Global Warming, Not Caused by Humans

Global Warming has silently crept into our society today because of big business, lack of technology, and greed. And now with a new generation of citizens who understand what we have been doing to our earth have to stand up and do what is right. Global Warming refers to the increase in the earth’s average temperature induced by human activity. Most discussions on Global Warming today show similarities between an increase in global temperature and the increase in carbon dioxide, nitrous oxide, methane, and chlorofluorocarbons in the atmosphere. Human activity increases the amount of these gases in the atmosphere and, as a result of the greenhouse effect, increases

The Earth’s temperature has been rising over the years. Sail Bhattacharya a professor & head of a medical college claims that over the last 8000 years, Earth’s surface temperature raised by 1 degree Celsius only (1). He also said, at the present rate of global temperature would rise by 2.5 degrees Celsius by 2050” (1). It’s a fact that the earth has gotten warmer over the years. At this moment the temperature hasn't raised much, only 1 degree Celsius. It may seem like it’s not a big deal, but it actually is, because the rising temperature rate is increasing as time passes according to Sail Bhattacharya (1). The temperature rising might not cause much harm now, but can badly affect us or whoever is living on Earth in the future.

The major contributors to climate change so far had been the Industrial Revolution and the invention and wide-spread use of the gasoline powered automobile. The world had now become industrialized and new technologies were constantly being invented. The next big event to come from this happened soon after 1945. After the end of World War II in 1945 the world’s economy started to recover. This sent industrial production into overdrive. The automobile industry quadrupled and major corporations became bigger than ever before (Jeffries). The United States had begun to feel the effects of industrialization in the 18th century, but at the end of World War II the economy was beginning to pick up sending the United States into another period of industrialization. The burning of all this coal and oil put pollution into the atmosphere, partially blocking the sun’s rays. This effect caused the years 1940-1970 to get cooler, leading some to speculate that the world was heading toward a new ice age (Jeffries). But in the 1970’s the earth started getting warmer again, and the phrase “global warming” was now used in some research papers (Jeffries).

According to Penn State University researcher Michael Mann “ the average global temperature was relatively unchanging in pre-industrial times but sky-rocketed since 1900, and will increase by several degrees more over the next 100 years. There is no convincing empirical evidence that past climate was unchanging, nor that 20th century changes in average global temperature were unusual or unnatural”.

It was notable because of the significant increase number of population aligned with the time of those agriculture activities (Dearing, 2006). Climate can also be in relation with global warming, mainly regarding the global temperature. According to Dawson and Spannagle (2009), both natural and anthropogenic (huma-caused) factors can contribute to global warming, but the overwhelming scientific consensus is that the increase in global temperatures over the past century is primarily due to increased concentrations of greenhouse gases in atmosphere. The concentration of these gases, when converted to their carbon dioxide equivalent, had been relatively stable for 10,000 years but has increased by more than 40% since 1750. They are now higher than they have been for at least 650,000 years, and probably for several million years. Anthropogenic greenhouse gas emissions, principally from the burning of fossil fuels, deforestation, and agriculture, have been the main contributor to the rise of

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.

Global warming is a huge issue that we have to deal with. The world is getting warmer. Whether the cause is human activity or natural variability most of evidence says it is because of humans. Thermometer readings all around the world have risen steadily since the beginning of the Industrial Revolution in Great Britain (“earthobservatory”).

Something which has never before been seen is happening now. The Earth 's atmosphere is warming more rapidly in the past 100 years than ever before. According to physicist Jennifer Burney (2013:54), the current warming trend being seen today has everything to do with the social and economic advances from the 19th century Industrial Revolution. During this time, fossil fuel use accelerated the changes we see today in agriculture, manufacturing, and power. For example, fossil fuels such as oil, coal and natural gas supply most of the energy needed to fuel the cars we drive, and generate electricity for industries and households. Unfortunately, the burning of these fossil fuels puts too much carbon dioxide into the air. This in turn, increases the number of greenhouse gases in the atmosphere causing our climate to become hotter. With that being said, there is a scientific consensus that climate change is occurring, and that human activities are the primary driver. Warming of the climate system is undisputable, and according to Dr. Michael Mann (2009:14), who holds joint positions in the Departments of Meteorology and Geosciences at Penn State, states that scientists are more than 90% positive that global warming is primarily caused by increasing concentrations of greenhouse gases produced by human activities such as the burning of fossil fuels and deforestation. After rapid industrialization, the two primary causes of man-made global warming are the burning of fossil fuels and

