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.

The Science Behind Peter Ridd’s Dismissal

A new paper from Dr Jennifer Marohasy has tackled four big myths that have taken hold in Great Barrier Reef research, and in so doing has highlighted the importance of the criticisms of that research made by Peter Ridd. According to Dr Marohasy, a Senior Fellow at the Institute of Pubic Affairs, academic freedom will be the central issue at

Fighting For The Truth About The Reef

Fighting For The Truth About The Reef

It is an injustice that turtles are blown up in the Gulf of Mexico because American oil companies choose a particular and inappropriate method for undertaking surveys before setting explosives. If they did underwater, rather than aerial surveys, it would be difficult to ever justify blowing up biological diverse artificial reefs that are old spent oil rigs. It is also

Know Your Plates (Part 1)

Reef building hard corals in the order Scleractinia are animals that could be mistaken for plants. One of the most common such corals at the Great Barrier Reef is Acropora hyacinthus. At Myrmidon reef last December, we found ridges replete with these plates in various colours including brown and green. A ridge of plate corals, photographed by Stuart Ireland at Myrmidon

Who Ate the Green Plate?

Who Ate the Green Plate?

I wasn’t the one who took that bite out of that green plate coral. Can you see what looks like a bite mark? It is at about 4 o’clock on the large, green, plate coral, which is also one of the transect photographs taken last week, on 22nd February at Pixie Reef by Leonard Lim. Corals one metre along what

Coral Reef Study Program

I’m beginning a program of study that considers coral reef health from three different perspectives: coral colour, percentage cover, and also coral species biodiversity. I’m also interested in the oldest Porites and would like to begin an inventory of them, I’ve already named my largest so far Porites Craig. NB: This post replicates the Coral Reef page at Jennifer Marohasy’s blog, first

Fly-Past Coral Surveys

This morning, Peter Ridd’s legal team will be asking the High Court to hear his appeal against his sacking by James Cook University. The High Court does not agree to hear most cases. They consider cases that have a wider legal implication. His legal team continue to focus on the academic/intellectual freedom clauses in most university enterprise agreements and on

Measuring Old Corals & Coral Reefs (Part 1)

Measuring Old Corals & Coral Reefs (Part 1)

Fundamental to science is measurement. It is a way of objectively assessing something, anything, even the state of a coral reef, even of an individual coral. Historically coral growth rates were measured by coring the really old massive Porites. A shutterstock photograph of coring a massive Porites, shutterstock_677259715 Like tree rings in temperate forests, the massive old Porites can be

Scientists All At Sea With Alarmist Barrier Reef Warning

A new scientific paper, received with great fanfare among inter­national media and Australia’s public broadcaster, the ABC, claims half the corals of the Great Barrier Reef are dead. The paper is by academics at James Cook University’s ARC Centre for Excellence for Coral Reef Studies. It is a scary headline. But is it true? This finding is not based on

Unprecedented Panic Over Bushfire Impact

Unprecedented Panic Over Bushfire Impact

The word ‘unprecedented’ is often applied to des­tructive climate-related events, as though they could not have been predicted, and have never happened before. Last summer’s bushfires were no different. But were they really unprecedented? This narrative creates anxiety because it follows that there really is a climate emergency and that we have pushed nature out of ­balance. Appearing as a

Great Barrier Reef Platitudes: More Dangerous Than Sharks

It has always been the case that the individual is expected to conform and that there is hierarchy within myths. Myths are of course traditional stories, often explaining a natural phenomenon typically involving supernatural beings or events. Of course, most people, most of the time, are so emersed (and kept so busy) within the established hierarchy and the myth, that
