Yedoma is Here

Have you heard of yedoma? Outside of those folks that study ice cores and worry about melting permafrost (the fragile layer of frozen soil found in arctic and some subarctic regions) on this planet, most of us would likely have no reason to know anything about it. It is, however, a subject we may want to acquire some basic knowledge about.

In the course of coming up with some ideas for a piece I have to submit in a couple of weeks to the Kansas City Star, I read a couple of articles regarding a study published in the journal Nature, and a European-sponsored project regarding Antarctic "ice coring."

It seems that scientists have been able to get sample ice cores that go back some 800,000 years. Air bubbles trapped within these "cores" can tell scientists the amount of greenhouse gas concentrations over nearly a million-year period. The long and short of it is that carbon dioxide levels are a good deal higher than at any time in 800,000 years.

Possibly even more worrisome is that the increasing melting of the permafrost, especially in Siberia, an area covering some 10 million square kilometers, is not only releasing more CO2 but also Methane. Methane is an especially nasty "greenhouse gas." While methane disperses faster than carbon dioxide, some 10 years versus 100 years for CO2, it is about 23 times more powerful in trapping heat than CO2.

Methane is being released from the permafrost much, much faster than expected. Greenhouse gases and rising temperatures are connected and self-perpetuating: more greenhouse gases mean more melting, leading to increasing amounts of green house gases, and so forth.

Yedoma is a type of permafrost located primarily in parts of Siberia, and mostly lies under lakes. What is of interest here is that the melting permafrost releases methane, whereas under dry permafrost carbon dioxide is released.

In the United States, within two months, Americans will again have another opportunity to break out of their own carefully constructed insane asylum. We will have a chance to change the makeup of the U.S. Congress. Global warming is happening now, and we Americans have another possibility of demonstrating we're not a country of total ignoramuses.

The ice cores tell an interesting tale, there's no doubt. They also show us that not long after CO2 increases and there's an intense period of global warming, there's usually an ice age that lasts about 10,000 years and CO2 level's drop again. It seems we're either due for one or making one, but I can't figure out which.

The tundra melting, the Gulf Stream warming and slowing down, the ice flows melting 10 times faster now than they were 2 years ago, all these things are early warning signs. Once the Gulf Stream stops, it generally means major glaciation (ice almost to the tropics) in 50 years or less.

Your previous post is also interesting in this context I think. Sheep and cattle are major contributers of methane, along with us...

The ice cores are a strong message to change. Let's hope the next US election shows people have received the message.

The link between Mind and Social / Environmental-Issues.

The fast-paced, consumerist lifestyle of Industrial Society is causing exponential rise in psychological problems besides destroying the environment. All issues are interlinked. Our Minds cannot be peaceful when attention-spans are down to nanoseconds, microseconds and milliseconds. Our Minds cannot be peaceful if we destroy Nature.

Industrial Society Destroys Mind and Environment.

Subject : In a fast society slow emotions become extinct.
Subject : A thinking mind cannot feel.
Subject : Scientific/ Industrial/ Financial thinking destroys the planet.
Subject : Environment can never be saved as long as cities exist.


Emotion is what we experience during gaps in our thinking.

If there are no gaps there is no emotion.

Today people are thinking all the time and are mistaking thought (words/ language) for emotion.


When society switches-over from physical work (agriculture) to mental work (scientific/ industrial/ financial/ fast visuals/ fast words ) the speed of thinking keeps on accelerating and the gaps between thinking go on decreasing.

There comes a time when there are almost no gaps.

People become incapable of experiencing/ tolerating gaps.

Emotion ends.

Man becomes machine.



A society that speeds up mentally experiences every mental slowing-down as Depression / Anxiety.

A ( travelling )society that speeds up physically experiences every physical slowing-down as Depression / Anxiety.

A society that entertains itself daily experiences every non-entertaining moment as Depression / Anxiety.



FAST VISUALS /WORDS MAKE SLOW EMOTIONS EXTINCT.

SCIENTIFIC /INDUSTRIAL /FINANCIAL THINKING DESTROYS EMOTIONAL CIRCUITS.

A FAST (LARGE) SOCIETY CANNOT FEEL PAIN / REMORSE / EMPATHY.

A FAST (LARGE) SOCIETY WILL ALWAYS BE CRUEL TO ANIMALS/ TREES/ AIR/ WATER/ LAND AND TO ITSELF.
