In recent years the research of scientists has come to public attention and it is a widely accepted fact that the Earth is warming up. What has caused this change in the Earth is still up for debate and a controversial issue. One side is that humans are causing the warming by burning fossil fuels. Staying on that topic, fossil fuels are limited in quantity, and some scientists speculate that we may run out sooner than we are ready for. This is where sustainable energy systems come into play. When using sustainable energy systems such as hydro electric, wind, or cruder methods such as waste incineration, burning of fossil fuels will decrease. With this decrease, or at least slowdown, of fossil fuels we will be able to reduce or maintain green house gas emissions as not to influence the warming of the globe more than we already do. And obviously we will be able to conserve our fossil fuels so that we do not run out while we are still dependent on them. One of the big factors discussed when talking about green house gas emissions is the automobile, however a less looked at factor is electricity generation. Car manufacturers are stuck in their ways, and slow to change how they do business. On the other hand, electrical companies seem to be much more flexible when it comes to making changes and expanding to use resources other than fossil fuels. In many cases, power companies are able to easily integrate renewable or sustainable sources into their power grids, power sources that do not take more from the earth than they give. If power companies were able to use more sustainable sources, it would benefit themselves, the consumers, and the environment. The price of sustainable power does not fluctuate like the price of coal or natural ... ... middle of paper ... ...ergy, and a cleaner planet. Works Cited Erdogdu, Erkan.

Over the past years, planet Earth has been warming up. According to NASA's Goddard Institute for Space Studies, average temperatures have risen around1.4 degrees Fahrenheit/0.8 degrees Celsius since 1880. In fact, the rate of warming is increasing. It was reported by a number of climate studies that the last two decades were the hottest in 400 years. Global warming is a major threat to the planet. It is agreed that humans have caused most of the past century's warming by releasing greenhouse gasses, as we power our electronic lives. The “greenhouse effect” is performed when the gasses let out into Earth’s atmosphere trap heat from the sun. Through the burning of fossil fuels, humans are enhancing the greenhouse effect and increasing the temperatures of the planet. Although the greenhouse effect is what keeps the planet warm, thereby supporting life, too much would also result in severe issues. Now, with the increasing rate of greenhouse gases emissions, frozen glaciers are melting, sea levels are rising, and wildlife is scrambling to keep up with the fast pace. Above that, weather can also become more and more extreme. Something has to be done.
...lobal warming and innumerable animal fatalities worldwide. Workers in the fossil fuel industries undergo irrational risks of an inevitable explosion every day. Thousands of human lives have been taken in offshore oil rig explosions, coal mines and natural gas pipelines. In addition, fossil fuels are directly linked to rising global warming temperatures and drast changes in the environment. Likewise millions of avian fatalities were linked to fossil fuels plants, emitting greenhouse gases are responsible for acidic oceans that harm marine species, and thousands of animals are harmed by oil spills in the sea. Based on this research, fossil fuels are harming the Earth excessively. Renewable energy sources offer efficient and cleaner energy that will benefit the globe. Renewable energy is the definite solution to end human’s heavy dependence upon ancient fossil fuels.
...dition, fossil fuels not only unleash carbon dioxide into the atmosphere, but also is harmful to human when exposed for a long period of time, new energy resources would be needed to replace it such as, wind turbans, biomass energy, wind energy, solar energy, geothermal energy, and hydroelectric energy (Alternative Energy).
...y things that harm our planet every day, however the pollution from green house gasses that our atmosphere endures on a daily bases is by far the worst and will be the end of us if we don’t stop burning these fuels and reverse the effects immediately. With the use of many different alternative energy forms, we could most definitely achieve this. Through the use of wind turbines, water turbines and e85 to replace gasoline, we can take a huge step to saving our planet. This is why the government should endorse alternative energy and set regulations in order to promote the use of alternative energy.
In order to reverse the effects of global warming, we must stop using fossil fuels such as coal, oil and natural gas immediately and switch to alternative fuels such as solar and wind.
Global warming has become a major issue discussed over Medias and governments all over the world today. It is a problem that threatens the whole world because of the destructive impacts it can have on us humans and to the environment. Global warming is not a new phenomenon. It is often referred to as the gradual rise of the earths near surface temperature as a result of increased emissions of greenhouse gases from human activities. The green house gases are carbon dioxide, methane, nitrogen, ozone and water vapor, they act as a blanket that traps enough heat from the sun to warm the earth. This is the green house effect as it is essential to life, for without it the earth would be so cold and would be uninhabitable. If not enough are in the air then the earth would become cold, but if too many gases are released into the air, then we have the problem of things heating up. The releasing of green house gases by humans slowly warm the earth, potentially changing the world?s climate pattern causing sea levels to rise and more disastrous effects. Now that the causes and effects of global warming are known, there can be strategies done to minimize its causes and effects. To achieve this countries and individuals have to work together to fight global warming, agreements made at the Kyoto Protocol is to minimize burning of fossil fuels in world leading countries of greenhouse gas emission including the United States and China.
There will be major changes that have to take effect to reduce the emissions and promoting a clean air economy. We can start to do to more energy efficient things in our everyday lives. Human beings have picked up a lot of habits that waste energy, like leaving a room without turning off the lights. Many Americans go to bed with the television on wasting energy that contributing to climate change. Leaving your phone charger plug into the wall when not; is another example of ways we waste energy.
