredictable. The same with fossil fuels that produce a variety of emissions that pollute our planet 's air and water. These pollutants threaten the environment and its
Global warming has become on of the most controversial issues in the media today. While most of the Western world countries have generally accepted the premise that man's chemical emissions in the atmosphere can and are affected by the world’s climate patterns, in the United States, the issue has become so politicized with many republicans challenging the science behind the theory. Global warming is a greenhouse effect whereby gases are trapped on the earth’s surface causing it to heat up (Maslin 14). It is based on the worldwide temperature records that have been maintained by human beings through their activities since the 1880,s. In addition, global warming is not only caused by human activities only but also through climate changes in solar radiance. The problem is that, humans continue to contribute to the global warming phenomenon. All citizens should work in reducing human activities that cause global warming and also support the development of nuclear power. Scientists deem that, global warming is mainly caused by human activities which accelerate the natural process by creating greenhouse gases in the atmosphere. Human activities have become a great contribution to the greenhouse effect and this means that climate changes are inevitable. They further argue that, if these activities continue and are not reduced, it will lead to more trapping of energy radiated from the earth and this will likely lead to extreme weather and global warming. Global warming should be at reduced levels or else, it will be catastrophic.
I bet you didn't know that the first cars made were all mostly electric. But as time passed gas powered cars became more popular through the years. There were few if any electric cars available as timed moved on. Everyone believed that gas powered vehicles were more convenient than the electric powered ones. I believe that gas powered vehicles are better because gas powered cars have more function ability. The range that electric vehicles have is poor compared to gas vehicles. Electric vehicles don't function very well when the weather is cold. You'll need to charge your car pretty much every night. You are only going to be able to go 80 mph. If you go up a big hill your range goes down. electric vehicles (rather ev's) do pollute but they don't pollute the same way that gas cars pollute.
By and large, the automobile is the only way most Americans travel. Without getting into the details of problems with public transportation, people simply do not consider other options to personal transportation. This becomes especially significant when one considers that cars are the single largest emitter of the greenhouse gas carbon dioxide into the atmosphere. The U.S. produces nearly 24% of the world’s CO2 emissions, a third of which comes from gasoline combustion in cars 4,5. Many scientists cite rising oil consumption as the leading cause...
In this case study I will be discussing advantages and disadvantages of electric cars. Electric cars are cars that are powered by electricity. Electric vehicles are an important part of cutting emissions and reducing global warming. The battery of an electric car stores electrical energy. The electric motor is coupled to the wheels through gears; it converts 59-60% of electrical energy into the wheels. The battery runs the motor which allows the car to move. Electric cars are necessary as they will save money, because electricity is cheaper than gas. Also electric vehicles will help reduce global warming and pollution. However, some people say that electric cars still have environmental costs. The electricity used to recharge EV batteries has to come from somewhere in the world, and now, most electricity is generated by burning fossil fuels. Although electric vehicles are classified as green cars, purists will not appreciate the toxicity of the batteries.
The seriousness of global warming effects both the environment and the people living in it. The question is how do Americans effect the environment and what can we do to fix it? Americans everyday use automobiles as a form of transportation, and although it may seem harmless, the use of these cars are proving to be detrimental in the end. Author Margaret Kriz (2006) states that, “the vast majority of scientists who study Earth's climate agree that the planet is warming, and they blame the greenhouse gases that accumulate in the a...
Electric cars help lower emissions because they have completely clean motors. As time progresses, emission standards rise and will become harder to meet for automakers. Electric motors will always have zero emissions and auto makers won't have to spend extra money to make their engines cleaner and more fuel efficient. Originally, when the internal combustion engine was invented, pollution wasn't a problem. After hundreds of years and the many combustion engines created, all the exhaust has built up. Today, pollution is one of the largest problems in our environment. Every year the average miles driven rises for everyone. When this rises, the pollution rises as well. Toni Marzotto, in "The Evolution of Public Policy: and the Environment," explains how air pollution will continue to keep on increasing:
Transportation sectors like cars, airplanes, motorcycles, and equipment with engines produce carbon dioxide which affects the atmosphere. The number one contributor of carbon dioxide gas to the atmosphere is fossil fuels. According to the World Watch Institute, humans has increased the amount of carbon released into the atmosphere. The increases rate of carbon dioxide into the atmosphere is around 3.8 yearly (Global Fossil Fuel Consumption Surges). According to an UN report, humans have had an influence on climate change and global warming since the mid- twentieth century. Scientists concluded in the report that the increase of gas emissions is one of the main priority causes of climate change. With that conclusion, they predict the probability of mankind producing climate change is from 95 to 100 percent (UNRIC). Meanwhile nature changes on earth at a steady pace, the heat trapping emissions, also known as greenhouse gases, increasing which causes warming up on the earth as year’s progress. The increase of the greenhouse gases may cause human civilization to experienced hot temperature never
Climate changes occur in our earth's atmosphere due to a buildup of greenhouse gases. Greenhouse gases can occur naturally as well as a result of human activities. The greenhouse gases are carbon dioxide, methane, and nitrous oxide. “Carbon dioxide is released into the atmosphere when solid waste, fossil fuels, and wood are burned.” (2) The gases help to warm the surface of the Earth. Each greenhouse gas absorbs heat differently. If natural gases did not occur, the temperature of the earth would be considerably cooler. “Problems can occur when higher concentrations of greenhouse gases are present in our atmosphere because they have enhanced our earth's heat trapping capability.” (3)
Global warming is one of the most serious issues that the human species face today, yet the majority of the population does not pay attention to it. People are not aware of the dangers and do not care about it much because the main effects will affect the next generation and not themselves. Global warming is happening and it is the reason for changing weather and weather extremes such as earthquakes, floods and wildfires. Global warming is caused by societies lifestyle and these lifestyles destroy the environment and affect the whole world. The use of cars, trains, planes, as well as wasting energy for people’s entertainment has a price; this price is that society is in danger.
