What Are The Causes Of Global Warming?

Introduction
The Earth’s climate is experiencing rapid changes, which can be attributed to human activities. Certain gasses, such as Carbon Dioxide (CO2), act like a blanket and trap heat in the atmosphere. These gasses are released into the atmosphere everyday through the burning of fossil fuels. This phenomenon, called the greenhouse effect, is naturally occurring, and is necessary for life on Earth. However, the extreme accumulation of these gasses results in dangerous effects to Earth’s ecosystems and human health. The more greenhouse gasses get burned, the more carbon dioxide there will be in the atmosphere to trap more heat. But how do scientists know the leading cause of global warming is from humans?
Founded in 1988, the Intergovernmental Panel on Climate Change (IPCC) is a United Nations body that researches climate change science. The IPCC’s fourth assessment report states that they are “greater than a 90 percent certain that emissions of heat-trapping gases from human activities have caused ‘most of the observed increase in globally averaged temperatures since the mid-20th century’” (Para. 3). According to the IPCC, humans leave behind “fingerprints” on the carbon. In order to generate electricity or power cars, humans must burn coal, oil, and gas. The carbon molecule released in these processes weighs less than a

This is done with solar photovoltaic systems, which directly convert solar energy into electricity. The most established PV technologies are crystalline silicon based systems. They yield high output of electricity but require direct sunlight. Wind energy is converted to electricity through turbines. Turbines capture wind and spin. The spinning blades are connected to an electric generator that produces electricity. Wind energy is completely emission free. Increasing the use of solar and wind energy can decrease the use of fossil fuels, leading to less greenhouse gas

    What makes fossil fuels a big cause of global warming is the burning of fossil fuels. When people burn fossil fuels it sends out large amounts of Carbon Dioxide into the air. Carbon dioxide is bad for the Ozone layer, it causes sun rays to heat up the earth even more. Another leading cause of global warming is those devices that get us around town, vehicles. Vehicles are a big leading cause of global warming.…

    (Grounds) The daily ritual of turning on electricity for many people; releases many greenhouse gases based on the form of electricity used. While small quantities of carbon dioxide do exist naturally in the atmosphere, the generation of electricity has greatly increased the presence of greenhouse gases in the planet’s atmosphere. The overwhelming majority of scientist believe that this contributes to an unnatural degree of global warming that has the potential to affect the global climate, destroy animal populations and change local ecosystems. (Backing)(Thompson 2) (Warrant) Electricity increases the amount of greenhouse gases leading to the increase in global climate; switching electricity systems to solar panels should decrease the amount of greenhouse gases which then would allow for the temperature increase to slow…

    What are the problems? One huge issue is global warming, which is caused by chemicals building up in our atmosphere that hold heat on earth, rather than going further up into the atmosphere. One huge chemical creating this issue is CO2. These gases are being emitted by humans at an alarming rate.…

    As reported by Ener-Data, from 2000-2014, the United States alone, consumed 2,224 Mtoe (million tons of energy) (Ener-Data; World Energy Statistics). This number is quickly climbing. The more the population in the world increases, the more energy is consumed. I believe that if everyone bought and used the Tesla Powerwall, we could cut down on costs and pollution. In class we talked about major energy sources and their advantages and disadvantages.…

    Greenhouse gases are the main cause of global warming. Human beings have raised carbon dioxide in the atmosphere with their activities, such as deforestation, and burning fossil fuels. The other major causes of global warming is population growth, pollution, and industrialization. These changes are resulting rise in sea level, melting glaciers, damage of the ozone layer, unseasonable rains, and also increasing many other environmental problems. Impacts of global warming can be seen in countries like Australia and New Zealand.…

    “This system can distribute heat more effectively throughout a dwelling because of its pumps and fans,” (Mongillo 42). The Active Solar Heating System requires three difficult solar subsystem steps that explain the process of how to convert energy from the sun in the simplest form (Mongillo 41). The Active and Passive Solar Heating systems have many tools that are involved in the long process, but a solar photovoltaic cell helps to speed up the process (Mongillo 41). Another type of energy device is solar photovoltaic cell, also known as PV, converts sunlight directly into electricity. In 1954, the photovoltaic cell was founded, scientist found that silicon produced an electric charge while it was in direct sunlight (Mongillo 42).…

    Are humans solely to blame for global warming, or is it bound to happen by natural causes? Scientific evidence and much research are giving that answer. Human behaviors are the source of the rapid increase in global warming. Global warming can be described in many ways. 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).…

    Carbon dioxide is the most important, as it accounts for eighty percent of total greenhouse gas emissions. Agreed on by scientists, the climate’s warming is essentially due to the abundant amount of carbon put into the atmosphere by humans (citation). This gas results from burning fossil fuels and brushland for agriculture, wood fires used for cooking, the cutting/burning of forests, and producing cement (citation). Almost one-third of the carbon pollution in the United States of America comes from motor vehicles, as well. According to the Environmental Defense Fund 2013, the current carbon dioxide levels are higher by forty-percent than the highest levels over than the past 80,000 years.…

    Today, we are facing the environmental crisis of global warming. A major factor that is contributing to this is the use and burning of fossil fuels such as coal, natural gas, and oil. Through the process of coal burning, Carbon Dioxide is formed as a result, which is one of the major causes of the Greenhouse effect. With the Greenhouse effect, the Earth’s average temperature rises, causing ice caps to melt, which is an effect of global warming. To put a stop to this, our population needs to change our current energy sources to renewable resources, such as solar energy.…

    Ways to Prevent Global Warming Global Warming is a term used to describe an increase in average temperature of Earth’s surface, Atmosphere and oceans. Global warming is caused by greenhouse gases such as carbon dioxide emits into the atmosphere, also caused by burning of fossil fuel and deforestation. Average temperature around the world has increased by 0.75 Celsius. in past 100 years. David G Victor said in his book that global temperature around the world has been increasing rapidly.…
