Well I can't say that the summers have gotten noticeably hotter for me, but the last few years our winters have been getting ridiculous. Two winters in a row we've gotten into freezing temperatures on several occasions. To put that in perspective that happens MAYBE once a year. That's a big maybe too.
I live in the tropic. So we have basically two temperatures. Hot and hotter.
Winter is mild here in Colorado. It can get damned cold at times, though. It snows here and there, but usually melts off in a day or two, except up in the mountains. Summer is comfortable; not too hot.
It was cold the last few days, and by cold I mean like low 50s. FREEZING. 
It's 21° here. 
When GG says 23-30 degrees he is talking about it being pleasantly warm. When raven talks about 21 degrees he is talking about it being below water freezing level...
You can't compare temperatures in different scales, we need a common one. I suggest we use the Kelvin scale as it's the only one based on a fundamental truth and not some arbitrary perk. It has the added benefit of not having negative temperatures.

My experience with "climate change"? The only really tangible change has been the drought. Now that seems to be going away, and it's back to wet spring days! 
Here's hoping for a wet Christmas!
For me, I remember it used to snow at winter when I was a kid under 13. Then progressively each year the winters would be wet but no snow for years. Now recently in the past few years it has started snowing a lot in the winter, grinding the whole country to a halt.
Also the summers have gotten hotter and hotter and its not unusual to see weeks of 23C - 30C heat here in the summer months.
