Humans Are to Blame for Global Warming Essay

Humans are to blame for global warming, there is no question about it. Humans and human actions are causing a rise in temperature worldwide. We have recorded a steady rise in temperature for the last fifty years. This rise is caused by an estimated 95% of human actions.Humans are to blame for global warming because of deforestation, population growth, and the use of non-environmentally safe products.

Greenhouse gases are accumulating and the dominant cause seems to be the “fossil-fuel-based human economy” (Goodland 604). Greenhouse gases are accumulating in the atmosphere and fast; greenhouse gases include the release of carbon dioxide from burning coal, natural gas, and

Global warming is the steady heating of Earth’s land, oceans, and atmosphere caused primarily by human activity. Climate change is one of the world’s biggest challenges right now, from people actively arguing that it doesn’t exist- to other’s who don’t care enough to do anything about it. There’s evidence showing that climate change is happening and affecting our world now and from what it seems, if action isn’t taken, major consequences will soon arise. Most of the world’s land mass has experienced a 0.2-1.0 degree Celsius average temperature increase since the 1970s, the temperatures of the Artic has increased at almost twice the mean global rate. Climate change is caused by human factors such as greenhouse gases and ozone depletion and because humans are so dependent on fossil fuels in their day to day lives, the issue at hand is only going to get worse.

Global warming has been a major concern and has greatly affected the environment around the world for years. Andrew Revkin stated in a New York Times article entitled “A Closer Look at Climate Panel’s Findings on Global Warming Impacts” that climate change throughout the 21st century will lead to increases in ill-health in many regions, as compared to a baseline without climate change. There have been a number of debates regarding this controversial topic, though most of the scientific community can recognize the existence of global warming. Many often question if this effect on the environment is caused by human activity or natural cycles. About 95 percent of scientific studies prove that global warming is essentially caused by man.

Climate change is a threat that has been in existences for years, but appears to be a greater threat to the world currently. According to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change, there is more than 90 percent certainty 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” (IPCC, 2007).

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.

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.

Every year, almost 7 billion tons of carbon dioxide is released into the atmosphere by human activity. That is the equivalent of 107,700,000 jet airplanes being in the air at once! This harrowing figure is the main cause of global warming, and has been increasing for the last 50 years. Global warming is caused by the increase of greenhouse gasses, carbon dioxide and methane primarily, in the earth's upper atmosphere directly caused by human burning of fossil fuels, industrial, farming, and deforestation activities. Global warming is defined as an increase in the average temperature of the earth's atmosphere (especially a sustained increase that causes climatic

• Carbon dioxide (CO2) is a greenhouse gas that warms the atmosphere. • Since pre-industrial times, atmospheric CO2 concentrations have increased from about 280 parts per million (ppm) to over 380 ppm. Current concentrations of CO2 and other greenhouse gases are unprecedented in at least the last 650,000 years, based on records from gas bubbles trapped in polar ice. • Independent measurements demonstrate that the increased CO2 in the atmosphere comes

In addition, human activities like deforestation may increase the amount of carbon dioxide in the atmosphere. This is because forests help in carbon sequestration, which reduces the amount of carbon dioxide in the air. It follows then that clearing such tress will increase the amount of carbon dioxide since carbon sequestration will not occur (3). The man-made theory of climate change also explains that when these harmful gasses reach the atmosphere, they form a blanket, which traps heat in the atmosphere. This trapping of in the atmosphere is the phenomenon that causes the planet to get warmer, hence the term global warming (Sharma, 4).

In recent years, the controversial subject of global warming has been more predominantly brought to our attention. Is the threat of global warming real? Is it man-made or is this just a natural cycle of earth? Does it really affect earth’s inhabitants? Should action be taken against it? If so, what kind and to what extent? It cannot be only a coincidence that the alarmingly rapid climate change coincides perfectly with the increased amount of pollutants that humans release into the environment. The once stable climate has in recent years begun to skyrocket, thus altering the delicate structure of earthly life. This proves to be hazardous to the future of the planet; some people worry that many of the resources the environment provides that

Carbon dioxide is the greenhouse gas naturally found in the atmosphere. Since the advent of the Industrial Revolution in the 1700s, humans have devised many inventions that burn fossil fuels such as coal, oil, and natural gases, which, along with other human activities such as clearing land for agriculture or urban settlements, help some of these greenhouse gases accumulate in the atmosphere that in turn trap more heat radiation in the atmosphere causing the Earth’s climate to become warmer than it would naturally (Mastrandrea). This unnatural phenomenon is termed global warming by scientists and they blame it for an increase in the Earth’s surface temperature of about 0.6°C (about 1°F) over the last 100 years (Mastrandrea).

"Two thousand scientists, in a hundred countries, engaged in the most elaborate, well organized scientific collaboration in the history of humankind, have produced long-since a consensus that we will face a string of terrible catastrophes unless we act to prepare ourselves and deal with the underlying causes of global warming."

To begin with, the environment we choose to place ourselves in has the ability to impact our wellness within an instance. With that being said, there’s a possibility our wellness is likely to be threatened. For those apart of organizations concerned about the wellness of others, it’s their responsibility to inform the community about how to prepare themselves for environmental changes. What has the possibility to occur within an environment varies. Everyone adapts to alterations differently, but is human activity responsible for global warming negatively affecting human health?

Global warming is the constant increase of temperature in the earth’s atmosphere that is caused by the increase of carbon dioxide, chlorofluorocarbons, greenhouse gases and many other pollutants. Chlorofluorocarbons are any type of compounds of carbon, hydrogen, chlorine, and fluorine which are harmful to the ozone layer. Global warming can affect many things, one example is the rising of temperature which can result in different types of disasters like storms, heat waves, floods, and droughts. Global warming also causes Higher death rates, Dirtier air, Higher wildlife extinction rates, the increase of Acidic Oceans, and Higher seas levels. In this essay, I will provide information that will show how harmful global warming can be to not only the earth but to humans and animals, and what we can do to prevent it from increasing.
