Global Warming is an important ecological issue and has many negative effects upon our environment. However‚ for all the attention that this issue does not draw‚ that is how dire it is growing to be. There are many problems that are causing global warming‚ and if they are not corrected‚ or at least prevented from here on out‚ there are going to be some severe complications in the near future. Greenhouse holes in the ozone layer and the decay of the atmosphere are just a few of the problems that need

An Inconvenient Truth‚ Al Gore’s lecture on global warming was very amusing. I liked the way he presented the lecture and by encouraging the people to act to solve this global crisis. Global Warming. What is global warming? Global warming is the increase in the average temperature of Earth ’s near-surface air and oceans since the mid-20th century and its projected continuation. Global warming is the world’s main problem. A graph was shown during the lecture pertaining to the ten hottest years ever-measured

the years? “Global warming” refers to the global-average temperature increase that has been observed over the last one hundred years or more. But to many people‚ the term carries that mankind is responsible for that warming. Global warming is a man made problem that has been progressing over the years and is getting worse and worse. Believe it or not‚ very little research has ever been funded to search for natural mechanisms of warming…it has simply been assumed that global warming is man made

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

PERSUASIVE SPEECH ON GLOBAL WARMING by: Jennifer Zelmer Introduction: We all know about global warming‚ but do we really care or try to do at least some of the things that will help stop it or at least slow it down? 1) Over the last century our planets temp. has risen 1 degree. I know that doesn’t sound like much but it’s been enough to melt a lot of the polar ice caps and glaciers. A) The hottest years ever recorded were in the late 1990’s and early 2000’s. B) In 2007 there was

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

Global Warming - Fact or Fiction? - Speech The Earth is rapidly heating up or is it? If it is‚ the next few decades may witness Biblical scenes of rising temperatures‚ crop failures‚ flooding and the extinction of different species. On the other hand‚ increases of Carbon Dioxide in our atmosphere may well encourage plants and trees to thrive like never before. Whom can you believe? One thing is certain the debate on climate change and Global Warming is heating up. It is surely right for

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

Global Warming Debate Today we are debating the important topic of global warming. As the affirmative team‚ we strongly believe that global warming is caused by the actions of humans. But this is not just a belief‚ this is a fact. Global warming‚ by definition‚ is a gradual increase in the overall temperature of the earth ’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide‚ CFCs‚ and other pollutants. The greenhouse effect is the trapping of the

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
