Climate Etc.

by Nicola Scafetta

My new paper  demonstrates that realistic emissions scenarios and climate sensitivity values & scenarios of natural climate variability produce more realistic, non-alarming scenarios of 21st century climate.

I have a new paper in the peer-reviewed journal Environmetrics discussing biases in the “optimal fingerprinting” method which climate scientists use to attribute climatic changes to greenhouse gas emissions. This is the third in my series of papers on flaws in standard fingerprinting methods: blog posts on the first two are here and here.

“Working in global energy and development, I often hear people say, ‘Because of climate, we just can’t afford for everyone to live our lifestyles.’ That viewpoint is worse than patronizing. It’s a form of racism, and it’s creating a two-tier global energy system, with energy abundance for the rich and tiny solar lamps for Africans.” – Kenyan activist and materials scientist Rose Mutiso

“To deny the developing world access to the very infrastructure that has propelled us forward, all in the name of an uncertain future, is not environmentalism, but neocolonialism masquerading as virtue.” – Earth Scientist Matthew Wielicki

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
