Historically in the United States, atmospheric rivers (AR) have been associated with the West Coast. Now, AR activity is getting more attention on the East Coast.
Atmospheric rivers have been putting serious rainfall melt on Greenland for the last decade, too.
Darker snow surfaces absorb more sunlight and melt quicker. This effect is visible in Greenland. Box et al.,”Greenland ice sheet albedo feedback: thermodynamics and atmospheric drivers,” The Cryosphere, v6, pp821 et seq., doi:10.5194/tc-6-821-2012 state: ” Thus, intraseasonal summer albedo variability exceeds 0.50 over parts of the ice sheet where a snow layer ablates by mid-summer, exposing an impurity-rich ice surface …” Prof. Box is now investigating soot from North American wildfires as a factor in the darkening of Greenland.

“Furthermore, our investigation of the short- and long-term relationships between moisture transport vents and modeled GrIS surface properties proves that this correspondence between the years of enhanced AR activity and anomalous GrIS mass loss is not a coincidence. Strong AR impacts cause increased melt in all areas of the GrIS and decreased SMB in the ablation zone during summer, and warm seasons with above-average GrIS melt extent are characterized by anomalously strong moisture transport by ARs over Greenland. ARs typically result in SMB gains in the GrIS ablation zone during nonsummer seasons and in the accumulation zone during all seasons. However, the intense summer SMB losses in the ablation zone during years of enhanced moisture transport outweigh the positive AR contributions to SMB in other regions and seasons. The scaling of melt versus snowfall in Figures 9 and 11 shows that the magnitude of mass loss from summer melt in the ablation zone has a much greater upper limit than mass gain from snowfall.”
In this paper see especially Fig. 9.
Then in 2018, Neff publishes again: more on atmospheric rivers causing the full surface melt in greenland in 2012.

“Rainfall at the Greenland ice sheet Summit 14 August 2021, was delivered by an atmospheric river (AR). Extreme surface ablation expanded the all-Greenland bare ice area to near-record-high with snowline climbing up to 788 ± 90 m. Ice sheet wet snow extent reached 46%, a record high for the 15–31 August AMSR data since 2003. Heat-driven firn deflation averaged 0.14 ± 0.05 m at four accumulation area automatic weather stations (AWSs). Energy budget calculations from AWS data indicate that surface heating from rainfall is much smaller than from either the sensible, latent, net-longwave or solar energy fluxes. ”
“Rainfall heat transfer contributed just 2% to the calculated melting at a 2,200 m elevation western ice sheet site (CP1 a.k.a. Crawford Point). Condensation or sensible heat transfer from the warm air mass was a far more powerful heat source. The observed amount of melting delivered by the AR could have happened without rain- fall. Yet, the impacts of rain and meltwater refreeze are considerable provided that percolation delivers the melt below where the heat can be radiated away and that refreeze-at-depth occurs. We found no evidence for the latter condition because the rainfall amount was not extreme and the surface was already melting hours before the rain- fall. Understanding any changes to the frequency and intensity of ARs appears to be a more important research target than the heat content of the liquid precipitation ARs may or may not produce Further, while rainfall that does not percolate and refreeze may not have strong surface thermodynamic impacts, rainfall contribution to the hydraulics of Greenland ice (Doyle et al., 2015) may be more consequential to ablation through ice sheet flow acceleration.”
open access, read all about it. The Watson river discharge described in the paper drains the saddle between north and south domes and is an area that i watch closely for signs of collapse. I suppose this is one.

