You can't notice it personally without doing science. You can't just remember how hot it was when you were a kid and know that global warming is happening. That's what the GP was talking about and what I'm responding to. Obviously scientists can measure it with suitable instruments and techniques but casual observers can't. I think you're arguing with a strawman by bringing floods and fires into it. But even if you want to go there, experiencing one flood in your life doesn't tell you that the frequency is higher than it was 30 years ago. There just isn't enough data or valid statistics in one person's personal experience and feelings.
