In late years, however, excess emissions of carbon dioxide and other greenhouse gases from human activities processes (mostly burning fossil fuels) have started to warm Earth's climate at a problematic rate. This has caused the global average temperature to raise, and may potentially harm many life form on earth in near future. They are generating major greenhouse gases (GHGs) which enhance greenhouse effect. This raises the global average temperature leading to climate change, and may potentially harm many life form on earth in near

Global Warming has been a big issue that has effects on the environment, people, and the world, and if not stopped now, the results could be catastrophic. The main cause of climate change is likely to be the result of too much carbon dioxide (CO2) in the atmosphere. CO2 creates a blanket which traps heat. Burning fossil fuels for energy, such as coal, oil, and natural gas release CO2 which impacts the atmosphere heavily. Waste management and agricultural practices also produce gases that contribute to climate change, such as methane. There are many contributing factors to climate change.

When Carbon dioxide is released into the atmosphere over time the carbon will add up resulting in the average temperature of Earth’s air and ocean. The temperature change takes over hundreds of years to change so the average temperature we see right now could most likely still rice if all carbon dioxide emission are eliminated. Humans contribute to global warming by increasing the greenhouse effect. The greenhouse effect occurs when greenhouse gases, carbon dioxide, methane, nitrogen oxide, and fluorinated gases, collect in the earths atmosphere. Sun light passes through the atmosphere to the earth surface to allow the earth to heat up. The atmosphere traps the heat on earth to develop the earths temperature. The greenhouse effect is ruining this because the greenhouse gases trap to much heat on the earth causing overtime a higher average temperature. Carbon dioxide accounts for 82% of all United States greenhouse gas emissions from human activities. Currently the United States is ranked second in the top carbon dioxide emitters in the world.

Today, atmospheric CO2 concentration has nearly increased by 25 percent, and the global temperature has risen by nearly 1.25 degrees as reported in 2014 (U.S. Global Change Research Program, 2014), as part of a continuous rise since the 1800s. This may seem small but are having a huge effect on the Earth and causing global warming, and in turn, climate change. These changes are predominantly blamed on humans, through actions such as fossil fuel consumption, deforestation, and increased agricultural production and

Human activities are the leading contributing factors to climate change contributing to global warming. Whether it’s driving cars or heating our homes with natural gas, we are releasing carbon dioxide into the atmosphere. According to an article written by Darryl Fears, “the planet is warming at an accelerated pace without any doubt, that humans are causing it with 95 percent certainty and that the past three decades have been the hottest since 1850.” The majority of human causes of global warming can be contributed to the increase of greenhouse gases, such as carbon dioxide, methane and nitrous oxide, into the atmosphere. Of the greenhouse gases, carbon dioxide is said to be the most considerable cause of global warming, and most carbon dioxide emissions are the result of burning fossil fuels.

The United States Environmental Association (EPA) has listed natural changes in greenhouse gas (GHG) concentrations, volcanic eruptions and solar energy as some of the natural causes of climate changes on earth. However, the recent climate changes cannot be explained by natural causes alone. Research indicates that natural causes are very unlikely to explain most observed warming, especially warming since the mid-20th century. Rather, human activities can very likely explain most of that warming. These human activities are the causes of anthropogenic climate changes. The article also adds “Since the Industrial Revolution began around 1750; human activities have contributed substantially to climate change by the addition of CO2 and other heat-trapping gases to the atmosphere. These greenhouse gas emissions have increased the greenhouse effect has caused Earth’s surface temperature to rise. This is the primary reason which is affecting the amount and rate of climate change is greenhouse gas emissions from the burning of fossil fuels.” Other activities that initiate climate changes are caused by the gas emissions from fossil fuels used to heat homes, petroleum based fuels like gasoline and diesel used for transportation and electricity production which comes from burning fossil fuels.

