Natural Vs Anthropogenic Climate Change

Superior Essays
Global warming is the process in which sunlight that is being redirected back into space gets trapped inside of the Earth’s atmosphere due to the abundance of carbon dioxide and other greenhouse gases. The more heat that is trapped and absorbed by such gases causes the overall temperature of Earth to rise. It is natural and anthropogenic – human induced – climate changes that are attributed to increased gases in the greenhouse effect, though anthropogenic changes play a larger role in global warming. Despite the fact that humans have been a major role in speeding up global warming, there are mitigation methods that would slow the rate of global warming, such as carbon taxing and clean coal technology. Thus, if countries are held more accountable …show more content…
As Holli Riebeek states, “The global average surface temperature rose 0.6 to 0.9 degrees Celsius (1.1 to 1.6° F) between 1906 and 2005, and the rate of temperature increase has nearly doubled in the last fifty years” (2010). If global warming was not actually taking place, such sudden jumps in surface temperature over the past fifty years wouldn’t have occurred. Instead, there would most likely have only been subtle increases as natural climate change would not have affected the earth in such ways. Riebeek goes on to explain that, “As the Earth moved out of ice ages over the past million years, the global temperature rose a total of 4 to 7 degrees Celsius over about 5,000 years. In the past century alone, the temperature has climbed 0.7 degrees Celsius, roughly ten times faster than the average rate of ice-age-recovery warming” (2010). This further shows that global warming is occurring due to the fact that surface temperatures are escalating much quicker over a much shorter period of time than in the past. Another point made by Riebeek is that natural climate changes are still occurring today as in the past, but their impact on earth’s atmosphere is either too insignificant or too prolonged to affect surface temperatures in such a way that has been …show more content…
These implementations are known as mitigation strategies. One mitigation strategy is known as clean coal technology. Coal is one of the most abundant fossil fuels used in the world; however it produces very large quantities of carbon dioxide into the air. Thus, if there was a way to make coal ‘clean’, it would be an efficient mitigation strategy. According to the World Nuclear Association, “The most promising 'clean coal ' technology involves using the coal to make hydrogen from water, then burying the resultant carbon dioxide by-product and burning the hydrogen,” (2015). However, they go on to say that, “The greatest challenge is bringing the cost of this down sufficiently for ‘clean coal’ to compete with nuclear power on the basis of near-zero emissions for base-load power. There is typically at least a 20% energy penalty involved in 'clean coal ' processes,” (2015). While clean coal technology sounds like a good mitigation strategy due to lower carbon dioxide emissions, the cost and lessened energy output would make it much less effective than using regular

    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…

    Some of these positive effects are controlling climate change and health issues. A negative effect is public acceptance of the CCS. As CO2 is emitted into the atmosphere by burning natural resources, it builds up over time because in cannot escape the atmosphere. Over time there is so much carbon dioxide build up in the atmosphere that the earth starts to warm up. The earths’ temperature has risen one degree Celsius since the pre-industrial age.…

    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…

    Earth Observatory: Where every day is Earth Day explains, “…aerosols now use hydrocarbons and compressed gases, such as nitrous oxide, as propellants. The chemicals are greenhouse gases that contribute to global warming… containing organic compounds that release ozone into the lower atmosphere and add to smog.” In other words, solar radiation causes aerosols to warm the air. Although they are small particles, together they have a vast impact on the earth. Since aerosols act as propellants, it means that aerosols have the ability to absorb sunlight and heat from the earth. All in all, the negatives of global warming outweigh the positives.…

    By definition, global warming is the unusually rapid increase in Earths average surface temperature over the past century primarily due to the greenhouse gasses released by people burning fossil fuels (3). In other words, carbon dioxide and other global warming pollutants are collection in the atmosphere like a thickening blanket, trapping the suns heat and causing the planet to heat up (7). All in all, global warming is one of the world’s most pressing problems (9). It cannot just be ignored. Human…

    Global Warming Global Warming is an increase in the earth 's atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting especially from pollution. The Earth 's temperature is rising every year, between 1906 and 2005 the temperature rose 1.1 degrees to 1.6 degrees and has doubled in the last 50 years. The greenhouse gases are needed for human life on this earth, global warming is slowly taking out these gases and hurting the planet and the the human and wildlife. Since 1975 scientists and environmentalists have been studying global warming and the effects climate change has had on earth. Today we believe that the damage done to the ozone affects our wildlife and much more and we…

    Every fossil fuel, coal, oil and gas is composed of carbon and hydrogen atoms, oxidizing these atoms releases their heat energy into the atmosphere. Natural gases have the highest hydrogen per carbon index, meaning it is a very low carbon intensive fuel. Coal is just the opposite, this means that burning these fuels releases CO2 into the air, trapping heat from the surface therefor warming the planet. A carbon dioxide tax means that users of fossil fuels will pay for the environmental damage their fuel use causes from releasing carbon dioxide into the atmosphere. This motivates a transition to use cleaner energy and the further production of renewable energy.…

    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).…

    Natural causes of climate change include variations in the sun’s energy reaching earth and changes in the reflectivity of the Earth’s atmosphere and surface. Also, changes in the greenhouse gas effect is a cause of climate change because it affects the amount of heat retained by Earth’s atmosphere. Volcanic eruptions discharge carbon dioxide and they emit volcanic ash or dust and sulfur dioxide into the atmosphere contributing to the causes of climate change. Also, El Niño is an oscillation of the ocean and atmosphere system in the tropical area of the Pacific Ocean that affects global climate change also. Another natural cause is orbital changes in the earth, changes in the earth’s orbit and tilt cause the climate fluctuations that…
