The greenhouse effect has heavy effects on earth. It has positive and negative effects on humans and the earth. The greenhouse effect is a natural process that warms the earth, and it is necessary for the survival of humans. The greenhouse effect helps warm the earth’s surface. Without it our planet would be too cold for humans to survive. Human activity has changed the concentration of certain greenhouse gases in the atmosphere since the beginning of the Industrial Revolution. The world, for all we know, may end sooner than we think.
Atmospheric scientists first used the term “Greenhouse-Effect” in the early 1800’s. It was used to describe the naturally occurring functions of trace gases in the atmosphere and did not have any negative connotations. In the recent decades, we often hear about the term greenhouse effect in somewhat negative terms. It is important to know that without the greenhouse effect life on earth as we know it would be impossible. In the atmospheric greenhouse effect, the type of surface that sunlight first encounters is the most important factor. Forests, grasslands, oceans’ surface, ice caps, deserts, and cities all absorb, reflect, and radiate radiation differently. Sunlight falling on a white glacier surface strongly reflects back into space, resulting in minimal heating of the surface. Sunlight falling on a dark desert soil is strongly absorbed and contributes to significant heating of the surface and lower atmosphere. Cloud covers also affect greenhouse warming by both reducing the amount of solar radiation reaching the earth’s surface and reducing the amount of radiation energy emitted into space. Although the greenhouse effect is a naturally- occurring process, humans have recently ampl...

It is being understood that these gases, greenhouse gases concentration, are increasing. One problem resulting among others is a warming of the earth’s surface, which results in increasing temperature, climate changes, and subsequently associated sea level rises. Rapid increases in greenhouse gas concentrations are due mainly to human activities like burning fossil fuels, deforestation, intensive agriculture, coal-mining, and rubbish dumps. The greenhouse effect and global warming should be taken more serious by many people. Humans cause this problem. Humans can also stop this problem. If humans keep increasing the heat in earth’s atmosphere, there may not be an Earth. Humans should stop doing all these things that make the earth heat up and start doing more to cool off the earth.
One of the greatest problems facing humanity is global climate change. Global climate change is the increase in average global temperature, caused by an increase in greenhouse gases. Greenhouse gases are the blanket of gases surrounding the earth that allows the world to be inhabitable. This layer of water vapor, carbon dioxide, methane, and other gases works. in the same way that a greenhouse does, by trapping heat energy inside the atmosphere.
The major effect most scientists fear as the result of increased levels of CO2 in our atmosphere is global warming. By blocking the heat reflected from the Earth's surface, greenhouse gases are able to warm the planet in a similar way to how glass warms up a greenhouse. Without this greenhouse effect, it is calculated our planet would be 35 degrees Celsius cooler worldwide, causing oceans to freeze and greatly altering life (Doyle, 1996). Accordi...
Global warming and global climate change is the study of future increases of temperature across the globe. Studying climate change refers to how the over- all climate will change such as the dry places getting dryer and the wet places getting wetter. Global climate is dependent on “the greenhouse effect a natural process that helps regulate temperature” (Easterling and Karl). In the past few centuries humans have had a monumental effect on increasing of greenhouse gases in the atmosphere. Climate change is result of the increase amount of the greenhouse gasses in the atmosphere such as methane, carbon dioxide, water vapor, nitrous oxide, and ozone. “Global temperature has rose approximately 1.4 degrees Fahrenheit over
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.
Jean Baptiste Joseph Fourier, a mathematician and physicist, discovered the concept of “global warming” in the 19th century while studying how Earth receives energy from the sun. According to his published theory in 1822, “General Remarks on the Temperature of the Terrestrial Globe and Planetary Spaces,” Fourier recognized how the sun’s heated energy, absorbed by Earth’s surface, and radiated back toward space, became trapped in the atmosphere by gases creating a lasting warming effect. He concluded the more gases in the atmosphere, the warmer Earth’s atmosphere became. Thereafter scientists used this theory as groundwork toward further research and coining the phrase “greenhouse effect.” (Fourier)
If there were too much greenhouse effect, the temperature of the Earth would rise. This is what is happening right now. Large amounts of fossil fuels are being burned, releasing tons of CO2 into the air. Too much greenhouse effect would lead to ocean acidification, desertification, and rising sea levels. Plant growth would be greatly reduced. Many storms and natural disasters would become more dangerous and destructive. Our food supply
Thesis statement: The global warming and the resultant climatic change is due to uncontrolled human exploitation of earth and its resources thereby emitting large volumes of greenhouse gases into the atmosphere.
