Climate in Tamil Nadu

I think this summer is too hot when compare with the previous summers. The climate becomes so hot for the past one week in many places like Salem, Erode, Vellore in Tamil Nadu.

The main reason for the summer becomes too hot every year is that the holes of Ozone becomes bigger than every year. The Ozone is a very important layer which protect the earth from the sun by avoiding the over heat.

Why this summer is too hot?
