Have you noticed that the average temperature is increasing? Maybe not in numbers but the heat index had really changed. During summer, we used to turn on the air conditioner at around 10 am and turn it off at 4 pm. But now it's already hot by 9 am that we had to run the air conditioning and turn it off after 5 pm (yesterday it was 5:30 pm). I guess it is the effect of global warming.
Anecdotal evidence like that is mostly just confirmation baias; When it's hot people who are inclined think global warming is happening. When it's cold people are inclined think it's evidence that it's not happening. Weather and anecdotal temperature observations don't prove much. There's always crazy weather.
