This report brings readers up-to-date with happening in the Australian generation industry since the previous posts: Australian Renewables Integration: Part 1, Part 2, Part 3. While many were optimistic about Australia’s planned changes, we were concerned that technical problems would emerge and that the costs of the transition will also make the power significantly more expensive for a less reliable supply.

A deep dive into the causes of the unusual weather/climate during 2023. People are blaming fossil-fueled warming and El Nino, and now the Hunga-Tonga eruption and the change in ship fuels. But the real story is more complicated.

In 2007, two Canadian scientists studying the effects of this cycle on the Pacific coast of North America successfully predicted the occurrence of a major El Niño event in 2015 based on lunar data. Remarkably, their prediction proved accurate.

My book ‘The Grip of Culture’, subtitled ‘The social psychology of climate change catastrophism’, is now published.
“Climate change catastrophism is a cultural disease haunting Western society. Andy West’s excellent study of this problem explains the different drivers of this disease. It is an important contribution to a debate where reason must prevail.” – Frank Furedi, emeritus professor of sociology at the University of Kent

In spite of better meteorological technology than ever and more raw scientific knowledge about storms, we are seeing a serious regression in a vital government program: the National Weather Service’s tornado warning program.

Over the past two decades, solar activity has been characterized by an extended solar minimum spanning two solar cycles, known as the Clilverd Minimum. This phenomenon is currently affecting the climate, but before we can understand its impact, we must address the significant discrepancy between the solar effects observed in paleoclimate proxy records and modern observations.

My reflections on the Held v Montana Climate Lawsuit – the inside story, my written expert report and why I didn’t testify at the trial. Don’t believe the PR about this case from Our Children’s Trust, which the mainstream media has accepted uncritically.

I recently published one article about how to incorporate an AI chatbot as part of a college course. I focused on lying, persuasion and self-reflection. I went even further and anticipated a White House comprehensive plan to counter antisemitism. I used a chatbot to develop my own version of what should be in that plan. Now, I am off on another adventure using a chatbot to understand the ins and outs of climate change impacts. And I need your help. You can see my inquiry as similar to the struggle to get computers, other electronic devices and software to be more user friendly — such as the improvements through GUIs (graphic user interfaces). Perhaps AUIs (algorithm user interfaces) would be helpful — especially if users can insert their own parameters (or “biases”) with a preset language formula.

Clintel has published a new report entitled “The Frozen Climate Views of the IPCC: Analysis of the AR6.”
“The new Report provides an independent assessment of the most important parts of AR6. We document biases and errors in almost every chapter we reviewed. In some cases, of course, one can quibble endlessly about our criticism and how relevant it is for the overall ‘climate narrative’ of the IPCC. In some cases, though, we document such blatant cherry picking by the IPCC, that even ardent supporters of the IPCC should feel embarrassed.”

Reflecting on the U.S. response to the covid pandemic, Dr. Fauci provides some important insights on managing complex risks – with relevance to climate change and the electric grid transition.

There are many reasons why grid experts within the electric utility industry have not spoken out when unrealistic “green” goals were being developed and promoted over the last 20 years or so. A more open debate during this period might have helped provide a more realistic foundation for future development. This posting describes some reasons as to why at the corporate level electric utilities did not speak out more in defense of grid reliability. Collectively these factors tended to eliminate grid experts from playing any role in the development of policies impacting the grid.

Much has changed in science since the pandemic and much of it is change for the worse. The pandemic has highlighted the loss of credibility of the public health establishment and the often toxic nature of current public discourse. John Ioannidis stands out as perhaps the best example of a fine scientist who was smeared and denigrated mercilessly both online and in the literature. There was also a flood of fraudulent papers and badly flawed studies. This made claims that we should follow the “The Science” almost laughable, given the extremely poor quality of much of the science. The use of coercion was inexcusable when there was no rigorous basis for it.

I recently published an op-ed in the Financial Post describing the findings of the new JGR paper by NOAA’s Zou et al. NOAA’s STAR series of the MSU satellite-based tropospheric temperatures used to show more warming than UAH or RSS in the mid-troposphere. Zhou et al. recently rebuilt their dataset and now STAR has a slightly lower trend than UAH. This is a big deal because it adds to the evidence that GCMs are warming too much compared to observations, which suggests problems with their climate sensitivity (ECS) values.

“Green” ideas and their proponents can create problems. Like the antagonist in Terminator 2, green arguments and proponents don’t go down easily. With serious challenges, they retreat, hibernate sometimes, morph, transform and come back. It’s hard to argue with many “green” energy ideas. They are often huge in scope but severely limited in details. Focusing on a couple key factors and ignoring or leaving so much to be worked out later. Painfully naïve or unaware of so many factors associated with the provision of energy, feedback and often even human behavior. They see the flaws in current efforts, but are blind to the drawbacks which will necessarily emerge from their proposals. The offer conjectures with a lot of dots to still be connected. They speak of things that may be possible, without any handle on the probabilities.

Do we care more about keeping CO2 emissions lower in just the western world, or do we want to reduce emissions worldwide?

Last week’s Hearing was a sad example of what passes for debate and deliberations by the U.S. Senate. In any event, it provides an interesting case study of why the U.S. cannot bridge the partisan divide and figure out how to deal sensibly with the climate change issue.
