GENEVA, May 20 – In relation to some of the recent media and social media reporting, the Intergovernmental Panel on Climate Change (IPCC) wishes to clarify that, in several instances, the paper on climate scenarios authored by the Scenario Model Intercomparison Project (https://wcrp-cmip.org/mips/scenariomip/), which inputs assumptions to part of the Coupled Model Intercomparison Project (CMIP) process, has been incorrectly attributed to the IPCC.
The paper belongs to the broader body of scientific literature produced by the international research community, under the coordination of the World Climate Research Program, not the IPCC. It aims at producing a set of future illustrative scenarios that can be used by climate modellers to simulate the response of the Earth System to common greenhouse gas emissions.
The IPCC does not conduct its own research, run models or make measurements. It does not own the scenarios described in the mentioned paper, nor does it own any of the scenarios assessed in the Sixth Assessment Report (AR6). The IPCC’s role is to assess the available scientific, peer-reviewed literature relevant to climate change, currently running at approximately 50,000 papers and studies per year. The mentioned paper is within the scope of the IPCC’s next assessment.
Some of the recent media and social media reporting has focused on the scenario known as SSP5-8.5, previously referred to as RCP8.5. This was one of five illustrative scenarios (the most extreme in emissions until 2100) assessed in the IPCC’s Sixth Assessment Report covering the range of possible future developments of drivers of climate change found in the scientific literature, and is further explained in IPCC AR6 Working Group I FAQ page.
The illustrative scenarios included in AR6 describe potential society and emission evolutions starting in 2015. More recent literature reflecting the last decade of developments, such as CMIP7 scenarios, will be considered in the Seventh Assessment Report (AR7).
IPCC’s Sixth Assessment Report stated that human activities, principally through emissions of greenhouse gases, have unequivocally caused global warming, with global surface temperature reaching 1.1°C above 1850–1900 in 2011–2020. Continued greenhouse gas emissions will lead to increasing global warming, with the best estimate of reaching 1.5°C in the near term in considered scenarios and modelled pathways.
The IPCC’s last report also warned that every increment of global warming will intensify multiple and concurrent hazards. Deep, rapid, and sustained reductions in greenhouse gas emissions would lead to a discernible slowdown in global warming within around two decades and also to discernible changes in atmospheric composition within a few years.
During the current, seventh assessment cycle, IPCC will once again assess new contributions to the scientific literature, including the mentioned paper.
In order to avoid the risk of pre‑empting the outcomes of its assessment process, IPCC does not comment on individual papers or publications.

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 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).
At the Panel’s most recent Plenary Session in Lima, Peru, in October 2025, member governments agreed on the scientific content of the 2027 Methodology Report on Carbon Dioxide Removal Technologies, Carbon Capture, Utilization and Storage. There, the Panel also agreed on the 2026 workplan for the three Working Group contributions to the Seventh Assessment Report.
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.
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.

