The Copernicus Interactive Climate Atlas (<a href="http://atlas.climate.copernicus.eu">http://atlas.climate.copernicus.eu</a>, C3S Atlas in short) was released by the Copernicus Climate Change Service (C3S) in early 2024. It is a new C3S application (<a href="https://cds.climate.copernicus.eu/applications">https://cds.climate.copernicus.eu/applications</a>) which enables an interactive exploration of the Earth's climate, from recent changes and trends to possible climate futures under different emission scenarios. It uses key datasets that are available in the C3S Climate Data Store (CDS), including observation-based datasets (E-OBS), reanalyses (ECMWF's ERA5, ERA5-Land and ORAS5), and comprehensive global (CMIP5/6) and regional (CORDEX) climate projections. The goal is to produce authoritative climate change information for a wide range of physical variables. The variables characterise various types of climatic impact-driving conditions (heat and cold, wet and dry, wind and radiation, snow and ice, ocean, circulation) relevant for climate change risk assessments. The C3S Atlas is a new resource for policy makers wishing to formulate effective climate policy and for other users who need to visualise and analyse climate change information, particularly at the regional scale. This C3S tool is an evolution of the Intergovernmental Panel on Climate Change (IPCC) Interactive Atlas (IPCC-IA), which was frozen in 2021 with the publication of the Sixth Assessment Report's (AR6) WGI (Working Group I) section (see <a href="https://www.ipcc.ch/report/ar6/wg1">https://www.ipcc.ch/report/ar6/wg1</a>).</p>
