I discovered this historic BoM (1999) flyer while searching for a hard copy of a 1992 paper on the 1970’s Pacific Climate Shift. Read how the BoM attributes – El Nino – thousands of years of ice ages and warm periods – solar cycles – volcanic eruptions – oceans and currents – sea-ice extent – greenhouse and on the back page urbanisation and land use changes get a nod. Page one – two – three – four.
I found on my HDD this front page of Kerr R.A. 1992. Unmasking a shifty climate system. Science 255: 1508–1510. – if anybody has a pdf please pass on. Three of the time-series charts in BoM 1999 – temperature – rainfall and cloud cover all show evidence of a shift in the 1970’s.
I sourced updated data for the Pacific Decadal Oscillation (PDO) from NOAA and made this monthly PDO chart 1854 to current. Positive periods tend to be dry and negative wet.
We should recall the Qld DPI very useful rainfall maps that I blogged on in March 2018. They have more versions now.

Australian economy in 1 chart
Resource exports still booming skywards with the rest far far behind.
Resource industries have little political pull, put up with constant denigration by media, greenleft and sundry, while the rural sector floods our parliaments and often has their hands out for taxpayers money for this or that reason. Mines occupy a minute area of Australia compared to vast areas covered by agriculture and pastoral.
NIWA failed Outlook hours before SW NZ deluge
Days after publishing their “climate Outlook” NIWA’s work is demolished by a damaging biblical deluge NIWA was too incompetent to see coming. Hilarious – yet these taxpayer funded leech Climate orgs have any status left?
