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.

Rewriting Australia’s Temperature History

This post provides a link to download as a PDF, Chapter 16 of Climate Change The Facts 2020, “Rewriting Australia’s Temperature History”, by Jennifer Marohasy. The Bureau of Meteorology is one of Australia’s most important national public institutions; so much depends on our knowledge of past climate and our ability to predict future trends and events.

Revealed: The True Hottest Day Ever Recorded In Australia

The Australian Bureau of Meteorology deleted what was long regarded as the hottest day ever recorded in Australia, Bourke’s 125°F (51.7°C) on Sunday, January 3, 1909. This record* was deleted, falsely claiming that this was likely some sort of ‘observational error’, as no other official weather stations recorded high temperatures on that day. However, the Liberal Member for Hughes, Craig

How Badly Have Environmentalists Misled And Frightened The Public!

Once too scared to speak out, finally, Michael Shellenberger, is explaining some inconvenient facts about environmentalism and how it is hurting our Earth in a new book published by Harper Collins. In a synopsis Shellenberger articulates what I have known for so long: ● The most important thing for reducing pollution and emissions is moving from wood to coal to petrol to natural

Not Running Out Of Oil, Or Sunshine

I remember through the 1970s, we were meant to run out of oil, soon. In fact, as long as I can remember we have been running out of oil, soon. Instead, oversupply is such that the benchmark for US oil fell below zero for the first time ever a couple of days ago. That is, the share market suggested oil

Coral Catastrophes Imagined

Exactly one year ago yesterday,* I was getting off a train in Proserpine, looking to pickup a hire car to drive to Bowen. I wanted to know if the coral there was all dead, or not. Bowen is a coastal town in North Queensland, not far from Abbott Point that is the coal terminal for the controversial Adani coal mine.

Running Out Of Rice, While Wasting Water

Australia was once self-sufficient in rice. We now grow less than 25 percent of domestic rice consumption. The SunRice Group has been importing rice from Vietnam and repackaging it to make-up the shortfall. Since the Corona Virus pandemic, the Vietnamese government has banned the export of rice, while the Australian Bureau of Meteorology has feigned an unprecedented drought. There is a need

Warming Marble Bar

MY friend Craig Kelly – the Federal member for Hughes – attempted to raise the issue of the world’s longest heat wave record in the Australian parliament last Wednesday. He was shut down by Tony Burke, the manager of opposition business. Specifically, Mr Kelly was attempting to draw attention to how the historical observations have been changed, and how the

Cooling the Past: Made Easy for Paul Barry

It is not disputed that Blair Trewin under the supervision of David Jones (both working at the Australian Bureau of Meteorology) remodel all the historical temperature data generating trends and statistics that look quite different from the actual measurements. The remodelled series are then passed on to university and CSIRO climate scientists who base much of their climate research on
