Global warming linked to south-east rainfall decline
1/05/2008 3:53:00 PM
There is growing evidence that lower rainfall and reduced runoff in the 
south-east of Australia is linked to global warming.
That's just one of the findings discussed at a science review for land and 
water resource managers organised by the South-Eastern Australia Climate 
Initiative (SEACI) in Melbourne yesterday.

SEACI, which began in 2006, is a three-year, $7 million collaboration 
between six agencies to provide the most intensive analysis yet of factors 
responsible for the rainfall decline over the past decade and inflows into 
the Murray-Darling river systems.

The Murray-Darling Basin Commission is the managing agency of the program.

MDBC chief executive,Wendy Craik, said Bureau of Meteorology and CSIRO 
research for SEACI had generated increasing evidence of the impacts of 
global warming on rainfall in the south-east of Australia.

"The research shows there are firm signals in the current drought that 
correlate with future projections of reduced rainfall in southern 
Australia," Dr Craik said.

"It also provides evidence of a clear north-south rainfall divide on either 
side of a naturally-occurring band of high pressure (known as the 
sub-tropical ridge) roughly on a line running east to west through Adelaide 
and Canberra."

Dr Craik said the Melbourne meeting also discussed SEACI's work on an 
extensive review of a century of rainfall and temperature records and a 
refinement of climate models to deliver localised seasonal forecasts.

COMMENTS:

I think preocupation with the weather is as damaging to the soul as any 
other worry.
Giving thanks is good for the soul so count your blessings and don't dwell 
in the negative or the Black Dog will attack you.

"Increasing evidence" is not proof.
More likely it is scientifically at a great distance from it being proven to 
be man-made.

Climate changes in our lifetime.

There is nothing unusual about climate change.

Climate stagnation would be odd.

The set up is from the left to get us all to stop using petroleum products 
and crater our prosperity and that of the entire world.

I don't believe the jet-stream is moving north, putting high pressure 
systems over the south and midwest causing droughts.
I don't believe in those wildfires being a full order of magnitude larger 
than previously measured by the fire fighters.

Without forest fires, where could they find jobs?

I do not believe the methane blooms off the coast of Africa which are 
dumping methane into the atmosphere at alarming rates are because of 
over-fishing.

I don't believe in the droughts in the midwest last year and the crop loss 
that occured.

I don't believe that auto emmissions starting back in the '60s had anything 
to do with the decades long drought in the Sahel.

I don't believe air pollution darkens the sky.

I don't believe the pac norwest salmon fishing is shut down this year.

I don't believe the photos of the Larson B ice shelf calving or any of the 
myriad of photos showing glaciers evaporating.

I don't believe the glacial lakes drained overnight.

I don't belive in dead-zones around all continental shelves.

I don't believe the cost of gasoline is rising from increased demand.

I don't believe that global dimming from particulate pollution as measured 
by Ramanathan over the Maldives occured, nor is the pan evaporation rate 
declining world-wide as measured by farmers in the same pan for the last 
century.

I instead believe in God, something completely lacking any scientific 
evidence and based solely on humans from two centuries ago who believed that 
they heard voices.

I am going to go turn my car on in the garage with the door shut and pray 
for all of you warmers.

I also don't believe there is a place called Australia.

Prove it.

I have been involved with agribusiness for over 40yrs and am well aware of 
the reduction in rainfall in eastern Australia over the last 10 yrs.
But there is evidence that this has happened before and then we had wet 
periods.

Change both ways, does happen.

But come to think avout it I haven't seen any Dinosaurs about lately.
