GENEVA, Mar 11 – The Intergovernmental Panel on Climate Change is calling for nominations of experts to act as Coordinating Lead Authors, Lead Authors, or Review Editors for the three key Working Group contributions to IPCC´s Seventh Assessment Report (AR7). This follows the Panel’s agreement on the outlines of the three Working Group contributions during its 62nd Session held in Hangzhou, China.

Hundreds of experts around the world in different scientific domains volunteer their time and expertise to produce the reports of the IPCC. Author teams reflect a range of scientific, technical and socio-economic expertise. Coordinating Lead Authors and Lead Authors are responsible for drafting the different chapters of the Working Group contributions to the AR7 and, with the help of the Review Editors, revising those based on comments submitted during the two rounds of reviews by experts and governments.

“Our priority for the Seventh Assessment Report is to attract the most talented individuals across the whole spectrum of scientific, technical and socio-economic research. We would like to see balanced author teams involving both established experts and younger scientists new to the IPCC. It is essential that we reflect fully the breadth and depth of knowledge on climate change and climate action” said IPCC Chair Jim Skea.

IPCC author teams include a mix of experts from different regions to ensure geographic balance. The IPCC also seeks a balance in gender, as well as between those experienced with working on IPCC reports and those new to the process, including younger scientists.

During the 60th Session of the IPCC in January 2024, the Panel agreed to continue to prepare a comprehensive assessment report and to maintain the current Working Group structure where Working Group I assesses the scientific aspects of the climate system and climate change; Working Group II looks at impacts, adaptation, and vulnerability to climate change, and Working Group III assesses the mitigation of climate change.

The outlines of the three Working Group contributions to the AR7 were developed after a comprehensive scientific scoping meeting in December 2024 in Kuala Lumpur, Malaysia before the Panel considered them and agreed upon them at the end of February.

Those interested in being nominated as a Coordinating Lead Author, a Lead Author or a Review Editor should contact their relevant Focal Point. A list of Focal Points for IPCC member governments and observer organizations is available here.

Nominations are submitted through a dedicated online nomination tool by Focal Points in governments and accredited observer organizations, as well as IPCC Bureau Members.

Governments, Observer Organisations, and IPCC Bureau Members have been requested to submit their nominations by Thursday 17 April 2025 (midnight CEST).

More information on the nomination process is here and how the IPCC selects its authors is available here.

Notes for Editors

What is the IPCC?

The Intergovernmental Panel on Climate Change (IPCC) is the UN body for assessing the science related to climate change. It was established by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO) in 1988 to provide political leaders with periodic scientific assessments concerning climate change, its implications and risks, as well as to put forward adaptation and mitigation strategies. In the same year the UN General Assembly endorsed the action by the WMO and UNEP in jointly establishing the IPCC. It has 195 member states.

Thousands of people from all over the world contribute to the work of the IPCC. For the assessment reports, scientists and experts volunteer their time as IPCC authors to assess the thousands of scientific papers published each year to provide a comprehensive summary of what is known about the drivers of climate change, its impacts and future risks, and how adaptation and mitigation can reduce those risks.

The IPCC has three working groups: Working Group I, dealing with the physical science basis of climate change; Working Group II, dealing with impacts, adaptation and vulnerability; and Working Group III, dealing with the mitigation of climate change. It also has a Task Force on National Greenhouse Gas Inventories that develops methodologies for measuring emissions and removals.

IPCC assessments provide governments, at all levels, with scientific information that they can use to develop climate policies. IPCC assessments are a key input into the international negotiations to tackle climate change. IPCC reports are drafted and reviewed in several stages, thus guaranteeing objectivity and transparency.

About the Seventh Assessment Cycle

Comprehensive scientific assessment reports are published every 5 to 7 years. The IPCC is currently in its seventh assessment cycle, which formally began in July 2023 with the elections of the new IPCC and Task Force Bureaus at the IPCC’s Plenary Session in Nairobi. 

At its first Plenary Session in the seventh assessment cycle – the 60th Plenary Session in Istanbul, Türkiye, in January 2024 – the Panel agreed to produce in this cycle the three Working Group contributions to the Seventh Assessment Report (AR7), namely the Working Group I report on the Physical Science Basis, the Working Group II report on Impacts, Adaptation and Vulnerability and the Working Group III report on Mitigation of Climate Change. The Synthesis Report of the Seventh Assessment Report will be produced after the completion of the Working Group reports and released by late 2029.

