Global Warming 2020

 Global Warming Definition from Google Search : What is Global Warming

• an increase of the earth’s temperature by a few degrees resulting in an increase in the volume of water which contributes to sea-level rise
  www.nwrc.usgs.gov/fringe/glossary.html

• increase in the average temperature of the earth’s surface.
  www.nrdc.org/reference/glossary/g.asp

• An increase in the near surface temperature of the Earth. Global warming has occurred in the distant past as the result of natural influences, but the term is most often used to refer to the warming predicted to occur as a result of increased emissions of greenhouse gases.

• (See GREENHOUSE EFFECT, CLIMATE)

• Strictly speaking, global warming and global cooling refer to the natural warming and cooling trends that the earth has experienced all through its history. …

• A gradual warming of the Earth’s atmosphere reportedly caused by the burning of fossil fuels and industrial pollutants.
  www.wisconsinpublicservice.com/farm/terms.asp

• A rise in the temperature of the Earth’s atmosphere due to the increase in certain gases in the atmosphere
  www.eon-uk.com/EnergyExperience/110.htm

• The warming of the lower atmosphere due to the increased emission of greenhouse gases.
  www.ac.wwu.edu/~gisele/glossary.html

• An overall increase in world temperatures which may be caused by additional heat being trapped by greenhouse gases.
  www.srh.noaa.gov/jetstream/append/glossary_g.htm

• An increase in the Earth’s temperature caused by human activities, such as burning coal, oil and natural gas. This releases carbon dioxide, methane, and other greenhouse gases into the atmosphere. …
  www.pca.state.mn.us/gloss/glossary.cfm

• The view that the earth’s temperature is being increased, in part, due to emissions of greenhouse gases associated with human activities such as burning fossil fuels, biomass burning, cow and sheep rearing, deforestation and other land use changes. (see climate change, Kyoto Protocol and UNFCCC)
  www.pce.govt.nz/reports/pce_reports_glossary.shtml

• The earth has warmed up by about 0.6ºC in the last 100 years. During this period, human emissions of greenhouse gases have increased, largely as a result of the burning of fossil fuels and deforestation. …
  www.climatechangenorth.ca/H1_Glossary.html

• Increased levels of gases such as carbon dioxide that trap heat in the earth’s lower atmosphere potentially causing global warming
  www.ifdn.com/teacher/glossary.htm

• Global warming is the phenomenon whereby the average temperature of the Earth is rising due to increases in the amounts of greenhouse gases such as CO 2 in the atmosphere. …
  www.nec.co.jp/eco/en/annual2006/16/g.html

• the measured increase in the aggregate global temperature due to the burning of fossil fuels
  www.globalwarming101.com/content/view/522/

• Changes in the surface-air temperature, referred to as the global temperature, brought about by the greenhouse effect which is induced by emission of greenhouse gases into the air.
  www.dantes.info/Projectinformation/Glossary/Glossary.html

• is the term given to the major consequence of the greenhouse effect. Scientists have long predicted and recently measured notable increases in the world’s temperature. …
  www.travelsmart.gov.au/teachers/teachers7.html

• The gradual heating of the Earth due to greenhouse gases, leading to climate change and rising sea levels. Renewable energy, energy efficient buildings and sustainable travel are examples of ways to help avert the greenhouse effect.
  www.planningportal.gov.uk/

• Certain Gasses such as carbon dioxide, methane, nitrous oxides and chlorofluorocarbons (CFC’s) absorb reflected infra-red radiation and trap it within the earths atmosphere. This heat which would normally be dissipated into space increases the 5temperature of the earth. …
  www.ecifm.rdg.ac.uk/glossary.htm

• The greenhouse effect acts to warm the plant and increase average global temperatures. This is seen as a major environmental hazard as average temperatures rise, leading to a possible change in weather patterns and agricultural output. …
  www.med.uwo.ca/EcoSystemHealth/education/glossary.htm

• the apparent recent trend of increasing world-surface and tropospheric temperatures, thought to be caused by pollutants, and their “entrapment” of heat. This phenomenon is popularly known as “the greenhouse effect.”
  www.rtcc.org/2007/html/glossary.html

• A popular term used to describe the increase in average global temperatures due to the greenhouse effect.
  www.dmme.virginia.gov/DE/glossaryterms.shtml

• An increase in the average temperature of the earth’s atmosphere, especially a sustained increase sufficient to cause climatic change. Most scientists believe that a rise in carbon dioxide levels (caused by automobile, power plant, and other emissions) will lead to further global warming.
  www.hubbardbrook.org/6-12_education/Glossary/Glossary.htm

• heating that occurs when carbon dioxide traps the Sun’s heat near Earth’s surface, causing Earth’s temperature to rise
  www.wcit.org/tradeis/glossary.htm

• the expected consequence of an increase in the concentration of greenhouse gases by human activity (see greenhouse gases).
  www.forest.nsw.gov.au/education/glossary/default.asp

• an increase in the average temperature of the earth’s atmosphere (especially a sustained increase that causes climatic changes)
  wordnet.princeton.edu/perl/webwn

• Global warming is the observed increase in the average temperature of the Earth’s near-surface air and oceans in recent decades and its projected continuation.
