WCRP has three co-sponsors:

WMO logo
WMO is a specialized agency of the United Nations, which is dedicated to international cooperation and coordination on the state and behaviour of the Earth’s atmosphere, its interaction with the land and oceans, the weather and climate it produces, and the resulting distribution of water resources. WMO also hosts the WCRP Secretariat. Find out more on the WMO website.
IOC-UNESCO is the United Nations marine science organization. The purpose of the Commission is to promote international cooperation and to coordinate programmes in research, services and capacity-building, in order to learn more about the nature and resources of the ocean and coastal areas and to apply that knowledge for the improvement of management, sustainable development, the protection of the marine environment, and the decision-making processes of its Member States. Find out more on the IOC-UNESCO website.
ISC logo
ISC was created in 2018 as the result of a merger between the International Council for Science (ICSU) (previously a sponsor of WCRP) and the International Social Science Council (ISSC). It is the only international non-governmental organization bringing together the natural and social sciences and the largest global science organization of its type with a vision to advance science as a global public good. You can find out more on the ISC website.

Implementing Partners and Volunteer Contributors

WCRP funding is provided by its co-sponsors (see above), as well as from the voluntary contributions of certain countries. It enables the Programme to initiate, encourage, and stimulate high-priority climate system research. Our effort is substantially supported by joint sponsorship, matching funds/support and collaborative implementation by key partners who share the scientific interests of the WCRP community.

WCRP works closely with a number of climate research institutions towards achieving the scientific goals identified by the WCRP community, and in organizing and implementing knowledge exchange, international scientific initiatives, workshops, meetings, and summer schools. We thank all these partners for their support.

International Offices

In addition to voluntary contributions to WCRP, we also acknowledge and thank the nations and institutions that host the WCRP Secretariat and international offices.
