The gradual increase in the overall temperature of the earths atmosphere due to the greenhouse effect caused by increased levels of carbon dioxide CFCs and other pollutants. The Earth has experienced numerous episodes of global warming through its history and currently appears to.

Global warming science definition. Though there have been previous periods of climatic change since the mid-20th century humans have had an unprecedented impact on Earths climate system and caused change on a global scale. This phenomenon has been observed over the past one or two centuries. Global warming refers to the increase in the temperatures of Earths oceans and atmosphere.

Global warming An increase in the average temperature of the Earths atmosphere especially a sustained increase great enough to cause changes in the global climate. English Language Learners Definition of global warming. Most scientists believe that the temperature increases are due to the greenhouse effect.

The largest driver of warming is the emission. The recent increase in the worlds temperature that is believed to be caused by the increase of certain gases such as carbon dioxide in the atmosphere See the full definition for global warming in the English Language Learners Dictionary. During the late 1980s one more term entered the lexicon global change This term encompassed many other kinds of change in addition to climate change.

However the concept of global warming is quite controversial but the scientists have provided relevant data in support of the fact that the temperature. As the human population has increased so has the volume of fossil fuels burned. Global warming is an increase in the average temperature of the earth due to the greenhouse effect.

DEFINITION OF GLOBAL WARMING Global warming is understood to result from an overall long-term increase in the retention of the sun s heat around Earth due to blanketing by greenhouse gases especially CO 2 and methane. Machines that we make and other human activities emit pollution which subsequently exacerbates the greenhouse effect. Global warming is the long-term warming of the planets overall temperature.

Study the causes of the greenhouse effect and its importance The greenhouse effect is caused by the atmospheric accumulation of gases such as carbon dioxide and methane which contain some of the heat emitted from Earths surface. These include warming temperatures and changes in precipitation as well as the effects of Earths warming such as. A building mostly made for sheltering delicate plants is called a greenhouse.

Climate scientists have since the mid-20th century gathered detailed observations of various weather phenomena such as temperatures precipitation and storms and of related influences on climate such as ocean currents and the. Global warming the phenomenon of increasing average air temperatures near the surface of Earth over the past one to two centuries. Though this warming trend has been going on for a long time its pace has significantly increased in the last hundred years due to the burning of fossil fuels.

Average temperatures today are about 1 C 18 F higher than before people started burning a lot of coal around 1750. Global warming refers to surface temperature increases while climate change includes global warming and everything else that increasing greenhouse gas amounts will affect. Global climate change refers to the average long-term changes over the entire Earth.

Created and produced by QA International. Global warming is the phenomenon of a gradual increase in the temperature near the earths surface. Climate change includes both global warming driven by human-induced emissions of greenhouse gases and the resulting large-scale shifts in weather patterns.

But in some parts of the world it. This change has disturbed the climatic pattern of the earth. QA International 2010.

Global warming in The Oxford Dictionary of Phrase and Fable. Global warming is the long-term heating of Earths climate system observed since the pre-industrial period between 1850 and 1900 due to human activities primarily fossil fuel burning which increases heat-trapping greenhouse gas levels in Earths atmosphere. An increase in the earths average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect.

Global warming is the temperature of Earth s surface oceans and atmosphere going up over tens to thousands of years.
