The Definition of Globalย Warming:

There are various definitions available for global warming, here are a few that we think are particularlyย good.

Fromย Wikipedia:

Global warming is the increase in the average temperature of the Earthโ€™s near-surface air and the oceans since the mid-twentieth century and its projected continuation. Global surface temperature increased 0.74 ยฑ 0.18ย ยฐC (1.33 ยฑ 0.32ย ยฐF) during the 100 years ending inย 2005.

The Intergovernmental Panel on Climate Change (IPCC) concludes that anthropogenic greenhouse gases are responsible for most of the observed temperature increase since the middle of the twentieth century, and that natural phenomena such as solar variation and volcanoes probably had a small warming effect from pre-industrial times to 1950 and a small cooling effect afterward. These basic conclusions have been endorsed by more than 40 scientific societies and academies of science, including all of the national academies of science of the major industrializedย countries.


From the Encylopdia ofย Earth:

The phrase global warming refers to the documented historical warming of the Earthโ€™s surface based upon worldwide temperature records that have been maintained by humans since theย 1880s.

The term global warming is often used synonymously with the term climate change, but the two terms have distinct meanings. Global warming is the combined result of anthropogenic (human-caused) emissions of greenhouse gases and changes in solar irradiance, while climate change refers to any change in the state of the climate that can be identified by changes in the average and/or the variability of its properties (e.g., temperature, precipitation), and that persists for an extended period, typically decades orย longer.
