Global Warming, dynamic planetary changes, call it what you like but it
is being monitored, and those figures seem to be not good at all for
the inhabitants of the planet.
The weather here is warm and dry, and it does seem warmer.

Growing ozone hole shatters recovery hope

THIS year's Antarctic ozone hole is one of the largest on record,
despite predictions that the giant human environmental accident is
almost on the mend.
The hole covers about 28 million square kilometres as it hovers around
its usual September high, the Bureau of Meteorology said yesterday.
Depleted ozone covers the Antarctic continent and has reached towns on
the southern tip of South America, NASA satellite images show. It is
also deep.
Though smaller than the 2000 high of 30 million square kilometres, this
year's hole is much greater than last year's.
An ozone scientist at the bureau, Matthew Tully, said that changing
weather above Antarctica caused the variation.
Discovered in 1985, the hole confirmed concerns that man-made
chemicals, including chlorofluorocarbons used in refrigeration, were
destroying ozone when they reached the upper atmosphere. The thin ozone
layer protects life from damaging ultraviolet radiation. Bans on the
worst chemicals were imposed by developed countries in 1996, but the
long-lived chemicals continue to drift up.
Mr Scully said the bureau believed a clear improvement would begin
about 2010.
