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.

Feeding the Fishes, A$1 Billion

The feature image is the view from a drone up about 120 metres, of me floating above the front of Pixie Reef, an inshore reef just to the north of Cairns.  This reef was categorised by Terry Hughes as badly bleached, flying at about 150 metres and looking out from an airplane window. The Great Barrier Reef is vast: a

Australia’s Broken Temperature Record (Part 1)

The feature image, at the very top of this blog post, shows me at the Goulburn weather station in August a few years back. It could be that the last 26-years of temperature recordings by the Australian Bureau of Meteorology will be found not fit for purpose and will eventually need to be discarded. This would make for a rather large hole

Maori Science Beats Woke Myths

How many of the approximately 30,000 ‘special’ people who are on their way to Glasgow for COP26 know that 78 per cent of the atmosphere is made-up of nitrogen?

Cyclones Downs, Corals Up – Except in Glasgow

Cyclones Downs, Corals Up – Except in Glasgow

It is impossible to reconcile the official statistics and what is under-the-water with the media reporting – including the reporting from Glasgow. There are meant to be more cyclones and less coral, but we have quite the reverse according to the official statistics. It is also making no sense that those who purport to care so much about the Great

Unable to See the Polar Bears for the Snow

The bottom-line is that despite a reduction in sea ice at the North Pole over this same period, there has been an increase in polar bear numbers.

Plain English Lost on the High Court of Australia

Coral reefs can be messy, and so can court cases. And so it is with the case of Peter Ridd, sacked by James Cook University because he exercised his intellectual freedom. The only thing that is neatly settled from this case is apparently ‘the science’, never mind that this is only because anyone who publicly disagrees with it is censored

Bleached From a Distance

I lent my underwater camera (Olympus TG-6) to a dear friend who recently visited Lady Elliot Island at the Great Barrier Reef. She came over last Sunday to return the camera, and to show me some of her photographs. My favourite is of the Parrot fish just beyond the magenta-coloured corals, shared above. Over the ledge the water is deeper,

Knowing All the Species of Coral at Pixie Reef

Everyone loves the Great Barrier Reef, particularly its corals. Everyone knows that a reef has different species of coral. But how many species should an average inshore reef have? How many corals are there at Pixie Reef, which is so close to the city of Cairns. Such inshore reefs are apparently in terminal decline. Flying at 150 metres altitude above

Fussing Over One Degree of Simulation

I was at the Australian National University in October 2018, when the largest supercomputer in the Southern Hemisphere began running the simulations that have now been published as the IPCC’s Assessment Report No. 6 (AR6). It’s being touted as the most comprehensive climate change report ever. It is certainly based on a very complex simulation model (CMIP6). Many are frightened by the
