 It is fashionable for people to create sympathy to the unseen / unknown organisms. The poor things that can't stand up and fight for their own existence.

It makes for a brilliant narrative. It melts your hearts. And you get to play saviour of the oppressed by outraging. /1
But, for most part, such things are also false.

Amazon are the lungs of the world. Never mind that most of the world's oxygen production happens in open oceans. But these are harmless ones. Of course, we all love to maintain forests.
However, some things are sheer scare mongering.

For instance - take this: coral reefs will be permanently gone if mean / median temperatures raise by 1°C ..

But, really - how? Then you get a lecture on how CO2 will affect calcification.

Dig a bit deeper from another angle+
+ and you find that the earth was much much warmer during the age of Dinosaurs. So much so, that we had cold blooded lizards growing to sizes of buildings. Surely, there must have been tons of CO2 then!

And the ocean temps were quite high too.
How do we know corals survived it? Wasn't that a long time ago?

Here is the catch - Corals have been in existence for the last one billion years (or more).
No one asks, why would this 1° raise kill corals if the much warmer Triassic temps didn't?

Second one are news like the one quoted above. (Shark eggs are unviable **due to global warming**).

This is a false flag. Is there a correlation between these two? Maybe.
Is there a proven cause effect? It is almost impossible to do. While one can argue the reverse is also valid: that one can't disprove this isn't due to temperature, we can derive lessons from other strands of nature.

Intriguing and relevant are lessons from the fruit fly!
The fruit fly is a good system for drawing some inferences and ask the same questions of other systems. Like sharks or corals.
In 2010, Frankel et al published an excellent paper

https://t.co/8Q9ARW5iV5

Some background: information in DNA is controlled by short segments of DNA called enhancers. In 2010, Frankel et al found a particular enhancer that seemed redundant.
The function regulated by this family of enhancers was embryo development. That is the growth of the fly from its egg.

They deleted this "redundant" copy of the enhancer, and saw that it had zero impact on development. But then - when they deleted it and ++
++ grew the eggs in elevated temperatures, the eggs didn't develop into full live insects.

That is, this seemingly redundant enhancer was a contingency plan put in place by nature to deal with unforeseen events.

It is entirely coincidental that the best example to ++
++ describe contingency plans in living systems also involves survival in increased temperature.

Now we can at least use these lessons to ask questions about Sharks and corals!

If Drosophila, a relatively recent organism, can have contingency plans - won't the sharks have it?
Sharks have been around since before bony fishes. they have been around for 450 million years. They have seen the landmass become Pangaea, and then split again. And yet, we are to believe that sharks haven't witnessed / survived global temperature changes.
If sharks have it - logically they should - why won't the corals have it?

Remember - the entire argument isn't about whether or not warming occurs .. but it is about whether the scaremongering holds water.

If we have understood something about life, it is that it survives.
But then, does it mean there won't be any impact?

No. That is not the message. It is that the lower an organism is on the evolutionary scale, the lesser it will be hit.

Someone mentioned polar Bears. They will be hit. They are complex organisms with specific habitat reqs.
So, naturally - that organism which is most fastidious about its habitat, will be the most hit with climate change?

Guess the most fastidious numerous animal? Humans.

Climate change - irrespective of the cause, is seen to affect glaciers. No amount of wishing away changes it.
Humans will be the hardest hit - especially in zones where they are concentrated with depleting fresh water and forest cover (we come to rain forests again).

The complex web of life means that the over exploitation is the problem. So what is the way ahead?
Spoiler alert: short of cutting down human population by 90%, there is no solution.

All the measures (green tech) is just band aid on a open surgical wound. You can assuage your heart .. but it won't stop.

Take the example of China. ~1.25B people.
Think about it: China is a growing economy that wants to become a first world country in a hurry. It has 1.25B people.

What does it mean to be a first world country? Typically two things: food + water surplus, energy surplus.

What did China do to address these problems?
It trawled the oceans! And how?

https://t.co/2MkOv6O6CG

And they have been doing it for almost two decades now.

What the white man did to American Bison, Chinese are doing to the oceans. In a far larger scale.
As for water, we know their dam building activities. To think dams don't affect life forms is naive, so I will leave that there.

Last is Energy: China gets as much as 60% of its total energy from burning coal.

Energy is the currency of civilization.
And what we discussed is just one 1/6th of the global population. India is trying to climb the same ladder.

Everyone wants AC to protect them from the summer. Everyone wants a car. Everyone wants fresh water and food.

Nope. Global warming isn't going anywhere.
Then the argument is "don't have kids. Save the world". This is as foolish an argument as any. Having one child who would take the fight to save the world to the next generation, outweighs leaving the world to those who don't think it needs saving.

