We Can’t Go Back Once Climate Change Hits A Tipping Point, Warns Climate Reality Activist Bill DeVincenzi

Our Climate is Changing. Why Aren’t We?

What happens when ice caps melt, forests die, the permafrost thaws and microbes multiply?

Climate Reality Activists Bill DeVincenzi and Erin Zimmerman join DesiCollective to clear up some misconceptions  about the pace of climate change. Scientists warn that we are in 6th extinction and that some of these changes are irreversible. Humans only have a ten year window to reverse the chain reaction of ‘feedback loops’ that are escalating the climate change crisis. The world is at a tipping point which can put us over the top to runaway climate change.

 

A Short Primer on Feedback Loops with Bill DeVincenzi & Erin Zimmerman

Climate Reality Leader Bill DeVincenzi

What’s A Feedback Loop?

A feedback loop is defined as a certain set of circumstances that can become self-perpetuating. They are present in everything from machines, and economics, to biological processes. They can be both positive and negative; however, in the case of climate change the consequences would be bad. Very bad.

Why Feedback Loops are Bad

Feedback loops are important to consider when trying to halt the climate crisis. And while entire books can, and have, been written about them, here’s a short primer on why climate action is essential now, and not at some point in the future.

When Earth Loses Its Best Reflector, that’s The Albedo Effect

You wouldn’t think the earth’s reflectively matters but it does. The Albedo effect, or loss of earth’s reflectivity is probably one of the most dangerous, and little known feedback loops. While much of the sunlight that hits the Earth is absorbed, some is reflected into space. You’ve probably experienced the Albedo effect if you have gone skiing or visited the high mountains in the winter. Snow and ice reflect around 85% of the sunlight that hits it and keeps the planet from getting too warm. But the volume of ice around the world has decreased by 75% in the last 40 years. According to scientists, we could lose Arctic sea ice completely by the end of this century. The ocean absorbs about 90% of the sunlight that hits it. So, we are replacing the best reflector, sea ice, with the worst absorber, open ocean. If you add in the loss of snow and ice on land as well, this adds up to approximately 40% loss of reflectivity. More heat absorbed means a warmer planet and results in even more ice melt and the cycle repeats itself.

Permafrost Melt Releases Methane – It’s Wrapping Earth in a Warm, Toxic Blanket

Thousands of years ago, an icy cover in the North froze billions of tons of biological material to create Permafrost.  When permafrost melts, the biological materials thaw and then decompose, releasing the greenhouse gasses (GHGs) carbon dioxide (CO2) and Methane. GHG’s are like a blanket that covers the Earth, keeping it warm. As the blanket gets thicker (more GHG’s), the planet gets warmer. Today, permafrost keeps twice as much CO2 in the ground as there is CO2 in the atmosphere right now. If this CO2 is released, the consequences could be devastating. It’s vicious cycle. As global temperatures rise, the permafrost thaws, which increases greenhouse gasses and more warming. The cycle then repeats itself. The carbon dioxide is bad enough, but the Methane is 30 times more potent than CO2 in terms of trapping heat in the atmosphere.

The Jet Stream’s Deadly Loop De Loop

The Jet Stream ironically, is an actual loop of air current. It circles high above the earth around the Northern hemisphere between the colder north and the warmer south. The temperature differential between the two keeps the jet stream in place; however, the temperature in the North is increasing 2 to 3 times as fast as the temperature in the South. This is pushing the jet stream South; the further South it wanders, the more it picks heat from the South to carry North. This reinforces the cycle and causes wild and unpredictable changes in weather, from extreme cold spells in the South (ice storms inTexas!) to hotter days in the Arctic (or 100.4F in Siberia!). Dry areas become drier, and wet places get wetter.

Stand Up to The Folly of Fossil Fuels

As you have probably noticed, all the feedback loops start with fossil fuel emissions. If we reduce fossil fuel emissions, stop deforestation, and re-green the Earth, we can prevent or start to reverse these feedback loops.

Advocate for Climate Action or Elect Leaders Who Will

The single most important thing we can do is elect leaders who will move us in the right direction. We must vote in political leadership that will take on this problem and collaborate with other countries around the world. It is up to us to continue to put pressure on our local legislators to support the administration in the effort.

