The IPCC Working Group I (WG I) aims at assessing the physical scientific basis of the climate system and climate change. Its main topics include: changes in greenhouse gases and aerosols in the atmosphere; observed changes in air, land and ocean temperatures, rainfall, glaciers and ice sheets, oceans and sea level; historical and paleoclimatic perspective on climate change; biogeochemistry, carbon cycle, gases and aerosols; satellite data and other data; climate models; climate projections, causes and attribution of climate change.

 

 

 

 

 

 

 

Latest news: IPCC Special Report on Global Warming of 1.5°C

Expert Review of the First Order Draft and start of the Third Lead Author Meeting


MALMÖ, Oct 23 - Nearly 500 experts from around the world took part in the recent review of the First Order Draft of the Intergovernmental Panel on Climate Change (IPCC) Special Report on Global Warming of 1.5°C (SR15). At a meeting in Malmð, Sweden, this week, the authors will work on addressing nearly 13,000 comments from expert reviewers in 61 countries as they prepare the Second Order Draft.


The Third Lead Author Meeting for the Special Report on Global Warming of 1.5°C is being held in Malmð at the kind invitation of the Swedish government. The meeting is being hosted by the Swedish Meteorological and Hydrological Institute (SMHI) and taking place at MalmõMässan from 23-27 October 2017.


This week's meeting marks the culmination of the first round of expert review of the draft report: Global Warming of 1.5°C: an IPCC special report on the impacts of global warming of 1.5°C above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty.


Key statistics


  • Two thousand experts from 124 different countries registered to be reviewers (based on citizenship)
  • Overall, the First Order Draft of the Special Report on 1.5°C attracted 12,895 review comments.
  • These comments came from 489 expert reviewers representing 61 different countries.
  • Based on citizenship, half of expert reviewers were from Europe (51%). North America, Central America and the Caribbean accounted for a further 19%, Asia (13%), South America (7%), South West Pacific (6%) and Africa (5%).
  • A third (31%) of expert reviewers were female, two thirds (69%) were male.
  • Three quarters of reviewers (77%) were citizens of developed countries, 23% of developing countries.
  • Chapter 3 on impacts of 1.5°C global warming on natural and human systems attracted the most review comments (3,894, 30% of total comments). See full breakdown below.



All IPCC reports go through two stages of formal review. Feedback received in the first round of expert review will be incorporated, as appropriate, by the authors into the Second Order Draft. The Second Order Draft will then be open for review by governments and experts around the world from 8 January to 25 February 2018. The final report is due to be finalised and made publicly available in October 2018.


"The Second Order Draft will include a first version of the Summary for Policymakers (SPM), which is a distillation of the most policy-relevant findings from each chapter. Governments have asked us for a very concise SPM this time (about 10 pages)," said Valérie Masson-Delmotte, WGI Co-Chair.


The IPCC's comprehensive review process ensures that the reports cover the most up-to-date scientific, technical and socio-economic findings, and are representative of a broad range of independent expertise from developed and developing countries.


"An indicator of success for the IPCC process is the involvement of the scientists worldwide. Having about five times more expert reviewers than authors and nearly 13,000 comments is crucial. There is not a single section, table or figure that did not receive any comments," said Masson-Delmotte.



Of the 86 experts from 39 countries selected by the members of all three IPCC Working Groups in February to be authors of the Special Report on 1.5°C, 38% are women, 51% come from developing countries and economies in transition (based on citizenship) and 26% are new to the IPCC process.


The IPCC Special Report on Global Warming of 1.5°C is being prepared in response to an invitation from the 21st Conference of the Parties (COP21) to the United Nations Framework Convention on Climate Change. The report will be wide-ranging, assessing possible ways for limiting global warming to 1.5°C, as well as considering these issues in the broader context of sustainable development. More details are available on the report page.


The Special Report on Global Warming of 1.5°C is part of the IPCC's sixth assessment cycle. This cycle will produce three Special Reports, a Methodology Report on national greenhouse gas inventories and the Sixth Assessment Report (AR6), consisting of contributions from Working Groups I, II and III and a Synthesis Report.


 

 

 

 

 

 

 

 

 

IPCC calls for nominations of authors for the Sixth Assessment Report
The deadline for the nominations is Friday 27th October 2017 midnight GMT+1

 


The Intergovernmental Panel on Climate Change (IPCC), the UN body for assessing the science related to climate change, is calling for nominations of authors for the Sixth Assessment Report (AR6).

"We are seeking scientists with expertise across the disciplines assessed by the IPCC," said Hoesung Lee, Chair of the IPCC. "We also hope that more scientists from developing countries and more women scientists will be nominated as IPCC authors to give us diverse author teams that can provide a range of relevant perspectives."

The report outline consists of chapters with indicative bullets, listing topics to be considered in the assessment. Expertise is sought in the call for nominations to undertake the assessment of these topics.

To register as an Expert Reviewer please complete the registration form via the dedicated website: https://www.ipcc.ch/apps/comments/sr15/fod/register.php

The expert review of draft reports is a central component of the IPCC assessment process that aims to ensure that the Report represents scientific findings comprehensively and in a balanced way, as judged by a very broad range of experts. Expert Reviewers can play an important role in identifying the key literature, ensuring a balanced interpretation and placing topics in context. The SR15 Lead Authors will consider all review comments on the FOD.

Registration will be available from 17 July 2017 and will close a week before the review ends, on the 17 September 2017. All review comments must be uploaded on or before Sunday, 24 September 2017.