Politically incorrect.
What then is the solution? Likely, none for the next 200yr (short of a catastrophe).

For now, understand that anyone promising to do this within the next 30yrs is bullshitting.

Why? After India, it will be the turn of entire African continent to become energy and food surplus.
So, the only hope for the world is to become energy rich as soon as possible - and built technologically protected enclaves to save as many species as possible -- while keeping the population growth rate slightly negative and let it fall to sustainable levels.
Don't be anti technology. Organic sounds good. But GMO that produces twice as much food for the same resources, is much better. Don't shy away from incrementalism. Don't shy away from talking the stark truth: we will have to exploit nature to keep humans alive.
If you have to exploit the oceans to give humans food and water, you have to do it. Else, someone who is willing to do that will come to power. You won't like it, but you won't have a choice either.

Like all things humans - civilizational values are key in resolving this issue.
And with that we come to this last point. Not all civilizations are made equal. Some have values that are inherently better suited to sustainable living and existence than others.

Pick your value systems carefully.
Last but not least, and circling around to where we started: it is easy to tug at the nice part of your heart. It is difficult to reconcile the harsh realities with what we want it to be. Don't give into rhetoric of revolutionary changes and fast solutions. They are ruinous.
End of rant: don't take it at face value just because a scientist says so. Measure everything up against reality. You will see that most scientists are just cocooned IYIs. It takes wisdom to solve problems. // Fin.

1) OBSERVATION: The frequencies are changing. I would have to assess stats on the electromagnetic field to see its fluctuations. All I know is, I am highly sensitive to energy/frequencies, and they are changing, because…

2) 2 Weeks ago, my dog was effected by it as well. He is hearing things that aren’t technically audible. I can tell by his body language and sounds. One week ago I began feeling a pressure in my head and ears. It wasn’t painful at all, but it was intense for a bit.

3) It reminded me of taking off in an airplane a bit. I felt like I was in a vacuum. It went on and off for a couple of days. I’ve picked up on frequencies and high pitched sounds (not audible to most) for 30 years, and today my right ear began to ring for longer than usual.

4) This is nothing unusual for me, with exception of the duration. This happens often with me. No, it’s not tinnitus. Only this time, when I spoke, there was reverb creating a high pitch in my ear from my voice. This lasted for about 30 minutes. It did not hurt, just annoying.

5) So yes, the frequencies are changing. What this means exactly, I am unsure of at the moment. Some will say electromagnetic fields, others will say ascension, and some will say pole shift. I honestly can’t say at this very moment.

Get a cup of coffee.

In this thread, I'll help you understand the basics of Binomial Thinking.

The future is always uncertain. There are many different ways it can unfold -- some more likely than others. Binomial thinking helps us embrace this view.


2/

The S&P 500 index is at ~3768 today.

Suppose we want to predict where it will be 10 years from now.

Historically, we know that this index has returned ~10% per year.

If we simply extrapolate this, we get an estimate of ~9773 for the index 10 years from now:


3/

What we just did is called a "point estimate" -- a prediction about the future that's a single number (9773).

But of course, we know the future is uncertain. It's impossible to predict it so precisely.

So, there's a sense of *false precision* in point estimates like this.

4/

To emphasize the uncertainty inherent in such predictions, a better approach is to predict a *range* of values rather than a single number.

For example, we may say the index will return somewhere in the *range* of 8% to 12% (instead of a fixed 10%) per year.

5/

10 years from now, this implies an index value in the *range* [8135, 11703]:

I think we have to expand our thinking about the toroidal sphere even more. When looking at maps, I noticed the da Vinci map, from 1514, which uses the Reuleaux Triangle. This triangle is formed from 3 intersecting circles, and is in the center of a trefoil.


The trefoil is the focal point in many gothic structures, repeatedly and prominently shown. It is represented in many ways. ‘Going down the rabbit hole’ now makes sense, if you understand the center point of the ears is the center of the torus, with the rabbit trefoil.


The trefoil can be found within the toroidal field. Here is a fun site, where you can manipulate it yourself. https://t.co/FCMcybuuFC


The wiki page makes it seem like there isn’t much of importance with the Reuleaux Triangle, besides being used for coinage, or some stupid bike. But the Wankel engine is an interesting engine, using this geometric design https://t.co/ayPOgkAqGN

Maker movement is doing to startups what startups did to corporations.

Here is why 👇

Startups fixed the problem of innovation, that corporations lack.

In big, slow corporations, innovation is a RISK and distraction from the core $$$ profitable business.

Agile startups could launch, iterate fast and eventually stumble upon new growing market opportunities.