Regardless, the planet will continue to exist just fine, albeit a lot warmer, like in the time of the dinosaurs. We humans may not exist, nor would many of the species that now exist with us. So, we can sit back and let global warming wipe us out. Or we can act now to save ourselves and our fellow species. We have total control over this.

Let’s make it happen!

Are We Going to Be Normal After This Pandemic?

The answer is NO if “normal” means “status quo ante” or going back to what we were before. The answer is neither disappointing nor a surprise.  It is absurd to expect something to stay standstill in an endlessly rotating planet called Earth which is somersaulting in an immeasurably vast universe. Our impatience, however, in waiting for the dreadful pandemic to end is indisputably natural. Sure enough, It will end because nothing lasts forever.  

So what will post-pandemic pictures unfold to our weary eyes?

We have to watch what follows with cautious optimism. Jumping off the hell is not synonymous with plunging in heaven. The spectrum of the post-pandemic period will be interspersed with new challenges testing our prophetic prudence. Have we mastered our learned lessons or will our fickle memory sequester it in oblivion? If we are intelligent enough, it will prepare us for the future. For the sake of brevity and expediency, let us settle our hopes and fears in two classes.

WHAT WE HOPE FOR:

We hope to have surmised that we are truly mortals who have learned that death does not always visit us in small and scattered incidents. It may as well raid us in a sweeping, devastating way and compel us to feel like helpless prey. As we dreadfully watched the steep rise in brutal mortality caused by the pandemic, science also told us that such catastrophes are not unprecedented.

We have been frequented by episodes of smallpox, polio, plague, cholera, Hong Kong and Spanish flu, and such disasters of diseases propounded by microbes. We feel like running deers chased by a terrifying tiger close behind. The pandemic we are facing is neither the first one nor the last one. A second pandemic could well be preparing itself, waiting for its opportune time. They may be unpredictable but chronologically sequenced with the passage of time.

We hopefully are better prepared each time, cautiously cognizant for the world. We have to communicate faster than the velocity of the worms and combat by a joint endeavor. This is the only way to curtail our mortality imminent upon a visit by unanticipated invaders. Pointing accusatory fingers at who started this microbial massacre will only amputate our aiding arms. United we stand, Divided we fall.

“Let us hang in together, or indeed each one of us will hang separately,” as most prophetically pronounced by Benjamin Franklin.

A bacterial war will be won only by sound teamwork unifying the whole world as a single team. By not learning this lesson this time, we made a serious mistake of creating Divided Countries of the World and paid an exorbitant price for it. History has a pattern of repeating itself unless we are vigilantly watching with a discerning eye.

What we hope not:

We hope not that this pernicious pandemic leaves any sequelae behind. Sequela is a medical term used for complications that emerge long after the disease disappears. This infection is new to us and therefore, we are not completely knowledgeable about the course it may run. We will have to combat all complications as they come. 

Not only the physical but also the psychological damage that the pandemic can leave behind may need to be faced factually. Our particular concern should be centered around our children who have painfully grown through a period of sustained trauma and deprivations.

I met a young man who passed his childhood in a war zone. Years later, he wakes up screaming at night when hearing an ambulance pass by. Children, in general, may be equipped with greater immunity against the disease but they are also more prone to retain a sustained memory of a mental trauma that they were exposed to. No math can predict the extent of the aftermath. It is essential to remember this aspect because children of today will be the deciding fate of tomorrow.

I am also concerned that too many stream sessions and loss of interpersonal interactions may lead us to subordinate the value of human touch and direct encounters. To deal with peoples’ images rather than people themselves can push us downstream fostering a phobia for live human interactions. Our emotional and physical closeness to each other is the very bulwark on which we sustain. Let us not be unmindful that we need each other to survive and thrive.

“Hell is a place where nothing connects with nothing, “ said T.S. Elliot.

The social, economic, and emotional impact of this catastrophe should not be underestimated either. Depression, suicidal tendencies, self-effacing and destructive patterns of behavior, and horrors of hooliganism may surface much to our dismay.

Finally, we hope this tragedy does not drive us away from God. God may not protect our Temples and Churches but the secret of our love and happiness lies in God hidden in our hearts. We keep on hoping because Hope is nothing but the constancy of faith. Most faiths have accepted and established a parent-child relationship with God. The more we are disappointed, the more we turn to Him until we are hale and healed. The course of our actions will let us see who we are and who we are not. Our deepest compassion for the bereaved families should never fade.

