Speaking about the rains that hit the state and the resultant landslides, Sukhu said these are first signs of climate change. "We have never seen such spells of rain in the state. Areas that never got rains like Spiti are getting rains. Earlier it would rain in July only but this year we got rains in April, then in July and several spells in August. This is nothing but climate change. Landslides converted into mud slides and we saw roads and communication being cut off. 400 lives have been lost and 16,000 houses were destroyed. We saw unprecedented damage to life and property," Sukhu said.
