Australia's
climate has changed for good, say scientists
Australia's
top climate scientists and science bodies have for the first time
endorsed a major report that says the country's climate has in some
cases shifted permanently.
Last
summer, 123 weather records were broken in 90 days.
As
well as heat waves and unprecedented temperatures, there was heavy
rainfall and major flooding.
The
Climate Commission said it was not a one-off and Australia has a
future of weather records yet to be broken.
The
peer-reviewed assessment noted that there was strong consensus around
a central finding that in some cases the weather has changed for
good.
While
it says the number of tropical cyclones will not increase, the
influence of climate change means they will become more intense.
One-in-100-year
flooding events are already becoming more common, and sea levels have
risen 20 centimetres since 1880.
Report
author Professor Will Steffen said a pattern was emerging in which
the south-west and the south-east of Australia have become drier.
"That
tells us for the future that we would expect to see dry conditions
more often, more droughts in the future and very importantly we don't
expect to see the previous pre-climate-change weather conditions come
back.
He
said some changes in patterns will lock in probably for centuries.