Peace! Peace!! Peace!

Mercy, Oh Microbes!

Tigers killed the prehistoric animals, man killed the tigers, and now microbes kill the man. This sequence has been a part of our planet. Our mortal enemy is historically shrinking in size but the destruction caused by IT is getting progressively more devastating because of our lifestyle. A sweeping annihilation of human beings was neither unprecedented nor entirely unexpected.

I remember the words of our Previous Dean at Emory Medical School, who joined us from the National Institute of Health some years ago, that our most threatening enemy is going to be microbes because they have been on this planet far earlier than us and we can never compete with their rate of reproduction.

The only advantage of their vicious visit this time is the lessons they are leaving behind. I do not want to enter the details of the devitalizing vital statistics of this pandemic. Everyone knows them beyond our choice. They will be talked and written about for decades to come.

Some Lessons To Be Learnt: The tragic toll of life that the pandemic has taken will not go entirely in vain if we draw some harsh but needful lessons therefrom.

Lesson 1 – Microbial World

We are surrounded by and inhabited by a microbial world. We have to recognize the good ones from the bad ones. Giving them names such as “evil”, “monsters”, etc. makes no difference to them. They are totally blind to gender, nationality, race, age, and any such outer epithets. We saw how this pandemic eclipsed many royal members, politicians, and physicians. They have no respect for Churches or other religious places either. Many churches were their starting places. They besiege and kill indiscriminately. To keep such Bacteria at bay with the help of scientists is our only available recourse.

Lesson 2 – Indian History and Mythology

I find our Indian History and Mythology to be very instructive in this regard because we have survived many diverse disasters and catastrophes. When we find our disassociation from society so unbearable, remember that Lord Buddha, Shankaracharya, Lord Swaminarayana, Shree Rama, Pandavas have had all their share in living a secluded life. If we are talking about deaths of human beings en masse, we have witnessed many grim tragedies of smallpox, cholera, plague that frequented our country. AIDS still lingers in our memory.

If we are talking about the sudden loss of wealth, India has seen it perhaps more than any other country. I specifically think of Rana Pratap who lost everything he had and was in an exile when his wealthy businessman Bhamasha offered all his wealth and rejuvenated his spirits. I mention this particular episode to remind us that we should follow such an example to support the rebuilding of our adopted country. I believe this is a splendid opportunity for us to pay back our dues to this country by helping restore our sagging economy.

Lesson 3 – Social Distancing

I stand corrected if I am wrong, but we needed to reaffirm our familial cohesiveness. Let us evaluate how we handled our continued togetherness while in seclusion. How cohesive, supportive, and mutually fulfilling were we as a family. 

Let us create a scoreboard of self-assessment. Did the familiarity breed conflict or care? I was so happy to see children playing and couples freely walking on the street…People talked to each other while walking. I rarely saw this before. Maybe we need to restructure our life to promote togetherness.

Lesson 4 – PTSD

 Watch out for PTSD Post Traumatic  Stress Disorder. During and after this excruciating experience, our deeply felt exhaustion is bound to come on the surface.

Many of us would be compelled to recognize the loss of lives and jobs that we sustained. Wounds often bleed later after the trauma is inflicted. Depression, suicidal thoughts, addictive tendencies, a lingering fear may push us to a state of psychosis. We may need to nurse each other with kindness and compassion to promote our combined healing. No social distancing at that time!

Lesson 5 – Nature

Let us also have a critical look at ourselves. There is a precise and piquant Indian saying that when one points one finger at others, three fingers are automatically pointing at him. We have violated the fundamental Laws of Nature over the last several years. From the time of Rigveda on, we have stressed the five elements of Nature, which deserve to be respected as our basic constituents – water, wind, fire, earth, and sky. These should be maintained in harmony to retain our planetary homeostasis. We have thoughtlessly violated the respectful restraint that we should have exercised over them. This is not a superstition but an obvious proof of our violation of the Laws of Nature. There is a rising Global outcry to revert our course and trace our steps back from this grievous misdemeanor. We are OFFLINE now but need to be ONLINE to secure our future. Recognize our faults and repair them. 

Our slumber has been long enough. Let the dawn break.