During its 62nd Plenary Session held in Hangzhou, China, in February 2025, the Panel has agreed on the outlines of the three Working Group contributions to the Seventh Assessment Report (AR7).

The Panel decided already during the previous cycle to produce a Special Report on Climate Change and Cities and a Methodology Report on Short-lived Climate Forcers during AR7.. Scientists have also been asked to deliver a Methodology Report on Carbon Dioxide Removal Technologies, Carbon Capture Utilization and Storage.

At the IPCC’s  61st Plenary Session held in Sofia, Bulgaria, from 27 July to 2 August 2024, the Panel agreed upon the outlines for the Special Report on Climate Change and Cities scheduled for approval and publication in March 2027 and for the 2027 IPCC Methodology Report on Inventories for Short-lived Climate Forcers scheduled for publication in the second half 2027.

In addition, a revision of the 1994 IPCC Technical Guidelines on impacts and adaptation as well as adaptation indicators, metrics and guidelines, will be developed in conjunction with the Working Group II report and published as a separate product.

IPCC’s latest report, the Sixth Assessment Report, was completed in March 2023 with the release of its Synthesis Report, which provided direct scientific input to the First Global Stocktake process under the United Nations Framework Convention on Climate Change at COP28 in Dubai.

The Sixth Assessment Report comprises three Working Group contributions and a Synthesis Report. The Working Group I contribution Climate Change 2021: the Physical Science Basis was released on 9 August 2021. The Working Group II contribution, Climate Change 2022: Impacts, Adaptation and Vulnerability, was released on 28 February 2022. The Working Group III contribution, Climate Change 2022: Mitigation of Climate Change, was released on 4 April 2022 and the Synthesis Report on 20 March 2023. The Synthesis Report to the Sixth Assessment Report, distils and integrates the findings of the three Working Group assessments as well as the three Special Reports released in 2018 and 2019.

The special reports were on Global Warming of 1.5°C (October 2018.), Climate Change and Land (August 2019) and, the Ocean and Cryosphere in a Changing Climate (September 2019).

OSAKA, Japan, Mar 10 – The First Lead Author Meeting of the Intergovernmental Panel on Climate Change (IPCC) Special Report on Climate Change and Cities taking place in Osaka, Japan, from 10 to 14 March 2025, will bring together almost 100 selected experts from more than 50 countries.

The meeting, hosted at the Osaka International Convention Centre by the Ministry of Environment of Japan, will bring together experts with backgrounds in physical science, impacts, adaptation, vulnerability, and mitigation, including researchers and practitioners from urban communities designated to serve as Coordinating Lead Authors and Lead Authors on the report, who have been selected by the scientific bureaus of the three Working Groups.

“The IPCC Special Report on Climate Change and Cities will provide a foundation for all of us to harness the full potential of our cities in tackling climate change, ensuring that they are resilient, inclusive and sustainable for generations to come. We look forward to the insights that our invited experts will bring to developing a robust and actionable report,” said Winston Chow, Co-Chair of Working Group II.

The meeting marks the beginning of the drafting process for this Special Report, which is the only Special Report of the seventh assessment cycle and is scheduled to be finalized in March 2027. Selected authors will work on developing the report based on the outline agreed by the Panel during its 61st Session held in Sofia, Bulgaria from 27 July to 2 August 2024. In this lead author meeting, authors will discuss the literature to be assessed in the report, and how the different chapters will complement each other.

The Special Report on Climate Change and Cities will provide a timely assessment of the latest science related to climate change and cities, including climate impacts and risks, as well as adaptation and mitigation solutions.

“It is exciting to meet the leading experts selected from all corners of the world and diverse fields who come together to draft this Special Report. We applaud the commitment of the scientists and practitioners who volunteer their time and work towards a more liveable future of our cities.” said Diana Ürge-Vorsatz, Chair of the Scientific Steering Committee for the scoping of the Special Report and Vice Chair of the IPCC.

HANGZHOU, Mar 01 – The Intergovernmental Panel on Climate Change has agreed on the outlines of the three Working Group contributions to the Seventh Assessment Report (AR7) during its 62nd Plenary session, which concluded today in Hangzhou, China.

The Panel also approved IPCC’s overall budget for 2025.

“Despite the heavy agenda, thanks to the Panel’s ability to build and achieve multilateral consensus, and the tireless work of the IPCC’s scientific Bureau, we now have clarity on the scope of the scientific content. This allows us to put together author teams and kick start our work on the Seventh Assessment Report.” said IPCC Chair Jim Skea.

