This page contains some visualisations of global and hemispheric temperatures. The temperature dataset used is our HadCRUT5 data (land and marine), or our CRUTEM5 data (land only).

Note that HadCRUT4 and CRUTEM4 have now been superseded by HadCRUT5 and CRUTEM5 and the graphs have been updated to the new versions. Some archived end-of-year graphs are based on the earlier (now superseded) versions.

Click the "more info" links for details about each visualisation, or click the images to obtain a larger image. You are free to use these images provided you attribute them to Tim Osborn (CRU, UEA) and cite the HadCRUT5 or CRUTEM5 references listed below.
