Global Warming Speech
The global warming speech you will find below discusses a topic close to the hearts of many of us.
In fact, it's a topic that is likely to remain current until measures designed to protect the environment are seen to be having a positive impact.
Beginning of Global Warming Speech
"That so many of us are here today is a recognition that the threat from climate change is serious, it is urgent, and it is growing. Our generation's response to this challenge will be judged by history, for if we fail to meet it - boldly, swiftly, and together - we risk consigning future generations to an irreversible catastrophe."
These are the words President Obama used to begin his global warming speech before the United Nations Summit in 2009.
Search Google for global warming and you will get almost 65 million pages of results.
The subject has certainly drawn a lot of attention. But just what is global warming? What is causing it? What effects does it have on the earth and its inhabitants? What are some possible solutions? These are the questions that I will be addressing in this short, informative speech today.
What is Global Warming?
Global warming is the gradual increase of the temperature of earth's atmosphere and oceans.
Over the past century the average temperatures have gone up by just over one degree. This may not seem like much, but many scientists agree that the earth's temperatures are starting to increase at a faster rate.
What Causes It?
Global warming occurs when greenhouse gases, such as carbon dioxide, nitrous oxide, and methane trap heat inside the earth's atmosphere.
Think about what happens when you open your car door after the windows have been rolled up on a hot day. Heat from the sun enters the car, but the frame of the car prevents it from escaping.
To a small extent, this is a representation of what happens during global warming. Burning fossil fuels like petroleum and deforestation both contribute to the problem.
What Effects does Climate Change Have on the Earth and its Inhabitants?
Global warming has already started to affect the earth in several ways.
Arctic glaciers have begun to melt, threatening indigenous life such as the polar bears. Melting glaciers also cause sea levels to rise. This could become a problem for low land areas like the ones in the South Sea Islands.
Ocean temperatures have begun to rise. This causes some of the algae to die which can affect the entire food chain.
What are some Possible Solutions to the Problem?
There are ways we can combat the effects of global warming. The Clean Air Act of 1990 is a law in the United States that attempts to protect and improve the earth's air and atmosphere.
Some of the components of this law include limiting harmful vehicle emissions and phasing out the use of chemicals that can damage the ozone layer.
On a more personal level, we can work to prevent global warming by planting trees and by car-pooling.
Climate change is seen as a serious threat that is receiving serious attention world-wide. Hopefully, this global warming speech has helped inform you of what causes it and the effects that it has on the earth. It's up to you to decide how you can help to do something about it.
End of Global Warming Speech
This speech isn't written to persuade or motivate the audience to do anything about the effects of global warming. It is an informative speech, only meant to give the facts.
If you are really passionate about the subject you may want to turn it into a persuasive speech on how people can help to minimize the damage to the planet we engage in every day.
Watch the video on your right to see what the President of the USA has to say about climate change and where he sees it heading in the future.
His talk would be considered a persuasive speech on global warming.
If you want to get controversial, on the other hand, you may want to give a speech on how climate change is a hoax! Do a little research and you'll find there are many people who seem to think it is.
Whichever way you want to go, you can use this global warming speech as a starting point to create a presentation of your own.

Respected dignitaries on and off the stage, teachers and my dear friends
Today I am going to talk about one of the greatest problem humanity is facing right now, which Global is warming.
Global warming is a phenomena in which there is a gradual increase in the average temperature of the Earth’s atmosphere and its oceans. This change is believed to have serious implications on our planet and is permanently changing the Earth’s climate. This can be also seen as an implication of man’s greedy nature and the over exploitation of our mother nature in the hunt for more and more resources. For centuries we brutally exploited our resources, thoughtlessly wasted it and reaped profits without a thought about our future generations. Over the last century, global average temperature has increased by more than 1°F or 0.7°C .Global warming is primarily a problem because of too much carbon dioxide in the atmosphere which acts as a blanket, trapping heat and warming the planet more and more. As we burn fossil fuels like coal, petrol, diesel and natural gas for energy or cut down and burn forests to create plantations, carbon accumulates and overloads our atmosphere. Certain waste management and agricultural practices aggravate the problem by releasing other potent global warming gases, such as methane and nitrous oxide. A warming world also has the potential to change rainfall patterns, increase droughts and severe storms, melt glaciers, increase sea levels, and even change plant and animal behavior. Today we have substantial scientific evidence which indicates that an increase in the global average temperature of more than 2°F above from where we are today poses severe risks to natural systems and human health and well-being. The world has already realized the potential aftermath of Global warming and have started massive campaign to reduce its effect. There is no single solution to global warming. But a multi faced approach like focusing more towards clean and green energy production, increasing the efficiency of the current systems, gradual facing out of the fossil fuels, prevention of deforestation and ensuring sustainable development etc. are some of the ways ahead. Countries around the world have been submitting their pledges to the United Nations, setting out how far they intend to reduce their greenhouse gas emissions over a period of time.
As students, we also can play a major role in compacting global warming. Despite of the great threat it possesses, our society is still not aware of it. The war against global warming will be effective if and only if a common man realizes that he is also contributing to it when he even forget to switch off electricity after the usage. As the future scientists and decision makers, lets take a pledge towards focusing and developing more sustainable technologies .We can also conduct campaigns to increase the awareness and the need to respect our mother nature. Its interesting to note that even a reduction in meat consumption by humans can help in compacting global warming. .Our resources are precious and it belongs to all, primarily for our survival and not for luxuries.The world can survive without mankind but mankind cannot survive without this world.
