The main source of the increased levels of carbon dioxide in the atmosphere is the burning of fossil fuels, causing 75% of the increase.

on, there are other, natural forcings that have effects on the global climate. A few of these

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

“CO2 gas emissions” is a mystical term which everyone should pay attention to. C02 gas is a colorless, odorless gas that is present in the atmosphere and is formed when any fuel containing carbon is burned. Plants and trees are using it in the process of photosynthesis. Carbon dioxide is also used in refrigeration, fire extinguishers, and carbonated drinks. In other words this is the gas we need to fight with! By using fossil fuels in almost everything we do, we make a huge cloud of gas and this is warming up the world. By doing this, we cause serious damage to the nature and we may have an irreversible effect on it and the future.

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.

Climate change has been in the news for years. Earth's average temperature has risen by 1.4°F (0.8 degree Celsius) over the past century, and is projected to rise another 2 to 11.5°F (1.1-6.6 degree Celsius) over the next hundred years. The main cause of climate change is due to the increase of greenhouse gases. Since the beginning of industrial revolution in 1750s, human have released large amount of greenhouse gases mainly carbon dioxide into the atmosphere.

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.

Carbon dioxide is very important in the atmosphere, however only in moderation. For centuries humans have been burning coal, oil, and fossil fuels therefore releasing tons of carbon into the air. The problem with this is that this can cause a problem known as global warming. This is a major climate problem, which has series results on people and the environment. The result on people can be very deadly. Too much carbon in the air can cause cancer.

Without this layer of gases the Earth would be too cold to be inhabited, perhaps 20 degrees cooler than now. But, then amount of gases in this layer must remain constant. Even a slight increase could have drastic results. Many people believe that a one degree increase in the temperature will not cause much harm. The truth is with every degree of increase in temperature a 100 more wildlife species are put in danger of extinction. Numerous experiments and studies prove that an increased level of greenhouse gases, mainly carbon dioxide, is causing climate change and causing it fast.

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.

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

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.

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

What has changed in the last few hundred years is the additional release of carbon dioxide by human activities. Fossil fuels burned to run cars and trucks, heat homes and businesses, and power factories are responsible for about 98% of U.S. carbon dioxide emissions, 24% of methane emissions, and 18% of nitrous oxide emissions. Increased agriculture, deforestation, landfills, industrial production, and mining also contribute a significant share of emissions. In 1997, the United States emitted about one-fifth of total global greenhouse gases.

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.
