Global warming has caused irreparable damage to our environment. Almost all scientists agree that IN FACT climate change is a problem. Our planet is becoming unfit for human life. Now the question is can we adapt in time? (1999)
Human induced climate change is an exponential component of an unordered system (chaos theory). That means global warming is accelerating at a rapid rate in a complex way. From 1992 through 2023, we presented evidence and suggested remedies to mitigate climate change. By 2023, the data was undeniable that human induced climate change is destroying our habitat at a rapidly increasing rate.
"For people, for other species, for the ecosystems, for the world we live in, we've entered the Age of Loss and Damage, but we're just at the start. What we are seeing already just makes you want to cry," said Dr. Christopher Trisos from the University of Cape Town. "We can't eliminate loss and damage. It is here. That said, there is a lot we can do to limit it."
The 20th-century surface temperature average for Earth was 13.9℃.
In the first weeks of July of 2023, the average temperature was 17℃.
Q: Is it possible for humans to survive at temperatures greater than 3℃?
A: Probably not long. Humans have never done it before.
September 6, 2023: "Climate breakdown has begun," the United Nations Secretary-General Antonio Guterres warned the world after the World Meteorological Organization (WMO) reported the world endure its hottest Northern Hemisphere summer in human history. "The dog days of summer are not just barking, they are biting," the UN chief said in a statement after the report's release.
"What we are observing, are not only new extremes but the persistence of these record-breaking conditions, and the impacts these have on both people and planet, are a clear consequence of the warming of the climate system," C3S's Climate Change Service Director Carlo Buontempo said.
Climate Breakdown is the most concerning development. Climate breakdown happens when feedback loops are created and tipping points are crossed. Plants will become extinct and many carbon sinks will vanish. The Earth’s temperature will continue to accelerate at an exponential rate no matter what humans do. Food, fresh water, and breathable air will cease to exist. Humans will likely follow in short order.
In October of 2023, the European Space Agency's Copernicus Climate Change Service calculated that the average temperature for September was 16.38 degrees Celsius (61.48 degrees Fahrenheit) breaking the previous record set in September 2020 by a half-degree Celsius (0.9 degrees Fahrenheit). This is the largest increase in a monthly record high ever.
"It's just mind-blowing really," said Copernicus Director Carlo Buontempo. "Never seen anything like that in any month in our records."
"This is not a fancy weather statistic. It's a death sentence for people and ecosystems. It destroys assets, infrastructure, harvest," Imperial College of London climate scientist Friederike Otto said.

The Age of Loss and Damage
Humans will experience greater loss and damage to life and quality of life from air pollution, decreasing supply of potable water, heat stress, and disease.A warmer world will present widespread challenges across many aspects of food-energy-water security and economic development. Infrastructure including roads, bridges, sewer and water plants will become unsustainable. Personal property will suffer loss and damage as homeowners and flood insurance become increasingly difficult to obtain.
Loss and damage litigation against oil companies and governments will change world economics.
Imminent Risk: Violent Rain
In October of 2023 Sidd said, "Now I am thinking the violent rain will be a bigger problem before we die... still thinking it through. In the long run, ya, sea level rise will hit big. If you look at the history, it is episodic, and in the fast bits it can go up 3 feet every twenty years for five hundred years. But, the rain intensity is increasing faster today, and drainage cannot cope, whether in the city or out, culverts and such put in over the last hundred years cannot handle. So, I am paying a lot of attention to terrain and drainage far inland from the seacoast (like Ohio.) By drainage I don't mean just human built. I mean that the natural streams and gullies and ravines have not evolved to a state that can handle the water volumes we see and the worse, larger volumes we will see. So expect huger erosion, steeper slopes to waterways, land collapses and such. Build out your drainage."The rain intensity is increasing faster today than ever known. Multiple factors figure into the physics of violent rain. The Momentum of Rain is p = mv (p = momentum, m = mass, v = velocity.) Part of the increasing momentum is transferred to the sides and upward increasing wind turbulence, as well as updrafts. Most of the momentum is transferred upon impact. You may notice the rain bouncing higher off the streets and sidewalks. As rain becomes more massive, it will have greater momentum when it hits the ground causing more damage. The momentum of rain and the turbulence of wind are part of a larger equation that includes not only the mass and velocity of precipitation but also the density. The combination of these variables results in an increased intensity of the flow dynamics. Increased updrafts will result in an increase in the frequency of hail. When violent rain becomes denser and turns into hail, it can be deadly. Ground without groundcover will be hit harder causing more damage. The groundcover will also be hit harder causing more damage. Concrete, asphalt, solar panels, roofs, and plants will sustain more damage. Hail may also impact your skull. Infants and young children are at highest risk. Several infants have been killed by hail in the past year.
