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).

Some archived end-of-year graphs are based on the earlier (now superseded) versions.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.