From here, governments, observer organisations and IPCC Bureau members will nominate experts to serve as authors.

The Panel’s agreement concludes the initial phase of defining critically important scientific content for the Seventh Assessment Report.

The three Working Group contributions assess the physical science basis of climate change; impacts, adaptation and vulnerability; and mitigation of climate change.

The Panel will consider the outline of the Synthesis Report – the fourth and final instalment of the Seventh Assessment Report – at a later date. The Synthesis Report will integrate the contributions of the three Working Groups and the Special Report produced during the seventh cycle. It will be released in the second half of 2029 in line with the Panel’s decision from January 2024.

Check Against Delivery

Ladies and gentlemen, distinguished delegates, excellencies, dear hosts,

As Chair of the IPCC – allow me first to welcome government delegations, representatives of observer organizations, and IPCC Bureau members attending the Panel’s 62nd Plenary Session.

I also take this opportunity to welcome the staff of the IPCC Secretariat and the Technical Support Units as well as media representatives joining us for the opening ceremony.

I am pleased to greet our dear colleagues and friends. We are honoured that China’s Special Envoy for Climate Change Liu Zhenmin, Administrator of the China Meteorological Administration Chen Zhenlin and Li Yanyi, Vice Governor from Zhejiang Province, will address our opening ceremony this morning.

We will also see recorded video messages from the Executive Director of the United Nations Environment Programme, Inger Andersen, and the Executive Secretary of the UN Framework Convention on Climate Change, Simon Stiell. I am particularly delighted that our former Vice-Chair and the current Deputy Secretary-General of the World Meteorological Organisation Ko Barret is with us for the duration of this plenary.

I also wish to express our special gratitude to the government of China, the authorities of the Zhejiang province and the City of Hangzhou for their warm welcome, exceptional setting and exemplary support and facilitation of this critically important Panel session. We are genuinely impressed by the outstanding organisation of this Plenary. Our hosts have spared no effort to ensure the best possible working environment and conditions for the Panel to deliver in an efficient and timely manner the ambitious programme of work planned for this session.

Since the start of this seventh assessment cycle just 18 months ago, we have made important and steady progress. Six months ago, the Panel gave the green light to the outlines of the Special Report on Climate Change and Cities, and the Methodology Report on Short-Lived Climate Forcers, opening up the process for nominating and selecting authors. With selected authors on board, the first Lead Author Meetings for both reports will take place next month.

Now turning to the impacts of IPCC’s work, it is evident that our timely, policy-relevant and actionable assessment reports have never been more pertinent. Our relevance for policymakers was manifestly reaffirmed and acknowledged in the key decisions of COP29 in Baku.

Specifically – in decisions on the new collective quantified goal on climate finance and UAE Dialogue on the implementation of the Global Stocktake, there were prominent references to the findings from the IPCC Sixth Assessment Report.

The Decision on the Global Goal on Adaptation welcomed IPCC’s own decision to revise and update the 1994 Technical Guidelines for Assessing Climate Change Impacts and Adaptations and invited the IPCC to organise a special event at the next session of Subsidiary Bodies in June this year.

Lastly, I would like to highlight the COP29 decision on Research and Systematic Observation which noted with appreciation, and welcomed, the statements delivered by the IPCC and welcomed the ongoing work of the IPCC in the seventh assessment cycle.

This week we have a rich and demanding agenda to cover. It is a pivotal session for the cycle, and we will be focused on the science.  We will be agreeing outlines of the three Working Group contributions to the Seventh Assessment Report. The Bureau and selected scientists who met at the Scoping Meeting for the Seventh Assessment Report in Kuala Lumpur in December have done their utmost to bring scientifically strong and well-structured drafts to this plenary.

We will also consider the draft outline of the Methodology Report on Carbon Dioxide Removal Technologies, and Carbon Capture Utilization and Storage, a report scheduled for release in 2027.

I’d like to finish by acknowledging the strong and steady support that IPCC member countries have demonstrated in sustaining every aspect of our work. Both support for the science that powers our assessments and generous voluntary contributions. Government support ensures the scientific integrity and continuity of the IPCC as the most authoritative and policy-relevant voice on climate science globally.  

Thank you.

What is the IPCC?

