“The EU-funded Copernicus Climate Change Service (C3S), implemented by ECMWF, has provided new tools to make it easier for users to explore how the climate has been changing and how it could change in the future. They include the Copernicus Interactive Climate Atlas, which enables data from a variety of sources and over various timeframes to be visualised, and Climate Pulse, a tool for climate change images intended mainly for the media. The updates come at a time of unprecedented global temperatures over the last year according to C3S data: the last twelve months have been the world’s warmest on record, and they include the warmest month on record. C3S aims to provide policy-makers, businesses and the general public with climate change information that is useful to them. The next milestone in its development will be the introduction of a new higher-resolution climate reanalysis, ERA6, which is expected to replace ERA5 in 2027.”
