Dehradun: The accelerating pace of deforestation has lead to fluctuation in day and night temperature of Uttarakhand, reveals a study by Wadia Institute of Himalayan Geology. 

Studying the temperature of last 51 years, the scientists of the institute have derived that days are getting hotter and nights are three times cooler than normal.

From 1960, the scientists of Wadia Institute are recording the temperature of Gangotri, Joshimath and other altitude regions of Himalayan ranges.

Considering the figures recorded in initial years, there was hardly any difference in the day and night temperature.

Slight changes started to become visible in last 20 years. During this time, the days were hot and nights were 50 percent cooler than normal.

However, the last 10 years study reveals that fluctuation in day and night temperature increased by three folds.

Scientists claim that owing to rampant felling of trees in Uttarakhand, the moisture content of the soil has decreased by 20-40 percent, affecting the climatic cycle.

“Plants and trees maintain the moisture in the climate. Excessive cutting of trees affect this balance of nature,” said Director of the institute, Professor Anil K Gupta.
He said, “Government should prepare special strategy to prevent over-exploitation of forests.”

Interestingly, sweltering heat is an indication of heavy monsoon. If temperature falls the rainfall season is too affected. Besides, poor moisture content affects the fertility of the soil.