The Intergovernmental Panel on Climate Change (IPCC) is the UN body for assessing the science related to climate change. It was established by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO) in 1988 to provide political leaders with periodic scientific assessments concerning climate change, its implications and risks, as well as to put forward adaptation and mitigation strategies. In the same year the UN General Assembly endorsed the action by the WMO and UNEP in jointly establishing the IPCC. It has 195 member states.

Thousands of people from all over the world contribute to the work of the IPCC. For the assessment reports, scientists and experts volunteer their time as IPCC authors to assess the thousands of scientific papers published each year to provide a comprehensive summary of what is known about the drivers of climate change, its impacts and future risks, and how adaptation and mitigation can reduce those risks.

The IPCC has three working groups: Working Group I, dealing with the physical science basis of climate change; Working Group II, dealing with impacts, adaptation and vulnerability; and Working Group III, dealing with the mitigation of climate change. It also has a Task Force on National Greenhouse Gas Inventories that develops methodologies for measuring emissions and removals.

IPCC assessments provide governments, at all levels, with scientific information that they can use to develop climate policies. IPCC assessments are a key input into the international negotiations to tackle climate change. IPCC reports are drafted and reviewed in several stages, thus guaranteeing objectivity and transparency.

About the Seventh Assessment Cycle

Comprehensive scientific assessment reports are published every 5 to 7 years. The IPCC is currently in its seventh assessment cycle, which formally began in July 2023 with the elections of the new IPCC and Task Force Bureaus at the IPCC’s Plenary Session in Nairobi. 

At its first Plenary Session in the seventh assessment cycle – the 60th Plenary Session in Istanbul, Türkiye, in January 2024 – the Panel agreed to produce in this cycle the three Working Group contributions to the Seventh Assessment Report (AR7), namely the Working Group I report on the Physical Science Basis, the Working Group II report on Impacts, Adaptation and Vulnerability and the Working Group III report on Mitigation of Climate Change. The Synthesis Report of the Seventh Assessment Report will be produced after the completion of the Working Group reports and released by late 2029.

The Panel decided already during the previous cycle to produce a Special Report on Climate Change and Cities and a Methodology Report on Short-lived Climate Forcers during AR7.. Scientists have also been asked to deliver a Methodology Report on Carbon Dioxide Removal Technologies, Carbon Capture Utilization and Storage. At the IPCC’s  61st Plenary Session held in Sofia, Bulgaria, from 27 July to 2 August 2024, the Panel agreed upon the outlines for the Special Report on Climate Change and Cities scheduled for approval and publication in March 2027 and for the 2027 IPCC Methodology Report on Inventories for Short-lived Climate Forcers scheduled for publication in the second half 2027.

In addition, a revision of the 1994 IPCC Technical Guidelines on impacts and adaptation as well as adaptation indicators, metrics and guidelines, will be developed in conjunction with the Working Group II report and published as a separate product.

IPCC’s latest report, the Sixth Assessment Report, was completed in March 2023 with the release of its Synthesis Report, which provided direct scientific input to the First Global Stocktake process under the United Nations Framework Convention on Climate Change at COP28 in Dubai.

The Sixth Assessment Report comprises three Working Group contributions and a Synthesis Report. The Working Group I contribution Climate Change 2021: the Physical Science Basis was released on 9 August 2021. The Working Group II contribution, Climate Change 2022: Impacts, Adaptation and Vulnerability, was released on 28 February 2022. The Working Group III contribution, Climate Change 2022: Mitigation of Climate Change, was released on 4 April 2022 and the Synthesis Report on 20 March 2023. The Synthesis Report to the Sixth Assessment Report, distils and integrates the findings of the three Working Group assessments as well as the three Special Reports released in 2018 and 2019.

The special reports were on Global Warming of 1.5°C (October 2018.), Climate Change and Land (August 2019) and, the Ocean and Cryosphere in a Changing Climate (September 2019).

GENEVA, Feb 03 – The Intergovernmental Panel on Climate Change (IPCC) has selected 97 experts from 56 countries to participate in preparing the Special Report on Climate Change and Cities as Coordinating Lead Authors, Lead Authors and Review Editors.

This marks the beginning of the drafting process for this Special Report, which will be the first report delivered by the IPCC in the seventh assessment cycle. Its release is scheduled for March 2027. Selected authors and review editors will work on developing the report based on the outline agreed by the Panel during its 61st Session held in Sofia, Bulgaria from 27 July to 2 August 2024.

