This document discusses enhancing the climate science basis for climate rationale in projects funded by the Green Climate Fund (GCF). It defines climate rationale as providing the evidence for climate investment and policy decision making by assessing the causal links between climate action and climate impacts. The World Meteorological Organization (WMO) is well positioned to successfully deliver work on climate rationale methodology due to its authoritative role in climate science and services. The methodology would utilize climate indicators, datasets and tools to assess the current and projected future state of the climate. Support would be provided to strengthen the capacity of national hydro-meteorological offices and allow for country ownership in using climate science for GCF projects and national adaptation plans.