There are many factors and catalysts making small inclinations and changes within global temperature, but mankind has been the biggest, causing detrimental harm to the world in global warming. Throughout history there are natural causes that factor in small and short term climate change, such as the occasional volcano erupting, or an excess of greenhouse gases in the air, which are gases that help absorb radiation, which as a result keeps heat within the atmosphere, having a warmer net temperature. Annually there are many fluctuations that cause minor altercations within but humanity doesn't help either. During post 1850s since the industrial revolution, the significant uses of coals, oils, and fossil fuels, have caused an exponentially increasing amount of carbon dioxide to be released

A scientist that reports for National Geographic Magazine stated, “Since 1990, yearly emissions have gone up by about six billion metric tons of “carbon dioxide equivalent” worldwide, more than a 20 percent increase”(“Causes of Global Warming”) Humans are the cause of global warming. Overpopulation of the human race has resulted in a multitude of carbon dioxide gas getting trapped in the atmosphere, warming the earth as if it was a greenhouse. Carbon dioxide (Co2) is a “waste” gas of human beings. One human approximately exhales two and one third pounds of carbon dioxide gas a day(Palmer) Consequently, the gas is warming the earth from the core up. Humans are the cause of global warming.

Human activities such as deforestation, burning fossil fuels and transportation emissions have caused warmer climate changes. These factors all are increasing the “Greenhouse Effect” which is when the carbon gets released into the atmosphere, furthermore this causes those gases to be trapped inside the earth’s atmosphere causing multiple of the effects. Global warming is harmful to the environment because there has been an increase in global temperature, incline in natural disasters, and extinction of animals throughout the world. These factors are only a small percentage of what global warming is doing. Without human intervention global warming would not be a problem that this planet would face, it's our priority to save this planet for ourselves and for future generation.

During the past century, human activities have released large amounts of carbon dioxide and other greenhouse gases into the atmosphere. Most of the gases come from burning fossil fuels to produce energy. Greenhouse gases are like a blanket around the Earth, trapping energy in the atmosphere and causing it to warm. This is called the greenhouse effect and it is natural and necessary to support life on earth. However, while greenhouse gases buildup, the climate changes and result in dangerous effects to human health and ecosystems. People have adapted to the stable climate we have enjoyed since the last ice age which ended several thousand years ago. A warmer climate can bring changes that can affect our water supplies, agriculture, power and transportation systems, the natural environment, and even our own health and safety. There are some climate changes that are unavoidable and nothing can be

Greenhouse gases ,such as carbon dioxide, is absorb and emits heat into the earths atmosphere, keeping the Earth warm enough to support life. However, human activities, such as burning fossil fuels, are adding large amounts of greenhouse gases to the atmosphere. Earth must get rid of energy at the same rate it receives energy. More greenhouse gases means that more heat is being held in the atmosphere, which makes the temperatures higher. All the greenhouse gases people have added to the

During the last century, human activities in agriculture, industry and technology have brought about a change in the chemical composition of the atmosphere. This change so far has not had a noticeable or discernible effect on world climate, but if these same activities continue, global climate change will become irreversible. The major contributing factor is the increase in the amount of carbon dioxide and other gasses in the atmosphere. These gasses are being cited as the cause for a "greenhouse effect" where they trap the heat of the sun and cause global climate change, specifically a warming trend

Climate change is caused by carbon emissions being trapped in earth’s atmosphere. The pollution that is trapped in our atmosphere then heats up changing earth’s climate patterns. The act of burning fossil fuels for energy has the biggest contribution to climate change. Scientists are confident that global temperatures will continue to rise for many years to come, all because of human activities. The intergovernmental panel on climate change also known as the IPCC came to a conclusion that it is 90% probable that the globe is warming due to human activities over the past 250 years. The IPCC, has a large depth of knowledge with having over one thousand three hundred scientists. The IPPC scientists predict a temperature rise of 2.5 to 10 degrees Fahrenheit over the next century.

Carbon dioxide is a greenhouse gas that is found naturally in the Earth’s atmosphere. All the extra carbon dioxide, produced by burning fossil fuels, is making the greenhouse gases around the Earth too effective. In other words less energy escapes back into space. Instead, the trapped energy in our atmosphere heats up the Earth’s climate, causing climate change. There are also other things humans are doing that are increasing the amount of carbon dioxide in the Earth’s atmosphere. Plants and treed absorb carbon dioxide as they use it to make food through photosynthesis. This is another cause of an increase in carbon dioxide because of the amount of deforestation that is taking place. So, instead of carbon dioxide being locked away in plants and trees, it is up in the atmosphere. An example of this is

The earth’s climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the buildup of greenhouse gases –– primarily carbon dioxide, methane, and nitrous oxide. The heat-trapping property of these gases is undisputed. Although uncertainty exists about exactly how earth’’s climate responds to these gases, global temperatures are rising.
