The AMOC Might Be WAY More Unstable Than We Thought...Here's Why

Take the PBS Digital Studios Audience Survey: to.pbs.org/202...
There is a mysterious cold blob in the North Atlantic that could be a warning sign that the largest heat transfer system on the planet, the AMOC, is on the brink of collapse. But it turns out that the AMOC’s collapse is a highly debated topic among scientists - climate models are inconsistent and there isn’t enough observational data to determine a trend. So, perhaps the answer to understand a possible AMOC collapse is to go back in time.
In this episode, we talk to three paleoclimate experts who look at the Earth’s past climate and find some really shocking things about the AMOC’s past behavior. And it turns out that the mysterious cold blob may actually be a bigger deal than we realize…
Weathered is a show hosted by weather expert Maiya May and produced by Balance Media that helps explain the most common natural disasters, what causes them, how they’re changing, and what we can do to prepare.

I'm an oceanographer. My research was done in the arctic ocean studying sea ice and heat budgets. The concern about AMOC slowing is what it means for the southern ocean. The conveyor belt (as it is colloquially known as) is more than a heat distribution mechanism for the planet. It also distributes nutrients. As AMOC sinks, the North Atlantic Deep Water (NADW) forms. This flows southward and eventually starts to upwell in a region called the Antarctic divergence. This upwelling brings in nutrients that in essence fuels the southern ocean's food web. This is why it is so productive and you have all the krill, baleen whales, orcas, etc, etc. A slowdown in AMOC will result in a slowdown of nutrients upwelling adversely impacting this ecosystem. HOWEVER, recent research have revealed what the potential mechanisms for a complete collapse of AMOC would look like. It is not just the melting of Greenland's ice. This melting does indeed slow down deep water formation. But to completely stop deep water formation, a sudden large volume injection of freshwater needs to happen and happen quickly. Melting of Greenland's ice does not achieve this. As the ice melts, there is mixing, the fresh water gets entrained, but regional currents move this water westward (causing sea level rise along the eastern seaboard of North America). What these new researches found was when a huge amount of ICE breaks off from Greenland, then carried south by currents where they then melt at once, it is this shock to the system that can stop deep water formation. As Greenland's ice melts, the likelihood of huge chunks of ice breaking off continues to decrease. Therefore, this mechanism is unlikely to occur. To determine and measure this mechanism, the researchers used isotopes of Thorium to make these assessments. A second mechanism is a sudden flush of freshwater into the North Atlantic. About 13k years ago, there was a lake in North America called Lake Agassiz. It formed due to the ice sheets melting back. Then around 12k years ago or so, there was a sudden influx of this freshwater into the North Atlantic and it is thought to have contributed to the Younger Dryas era where ocean circulation was disrupted and planet wide temperatures cooled considerably. (This is the 12k years ago period referenced in this video). There is a possibility for a similar situation happening today. In the arctic ocean, there is the Beaufort Gyre. It is an anticyclonic (clockwise) gyre which means there is a concentration of water in the middle (with subsequent downwelling). Due to increased riverine inputs, increased precipitation, loss of sea ice, there is a buildup of freshwater in this gyre. A new oscillatory system, the Arctic Dipole (of which I was a part of in discovering and describing this system) controls whether or not sea ice continues to flow within the arctic ocean or is pushed out through the Fram strait. Right now, this freshwater buildup is contained. If conditions change and become just right, this freshwater in the arctic ocean can be rapidly introduced into the North Atlantic. This would be the necessary shock to stop deep water formation. This is what people need to be keeping close tabs on. I do have my own channel here where I discuss many of such topics and have posted recent videos of this over the past several months.

