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.

John Brewer Reef – Back To Beige

Just as a team from the United Nations were flying into Australia at the behest of James Cook University Professor Terry Hughes – seeking to have the Great Barrier Reef’s world heritage status downgraded – Adjunct Associate Professor Adam Smith was posing for photographs at John Brewer Reef for The Guardian newspaper. At that time, back on 20 March (2022), the mild bleaching

Rebels to the Coral Reef Cause (Part 5)

The top feature image shows two of the participants in the IPA’s Reef Rebel program in the water.  All the photographs in this blog post were taken at Stanley Reef on 7th July 2022 by Jennifer Marohasy, or on the way to Stanley Reef. One of the participants on the IPA Reef Rebels’ tour said to me earlier this week,

Rebels to the Coral Reef Cause (Part 4)

It was so cold and rainy in Cairns on Tuesday, but it didn’t stop us getting on a cruise boat and going out to Moore Reef, which is part of the Great Barrier Reef. We went on the Sunlover day cruise with about 310 other paying customers. It was blowing a gale and the rain was relentless, but it didn’t stop us

Invitation To The Premiere Of Our New Film – A Coral Bleaching Tragedy

This is Part 3 of a new series: Rebels to the Coral Reef Cause. The Great Barrier Reef has been around in various forms for more than 600,000 years. It has survived fluctuating temperatures and sea levels as ice-ages have come and gone, and Australia has drifted northwards. But is the latest episode of coral bleaching something new and different?

Rebels To The Coral Reef Cause (Part 2)

To the extent that it is possible for any human endeavour to be so, science is value-free. Science is a way of attempting to understand the world in which we live from a rational point of view, based on observation, experiment and tested theory. Irritatingly, especially for governments, science does not operate by consensus and it is often best progressed

Rebels To The Coral Reef Cause (Part 1)

Everybody claims to care about the Great Barrier Reef, but very few people take the time to actually visit it.  The reports of mass coral bleaching this past summer are mostly from aerial surveys flown at 150 metres altitude in aeroplanes and helicopters. I have repeatedly argued that you can’t see very much from that distance. The Institute of Public Affairs have

IPA Report: Are Extreme Rainfall Events Increasing In Frequency?

Torrential rains along the east coast of Australia during February and March 2022 have been blamed on climate change. Specifically, a narrative has developed suggesting that rainfall is becoming more extreme. “The pattern of more intense rainfall events is well established in Australia. In recent decades, the intensity of short duration (hourly) extreme rainfall events has increased by 10 percent.

Highest Tide On Falling Sea Levels In Noosa

I live by the sea and like walking along the coastline including scrambling over the rock ledges in Noosa National Park. All the way from Noosa to Sydney it is possible to find wave-cut platforms etched out of the sandstone towards the bottom of the cliff faces. The sandstone is very old, thought to date from the time of the

Underwater Photographer Fact Checks Scientists “Absurd” 21.8% Coral Cover Claim

The Australian Institute of Marine Science (AIMS) have been tasked with reporting on the state of the corals and coral cover. They surveyed John Brewer Reef in March, made no mention of any coral bleaching in their report, and stated coral cover to be just 21.8%. There are no photographs. Underwater photographer Leonard Lim visited this same coral reef a month

Epicentre of Mass Coral Bleaching – Still So Beautiful (Part 1)

It is all over the news, right across the world: the Great Barrier Reef is bleaching – again.   Children can’t sleep at night: it is not only the war in the Ukraine keeping them awake at night, but also our apparent disregard for nature. Except! On 10th April 2022 I went to the very epicentre of the claimed latest severe mass
