has changed since we have been children...the hottest months will remain the hottest, and the coldest are the coldest. Climate change WONT affect that, what it does affect is hot or cold it gets...

so yeah I can say this past winter was the warmest winter I experienced because I can CONFIDENTLY say that there were no 80 degree days in December when I was a child, but there were quite a few this past year. But ppl who live in areas where seasons don't exists and flow into one another seamlessly (i.e. the weather is always within 20 degrees anytime of the year) wouldn't recognize a change at all...only ppl with TRUE seasons are going to see it.