Wind and water flow forces scale as the
square of velocity, so as flow speeds increase (say due to more
intense heating or heavier rain) the damage scales as the square of the velocity.
Look at drag physics and you will see that force is proportional to
density times square of velocity (v^2). So a twenty mile an hour wind exerts four times as much force as a ten mile an hour wind. And a forty mile an hour wind exerts sixteen times as much force as a ten mile an hour wind. A wind of fifty miles an hour exerts twenty five times and a wind of sixty miles an hour exerts thirty six times as much force as one of ten miles an hour.
Then you have the density term. Water is about eight hundred times denser than air, So the force exerted by a ten mile an hour flow of water is eight hundred times that of a ten mile an hour wind.
So as flow velocities go up due to climate change, force and damage scale as square of the velocities. What is not clear is how much these velocities increase with climate change. But in a sense we are seeing this already as, for example, flood and sewage systems succumb and hillsides fall down, and so on.

Long Term Risks: Tipped Tipping Points, Feedback Loops, and the Domino Effect
Tipping points are Critical Milestones that directly impact the rate of acceleration in climate change by multiplying the number and intensity of feedback loops.
Tipping points, when crossed, trigger self-sustaining feedback loops that are no longer dependent on
human activity. Similar to when a domino topples over hitting two more dominoes that in turn fall hitting more dominoes. Thus, the name The Domino Effect. It can also be visualized as The Snowball Effect. A tipping point is like a snowball rolling down a hill growing in mass and velocity (momentum). When a tipping point is crossed, it results in cumulative and reinforced global warming.
A look at five (5) of the multiple tipping points that show the proverbial snowball is already rolling. The first dominoes have fallen and will continue to knock down more tiles with each escalating step.
Crossing even a single tipping point is alarming. For instance, crossing the tipping point for 'mountain glacier loss' has immediate consequences: millions of people in Europe will be impacted by the lack of fresh water. Billions of people that live along coasts will be impacted by the saline infiltration and eventually by the submerging of their property. In September of 2022, UNESCO reported accelerated melting of glaciers in World Heritage sites, with glaciers in a third of sites set to disappear by 2050. In September of 2023, the GLAMOS glacier monitoring center found 10% of Swiss glaciers had disappeared in the last 2 years. They do not expect any Swiss glaciers will be left by 2050 no matter what actions are taken. If extreme measures are taken, they anticipate we may be able to save some polar glaciers.
This in and of itself should be alarming; however, it gets worse. Tipping points are parts of feedback loop systems. The ice-albedo feedback loop is an expression of the ability of surfaces to reflect sunlight (heat from the sun). Any loss of ice over a darker surface means the surface will absorb more heat and reflect less heat. This process makes the Earth warmer causing more loss of ice, which in turn causes more warming of the Earth. So, yes, the mountain ice tipping point is quite alarming for both its immediate impact as well as its self-sustaining growth to global warming; but wait, it gets more alarming. The increasing temperatures due to crossing a tipping point cause other tipping points to be toppled (The Domino Effect).
By the Autumn of 2023, it had become evident
the West Antarctic and Greenland ice sheets will completely melt. The process is irreversible and inevitable.
The cool water from the melting ice at the poles is being drawn toward the center of the Earth and getting warmed to record high temperatures. The warm, moist air is circulating and moving over land. These changes in climate systems will cause other areas to experience unprecedented drought.
We expect sea level rise will total about 270 feet
over the next several millennia.
It is episodic, and in the fast bits it can go up 3 feet every twenty years for five hundred years.
The melting Arctic and Antarctic have multiple feedback loops including: enhanced oceanic heating and ice-albedo, Planck feedback, lapse-rate feedback, and cloud feedback.
The tipping point for the collapse of AMOC (Atlantic Meridional Overturning Circulation) was thought to be centuries away, at the earliest. In July of 2023, the study Warning of a forthcoming collapse of the Atlantic meridional overturning circulation was published in the journal Nature Communications. "Here we provide statistical significance and data-driven estimators for the time of tipping. We estimate a collapse of the AMOC to occur around mid-century (2025-2095) under the current scenario of future emissions." The collapse is likely to cause faster sea level rise on the east coast of the US, more severe storms in Europe, and increasing drought in the Sahel in Africa. "From the study of past climate, we know changes in the AMOC have been some of the most abrupt and impactful events in the history of climate," said Prof. Stefan Rahmstorf, at the Potsdam Institute for Climate Impact Research in Germany and world leading oceanographer. During the last Ice Age, winter temperatures changed by up to 10C within three years in some places. "We are dealing with a system that in some aspects is highly non-linear, so fiddling with it is very dangerous, because you may well trigger some surprises," he said. "I wish I knew where this critical tipping point is, but that is unfortunately just what we don't know. We should avoid disrupting the AMOC at all costs. It is one more reason why we should stop global warming as soon as possible." A feedback loop created by the AMOC tipping point would cause a disruption of weather systems and circulation. The result would be the loss of naturally occurring carbon sinks. One scenario is desertification of the Amazon rainforest. In 2023, the Amazon River and the Rio Negro set record low levels.
