The Carbon Cycle

Every year the average American produces over 22 metric tons of CO2 living a normal life (“What is Carbon Neutrality,” 2008); and the United States as a whole produces 6,049,435 metric tons of CO2 yearly (“List of Countries by CO2 Emissions,” 2010). This disturbing figure is the main cause of global warming and we have yet to take responsibility for our actions. There are many different theories of what has caused global warming and the answer is mankind. Humans are the cause of global warming because of pollution, over population, and deforestation.

Worldwide temperatures are rising, carbon dioxide is at a hazardous level, ocean acidification, atmosphere boundary shifts, and extreme events are just a few of the worldwide climate changes happening near and far. It is a controversial issue whether it is taking place in the present velocity because of nature or man. However, global climate changes happen naturally, but they ought not to happen at this increased rapidity; therefore, human activity is a great cause that global climate change is happening at an expanded rate. The greatest contribution of human action is the combustion of fossil fuels, which is one of the primary reasons why the carbon dioxide levels are nearing high-hazard strata. Thus, the scientific confirmation supports that the rise in carbon dioxide levels is significantly generated by people, not nature, and people are ultimately the largest contributor to the atmospheric changes; thus, human beings should implement changes to their energy sources and modify agricultural production in order to lessen the quantity of carbon dioxide emitted into the aura at the extraordinary rate it currently is passing.

When trees are burned, CO2 is relinquished. The burning of astronomically immense areas of trees is known as deforestation. Human activities integrate more CO2 into the atmosphere through activities like the burning of fossil fuels. The guiding question of this investigation is, “Which carbon cycle process affects atmospheric carbon the most?” The researchers initially wanted to learn 2 things. First, the researchers wanted to learn how much carbon engenderment there would be if they incremented the amount of fossil fuels burnt by a certain amount. The researchers also wanted to learn how much carbon engenderment there would be if they incremented the amount of deforestation.

Main Point - Despite the fact that a specific amount of carbon dioxide (CO2) happens naturally in the Earth's atmosphere, there are many human activities that boost the levels of the greenhouse gases causing it to be harmful to Earth`s climate.

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.

Secondly, together with deforestation of the planet, the burning of fossil fuels is contributing to a measurable increase in the concentration of carbon dioxide in

28. What are your thoughts regarding the role humans and the burning of carbon-based fuels in global warming? This is an opinion question

Even though many countries worldwide have pledged to stop adding more CO2 to the atmosphere, global climate change is inevitable and temperatures will surely rise after 200 years of intense pollution

Today, atmospheric CO2 concentration has nearly increased by 25 percent, and the global temperature has risen by nearly 1.25 degrees as reported in 2014 (U.S. Global Change Research Program, 2014), as part of a continuous rise since the 1800s. This may seem small but are having a huge effect on the Earth and causing global warming, and in turn, climate change. These changes are predominantly blamed on humans, through actions such as fossil fuel consumption, deforestation, and increased agricultural production and

Human activity has altered the global carbon cycle in multiple ways. One of the most impactful ways that the carbon cycle has been impacted is thru the use of fuels has added an abundant amount of carbon dioxide to the world. This is a major concern because this is dangerous to human life, but it adds to global warning.

Climate change is a challenge facing our planet right now. Long-term effects may develop as a result, causing threats to natural resources, human health, and the economy. The concern is rising with the amount of carbon emissions and greenhouse gases in our delicate atmosphere.

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

Humans are burning fossil fuels to power their cars, their housed, etc. which emits carbon dioxide

In this lab we explored the effect a given individual has on the issue of global warming. In part A, which determined the individual output of CO¬2 per year, we measured the mass of the CO¬2 that completely filled the plastic bag, as well as the elapsed time from start to end. From that data, we concluded that a single person can produce about 5.06 x 105 grams of CO2 per year. Although that may seem like an enormous amount, in perspective of the vast size of the Earth’s atmosphere, it barely constitutes 1 percent of the atmosphere. In the second part of the lab, we calculated the amount of CO¬2 that is produced by cars in a year. In my case, my Honda Odyssey travels about 13000 miles per year with a gas mileage of about 25 miles per gallon.

Managing the terrestrial C cycle is one of the major problems that monopolize the interest of the scientific community for the last years. Estimating the size of carbon sinks or sources, it is not only scientifically important but also attracts the public interest since it is related to Kyoto Protocol which aims to reduce the fossil fuel emissions in the atmosphere (Fang et al., 2007). The global carbon cycle has significantly altered since the industrial era (Churkina, 2013) and the C02 concentrations from 1750 since 2011 show an increase of 112.5 ppm. The land use change emissions and the fossil fuel emissions, which are caused due to human activity, increased the atmospheric CO2
