Australia
Could Be Entering a MEGA DROUGHT That Lasts 20 Years

October, 2018
Australia
could be entering a mega-drought predicted to last 20 years, an
expert has warned.
Forecaster
Kevin Long from Bendigo, Victoria, predicts that the record dry
of 1982 is now due to return.
He
says autumn and winter periods failed to deliver enough rain to
establish crops, meaning the growing season never got under way in
many regions.
When
Jupiter and Saturn are closest together – which will occur next
year – it will have a minimising effect on Australia’s rainfall,
Mr Long claims.
‘In
the last 50-100 years these two cycles have moved closer and closer
together and have finally synchronised,’ Mr Long said.
‘This
synchronisation will then have a greater effect on our rainfall.’
The
period 2019-2021 is very likely to be the driest period in the
Australian climate for over 200 years.
With
all of NSW being declared drought affected earlier this year, Mr Long
said that there will be a significant impact on crops.
‘There’s
hardly a crop between the northern and southern border in NSW,’ he
explained.
‘That
represents about a third of the eastern half Australia’s food
production.
‘Half
of Queensland is in similar situations and the north western half of
Victoria is the same.
‘I
don’t think there’ll be any profitable crops grown in half of the
Murray Darling Basin this year and the rest of it is going to be very
poor.’
Areas
which did receive a significant amount of rain will have very low
soil moisture if they experience a couple of weeks without any decent
rain.
Extended
periods of dry weather during spring will greatly increase the risk
of damaging crops, like the ones that have just occurred during the
last week of winter.
Shocking
figures revealed that parts of Victoria have lost a third of their
usual amount of rain.
‘Victoria
had the wettest decade in 1970 at 627mm average. In the 1980s the
average rainfall was 572mm. The 1990s saw 536mm, while 2000/09
experienced 418mm,’ Mr Long said.
The
Bureau of Meteorology announced the odds of an El Niño system
forming this year are now twice as high as normal.
El
Niño events often result in severe droughts, bringing higher
temperatures, lower than average rainfall and increased risk of
bushfires.
The
phenomenon could last as long as two years.
If
an El Niño does form in the latter half of 2018, it could prove
catastrophic for parched Australian farmers.