As the Earth warms, the air will hold more moisture. More moisture-laden air moves over land and creates atmospheric rivers (Pineapple Express). The Journal EOS in the article Atmospheric Rivers Spur High-Tide Floods on U.S. West Coast said, “Atmospheric rivers are narrow bands of moisture that travel across the lower troposphere, generally at the leading edges of massive low-pressure systems. At their peak, they can carry as much water through the sky as the Amazon River does on land. They unleash intense winds and heavy rain as they surge across the Pacific Ocean, eventually making landfall on the U.S. West Coast, contributing to many high-tide flooding events.”
The atmospheric rivers also bring heavy rainfall inland causing extreme flooding. In October of 2021 NOAA said, “a convergence of storms brought more than half a foot of rain to parts of the Bay area in addition to strong winds, flash floods, and mud/landslides. They also bring the potential for heavy snow to higher elevations in the Sierra Nevada mountain range.” (Atmospheric River Hits the West Coast)
In December 2022 and January 2023, California experienced nine back-to-back atmospheric rivers; the longest stretch of continuous atmospheric river conditions on record. NOAA went on to report, “Several atmospheric rivers struck in March 2023, bringing heavy rain and snowfall to much of the West. According to the California Department of Water Resources, the statewide snowpack was among the deepest ever recorded for the end of March — 237% of normal.”
In October of 2023, a tropical storm turned into category 5 Hurricane Otis in a record 12-hour intensification. Hurricane expert Kerry Emanual said Otis was supercharged by global warming. Historically, hurricanes’ intensification was driven by ocean surface temperatures. Otis was additionally supercharged by increasing temperatures deeper in the ocean. Hurricane Otis became the strongest on record to hit Mexico’s Pacific coast. NOAA reported, “When Otis first hit, mudslides outside the city in mountainous terrain prevented crews from traveling to the city to provide aid, and according to the Associated Press, the 10,000 troops that were deployed to the area lacked the tools needed to clear mud and downed trees off roads.”

As the Earth warms, the air will hold more moisture (water vapor). When more moisture-laden air moves over land it can create atmospheric rivers. In the Northwestern USA, the atmospheric rivers are commonly called the Pineapple Express. The Journal EOS in the article Atmospheric Rivers Spur High-Tide Floods on U.S. West Coast said, “Atmospheric rivers are narrow bands of moisture that travel across the lower troposphere, generally at the leading edges of massive low-pressure systems. At their peak, they can carry as much water through the sky as the Amazon River does on land. They unleash intense winds and heavy rain as they surge across the Pacific Ocean, eventually making landfall on the U.S. West Coast, contributing to many high-tide flooding events.”
Historically in the United States, atmospheric rivers (AR) have been associated with the West Coast. Now, AR activity is getting more attention on the East Coast. “Actually their frequency is not really increasing. Meteorologists have used the term for decades. It has simply become popular by the media. Just like polar vortex,” said Jeff Boyne National Weather Service meteorologist and climatologist. Indeed, “atmospheric rivers are more frequent on the East Coast than they are on the West Coast,” said Jason Cordeira, associate professor of meteorology at Plymouth State University. “They’re just not as impactful and don’t usually produce as much rainfall.”
What is changing is the research into the types and increasing intensity of East Coast AR events. “Between 1958 and 2012, the Northeast saw more than a 70% increase in the amount of rainfall measured during heavy precipitation events, more than in any other region in the United States. Projections indicate continuing increases in precipitation, especially in winter and spring and in northern parts of the region,” as reported in The US Fourth National Climate Assessment.
Most types of East Coast ARs are increasing in intensity likely due to climate change. The study Identifying Eastern US Atmospheric River Types and Evaluating Historical Trends reports, “The impact of increasing moisture transport could be significant across the northeast corridor from Washington D.C. to Coastal Maine, as it increases the risk of extreme precipitation from landfalling ARs. The results indicate most ARs in the study domain are forced by extratropical cyclones, with lee side low pressure systems and coastal lows along the Atlantic Coast (e.g. nor’easters) responsible for producing the strongest ARs.”
How Fast Are Atmospheric Rivers Gaining Intensity?
Some areas of the world are now warming so fast, it is becoming more difficult to measure the change from “normal” or average. Jeff Boyne of the NWS said, “There are climate normals that are updated every 10 to 15 years, because the planet is warming so fast. The ENSO (El Nino-Southern Oscillation) regions are warming so fast that those normals are being updated every 5 years.” Overall, how fast is climate change accelerating? Rapidly. “It’s so far outside anything we’ve seen, it’s almost mind-blowing,” says Walter Meier, who monitors sea-ice with the National Snow and Ice Data Center. “September was, in my professional opinion as a climate scientist, absolutely gobsmackingly bananas,” said Zeke Hausfather, at the Berkeley Earth climate data project.”

