Human Impact On Climate Change

First, an overwhelming scientific consensus agrees that human activity is primarily responsible for Global Climate Change. A study in 2010 showed that 97-98% of researchers agree that human activity is the primary cause for climate change around the world. This study also found that the expertise of researchers unconvinced was “substantially below” the researchers that were. The 2013 Cook review showed that out of the 11.944 studies, less than 1% completely rejected the possibility of humans causing this. A different review of 13, 950 studies of climate change found only 24 that rejected humans causing climate change. Let’s just go with majority rules. A different study held by Bray and Von Storch, two German scientists, showed that 83.5% of scientists studying climate believe that humans are causing the recent amounts of climate change. Also, a study in 2011 showed that 84% of scientists studying earth, space, the atmosphere, oceans and hydrology believe that human caused climate change is

Climate change is evident throughout the world and is a major issue. It is no secret that our planet is getting warmer. Global warming is now recognized in the scientific community as a real problem. There are multiple aspects that are causing this issue. Majority of the warming is caused by greenhouse gases. Volcanic eruptions and changes in the intensity of solar radiation have offset the warming partially. It is estimated that average annual temperatures will increase 3.5°F-9.5°F by the century’s end.

But many climate scientists will tell you that this change in climate is due to humans and their activities. It is said that humans release greenhouse gases and “if emissions continue unchecked, they say the global warming could ultimately exceed 8 degrees Fahrenheit, which would transform the planet and undermine its capacity to support a large human population” (Gillis, 2015). To make it easier to understand, as sunlight reaches the Earth’s surface there are two things that can be done, one; it can either be reflected back into space or two, it can be absorbed by the Earth. Once the Earth absorbs the sunlight, it then releases some energy back into the atmosphere as infrared radiation, also known as heat. Then these greenhouse gases tend to act like a “blanket,” therefore making the Earth warmer than it would be otherwise. This process is what we call the “greenhouse effect.” The reason scientists say that climate change is caused by humans is that it’s simple, humans drive, cook food, and even heat or cool their homes, which release gases such as, carbon dioxide (CO2), methane (CH4 ), and water vapor (H2O).

There are always two sides to every story and every different point of view has a right to be heard. When it comes to the discussion of global warming—a gradual increase in the earth’s surface temperature—there are two very distinct and opposing points of view. The world seems to be split between global warming being caused by humans and it being a natural occurrence; the latter being the viewpoint that I strongly support due to the evidence I will present in detailin this paper. In contrast, I will also discuss, in Part II, the “anti-thesis” or the opposing viewpoint that humans are actually the

The Earth's climate has changed throughout history. According to the findings of National Aeronautics and Space Administration (NASA), the change of the earth’s climate has evolved through time. The global sea level rose about eight inches in the last century; the planet's average surface temperature has risen about 2.0 degrees Fahrenheit since the last 19th century; the oceans have absorbed much of this increased heat of 0.302 degrees Fahrenheit since 1969; the increasing number of record high temperature and intense rainfall events since 1950; and the overall increase of ocean acidification by about 30 percent. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives. The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century. There is no question that increased levels of greenhouse gases cause the Earth to warm in response.

At the outset, there are numerous reasons why the climate change is probably caused by human activities, and the most conspicuous one stems from the fact that the phenomenon became increasingly obvious as the technology advances. For example, a recent seminar conducted by the University of Sydney manifested that the pullution is

Climate change is a global problem that is affecting Earth’s delicate ecosystem. Many problems are present in our world today, such as starvation, flooding, heat waves, droughts and disease. These issues are likely to worsen as climate change takes its toll. In the past, the cause of this severe climate change was unknown. Today, it is known that manmade climate change is occurring. Scientists have discovered that humans have had the greatest impact on the Earth’s ecosystem. Human activities, such as burning fossil fuels and deforestation, are causing the Earth to get hotter. Although humans are not the only cause of climate change, we contribute to this world wide problem because of the actions we take, which if affecting us now and will continue to affect us in the future.

