Australian climate

Australia is not only the driest continent on earth, it also has a harsh climate. It is going through the worse drought since it has been keeping records. Australia's fresh water supply is low and not getting better soon.

The ozone hole above the Antarctic makes it health-wise dangerous to stay outdoor in the Australian sun, sun-burns are common and can lead to Melanoma, a skin cancer which can be fatal. Ozone depletion is worse around this time of the year.

Chris, if you want to know what Australia can be like without ozone, stick your head into a microwave oven for a few minutes.

While I don't expect Chris will be likely to take up your suggestion, there is a difference between UV light and microwaves.

Microwave oven, 2.450MHz (megahertz), which is a wavelength of 12 centimetres.
This frequency vibrates the water molecules which generate the heat inside the food.

Ultraviolet light is around 15,000,000 gigahertz which is a wavelength of 20 nanometres.

A good slop of sunscreen will guard against UV light, but would be useless against microwave radiation.

Reply #51 emucentral's post

Quite right emu, incidentally the cavity magnetron (invented of course by Australia's
cousins in the UK)  is the device behind a microwave oven Radar and the  plasma
lighting system


Australia is envied for having such a successful presence in the East
and has  achieved this  with a miniscule population.

Australia  should be used as an example, not an object of envy .

Great idea, Cestmoi.

All those at Chinese Universities should be able to read these posts, even some of those which disappear.

How about they could also read The Standard and SCMP as well as watch ATV and TVB without any censorship, that'd be good wouldn't it?
