Its to humid this year. It due to global warming. Global warming is the long-term warming of the planet's overall temperature. Thats why we all use air conditioners, but is it actually useful. Although it gives us cold air but its a disaster for our planet Earth. It is because it releases a great amount of gas known as Chlorofluorocarbon (CFC) which is a major reason for global warming. So whenever we open our AC it releases the gas. So always rethink before your action.
