ESOTC 2023

European State of the Climate 2023

The 2023 ESOTC report provides descriptions and analysis of climate conditions and variations from across the Earth system. This year, in addition to examining key events and their impacts, it also discusses climate policy and action, with a focus on human health. The 2023 edition is produced jointly with the World Meteorological Organization (WMO) for the first time.

Copernicus Polar Roadmap: C3S and CAMS data support Arctic policymaking

The launch in September 2024 of the Copernicus Polar Roadmap marks a significant step in the EU’s efforts to enhance Earth observation in the polar regions.
September climate bulletin

Second warmest September globally and in Europe

September 2024 was the second-warmest September globally in the ERA5 dataset, after September 2023, with an average surface air temperature of 16.17°C. Last month was 0.73°C above the 1991-2020 average for September.

Shape the Future of Climate and Atmosphere Monitoring

CAMS and C3S, both implemented by ECMWF, provide crucial data on air quality, the Earth’s changing climate, and more. We are eager to learn more about how these data products and services are being used, and by whom.

Data rescue in Africa

The process of data rescue involves converting historical data into a consistent modern format. By making these data open access they are available to researchers, who thus have a wealth of information to inform and guide policymakers.

Climate Analogues – finding tomorrow's climate today

With Climate Analogues, users can look at the potential future climate of a selected location. The application presents three other locations and their respective climates, each of which has a current climate that could match the future climate of the selected location.
All case studies

Data from the Copernicus Climate Change Service show that Europe had its warmest summer on record. The period from June to August was the warmest ever on a global scale, with temperatures 0.7 degrees Celsius above the 1991-2020 average. The summer period was wetter than average in western and northern Europe, and drier than average in eastern Europe and the Mediterranean.

In this episode of Climate Now we ask how the Alps are changing as temperatures rise.
