The 165 page, peer-reviewed journal article was commissioned by the World Climate Research Programme (WCRP) and included input from Professor Piers Forster, Director of the Priestley International Centre for Climate at Leeds and Principal Investigator of the CONSTRAIN consortium, as well as other CONSTRAIN members.

The work was led by University of New South Wales.

For more than 40 years, the estimated likely range of the eventual global temperature response to a doubling of atmospheric carbon dioxide compared to preindustrial levels has stubbornly remained at 1.5°C – 4.5°C.
