8/15 (Tue.) What will happen after the ocean circulation shut down.(Host: Miller)

文章 miller »

This is Miller, the host of the coming meeting on 8/15.
Scientists are warning that a crucial tipping point could be reached in 2025
- that would see the start of the collapse of the Atlantic Gulf Stream - if global emissions were not reduced.
The Atlantic Meridional Overturning Circulation, known as AMOC, drives the Atlantic's currents
- by pushing warm water from the Gulf of Mexico northwards, towards the Arctic, where it cools and sinks.
It last collapsed during the previous ice age around 12,000 years ago - and could have catastrophic impacts on humanity.
Sea levels would rise around the East Coast of North America - and storms would worsen in Europe.
While rains in Asia, Africa, and South America would be disrupted - causing issues for food production for billions of people.

What is happening in the Atlantic Ocean to the AMOC?

Session 1:
Q1. Did you ever find some weird circumstances that are climate-change related in your life? Why do you think it is related?
Q2. The last time the earth was at 5C hotter then 95% of species went extinct. We are on track for around 4C by 2100, other scientists state between 7 and 9C by 2100.
Do you believe we are going on the same trajectory? Why or Why not?
Q3. As your imagination, what can happen on the earth if The Atlantic Meridional Overturning Circulation(AMOC) is shut down?
Q4. Most of us can be aware of the heat wave happening all over the world this year is worse than any past year. If the temperature next year gets higher furtherly, what is your strategy to live your life?


Session 2:
Q5. The tipping point may be coming before this century end. Do you agree it's too late to think that we can correct our trajectory?
Q6. What we need is the recognition that our economy and our way of life need to be changed drastically to reduce CO2 emissions significantly.
The assumption that technological innovations can save us from catastrophe is unrealistic. Do you agree with that? Why and Why not?
Q7. To reach the 1st billion, it took time from the beginning of humanity till 1900. So it took nearly 500,000 years or more for the human population to get the 1st billion.
Since 1900, we have added another 6 billion and counting. So we added another 6 billion in just 123 years. Do you think the human population is the cause of climate change?
Q8. If you had seen the film "The Day After Tomorrow", what would you do if it occurs in real life?

"reality doesn't exist until observed", the notable observer effect occurs in quantum mechanics. I know it's philosophical but, that's also what quantum theory actually tells us about life I would say. When it comes to environmental problems, be that as it may, I believe that reality doesn't exist until observed. Right, I don't even know what I'm talking about. :lol:
i might be a cynic and, a sceptic as well but, i'm definitely not a bad person!!

“Reality doesn't exist until observed.” It sounds like “Reality is seen as a form of projection” in Buddhism. I appreciate that it often offers a philosophical perspective to alleviate our guilt and burden for things out of our control.

Mostly, we trust science, with a “show me numbers” mindset. Scientific statistics illustrate that AMOC is approaching the tipping point, and climate changes continue weakening the AMOC. Population growth worsens climate change, but not proportionally. The rich create more carbon pollution and the poor bear more the brunt of the impacts of climate change. A survey said the richest 1% generates 25% of carbon emissions.

Solution? Remember the Japanese novel, “Life Termination at 70, Bill Passed”? To solve its population burden, anyone reaching 70 years old must be terminated. If we can “wipe out” the top 1% of the richest people, we can immediately reduce 25% of carbon emissions! “Wipeout” sounds cruel, maybe just getting them into “concentration camp” would be enough. :)

Let’s be serious. The pace at which we have been trying to restrain the progression of global warming seems too sluggish. Sometimes I feel doomed, then I retreat into philosophical pondering: “Who gets to determine that the Earth should exist eternally?”
