Glacier Researchers Gather at IPCC Meeting in China

Researchers from several countries gathered in July to advance their work on a report that will assess the state of research on glaciers and related topics. The IPCC meeting took place in Lanzhou, China, the capital of the province of Gansu in the central part of the country, close to a number of glaciated peaks in the Qilian Mountains. This location reflects the focus of the document, the Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC) of the Intergovernmental Panel on Climate Change (IPCC). This report traces cryosphere-ocean links, particularly the contribution of meltwater from the Antarctic and Greenland Ice Sheets to sea-level rise, and also considers other topics related to oceans and the cryosphere. This event was the third lead author meeting for SROCC.

The report’s Chapter 2, High Mountain Areas, examines a variety of topics which include observed and projected changes in glaciers, permafrost and snow, as well as links to climate, hazards and water resources. It also discusses risks for societies and the strategies to respond to these risks. The full chapter structure can be found in the outline of the report, which was approved last year.

This chapter is being led by two Coordinating Lead Authors: Regine Hock, a glaciologist and hydrologist from the University of Alaska, and Golam Rasul, an economist and rural development specialist from the International Center for Integrated Mountain Development in Nepal. The 13 Lead Authors come from four continents and represent 10 countries—the U.K., France, Norway, Sweden, Switzerland, Austria, Russia, China, Japan, Ecuador, the U.S. and Canada.

Activities at the Meeting

The IPCC meeting, hosted by the State Key Laboratory of Cryospheric Science of the Chinese Academy of Sciences, was held on 23-27 July at the Lanzhou Hotel in Lanzhou. Shichang Kang, the director of the laboratory, coordinated the event and served as host.

The meeting was opened by Panmao Zhai, co-chair of IPCC Working Group I and secretary general of the Chinese Meteorological Society. The first speech was given by Yun Gao, the deputy director of the Science and Technology and Climate Change division of the China Meteorological Administration, who emphasized the country’s commitment to the IPCC and to international cooperation more broadly.

The next address was given by Weihua He, the vice-inspector of the Gansu Science and Technology Department. She emphasized the importance of developing a low-carbon economy in the province, which could contribute to poverty reduction while improving economic and environmental quality. She said that she could envision “a new happy and beautiful Gansu,” and closed her speech with wishes for the meeting’s “great success.” In the evening of the meeting’s inauguration, the provincial government also sponsored a performance by a troupe of folk dancers, who presented the diverse cultural styles of the ethnic groups in central and western China, and also showcased developments in Chinese media.

The meeting drew over 100 participants from 30 countries. In addition to attending plenary meetings, the chapter teams discussed the comments which they had received from experts on the First Order Drafts of their chapters. They coordinated with each other to promote the integration of the chapters, and also began the planning of communication products. They advanced as well on five cross-chapter boxes which address topics that span the report’s topics. The discussions continued at meals and in the evenings.

This meeting was distinguished by the relatively large proportion of women among the lead authors and by the international diversity, with representatives from more than 30 countries across six continents and the Pacific. It received wide coverage in a number of Chinese media outlets.

After the conference, a number of participants set off on a four-day tour of the province. Their travels included a visit to the Qilian Mountains, a glaciated range which forms the border between Gansu and the neighboring province of Qinghai. Although severe flooding had damaged roads, preventing the group from reaching Laohuoguo Glacier, they did explore regions up to 3780 meters, where they saw large herds of yaks.

After the tour, a conference was held on 31 July and 1 August on cryospheric changes and their regional and global impacts. A number of authors from Chapter 2, including Shichang Kang, Regine Hock, Miriam Jackson and Stephan Gruber, gave talks at this conference.

Comments on the Meeting

Hans-Otto Poertner, co-chair of IPCC Working Group II, described the meeting. “We are grateful for the comprehensive feedback we received in the first Expert Review of this report,” he said. “By ensuring that the latest scientific knowledge is included in our assessments, the reviews help us to provide the best available basis for global climate policy. The outcomes of our lead author meeting in Lanzhou will take us a huge step closer to this goal.”

“ We believe [the IPCC Special Report on the Ocean and Cryosphere in a Changing Climate] will help policymakers better understand the changes we are seeing and the risks to lives and livelihoods that may occur with future climate change,” said IPCC vice-chair Ko Barrett. “The gracious hospitality of our hosts is much appreciated,” she added.

Outreach Events and Upcoming Activities

In conjunction with the meeting, outreach events were held at Lanzhou University on 24 July and at the State Key Laboratory of Cryospheric Science on 26 July. IPCC Bureau leaders, Shichang Kang, and several lead authors spoke. They presented the outline of the report to local audiences, discussed major findings of earlier IPCC reports about changes in climate and in mountain and coastal environments, and reviewed issues specific to China and other Asian countries. At both events, speakers emphasized the importance of international cooperation and the great advances of Chinese researchers. One participant described the comments of Debra Roberts, co-chair of IPCC Working Group II, at the first event as “deeply inspiring.” The participant continued, “She really renewed my optimism.”

The participants left the meeting ready to begin the process of preparing the Second Order Draft of the report. This draft will be circulated for review by experts and governments in November 2018, and will be reviewed and revised at a fourth meeting in March 2019 in Kazan, Russia. The following draft will be reviewed by governments, and the report will be completed in September 2019. The recent meeting provided highly motivating support to this long process, immersing the authors for several days in a vulnerable context of a country, impacted by glacier retreat as well as sea level rise, which is a central player in international climate affairs.

Recent record-breaking heat waves have affected communities across the world. The Extreme Heat Workshop will bring together researchers and practitioners to advance the state of knowledge, identify community needs, and develop a framework for evaluating risks with a focus on climate justice.
