Global Warming: A Natural Process
The Earth’s current CO2 level is at 393.84ppm (CO2now, 2013). This is the highest of the high levels in the past 450,000 years. Extra carbon dioxide in the air is believed to keep temperatures steady and contributing to the greenhouse effect which causes the planet to warm. Scientists believe that humans add CO2 through the burning of fossil fuels, deforestation, and livestock farming to name a few. Natural processes also contribute to the CO2 emitted into the atmosphere including forest fires. Two sources on Earth remove CO2 from the atmosphere: Trees and the ocean. Deforestation can contribute to global warming because trees absorb carbon dioxide and when trees are removed the Earth loses its…show more content…

Global Warming: A Natural Process
The Earth’s current CO2 level is at 393.84ppm (CO2now, 2013). This is the highest of the high levels in the past 450,000 years. Extra carbon dioxide in the air is believed to keep temperatures steady and contributing to the greenhouse effect which causes the planet to warm. Scientists believe that humans add CO2 through the burning of fossil fuels, deforestation, and livestock farming to name a few. Natural processes also contribute to the CO2 emitted into the atmosphere including forest fires. Two sources on Earth remove CO2 from the atmosphere: Trees and the ocean. Deforestation can contribute to global warming because trees absorb carbon dioxide and when trees are removed the Earth loses its natural carbon storehouses. Phytoplankton consume CO2 through the photosynthesis process and transport it from the ocean’ surface to the deep. These sources eliminate 30-50% of carbon dioxide in the atmosphere.
Global Warming For decades scientists have claimed that the Earth is undergoing global warming caused by human activity, primarily the burning of fossil fuel. However, one can look back through history to see that global warming is a natural cycle. The Earth routinely goes through a process of cooling and warming. Approximately, every 100,000 years there is a documented spike in temperature on Earth. Historical data indicates that when this spike occurs there is an increase in CO2 levels.
The Earth has been experiencing a

Essay about Global Warming: Why It's Happening

1279 Words6 Pages

Global warming has been a hot topic for generations. Questions like "Is it natural or man-made?", "What is causing it?", or "How can we reduce it?", have stumped scientists and engineers. Most people think that reducing global warming means having to buy expensive "green" contraptions or driving electric cars, that can be dangerous, due to their size, and can take hours to charge. Those would be great things to do to reduce our impact on global climate change, but unfortunately, in our current economic state, most people don't have that kind of money. Fortunately, there are effective and cost efficient ways to reduce global warming and live a cleaner, greener and healthier life. There are many theories as to why global warming is…show more content…

Those would be great things to do to reduce our impact on global climate change, but unfortunately, in our current economic state, most people don't have that kind of money. Fortunately, there are effective and cost efficient ways to reduce global warming and live a cleaner, greener and healthier life. There are many theories as to why global warming is happening. Some, point more towards the theory that humans might be causing it, and others point more towards the theory that it is a natural cause, but one thing is for sure, the climate is changing and if we don't do something soon, the Earth my face harmful, and even deadly consequences. Scientists have seen a rapid increase of Average Global Temperature in the past century. They have concluded that the Earth has increased approximately 1 degree Celsius (about 3 degrees Fahrenheit) in the last one hundred years. According to the film “Six Degrees: Could it change the word?” experts are predicting that the Average Global Temperature could increase six times that amount at the end of the current century, at our current rate of
