Demographic history of Japan before the Meiji Restoration papers of the Shōsōin (8th century) and others, as well as remnants of specific periods. Since Kyōto (or Heian-kyō) became the capital of Japan in 794, it has been one of the most important cities in Japan. Hiraizumi and Kamakura flourished under Northern Fujiwara clans (during 12th century) and Kamakura shogunate (1192 to 1333), respectively. The urban area of Kyōto suffered from the Ōnin War (1467 to 1477) and split into two districts, but coalesced into a great city of more than 400,000 inhabitants after the end of Sengoku period. The Christian missionaries led by Francis Xavier reported that the
Physical impacts of climate change associated with global warming will tend to stabilize marine gas hydrate deposits. Models have been used to assess the effect that climate change will have on the carbon cycle (Meehl "et al"., 2007:789-790). In the Coupled Climate-Carbon Cycle Model Intercomparison Project, eleven climate models were used. Observed emissions were used in the models and future emission projections were based on the IPCC SRES A2 emissions scenario. Unanimous agreement was found among the models that future climate change will reduce the efficiency of the land and ocean carbon cycle to absorb human-induced CO. As a result, a larger fraction of human-induced
