Professor Alessandro Tagliabue, from the School of Environmental Sciences at the University of Liverpool, was appointed coordinating lead author of the Seventh Assessment Report (AR7) of the Intergovernmental Panel on Climate Change (IPCC).
Professor Tagliabue is an oceanic biogeochemist whose research focuses on the processes that shape oceanic biogeochemical cycles and their influence on marine biological activity.
This appointment places him among a small 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 the coordinating lead author, Professor Tagliabue will co-direct Chapter 4: Progress in Understanding the Processes of Earth System Changes, overseeing a team of lead authors from around the world.
He will be responsible for ensuring that the chapter reflects the latest scientific evidence, integrates a wide 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 the writing of the AR7 summary for decision-makers and participate in the government review process that helps finalize one of the most influential climate publications in the world.
Professor Tagliabue took up his new duties in June 2026 and AR7 is expected to be published in 2029.
Commenting on his new role, Professor Alessandro Tagliabue said: « I am honored to have been appointed coordinating lead author for chapter 4 of the seventh evaluation report.
“The IPCC plays a crucial role in gathering the best available scientific evidence on climate change and providing governments with the information and data necessary to make informed decisions.
“This role offers a unique opportunity to work alongside leading researchers from around the world to assess the latest scientific advances on climate impacts, adaptation and resilience.
“I look forward to contributing to my expertise and helping to ensure that the report provides a robust, balanced and relevant assessment for public policy, capable of supporting effective global climate action. «
Professor Tagliabue was previously the lead author of the IPCC Special Report on the Ocean and the Cryosphere in a Changing Climate (SROCC), published in 2019.
Created in 1988 by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP), the IPCC is the United Nations body responsible for evaluating the science of climate change.
