What exactly is global warming and what is it doing to our planet? How are we to know that the effects will not cause harm to the earth and all the residents that live on it? Numerous questions arise and countless lies are sent out to answer these inquiries. Because there are many different opinions on this topic, often times they contradict each other completely. Some people believe that humans are causing it while others believe it is just another result of the trapped CO2 and methane. The Greenhouse effect, changes since the Global Warming and incorrectly presented statistics are all contradictions involved in Global warming.
What is the Greenhouse effect? It is warming close to the earth’s surface that happens when the earth’s atmosphere locks in the sun’s heat. Infrared radiation is sent back into the atmosphere which is heat energy. Too much infrared radiation causes an overheating but not enough to warm the earth by more than 1.5 to 2*F. Without the greenhouse effect, the earth would be too cold so it is necessary. The forests absorb gas but they are being destroyed. The Greenhouse gases are CO2 and CH4 (methane) and H2O (water). The CO2 and CH4 are transparent when they come to the earth but when they try to leave, the Ozone layer traps them in and they reflect the sun’s rays which warms the earth too much (World Book 383).
“The warming during the summer, which has the greatest impact on the stability of the ice shelves, has been linked to the ozone hole and increasing greenhouse gases” (British Antarctic Survey 1). Seeing the changes in polar ice and how its melting is easy to do but when people try to predict what is going to happen to the earth’s climate in the future, the facts get lost. The way it works is simply ...

...; that is a fact. It is something that is just part of the earth’s cycles. The earth warms and cools all the time but technology hasn’t been advanced enough to see the changes to recently. Scientists take the data they discover and they stretch it over the assumed age of the earth and say that is accurate even though in truth, it is only about 100 years of data they are basing their calculations on. The world will not reach a temperature so hot that people will die because of global warming. In I Thessalonians 5:21a it says “But examine everything carefully…” Look at all the facts and decipher which ones are legit. Also, a knowledge of topics that are prominent in the world today will help people understand the different angles of these issues. Though preventing the process completely may be impossible, slowing down the effects may help the planet be lovely longer.
Global warming is a scientific, political, and controversial topic. Some believe it is catastrophic, a slow moving killer hiding in the shadows. Others do not even think twice about it as they race by in a Hummer. Global warming is the gradual increase of temperature throughout different climates. It is caused by the greenhouse gas effect in which greenhouse gases, like methane and carbon dioxide, reflect sunlight back and forth. This reflected ultraviolet light bounces between the earth and the ozone layer and becomes trapped, resulting in a gradual rise of temperature. Over time, the slow rise of temperature causes new climates throughout the globe. The article “What Megablazes Tell Us About the Fiery Future of Climate Change” by Tim Dickinson
Global warming is an issue we are all pretty familiar with. It is the climate change that we, humans, are responsible for. The warming of the earth’s atmosphere is caused by the fossil fuels we burn, clearing of forests, and the carbon dioxide and other harmful gases we release into the air (Cunningham, Cunningham, 2009). There are other harmful toxins we use such as pesticides that are supporting global warming. Some effects of global warming include: increase in weather catastrophes, melting glaciers, rising sea levels, and the impact on species could lead to extinction (Cunningham, Cunningham, 2009). “Many scientists regard anthropogenic global climate change to be the most i...
One of the largest arguments about global warming is that it can’t be true because winters are becoming more severe. The counter argument to this is similar to the one about the Arctic. People use data from a certain area to dispute the truth behind climate change, another example of people looking past the big picture. Weather is a look at the atmosphere at a particular place and moment in time, while climate is over a long period. Having harsh storms and colder weather is a side effect of the warming oceans.
Greenhouse gasses have a big impact on our atmosphere. These gasses include water vapor, methane, ozone, nitrous oxide, and carbon dioxide. Each greenhouse gas molecule has three or more atoms that are loosely held together and that eventually release the heat energy and it is absorbed by another greenhouse molecule. Many people talk about greenhouse gasses as if they are a bad idea, but they are not a bad thing. Without these gasses the earth would be zero degrees on the surface. However, too many greenhouse gasses can cause higher temperatures in the atmosphere, cause oceans to warm beyond what they should be normally and weather that is unpredictable. The same with fossil fuels that produce a variety of emissions that pollute our planet 's air and water. These pollutants threaten the environment and its
First is a description of the greenhouse effect. The earth’s atmosphere has four layers, or zones, with each having distinct differences in temperature. The troposphere is the first layer surrounding the earth. Within this layer air is continually circulating and moving heat and moisture around the earth. The troposphere is denser than the other layers due to the fact that gravity keeps the majority of air molecules near the earth. This is about 75 percent of all the atmospheric mass. It is also the warmest layer (Cunningham & Cunningham, ...