The atmosphere is acting like a blanket… and the earth (land and sea) is acting like a battery. 91% of the energy (as heat) is trapped/stored in the oceans.
Feedback Loops Example
The Albedo feedback loop between the earth and the CO2 in the atmosphere accelerates global warming at an exponential rate. Albedo is the fraction of incoming solar radiation that gets reflected back into space. Carbon plays a double whammy role in feedback loops.
Brown carbon on ice, snow, or permafrost absorbs more heat and releases more carbon and methane into the atmosphere… resulting in more warming… leading to more carbon being released from the earth, etc.
Brown carbon is light-absorbing organic carbon with a very low Albedo. “This class of organic carbon, known for its light brownish color, absorbs strongly in the ultraviolet wavelengths and less significantly going into the visible,” reports the Argonne National Laboratory.
There are several feedback loops between brown carbon, lightning, wildfires, and arctic warming. Brown carbon from wildfires warms the arctic. The warmer arctic absorbs more heat causing more wildfires. In turn, more wildfires cause more brown carbon resulting in a warmer arctic. The cycle keeps reinforcing itself as it repeats.
Studies have found lightning and forest fires are creating a feedback loop. Global warming causes more extreme weather events and conditions for lightning. More lightning sparks a vicious cycle, as trees and soil set ablaze release warming CO2 creating more storms and more lightning. The study Forests at Risk Due to Lightning Fires found a sensitivity of extratropical intact forests to potential increases in lightning fires, which would have far-reaching consequences for terrestrial carbon storage and biodiversity.
More wildfires create more CO2 and more brown carbon that result in more global warming that results in more lightning strikes creating more wildfires resulting in more global warming thawing more permafrost allowing more emissions of CO2 and methane resulting in more warming, creating many more feedback loops.
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.

Global warming is causing warmer and shorter winters. Not only are White Christmases less frequent, so are icebergs, sea ice, and glaciers. An analysis and maps from NOAA found snowfall is declining globally as temperatures warm due to anthropological climate change.
As the atmosphere’s heat and humidity increase, precipitation is more likely to fall as violent rain or hail than snow. “Eventually the laws of thermodynamics mean that as you keep warming you’re just going to transition more and more of that snow over to rain. You can get away with things for a little bit, and it can hide some trends, but overall the laws of thermodynamics will win out,” said Brian Brettschneider, a climate scientist with the National Weather Service in Alaska.
Justin Mankin, a climate scientist and associate professor of geography at Dartmouth College, said with rising temperatures snowfall will not decline linearly (at a 1-to-1 rate.) Rather, there is a tipping point. Once a certain temperature threshold is reached, “we should expect the losses to accelerate. It means we can expect a lot of the places that haven’t exhibited massive snowfall declines to maybe start to exhibit them with just a little bit more warming.”
Albedo is the reflective nature of snow and measures how much light is reflected without being absorbed when hitting an object (e.g. the fraction of incoming solar radiation that gets reflected back into space). Snow has a very high albedo that reflects most of the light and absorbs very little heat. The snow-albedo feedback loop occurs when the atmosphere gets warmer due to human induced climate change resulting in less snowfall. The less snow reflecting heat back into space, the warmer the earth becomes. The warmer the earth, the less snowfall. The less snowfall, the warmer the earth.
Feedback loops and tipping points are parts of an equation that determine the rate of acceleration in climate change.

