We ask ourselves how might human activities have affected global climate change? Well human activities contribute to climate by causing changes in earth's atmosphere in the amounts of greenhouse gases and cloudiness. Mostly it is burning fossil fuels. This releases carbon dioxide gas to the atmosphere. There are many ways that the humans can affect our environment. Deforestation, burning fossil fuels, and hydrocarbons are ways this can affect. In this paper i will explain how each one contributes to global warming. I will support my discussion with evidence and consequences of the effects of each activity. It will also have alternate energy and solutions included that are most sustainable in our area.

The human race all around the world wonders if the climate is changing due to human activity or if it is just a natural occurrence. At certain parts of the Earth's surface, the climate can be observed much differently than other locations. As the years go by the average temperature of the Earth increases by little intervals. There are several different reasons why people believe the climate is changing every year. However, the increase of worldwide population and production of heat to the atmosphere is due to the increase of human activities that take place on a daily basis. Human activity is the main cause of the global climate change. The human impact on climate exceeds any known changes due to natural processes. The impact of this human activity is often misunderstood when looking at climate change.

People have come with varied causes of global warming. Some natural causes are the release of methane gas from the wetlands and the arctic tundra. It has been proposed that the temperature of the earth is influenced by the activities that man carries out. (Michaels 222) Others have proposed that this is due to the climate change that the earth goes through after a certain amount of time.

The primary cause of climate change is the burning of fossil fuels (oil and coal) which emits greenhouse gases into the atmosphere (mainly carbon dioxide) (What is climate change 2014). In addition, other human activities such as deforestation and agriculture also contribute to the proliferation of greenhouse gases, which cause Climate change (What is Being Done to Stop Climate Change).

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.

The burning of fossil fuels such as coal and oil, and deforestation over the last 200 years has caused the concentrations of heat-trapping "greenhouse gases" to increase significantly in our atmosphere. These gases prevent heat from escaping to space. Greenhouse gases are necessary in our lives as they help in keeping the planet 's surface warmer than it would otherwise be. But, as the concentrations of these gases continue to increase in the atmosphere, the Earth 's temperature is climbing above past levels (USEPA, 2014).

The global warming is a phenomenon happening all over the earth, there are several causes, but most are a result of human activity. The graph in image 1 shows that a significant increase in the climate temperature in the mid-20th century, somewhere between 1900 and 1950. The industrial revolution happened between the years 1820 and 1840, although great improvements in technology were achieved in the 1900 's. The increasing temperatures since the industrial revolution work as a proof that global warming is a direct effect of human activity. As image 1 shows before the 20th century the variations in the earth 's climate were minimal, except for that of the ice age. Although the industrial revolution detonated the rising temperature due to the use of new chemicals, this change is not evident until it surpasses the previously registered temperatures in the mid-1900 's. Science and technology have improved in the last 200 years, most devices used to measure changes in temperatures were just developed about 150 years ago, so there is not much information of the temperatures before that (Vallis). Nevertheless, scientists have been able to estimate the earth 's temperature from millions of years ago by studding trees, fossils, sediments and water temperatures. Recent studies have proved how many man-made chemicals and activities have contributed to the climate change, affecting the natural processes in the earth like the

Like many of us the letters EPA spark interest and a sense of security. For those of us who do not know what or who it stands for it is the U.S. Environmental Protection Agency. This agency continues to clear up what is fact or fallacies. For example, most Americans believe Bottled water to be pure and safe. There are some chemicals in the battled water as well as tap water. According to Cynthia Dougherty the director of EPA, “The EPA is stating that the United States has one of the safest water supplies in the world and that we have a very, very high assurance of safe, high-quality drinking water (Lunsford 717). It’s with her statement about how safe regular tap water is due to the use of similar-chemicals found in bottled water. However, we find within her comments regarding tap water, not all being 100% safe in some cases such as on Indian Reservations or in a few cities were the EPA regulations may not be in compliance.

Although global temperature fluctuation does happen naturally, the main cause for the significant increase in overall temperature after the industrial revolution is believed to be caused by humans. Earth is protected and warmed by greenhouse gases in the atmosphere that prevent heat radiated from Earth from escaping into space. There are several greenhouse gases in the atmosphere, but the one responsible for global warming due to the greenhouse effect is carbon dioxide or also known as CO2.

These increases are due to fossil fuel burning, a human activity that produces carbon emissions. This is one of the reasons as to the statement made by the Intergovernmental Panel on Climate Change that it is extremely likely that human activity causes global warming, an over 95%

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

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.

Global warming has been an on-going issue for many decades. Most people would argue that it is a hoax; while others argue it is true. Climate change can cause a domino effect of catastrophes throughout the world. Once it affects one group, then that affected group will affect another, and so on and so forth; like a plague. Global warming is an authentic problem and we need to find more efficient ways to eliminate it, or at least contain it.

Global warming is a sizable threat, no doubt, but it is not as scary as people like to think that it is. There is solid evidence that shows that global warming is not new. In fact, scientists have strong reasons to believe that it has happened bounteous times before. The researchers at Harvard-Smithsonian Center for Astrophysics have done

According to a recent study, humans having been causing global warming for about 180 years. The study reconstructed 500 years of climate to determine when the warming shift started. They found that the earliest stages of human-caused greenhouse warming began in the Industrial Revolution, mainly around the 1830s in the Arctic and tropical oceans, followed by change in North America, Europe, and Asia. At this time in human history, we has started burning fossil fuels like coal. This was used to power factory machines, and steam engines used in trains and steamboats. Fossil fuels originate from the remains of ancient plants and animals, and when burned, release carbon-dioxide and other greenhouse gases in the
