The IPCC organizes a number of meetings with different objectives and level of participation. They include Plenary sessions of the IPCC and IPCC Working Groups which are attended by representatives from governments and participating organizations, sessions of the IPCC Bureau, the Task Force Bureau and any task group set up by the Panel, as well as workshops, scoping and other expert meetings, and meetings of lead authors involved in preparing an IPCC report. The IPCC co-sponsors also meetings to support the assessment process, to disseminate its results and enhance interaction with scientists and users.
