Read the article I attached in the first comment.
Also, your comment is an example of what I call Observation Bias, meaning people only know what they observe in their life, where they live or visit. Then they take this single data point of observation and generalize/project it across all space and time. Very small view and arrogant in a way to think that truth is only what we conclude from our own experience or observance.
Check out this graph below. Do you think temperature changes on our planet?

I said, from my own experience. I never said, it was on behalf of the world. If you misunderstood my comment, that would be my fault. I should have explain it better. And don't take it personally..
