Anthropogenic Global Warming - 1356 Words

Introduction Anthropogenic Global Warming Many consider global warming to be the largest threat that faces the earth today. This is just the opposite as we could not survive without global warming! The topic for this speech will be whether or not there is an imminent threat of Anthropogenic (or manmade global warming) at the end of my speech I would like the audience to develop the truce perspective on the issues of manmade global warming. This will be done through a small representation of the facts related to manmade global warming. To have a better understanding of what we’re exactly talking about in regards to the manmade global warming we will look at this chart.

The premise for anthropogenic global warming on the surface appears to be a plausible one. Humans through their need for fossil fuels take CO2 from underground and release it into the atmosphere where the sun’s ray’s heat the CO2 gases and generate more heat, the more CO2 we put into the atmosphere, the more the planet warms up. The fact is if we add up all of the manmade CO2 gases the percentages are quite small. We can see this percentage in the chart below as 1.0% of manmade contribution to global warming. With the greatest effect on the earth’s climate contributed to water vapor at 95%.

One is the Anthropogenic Global Warming (AGW) hypotheses which has become the most looked at theory. It supports the claim that climate change is due largely in part because of human activities. It also claims that human activity will eventually bring the world to an end. While the AGW is being argued there is also the issue of what is called the Kyoto Protocol which many scientists have urged theRead MoreGlobal Warming And Climate Change1713 Words   |  7 PagesDefining the Issue Global warming is defined as the recent increase in the world s temperature that is believed to be caused by the increase of certain gases (such as carbon dioxide) in the atmosphere. There are many different theories on whether global warming is similar or not to climate change. Simplistically, climate change is different because climate change is defined as a change in global or regional climate patterns or, in particular, a change apparent from the mid to late 20th century onwardsRead MoreThe Effect Of Temperature Increases Due On Anthropogenic Warming Change The Probability Of Precipitation Deficits That Cause Severe Drought Conditions? Essay1724 Words   |  7 PagesAbstract The purpose of this article by Diffenbaugh et.al. is to determine how temperature increases due to anthropogenic warming change the probability of precipitation deficits that cause severe drought conditions, and determine what the conditions will look like in the future. They used historical precipitation and temperature data with Palmer Drought Metrics and global climate models to attempt to answer this question. It was found that in the past twenty years, the frequency of drought yearsRead MoreThe Effects Of Global Warming On The Climate Change1405 Words   |  6 PagesGlobal warming, also referred to as climate change, has become a major political topic within recent years. Essentially, a controversial debate exists regarding the causes and subsequent impacts of global warming. Nevertheless, the current consensus by most experts is that evidence unequivocally supports the measurable impacts of global warming, such as increased temperatures, melting ice, etc. A literature revie w will be conducted in order to present scientific evidence that illustrates the impactsRead 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. The author concursRead MoreGlobal Climate Change.

If the answer were as easy as â€Å"yes, it is 100% caused by humans,† or â€Å"no it’s not at all caused by humans,† there would be very little room for argument. Two questions need to be investigated: 1) Is it probable thatRead MoreGlobal Warming Is Just A Natural Cycle?962 Words   |  4 PagesWhat if global warming is just a natural cycle? This argument is, perhaps, one of the most common raised by the average person, rather than someone who makes a career out of denying climate change. Cyclical variations in climate are well-known to the public; we all studied the ice ages in school. However, climate isn t inherently cyclical. A common misunderstanding of the climate system characterizes it like a pendulum. The planet will warm up to cancel out a previous period of cooling, spurredRead MoreGlobal Warming And Climate Change1131 Words   |  5 PagesPresident†). Warming temperatures caused by anthropogenic climate change have disastrous consequences that pose a threat to humanity and the environment. Scientists have given numerous warnings that human-caused, or anthropogenic, climate change is not only occurring now, but accelerating more quickly than predicted (Maibach, Myers, and Leiserowitz 295). Global warming contributes to climate change as a result of the release of greenhouse gases into the atmosphere (â€Å"Global Warming†). The levelRead MoreSummary : Finding On Ipcc Summary757 Words   |  4 PagesIPCC Summary for Policymakers, warming of the climate system is happening without a doubt, many of the observed changes have never happened before over decades to millennia and these changes were specially noted since the 1950’s. The consequences of these changes are reflected on the atmosphere and ocean which have warmed up, snow and ice have diminished around the globe, sea level has risen, and ultimately the concentrations of greenhouse gases have increased. Warming of the atmosphere was noted overRead MoreClimate Change And Global Warming1371 Words   |  6 Pagesdiscuss the processes that lead to climate change and strategies that can be used to address this issue. In order to comprehend how human activities contribute towards climate change and global warming, we have to truly understand the science behind this phenomenon. First of all we need to clarify what anthropogenic climate change means. This refers to the change in the amount of greenhouse gases and aerosols in the atmosphere as a result of unsustainable human activity. Greenhouse gases and aerosols
