Weird weather

Today, the temperature suddenly declined.

The lowest temperature is under 20 degree today, like autumn.

There are so many weird phenomena these days. Somedays, it squalled so hard even the sky is blue, there are partially cloud.

Some says that this is the effect of global warming.

I don't know exactly if it is or not.

Anyway, I dislike too hot days and humid days, therefore today is preferable for me...