The greenhouse effect is known as the rising in earth's temperature above from its normal temperature. In the atmosphere, there are certain gases, such as methane, carbon dioxide, nitrous oxides, water vapor, and ozone, which aid in this activity by reflecting the heat back to earth. Because of this process earth can maintain a suitable temperature. Around 57 degrees Fahrenheit, which are considered to be a normal temperature. The average temperature on earth would be zero degrees Fahrenheit, 18 degrees Celsius), if this radiation is not trapped, and as a result of life would not be as we are seeing now. In this way, these greenhouse gases are primary and very important for the survival of the living organisms on earth. What makes the earth,
An analogy of a greenhouse effect is the effect that you get when you go to the beach in a hot summer day and you leave your car with the windows closed. After you come back and open the car door you get a furnacelike blast of heat in your face. Inside the car everything is too hot to touch. This is similar to what the earth experiences when heat enters the atmosphere and is not reflected back.
Everyone needs to respire in order to live, which includes plants and animals. Trees and plants help to regulate the carbon cycle. When the trees take in the carbon dioxide from the environment, they give back to oxygen. When trees are cut down, there is a break in the carbon cycle, and there is no exchange in both oxygen and carbon dioxide which causes a spike in carbon dioxide levels. When these occur carbon dioxide moves in the atmosphere and stores there as a greenhouse gas. “However, deforestation still remains the second leading cause of greenhouse gas emissions, just behind industrial emissions” (Culas). Greenhouse gases disturb the normal regulation of the weather. When greenhouse captures and stores heat problems occur. When the carbon dioxide levels in the greenhouse gases are increased, then the atmospheric conditions becomes unstable, which causes global warming. Global warming is the increase in the temperature of the earth, which is mostly caused by the greenhouse effects. Global warming present itself by affecting the environment by causing drought, floods, change in ecosystem, less fresh water available and other environmental issues. Trees play a big role not only in keeping the soil rich, regulating the water table, providing a stable anchor for soil to lessen soil erosion and providing nutrient rich soil for agriculture but it also helps in the absorption of carbon emission in the atmosphere.
The subject of global warming is as popular as the president. These both topics have always been hot subjects in everyday life. Global warming is the biggest storm headed in our way. It is also the most important issue of our times. Those ads or public service announcement on TV about global warming might not be the most attractive but the cause behind it is very important. Global warming is one of the major threats our planet is facing. Most scientists prove the fact that global warming is mainly caused by human activities rather than natural cycles. To simplify it, most mechanisms that we use are affecting earth. These mechanisms are created by humans. Therefore, humans are affecting earth.
Global warming and the greenhouse effect are issues discussed by scientists all the time. A natural process that keeps earths temperature at a livable rate is called the greenhouse effect. The energy from the sun warms up the earth when the rays from the sun are absorbed by greenhouse gases. The gasses then become trapped in the atmosphere. Carbon dioxide, water vapor, methane and nitrous oxide are the most common greenhouse gases.
People say you don’t know what you have until it’s gone. Truth is, you know what you had, you just never thought you would lose it. The theme for the documentary “The Inconvenient Truth” by Al Gore and the article “Warm, Warmer, Warmest” by Kristof, revolves around trying to bring awareness on global warming and how it is human responsibility to act in attempt to stop global warming as much as they are provoking it. The purpose for both is to attempt to wake up the people about global issues. Both of their audiences involve everyone considering that humans are responsible for the on-going issue. For “The Inconvenient Truth” the tone tends to be serious but not as aggressive as it was for “Warm, Warmer, Warmest”. Al Gore in his presentation
Global Warming is a condition caused by greenhouse gases and human activities. The increased concentration of greenhouse gases due to activities such as deforestation and fossil fuel burning is causing the Earth’s atmosphere and oceans to warm up. As a result of this, global warming has some serious effects in the shape of extreme weather, species extinctions, and rising sea levels. These effects can contribute to the changes that are taking place all over the world, most of which are dangerous enough to pose a threat to the survival of life on Earth in the future.
Our planet has managed to survive and thrive for about 4.54 billion years. In the last 2 million years we have caused enough damage and destruction to make our world “broken” beyond repair. We will not be able to get back the world we once had. The reason behind this is global warming, specifically, the increase of the global temperature due to the burning of fossil fuels and the release of greenhouse gas emissions into our atmosphere. If we do not make the issue of global warming a priority in today`s society, our entire way of life will be at risk. There are many reasons why so many people believe global warming should be a concern. Thoroughly examined points include: scientific predictions, rising temperatures, human causes, drastic climate changes and animal adaptations. Though there are several points arguing how global warming should not be a concern, the reality of the matter is that it needs to be taken into consideration on a global scale before it is too late, as to do nothing would have devastating implications on humankind.
Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth's climate. While it changes the Earth’s climate it takes away different species that we depend on and some which other species depend on and also effect (in a bad way) the environment in which we live and can cause permanent damages to humans, animals, plant which will change the whole chain of ecosystem.
Global Warming One of the most substantial problems in the world today is global warming. This gradual warming of the earth is in occurrence at an extremely slow rate but it is happening. Many scientists believe that as human’s work and release greenhouse gases into the earth’s atmosphere, it can become dangerous for the long lasting life of humans and our environment. “Unless we take immediate action, the impacts of global warming will continue to intensify, grow ever more costly and damaging, and increasingly affect the entire planet - including you, your community, and your family” (“Global Warming Impacts”).