CHECK AGAINST DELIVERY
Copenhagen, Denmark, 21 May 2026
Your Excellencies, distinguished colleagues, ladies and gentlemen,
As Chair of IPCC, I thank our hosts for the invitation to address this session.
You all know what IPCC is and what it does, but let me just emphasise our unique capacity to assess the vast and exponentially growing body of knowledge on climate change, its impacts, and available responses. While every individual scientific paper matters, IPCC can place them in the context of the overall body of evolving knowledge.
And with that, let me cut straight to the topic of this session. At current levels of warming, we can already see the effects of extreme events, including intense heat, wildfires, flooding, heavy rainfall and tropical cyclones. These cause disruption and devastation, highlighting the vulnerability of our globally interconnected societies. Meanwhile, sea level rise is inexorable, posing existential risks to those most exposed.
It is now almost inevitable that we will soon exceed global warming of 1.5 degrees Celsius above pre-industrial levels, the warming level beyond which risks start to accelerate. The urgent need to enhance resilience and step up adaptation efforts is obvious. Our Sixth Assessment Report concluded that adaptation progress has been made across all sectors and regions, but that progress has been unevenly distributed with observed adaptation gaps.
Three degrees of warming, consistent with current mitigation policies, will have disastrous consequences. As we emphasised in the Sixth Assessment Report, every fraction of a degree of warming matters.
In principle, it is possible in the long-term to return warming to 1.5 degrees. But many climate impacts are irreversible. Mid-century warming levels on the pathway towards net zero matter, not just those achieved at the end of the century.
So, what is IPCC is planning for the current cycle? The word “adaptation” appears in three chapter titles of the Working Group II report on impacts, adaptation and vulnerability. This is actually three times more than in the sixth assessment cycle. This signals clearly a new emphasis on climate action. We have chapters which have not appeared in previous reports on “responses to losses and damages” and finance.
And, we are also updating Technical Guidelines, dating from 1994, on assessing impacts and adaptation. Compared to mitigation, adaptation has lacked the means to measure progress. Adaptation actions are more difficult to separate from broader patterns of investment in infrastructure and development. The update will emphasise indicators, metrics and methodologies. These should provide useful guidance on planning, including mainstreaming adaptation of a more transformational character into existing policies and practices. The guidelines will address learning, monitoring and evaluation, including adaptation targets, as well as metrics and indicators to monitor and track progress, uptake and performance.
Already, it is evident to the authors that many bodies have already made progress in developing a variety of guidelines for assessing impacts and adaptation. The challenge for the updated Technical Guidelines may lie in assessing existing approaches, rather than starting from scratch.
The target audience for the guidelines includes, obviously, negotiators with their interest in the Global Goal on Adaptation and indicators to measure progress. But other important audiences include policymakers and practitioners at the national and sub-national levels who plan infrastructure and implement adaptation measures on the ground.
Your Excellencies, ladies and gentlemen,
To finish, a few words on progress with the IPCC Seventh Cycle. All Working Groups have started work and are busy preparing their First Order Drafts for Expert Review. Working Group II on impacts, adaptation and vulnerability is holding its second lead author meeting in the Bahamas as we speak. The combined government and expert review of a Special Report of Special Report on Climate Change and Cities began two weeks ago. That report is scheduled for release next March.
We know that the Working Group Reports will start to appear in mid-2028, but the full timeline has yet to be decided. We have just opened a consultation on criteria for assessing timeline options with a view to reaching a decision at the IPCC’s next Plenary in October.
Speaking as a scientist, and on behalf of IPCC authors, I have one plea. And that is for certainty. Our 660 authors take time out from their day jobs, conducting research and teaching the next generation, to volunteer their services to IPCC. As the seventh cycle gathers pace, uncertainty is the biggest challenge to their sustained engagement.
I take this opportunity to invite the policymakers at this conference to support IPCC in bringing this debate to a conclusion.
Thank you.
Over 200 authors from the IPCC’s Working Group II gather in the Bahamas to work on the draft of the next scientific report assessing climate impacts, adaptation and vulnerabilities.
NASSAU, May 18 —The authors of the Intergovernmental Panel on Climate Change (IPCC) working on the next Working Group II report which assesses the latest science related to climate impacts, adaptation pathways and vulnerabilities are meeting in Nassau, Bahamas this week to develop the report’s first draft. This is the second time authors are meeting to advance work on the report, also known as the Second Lead Author Meeting. Taking place from 18 to 22 May 2026, this meeting brings together more than 200 authors of the Working Group II from nearly 90 countries. This marks a critical milestone in the development of the Working Group II contribution to the IPCC’s Seventh Assessment Report (AR7).
“Increasingly, climate impacts are being felt around the world. They are a present reality everywhere. The Bahamas is a living case study of the current climate realities our report must address,” said Prof Winston Chow, Co-Chair of the IPCC Working Group II
“Being hosted by a small island state is a reminder to us that the science assessment we produce has direct consequences for communities on the frontlines of climate change. We are grateful to the Government of The Bahamas for their support for our work”, he added.
Working Group II focuses on climate change impacts, adaptation and vulnerability — topics of acute relevance to small island developing states and coastal nations such as the Bahamas. In the AR7, the Working Group II contribution consists of 20 chapters. In addition to its report, the Working Group II authors will also update the 1994 Technical Guidelines for Assessing Climate Change Impact and Adaptations (TGIA).
“As a Bahamian climate change scientist, it is essential for the IPCC to advance understanding and action on impacts, adaptation and vulnerability. These are critical issues for The Bahamas and other small islands around the world on the frontlines of climate impacts. This meeting provides an opportunity for authors to witness first-hand the realities on the ground for vulnerable island communities and to encourage Caribbean experts to engage with the IPCC,” said Dr Adelle Thomas, Vice Chair of the IPCC Working Group II.
The second Lead Author Meeting provides the report’s authors with the opportunity to discuss and refine the initial drafts of their chapters, strengthen cross-chapter integration and advance the scientific assessment aimed at supporting policymakers around the world in shaping action on climate impacts, adaptation and vulnerability.
The drafting process for this report has been underway since the First Lead Author Meeting in Paris, France in December 2025. Selected authors have been developing the report based on the outline agreed by the 195-member government Panel during its 63rd Plenary Session held in Hangzhou, China in February 2025.
Following this Second Lead Author Meeting, the authors will develop the First-Order Draft which will be open for experts around the world to review and comment on.

