Global Warming: Are Humans to Blame? Kelly Gaffney October 10‚ 2011 SCI 207 Instructor Reale In order to understand the issue of global warming (also referred to as climate change)‚ you must first understand what it means and how it happens. Global warming is a result of a process known as the greenhouse effect‚ in which the light and heat from the sun are trapped in the Earth’s atmosphere by greenhouse gases; which subsequently raises the average temperature on Earth. The greenhouse

Cause and effect of global warming Global warming occurs when the levels of greenhouse gasses rise and less infrared light‚ or heat‚ escapes the earth ’s atmosphere. Thus‚ the temperature experienced on Earth begins to rise. Climate change is a part of the Earth ’s history. There have been dramatic fluctuations in overall average temperature for the past 150‚000 years that suggest a direct association with carbon dioxide levels. In the past the temperature highs and lows have been in tandem with

SUMMARY Global warming is the increase in the average temperature of the earth’s atmosphere. It happens when high level of greenhouse gases like carbon dioxide and methane are trapped in the atmosphere causing a rise in temperature. Although the idea that global warming is similar to climate change‚ there are still some distinctions with these two concepts. As mentioned earlier‚ there is a shift from low temperature to high temperature caused mainly by gases when we speak of global warming. While

If you don’t know what Global warming is it is the increase in the earth’s average temperature due to the release of several greenhouse gases into the atmosphere by humans. Global warming is affecting many different parts of the world and in turn causes a cause and effect. Glaciers are melting which is causing the sea level to rise. When the sea level rises it causes damage to people living in low lying areas‚ and damages to plants by covering them which causes them to die. Which in turn causes animals

Is Global Warming a threat to the Human Population? Global warming has been a lot in the media and most people have probably discussed it and feared it for an amount of years now. In the media‚ Global Warming has been presented as a catastrophic event that will change the world as we know it‚ and have disastrous and horrible effects on us‚ and that it might be our demise. At first‚ scientists believed Global Warming to be a result of too much human activity‚ but as they years have passed and

Billy Joel once said‚ “we didn’t start the fire”. He is right; global warming is a natural cause. The Earth was heating long before humans were emitting large amounts of greenhouse gases and even before humans were on planet Earth. Since humans were not alive during the period after the ice age (known as the post-ice age era)‚ then the heating of the Earth to melt the ice does not put humans at fault. Global warming is naturally caused by natural emission of greenhouse gases‚ Earth’s heating and

Air Conditioning and Global Warming Air conditioning systems use energy to remove heat from a given location‚ transferring it to the exterior in the form of exhaust. Some of the energy is invariably wasted as heat‚ and this additional heat must also be exhausted. Thus‚ air conditioning results in net heat release to the environment. The warming effect is aggravated‚ moreover‚ because higher forms of energy such as electricity are used to power air conditioners. Generating and transmitting this

GLOBAL WARMING – CAUSES AND EFFECTS Global warming is defined as an increase in the average temperature of the Earth’s atmosphere. It is one of the most serious issues that the world is facing today. This essay will discuss the main causes and effects of global warming. One of the main causes of Global warming is the carbon dioxide emissions‚ which comes from the burning of gasoline from the engines of cars‚ buses and other vehicles. Ho Chi Minh city in Vietnam is considered to be the most seriously

Describe the strategies that have been suggested to reduce global warming. To what extent do you think they are successful? Global warming is the rise in the average temperature of Earth’s atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century‚ Earth’s mean surface temperature has increased by about 0.8 °C. It is primarily caused by increasing concentrations of greenhouse gases like carbon dioxide and methane produced by human activities such
