GENEVA, June 19 — The Intergovernmental Panel on Climate Change (IPCC) and the American Geophysical Union (AGU) announce access to the full library of AGU Publications for IPCC authors working on the Panel’s Seventh Assessment Report, or AR7.
“This landmark decision is an invaluable scientific boost for the IPCC’s ongoing work,” said IPCC Chair Jim Skea. “It will enable our authors from developing countries and those facing access barriers to enhance their scientific contributions to the upcoming reports of IPCC’s three Working Groups assessing the latest science related to climate change. We encourage other major scientific publishers to consider following suit at this critical time for climate science.”
As a non-profit scholarly publisher, AGU publishes 24 peer-reviewed high-impact journals and four active book series, including monographs, advanced-level textbooks, and technical manuals across the entire spectrum of Earth and space sciences. It also runs the Earth and Space Science Open Archive.
AGU journals publish research articles, letters, commentaries and other types of scholarly content within the fields of Earth and space sciences. Covering topics ranging from atmospheric science and oceanography to geophysics, planetary science, and climate change, AGU journals are an essential mode of information sharing and enterprise building for the global scientific community.
“IPCC Reports provide authoritative scientific consensus on climate change to a broad spectrum of key players, from government and community leaders to industries and advocacy organizations,” said AGU President Brandon Jones. “Opening AGU publications’ portfolio to the authors of the Seventh Assessment Report provides greater equitable access to critical research of the scientific community, which can be assessed, considered, and weighed when informing the final report.”
Following the Panel’s agreement in February on the outlines of the three Working Group contributions during its 62nd Session held in Hangzhou, China, the IPCC has now completed the call 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.
Hundreds of experts in different scientific domains worldwide will be selected to volunteer their time and expertise to produce the new set of IPCC Reports. Author teams will reflect a range of scientific, technical, and socio-economic knowledge. Coordinating Lead Authors and Lead Authors will be 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.
IPCC author teams include experts from different regions to ensure geographic balance. The IPCC also seeks a balance in gender, as well as a balance between those authors with experience in working on IPCC Reports and those new to the process, including younger scientists.
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.

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.
What is AGU
The American Geophysical Union (www.agu.org) is a global community supporting more than half a million scientists, advocates, and professionals in Earth and space sciences. Through broad and inclusive partnerships, AGU aims to advance discovery and solution science that accelerate knowledge and create solutions that are ethical, unbiased and respectful of communities and their values. Our programs include serving as a scholarly publisher, convening virtual and in-person events and providing career support. We live our values in everything we do, such as our net zero energy renovated building in Washington, D.C. and our Ethics and Equity Center, which fosters a diverse and inclusive geoscience community to ensure responsible conduct.
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).

GENEVA, Mar 24 – Over 100 experts from more than 40 countries are meeting in Bilbao, Spain this week for the first meeting of authors and review editors of the 2027 IPCC Methodology Report on Inventories for Short-lived Climate Forcers (SLCF). This will be the first methodology report released by IPCC in the seventh assessment cycle and it is being prepared by the Task Force on National Greenhouse Gas Inventories (TFI).
The 2027 Methodology Report is expected to provide guidance on anthropogenic emissions for Short-lived Climate Forcers, not including secondary human-induced substances.
“The report aims to provide clear guidance on measuring emissions from key short-lived climate forcing substances, including nitrogen oxides, carbon monoxide, and others, which significantly contribute to global and regional air quality and climate change,” said Takeshi Enoki, one of the Co-Chairs of the TFI.
This week´s meeting in Bilbao marks the beginning of the drafting process of this Methodology Report which is scheduled to be released in March 2027. The Coordinating Lead Authors and Lead Authors at this meeting will start developing the report based on the outline agreed by the Panel during its 61st Session held in Sofia, Bulgaria in July/August 2024.
“We are excited to begin work on this report with a diverse group of experts selected from the 394 nominations we received. Their work will be important for enhancing the data used in climate models,” said Mazhar Hayat, TFI Co-Chair.
Following the Panel’s 61st Session, the IPCC called for nominations of experts to act as Authors and Review Editors of the 2027 Methodology Report in August 2024. The TFI Bureau, also known as the Task Force Bureau, in consultation with relevant Working Group Co-Chairs selected the report’s Coordinating Lead Authors, Lead Authors and Review Editors. In their selection, they considered scientific and technical expertise, geographical and gender balance in line with Appendix A to the Principles Governing IPCC Work.
A preliminary list of the Authors for the 2027 Methodology Report is available here.
Following the Lead Author Meeting, there will be an outreach event hosted by the Spanish Climate Change Office at the Bizkaia Aretoa in Bilbao on 27 March 2025. More details on the event are available here.

