What Global Warming Is
As a definition, 'global warming' is the rising of temperature on Earth's surface and atmosphere. This definition has been applied to a controversial issue about why and how that increase in temperature is happening.
Global Warming is the result of not paying attention to the signs, it is the gradual increase in global temperature caused by the emission of gases that trap the sun's heat in the Earth's atmosphere. Gases that contribute to global warming include carbon dioxide, methane, nitrous oxides, chlorofluorocarbons (CFCs), and halocarbons (the replacements for CFCs). The carbon dioxide emissions are primarily caused by the use of fossil fuels for energy.
Global warming is an observed increase in the average temperature of the Earth's atmosphere and oceans. Part of this increase may be due to natural processes, such as the solar cycle, and would have occurred independently of human activity.
