Pollution Reduces Rainfall in Mawsynram, World's Wettest Place

Pollution Reduces Rainfall in Mawsynram, World's Wettest Place

Mawsynram in Meghalaya, known as the world's wettest place, is getting less rain.

Scientists found that tiny particles called aerosols in the air are to blame.

These particles come from pollution like car exhausts, burning biomass, and industrial activities.

Over the past decade, aerosol levels have gone up by nearly 15%, while rainfall has dropped from 10,200mm to 8,800mm per year.

These aerosols trap heat and make it harder for clouds to form and produce rain.

The study shows that pollution from far away can affect local weather, even in places like Mawsynram that are usually very clean.

Local activities like burning biomass also add to the problem.

This means that both distant and local pollution are making it rain less in Mawsynram.
