A Human First

Humankind Did Not Live With a High-Carbon Dioxide Atmosphere Until 1965,
Texas A&M University, September 24, 2019.


"In 1965, Earth's carbon dioxide atmospheric concentrations exceeded 320 parts per million, a high-point never reached in the past 2.5 million years, this study shows."

"Humans have never before lived with the high carbon-dioxide atmospheric conditions that have become the norm on Earth in the last 60 years..."

"According to this research, from the first Homo erectus, which is currently dated to 2.1-1.8 million years ago, until 1965, we have lived in a low-carbon-dioxide environment -- concentrations were less than 320 parts per million..."

"The scientists analyzed soil carbonates from the Loess Plateau in central China, to quantify ancient atmospheric carbon dioxide levels, as far back as 2.5 million years ago."

"Our paleosol-based CO2 estimates are in line with snapshots of early-Pleistocene CO2 retrieved from Antarctic old, blue ice, suggesting that the Earth system has been operating under low CO2 levels throughout the Pleistocene."

Support Tahoe to Whitney

The Tahoe to Whitney Trail Guide and Magazine are walked, written, funded, and supported by my efforts, with the help of kindred spirits and my sister.

We offer valuable Trail Guide, Skills, Weather, News and Analysis.

My goal is to get you out to see your natural and social potential. Help me keep this unique resource accessible and expanding towards its potential. We've a lot of miles to cover ahead...

If you feel these efforts are valuable, I'm cordially inviting you to support them, here:



I am currently working towards publishing the completed guide between Tahoe & Yosemite as an e-book, while converting this "blog" to a fine magazine format. You will like the results! Help Tahoe to Whitney reach its potential!
