GHRSST Task teams are set up to address particular issues identified by the GHRSST Science Team. Task teams (TTs) are proposed and agreed at the annual Science Team Meetings (STM). Each task team has a chair and a team of volunteers, the task team members. Each chair is asked to appoint an early-career scientist as co-chair to encourage participation in GHRSST and ensure continuation of knowledge.

The task teams report their findings at the annual Science Team Meetings and the Science Team decides if the task team has completed its task or should continue.

The list below gives the current working task teams.