Sidd said, “Do you remember back in the early 2000’s when we thought we wouldn’t live to see the extreme changes due to global warming?”
Daniel replied, “I think 2023 is the most significant year so far. We saw confirmation of tipping points being crossed for Mountain Glacier Loss, Greenland Ice Sheet Collapse, Antarctic Ice Sheet Collapse, and potentially the Collapse of AMOC.”
Sidd continued, “We already knew that. It was Canada catching on fire that I could not believe. I never
thought I’d live to see the day.”
Daniel asked, “Do you think the permafrost and peatlands will have zombie fires and cause the permafrost tipping point?”
Sidd responded, “Yes. They are gone, too. We already know from the permafrost peatland fires in Siberia.”
NASA reported: Wildland fire experts have described Canada’s 2023 fire season as record-breaking and shocking. Over the course of a fire season that started early and ended late, blazes have burned an estimated 18.4 million hectares. Hundreds of fires exceeded 10,000 hectares (39 square miles), large enough to be considered “megafires.” These megafires were also unusually widespread this season, charring forests from British Columbia and Alberta in the west to Quebec and the Atlantic provinces in the east to the Northwest Territories and the Yukon in the north.
Forest fires cause a carbon feedback loop. The carbon emissions of Canada’s fires outweighed the combined emissions from its oil and gas, transport and agriculture sectors. The fires also cause the melting of the permafrost and zombie fires to burn in the permafrost. The permafrost collapse is a self-sustaining feedback loop/tipping point. As the permafrost melts, the peatlands emit CO2 and methane. The increase in CO2 and methane results in more warming that results in more peatland emissions.
The study Wildfire as a major driver of recent permafrost thaw in boreal peatlands published in the Journal Nature Communications found wildfires have caused a quarter of permafrost thaw (2,000 square kilometres) in Western Canada’s boreal peatlands over the past 30 years. “Historically, permafrost in this area underwent a natural cycle of thawing and reforming, but given current climate conditions and projections for the future, this fire-induced thaw appears to be irreversible,” said Carolyn Gibson, who conducted the research.

Dr. Sidd Mukherjee said, “Latest frightening news” — State of the Cryosphere Report-2023.
This has been a year of climate disasters and ice loss. A glacial lake outburst flood devastated Sikkim in India. Swiss glaciers lost 10% of their remaining ice over just two years. Sea ice around Antarctica hit all-time-low summer and winter records. Unprecedented fires raged across Canadian permafrost. Parts of the Arctic and North Atlantic saw water temperatures 4 – 6°C higher than normal. It rained far inland on Antarctica, and Greenland saw its second-highest surface melt ever.
Our message — the message of the Cryosphere – is that this insanity cannot and must not continue.
The Cryosphere – Earth’s ice sheets, sea ice, permafrost, polar oceans, glaciers and snow – is ground zero for climate change. This is because of the simple physical reality of the melting point of ice; or in the case of our rapidly acidifying polar oceans, the amount of CO2 in the atmosphere absorbed and turned to carbonic acid.
The warming impact of CO2, around 80% from fossil fuel use, already has led to steep glacier and ice sheet loss causing global sea-level rise; reduction of water resources from snowpack; growing CO2 and methane emissions from thawing permafrost; dramatic reduction of sea ice, now alarmingly low in both polar oceans; and growing evidence of stress on keystone polar marine species, such as krill, salmon and cod, from polar ocean acidification, warming and freshening. Enough. It is time to carve a line in the snow: because of what we have learned about the Cryosphere since the Paris Agreement was signed in 2015, 1.5°C is not merely preferable to 2°C. It is the only option.
Otherwise, world leaders are de facto deciding to burden humanity for centuries to millennia by displacing hundreds of millions of people from flooding coastal settlements; depriving societies of life-giving freshwater resources, disrupting delicately-balanced polar ocean and mountain ecosystems; and forcing future generations to offset long-term permafrost emissions.
This continued rise in CO2 is unacceptable.
The melting point of ice pays no attention to rhetoric, only to our actions.

