Causes And Effects Of Global Warming

Improved Essays
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 ozone layer is the layer in the atmosphere that protects from the sun’s harmful UV or ultraviolet rays. Over …show more content…
As previously stated the main purpose of the ozone layer is to filter out UV rays from the sun that are harmful to life. Without complete protection from these UV rays, the rays are allowed to move deeper into the Earth’s atmosphere. As the rays move deeper they are wrapped around the Earth like a blanket by the chemical carbon dioxide. Carbon dioxide is put into the air by the burning of fossil fuels such as coal and natural gas. According to ucsusa.org, “Global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars. Carbon dioxide spreads around the planet like a blanket, and is one of the main gases responsible for the absorption of infrared radiation (felt as heat), which comprises the bulk of solar energy.” This quote is evidence of how the hole in the ozone layer allows UV rays to be wrapped around the Earth causing the warming of the …show more content…
These include the melting of the ice caps and sudden climate change. National Geographic states: “The planet is warming, from North Pole to South Pole. Since 1906, the global average surface temperature has increased between 1.1 and 1.6 degrees Fahrenheit (0.6 to 0.9 degrees Celsius)–even more in sensitive polar regions. And the effects of rising temperatures aren’t waiting for some far-flung future–signs of the effects of global warming are appearing right now. The heat is melting glaciers and sea ice, shifting precipitation patterns, and setting animals on the move.” This evidence states that global warming is causing relatively rapid climate change, the melting of ice caps, and the migration animals out of their natural habitats. National Geographic goes deeper into the melting of ice caps by stating, “Ice is melting worldwide, especially at the Earth’s poles. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice.” Also, native species are moving away from Antarctica while invasive species are growing in numbers. According to National Geographic, “Bill Fraser has tracked the decline of the Adélie penguins on Antarctica, where their numbers have fallen from 32,000 breeding pairs to 11,000 in 30 years...Some butterflies, foxes, and alpine plants have moved farther north or to higher, cooler areas...Some invasive species are thriving. For example, spruce bark

    Global warming is produced by the trapping of the rays in earth’s atmosphere by the rising of carbon dioxide, which causes the excessive heating. The carbon dioxide absorbs most of the infrared rays and does not allow them to pass to the earth which causes them to not escape and remain…

    Does human activity affect climate change causing global warming? To understand global warming better, we need to better understand greenhouse effect and greenhouse gases. So, what is the greenhouse effect? Greenhouse Effect is the trapping of the sun’s heat in a planet’s lower atmosphere, due to the transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the surface. Some greenhouse gases that cause global warming are water vapor, ozone, carbon dioxide, and methane.…

    Global warming is the increasing of the earth’s surface temperature. Green house gases as mentioned earlier are those that contribute to the greenhouse affect. An overall warming of the earth as atmospheric gases trap electromagnetic radiation that should have been radiated back into space. These gases are thought to affect climate change even though they make up such a small amount of the atmosphere they play a large role. In summary climate change is referring to changes brought about by different factors one of these factors is the greenhouse affect, which cause shifts in global warming, and in term changes the overall…

    Fossil fuels are used to power cars and machinery among many other things humans use (Rowlands, 1991). The world primarily uses fossil fuels for power, and the hole in the ozone layer is attributed to fossil fuel use (Gonzalez & Lucky, 2013). The hole in the ozone layer could also be caused by Antarctica constantly being hit by the sun’s rays (Boehm, 2010). Since there is a hole in the ozone layer, the radiation and heat from which the ozone layer would have protected Earth from are let in and cause the Earth to warm. The holes in our ozone layer are unprotected spots on Earth which expose us to the foreign substances of space.…

    In the same fashion activities like burning of coal, exhaust fumes from cars, and tree burning produce extra amounts of gas contributing to greenhouse effect or global warming. Global warming as a result is caused from greenhouse effect. Furthermore, the burning of fossil fuels is really important to this issue. Fossil fuels are any combustible material, as oil, coal, or natural gas, derived from the remains of former life. Fossil fuels contain carbon and when burnt the carbon combines with oxygen in the atmosphere forming carbon dioxide.…

    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.…

    Darius Brown, Professor Yenko, Comp Reading, Spring 2015 The greenhouse effect and global warming are both issues that are talked about by scientists all across the globe. The greenhouse effect is "the trapping of heat in the earth 's atmosphere." (Shuster, 583) Energy from the sun warms the earth. That heat then dstributes back to the atmosphere where it is absorbed by greenhouse gases. (Shuster, 583) One of the most common greenhouse gases is carbon dioxide.…

    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.…

    These crafts emit gases and particles high in the atmosphere by doing so; they damage the ozone layer. Aircraft engines produce emissions that are similar to other emissions produced by fossil fuel combustion. When fuel is burned, the carbon in the fuel is released and bonds with oxygen in the air to form carbon dioxide. Scientific studies have shown that high-altitude emissions are harmful to the climate and the Earth. They are harmful to climate because they trigger chemical reactions and atmosphere effects that have a net warming effect.…

    These gasses are getting trapped in the earths atmosphere, causing the temperature to rise. The effects of global warming are all around us and are becoming more prominent. This climate change is a serious threat that needs to be addressed. The sea levels are rising, food shortages are popping up, the global temperature is rising, and much more. As the base temperature of the Earth starts to rise, the polar ice caps are melting.…
