Societal Relevance

Abstract. The Tibetan Plateau is of peculiar societal relevance as it provides freshwater from the so-called “Water Tower of Asia” to a large portion of the Asian population. However, future climate change will affect the hydrological cycle in this area. To define parameters for future climate change scenarios it is necessary to improve the knowledge about thresholds, timing, pace and intensity of past climatic changes and associated environmental impacts. Sedimentary archives reaching far back in time and spanning several glacial–interglacial cycles such as Nam Co provide the unique possibility to extract such information. In order to explore the scientific opportunities that an ICDP drilling effort at Nam Co would provide, 40 scientists from 13 countries representing various scientific disciplines met in Beijing from 22 to 24 May 2018. Besides paleoclimatic investigations, opportunities for paleomagnetic, deep biosphere, tectonic and paleobiological studies were discussed. After having explored the technical and logistical challenges and the scientific opportunities all participants agreed on the great value and need to drill this extraordinary archive, which has a sediment thickness of more than 1 km, likely covering more than 1 Ma.

Abstract Aims Climate change in the near future may become a major threat to high-altitude endemics by greatly altering their distribution. Our aims are to (i) assess the potential impacts of future climate change on the diversity and distribution of seed plants endemic to the Tibetan Plateau and (ii) evaluate the conservation effectiveness of the current National Nature Reserves (NNRs) in protecting the endemic plants in the face of climate change. Methods We projected range shifts of 993 endemic species to the years 2050 and 2070 under two representative concentration pathway scenarios using an ensemble species distribution modeling framework and evaluated range loss, species-richness change and coverage of the current conservation network considering two dispersal scenarios. Important Findings In a full-dispersal scenario, 72–81% of the species would expand their distribution by 2070, but 6–20% of the species would experience >30% range loss. Most species would shift to the west. The projected species net richness would increase across the region on average. In a no-dispersal scenario, 15–59% of the species would lose >30% of their current habitat by 2070. Severe species loss may occur in the southeastern and the eastern peripheral plateau. Seventeen percent of species ranges are covered by the NNRs on average and may increase in the future if species disperse freely. We found a significant difference of species redistribution patterns between different dispersal scenarios and highlighted the importance of migration in this region.
