Greatest CO2 Levels in All Human History

 

ECOCRASH NEWS: UNPRECEDENTED MODERN CO2 LEVELS

A Human First

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

MAIN POINTS

"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."

Computer Model: More CO2 than ever before in 3 million years

 

ANTHROPOCENE-CRASHING CLIMATE & ECOLOGY

Breaking Out of Nature’s Boxes:
The Past Shows Big Trouble Ahead

More CO2 than ever before in 3 million years, shows unprecedented computer simulation,
Potsdam Institute for Climate Impact Research (PIK), April 3, 2019.

MAIN POINTS

Ascertained
“...coevolution of climate, ice sheets, and carbon cycle over the past 3 million years.”

Big Human Changes
“CO2 greenhouse gas amounts in the atmosphere are likely higher today than ever before in the past 3 million years.”

It Matters
“...we can now show in computer simulations that changes in CO2 levels were a main driver of the ice ages, together with variations of how the Earth's orbits around the sun, the so-called Milankovitch cycles.”

“...a strong sensitivity of the Earth system to relatively small variations in atmospheric CO2. As fascinating as this is, it is also worrying.”

Beyond Nature’s Limits
"It seems we're now pushing our home planet beyond any climatic conditions experienced during the entire current geological period, the Quaternary."

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...

I NEED HELP!
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!
