Professor Alessandro Tagliabue, from the University of Liverpool's School of Environmental Sciences, has been appointed a Coordinating Lead Author for the Seventh Assessment Report (AR7) of the Intergovernmental Panel on Climate Change (IPCC).
Professor Tagliabue is an ocean biogeochemist whose research focuses on the processes that shape ocean biogeochemical cycles and their influence on marine biological activity.
This appointment places him among a select group of international experts responsible for leading the scientific assessment that will inform governments around the world about the latest evidence on climate change.
As a Coordinating Lead Author, Professor Tagliabue will co-lead Chapter 4: Advances in Process Understanding of Earth System Changes, overseeing a team of Lead Authors from across the globe.
He will be responsible for ensuring the chapter reflects the latest scientific evidence, incorporates a broad range of international expertise and perspectives, and meets the IPCC's rigorous standards for quality and scientific accuracy.
In addition, Professor Tagliabue will contribute to drafting AR7's Summary for Policymakers and take part in the government review process that helps to finalise one of the world's most influential climate science publications.
Professor Tagliabue took up his new role in June 2026 and AR7 is expected to be published in 2029.
Commenting on his new role, Professor Alessandro Tagliabue said: "I am honoured to have been appointed as a Coordinating Lead Author for Chapter 4 of the Seventh Assessment Report.
"The IPCC plays a critical role in bringing together the best available scientific evidence on climate change and providing governments with the information and data they need to make informed decisions.
"This role provides a unique opportunity to work alongside leading researchers from around the world to assess the latest science on climate impacts, adaptation and resilience.
"I look forward to contributing my expertise and helping ensure the report provides a robust, balanced and policy-relevant assessment that can support effective climate action globally."
Professor Tagliabue has previously served as a Lead Author for the IPCC's Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC), which was published in 2019.
Established in 1988 by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP), the IPCC is the United Nations body responsible for assessing the science of climate change.
