  • Essay / How global warming became reality: a retrospective approach

    Humanity is currently facing one of the greatest problems in its history. Indeed, the Earth is warming and the consequences could be devastating for future generations. According to the Common Attitudes towards Anthropogenic Global Warming, “We must all adopt a more primitive way of life and abandon much industry and intensive agriculture, essentially returning to pre-industrial times. The back-to-nature approach will allow the Earth to heal in the short term and allow humans to live in harmony with nature in the long term. (SITE)Say no to plagiarism.

According to the Union of Concerned Scientists, “carbon dioxide contributed more than any other factor to climate change between 1750 and 2011.” The Intergovernmental Panel on Climate Change carried out a global climate assessment in 2013, comparing the actual influence of three environmental changes resulting from human activity. These three changes were the emission of key heat-trapping gases, as well as aerosols, and land use change. They conducted the assessment by measuring the abundance of heat-trapping gases in ice cores, the atmosphere and other climate factors as well as models; and calculated the net increase or decrease in the amount of energy reaching the Earth's surface. Positive values ​​indicated average surface warming and negative numbers indicated average surface cooling. And, in total, carbon dioxide has the highest positive value of all human-influenced climate factors. Some of the other gases mentioned have more powerful heat-trapping capabilities, but are simply much less abundant in the atmosphere. Carbon dioxide passes through the atmosphere through the combustion of fossil fuels such as; coal, natural gas and oil; solid waste, trees and wood products, and certain chemical reactions. This can be sequestered from the atmosphere when it is taken up by plants as part of the biological carbon cycle. Methane is delivered during the production and transportation of coal, natural gas and oil. Emissions also come from livestock such as cows, horses and other farm animals and from the decomposition of organic waste in municipal solid waste landfills. Nitrous oxide is released into the atmosphere during agricultural and industrial activities, as well as during the combustion of fossil fuels and solid waste. Fluorinated gases such as hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and nitrogen trifluoride are man-made greenhouse gases that spread from various industrial processes. These gases are generally found in smaller quantities, but because of their potency they are called high global warming potential gases (high global warming potential gases). This shows how frequently these gases propagate through the atmosphere realizing how frequently and constantly these processes occur. As expected, temperatures in recent years have been among the hottest. The warmest five-year period occurred between 1991 and 1995, with 1995 being the warmest yearhottest ever recorded. Climate change is expected to have wide-ranging effects, including sea level rise, increased prevalence of tropical diseases, habitat loss and extreme weather. Higher temperatures are expected to accelerate the melting of polar ice caps, leading to rising sea levels, which could flood coastal areas and low-lying islands. Scientists predict that as the tropical climate expands north and south, tropical diseases such as malaria, dengue fever and yellow fever will also increase. In Rwanda, malaria rates increased by 337 percent with a 2 degree increase in temperatures. As the climate changes, most species will not be able to survive in their current geographic location. As a result, they will have to move to more suitable areas. However, while plants and animals had 10,000 years to adapt to global warming after the last ice age, they will only have 100 years if humans raise the temperature by a similar amount, around 5 degrees. , over the next century. Scientists believe that global warming will not only lead to higher temperatures, but also extreme climate variations. This is what we have experienced often in recent years, with temperatures of a shocking 70 degrees on Christmas Day 2016. Additionally, hurricanes, blizzards, floods and tornadoes are occurring more frequently. Author Margaret Kriz (2006) states that: "The vast majority of scientists who study Earth's climate agree that the planet is warming and blame greenhouse gases accumulating in the Earth's climate." atmosphere and prevent heat from escaping. Carbon dioxide and methane releases are the two main contributors to climate change. With environmental warming now almost inevitable, methane gases are sure to become an even bigger contributor as the planet warms and more ice melts at the poles. It will take a global effort, like never before, to slow and bring global warming to a much more manageable level. People need to start doing their part. The question is, how are Americans affecting the environment and what can we do about it? Americans use automobiles as a means of transportation every day, and while it may seem harmless, the use of these cars ultimately proves detrimental. According to the Union of Concerned Scientists, "collectively, cars and trucks account for nearly a fifth of all U.S. emissions, emitting about 24 pounds of carbon dioxide and other greenhouse gases for every gallon of essence. » Surprisingly, about five pounds comes from the fuel extraction, production and delivery processes, while an extreme amount totaling over 19 pounds per gallon comes straight out of your car's exhaust. Hybrid cars have been increasingly popular in the United States since 1999, when Honda introduced the first-ever hybrid car. In “No Silver Bullet,” the author describes the utility of these vehicles as “more energy-efficient cars that regulate carbon dioxide emissions.” When there are fewer cars polluting the environment, there is one less problem. According to Kriz's article, more and more research is being done to improve all cars and make all transportation technologies dependent on battery power. With less fuel consumption, the atmosphere has a chance to survive, which..
