But I'll never live in the snow belt. It takes about 5 minutes to recover from heat once you get in air conditioning, compared to the hour or so it takes to warm up again coming in out of the cold (I used to live in Chicago, I know cold).
It has been funny watching the global warming arguement from here though. Since that vicsious spike in 1990 things here have been definitely cooler. We went from snow every 5 years to snow every year (not "real" snow, it never sticks here, just white crap falling from the sky and screwing up traffic for a couple of hours), and the last couple years we've had multiple snow or near snow (melts before hitting the ground but if you work in a tall building you can see it) days. Meanwhile the last few summers have been comparitively mild.
There must be some frost impeding the operation of your thermometer. - We frequently have such temperatures in the inland bay area, and we're 500 miles north of you and a couple of thousand feet lower in elevation. - Back in the 50's it would hit 120 F. in Walnut Creek at least 4 or 5 times per year; now it never makes it that high.
