The gases are emitted mainly by cars, power plants, and other industrial sources that burn gasoline, coal, and other fossil fuels. Obviously, the emissions of these greenhouse gases in excess are leading to the planet’s consistent increase in temperature. For example, in a study conducted by the National Center for Atmospheric Research, it was confirmed that earth’s early century warming was caused by mostly solar and volcanic forcing, and the late century warming, from 1940-2000, was mostly caused by the increase of greenhouse gases. The National Resource Defense Council states, if global warming persists, there will be more air pollution and problems with water supplies as precipitation patterns change, as well as huge threats to ecosystems from the Everglades to the glaciers. Not only will there be hotter, longer heat waves and more intense storm systems, but also forests, farms and cities will face troublesome new pests and more mosquito-borne diseases.
Although CO2 is absorbed and emitted naturally through animal and plant respiration, volcanic eruptions, and ocean-atmosphere exchange, atmospheric CO2 emissions have increased nearly 40% from pre-industrial times. The increase is largely due to human activities that include the burning of fossil fuels and changes in land use that require deforestation (EPA). The effects of global climate change on the environment are very real and already observable. In the past, some of the things scientists had predicted that global climate change would cause were loss of sea ice, accelerated sea level rise and longer, more intense heat waves. We are witnessing those changes now.
Global warming will change the Earth in unimaginable ways. With the ever increasing amount of Greenhouse gasses in our atmosphere, glaciers are now melting rapidly causing sea level to rise. The coastal changes will be sure to change our living environment over the next few hundred years. Global Warming is a phenomenon in which the temperature on the Earth increases. Over history we see natural stages in our Earth’s climate between warm and cold periods because of increased Carbon Dioxide.
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).
The majority of scientific studies indicate that the main cause of global warming is, increased levels of carbon dioxide into the atmosphere. Some research shows that natural occurrences are the main source of global warming. This essay will argue that carbon dioxide released into the atmosphere, by man-made actions is the main reason for the global temperature changes, secondary, are natural occurrences. Some believe that, carbon dioxide in the atmosphere causes a warming effect on the atmosphere. This carbon dioxide, as the majority of studies have shown, has contributed to the rise in global temperature.
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).
Abstract There needs to be a reduction if not extinction with the increasing amounts of carbon dioxide, methane, chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), per-fluorocarbons (PFCs) and nitrous oxide into the atmosphere because it is directly affecting global warming. The combustion of fossil fuels and greenhouse emissions mainly contribute to the increase of these gases. The longer we go without solving this global problem the more conflicts we will have in the future. Although global warming does make the earth warmer there is more to worry about than heating to death. Major concerns revolve around effects on agriculture, water resources, ocean level and coastal regions, and disease.
Is global Warming Real? What is Global Warming? Why is it important, or not important? Well, global warming is the gradual increase in the temperature of the earth’s atmosphere generally attributed by the increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants. Global Warming is real and is a current problem that we live with every day.
(IPPC, 2007) Global average temperature rise significantly during the past century. The prevailing scientific view is that mainly of the increase of temperature since mid-20th century has been caused increase in atmospheric greenhouse gas concentration produce by human activity. The majority scientists believes that planets temperature has risen 0.5 degree Celsius since 1990 and will continue to increase at an increasing rate.

Global warming occurs when the levels of greenhouse gasses rise and less infrared light, or heat, escapes the earth's atmosphere. Thus, the temperature experienced on Earth begins to rise. Climate change is a part of the Earth's history. There have been dramatic fluctuations in overall average temperature for the past 150,000 years that suggest a direct association with carbon dioxide levels. In the past the temperature highs and lows have been in tandem with carbon dioxide level highs and lows, this does çijopnot seem to be a mere coincidence.
