This year in Kolkata, we are facing severe trouble from lightning. In the previous years when it rained, lightning was much less. This time, even before it starts raining, lightning starts, and it reaches the ground, taking lives. As soon as the clouds start appearing, lightning bolts reach out to the ground or tall buildings. Till date, 28 people have lost their lives due to lightning in Kolkata and surrounding regions. Pollution is a increasing problem in almost all metropolitan cities, including Kolkata. Can this sudden increase in lightning strikes be accounted by the pollution? Or is their some other explanation for this rise?
