Are Humans Responsible for Global Warming? A REVIEW OF THE FACTS APRIL 2007 AUTHORS James Wang‚ Ph.D. Bill Chameides‚ Ph.D. Are Humans Responsible for Global Warming? The case for attributing the recent global warming to human activities rests on the following undisputed scientific facts: • Carbon dioxide (CO2) is a greenhouse gas that warms the atmosphere. • Since pre-industrial times‚ atmospheric CO2 concentrations have increased from about 280 parts per million (ppm) to over 380 ppm. Current

Global warming is leading the world into a point of no return. Humans have been modifying the environment exponentially‚ and since the industrial revolution the “carbon dioxide in the atmosphere has increased by about 35%” (Le Treut 97). Who is the responsible of these changes‚ how do we know they are true‚ and how does these changes would impact our living in the future? This carbon dioxide increase is known to be mainly caused by the deforestation of forests‚ and the combustion of fossil fuels

Introduction: The view that human activities are likely responsible for most of the observed increase in global mean temperature ("global warming") since the mid-20th century is an accurate reflection of current scientific thinking. Human-induced warming of the climate is expected to continue throughout the 21st century and beyond. In contemporary times‚ there are several ways in which the human race is at risk. One of these risks includes the rising global temperature greatly impacted by gases

Global warming and can it be prevented Name SCI 207 Instructor Date Global warming and can it be prevented We have to face the fact that global warming is now a part of the planet‚ and may be due to the actions of humans making it human-caused. One of the causes of global warming is greenhouse-gas effect. It will continue for centuries even if and when greenhouse-gas emissions are stabilized in the future. Humans are helping to cause global warming by "Fossil fuel use‚ agriculture

Are Humans the cause of Global Warming? How do we know global warming is caused by humans? Can global warming just be a natural cycle for earth? Global warming is a major problem in the world today. Having a hole in the ozone layer isn’t quite beneficial for humans no matter what the cause. Global warming is an increase in the earth’s average atmospheric temperature that causes corresponding changes in climate and that may be resulted from the greenhouse effect. The global average surface temperature

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

Humans Are To Blame For Global Warming Kevin Odhiambo Ogwa Lake Michigan College Abstract Every human activity has a particular effect on objects surrounding his or her environment‚ be it physical‚ mental‚ or social. But notably‚ the most evident might be the effect of human activity on global warming. Global warming is quickly becoming a major topic of concern worldwide‚ and has been stirring up controversy everywhere with its adverse effects seen all over the world. It causes rise of the

The Human Factor of Global Warming The Human Factor of Global Warming Global warming has been a growing concern for many over the last several decades. The effects of global warming are evident and broad‚ with historical research dating the first global warming crisis back 56 million years ago‚ better known as the Paleocene-Eocene Thermal Maximum‚ or PETM (Jardine‚ 2011). Research from the composition of sediments of fossils shells of marine organisms conclude that carbon dioxide trapped within

Global Warming‚ Not Caused by Humans In modern America few problems prove to be as fundamentally problematic as the theory of human induced global warming. Its repeated coverage from within the media and political arena are influencing people worldwide‚ putting those who think differently in an outcast shadow. The truth of the matter is‚ to not believe in human induced global warming has become politically incorrect and unacceptable in the public eye. The theory of human induced global warming can

November 19‚ 2012 Outline Is global warming due to human actions? Can the human race take action to stop global warming? Introduction Thesis Statement: Yes‚ human actions are definitely a factor in global warming. The fact that there have been natural cycles of climate change since earth’s formation‚ in past and recent centuries humans have influenced global climate change through the emission of greenhouse gases. The actions that humans should take to stop global warming are to reduce the greenhouse
