The Complications Of Global Warming

Improved Essays
Stewart Negron At this point in time, the world has reached a point of no return climatically and the impacts of “Global Warming” are inevitable. Given current atmospheric research, climate change is proven to be a true, unnatural feedback caused by human activity. Due to the medias selective exposure of climate change information, specifically of the skeptic views of the topic, society has not grasped global warming as a current and vital issue. Additionally, the refusal to join climate protection programs by the United States government gave civilians no incentive to act on the issue. At this point, the public needs to make climate change a priority over capita and economics before Mother Nature’s fury catches up. The debate is over and …show more content…
The primary cause of climate change is the increased emission of greenhouse gasses by human processes. The most significant greenhouse gasses include carbon dioxide, methane, water vapor and nitrous oxide. In order to understand the effect greenhouse gasses have on the earth, one must comprehend how energy enters and exits the atmosphere. The sun constantly emits short wave radiation. This radiation can be dangerous to human health in large quantities, causing sunburn and skin cancers. Ozone (O3), another greenhouse gas, protects life on the surface by absorbing most of the damaging ultraviolet radiation from the sun. In order to maintain a radiative equilibrium, an equal amount of long wave radiation is released back into space. However, due to greenhouse gasses, not all of the terrestrial radiation makes it directly back to space. Greenhouse gasses are unique in that they are transparent to solar radiation, but absorb terrestrial radiation. This in return heats up the troposphere, thus the term “Global Warming” is …show more content…
Some claim climate change is due to impacts of volcanic emissions, solar forcing, and changes in orbital parameters. Volcanic activity releases carbon dioxide, sulfur dioxide, and carbon ash into the atmosphere. However, volcanic emissions are more likely to cause atmospheric cooling rather than warming since sulfur dioxide acts as an aerosol reflecting short wave radiation, reducing the amount that reaches the surface. Ash is typically insignificant in a climatic perspective since water in the atmosphere quickly filters out the carbon, depositing it back to the surface. Additionally, volcanic activity is responsible for an insignificant amount of carbon dioxide in the atmosphere when compared to the amount of anthropogenic emissions. According to the IPCC AR5 (2013), since 1750, volcanic carbon dioxide emissions have been at least 100 times smaller than anthropogenic emissions (Myhre et al. ch. 8, p. 62). Solar forcing refers to changes in the amount of radiation that reaches the earth’s surface. Sunspot cycles cause changes in solar irradiance. These occur over periods of eleven years, yet cause minimal changes in the suns luminosity and even smaller changes in the earth’s radiative equilibrium temperature. Such a small change in temperatures over such a long time period cannot explain

    One of the major problems facing our world today is global warming. “Global Warming is the increase of Earth 's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth” (“ What is Global…”, n.d.). There is a major difference between global warming and greenhouse gases. The greenhouse effect is a natural process in earth’s atmosphere that maintains the average surface temperature. It is caused by certain gases such as water vapor, ozone (O3), carbon dioxide (CO2), and methane (CH4), and traces of chloro-fluoro-carbons (CFC 's).…

    Causes and Effects of Global Warming Aside from war, poverty, and crime, one of the major world issues is global warming. Global warming is a phenomenon caused by the hole in the ozone layer. This hole allows ultraviolet, also known as UV, rays to cover the Earth like a blanket since the purpose of the ozone layer is to block these rays. The burning of fossil fuels releases carbon dioxide into the air that wraps the UV rays around the Earth which causes the warming of the Earth. In understanding what global warming is and what causes it, we can better understand how to prevent global warming and preserve our Earth.…

    The mount Pinatubo eruption of 1991 had a global cooling effect, this effect was noted by a drop in the rate of warming that was going on in the early 90s as a result of global warming from CO2 emissions. Although volcanoes are a natural mechanism by which aerosols enter the atmosphere, anthropogenic aerosol release is also a possibility. Whenever you kick dust up into the air, you are putting aerosols into the atmosphere, the only difference between a volcano and anthropogenic dust is that the latter doesn 't usually reach the stratosphere, so it stay down closer to the surface, giving it a lower residence…

    At specific wavelengths of this infrared radiation, the carbon dioxide molecules absorb the energy instead of allowing it to be released back into space. This means that heat that should have left our planet ends up staying. This result in what we now know as climate change. CU: Okay so? The Earth gets a little warmer?…

    If there was life on Venus, it would definitely not be humans. Life would have to be something heavier, more durable, and used to living under an extremely hot pressure. Scientists also seem to believe that life may have existed on Venus more than a million years ago. There has not been any sign of water on Venus for about 600 million years, and they believe this is caused by the runaway greenhouse effect that makes the planet so hot and humid. Before the runaway greenhouse effect took over Venus, there was a possibility of oceans and cloud filled with water vapor.…

    If the carbon dioxide is kept too much in the atmosphere, it will be the increase of greenhouse gases, and the earth will become warmer. Jarred Skype (n.d), an environmental scientist, pointed out in his article, “The primary cause of environmental degradation is human disturbance. The degree of the environmental impact varies with the cause, the habitat, and the plants and animals that inhabit it”. Obviously, environmental degradation happens when people exploit and overuse the components of…

    Dangers Of Solar Winds

    The sun is the star we are orbiting, which gives us heat and more stuff. Of course, it is also potentially dangerous, it can cause skin cancer, solar winds, too much heat, and it will obviously end up destroying the earth in a few billion years. I am especially studying the solar winds, this is because I think that solar winds are more interesting than the others because they look as if they were more fun and had more things to talk about. The problem with solar winds is that they come to the earth from the sun and they are highly charged and can take down electric systems and can maybe even kill humans. Of course, we have a magnetosphere which protects us from this danger, but not completely, there are still dangers like when the solar winds…

    Our planet would be too cold to support life if not for a natural process called the greenhouse effect. The sun sends solar radiation toward the Earth’s surface. Of which, 70% is initially absorbed by the Earth’s surface. However, as the earth warms, some of this absorbed energy is reflected back toward space as infrared radiation. This infrared radiation would be lost into space except for the fact that there exist greenhouse gases such as carbon dioxide and water vapor in the atmosphere that absorb the infrared radiation and sends some of it back to Earth’s surface, keeping Earth at a temperature that can support life.…

    Majority of scientists agree that the current global warming is due to human expansion of the “greenhouse gas effect”, that is, when the greenhouse gases absorb IR radiation and prevent it from radiating toward outer space which results in gradual heating of the Earth’s atmosphere and surface. Greenhouse gases that contribute to the global warming include water vapor, carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons. Human activities are changing…

    The reason why global warming occurs is, because of the rotation of the sun that continually changes the density of the sunlight. Another cause of global warming is greenhouse gases. Greenhouse gases are sulfur dioxide and carbon monoxide it trap the solar heat rays and prevent it from escaping from the surface of the earth. And according to (Lallanila, 2017) these greenhouse gases will make the earth's temperature increase. One more cause is volcanic eruption; for sure it will cause global warming.…
