OK, I've been having a hard time wrapping my brain around some of these temperatures. Seven degrees? That's not so bad, although it never gets quite that cold here, even in winter. It did get down to 12 last winter... hang on, that was 12 C here last winter as our coldest day in decades. You guys mean 7 F - that's minus 13 C, it NEVER gets that cold anywhere in Australia (except in my old boss's freezer).
It's going to be cold here tomorrow, they said it will be down to 21. The water temperature here is 22. That's C, around 70 F.
I would really appreciate a few snowballs down this way, it would be a relief from the heat.
Mind you, you can't beat Aussies for practical jokes. Thinking about ice reminded me of this amazing guy, a sort of prequel to Bill Gates, who had been saying for some time (in all seriousness) that we could solve a lot of our coastal city water shortages, by towing icebergs up from Antarctica; we'd lose some through melting on the way but the bigger ones would still give us plenty of freshwater, making the enterprise worthwhile.
Then he actually did it!
