Prime Minister Narendra Modi on Sunday expressed concern over global warming.
"All of us are experiencing global warming and climate change now," Modi said in the 38th edition of his monthly radio programme "Mann Ki Baat".
"There was a time when winter would set in even before Diwali. And now, December is knocking on our doors, yet winter is advancing at a leisurely pace."
But Modi made no reference to the smog that enveloped the capital recently, raising serious environmental and health concerns.
