WA drought 'could be worst for 750 years'

Scientists have made a surprising link between climate patterns in Australia and Antarctica.

 

Since the 1970s, there has been a decline of up to 20 per cent in winter rainfall in the South-West and, though the cause of the drought remains unclear, others have pointed to land-use changes, ocean temperatures, air circulation changes and natural variability.

But its severity has been hard to calculate, with weather records going back only about 100 years, and the oldest tree-ring record, 350 years, from a site that has not been affected by the drought.

Yes, lets not get too overly dramatic Chalpat! 750 years huh? Nice way to sensationalise a story!

Will those people that advocate for climate change politics please stick to facts? They expect everyone else too!