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.

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.
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.

HANGZHOU, Feb 24 – The 62nd Plenary Session of the Intergovernmental Panel on Climate Change (IPCC) opened today in Hangzhou, China, to consider and agree on the draft outlines of the three Working Group contributions to the Seventh Assessment Report (AR7) and the Methodology Report on Carbon Dioxide Removal Technologies, Carbon Capture Utilization and Storage.
During the week-long session, the delegates representing Panel’s 195 member governments will also consider the respective timelines and budgets for these four reports.
“This is a pivotal session for the delivery of the IPCC’s Seventh Assessment Report”, said IPCC Chair Jim Skea.
The Panel’s agreement on the outlines of the three Working Group contributions to the Seventh Assessment Report and the Methodology Report on Carbon Dioxide Removal Technologies, Carbon Capture Utilization and Storage as proposed by the scoping meeting participants will clear the way for the scientists to start their work on these four reports.
The meeting’s agenda also includes IPCC program and budget and an early consideration of the AR7 Synthesis Report-the final installment of the Seventh Assessment Report to be finalized by late 2029. No decision about the Synthesis Report is expected at this point.
On behalf of the People’s Republic of China hosting this Plenary, the country’s Special Envoy for Climate Change Liu Zhenmin, and Chen Zhenlin, Administrator of the China Meteorological Administration, welcomed delegates and observer organisations at an opening ceremony at InterContinental Hangzhou in the Zhejiang province.
In addition to the IPCC Chair, more than 400 delegates were also addressed by Ko Barrett the Deputy Secretary General of the World Meteorological Organization. The ceremony also included screening of video messages from Inger Andersen, the Executive Director of the United Nations Environment Programme, and Simon Stiell the Executive Secretary of the United Nations Framework Convention on Climate Change.
Except for the opening session, the IPCC meeting is closed to media.

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.

More than 230 experts from over 70 countries will gather at the Scoping Meeting in Kuala Lumpur, Malaysia from 9 to 13 December to draft the outlines of the three Working Group contributions to the Seventh Assessment Report (AR7) of the Intergovernmental Panel on Climate Change (IPCC).
Working Group contributions are the three key pillars of the IPCC’s periodical assessment reports. They include 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.
“This is the critical first step in shaping the contents of our next report assessing the science related to climate change. In this meeting, experts will consider the scientific substance and draft the overall structure of the three Working Group contributions for governments to consider and agree upon in the Panel’s upcoming Plenary scheduled for February next year,” said IPCC Chair Jim Skea.
The Panel decided to produce its Seventh Assessment Report in January 2024 during its 60th Plenary Session in Istanbul, Türkiye.
The Seventh Assessment Report comprises the three Working Group contributions and a Synthesis Report which the IPCC decided should be ready in 2029. The Synthesis Report, which will draw together findings from the three Working Group contributions and a Special Report on Climate Change and Cities, will be the subject of a further scoping meeting.
The full set of reports assessing the latest climate change science during the seventh assessment cycle includes the Special Report on Climate Change and Cities, a Methodology Report on Short-lived Climate Forcers, a Methodology Report on Carbon Dioxide Removal Technologies, Carbon Capture Utilization and Storage and a revision and an update of the 1994 IPCC Technical Guidelines on Impacts and Adaptation including adaptation indicators, metrics and guidelines. The latter will be developed in conjunction with the Working Group II report and published as a separate product.
The Seventh Assessment Report will assess scientific findings that have been published since the completion of the Sixth Assessment Report in March 2023.
The Sixth Assessment Report clearly stated that in 2020 global warming reached 1.1°C, above pre-industrial level, driven by more than a century of burning fossil fuels as well as unequal and unsustainable energy and land use. This has resulted in more frequent and more intense extreme weather events that have caused increasingly dangerous impacts on nature and people in every region of the world. Impacts are expected to intensify with every fraction of additional warming, particularly for the most vulnerable communities, accounting for 3.3 – 3.6 billion people. This report underlined the urgency of transformative adaptation and immediate emissions reductions. It also noted that there are tools, such as renewable energy, and options across all sectors to limit warming to 1.5°C, but that progress needs to accelerate as the chances of achieving that goal are becoming increasingly thin.
Following the AR7 Scoping Meeting, IPCC Bureau Members will take part in a symposium on bridging climate science and policy to accelerate climate action organised by the government of Malysia, the British High Commission in Malaysia and the Universiti Kebangsaan Malaysia.
