In the 1980s the terms global warming and climate change were popularised the former referring only to increased surface warming while the latter describes the full effect of greenhouse gases on the climate. Within scientific journals this is still how the two terms are used.

A long-term change in the Earths climate or of a region on Earth.

Global warming definition nasa. 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. The Earth has experienced numerous episodes of global warming through its history and currently appears to be undergoing such warming. Global warming is the long-term warming of the planets overall temperature.

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. 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. The temperature of the earth has been going up and down for millions of years if there are extremes its nothing to do with carbon dioxide in the atmosphere its not permanent and its not caused by us.

Global warming is the unusually rapid increase in Earths average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels. 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. QA International 2010.

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. Created and produced by QA International. A long-term change in the Earths climate or of a region on Earth.

The increase in Earths average surface temperature due to rising levels of greenhouse gases. NASAs Global Climate Change website hosts an extensive collection of global warming resources for media educators weathercasters and public speakers. Ice melting at a faster rate than usual in Greenland Antarctica and the Arctic.

Or it could be a change in a places usual temperature for a month or season. The increase in Earths average surface temperature due to rising levels of greenhouse gases. Global climate change refers to the average long-term changes over the entire Earth.

Global warming became the most popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the US. Climate change is also a change in Earths climate. Climate change is a change in the usual weather found in a place.

These include warming temperatures and changes in precipitation as well as the effects of Earths warming such as. Even the term global warming does not mean anything unless you give it a time scale. This could be a change in how much rain a place usually gets in a year.

As the human population has increased so has the volume of fossil fuels burned. 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. Global warming the phenomenon of increasing average air temperatures near the surface of Earth over the past one to two centuries.

Global warming is a phenomenon of climate change characterized by a general increase in average temperatures of the Earth which modifies the weather balances and ecosystems for a long time. Global warming is nonsense. Browse by topic and by media type including videos social media shareables infographics quizzes and interactives.

The global average surface temperature rose 06 to 09 degrees Celsius 11 to 16 F between 1906 and 2005 and the rate of temperature increase has nearly doubled in the last 50 years. It is directly linked to the increase of greenhouse gases in our atmosphere worsening the greenhouse effect.