GENEVA, May 8 – The Intergovernmental Panel on Climate Change (IPCC) has opened registration for governments and experts to serve as Expert Reviewers on the Second-Order Draft (SOD) of the Special Report on Climate Change and Cities.
Following the Third Lead Author Meeting this January, authors of this Special Report have processed comments from expert reviewers of the First-Order Draft and prepared a second draft, which will open this week for governments and experts worldwide to review and provide comments.
“Our authors have worked hard to process the tens of thousands of comments received in our First-Order Draft to present a Second-Order Draft that accounts for the suggestions, perspectives and expertise of urban and climate experts around the world,” said Winston Chow, Co-Chair of Working Group II.
”We are proud to present this new draft and would like government representatives and more experts to come forward to review and help us refine the report to one that supports and inspires decision-making on climate action in cities around the world”.
The review of the Second-Order Draft is the next step in the IPCC’s rigorous multiple-stage review process. This is an essential part of the IPCC process to ensure a comprehensive, objective and transparent assessment of the current state of knowledge of the science related to climate change. Reviews are critical in preparing IPCC reports as they ensure that the report is scientifically rigorous, includes the widest range of perspectives, and remains relevant to the urgent challenges urban areas and communities face in a warming world and changing climate.
This Second-Order Draft will also include the first draft of the Summary for Policymakers (SPM), a key product that encapsulates the report’s findings and is aimed at informing policymakers shaping climate action worldwide.
Following receipt of the review comments, author teams will prepare final drafts of the full report and SPM, taking into account review comments received. The final draft of the report will be distributed to governments for a final round of written comments on the SPM, before governments meet in plenary session to approve the SPM line by line and accept the underlying report.
Scheduled for release in March 2027, the Special Report on Climate Change and Cities will be the first IPCC report published in the seventh assessment cycle. It is also the only special report in the current cycle. The report aims to 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 options.
All review comments submitted by experts or governments are addressed by the authors. The comments and the authors’ responses, together with the drafts, are published after the report is finalized.
Interested experts can register for participation in the review here. The registration of experts closes on 26 June 2026.
The SOD of the IPCC Special Report on Climate Change and Cities is available for Expert Review from 8 May to 3 July 2026.
During the Expert Review from October to December 2025, the First-Order Draft of the Special Report on Climate Change and Cities received more than 32,000 comments from 1,365 registered Expert Reviewers around the world

GENEVA, April 23 – Experts and author teams of the Intergovernmental Panel on Climate Change (IPCC) are meeting this week at the Universidad Católica in Santiago, Chile, to advance the first draft of the Working Group I contribution to the Seventh Assessment Report (AR7). The Working Group I report covers the physical science related to climate change.
The meeting, scheduled from 21 to 24 April, is the second time the authors will be meeting in person following the first meeting held jointly with Working Group II and III in Paris in December 2025 where they began their work. The authors will meet two more times during the report preparation process to develop and refine the draft in line with IPCC’s principles and procedures.
“This is an important milestone in the preparation of the Working Group I contribution to the Seventh Assessment Report,” said IPCC Working Group I Co‑Chair Robert Vautard.
“Building on their initial discussions in Paris, authors are now advancing the detailed scientific assessment needed to develop a robust First Order Draft of our report. These scientific exchanges are at the heart of the IPCC assessment process,” he added.
The Expert Review of the First Order Draft of the Working Group I report is scheduled from 10 August to 2 October 2026. In addition, as with all other IPCC reports, the Working Group I report will undergo two further formal review stages, including a joint review by governments and experts, before the final government review and approval by IPCC member governments at the Panel’s plenary session prior to public release.
“The multi‑stage review process ensures that the report is comprehensive, balanced and policy‑relevant without being policy‑prescriptive. This is how the IPCC builds trust in its assessments,” said IPCC Working Group I Co‑Chair Xiaoye Zhang.
The author teams of the Working Group I contribution to AR7 include 193 Coordinating Lead Authors, Lead Authors and Review Editors from 62 countries – 40% new to the IPCC process. 43% of these experts are women, and 46% come from developing countries and economies in transition including three from Chile.

GENEVA, April 22 – Over 130 experts from more than 50 countries are meeting at the headquarters of the Food and Agriculture Organisation (FAO) in Rome, Italy, for the third Lead Author Meeting of the 2027 Methodology Report on Inventories for Short-lived Climate Forcers (SLCF) of the Intergovernmental Panel on Climate Change (IPCC).
“This meeting is a key moment in the development of the SLCF Methodology Report, as authors work together to consolidate the science and methodological approaches needed for a robust Second Order Draft,” said Takeshi Enoki, one the Co-Chairs of the IPCC’s Task Force on National Greenhouse Gas Inventories (TFI) responsible for preparing the report.
The SLCF Methodology Report aims to provide clear guidance on estimating emissions of 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.
The author teams will be finalising the second order draft of the report. The draft will be open for review from 31 August to 25 October 2026.
“The Second Order Draft review is a crucial step in the IPCC process, allowing governments and experts to provide feedback that strengthens the clarity, robustness and usability of the guidance before it is finalised,” said Mazhar Hayat, the other TFI Co‑Chair.
The IPCC agreed upon the outline of the 2027 IPCC Methodology Report on Inventories for Short-lived Climate Forcers at its 61st Session held in in Sofia, Bulgaria from 27 July to 2 August 2024. It will be finalized in 2027.
The TFI Bureau, also known as the Task Force Bureau, in consultation with relevant Working Groups’ Co-Chairs, selected the report’s Coordinating Lead Authors, Lead Authors and Review Editors. The full list of authors and review editors is here.

