State of the Climate in Latin America and the Caribbean 2020 represents the first multi-agency effort involving National Meteorological and Hydrological Services (NMHSs), WMO Regional Climate Centres (RCCs), research institutions, and international and regional organizations. A multidisciplinary group of 40 experts developed and reviewed this report through an interactive process coordinated by the WMO Offices for Regional Association III and Regional Association IV. This report provides a snapshot of climate trends, variability, observed high-impact weather and climate events, and associated risks and impacts in key sensitive sectors for the period January–December 2020. It is the result of a collaboration among countries, presenting information from various independent sources to assess weather, hydrology and climate conditions in the region. It includes transboundary analyses, including of the drought in the South American Pantanal and of the intense hurricane season in Central America and the Caribbean and associated impacts. In addition, the report identifies areas for improvement in the management of hydrometeorological risks and data, and knowledge gaps.
