Global Warming causes rising sea level from glacier melting, unusual weather, increased temperature, droughts and floods, changes in ocean currents and climate shifts. I believe that global warming is the human fault because humans create more pollution by burning fossil fuels, expanding the greenhouse gases and cutting down and burning trees also release carbon dioxide. Releasing such gases into the atmosphere not only effects the atmosphere itself but also effects the entire earth and its population. Global Warming is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth. This is a type of greenhouse effect.
The percentage of atmospheric carbon dioxide has risen over the past century at an alarming rate. Industrial civilization is essentially driven by fossil fuels such as coal, oil, and gasoline all major contributors to the raise in carbon dioxide emissions. Deforestation also releases carbon dioxide via burning and exposing the soil to sunlight. Also, since trees are a major factor in the natural processing of carbon dioxide, needing it to make up their mass, when they are cut down they can no longer serve to absorb carbon dioxide. Our practices are altering the environment and endangering society in return.
According to Union of concerned Scientists, the extreme weather events such as sea level rise, more frequent heat waves, and growing wildfire risks are the results of global warming. It is true that droughts are becoming longer and wildfire is increasing. I believe that human activities are warming our Earth and leading to increases in weather events. I think that one reason for this problem is the gas that is emitted by burning of fossil fuels to make electricity, and drive car. These gases are called greenhouse gases which include Carbone dioxide(CO2), Methane (CH4) etc.
Deforestation must also be stopped in order to give natural co2 scrubbers, plants, a chance to aid in the process. Governmental programs have also been implemented. A carbon tax has been considered along with the passing of the 1990 Clean Air Act, aimed at lowering emissions and cleaning air pollution. On a world wide scale, the Kyoto Accord in 1997, in which 159 nations agreed to work together to decrease Co2 emissions by 5.5% by 2012. The United States agreed, since it accounts for 25% of the worlds total emissions by 1990 figures, to cut its emissions by 7%.
"Greenhouse gases, which have built up to unnaturally high levels in the atmosphere, trap heat. They include carbon dioxide, which is emitted when fossil fuels are burned, and other gases produced by human activity"(Watson 2). These gases besides trapping heat, created a hole in our ozone layer which will continue to increase in size if the level of gases remain too high. A hole in the ozone layer means that there is no ozone to protect us within that given size of the hole. Whether the hole is big or small it does have an effect on earth which we call global warming, which in turn can have several effects on the planet.
As this carbon dioxide from burning fossil fuels enters the atmosphere, some of it is taken up by photosynthesizing plants, and the oceans absorb some. But because we are burning so much fossil fuel at such a rapid rate, we are putting carbon dioxide into the atmosphere much faster than these natural processes are taking it out. There is no longer a balance between the amount of carbon dioxide being added to the air and the amount of carbon dioxide being removed. As a result, the concentration of carbon dioxide in the air is steadily increasing. In conclusion, if we make small changes now in the way we live, we can avoid huge changes in the future.
To this end, this report aims mainly to discuss the causes and effects of global warming and propound some suggestions to solve this issue. 2. The causes of global warming 2.1 Fossil fuels burning One of the most significant causes of global warming is fossil fuels (coal, oil and gas) burning. According to Science (2013), the influence of recently fossil fuel use, even the most optimistic estimates suggest it will increase the temperature and affect the climate for tens of thousands of years. Each time burn fossil fuels for the electricity of cars, air plane or plant can produce plenty of carbon dioxide.
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. Global Warming due to Human Activity Every day human activity has negative effects on the environment. The burning of fossil fuels has released large concentrations of carbon dioxide (CO2) into the atmosphere. Developing countries such as China and developed countries such as the United States (US) are consuming more fossil fuel, thus releasing more CO2 from their admissions (Vital Signs 42).
Global Warming is an increase in the earth’s temperature due to the use of fossil fuels and other industrial processes, leading to a buildup of green house gasses. It has been known that using these gasses stops the suns heat rays from getting into space. This is called the green house effect. There is a question weather this adds to Co2 levels in the atmosphere. A rise in temperature could cause coastal folding and major climatic changes.
When fossil fuels are burned it is one of the biggest causes to global warming and climate change. The carbon dioxide level in the atmosphere is slowly rising due to the burning of fossil fuels. The United States, who is the leading consumer of fossil fuels are trying to find a successful way of reducing the need for fossil fuels especially gasoline. The effects that humans have on the earths atmosphere didn’t just recently happen, it’s happened before in the past. Our future generations will be affected more then the people who are experiencing the af... ... middle of paper ... ...rbon dioxide in tress helps build their tissues and return some of it to the soil.
