At the Earth Summit in Rio de Janeiro in 1992, the world’s nations signed up to the Framework Convention on Climate Change (FCCC), the objective of which is “to stabilize the concentration of greenhouse gases in the atmosphere at a level that does not cause dangerous interference with the climate system…, that allows ecosystems to adapt naturally to climate change, that ensures food production is not threatened, and that enables economic development to proceed in a sustainable manner.” Such stabilization would also eventually stop further climate change.