[@0topon]

First i was relieved that a collapse is not possible and then you hit me with Beaufort Gyre

[@unadultratedtrini]

So I should infer that a collapse could be beneficial as it may trigger a global rapid cooling of the poles while a heating of equatorial regions. Though in the short to medium term this could dramatically disrupt food cultivation as it will eliminate monsoons until the system basically self resets after the rapid cooling period. The issue is with our current rate of additional heating, does this offset the collapse? Can offsetting the collapse and reset actually present more of an issue towards long term survival than that short period of rapid cooling and disruption to food cultivation resulting in the same collapse but at a point where the rapid cooling doesn't take effect due to the excess heating. (Facts to be observed, if AMOC collapses, poles will rapidly cool during their winter periods due to the massively reduced sunlight; the counter will happen at equatorial region as it will begin to rapidly warm and not be regulated with precipitation taking places that are naturally well suited for farming to become deserts (given enough time))

One of the things I'm personally doing is creating water harvesting earthworks in Greece! We are about two weeks away from planting out our food forest. When the swales are full, we can slow, spread and sink 50,000 liters / 13208 gallons of water, recharging the aquifer after giving a good drink to our fruit trees. I am also planting a whole bunch of support species such as acacias, vetiver and willow in order to create biomass that will further absorb carbon.

[@johnwang9914]

​@@JBaxter-pi8oj Most water harvesting strategies are to control and reduce the surface flow by topology and permeable materials. The idea is to let the water soak into the ground to rejoin the shallow underground acquifers rather than erode the surface and flow away. Swales are basically channels of rocks and pebbles into which the water would flow and it's speed reduced as well as directed into low lying areas where it should soak in, think of them as a French drain or ditch. In India, there's an ancient practice of piling up the soil in chevrons against the natural flow of the water on the surface so they slow down and have a chance of soaking in. If we used permeable pavements on our streets, sidewalk and driveways, a lot more water would soak into the ground to replenish the aquifers. Of course, these are just the shallow aquifers and hence more likely to absorb pollutants. Permeable surfaces are certainly important but offers little mitigation against the probable climate changes from a cessation or slowdown of the AMOC and an AMOC slowdown would likely result in more snow and frozen soil moisture accumulation in the northern hemisphere as less heat is brought north hence the benefits of shallow aquifers accumulation might actually become a moot point. Shallow acquifers aren't really sufficient to buffer the changes in precipitation and snowmelt, it's just something we could do something about. By all means, we should try to harvest water wherever we can but really it has little benefit with AMOC concerns.

Back in 2015/2016, I was part of an Internnational Arctic Circle Traverse team. We setup the largest Firn Compaction network in history - 13 sites across the entire Greenland icesheet. We were trying to help NASA determine why we were experiencing a significantly accelorated melt beyond what the current models had predicted. We setup data stations, did firn compaction readings, setup Thermister strings 65 feet into the ice sheet, multiple ice core samples at each site, did vacuum measurements, setup radar to track the ice melting through the ice layers, chemical anaylsis of each core back 30 years (10 cm chunks), checked surface reflectivity, and monitored each site's movement using hyper-sensitive GPS tracking. We confirmed there were giant shelves of monophorus ice that were stopping the snow from being absorbed into the sheet and forcing the new melt water to exit off the the icesheet on the surface instead of it's normal absorbtion cycle. We did the same chemical measurements on our ice cores (going back 30 years).

ive seen this amazing work, bravo to you all. be well thank you all

[@hilltigger]

@@OkieJammer2736 This is a long-winded answer because the effects are complex and ripple across the globe in multiple ways. Firstly, the arctic ice sheet won't be able to repair the ice lenses that have formed for decades to come. That damage has already been done, to be frank. Time and carbon polution-reduced atmosphere is the only healer. Locally, the ice sheet is "super lubricated" underneath causing faster movement combined with significant 7x normal run-off. The core damage is already done. We are already seeing some of the effects in increased and stronger weather events due to increased and more frequent carbon overloadiing of our oceans and in turn, clouds absorbing more warm air over the oceans. The most critical effect of the ocean's warming is the effect and ripple effect of it's effect on plankton, the ripple effect on the ocean's food source for much of what the ocean's creatures eat and also it's affet on land animals. Ocean's water levels in the southern hemisphere will increase due to the moon's gravitational force on our ocean. We expect the shifting jet streams to cause instability in weather causing incereased and exagerated droughts. The human effect - Currently, we have a problem of human ego (We can't possibly be affecting the entire planet. This is a normal cycle that can't be stopped.), Greed (Oil and Gas and iit's industries spreading misinformation to distract from it's affect. It's the cows, volcano's, etc that are the poluton. Not us. Don't look here). Ignorance (It's not warmer here. It's colder. The ocean looks the same to me.). What we choose to do as a species will either allow us to recover from what we have already done, or feel earth's inadvertant wrath, to be blunt. The two major absorbtions of carbon polution are trees and the ocean. It's not enough to simply use more effecient forms of energy that are available. How quickly we respond to this crisis will exponentially affect the future generations of everything, either positively or negatively. The ice lenses will eventually be buried deep enough into the Arctic icesheets and lose their effect on the water loss. However, that process can't even start to happen until we reach a balance point of the oceans' and trees' ability to absorb the excess carbon.

