WMO statement on the status of the global climate in 2015

As part of its mandate to provide authoritative information about weather, climate and water, the World Meteorological Organization (WMO) conducts annual assessments of the state of the global climate. For over two decades, those assessments have been published in the six official languages of the United Nations in order to inform governments, international agencies and other WMO partners about global climate trends, and extreme and notable weather and climate events at the national and regional levels.
