The Intergovernmental Panel on Climate Change (IPCC) determines confidence levels in climate projections through a systematic assessment of evidence and agreement among experts. The fifth assessment report outlines specific methodologies for categorizing projections into low, medium, and high confidence levels. Key factors include the robustness of underlying data, the degree of consensus among climate models, and the quality of scientific evidence. The IPCC's uncertainty guidance note provides detailed insights into these processes.
