Scientific intelligence is key to understanding the facts and challenges of human induced climate change. For CAN, the Intergovernmental Panel on Climate Change (IPCC) is the most authoritative scientific body on these issues, because there is no other body whose methodologies guarantee a scientific quality of any comparable level as the IPCC.
Science is a strong driver for progress in the UNFCCC negotiations.
The First Assessment Report of the IPCC (FAR) previously led to the UN Framework Convention on Climate Change (UN FCCC), the Second Assessment Report (SAR) to the Kyoto Protocol, and the Fourth Assessment Report (AR4) helped to mobilize the public and 120 heads of state on a global scale for COP 15 in Copenhagen, which was expected to produce an important climate treaty. Furthermore, the Fifth Assessment Report (AR5) should now prepare for an effective outcome of COP 21, in Paris.
Based on these experiences, CAN considers the work of the IPCC essential for the UNFCCC and strongly supports the establishment of a Sixth Assessment Report (AR6). Some adjustments stimulated by the lessons learnt during AR5 could further improve the products of the IPCC.
