主题：【原创】地球还在变暖吗？ -- 井底望天

In 1999, a report by the Working Group on Himalayan Glaciology (WGHG) of the International Commission for Snow and Ice (ICSI) stated: “glaciers in the Himalayas are receding faster than in any other part of the world and, if the present rate continues, the livelihood of them disappearing by the year 2035 is very high”.

The prediction that “glaciers in the region will vanish within 40 years as a result of global warming” and that the flow of Himalayan rivers will “eventually diminish, resulting in widespread water shortages” (New Scientist 1999; 1999, 2003) is equally disturbing.

In 1998, researchers LA Owen and MC Sharma Showed, by studying the longitudinal profiles of the river, that between 1971 and 1996, the Gangotri Glacier had retreated by about 850 m. This would yield a post-1971 retreat rate of 34 m a year. For the post-1971 period, the 61-year (1935-1996) data of GSI too shows that the retreat rate is about 28 m/year, indicating a clear increase in the rate after 1971. The 1996-1999 data of Naithani and associates too matches this general trend of an increased rate.
