The scientific community on global climate forecast future trends, and the "global warming" argument instead.
In the early 20th century, 70 in climate, "said cooling" became mainstream. Gardner, who in 1971 published Dans Greenland ice core oxygen isotope spectral analysis results show that the Earth's climate changes in the orbital period of 10 years, including 9 years as a cold period, 1 million years for the warm period. Click here to law, the current climate of warm periods is nearing completion. Japan Meteorological Agency Asakura is the author predicted in 1973, the Earth will enter the 21st century "Little Ice Age IV." Institute for Environmental Studies, University of Wisconsin Bryson that the Earth is being very slowly into another big ice age. Then "Warming said," is based on thermal pollution to the atmosphere, the theory is now mainstream.
70 years, Brown University in the United States held a special "end of the current interglacial period when and how to end" the seminar, scholars have cited examples show that the current global temperature has begun to decline. They said the change from warm to cold can be less than 500 years, if humans do not interfere, the current warm period would end quickly, global cooling and the corresponding environmental changes will come along. The two sponsors of the meeting even to the then U.S. President Richard Nixon issued a warning letter. This "Ice Age will be temporary" point of view lasted for 20 years. |