Due to the use of fossil fuels an increasingly large output of greenhouse gases into the atmosphere, the earth is slowly but surely getting warmer. The problem with this is that ice is melting, making the sea level rise, and something called “Global Weirding” is taking place, changing global weather patterns and creating storms in places where they are otherwise unheard of, and ecosystem are changing, driving some species to go extinct. Since the beginning of the Industrial Revolution, the global economic system has relied mostly on coal and other limited and polluting resources as their primary source of energy. While it may be said that without the use of such resources we would not be at the technological standing we are today, they have
The world is extremely hanging on fossil fuels such as liquid fuels, coal and natural gas. Figure.1 shows that the world will continue to be dependent on fossil fuels in the future. The inordinate consumption of fossil fuels is draining the reserves. Accordingly, the fossil fuels are becoming more pricey. Even so, the most important concern about the enormous use of fossil fuels is not their prices; it is their negative environmental outcomes. With the combustion of fossil fuels, huge amounts of 〖CO〗_2 are released into the atmosphere. These emissions are considered as the main reason for global warming. The global warming consequences have already become visible to be seen as such the melting of glaciers in the poles and sea level uprise.
Climate change is something very real in today’s society. People need to be more aware of what is happening to the world around them. CO2 levels are rising, the ice caps are melting and sea levels are rising. The awareness about global warming should rise...not our CO2 levels. According to the graph shown on NASA’s climate change website, our CO2 levels on earth have rose ever since the Industrial Revolution. Multiple greenhouse gases block heat from leaving Earth’s atmosphere. Over the years, the amount of fossil fuels that are burned, have increased greatly. Burning fossil fuels creates these greenhouse gases. The more fossil fuels we burn, the more greenhouse gases that are stuck in our atmosphere. These gases heat up the earth over time as no heat is capable of escaping.
According to The Fourth Assessment Report of the Intergovernmental Panel on Climate Change, “Temperature records from as far back as 1850 show that the globe has on average warmed by 0.8 degrees celsius, and further analysis has shown that since the 1970s each decade has been warmer.” (IPPC, 2007). It is expected to keep getting warmer according to IPPC and they also are estimating that the average temperature will be 2.5-4.7 degrees celsius higher in 2100. It has also been found that climate change is due to the greenhouse effect which is also produced from human activity. Greenhouse gases in the atmosphere have increased so rapidly since the Industrial Revolution that they are now changing our climate very quickly. High levels are collecting heat that is being reflected from the land and ocean and is making the air and water temperatures warmer because it is preventing it from escaping the Earth’s atmosphere. In order to keep this from happening human activities such as fossil fuel, deforestation and the conversion of land for agricultural use needs to be used
Global warming is an extremely important and troubling aspect of the world’s current situation. This is due to the fact that the majority of the world’s energy production is from non-renewable energy sources, which are energy sources that either can not be naturally replenished or require thousands of years to be restored. Based on our current energy usage growth rates, there are an estimated 100 years left before our natural resource reserves are exhausted. (Non Renewable Natural Resources: How Much Is Left, Environmental Thinker) China alone consumes nearly as much coal as the combined usage of coal from the rest of the world. (US Energy Information Administration, China Consumes Nearly as Much Coal as the Rest of the World Combined) There is visible evidence of this happening with the increasing pollution levels. Carbon Dioxide and Methane pollution levels in the world reached a record high in 2012 and are 260% higher than the pre-industrial levels. (UN: CO2 Pollution Levels at a Record High, John Heilprin) Converting our world into a more renewable energy dependent society is the most advantageous and likely method for preserving our dwindling fossil fuel supply while also protecting the world that we call home.
Global heating and cooling has occurred on a cycle for millennia, however in the past thirty years the increased use of energy and fuels by humans has drastically changed this natural occurrence (Juerg, 2007). The largest cause of this warming is the release of carbon dioxide from the burning of fossil fuels. Carbon dioxide levels are twenty-five percent higher than they were in 1957 (UCS, 2013). This seemingly insignificant change has caused a myriad of negative effects. The endangerment of species, rising of sea levels, and increased natural disasters are just a few examples of change brought about by global warming (Juerg, 2007). Even though global climate change presents a massive problem there are many proposed solutions to fix or delay it. These theories range from creating a giant sun shield in space to the simple practice of “reduce, reuse, and recycle” (Gray, 2009). However the most effective solution is to find different sources of fuel to power our day to day lives. The earth is in need of renewable, effective, and long lasting fuels. Global warming can be slowed through the use of renewable energy as it is versatile, clean, a good investment, and can easily be put into place in several different climates and environments.
The problems associated with climate change are mainly due to the combustion of fossil fuels. It is difficult however to stop this problem. The solutions of being more energy efficient, and improving emissions-control technology, can help lessen the environmental damage done by fossil fuel use they ultimately only alleviate the pressure of increase of pollution and affluence(Delucchi, Jacobson 31).
There needs to be a reduction if not extinction with the increasing amounts of carbon dioxide, methane, chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), per-fluorocarbons (PFCs) and nitrous oxide into the atmosphere because it is directly affecting global warming. The combustion of fossil fuels and greenhouse emissions mainly contribute to the increase of these gases. The longer we go without solving this global problem the more conflicts we will have in the future. Although global warming does make the earth warmer there is more to worry about than heating to death. Major concerns revolve around effects on agriculture, water resources, ocean level and coastal regions, and disease. Many scientists and experimenters still disagree with global warming using excuses such as ‘primitive’ climate models, which predict global warming trends, can not accurately simulate the Earth; it is too difficult because there are thousands of variables to consider. With the issue of global warming alternative sources of energy are looked for. “Data indicates that hydrogen is [the] only suitable future fuel.” (Williams, 102). Many scientists agree, but how long will it take for us to get there?
