Politically-motivated manufacture of scientific consensus corrupts the scientific process and leads to poor policy decisions

For over three decades, the reduction of CO₂ emission was the primary motivation for promoting the transition from fossil fuels to alternative energy sources. Concerns about the inevitable exhaustion of fossil fuels were considered particularly during energy crises, but these concerns died out quickly as discoveries of new fossil fuel reserves such as the shale revolution in the US that appeared to secure energy supplies.

This post features a chapter from my new book Solving the Climate Puzzle: The Sun’s Surprising Role.  The book provides a large body of evidence supporting that changes in the poleward transport of heat are one of the main ways in which the planet’s climate changes naturally. It also shows that changes in solar activity affect this transport, restoring the Sun as a major cause of global warming.  Since climate models do not properly represent heat transport and the IPCC reports completely neglect this process, this new hypothesis will not be easily dismissed. I am sure that over time it will lead to a better understanding of how the climate changes naturally, and hopefully less climate hysteria.

As explained in my new eBook, Climate Change: A Curious Crisis, the climate change ‘debate’ has long-since become a Manichaean, deeply polarized, ‘you are either with us or against us’ war of words in which both sides accuse the other of being closed-minded and refusing to accept the ‘facts’.

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

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.

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.”
