Question

Why does climate change need an
international response?

Answer 1

The ultimate aim of the UNFCCC is to stabilise greenhouse gas concentrations at a level that prevents dangerous human interference with the climate system. The Convention believes that such a level should be achieved: within a timeframe sufficient to allow ecosystems to adapt naturally to climate change.
