Climate Services aim at providing more reliable climate information for the near future (months to decades) relevant for local and regional users. Within this broad context, variability of polar and tropical systems affects a large proportion of the world population.

This call aims to contribute to the overall challenge of developing climate services with a focus on inter-regional linkages role in climate variability and predictability. Major impediments indeed still exist having efficient climate services at regional and local level, because of little or poorly understood climate processes (in part caused by a paucity of observations), inadequate dissemination of scientific knowledge, conflicts between climatic and non-climatic stressors and lack of action by decision makers and the human society at large.
