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.

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).

Some climate change is natural, yes, but the ones we’re experiencing are not. The global average temperature increased by more than 1.3°F over the last century (Science-Climate Change, 2014). Global temperature shouldn’t be that high. The average temperature in the Arctic rose almost twice as much (Science-Climate Change, 2014). A few other changes are precipitation patterns, increases in the ocean’s temperature, and the melting of glaciers, to name a few. Some of the things we do, like driving, manufacturing, electricity generation, and clearing forests contribute to creating the greenhouse gases and warming the planet (Science-Climate Change, 2014). It also releases carbon dioxide and heat-trapping gases. Road construction and agriculture also contribute to it too (Science-Climate Change, 2014). Greenhouse gases are created by burning fossil fuels, clearing forests, fertilizing crops, storing wastes in landfills, raising livestock,

Whether climate change occurred by human activities or naturally accruing phenomenon is a debatable issue. However, it may safely be said releasing carbon dioxide is one of the main reasons for climate change. Human activities such as the burning of fossil fuels from using transportation and maintaining agriculture are major contributions of greenhouse gases emissions, which lead to climate change. They can be solved by reducing greenhouse gas emissions.

The earth is constantly undergoing changes. This ranges from tectonic activity to atmospheric and climate changes. The most recent change that we have noticed, is the increase in temperature. Some believe that this increase is the result of human activity. However, this is not the case. The increased temperatures are within the normal tolerances from the past few thousand years (Robinson, Robinson, & Soon, 2008). This and other changes to the atmosphere have been going on for millions of years. Global warming is not our fault because it is a natural occurring phenomenon.

How does the rising use of fossil fuels impact the earth? The simple answer is that the earth’s temperature rises, otherwise known as global warming. Global warming then devolves into climate change. Global warming has been “proceeding at a rate that is unprecedented over decades to millennia” (“Climate Change Evidence: How Do We Know?”) because of the world’s increasing reliance on fossil fuels. World-wide natural disasters, such as Hurricane Harvey, may be correlated to an increased risk in extreme weather events due to climate change. There has been efforts to curb climate change, such as pieces of legislation like the Paris Climate Accord, but beliefs of individual leaders such as Donald Trump, who “claims to think that links between carbon emissions and climate change are ‘a hoax’” (Steadman 19), has halted the fulfillment of such agreements between states. If there is not effective efforts to slow the emission rate, the earth will face devastating consequences. Therefore, the leaders of countries across the world must work together to develop a solution to slow climate change, or else the future will be disastrous.

Climate change is not an idea that just popped into existence within the last few years, it has been a political issue since the 1990's but the issue began to raise its head in the 1970's. There are many different factors that play into the greenhouse effect that has wrapped the planet. The most important cause is the gases in the atmosphere blocking heat from escaping. While carbon dioxide plays a part in the greenhouse effect, the most abundant is water vapor while the methane in the atmosphere is far more active than the carbon dioxide will ever be. Nitrous oxide, used in soil cultivation practices, and Chlorofluorocarbons, which are synthetic compounds of industrial origin, also play a part, but on a smaller scale (Global Climate Change:

Climate is sometimes confused with weather, which can lead some people to think that an abnormally cold day can mean that climate change and global warming is a myth. Climate is the weather conditions of an area over an extended period. Climate change is the current warming trend of weather mainly caused by human activities. According to a report written by NASA on global climate change, the main cause of this new human induced, climate change is what’s known as the “greenhouse effect.” The greenhouse effect results when the atmosphere traps gasses, such as carbon dioxide, nitrogen, and methane which causes earth to trap heat (“Global Climate Change”). According to a report by the Washington State Department of Ecology, carbon dioxide and other heat-trapping gasses caused by humans have warmed the earth and are causing many negative

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.

Scientific evidence suggests that human activity like agriculture, urbanization and industrialization have influenced climate change. Clearing land and building cities up for agriculture results in changing the climate. This is because the population is increasing rapidly and the demand to use fossil fuels in our everyday life is also increasing. Increasing use for fossil fuels, industrialization and deforestation has a huge impact on the climate. Enhanced greenhouse gases are an increase in natural greenhouse gases impacted by mankind. The major cause of greenhouse gases is the increase in carbon dioxide, methane and nitrous oxide being released in the atmosphere. If greenhouse gases continue to be produced at the same rate as it did in 2000, then there will be a 0.1-degree change in temperature per decade. This isn’t likely to happen though because of the dramatic need for fossil fuel.

Researches reveal that natural events as well as human related activities contribute to changes in average global temperatures. AtKisson affirms that global warming is basically a result of increased emission of greenhouse gases into the atmosphere. This atmospheric carbon dioxide (co2) comes from anthropogenic (caused by humans) sources. The concentration of greenhouse gas carbon dioxide, nitrous gases, and methane in the atmosphere has increased evidently due to human activities since 1800. NASA’s article adds:

Climate change is defined as the change in global or regional climate patterns, which is apparent from the mid to late 20th century onwards. When looking at climate change there is an abundance of evidence that supports that humans are the leading causes of the drastic shift in the weather pattern but there is also a lot of evidence against humans actually causing climate changes. For example, the increasing levels of man made gases that are let into the atmosphere may have created a greenhouse effect, which traps heat and ultimately causes global warming. But there are also many scientists who believe that the earth has always naturally cooled down or warmed up at its own pace.

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.
