Most of Australia is in the tropics, unlike North America - but you're right - rainfall has decreased remarkably over my lifetime, and all the dams and rivers are near empty. Scary - could drive one to drink.

First it was the ozone hole, and now it's this. If I lived there I'd be worried. Of course, I live here and I'm worried.

Global warming won't be all bad. If the Greenland or Antarctic ice fields melt, then Florida will be under water.
Good news - Radio City Apartments have come good (in a welcome reversal) and they do have the 2-bedroom configuration required, and they have booked. Now looking at Las Vegas - I advised to focus within a block and a bit either way from Bellagio, but definitely ABCC (Anything But Circus Circus).