The issue of anthropogenic climate change, more commonly identified as global warming, has become hotly debated in the media and political arenas. Critics argue that global warming does not exist and that it is merely a fiction created by the science community. Such critics argue further that what scientists are describing as global warming is either a transitory condition or part a cyclical situation that has occurred throughout history. As a result of this critical opposition the question becomes global warming is a problem that needs immediate and/or long term attention? What the critics of global warming are failing to consider is the mountains of evidence provide by the scientific community that supports the fact that global warming is a reality and that it is human behavior that has caused this condition and it is only human behavior that can remedy the situation. Within the scientific community there is little disagreement that global warming is a serious problem.

For over a hundred years, scientists have been carefully gathering and verifying data on the earth's temperature. The latest data reveals some striking trends:All 10 of the warmest years on record have occurred in the last 15 years The 1990's have already been warmer than the 1980's- the warmest decade on record The global average surface temperature has risen 0.5 degrees (site source)For the first time ever, the Intergovernmental Panel on Climate Change, the authoritative international body charged with studying this issue, concluded that the observed increase in global average temperature over the last century "is

Today we are debating the important topic of global warming. As the affirmative team, we strongly believe that global warming is caused by the actions of humans. But this is not just a belief, this is a fact. Global warming, by definition, is a gradual increase in the overall temperature of the earth 's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants. The greenhouse effect is the trapping of the sun 's warmth in a planet 's lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet 's surface. In simpler terms, this means that the pollution

Through various scientific researches, it has been confirmed that human influence on the climate system is clear and recent anthropogenic emissions of greenhouse gases are the highest in history (Climate Change 2014 Synthesis Report Summary for Policymakers, 2014). The earth has become successively warmer over the last three decades since 1850. Both scientific and observed evidence have shown

       At the beginning of the twentieth century, when global warming was merely a thought to occur among the presence of the greenhouse effect, scientists started to believe it would good for the environment to experience global warming. During the late 1950s, a couple of scientists took further examinations once they noticed there appeared to be a rise of carbon dioxide gas (CO2). Which resulted into the average temperature rise before the end of the twenty first century. Roger Revelle speculated for earth in the twenty first century to encounter a rough effect as soon as the green house effect exerted. After 1960, additional scientists begun to examine when the atmosphere experienced a rapid raise of CO2 (Impacts of global warming, February, 2016).

[Earth’s temperature is definitely warmer than it was hundreds of years ago, but not for natural reasons]. Gradually the Earth’s surface has become warmer over the last century and most scientists believe that the burning of fossil fuels is responsible for the temperature spike. According to Holli Riebeek, the Education and outreach specialist at NASA Goddard Space Flight Center, Global Warming is happening now, and greenhouse gases are responsible. The burning of fossil fuels causes the release of greenhouse gases, which then become trapped inside our atmosphere and cause Earth’s surface to warm. The greenhouse effect provides a habitable environment for all species on Earth, but [the Earth’s atmosphere now contains more greenhouse gases than ever before1]. The Earth is becoming a more efficient greenhouse, which will eventually cause the Earth to become inhabitable. [The natural causes of the warming of the Earth are too minute to explain how rapid the increase in temperature has been in the past 50 years. Between 1906 and 2005, the Earth’s temperature had risen .3 degrees, but in the last 50 years, the temperature increase rate has almost doubled and is predicted to continually increase] (Riebeek). Contrastingly, despite the knowledge and evidence that greenhouse gases are a large factor of Global Warming, some

41, 2008)” With that being said, Greenhouse gases are said to be the main for the climate to be warming up and temperatures rises and causing all sorts of bizarre weather. The environment is hurting because of the rising temperatures on land and sea level. Sea levels are rising due to the ice melting. Many do not believe the climate is being affected by human emissions at all. Greenhouse gases existed regardless but naturally, the environment balances the greenhouse gases. But with the human emission of the greenhouse gases isn’t balanced on the scale anymore. Which is causing the climate to react in absurd ways that has never been seen in the recent history. Many would say that it is just the environment going nuts for a bit, but if it was the greenhouse gases emission would not be as high it is. Greenhouse gases are the main issue causing the global warming problem cause by environments, but they all are linked to the human production of those gases. So a better answer along with the greenhouse gases would be humans.
