II. Global warming is caused by greenhouse gas emissions which contribute to global warming. The evidence is overwhelming that the Earth 's surface is warmer today than it was a century ago. As for why this is so, research by thousands of scientists strongly suggests that the cause is the largely uncontrolled and still increasing release of anthropogenic (human-caused) greenhouse gases. (Jordan, Stuart) A meteorological consultant argues that human-caused CO2 emissions are not impacting global temperatures. "Keep in mind that CO2 represents 0.0395% of the Earth 's atmosphere. Arguing that CO2 is driving the small temperature variations in our climate as opposed to the oceans, which cover 70% of the planet and have 1,000 times the heat capacity of air, or the output of our sun, is scientifically disturbing." Some people argue that there aren 't consistencies in climate science, and that carbon dioxide emissions cannot be solely attributed to global warming. "Repetition of a fib does not make it true. As one of many pieces of evidence that our climate is doing what it always does, consider the National Oceanic and Atmospheric Adm...

Now that you understand global warming it may seem possible for us to reverse the effects of global warming. Today, I have emphasized certain points of global warming, including its causes, effects, and solutions. I have discussed with you what causes global warming. I have also shared with you some of the current effects of global warming. Finally, I have informed you of some solutions to reduce it. Hurricanes, heat waves, flooding, and droughts stirred some fears in global-warming skeptics and corporate allies that used to mock global warming--such as Detroit 's Big Three automakers and oil giant Texaco--have, like the glaciers, melted away from the fight.

- The Causes, Effects and Possible Solutions to Global Warming Global warming is a problem that threatens the whole world. Though it has had little noticeable impact on the world so far, its potential impact could be disastrous which is why global warming has become an issue ever present in the media and for governments. Global warming is not a new phenomenon. The sun warms the Earth's surface and to stop it over-heating the heat energy is radiated back through the atmosphere and into space....

- Abstract There needs to be a reduction if not extinction with the increasing amounts of carbon dioxide, methane, chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), per-fluorocarbons (PFCs) and nitrous oxide into the atmosphere because it is directly affecting global warming. The combustion of fossil fuels and greenhouse emissions mainly contribute to the increase of these gases. The longer we go without solving this global problem the more conflicts we will have in the future. Although global warming does make the earth warmer there is more to worry about than heating to death.... [tags: Environment Ecology Earth Climate Change]

- The planet earth is in serious jeopardy due to global warming. The polar ice caps are melting at an astonishing rate. Severe flooding and droughts are creating havoc around the world. All nations must begin to address, formulate, and implement the necessary solutions to reduce global warming before it becomes irreversible. Developed countries can drastically reduce the emission of green house gasses (GHG) which are destroying the ozone layer by reducing the destruction of rainforests, switching from electric generating power plants that are burning fossil fuels, to electricity generated by wind technology, and reducing the amount of carbon dioxide (CO2) emissions from vehicles....

- Global Warming has been a nuisance to environmentalists in recent years. It has been affecting Earth’s oceans, habitats, and biodiversity. Over the years, scientists have conducted experiments to understand the causes and effects of global warming and they have searched for solutions. They have warned others about the dangers of pollution and human activities and have urged others to do something about it. Films, such as Al Gore’s documentary “The Inconvenient Truth”, have also raised international public awareness of climate change and have re-energized the environmental protection movement; however, some politicians, government officials, and scientists have opposed this theory....

- Over the years it has been observed that the temperature of the earth has been getting warmer and warmer. Many would simply shrug this off as fluctuation in the weather, but this has been proven to not be the case. This effect is known as global warming, and the effects associated with it is called climate change. Global warming is not simply caused by one thing. Multiple things cause global warming, but there is one main culprit, carbon dioxide. Carbon dioxide is a gas used by plants to undergo photosynthesis....

- Many change and influences are being been concerned since average temperature has changed. While global warming is occurring, global temperatures and climate patterns are changing across the entire world. That some effects started appearing across a spread of countries is a result of human activities such as burning of fossil fuels, deforestation, and agriculture result in climate change all of the problems can be addressed by reducing energy consumption, curbing clear logging, and eating less meat....

- You hear about it from television news broadcasts. You read about it in newspapers and magazines. You talk about it with friends and co-workers. There have even been movies made about it. The “it” is global warming. “Global warming refers to the global-average temperature increase that has been observed over the last one hundred years or more” (Spencer). Some experts argue that global warming is a result of human activities, while others believe the warming and cooling of the Earth’s atmosphere is a natural cycle....

- Climate change is a controversial subject that needs further investigation to conclusively prove to others that a problem exists. Even those trying to prove climate change will admit there are multiple variables that can affect the planet’s climate and many of those are not man-made. As stated in the introduction to chapter 12, “2013: Long-term Climate Change: Projections, Com¬mitments and Irreversibility”, of the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (AR5) by Collins et al....

- Global warming has been one of the leading environmental issues for the past several years. Global warming is when an excess of certain gasses are produced and trap the sun’s heat in the atmosphere. One of the most abundant of these gasses is carbon dioxide. It is released when fossil fuels and other things are burned for their energy. The average American family of 2 will produce 41,500 pounds of carbon dioxide per year. The Earth is able to cope with a certain amount of these gasses otherwise known as greenhouse gasses.... [tags: essays research papers]

- Pollution in our world is leading to increased global warming. Global warming is a problem that if it doesn’t effect us, it will effect all future generations. Global Warming is a problem that all of us can solve, and it should be solved through the work of our community. Global Warming is caused by the Greenhouse Effect. The Greenhouse effect causes the sun’s rays to come in the earth’s atmosphere, and when it bounces back, more and more of the sun’s rays stay in the Earth, heating up the average global temperature....