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 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).
At the Panel’s most recent Plenary Session in Lima, Peru, in October 2025, member governments agreed on the scientific content of the 2027 Methodology Report on Carbon Dioxide Removal Technologies, Carbon Capture, Utilization and Storage. There, the Panel also agreed on the 2026 workplan for the three Working Group contributions to the Seventh Assessment Report.
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.
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.

GENEVA, April 14 – The Intergovernmental Panel on Climate Change (IPCC) is gathering over 150 experts in Rome, Italy, this week to begin work on the 2027 Methodology Report on Carbon Dioxide Removal Technologies, Carbon Capture, Utilization, and Storage(CDRT-CCUS). The first meeting of authors of the Methodology Report is taking place from 14 to 16 April 2026 at the headquarters of the Food and Agriculture Organization in Rome.
The 2027 Methodology Report on Carbon Dioxide Removal Technologies and Carbon Capture, Utilization, and Storage will equip governments with a robust, up‑to‑date scientific foundation for estimating CO₂ emissions and removals from these technologies.
“This Methodology Report will serve as a fundamental reference for transparent and consistent reporting on climate action, strengthening the scientific basis for mitigation policies,” said Takeshi Enoki, the Co-Chair of the IPCC Task Force on National Greenhouse Gas Inventories (TFI).
The CDRT-CCUS Methodology Report will provide comprehensive guidance on a wide range of carbon dioxide removal and storage approaches, from CO₂ capture, utilisation, and long‑term storage to emerging land‑based and coastal solutions. It will offer updated scientific methods for assessing technologies such as direct air capture, soil and biomass-based removals, coastal ecosystem approaches, and the production of durable CO₂‑derived materials.
“Together, these updates will strengthen countries’ ability to consistently estimate and report emissions and removals across the full spectrum of methods covered by the IPCC guidelines,” said Mazhar Hayat, the other TFI Co-Chair.
The IPCC Task Force on National Greenhouse Gas Inventories is responsible for developing and improving internationally agreed methodologies and tools for estimating and reporting greenhouse gas emissions and removals by signatories of the United Nations Framework Convention on Climate Change (UNFCCC) and its Paris Agreement.
As other IPCC reports, this Methodology Report will be prepared through a structured and transparent IPCC process, with four Lead Author meetings where the report’s content will be developed and refined in line with approved guidance. It will undergo two formal review stages, first by experts and then by governments and experts jointly, before the final approval by IPCC member governments at the end of 2027.

Bangkok, March 27 – The 64th Plenary Session of the Intergovernmental Panel on Climate Change (IPCC) closed in Bangkok this evening. The session discussed the review of the Principles and Procedures that govern IPCC’s work. These should be reviewed every five years and are critical to ensuring the IPCC’s capacity to produce comprehensive, neutral, objective, transparent, inclusive, and robust assessments of climate-related science.
The Panel decided to consider the review of the IPCC Principles and Procedures at future sessions.
During the Plenary, the member governments also decided to consider the timeline of the Seventh Assessment Report (AR7).
While the Panel made no formal decision, the member governments clearly indicated that they want the timeline agreed at its next session.
“In IPCC, we use our best endeavours to achieve consensus. Sometimes, as we pursue our best endeavours, we strive in slightly different directions. But I think the spirit of compromise and flexibility in IPCC was shown in the end,” said IPCC Chair Jim Skea, addressing the delegates in closing the session.
During the four-day session, the Panel also considered the financial situation and fundraising for the IPCC Trust Fund for this cycle and beyond to ensure its long-term sustainability. Supported entirely by voluntary contributions from member governments, the IPCC Trust Fund is the key mechanism enabling participation by developing-country governments and scientists in the IPCC’s work.
The Panel also agreed on the work programme of the Task Group for Data Support for Climate Change Assessments.
The 64th Plenary Session of the IPCC was also the last one for the IPCC Secretary Abdalah Mokssit, who led the IPCC Secretariat for the past decade, and will retire in the next few months. On this occasion, the delegates, Bureau members, observer organizations, and staff expressed appreciation for the outgoing Secretary’s strong commitment and rich contributions.
