Australia has had megadroughts for the last thousand years says ice core study

A new study of Law Dome Ice cores tells us that droughts are common in Australia, and that there appears to be eight mega-droughts over the last thousand years, including one that lasted a whopping 39 years from 1174- 1212AD. By their reckoning the 12th Century in Australia was a shocker with 80% of it spent in drought conditions. Things weren’t so bad from 1260 – 1860, at least, as far as they can tell. The researchers are convinced theirs is the first millennial-length Australian drought record. It does seem significant.

The researchers, sensibly, think we might want to pay attention to the Pacific cycles and store a bit more water. Without fanfare the paper also suggests that droughts were worse in medieval times.

“This work suggests Australia may also have experienced mega-droughts during the Medieval period that have no modern analog. Therefore, management of water infrastructure in eastern Australia needs to account for decadal-scale droughts being a normal feature of the hydrological cycle”…

    First the drought came, then the rains stopped …

    Someone will find a way to blame it on Global Warming.

    Archaeological evidence shows that the Australian continent used to be tree-covered. The trees set up a water cycle that kept the rains coming. The loss of the trees – possibly due to the Aboriginals burning them down – stopped this water cycle and led to the creation of a barren interior. It may be possible to reverse that process one day.

    We can fairly and accurately lay the responsibility for the paucity of water storage in NSW Australia at the feet of N K Wran as he tried to marry Green/environmental support to the ALP. In NSW Wran was successful in organising this marriage to the everlasting detriment of NSW. Thank you Nifty and the NSW ALP.

      Yep, although there is talk now of building several new dams. The green tide may have receded.

        Even the environmentalists agree there is no science only Allah.
