I believe the reason why we see so many changes in the recent time is because of climate change. There are times when we would not see a cloudy sky and suddenly, it would begin to rain heavily with flood and there are times where the heat would be so much we would be expecting the rain. In the previous years, it was more easy to predict the weather and we know the season we are about to enter but in today's day, it is so hard like you said and I believe it is all about climate change.
Hmm. The climate change is the reason for it and the impact of climate change is negative and somehow we are reasonable for it also.
