THE hubris of the Australian Bureau of Meteorology is on full display with its most recent remodelling of the historic temperature record for Darwin. The Bureau has further dramatically increased the rate of global warming at Darwin by further artificially lowering historic temperatures. This begins by shortening the historical temperature record so that it begins […]| Jennifer Marohasy
The Intergovernmental Panel on Climate Change (IPCC) has an idea about how the Earth cools itself: when the planet’s surface warms up, it sends more heat into space as infrared radiation. They estimate that for every 1-degree Celsius increase in temperature, the Earth releases an extra 3.3 watts of energy per square meter—a natural cooling […] The post Complicating the IPCC Planck Feedback, Plank #4 of Climate Resilience Theory appeared first on Jennifer Marohasy.| Jennifer Marohasy
Stand on a seaside shore, watch the tide roll in and out, and I can see, and feel, the Moon’s force, cyclical, ever present and yet not easy to unravel. There are now tide times, that accurately forecast the height of sea level for any location on Earth. Not the same, ever changing, yet able […]| Jennifer Marohasy
We all know the story about the king who paraded with no clothes, as though everyone watching on was oblivious to the mistake. Parallels can be drawn with sources of CO2, I mean CO2 from factories versus CO2 from natural sources. There is no definitive distinguishing feature, yet in this case we are expected to […] The post How Climate Works. In Discussion with Philip Mulholland about Carbon Isotopes appeared first on Jennifer Marohasy.| Jennifer Marohasy
I was chatting with a friend on Friday, about the various dynamical state variables, as opposed to external drivers, that might need to be incorporated into my new Theory of Climate Resilience. Ultimately, I want a quantitative model, that can test various hypotheses including that the tropical Pacific Ocean never gets particularly hot — never […]| Jennifer Marohasy
I’m sometimes asked how ocean circulation can naturally cause global warming, with many assuming solar variability or under sea volcanoes to be the indirect immediate cause. My New Theory of Climate Resilience will focus instead on ocean upwelling dynamics, particularly in the Eastern Equatorial Pacific (EEP), and their modulation by lunar cycles. And I’m thinking […] The post How Climate Works: Upwellings in the Eastern Pacific and Natural Ocean Warming appeared first on Jennifer Maroh...| Jennifer Marohasy
Conventional thinking treats ice primarily as a consequence of climate change: when the planet cools, ice grows; when the planet warms, ice melts. Alex Pope has convinced me that this view is mostly wrong. Furthermore, Alex’s somewhat radical hypothesis fits neatly into my New Theory of Climate Resilience, including through our shared focus on the […] The post How Climate Works.

Carbon dioxide is indeed the ‘stuff of life’, underpinning photosynthesis, boosting plant growth, enhancing agricultural yields, and enabling practical applications in industry. While discussions so often focus on its role in climate change, CO₂’s contributions to life in ecosystems is profound and undeniable, making it a cornerstone of biological and other planetary processes. CO₂ is […] The post Oceans Giving Back a Little C02. The Good News from Bud Bromley’s Zoom Webinar on ...| Jennifer Marohasy
Tesla had a 71% drop in first quarter profits compared to last year, but those losses were minimised because they picked up $595,000,000 US in regulatory credits for the quarter. Indeed, according to Tesla’s Q1 2025 earnings, net income fell 71% to $409 million from $1.39 billion the previous year, driven by a 13% drop […] The post The Electric Car Rort appeared first on Jennifer Marohasy.| Jennifer Marohasy
Before climate science became ‘settled science’, there were various theories suggesting that because the amount of carbon dissolved in the Earth’s oceans exceeds that in the atmosphere by about a factor of 60, the atmospheric CO₂ content must be dictated by the chemical state of the oceans. We don’t hear so much any more about […]| Jennifer Marohasy
Pope Francis’s death marks the end of a papacy that boldly thrust the Catholic Church into climate change politics, most notably through his 2015 encyclical Laudato Si’. His fervent advocacy, framed as a moral imperative to save “our common home,” reshaped the Church’s role in global debates, and at a cost. By leaning on institutional [...] The post Vale Pope Francis: A Legacy of Faith Over Facts appeared first on Jennifer Marohasy.| Jennifer Marohasy
Before the advent of computer simulation modelling and the Intergovernmental Panel on Climate Change (IPCC), the past record of climate change was assembled from a variety of different types of evidence including chronicles, grain price records, radiocarbon dating, pollen analysis and vegetation history, tree rings, ocean bed deposits as well, of course, as meteorological instrument […]| Jennifer Marohasy
I’ve never met someone who denies that the climate changes. The issue for so called ‘sceptics’ tends to be how much of the recent warming might be natural, as opposed to human-caused. Then there are those who profess to care deeply about our natural wonders, including the Great Barrier Reef, but only from a […]| Jennifer Marohasy
One of my interests is in understanding how and why the climate is so stable, for sure it has been over the last several thousand years. Where I live, on the Tropic of Capricorn, daily atmospheric temperatures may fluctuate by 20C, yet the seasonal variation in sea temperatures is less than 10C and if there […]| Jennifer Marohasy
