The Mechanism of Meteorological and Environmental Changes
We aim for the elucidation of the mechanism of climate and evironmental changes for 800kyr.

One of the informations extracted from ice core is dust concentration variation. Dust concentration in ice core increases with the decrease of air temperature, that can elicit that terrestrial dust soared in the air heavily because sea level decreased and land territory spread during glacier period. The mechanism is suggested that the dust pumped into the sea activate phytoplankton, and phytoplankton absorbed CO2, greenhouse gas, and the decrease of CO2 accelerated the global colding. We aim for the elucidation of such as mechanisms.
