This is a little post for the people who subscribed because of the Carbon Dioxide Narrative series. Thank you. The graph below was published in The Washington Post on 19th September 2024, in the article “Scientists have captured Earth’s climate… more »

Preamble After many (I wish I had logged) research and writing hours, 16, 000+ words, 70+ images and six posts later (seven including this one), I could easily end this little mini-series with the same sentence with which it began: TL;DR There’s… more »

Introduction Part 3 of what turned out to be a mini-series (! this wasn’t the intent!) covered the real reason behind Earth’s temperatures past and present — the Sun. This massive object is almost 99.9% of the total mass of the Solar System,… more »

Introduction Let us revisit Dr Soon, and two more slides from that brilliant talk. As with the previous posts, the screenshots below are direct links to the timestamp they were taken at, for people to view more detail if they wish. Please take the time… more »

Introduction Part 3 on the Sun and climate is coming — slowly! — but in the meantime I just had to include a snippet from this most timely two-year-old talk by Dr Willie Soon which came my way just recently (thanks Phil!). Dr Soon’s entire talk is… more »

Introduction There are four major spheres of Earth: the atmosphere (air), the hydrosphere (water), the lithosphere (land), and the biosphere (life). The vast bulk of ‘climate change’ science concerns fields within the first three, which are… more »

The Great Global Warming Swindle Documentary Breakdown This post is a breakdown of Martin Durkin’s documentary The Great Global Warming Swindle, which first aired on the UK’s Channel 4 on 8th March 2007. I chose this film for its broad… more »

TL;DR There’s no global warming spiralling out of control, and our climate is predominantly driven by the Sun. Preamble I didn’t really want to write any of this, to be honest. The whole subject of carbon dioxide (CO2) is… more »

Earth’s Atmospheric Carbon Dioxide (CO2) Concentrations Over Time The previous post covered the fall of atmospheric carbon dioxide (CO2) from 97% [970,000 parts per million (ppm)] 4.5 billion years ago, to around 0.4% (4,000 ppm) 500 million years… more »

Last week’s post on the stroma was a prelude to posts-to-come on the light-independent reactions of photosynthesis. These reactions are the Calvin Cycle, in which the inorganic carbon in carbon dioxide (CO2) is ‘fixed’ into organic… more »
