The Human Factor of Global Warming - 2814 Words

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 our atmosphere, increased global temperatures by more than 5 degrees in just a few thousand years (Jardine, 2011). While global warming may not be in question, many scientists have questioned the actual global warming effect theory due to†¦show more content†¦* While humans might not be solely to blame for global warming, we definitely have a major role. Most are familiar with the burning of fossil fuels (coal, oil, and gas) as a major contributor to the overall C02, although, just as equally important is that of deforestation. It was realized that â€Å"conversions of land use, primarily deforestation in the tropics, induce substantial terrestrial carbon losses to the atmosphere, approximately 1.6 billion tons annually† (Broadmeadow, Freer-Smith, amp; J. Lynch, 2007). While the cause of deforestation varies in different regions, the key contributors are cutting down tree to open up more land for agriculture, urban sprawl (Turk amp; Bensel, 2011). Forests work like filters to remove CO2 from the air and store it in the trees. When the trees are felled or burned, huge amounts of CO2 are released into the atmosphere at a rapid pace. Urban Sprawl, a result of deforestation releases significant amounts of green house gases such as CO2. Not only do you have carbon dioxide being release from burning or cutting of forests, it is coupled by urban sprawl. It just so happens one of the effects of urban sprawl is that â€Å"Concrete production contributes 5 percent of annual anthropogenic global CO2 production, mainly becaus e such vastShow MoreRelatedIs Global Warming Due to Human Actions?

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 earths 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 greenhouseRead MoreThe Debate On Global Warming1239 Words   |  5 Pagescontroversy concerning global warming. The controversy takes the form of public debate that centers on five issues (Mazo 30). The first issue is whether or not global warming is occurring. The second issue is whether global warming is real and extent it has occurred in the recent decades. The third question relates to the causes of global warming. The fourth question centers on the effects of global warming. The fifth question is whether any action needs to be taken to contain global warming.

Human activities such as burning fossil fuels, deforestation, and emissions are held responsible for this situation developing. The climate change is the result, and a factor of global warming. There are several factors impacting global warming, and these include ozone layer depletion, carbon cycle, pollution, human actions, and orbit of the earth. There is a debateRead MoreGlobal Warming And Its Impact On Our Earth1676 Words   |  7 Pagesan abundance of factors that add to the destruction of our Earth.

Many scientists believe that global warming is natural while others believe it to be caused by mostly humans. Global warming may be completely natural for many reasons.

The greenhouse effect is a natural process that keeps the earth at temperatures that are livable. What does the greenhouse effect have to do with global warming? When humans release gases into the air, the greenhouse effect will alter the temperature of the earth. More gases in the atmosphere means the earth will start to get warmer, and the result is global warming. On the other hand, if
