The conditions of global warming
Earth's climate warming and a large number of human caused greenhouse gas emissions of the greenhouse effect. However, the Japanese and Danish researchers recently pointed out that the increase in greenhouse gases caused global warming is not the only reason for changes in solar activity which also played a role.
According to "Japanese Economic News" reported that Japan's Yokohama National University Research Institute of Environmental Information Ito professor of public discipline has produced a chart. From the map, the past 200 years the average temperature of the Earth and the solar magnetic field strength basically consistent with the curve. Ito public Ji concluded that solar activity is also affecting the climate warming, the only greenhouse gas warming may increase the explanation is not comprehensive enough.
Solar activity on the Earth's temperature has been the impact of the experts concerned for a long time. In general, the number of sunspots, the intense solar activity. For example, historical data has been recorded, the year the 17th century when very few sunspots, when the Earth's climate is relatively cold. But the ground was the detection information also showed that the strength of solar activity caused by the change of solar radiation energy variation of only 0.1 percent, so small changes in the climate seems to be insufficient to bring too much influence.
However, the recent international space scientific community there is a hypothesis that changes in solar activity will change over the Earth's cloud cover, "enlarge" the impact of the Sun on the Earth, about climate change. This hypothesis put forward the Danish scientists speculate,Earth's cosmic rays can be more stable, so that part of the atmosphere-so-easy to generate, thereby absorbing the sun's massive radiation, to reduce global temperatures. However, at the peak of solar activity released from the high-speed stream of charged particles, cosmic rays can interfere with the Earth, not to cloud formation, thus leading to Earth's temperature increases. At present, the Danish researchers are studying cloud formation and the various factors, so as to demonstrate the hypothesis.
Japanese experts have put forward, although the changes in solar radiation energy rate of only 0.1 percent, but they found that the energy can change the Earth's atmosphere for the absorption of solar UV changes in the rate of a few percent, which would increase the absorption of atmospheric Ozone Layer temperature increases. Japan's Meteorological Research Institute in charge of the second small temple Bangyan, the ozone layer the change in temperature will affect the troposphere, the cold snap and the impact of the monsoon, it is not clear that the mechanism of the Earth's warming have little impact. In order to continue to study this subject, such as small Temple Bangyan member international research team has been working since last year.
