Abstract

Currently occurring rapid warming in the Arctic could affect global environmental changes through sea level rise and remote atmospheric effect. The surface melting of the Greenland Ice Sheet (GrIS) involves various uncertainties, which are issues to be elucidated for accurate climate projections. To clarify how the atmosphere, snow/ice, and glacial microbes in the GrIS affect the ice sheet change under global warming, the SIGMA and SIGMA-II projects were conducted from FY2011 to FY2019. In parallel, big Arctic research projects such as GRENE and ArCS were also done, which accelerated the Japanese Greenland researches. This paper describes the research results of the SIGMA and SIGMA-II projects as well as the related research projects in the categories of (1) in-situ observations of the atmosphere, snow/ice, and glacial microbes, (2) ice core drilling, (3) satellite observation, and (4) numerical modeling. Furthermore, we discuss current issues in these studies, a linkage to the Cryosphere subject of recently launched ArCS II Project, and the importance of capacity building.
