|UN Framework Convention on Climate Change|
A treaty signed at the 1992 Rio de Janeiro Earth Summit that called for the "stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system.
1. The treaty took effect in March 1994 upon ratification by more than 50 countries.
2. The treaty was formulated and signed before any scientific evidence of a human fingerprint on global warming had been compiled. This suggests that the goal — reduction of fossil fuel consumption — was more important than any science that would prove that this reduction was necessary.