The tipping point / feedback loop problem is very complex (chaos theory) and exponentially alarming. Yet another tipping point appears to have been triggered before 2024 -- Amazon Rainforest Dieback. The Amazon is often referred to as 'the lungs of our planet.' Not only does the Amazon suck in huge quantities of CO2 and breath out O2, but the Amazon soils also store huge amounts of CO2. The desertification of the Amazon would result in a release of the carbon as the soils disappeared.
1) part of July was spent at record temperatures +3C
Low river levels and hotter waters have killed masses of fish seen floating on river surfaces, contaminating the drinking water, Environment Minister Marina Silva said. "We have a very worrying situation. This record drought has disrupted river transport routes (dropping 30 cm / day) threatening food and water shortages, and a large fish mortality is already beginning." This was the effect of a periodic El Nino mixing with changes in weather patterns brought by global warming. "We are seeing a collision of two phenomena, one natural which is El Nino and the other a phenomenon produced by humans, which is the change in the Earth's temperature." Worsened by climate change, this combination has caused drought not seen before in the Amazon and "is incomparably stronger and could happen more frequently."
Rio Negro Climate Change Case Study
Most of the carbon discharged into the water helps the carbon to eventually sink in the ocean as a literal carbon sink. The lack of rain and drought conditions result in more vegetation dying and contribute to a feedback loop -- more plants die from less rain... and there is less rain to wash the excess carbon to the bottom of the ocean... resulting in more global warming... resulting in more dead vegetation.
A study of Dissolved Organic Carbon (DOC) in South American rivers found, "Small and steep catchments hosting organic rich forest soils and peatlands were the most sensitive and showed the highest and fastest DOC release if evaluated on a per unit area basis. Here, rain events caused a rapid exponential increase in DOC release...."
The study Effects of natural light and depth on rates of photo-oxidation of dissolved organic carbon in a major black-water river, the Rio Negro, Brazil found under natural sunlight during the dry seasons rates of complete photo-oxidation and changes in absorbance indices decayed exponentially. The deeper the water the less CO2 emissions created and the more carbon is sequestered at the bottom of the ocean.
The Amazon river was also at record lows during 2023. The drought conditions in the Amazon rain forest are unusual. We are watching the Rio Negro and Amazon Rivers as a case study for the slowing and/or collapse of the AMOC, the die-back of the Amazon, and the carbon cycle.
Conclusion
Feedback loops and tipping points are parts of an equation that
determine the rate of acceleration in climate change. Triggering these tipping points results in the CO2 stored in nature to be released without the assistance
of humans. Though we do not know how much carbon is stored in nature, it would be reasonable to assume that the temperature could be pushed from 3 degrees to 6 degrees above pre-industrial levels. Humans cannot thrive above a rise of 1.5 degrees. Much of the Earth will be uninhabitable if the temperature rises an additional 6 degrees Celsius. If humans also add 3 degrees Celsius, the temperature and humidity will approach a wet-bulb temperature that will not
sustain human life.
For the first time in human history, global warming is going to continue no matter what humans do. Even if
humans stopped their greenhouse gas emissions today, humans have invoked nature's greenhouse gas emissions.
Nevertheless, the sooner humans stop their emissions, the better.
In addition, humans must adapt their habitat to remove, reduce, and hinder nature's greenhouse gas emissions.
What Can I Do?
2) the collapse of the Amazon rainforest is likely to happen between +2 - 4C. The collapse of the Amazon is expected to occur because of changing weather patterns and circulation that result in drought.
3) Brazil set up a task force for "unprecedented drought in the Amazon"
What do you know about the Rio Negro as it relates to climate change and carbon sinks? The Rio Negro gets its name from its color. The black water is caused by highly acidic and carbon rich water. One scientist that lives on the river called it similar to Coca-cola. In 2023, the Rio Negro recorded record low levels.
The carbon sequestration from dissolved organic carbon is only one of the many carbon sinks in the Amazon. It is likely Amazon droughts will become more frequent and intense resulting in decarbonization at an exponential rate. The collapse of the AMOC will hasten the collapse of the Amazon. The collapse of the Amazon will hasten the collapse of the AMOC.
There are plenty of things you can do to help save the planet. Stop using fossil
fuels. Consume less. Here is a list of additional actions you can take.
