Let the Past be Our Guide? I Hope Not...

Ancient climate change triggered warming that lasted thousands of years,
Penn State, January 22, 2019.

MAIN POINTS

Why PETM Lasted So Long
“...new evidence of a climate feedback that could explain the long duration of the Paleocene-Eocene Thermal Maximum (PETM), which is considered the best analogue for modern climate change.”

Too Late, You Frigging Greedy Fools…
“The findings also suggest that climate change today could have long-lasting impacts on global temperature even if humans are able to curb greenhouse gas emissions. ”

Big-Assed Feedback Loop
"We found evidence for a feedback that occurs with rapid warming that can release even more carbon dioxide into the atmosphere."

Our Future in the Grim Past:
Whoops
"This feedback may have extended the PETM climate event for tens or hundreds of thousands of years. We hypothesize this is also something that could occur in the future."

HOW
Global Warming Extreme Weather
“Global temperatures increased by about 9 to 14.4 degrees Fahrenheit during the PETM, radically changing conditions on Earth. Severe storms and flooding became more common, and the warm, wet weather led to increased erosion of rocks. ”

Erosive Fruits of Extreme Weather
“Increased erosion during the PETM, approximately 56 million years ago, freed large amounts of fossil carbon stored in rocks and released enough carbon dioxide, a greenhouse gas, into the atmosphere to impact temperatures long term.”

“...a warning about modern climate change. If warming reaches certain tipping points, feedbacks can be triggered that have the potential to cause even more temperature change. ”

Trigger, Meet Gun
“...found evidence for the massive carbon release in coastal sediment fossil cores.”

Increased Length of PETM Disaster
“...the climate feedback could have released enough carbon dioxide to explain the roughly 200,000-year duration of the PETM, something that has not been well understood.”

Bottom Line
Ancient Natural Balances/Ecology
GONE
"Today, we're pushing the system out of equilibrium and it's not going to snap back, even when we start reducing carbon dioxide emissions.”

 

 

Earlier Research

“Independent of the causes of the independent inceptions of these disastrous temperature increases, both similar-scale heating "events" will both take about the same time, 100,000 years, to dispel, for "normal" conditions uninfluenced by the disruptions, to return.”

(unless the research atop this page is correct. Then, in that case, it will take 200,000 years of Hell on Earth, for this planet to wash away our effects.)

Thus, I hope the gratifications provided by us eating, of us humans consuming the spirit of life on this planet, were worth it. Was your, "bite of the apple," good?

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!
