The International Commission on Climate (ICCL) is composed of scientists who are committed to fulfilling the objectives of the Commission and the International Association of Meteorology and Atmospheric Sciences [IAMAS], through cooperation with their scientific colleagues. Membership of the ICCL is unpaid and takes three forms: (i) regular members, (ii) officers, and (iii) emeritus members.
The International Commission on Climate (ICCL) was established by the International Association for Meteorology and Atmospheric Physics (IAMAP) (now the International Association for Meteorology and Atmospheric Science, IAMAS) at its plenary session in Seattle on 22 August 1977. The commission was established in response to the increasing research activity into the physical basis of climate and its variability. It was intended that the work of the ICCL should complement the work of the other commissions and that it should also include related areas such as ocean atmosphere coupling and past climatic variations and variability.
