Others think cosmic rays, aerosols, natural cycles and models, and galactic cosmic rays are the reason. Some even think that global warming has happened in the past of is happening with the Earth just at its peak in the cycle. How global warming is happening, human caused or natural caused, is the question most people are asking. Human Created Problem Greenhouse Gases Increase of greenhouse gases is one reason why there is global warming. Some greenhouse gases are methane, chlorofluorocarbon, carbon dioxide, ozone, and nitrogen.
Some of the greenhouse gases exist but lately the human activities are releasing an additional of high levels of other greenhouse gases thereby enhancing the greenhouse effect (Haldar, 2011). The world's highest ranked scientists in the field of climate have come to a common conclusion that there is global warming throughout the world. They believe that the cause of the global warming is because of the high levels of greenhouse gases that are being released to the earth atmosphere from the human activities d... ... middle of paper ... ...eat to escape the earth and be trapped in the atmosphere leading to global warming. This leads to the change in the global climate induced by human activities. Works Cited Archer, D. (2012).
“The most plentiful human-generated greenhouse gas is carbon dioxide, released by the burning of fossil fuels.”(Global Warming 2001). The growth in population and mass industrialization have put Mother Nature to her knees, begging for the cooperation of human kind and nature to compromise a fair balance of existence. If global warming continues “Planet earth will turn into our sister planet Venus and temperatures will rise to 250 degrees. We are killing it for future generations to come, and eventually it will be too late for anything to be done. We are leaders that are misleading” (11th hour).
These effects will occur globally and affect everyone. Global warming is occurring, as evidence has shown, with modern civilization a cause: And though its danger exists and its full reversal is improbable, humanity may inhibit it - as mankind’s responsibility. Because global warming poses a threat, global warming’s definition and its associated facts serves as very useful information. Merriam-Webster dictionary defines global warming as “the recent increase in the world’s temperature that is believed to be caused by the increase of certain gases (such as carbon dioxide) in the atmosphere.” Average global temperatures have risen to unusually high levels (Nuccitelli). In the last fifty years, the average temperature of the Earth’s surface has risen faster than ever recorded (Nuccitelli).
This flux in temperature is affected by multiple factors making it hard to determine the true source of problem. Evidence supports that the earth's warming is natural; however, some data indicates that the warming trend has increased due to human activity. Global Warming due to Human Activity Every day human activity has negative effects on the environment. The burning of fossil fuels has released large concentrations of carbon dioxide (CO2) into the atmosphere. Developing countries such as China and developed countries such as the United States (US) are consuming more fossil fuel, thus releasing more CO2 from their admissions (Vital Signs 42).

As radiation comes down from the sun it is absorbed by the Earth. Gases like water vapor, carbon dioxide and methane keep some of this radiation trapped in the atmosphere like a blanket increasing the temperature of the planet. This increase is more commonly referred to as greenhouse effect. The theory of global warming originated in the late 1850's when scientist John Tyndall discovered some gases that block radiation, and trap heat on the earth surface. Just like a greenhouse.
The excessive amount of carbon dioxide in the air was a direct effect of the burning of fossil fuels (NRDC). Global warming is also referred to as climate change. Climate is a measure of the average pattern of variation in temperature, humidity, wind, precipitation, and other variables in a given region over a period of time. The climate of Earth has been noticeably increasing since the Industrial Revolution (School, Climate Change, 2014). Scientist can tell climate change using a couple of different kinds of methods.
Global warming is the increased warming effect of the atmospheric temperature resulting in a change of the Earth’s climate (USGS.gov, 2008). The increase warming of the temperature is the result from two greenhousegases such as carbon dioxide and methane that are being filtered and trapped into the Earth’s atmosphere. The layers of Earth’s atmosphere is to protect life from high-energy radiation and the frigid vacuum of space (nasa.gov, 2010), but if the atmosphere’s layers becomes thinner, its vital role of protection will diminish. Landfill wastes, industries and deforestation are why global warming exists, in turn will affect all life on Earth.
