Extreme cold temperatures, rainfall and intense fog in the months of December and January are not something new for north and northwest India. And yet, this December feels a little extra cold. I too was wondering the same for the past few days. I have my photos from last year when I went out in the sun during this time. I cannot go out of my blanket now. Here is what is going on:
The surprisingly cold December this year could just be another example of extreme climates becoming more and more frequent, a result of climate change. Across the world, the frequency and intensity of both heat waves and cold waves have increased in the last few years, and are predicted to increase further. An unusual and powerful spell of western disturbances, originating in the Mediterranean sea, has made the Indian subcontinent shiver for the past ten days.
And we are expected to see more of this in coming years.
So just keep calm and chill.