“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 (BBC Interview / MP3 Format) 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.
On November 20, 2023, the UN’s Emission Gap Report found even if countries carried out their current emissions-reduction pledges, the world would likely continuously exceed +3C degrees of warming this century. Later that day, the International Cryosphere Climate Initiative released State of the Cryosphere Report 2023 saying, “Two degrees is too high. Our message — the message of the Cryosphere — is that this insanity cannot and must not continue. The melting point of ice pays no attention to rhetoric, only to our actions.”
Human induced climate change is an exponential component of an unordered system (chaos theory).
The Age of Loss and Damage is a new way of thinking about economics by combining economics, climate science, statistics, and physics. Until now, economic models have been unfit to capture the full extent of climate damage. Traditionally, “integrated assessment models” (IAMs) were used to forecast “shock” events. IAMs use “quadratic function” to calculate GDP losses by squaring the temperature change, yet ignore other methods (such as the exponential function) that are better suited for rapid change. “Climate change is fundamentally different to other shocks because once it has hit, it doesn’t go away,” said Thierry Philipponnat, author of a report by Finance Watch, a Brussels-based public interest NGO on financial issues. “And if the fundamental assumption is flawed, all the rest makes little sense — if any.”
Reuters reported, “Critics say this (IAMs) choice is doomed to underplay the likely impact – particularly if the planet hits environmental tipping points in which damage is not only irreversible but happens at an ever-accelerating rate.” Thierry Philipponnat’s report, Finance in a Hot House World, concludes: “Climate risk is growing to disruptive levels throughout the financial system and the guardians of financial stability urgently need to adapt their tools to regain control.” The report calls for economic models that do not mislead, scenario analyses that prepare the market, and a new prudential tool to address the build-up of systemic climate risk.
Traditional economics is based upon the “costs and benefits” to society. Since there are no known long-term benefits of climate change to society, the Age of Loss and Damage economics focuses on the exponential costs of climate change to society.
Health and Wellness
Humans will experience greater loss and damage to life and quality of life from air pollution, decreasing supply of potable water, extreme weather events, and disease. The greatest short term climate change risk to human health is deadly humid heat (wet-bulb temperature).
Real Estate and Infrastructure
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.
In October of 2023 climate scientist Sidd Mukherjee said, “Now I am thinking the violent rain will be a bigger problem before we die… still thinking it through. In the long run, yes, 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.”
In the spring of 2023, the USA suspended their national debt ceiling. Included in the debt ceiling suspension is a provision for unlimited emergency federal spending. The result is the government can continue to ignore the causes of climate change and instead give trillion-dollar subsidies to the fossil fuel industry through emergency disaster relief. Yes, another vicious circle — more fossil fuels subsidies result in more climate catastrophes resulting in more fossil fuel subsidies, etc. The end result will be additional trillions in government borrowing while the standard of living declines.
According to NOAA, in 2023 (as of November 8), there have been 25 confirmed weather/climate disaster events with losses exceeding $1 billion each to affect United States. These events included 1 drought event, 2 flooding events, 19 severe storm events, 1 tropical cyclone event, 1 wildfire event, and 1 winter storm event. This is the largest number of climate disasters recorded with a notable increase in extreme precipitation events.
Law Suits
What will create the change needed? Loss and damage litigation against oil companies and governments will change world economics.
The oil industry is going to be like the tobacco industry. The consumers are going to claim they were misled about the dangers of burning fossil fuels and will file lawsuits against the oil companies. You will not be able to buy oil or get insurance at a reasonable price (similar to what happened to cigarette smokers.)
Children have filed lawsuits worldwide against their governments over their basic human rights. A district court judge ruled in Held v. Montana that Montana’s Environmental Policy Act, which prohibits the state from considering the climate impact of proposed energy projects, violates the “right to a clean and healthful environment” promised by the state’s constitution.

Tipping points are Critical Milestones that directly impact the rate of acceleration in climate change by multiplying the number and intensity of feedback loops.
Push a glass toward the edge of a table and eventually it will fall off on its own. No matter how slowly or meticulously you push… no matter how you weight or fill the glass, it will reach a tipping point and fall off before being pushed completely off the table. No matter whether you believe the glass is half-empty or half-full, when the tipping point is reached it will plummet out-of-control to its end. This is science not fate, faith, nor belief. Human induced climate change has resulted in environmental tipping points being breached.
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
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”
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.”
The average temperature for Brazil had been above the historical average from July through October of 2023. Rio de Janeiro recorded 42.5C on November 12, 2023 (a record for November) and high humidity on the 14th meant that it felt like 58.5C, municipal authorities said. Deadly humid heat is the greatest short term climate change risk to human health. On November 17, “a young Brazilian fan of US singer Taylor Swift died in Rio de Janeiro after falling ill inside the sweltering stadium where the superstar’s concert was held, amid a record-breaking heatwave across large swathes of Brazil,” as reported by ABC. “The show took place on the same day that Rio recorded its highest-ever heat index reading, which combines temperature and humidity, at 59.3 degrees Celsius (139 degrees Fahrenheit).”
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.
