Our speaker on Tuesday October 20th was Dr Phil Eberbach, CSU Associate Professor, School of Agricultural and Wine Sciences.  The title of his presentation was Regional trends in rainfall: climate change or normal variability.  Some of the main points of Dr Eberbach's presentation were:

Three major climate drivers affecting the climate of SE Australia

  1. El Nino Southern Oscillation
  2. Indian Ocean Dipole
  3. Southern Annular Mode (SAM)
Is this shift in GSR (Growing Season Rainfall) climate change?
  1. There is a change in winter rainfall patterns to the south of Central NSW 
  2. Is the change part of a cycle?
  3. Possibly but not according to the models
Summer rainfall appears un-affected?
He included in his presentation a summary of projections from the Victoria Department of Environment, Land, Water and Planning 2019 (DELWP).  Victoria's Climate Science Report 2019 brings together the latest climate change science knowledge gained from the Victorian Government's ongoing investment in climate science, the Victorian Climate Projections 2019.
There were a number of questions throughout Dr Eberbach's talk as the subject is of concern to all.  
President James presented Dr Eberbach with a gift from the club and gave a vote of thanks on behalf of all the members.