An article in Scientific American magazine (1970's?) explored the science behind the 'radiosonde' buoys used to map ocean currents. This mapping program was to determine transitions in temperature, salinity and other factors. The authors stated that such transitions were natural 'hiding places' for submarines....sound waves bounce or are refracted by said transitions. Regular mapping of the currents was necessary, as they changed over the seasons. Almost as a footnote, the author noted a weakening in the 'transporter current' that kept central Europe from freezing. 'They' saw the trends over 50 years ago, hid it under Defense.

[@grinner68]

As a scientist studying AMOC (and in agreement with those scientists who did not want to be interviewed - I’m pretty sure I know who they are), I found this report to be highly biased. Yes, some climate models indicate a 50% slowdown, but just as many indicate no significant change. And higher-resolution models which get the physics of the Southern Ocean and eddies correct don’t suggest much of a slowdown. And AMOC is controlled as much by physical wind-driven upwelling in the Southern Ocean and tropics that is not modeled well in many low-resolution climate models. Also, the idea of a “collapse” comes from model runs in the 1980s that were significantly biased because the salinity and temperature of the North Atlantic was not close to correct. I suspect many people referencing the paper as proof of a “collapse” have never actually read it. Look it up yourself and decide for yourself. Manabe and Stouffer (1988) Two Stable Equilibria of a Coupled Ocean-Atmosphere Model. Journal of Climate, Vol 1, pp 841-866.

[@leighanddansinclair1696]

But isn't the whole point that the patterns emerging in the temperature anomalies of the North Atlantic are reminiscent of the cooling patch that an AMOC slow-down would produce. This is *despite* the (modern) model predictions suggesting that no major AMOC slowdown should be happening at our current warming. We both know that models are not perfect and unrecognized model biases could mean that we've underestimated the sensitivity of the AMOC to perturbation. If this is true (and I agree - it's early days in trying to determine from short noisy observational datasets if this is indeed what is happening), then a major slowdown of the AMOC could have big consequences over the coming decades.

[@SammytheStampede]

I'm of an opinion (not asked for assuredly) that a great chastisement is about to be poured out upon mankind. This is but 1 facet of the catastrophe cycle.

Reducing emissions is only part of the solution. I'd like to see a show on reforestation of land and sea.

So we concentrate on prairie grasses, regenerative agricultural practices, and selective logging and replanting.

Don't get me wrong, humans got some problems with environmentalism, like monocropping, glyphosphate, land use, etc etc ... CO2 is not likely a problem. Tippinging points likely cause a correction back to the normal state of the earth, which seriously more icy cold than anything. Besides, look at CO2 atmosphere concentrations. Everytime they get high.... An ice age comes and they drop. It's almost as if the CO2 concentration _causes_ the ice age to occur.

So it is limited to that particular issue.

[@JBaxter-pi8oj]

Reforestation is an excellent idea as it allows nature to take the lead in healing itself. I believe the Japanese experienced the results of deforesting an island that was previously rich in organic matter and the effects of deforestation were that the land could no longer produce "food". Interestingly, it also impacted the ocean in the vicinity. And that included marine life. I recommend the work of Dr. Suzanne Simard, Julia Beresford-Kroeger and Peter Wohlleben for further information.

[@Peregringlk]

But can we keep up with the rate of emissions? I mean, if I'm not wrong, the Amazon forest removes from the atmosphere about 2 gigatons of CO2 each year, but we emit like 38, which are 19 amazonias each year. I know that I'm not accounting for biomass etc but my point is that the amount of CO2 we are emitting is no joke. Your approach feels "too slow" proportionally speaking. And if we account for biomass, according to chatgpt the amazon stores like 900 gigatons of CO2 at most, which equals to 25 of emissions at the current year. In other words, we would need to create four full replicas of the amazonia each century to keep up with the rate of emissions.