The Special Report on Climate Change and Cities will provide a timely assessment of the latest science related to climate change and cities, including climate impacts and risks, as well as adaptation and mitigation solutions that can be taken to minimize them. Today, more than half of the world’s population is already living in urban areas, a proportion that is expected to further increase by 2050.

“The IPCC Special Report on Climate Change and Cities is a call to action for all of us to harness the full potential of our cities in tackling climate change, ensuring that they are resilient, inclusive and sustainable for generations to come. We look forward to the insights that our chosen experts will bring to develop a robust and actionable report,” said Winston Chow, Co-Chair of Working Group II.

The Bureau Members of all three IPCC Working Groups carefully considered all nominations and developed the final list of authors and review editors. The selection was undertaken according to the Principles Governing IPCC Work, which has considered the required scientific, technical and socio-economic expertise, geographical and gender balance, and the inclusion of experts with and without previous IPCC experience.

“The selection of the authors for this Special Report is an important step in its production, a leap from the Panel’s decision nine years ago to include it in the IPCC’s seventh assessment cycle.

We are inspired by the strong support from the scientific community worldwide wanting to contribute to this IPCC Special Report, as evidenced by the large number of nominations for Lead Authors and Review Editors, and also by the growing body of scientific literature and interest surrounding climate change and cities,” said Joy Pereira, Co-Chair of Working Group III.

The 97 experts that will undertake the assessment were selected from 1,201 nominations submitted by IPCC’s national focal points and observer organizations. Of the selected experts, 53 per cent are women and 54.6 per cent come from developing countries and economies in transition. Nearly a third are new to the IPCC process.

The overall number of nominations confirms a robust and growing interest of the global scientific community in support for the IPCC and its work. Interested experts can contribute as an Expert Reviewer during the review of this Special Report. Another call will be launched for experts to register for the Expert Review of the First Order Draft of the Special Report on Climate Change and Cities that will take place in the second half of 2025.

Notes for Editors

What is the IPCC?

The Intergovernmental Panel on Climate Change (IPCC) is the UN body for assessing the science related to climate change. It was established by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO) in 1988 to provide political leaders with periodic scientific assessments concerning climate change, its implications and risks, as well as to put forward adaptation and mitigation strategies. In the same year the UN General Assembly endorsed the action by the WMO and UNEP in jointly establishing the IPCC. It has 195 member states.

Thousands of people from all over the world contribute to the work of the IPCC. For the assessment reports, experts volunteer their time as IPCC authors to assess the thousands of scientific papers published each year to provide a comprehensive summary of what is known about the drivers of climate change, its impacts and future risks, and how adaptation and mitigation can reduce those risks.

The IPCC has three working groups: Working Group I, dealing with the physical science basis of climate change; Working Group II, dealing with impacts, adaptation and vulnerability; and Working Group III, dealing with the mitigation of climate change. It also has a Task Force on National Greenhouse Gas Inventories that develops methodologies for measuring emissions and removals.

IPCC assessments provide governments, at all levels, with scientific information that they can use to develop climate policies. IPCC assessments are a key input into the international negotiations to tackle climate change. IPCC reports are drafted and reviewed in several stages, thus guaranteeing objectivity and transparency.

About the Seventh Assessment Cycle

Comprehensive scientific assessment reports are published every 5 to 7 years. The IPCC is currently in its seventh assessment cycle, which formally began in July 2023 with the elections of the new IPCC and Taskforce Bureaus at the IPCC’s Plenary Session in Nairobi. 

IPCC’s latest report, the Sixth Assessment Report, was completed in March 2023 with the release of its Synthesis Report, which provides direct scientific input to the first global stocktake process under the United Nations Framework Convention on Climate Change at COP28 in Dubai.

The Sixth Assessment Report comprises three Working Group contributions and a Synthesis Report. The Working Group I contribution Climate Change 2021: the Physical Science Basis was released on 9 August 2021. The Working Group II contribution, Climate Change 2022: Impacts, Adaptation and Vulnerability, was released on 28 February 2022. The Working Group III contribution, Climate Change 2022: Mitigation of Climate Change, was released on 4 April 2022 and the Synthesis Report on 20 March 2023. The Synthesis Report to the Sixth Assessment Report, distills and integrates the findings of the three Working Group assessments as well as the three Special Reports released in 2018 and 2019.

The special reports were on Global Warming of 1.5°C (October 2018.), Climate Change and Land (August 2019) and, the ocean and cryosphere in a changing climate (September 2019).
