The thing is, historically it just ain't true.

It's the temperate and polar zones which are colder that have been getting warmer summers and more mild winters.

I don't see that the tropic zones are having super extreme heat or more rainfall.  In fact, hurricane activity has vanished pretty much for example.

And where might you be living?  Not in the tropics, I'll be bound. There's Typhoon Neoguri,perhaps the strongest typhoon to strike China since 1949. There's Nargis in the Bay of Bengal the most devastating cyclone to strike Asia since 1991. There's Fengshen that made landfall in the eastern Philippines, bringing heavy rain and strong winds and causing widespread floods and landslides that left 224 people dead.  It also contributed to the death of almost 900 people in an overturned ferry.

Last year we in the Philippines were subjected to a slew of destructive storms, floods and droughts. Material damage ran into the billions and too many people died. It's hotter too - up to 32 isn't too bad, 33 is getting warm and by the itme it's 34 even the Filipinos are complaining.  It went over 36 this year.
