During my time at Legal Insurrection, I have stressed the importance of viewing climate through the scope of geologic history. For example, I have done posts on “extinction-level events” throughout history.
Norwegian scientists recently did the same thing, comparing global temperatures with carbon dioxide (CO2) levels. The researchers conducted statistical analyses of observed and reconstructed temperature series and tested whether the recent fluctuation in temperatures differs systematically from previous temperature cycles, potentially due to the emission of greenhouse gases.
For example, the researchers gathered all the data from various sources, including those related to the four previous glacial and inter-glacial periods. They did a statistical analysis to see how more recent Global Climate Models (GCMs) compare.
They concluded that there was no way to link man-made carbon dioxide levels to climate change.
[T]he results imply that the effect of man-made CO2 emissions does not appear to be sufficiently strong to cause systematic changes in the pattern of the temperature fluctuations. In other words, our analysis indicates that with the current level of knowledge, it seems impossible to determine how much of the temperature increase is due to emissions of CO2.
But I was unprepared for The Washington Post to do the same thing, accidentally admitting that the Earth is at its coolest temperatures in 485 million years.
Granted, the article was intended to push the climate-emergency narrative.
An ambitious effort to understand the Earth’s climate over the past 485 million years has revealed a history of wild shifts and far hotter temperatures than scientists previously realized — offering a reminder of how much change the planet has already endured and a warning about the unprecedented rate of warming caused by humans.The timeline, published Thursday in the journal Science, is the most rigorous reconstruction of Earth’s past temperatures ever produced, the authors say. Created by combining more than 150,000 pieces of fossil evidence with state-of-the-art climate models, it shows the intimate link between carbon dioxide and global temperatures and reveals that the world was in a much warmer state for most of the history of complex animal life.
But looking at the full picture, I believe people will find it hard to be afraid of global warming, given that the Earth is at historically cold levels.
The Science article from which The Washington Post takes its information is here for those who wish to review it. Interestingly, one of my early works as a geology student was looking at oxygen isotopes to estimate ancient temperatures (one of the tools to reconstruct surface temperatures).
Clearly the publication stresses the role of carbon dioxide in Earth’s temperatures:
“This research illustrates clearly that carbon dioxide is the dominant control on global temperatures across geological time,” said Jessica Tierney, a paleoclimatologist at the University of Arizona and a co-author of the new paper. “When CO2 is low, the temperature is cold; when CO2 is high, the temperature is warm.”
Even if that is true, and I have my doubts, then increasing the levels of the life-essential gas should be a good thing.

Arguably, the Earth can be considered in a C02 famine:
Finally, it’s good to remember none of the climate-hysteria predictions have come true.
