CLIMATE CHANGING PLANTS

Taller, Now Our New Climate’s Thickening their Leaves

High CO2 levels cause plants to thicken their leaves, could worsen climate change effects,
University of Washington, October 1, 2018.

MAIN POINTS

Physical Effect
“...scientists have observed that when levels of carbon dioxide in the atmosphere rise, most plants do something unusual: They thicken their leaves.”

Systematic Effect
“...would be less efficient in sequestering atmospheric carbon, a fact that climate change models to date have not taken into account.”

When
“...under the high atmospheric carbon dioxide levels expected later this century...”

Effect
Thick-Leaf Loss of Plant CO2 Squester
“...leaving about 5.8 extra petagrams, or 6.39 billion tons, of carbon in the atmosphere per year.”

Scale of Squester Loss
“Those levels are similar to the amount of carbon released into the atmosphere each year due to human-generated fossil fuel emissions — 8 petagrams, or 8.8 billion tons.”

The Bottom Line

Loop
It is apparent that increasing atmospheric temps rising far above our average baselines, are first, releasing greenhouse gases that would normally remain bound-up in our environment, which are increasing temperatures further, which have subsequently risen enough to release a whole range of greenhouse compounds.

Our CO2 release is reinforcing itself, and multiplying its own effect, by trigger further releases.

Food of the Loop
This feedback loop is threatening to become, if it has not already become, a self-perpetuating cycle of release, more heating, and yet more releases, until all potential CO2 available to both of our, “systems,” being our planet’s CO2 system, and our, “civilization’s,” system of energy production and consumption, is all in the atmosphere.

Spiraling Loop
I believe we’ve already passed that certain level of atmospheric CO2 at which our planet will be assured of going ice free, while our atmospheric CO2 situation twenty years ago already ended the cycle of Ice Ages that’s characterized the last few million years of our planet’s history. Continuing with further CO2 emissions beyond this point puts us at risk of a Venus-style greenhouse effect.

It’s Here Now, or Near
This research tells us by the latter part of this century plants alone will lose the ability to squester as much carbon as we humans produce today. That means we will be involved in, and be aware, that we are in a, “runaway,” greenhouse scenario, likely by the middle of this century, at the latest.

No Worries. Most of the plants won't make it to that point...

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!