The commonly debated “greenhouse effect” refers to “the global-average temperature increase that has been observed over the last one hundred years or more” (Spencer). President Barack Obama addressed the issue as an effort to highlight its severity, "We have to all shoulder the responsibility for keeping the planet habitable, or we’re going to suffer the consequences – together” (Leader). The earth’s increasing atmospheric and oceanic temperatures result in climate changes due to cumulative amounts of carbon dioxide (CO2) in the atmosphere.
Greenhouse gases cause the radiant heat of the sun to be trapped in the Earth's lower atmosphere, which causes global warming. If there weren’t any greenhouse gases, the earth would be really cold due to very little sun rays being absorbed into the earth. Global warming can and will lead to several problems that affect the environment in which we humans live. These problems can lead to warmer temperatures all around the world, it can endanger animals and the wildlife, and it can lead to widespread flooding from the glaciers melting. Here are a few more future effects that I will discuss in more detail.
Since the beginning of the existence of planet Earth, different eras have shaped the atmosphere of our planet. But recently, the inhabitation of mankind has changed the levels of Carbon Dioxide in the atmosphere, on a rather unhealthy scale. Because of our emissions, we have given global warming no other path then to rise. The increased amounts of Carbon Dioxide and other gases put into the air are enhancing the greenhouse effect. The greenhouse effect, the trapping of the sun's warmth in the planet’s atmosphere, is causing global warming. In the greenhouse effect, shorter-wavelengths with higher energy are able to transmit through, but not out the atmosphere. On the other hand, long-wavelengths with low energy are able to be transmitted through the atmosphere and out freely. In our case, infrared radiation, which we feel as heat, becomes trapped inside the atmosphere. Our atmosphere heats up when it is exposed to the sun's heat, but eventually levels off at a certain equilibrium temperature, which is the average surface temperature. The equilibrium temperature is the point at which temperatures level out. Earth’s present day atmosphere includes Nitrogen (78%), Oxygen (21%), Argon (0.0093%), Carbon Dioxide (0.00035%), and Water (0.01%). In order to test out this concept of the greenhouse effect, we did an experiment in which we took two bottles, each filled up with dirt. The top parts of each bottle were cut off and we put a thermometer inside each bottle facing outwards. For the experimental bottle, we covered the top of it with plastic wrap and for the control, we left it alone. In the middle of the two bottles, we put a light bulb and at every five minutes, we checked the temperature of each bottle and record...
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.
As we approach the future we are faced with many global problems. Most of these problems arise because we have caused them ourselves. We need to face these problems and find a solution. Global warming, although most often overlooked in importance, is a crucial problem of the future directly related to human activities. Global warming is caused by gases humans release into the atmosphere called anthropogenic gases and by deforestation. Anthropogenic gases include carbon dioxide, methane, chlorofluorocarbons (CFCs), hydrofl...
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”).
Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. This results in an increased evacuation of greenhouse gases. “Short-wave solar radiation sinks into the Earth's atmosphere and warms its surface while long-wave infrared radiation emitted by earth's surface is absorbed, and then re-emitted by trace gases.” (2)
The common definition of global warming 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 and other pollutants (Global warming, Wikipedia). Moreover, the effects of global warming will bring ecological and social changes. Because there is no exact way to predict the effects of global warming, it is almost impossible to say how strong global warming will affect life in the future. Scientists blame the greenhouse gas effect in combination with societies greenhouse gas emissions for the rising temperature. The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions. Since part of this re-radiation is emitted back towards the earth’s surface and the lower atmosphere, it results in an elevation of the average surface temperature above what it would be in the absence of the gases (Intergovernmental Panel on Climate Change). Simply, global...
