Research Abstract

Greenland temperature change affects melting of Greenland ice-sheet, which in turn cause global sea-level change. Therefore, it is critical to understand Greenland temperature change and the mechanisms. With this KAKENHI, the extraction line and system to reconstruct temperature has been established, and the measurements for the past 2000 years of NGRIP ice core have been completed with good precision. Finally, it was found that NGRIP experienced a similar temperature history with GISP2 over the past 2000 years.
