a definition for global warming
global warming - an increase in the average temperature of the earth's atmosphere (especially a sustained increase that causes climatic changes) heating, warming - the process of becoming warmer; a rising temperature. an increase in the earth's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. global warming. An increase in the average temperature of the Earth's atmosphere, especially a sustained increase great enough to cause changes in the global climate. Many scientists believe that the Earth has been in a period of global warming for the past century or more, due in part to the increased production of greenhouse gases related to human activity. See more at greenhouse effect. Definition of Global Warming: A gradual increase in the earth’s average surface temperature. Technical term for this: Anthropogenic global warming. Definition of Greenhouse Gas: A gas, like CO2, which traps the sun’s heat. global warming - an increase in the average temperature of the earth's atmosphere (especially a sustained increase that causes climatic changes) heating, warming - the process of becoming warmer; a rising temperature. Earth and environmental scientists explore some of the ways that climate warming since the Last Glacial Maximum, some 20,000 years ago, has triggered geological events, primarily because of the shift in weight on the lithosphere as stationary glaciers melt and become moving oceans. Many scientists believe that the Earth has been in a period of global warming for the past century or more, due in part to the increased production of greenhouse gases related to human activity. See more at greenhouse effect. Global warming and climate change are terms for the observed century-scale rise in the average temperature of the Earth's climate system and its related effects. Multiple lines of scientific evidence show that the climate system is warming. Although the increase of near-surface atmospheric temperature is the measure of global warming often reported in the popular press, most of the additional energy stored in the climate system since 1970 has gone into the oceans. Common-usage definition: Warming caused by human activity. Technical term for this: Anthropogenic global warming. Definition of Greenhouse Gas: A gas, like CO2, which traps the sun’s heat. Definition of Global Carbon Pricing: A single price per ton of CO2 that all countries would try to achieve. This page is about the current warming of the Earth's climate system. Climate change can also refer to climate trends at any point in Earth's history. For other uses see Global warming (disambiguation) Global mean surface temperature change from 1880 to 2015, relative to the 1951–1980 mean.
