Introduction:
There has been a continuing argument whether humans are the main cause if Global Warming or if it’s a natural process of the earth. In this speech, we will discuss both sides of the arguments, the impact and come to a final decision. Global Warming is the average temperature around the world that is rising. Green house gases are the main culprits of Global Warming, which are the gases that trap heat around the Earth. The present situation of the Earth caused by Global Warming is that the temperature will rise from 0-6 degrees which will impact the poles. The enhanced greenhouse effect is an increase in the concentration of greenhouse gases in the atmosphere. This information was from http://jncc.defra.gov.uk/page-4389
Natural Causes:
Global Warming is not all down to humans, there are also natural causes for Global Warming. One of the natural causes are, when a volcano erupts it releases large amount of ash and Sulphur dioxide into the stratosphere, which is the layer of air 10-50 kilometres above the earth’s surface, we call this layer the cloudy layer. Once the ash reaches the stratosphere it will evenly spread. The ash acts as a shade for the earth but it will cool it by 0-1˚C and only last a few years, this information was taking from http://www.skepticalscience.com/Stratospheric-Cooling-and-Tropospheric-Warming.html
Human Effects:
Global Warming is thought to be mainly a human cause, this is because, before we stared impacting on Global Warming, the Earth’s natural processes impacted it and balanced it out with trees absorbing the carbon dioxide. Since humans have started to impact Global Warming, with carbon dioxide, with many different things. Through human activities such as deforestation, creating cement, and burning fossil fuels. Humans have increased impressive CO2 concentration by a third since the Industrial Revolution began. This is the most important long-lasting "forcing" of

fuel, deforestation and carbon dioxide, which traps heat that would otherwise escape from the Earth (NRDC, 2005). Global Warming can bring severe change to the atmosphere that could result into loss of human, animal life and natural resources significantly. In 2007, the United Nations released a report that stated that global warming is happening and will continue for centuries to come (Shariff & Karachi, 2013). The report stated that the activity of humans is the primary cause of the increase of temperatures…

Global Warming Research Paper

warming exists. It exists because of society’s everyday habits to use natural resources at an increasing rate. We must do something about it or our planet is “doomed” so to speak. Our world is a very finite planet on which we run a linear system (Annie Leonard). In other words, planet earth has limited natural resources; we are using those natural resources up more and more at a steady, increasing rate each year. By using these natural resources we contribute to global warming on the daily. Global warming…

atmosphere. The average amount of carbon dioxide in ppm (parts per million) for the past 800,000 years is 230 (CO2 Now). As of April 2013, the amount of CO2 in our atmosphere is 398 ppm according to the Mauna Loa Observatory (CO2 Now). This increase is owed entirely to anthropogenic (resulting from human influence) reasons. The environment has always been a very balanced system that included element cycles and sinks for different compounds. An environmental sink is a natural container of different elements…

The Importance Of Global Warming

Geography Greenhouse Effect: the result of the sun's heat being trapped within the atmosphere rather than reflected out into space. This causes a significant increase in temperature. The greenhouse effect is a natural process. Without the atmosphere, the Earth's surface would be about 15*C cooler then it is now. Enhanced Greenhouse effect: increased ability of the Earth's atmosphere to trap heat, warming the earth and the atmosphere. Humans have contributed with high CO2 emissions. Such…

Global Warming Essay

is a threat to us socially, economically, politically, and immediate actions should be taken to minimize it. Whereas, other people say that global warming is beneficial and is a natural process that is required for the sustainability of life on earth. Hence, in my opinion, global warming is a potential threat that causes harm not only to humans, but also to the planet as a whole. Global warming can be defined as the increase in earth’s average temperature caused by the excessive rise of greenhouse…

components interact in biogeochemical cycles? Describe both the carbon and nitrogen cycles Carbon is the seat of energy storage and tissue building in living organisms. The carbon cycle in coral reef starts with respiration, which takes carbohydrates and oxygen and combines them to produce carbon dioxide, energy and water as a result. Afterwards, the process of photosynthesis produces carbohydrates and oxygen out of carbon dioxide and water. “Photosynthesis by diverse plant forms (from unicellular…