I never would've thought that the AMOC was critical for monsoon seasons in China and India. I thought the AMOC was just a North Atlantic climate thing only.

[@leighanddansinclair1696]

Water has an incredible ability to absorb and transport heat. The AMOC carries gargantuan amounts of heat from the tropics to near the polar regions. Now, warm surface temperatures cause air to warm and expand (becoming low pressure regions). Cold surface temperatures cause air to cool and contract (becoming high pressure regions). Air tries to flow from high pressure regions to low pressure regions, which results in our winds and weather. When you change the AMOC, what you do is cause a major change the pattern of surface temperatures. Changing this pattern of temperatures changes the location and direction of winds, and therefore changes the location and strength of things like rainfall regions. These effects can occur far away (literally on the other side of the planet) from the north Atlantic.

The oceans have impacts around the world, little if anything is isolated. That's why you hear about El Nino and La Nina near the equator having precipitation and temperature impacts thousands of miles away since it can change the air circulation patterns.

Right now I am most excited about geothermal power. I just find it to be a very elegant method of producing energy. Just drill a hole deep enough, lower some pipes, add cold water and get very hot steam, run it through a turbine, use the remaining heat to heat homes. Together with wind, solar and a few flywheels we should be able to cover most of our energy needs.

[@roughroadstudio]

We need wave action generation as well.

[@karenneill9109]

In our area (west coast of Canada), they use geothermal for heating and cooling. It’s too difficult to drill deeply enough to produce steam, but it’s real relatively easy to set up enough temperature differential to heat homes in the winter and cool them in the summer.

[@IdrisFashan]

I’m in Alberta, Canada and our government committed $50B to geothermal industrial development. We have a lot of oilfield drilling skill here, so it is a very exciting time for a lot of engineers and technicians here. Geothermal is a great fit for energy transition from on-shore oilfield work! Geothermal gets pretty complicated, as does anything 20 feet below ground or more: hydrology, rock formations, soil type, pressure/heat management, corrosion, etc.

Look at New Zealand. 90% of the country is powered by renewable energy. Geothermal is big down here along with hydro and wind.

Eliminating human emissions is required for many other climate related solutions, so let's do that anyway.

[@gammayin3245]

As an advocate of ecosystem sustenance for all of life, I recommend that current agricultural practices change so that soils can rebound with native mycorrhiza and fertility, and so that ecosystems can revert to fully supporting native plant and animal species. Practices include water harvesting, sustainable grazing practices, keeping the soil covered with plants, permaculture and creating 30-50 ft. wild zones (akin to British hedgerows) between fields and property boundaries, and wider wild zones (200 ft or more each side of a river, lake or stream) in all riparian areas. These practices allow farms and ranches to become important carbon sinks which help curb climate changes and halt the diminishment of species. Also, ag practices of pesticide, herbicide and fungicide uses that damage internal organs and biological systems need to be halted to clean up waters and produce foods that are non-damaging to health. Ag practices need to reflect the climate in which foods are grown such that extra water and other resources are not necessary to produce foods. This will restore ground water levels and natural stream and river flows. Also these techniques utilize fewer fossil fuels which all add to global climate changes. In areas of higher wildfire dangers, goats and sheep need to be herded over these terrains every spring and summer to lessen the fuels and thin forests to make them less prone to catastrophic wild crown fires. Reducing catastrophic crown fires also counterbalances climate change.

