It has also caused poles and glaciers to melt having the sea level rise and low-level island to become flooded. Some seasons are starting earlier or ending later then they where suppose to having plants bloom earlier or start to die. This has caused animals that live off those plants to decrease. Some think that green house gases like carbon dioxide and nitrogen are causing it. Others think cosmic rays, aerosols, natural cycles and models, and galactic cosmic rays are the reason.
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.

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).
As a result of global climate change, regions, ecosystems, and agriculture will be greatly affected. There are many things causing global climate change such as the burning of fossil fuels and deforestation. One may notice that these are both human-related activities. Humans contribute to a vast amount of damage through daily activities. Burning fossil fuels means using energy that is made up of decayed animals and plant matter.

Humans can limit activities that emit green house gases in the atmosphere, and this will help in reducing the increase in the earth’s temperature. This problem has to be properly dealt with or else, it will destroy the entire human, as it is a threat to human existence. Works Cited Cox, John.

Global Warming: “It’s gettin’ hot in here, so take off all your clothes…” The famous words of R&B star, Nelly, are truer than one might think. It really is getting hot in here. The world’s average temperature is rising every year and is expected to be 5 to 10 degrees higher by the end of the century, which is faster than they have increased in the last ten millennia, according to the National Resource Defense Council’s website. But why is this epidemic happening? As the Defense Council states, global warming is caused by carbon dioxide and other types of heat trapping pollution that are collecting like a blanket in the atmosphere, trapping heat from the earth as it tries to radiate back into space.
“Since the industrial revolution began in about 1750’s, carbon dioxide levels have increased nearly thirty-eight percent.” (“Cause of Global Warming”) “ It was not until 1950’s that scientists had discovered that the carbon dioxide levels had increase in the atmosphere and realized it might be a threat. In 1960’s many scientists’ predicted in 2000 the atmosphere would be really bad that it would be the cause of climate change.” (“Global Warming Timeline”) The United States President focused on spreading the news to the nation, but at that time global warming was not a threat so many ignored the signs. However, it was not until 1990 that global warming started to affect the people by climate change. “The effect of climate change on human beings’ health was in focus in 1990s. The issue has not only attracted the experts, but also made the general public worried.” (Moseley Jonathon) Vargas 1 People using cars and factories sending out carbon dioxide in the atmosphere everyday eventually adds up.
Specifically, how will it affect the human population? Are humans causing it? These are but a few of the questions we need to answer when we study global warming. Global warming is the escalation in the average temperature of Earth's near-surface air and oceans that has been occurring since the middle of the twentieth century and its anticipated perpetuation. Global warming is caused when carbon dioxide and other temperature trapping emissions are discharged into atmosphere, and they perform a similar function to a blanket, letting in light but retaining heat in our atmosphere that would otherwise dissipate, resulting in an increase in temperature.
Global Warming and The Environment Global warming is a term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans (All About Global Warming, 2007, para.1). There is no doubt this is an important matter that will impact planet earth for many years to come. Global warming is a critical issue that impacts the entire world and the potential consequences caused by it will have a negative impact if human contribution is not reduced. Although many people disagree with the causes and outcomes, there is certainly enough information available to support the argument. At this time, global warming is said to be a crisis with carbon and emissions of Co2 being made out to be the culprit (Turpin, 2007, p.30).
