IPCC - WGI
Framework Convention on Climate Change (Article 2)
The ultimate objective of this ConventionÉ.is to achieveÉ
stabilization of the greenhouse gas concentrations in the
atmosphere at a level that would prevent dangerous
anthropogenic interference with the climate system.

Such a level should be achieved with a time-frame sufficient
to allow ecosystems to adapt naturally to climate change,
to insure that food production is not threatened, and to
enable economic development to proceed in a sustainable
manner.
