 note = {application/pdf, A trial was made to estimate the effect of solar activity on the global warming by using temperature proxies (sea surface temperature, {}^{18}0 content in coral leaves, and freezing date for Lake Suwa) and solar activity indices (aa index and cosmogenic isotope {}^{10}Be). By matching these data each other for the period from 1650 AD, it is concluded that the solar activity is the main factor in the increasing trend of the global temperature in this century. The Lake Suwa data showed an increase near 1500 AD, which was consistent with an increase in the solar activity found in the {}^{10}Be data.},