In the last 100 years, Earth’s average temperature has risen by 1.4°F. The rising global temperatures have caused changes in weather and climate. Global warming refers to the ongoing rise in the average temperature near Earth’s surface. This is causing a climate change, which refers to any significant change (major change in temperature, precipitation, or wind patterns) in the measures of climate lasting for an extended period of time (several decades or longer). Due to this, it is projected that the temperature will rise from 2 to 11.5°F in the next hundred years (US EPA, 2014). The “drivers,” which are the principal causes making this occur, are very controversial. It is debated whether a change in temperature is due to the work of

The climate of earth has been increasing for past decade. The increasing temperature is not only harmful for environment but also dangerous for earth and peoples' survival. However, many international societies and groups have been putting their efforts to keep the atmosphare balanced, they are not enough. I believe people are the main cause of pollutions, destroy forests, and natural habitat. Therefore, atmosphare has been changing drastically.

Over the years there has been a lot of controversy on if climate change is an issue that needs to be discussed and solved. There is a constant debate among scientist on if human actions are contributing the changing of earth’s climates. Climate change is defined as the change in average weather patterns for a specific region or Earth as a whole. This could include the change in an average temperature for a city or the amount a rainfall it receives (Dunbar, 2015). The main difference between weather and climate is the period of time specific patterns are recorded. Weather patterns are looked at over a much shorter period of time, meaning that these patterns are going to be more sporadic and change more frequently. Climate on the other had is recorded over a much longer period of time and usually show less drastic changes in patterns when compared to weather. Some people may argue that climate change is not an issue because Earth’s temperature is always changing do to natural effects. What people don’t realize is that human activity has effected the rate that earth’s temperature is changing, and just the smallest changes can lead to drastic consequences (Dunbar, 2015).

Despite the controversy that surrounds the existence of climate change, there is a high agreement among scientists that human-caused climate change in very real. Over the past two decades, surveys and studies have been done on climate change and the results have shown that the average global temperature has increased by about 1.4 degrees Fahrenheit. The sea level is also rising and heat waves are happening more frequently than before. These events could lead to an abrupt and potentially irreversible climate change but scientists do not know the tipping point for such an event. Therefore, the sooner the inhabitants of earth begin to take action against climate change, the less likely something irreversible could happen.

We all see the weather change from day to day and it is just a normal occurrence. Seasons change from warm to cold and we all just go about our business. But what most people don’t see change is the climate. Climate changes over a long period of time and it has shown a warming trend in the past few decades. Many people attribute this warming trend to the alarming rate that humans are burning fossil fuels and pumping Co2 into the atmosphere, however some people think that climate change is merely a myth or that global temperatures have always risen and fallen during Earth’s lifetime.

The planet has been experiencing considerable climate change for the last several decades. There have been many explanations toward the main causes of the increased warming of the planet. On one hand are the environmentalists who believe that the major cause of this increased warming of the planet is the increase in greenhouse gases in the atmosphere induced by human activities. On the other hand, the scientists believe that there are natural causes of global climate change. While the supporters of the man-made theory of global climate change reason that the major greenhouse gas causing global warming is carbon dioxide, the advocates of natural causes

Global climate change has become an undeniable and unavoidable reality. In its latest assessment report, the Intergovernmental Panel on Climate Change, the international body that provides the most comprehensive reports dealing with the science of climate change, has established that warming of the climate system is ‘unequivocal’. Additionally, it concludes that human activities such as land clearing and burning of fossil fuels have increased the concentration of greenhouse gases in the atmosphere to unprecedented levels (IPCC 2013).

Most of the blame for climate change over the years especially after the 1850’s has been placed on humans. As long as modern humans have roamed the earth, they have been upsetting the natural balance of the earth. People have did this by clearing areas of land, killing animals, polluting water, etc. Before the “modern human”, people like the Native Americans cared for the earth. They respected the land and the people that cared for it. Unfortunately, people don’t care anymore. Until recently, people did not care for the earth. People did not realize the harm they were causing it. Now we know how detrimental things are that we continue to do and used to do.
