Global Warming Middle 1900's

Global warming is the recent and ongoing rise of temperature on a global scale. Over the past century, the Earth's average temperature has risen 1.4°F (Carlowicz, 2010). Global warming is the effect of an excessive amount of greenhouse gases in the atmosphere. Greenhouse gasses trap heat from escaping back into space to keep the Earth from freezing, this is called the Greenhouse Effect. An excessive amount of greenhouse gases in the atmosphere trap too much heat, thus, causing Earth's temperature to rise.

Global warming is defined 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. There are many different theories on whether global warming is similar or not to climate change. Simplistically, climate change is different because climate change is defined as a change in global or regional climate patterns or, in particular, a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels, having been measured over long periods of time, due to the changes in Earth’s orbit and organic carbon which reflect sunlight. Global warming and climate change are not to be confused because global warming is caused mainly by anthropogenic factors like the emission of carbon dioxide gas and use of fossil fuels whereas climate change is completely natural, however, according to Milan Radovanovic, “it is clear that the anthropogenic factors dominate the increasing temperature and the natural ones have the maximum influence…” (Radovanovic). Therefore, “the contribution to global warming from natural forcings and from natural internal variability is in the range between -0.2 to 0.2 [degrees] celsius over the period 1951-2010…” (Radovanovic). Natural factors have had the most effect on global temperature in the past 59 years totaling a 0.4 degrees celsius increase in

Global warming is a gradual increase in the average temperature of the earth's and its oceans and a change that is believed to permanently changing the earth’s climate.

Global warming is the rise of average temperature in the earth’s atmosphere since the late 19th century. Since the beginning of the early 20th century, the earths mean surface temperature had increased by around 0.8 degrees. Warming of the climate system had become more obvious and scientists are 90% sure that the main cause of the increase in temperature in due to the increasing concentrations of greenhouse gases due to human activities such as deforestation and burning of fossil fuels.

Global warming is a term used to describe the slow change in Earth’s overall temperature. This topic recently started being heavily recorded and studied by scientists. Politics started including it around the 1990’s. The boost of greenhouse gases caused by human burning of fossil fuels, industrial farming, and deforestation activities are what people tend to blame for

“Global warming refers to the recent and ongoing rise in global average temperature near Earth 's surface. It is caused mostly by increasing concentrations of greenhouse gases in the atmosphere. Global warming is causing climate patterns to change. However, global warming itself represents only one aspect of climate change” (Climate Change, EPA.gov).

Global warming is the increase of Earth's average surface temperature due to greenhouse gases that collect in the atmosphere, trapping the sun's heat and causing the planet to warm up

Global warming is a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants. (What is global warming, google.com). Scientists have stated that the rise in average temperatures worldwide since the late 1800s. Earth's temperature has gone up by 1.4 degrees over the past century, according to the Environmental Protection Agency. Temperatures are to rise another 2 to 11.5 degrees over the next 100 years (what is global warming, livescience.com). Human are one of the main causes for global warming, all of the cars, factors and electricity production they have created. They have also created Greenhouse which gases

Global Warming is an increase in the average temperature around the world. Scientists have been able to trace the global climate and concluded that over the last ten thousand years, the climate of the earth has been relatively constant. In the twentieth century, the global temperature increased 0.740°C. The change in the warming, and cooling, of average global temperatures cause climate change, a change related to climate patterns such as temperatures, rainfall, wind and humidity. 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.

For the past few years Global Warming has been an issue that continues to worry Scientists from all over the world to this day. Global Warming is a gradual increase in the overall temperature of the Earth’s atmosphere generally attributed to the greenhouse effect caused by higher levels of Carbon Dioxide. Many people believe that Global warming is the one thing that is causing ice to melt on Earth.

Global Warming is the increase of Earth's surface temperature due to effect of greenhouse gases, such as CO2 emissions from burning fossil fuels

Global warming is a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants. The Green House Effect is the process in which the absorption and emission of infrared radiation by gases in the atmosphere warm a planet’s lower atmosphere and surface. These greenhouse gases traps some of the heat emitted by the Earth.

Global warming refers to the gradual warming of global-average temperatures due to the slowly increasing concentrations of man-made atmospheric greenhouse gases, primarily carbon dioxide. But global warming can alternatively refer to simply the observation of warming (Weatherstreet, 2013).

Global warming is the most talked topic in our time. It is the increasing temperature of Earth’s surface, oceans and atmosphere. There is an evidence that shows earth temperature increased by 1.4% since late 1800s, which sounds small number but scientist predicted the temperature will rise another 2 to 11.5 degrees F over next 100 years.

Merriam-Webster defines global warming as an increase in the Earth 's atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting
