Analysis Of ' Earth 's Blanket '

The first reason humans are the cause of global warming is because of pollution. Pollution is one of the biggest manmade causes of global warming and it comes in many shapes and sizes. The burning fossil fuel is one thing that causes pollution. Fossil fuels are a non-renewable source of energy, such as coal, oil and natural gas and when they are burned they give off a greenhouse gas called CO2 (Chughtai, 2008). We as humans release CO2 from power plants,

Humans are to blame for global warming, there is no question about it. Humans and human actions are causing a rise in temperature worldwide. We have recorded a steady rise in temperature for the last fifty years. This rise is caused by an estimated 95% of human actions.Humans are to blame for global warming because of deforestation, population growth, and the use of non-environmentally safe products.

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.

In the last century the climate of the earth has morphed and changed as a result of global warming. The rise in temperature has contributed to the decreasing size of glaciers and ice sheets as well as contributing the the rise of sea levels due to warmer oceans. The current evidence points to human activity as a contributing factor. With the evidence currently available if can be predicted that with continuing greenhouse gas emissions, the earth 's air temperature will warm by 4°C by the year 2100. Furthermore there are likely to be many flow-on effects from this temperature change (Australian Academy of Science 2015)

There are many factors and catalysts making small inclinations and changes within global temperature, but mankind has been the biggest, causing detrimental harm to the world in global warming. Throughout history there are natural causes that factor in small and short term climate change, such as the occasional volcano erupting, or an excess of greenhouse gases in the air, which are gases that help absorb radiation, which as a result keeps heat within the atmosphere, having a warmer net temperature. Annually there are many fluctuations that cause minor altercations within but humanity doesn't help either. During post 1850s since the industrial revolution, the significant uses of coals, oils, and fossil fuels, have caused an exponentially increasing amount of carbon dioxide to be released

A scientist that reports for National Geographic Magazine stated, “Since 1990, yearly emissions have gone up by about six billion metric tons of “carbon dioxide equivalent” worldwide, more than a 20 percent increase”(“Causes of Global Warming”) Humans are the cause of global warming. Overpopulation of the human race has resulted in a multitude of carbon dioxide gas getting trapped in the atmosphere, warming the earth as if it was a greenhouse. Carbon dioxide (Co2) is a “waste” gas of human beings. One human approximately exhales two and one third pounds of carbon dioxide gas a day(Palmer) Consequently, the gas is warming the earth from the core up. Humans are the cause of global warming.

The Milankovitch Mechanisms are central to long-term climate history discourse (Berger, 2013) and incorporate three orbital changes, which are named Precession, Eccentricity and Obliquity. Eccentricity is the first Milankovitch Mechanism, whereby the orbit of the Earth around the sun varies from a nearly perfect circular shape to a more elliptical shape (Figure 1A). At its most elliptical orbit, the Earth passes ~6 million miles (Scofield, n.d) further from the sun at the point of aphelion, and subsequently, the winter climate would be extremely cooler due to the reduction in incoming solar radiation. With Eccentricity, the insolation received can change by ~30% (Maslin and Ridgwell, 2005) and occurs at cycles of ~100,000 years (Maslin and Ridgwell, 2005). Obliquity is the second Milankovitch

Global warming is a broad term that describes the massive global increase in temperature in the last couple hundred years or so. Most scientists agree that there has been a massive spike in the emission of greenhouse gases in those last few hundred years. What they do not agree on is if humans are primarily the cause of the increase in temperature because of our bad habit of dumping greenhouse gases into the atmosphere. Some say that the increase in pollutants is causing the warming, while others say that the amount of gases humans have released into the atmosphere is not enough to affect the world on such a large scale. Unsurprisingly, scientists are deeply divided on one of the biggest problems of the last few decades. Steps have already

Global warming is being caused by humans, not the sun. What is global warming? Carbon dioxide and other air pollution that is collecting in the atmosphere like a thickening blanket, trapping the sun's heat and causing the planet to warm up. Coal-burning power plants are the largest U.S. source of carbon dioxide pollution -- they produce 2.5 billion tons every year. Automobiles, the second largest source, create nearly 1.5 billion tons of CO2 annually. The planet is changing faster than expected, with the earth getting hotter, and coal-burning power plants are to blame for the largest amount of carbon dioxide pollution.

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:

Human activity over the last century have caused major detrimental changes to the climate with carbon dioxide and other greenhouse gases being emitted into the atmosphere. These changes to the worlds ecosystems and could involve key human health problems. There is worldwide scientific consensus and proof that climate change is real, evidence proves there has been 7 cycles of glacial advance and retreat, since the beginning of the modern climate 650,000 years ago. The evidence of our changing climate is from many forms of data collected over years ago [EV]. According to this evidence, we are exponentially increasing the rate of temperature at which Earth is heading for.

The climate of our world is changing, but why? There is a great debate going on in the scientific community on whether our current climate change crisis is a natural occurrence over millions of years – as what has happened on the planet of Mars – or this natural process is being accelerated by man’s negligence. But first we must establish what is climate change? Climate Change is a long-term shift in the statistics of weather (taken from weather.gov October 2007 article on Climate Change). Throughout our planets long history our climate has changed between hot and cold in each time period from the Precambrian period to today. The Earth’s climate

While humans might not be solely to blame for global warming, we definitely have a major role. Most are familiar with the burning of fossil fuels (coal, oil, and gas) as a major contributor to the overall C02, although, just as equally important is that of deforestation. It was realized that “conversions of land use, primarily deforestation in the tropics, induce substantial terrestrial carbon losses to the atmosphere, approximately 1.6 billion tons annually” (Broadmeadow, Freer-Smith, & J. Lynch, 2007). While the cause of deforestation varies in different regions, the key contributors are cutting down tree to open up more land for agriculture, urban sprawl (Turk & Bensel, 2011). Forests work like filters to remove CO2 from the air and store it in the trees. When the trees are felled or burned, huge amounts of CO2 are released into the atmosphere at a rapid pace.

Has it been feeling warmer every summer? Do the winter months seem to last shorter? These things are happening and the environment is being destroyed as a result. Factories and cars are spitting out carbon dioxide and other greenhouse gasses which heat up the Earth like an oven. Big company owners are paying billions to slip around laws and cut corners to make a little more money. This is a real problem that most people commonly known as global warming. In order to understand global warming the public needs to know what global warming actually is, how farming, clearcutting, and pollution impact the Earth, and solutions to these problems.

Human activities are contributing to global warming by adding large amounts of heat-trapping gases to the atmosphere. Our fossil fuel use is the main source of these gases. Every time we drive a car, use electricity from coal-fired power plants, or heat our homes with oil or natural gas, we release carbon dioxide and other heat-trapping gases into the air. The second most important addition of greenhouse gases to the atmosphere is related to deforestation, mainly in the tropics, as well as other land-use changes.
