yes, in my hometown there is no more snow in winter while 40 years ago i was happily cross-country skiing there. On the positive side - the peaches, apricots, cherries, etc. - the stuff of my childhood dreams sold back then only at farmers markets at astronomical prices by the traders from South - is now easily growing there in people's backyards/gardens. Though not oranges/mandarins nor watermelons yet - seems needing a bit more warming which looks to be just a matter of [pretty short] time.
In Christchurch we are also getting a lot more mosquitoes than I recall as a child*, which you may get with a warmer climate, so it definitely isn’t all wins.
* Lots of possible reasons for apparently more mosquitoes: perhaps they are evolving to match the environment here?
