Since 1989, advocates have clashed on the issue of whether human beings are more responsible than nature for  modern periods of global warming; see "[[greenhouse warming]]" and [[global warming theory]].<ref>Some people predicted "global warming," which has come to mean extreme [[greenhouse warming]] of the atmosphere leading to catastrophic environmental consequences.

In the public perception support for the global warming theory rests on popular accounts such as Al Gore's ''[[An Inconvenient Truth]]'' or on reports issued by the UN's [[IPCC]].  

Most non-scientific support for the global warming theory rests on popular accounts such as Al Gore's ''[[An Inconvenient Truth]]'' or on reports issued by the UN's [[IPCC]]. However, Keston Green of Monash University and Scott Armstrong of the Wharton School wrote that:

However, it is to be noted that many proponents of the theory propose energy conservation only until 'green' energy generation becomes predominant.{{Fact}}

In the general, the term ''global warming'' can be used for any upward trend in the [[global mean temperature]], but it is mostly used to refer to the 1° F warming since 1850.
