Informative Speech On Global Warming

Improved Essays
Working Outline
Purpose: Informative Speech
Specific Purpose: Awareness of the threat of global warming
Introduction:
I. In the words of Leonardo DiCaprio after receiving his Oscar, “Climate change is real. It is happening right now. It is the most urgent threat facing our entire species, and we need to work collectively together and stop procrastinating.”
II. While many of us have heard about global warming, we do not view it significantly important as we all should. Global warming is defined as the increase in Earth’s average surface temperature and due to significant climate changes recorded by scientists taking place as of late and in years past, it is becoming a cause of concern.
III. The affects from global warming are hurting Earth in a negative way and it is mostly due to the release of greenhouse gases (GHGs) into the atmosphere by human-fueled activities. Therefore, it should be a cause of concern to all of us because it has significant effects on both natural environment and human life. IV. Due to having done my research and using valid sources upon this topic I am aware of the threat of global warming and today I will be informing everyone the effects of concern that are causing it to become a major issue. V.

With that being said I’ll begin by discussing what is causing global warming to take place right before our eyes.
Body:
I. To put it bluntly, the cause of global warming is human activity, primarily the burning of fossil fuels like oil, coal, and natural gas.
a. These are the significant driving factors in global warming. According to Global Warming from Encyclopedia of Global Warming and Climate Change “Many human processes ranging from industry, transportation, power stations, agriculture, fossil fuel development and usage, to residential and commercial activities have variously led to the production of high amounts of greenhouse gases.”
b. For centuries, the production and absorption of carbon dioxide and other greenhouse gases was in balance. But in the last century, human activity has overwhelmed the Earth’s natural feedback mechanism. As a result it has caused global climate change which is taking place and effecting the environment.
II. Climate change is already beginning to transform life on Earth. Around the globe, seasons are shifting, temperatures are climbing and sea levels are rising. According to Justin Gillis of the New York Times, “scientists reported that 2015 was the hottest year in the historical record by far, breaking a mark set only a year before.” a. As it continues some areas of the earth will become wetter, while others will experience heavy droughts. Since warmer air brings heavier storms, there will be an increased chance of stronger and more life-threatening storms. b. As temperatures rise globally, droughts will become more frequent and more severe, with potential devastating consequences for agriculture, water supply and human health. As northern countries warm, disease-carrying insects migrate north, carrying viruses with them that we have not yet built immunity for. NASA states in an article about global climate change, “Southwest region will experience increased heat; drought and insect outbreaks, all linked to climate change, have increased wildfires. Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal areas are additional concerns.” It’s accurate for our region and it will just continue to get worse in due time if changes aren’t

    How Human Activities Affect Global Warming Do human activities affect climate change, and as a result create global warming? Some scientists say no, but the majority of scientists say yes. They say human activities such as deforestation, using hydro-carbons, and burning fossil fuels, cause a lot of carbon dioxide to be released into the atmosphere changing the temperature of the climate, causing global warming. So now which group of scientists is correct?…

    Simply, it is the rise in the average temperature of the Earth’s climate, and we can’t deny the fact that the Earth’s temperature is increasing. Even a minimum rise in temperature of the earth’s climate has catastrophic effects. Global warming is caused by greenhouse gases which trap the sun rays inside the earth’s atmosphere, increasing the temperature on earth. As mentioned in a quote, “Human activities have added greenhouse gases to the atmosphere” (National Academy of Sciences B2) science proves human activities are the main cause of global warming. But, there have also been comments arguing that human activities are not the cause of climate change.…

    It's evident that temperature is rising which as a result causes us to experience a lot of abnormal climate changes worldwide. The cause of this increase of temperature is the greenhouse effect. The greenhouse effect is constructed by water vapor, carbon dioxide, methane and ozone. The greenhouse effect is when the gasses trap the sunlight, not making them bounce back to space, which creates the atmosphere to warm, thus making Earth hotter. What’s responsible for realising a large amount of carbon dioxide is the burning of fossils fuels.…

    The issue my group and I are discussing about is global warming. Global warming is described as an increase in the earth’s average temperature that is caused by an increase in greenhouse gases such as carbon dioxide and methane. Scientist have labeled humans to be the main cause for global warming. We believe global warming is a problem because it causes the sea level to rise, extinction of animals, and pollution. Most scientists agree that humans are the main reason for the development of global warming.…

    In Leonardo Dicaprio’s speech he said, “A world that we collectively felt in 2015 as the hottest year in recorded history. Our production needed to move to the southern tip of this planet just to be able to find snow. Climate change is real, it is happening right now. It is the most urgent threat facing our entire species, and we need to work collectively together and stop procrastinating.” Climate change may not be the biggest issue in the world, but it is a problem and is most definitely real and is affecting people and animals and if nothing is done now we will have an even bigger problem in the future.…

    Human economic activities, accelerated by globalized trade, contributing to an increase in average global temperatures. Primary cause is an increase in “greenhouse” gases such as Carbon Dioxide (CO2). The levels CO2 gas have risen to levels human mankind has not measured before. CO2 emissions occur as a by-product of virtually every type of economic activity, from car exhaust gases, energy production, industrial production, or livestock farming. As a conclusion, warmer average temperatures thus lead to a change in climate.…

    Global warming or climate change is the gradual increase of Earth’s temperature over time, through the greenhouse effect. The greenhouse effect is the rising carbon level in the atmosphere, trapping radiation, and heating the Earth. Humans are depending on fossil fuels that release these emissions. Though we have increasingly started depending on renewable resources that don’t release these harmful gases into the atmosphere, we can already see the effects today and if this doesn’t stop now the planet will be destroyed. The human intervention that people have depended on with the environment is destroying the Earth.…
