Jennifer Marohasy

Senior Fellow

Jennifer Marohasy is a Senior Fellow with responsibilities for Climate Change in the Research Program at the IPA.

Dr Marohasy has published in prestigious scientific and law journals over the last few years, these have included: Atmospheric Research, Advances in Atmospheric Research, Wetlands Ecology and Management, Human and Ecological Risk Assessment, Public Law Review and Environmental Law and Management. She has also written for various newspapers and magazines including The Australian, The Courier Mail, The Herald Sun, and for ten years was a fortnightly columnist for Fairfax Media’s rural flagship, The Land. Dr Marohasy remains a regular contributor to e-journal On Line Opinion.

Dr Marohasy first worked for the IPA between 2003 and 2009; writing a seminal paper that showed rising-salinity in the Murray River was contrived – a product of computer modelling. Actual salinity levels had been falling for over 20-years as a consequence of successful government-sponsored drainage management programs in irrigations areas.

Between 2009 and 2015 Dr Marohasy was involved with various university research programs. Her re-appointment at the IPA in August 2015 followed the termination of an adjunct position at Central Queensland University following the ousting of Bjorn Lomborg from the University of Western Australia. Her work at CQU was wholly funded by the B. Macfie Family Foundation, and this continues to be the source of funding for her employment at the IPA.

Dr Marohasy describes herself as a utilitarian libertarian: she much prefers appeals to reason, logic and evidence over authority and consensus.
