Outline of Final Research Achievements |
We have analyzed several ice cores obtained from alpine glaciers as Mt. Wrangell and Aurora Peak in Alaska, and shallow ice cores from northwestern and eastern Greenland Ice Sheet, which were newly drilled in 2014 and 2015, and reconstruct climate and environmental changes from the Little Ice Age (LIA) to present. From the late LIA to present, we found obvious climate shifts of air temperature and precipitation amount in 1700s and 1850s in both of Alaska and Greenland. The changes both of air temperature and precipitation showed seesaw relationship between Alaska and Greenland. We assume that the changes of air temperature and precipitation are associated with the shift of the route of the Jest Stream. In 1990s, we found an another climate shift. The variation tendencies of air temperature and precipitation are different from those before the climate shift.
