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.

Hyping Maximum Daily Temperatures (Part 4)
John William Abbot versus Director of Meteorology was to be heard in the Administrative Appeals Tribunal, Brisbane, yesterday, Friday 3rd February 2023 – a focus of this series of blog posts. While it was to be a public hearing, and I was to be the expert witness, before I could present my evidence, the case was taken back into mediation and

Hyping Maximum Daily Temperatures (Part 3)
If maximum temperatures are the same, whether measured by platinum resistance probes or mercury thermometers, why does the Bureau make an adjustment of 0.5 °C in the homogenisation of temperatures from Cape Otway Lighthouse? ACORN-SAT is the temperature database derived from the ADAM database, used to report on climate change trends. This is an extract from the Bureau’s ACORN-SAT Station

Hyping Maximum Daily Temperatures (Part 2)
Available Australian Bureau of Meteorology parallel maximum temperature data for Mildura – temperatures recorded from both a mercury thermometer and a platinum resistant probe on the same day in the same shelter – show no equivalence. They are different. Therefore, it is impossible to reliably compare official temperatures recorded from probes with historical temperatures recorded with mercury thermometers for the

Sea Level Update From Noosa National Park, Queensland Australia
It is repeated, non-stop: glaciers and ice sheets are melting, and so the sea levels are rising. We are all doomed. We will all be drowned, said Hanrahan. So, each year on the highest tide I go see how much the ocean has risen. Each year I go to that rock platform with the wave cut notch expecting to be

Hyping Daily Maximum Temperatures (Part 1)
There is more than one way to ruin a perfectly good historical temperature record. The Australian Bureau of Meteorology achieves this in multiple ways, primarily through industrial scale remodelling (also known as homogenisation – stripping away the natural warming and cooling cycles that correspond with periods of drought and flooding), and also by scratching historical hottest day records, then there

Happy New Highest Tide For 2023 – Sunday 22nd January
Shout out to Bruce Davidson! I am planning to be in Noosa on Sunday, January 22nd for the highest astronomical tide for the year. I will dust off Skido (my drone) and get some more photographs and video of the ever-changing sea levels. Everyone is welcome! The plan is to meet at Boiling Point Lookout, Noosa National Park, at 7.32 am. The

Fear, Flooding, Forecasting & Australia’s 2022 Official Rainfall Statistics
This year the Australian Bureau of Meteorology waited until after close of business on Friday 6th January 2023 to release the official climate statistics for 2022. After claims of unprecedented extreme rainfall all year, the statistics must be disappointing for those animated by the idea of a climate catastrophe: Nationally averaged rainfall was [just] 25% above the 1961–1990 average at 582.2

BOM Buries Record Daily Rainfall During Lismore Floods
The NSW Premier handed down the 2022 Flood Inquiry report last week and at the same time many of the 1,498 written submissions were made public. The submissions make for harrowing reading, especially the first-hand accounts from the Lismore community. There are very personal stories explaining how there had been limited flash-flooding up to 27th February. On that Sunday some thought the

Good News About Corals – As Legislation Introduced To Devastate Farming
It is no coincidence that the latest Australian Institute of Marine Science (AIMS) report claiming record high coral cover was released on the same day the net zero legislation passed the lower house of the Australian Parliament, on 4th August 2022. In March, AIMS was claiming more than 90% of the Great Barrier Reef (GBR) to be severely bleached. That

Latest Survey Of ‘Coral Cover’ Fundamentally Unscientific
According to the latest Australian Institute of Marine Science report, there is record coral cover at the Great Barrier Reef. Yet this is less than 30 percent at about half of the reefs surveyed. The relatively low percentage cover is because only the reef perimeter is surveyed by AIMS, which is the equivalent of reporting on the population of Sydney after