However,

When a startup reaches product-market-fit, it has to 🚀 "grow at all costs" and reach market dominance before some giant corporation can replicate their new product and distribute it to their existing giant customer base.

Startup's "growth at all costs" often means growth at the expense of charging customers $$$ money.

Hence, to be sustainable, startups have to constantly chase investor money.

Startup teams spend more time finding and pleasing investors, than finding and pleasing customers.

95% of startups die because they run out of (investor) money + no business model + crazy investor expectations.

Same way corporations die, when unable to adjust to new technology and market shifts.

Some thoughts on episode 53 of #Hercai

Love,that is not real,has no passion. Its fire turns into embers, it doesn’t not smell. The day, the night, the moon&year burn without sun, light, comfort&sleep.

1
PRAISE
The praise in this episode goes foremost to Ebru because she portrayed Reyyan so realistically like a woman who truly lost her unborn child. I was in awe and pain watching her along the episode, all her breakdowns and tears were so real.
#Hercai

2
Of course also Akın took his part and did his part masterfully, but he rightfully was the one who stood aside in this specific episode that needed to be about Reyyan’s pain and thus concentrated on Ebru.
#Hercai

3
And last but not least, if I say thank you to something that B gave us this year, then it’s to have Ali as our director. Also in this episode we saw the artistic eye behind every shot and I loved it.
#Hercai

OVERALL COMMENT
I don’t know who wrote ep. 52 but ep. 53 was going strong once more on symbols: roses, stones, fire and trees were incorporated and especially the ReyMir dialogues were written very well. I truly loved every ReyMir scene.
So let's get into it.

1. “Who Are Ireland’s Members Of The World Economic Forum Implementing The Great Reset In 2021 ? 🧵1/28

🕵️🔎 Politicians, Musicians, Clergy, Bankers, Journalists, Human Rights, Artificial Intelligence, Sustainability, Corporations & Agriculture


2. In previous threads I have looked at 🇮🇪 key players in the Trilateral Commission as well as 🇮🇪 people who have attended the Bilderberger meetings. I also looked at the 🇮🇪 in the Young Global Leaders which is a site run by the WEF. You will see a lot of crossover between them.

3. The purpose of this thread is to compile all the Irish members into one thread for ease of access and reading rather than having to dive through the WEF site. This is by no means definitive and I will be adding more over time when they pop out of the woodwork.

4. Ireland’s WEF members are drawn from all walks of life but can be split into 2 separate areas. The WEF calls the first category “people” and the 2nd one “agenda contributors”. In total Ireland has a minimum of 61 members. Some of the names will be familiar and others will not

5. In this thread I’m just going to concentrate on the 21 people (there are probably a lot more). There are also 40 “agenda contributors” which I will cover in a separate thread. The agenda contributors are those who write articles or do research for the WEF site.

SRI CHAMPAKADHAMA SWAMY, BANNERGHATTA HILL, BENGALURU (KAR)
#bharatmandir

The shrine is dedicated to Sri Vishnu along with Devi Lakshmi and Bhoodevi.
It is built in an area full of Champaka trees.
As champaka flowers are offered to Sri Vishnu here, it is called Champakadhama.


It is believed that King Janmejaya had sarpa-dosha. To get rid of it, he took bath in the nearby pond. He emerged with a golden body and sarpa-dosha was also removed. The pond is called Swarnamukhi and believed to have curative powers.
Sri Vishnu murti was consecrated by him.


It is also believed that this forest area was the Dandakaranya where Sri Ram stayed in exile.
Some believe that the original shrine was built by Pandavas.
The pushkarni/pond is emptied once a year so that the rock at the bottom (which has image of Anjaneya) may be worshipped.

Hinduism is a minority religion in Punjab.

During the Khalistan movement, the minority Hindus and Jains were subjected to several attacks. Hindu and Jain temples were frequently vandalized and desecrated. This thread documents a few instances.

Thread

Durgiana Mandir is one of the oldest temples of Amritsar. According to the regional Hindu tradition, the temple was built on the spot where Lava and Kusha bound Hanuman. The temple annually attracts millions of Hindus from all over the country.


Amristsar has a very ancient Hindu history.

According to the regional Hindu tradition recorded in the "Survey of Amritsar", Amritsar got its name from Amrit immersed by Lava and Kusha in a pond.


Durgiana Mandir was rebuilt in 1921.

It was used to house the Murtis of Vishnu and Durga which were thrown out from the Parikrama of Harmandir Sahib in 1905.

Because of its presence in Amritsar, it became a frequent target of radicals during the Khalistan movement.


In 1982, in what was a completely unprovoked attack, the Dal Khalsa "activists" threw a severed cow head inside Durgiana temple.
