The European State of the Climate (ESOTC) 2021 is the fifth in a series of annual ESOTC reports, typically released in April each year. It is one of the products in the C3S portfolio of climate monitoring services, alongside the monthly Climate Bulletins and the C3S Climate Indicators, which all cover the globe, Europe and the polar regions, but with varying emphasis.
The ESOTC 2021 report includes a short overview of the global context during the year, a more comprehensive overview of conditions in Europe, and a focus on the Arctic. It provides a detailed analysis, with descriptions of climate conditions and events, and explores the associated variations in key climate variables from across all parts of the Earth system. The key findings for each section can be found in the ESOTC Summary. In addition to summarising the ESOTC sections, the Summary also outlines the latest updates of the C3S Climate Indicators.
