Climate knowledge is the foundation for the development of an effective response to the climate change challenge. The UN system plays a central role in this area, bringing together global resources for observation and analysis of climate change trends. It is committed to reinforcing its efforts to provide sound and unbiased scientific information and climate services to enable evidence-based policy and decision making at all levels.

Building up the individual and collective capacity of countries to monitor climate change, enhance climate science and services and utilize climate predictions is crucial for effective adaptation and mitigation strategies. Such capacity also enables timely planning to reduce the impact of increasing natural disasters, enhance food security and manage climate risks in all socioeconomic sectors.

IPCC, co-sponsored by WMO and UNEP and supported by other UN system agencies, has during its two decades of existence provided the authoritative scientific evidence that underpins all action in response to climate change.