My conclusion: we are doomed, not to extinction but to drasticly reduced quality of life due to extemes of climate, first heating that will displace large populations due to flood and fire and cause increased costs in goods and loose of insurability. (Later by the AMOC collapse perhaps) More imigration and reduced food and land resources leading to stresses on democratic institutions and less international cooperation. All favoring greater autocratic governments and more war. Humans will adapt but at a cost to civilization and population. Perhaps this is the "great population reset" needed for the next (22nd) century. This is based on 1) the fact that climate change first discussed in the late 1980's when atmospheric CO2 in 1990 was 354 ppm. This is now over 420 and rising every year by 1 - 2 ppm. In 1990, CO2 emissions totaled 19.5 GT. This is now over 36 GT. (Pre industrial atmospheric CO2 was 280, and emissions in 1940s was less than 5 GT) 2) during the covid year when basicly the entire world economic activity was drasticly reduced, the Amospheric CO2 continued to rise but at a slightly lower rate. CO2 emissions did fall by 1.9 GT between 2019 and 2020. But atmospheric CO2 continued to rise. 3) Humanity will not tolerate economic slow down of the covid years as a perminant condition. 4) even if we have Zero increase in emissions, because the half life of CO2 is measured in over a century,which means that for at least a generation or two, Climate change will continue. 5) feed back loop-processes progressing toward their feed back point: loss of arctic ice, wild fires (contributing to greenhouse gasses and soot spread by wind to fall on glaciers facilitating melt), and permafrost melting.

[@leighanddansinclair1696]

There are natural cycles. The major ones currently operate on 100,000 year timescales. The last 10,000 years has been remarkably stable, allowing human civilization to develop. But much of the preceding 90,000 years was characterized by major climate instability that would have disrupted any fledgling civilizations. Calculations suggest that our current *stable* climate could persist for another 10,000 years, but this stability is *fragile*. Theory and observation tell us that our climate system is 'twitchy', responding suddenly and unpredictably to perturbations. Rising global temperatures caused by greenhouse gases represents a major 'kick' to our climate system The physics is simple and clear. Regardless of whether CO2 has previously been a 'driver' of climate change in the past, or an 'enhancer' of climate changes triggered by other things, the 50% increase in CO2 over pre-industrial levels (to levels not seen in over 3,000,000 years) *will* perturb the finely-balanced energy budget of earth's surface. Nobody knows for sure what this warming will trigger, but we know enough to make educated guesses, and there are scenarios - like a slowdown/shutdown of the AMOC - that lead to a world characterized by rapid climate *instability*.

The result would be chaos.

[@EchoDoctrine]

Yes Two things: 1- the earth going through those past cycles took millions of years. The cycle took millions of years of to slowly change BUT we humans are doing it in mere decades. The amount of change we are pushing into our atmosphere and world is off the charts. You can disbelieve or laugh at this but you might see it & finally understand in your lifetime (depending on your age & all that) 2- yep the earth changes, it’s changed before so no big deal right? WRONG !! When this changing happens crops won’t grow where they used to, massive food crops will be wiped out. Now growing seasons are being messed up, every year we hear more stories of “oh darn the Georgia peaches or Florida Oranges had the worst growing season ever because storms were very different than before”. Too much rainfall all of the sudden after weeks of drought lead to a massive reduction in ______ (fill in the blank crop this year). That story repeats again and again. The planet will go on. But YOU humans will have a hard time when the food can’t be grown as easily, when the food shortages lead to famine, war and chaos. But hey, you sound like the type of guy that laughs & scoffs at “the professionals”. What do they know. You were so smart in school. You do your own research. Good luck buddy.

So 2 mile thick ice sheets melting between 15-12k years ago releasing enough melt water to raise global sea levels by 400' didn't cause the AMOC to stop but the current melting in ice sheets with indistinguishable sea level rise is causing it to stop. That is much like the melting permafrost consisting of preserved plant matter being a net carbon emitter rather than a net carbon sink despite the conditions being present that caused the plant matter to be deposited there in the first place providing the source of the carbon emissions now.

[@markdormer7959]

the following is more serious than cynical, but there are a few things that have got me thinking: - If the AMOC keeps collapsing over millions of years due to global warming, without us, then how does us our CO2 materially change the cycle? - If the heating of the AMOC, thereby causing it's collapse, encourages global cooling, then what is the major concern of us being within an interglacial warming period, which again happens with or without us? - CO2 being the main input source for plants and green life on the planet is also produced through the natural breaking down of methane. Methane being the major output of biological decay, creates CO2 which is absorbed by plantlife, which create fruits/veg/nuts/pollen, etc, etc....and some of the largest zones for this are monsoon flood zones/flat-lands....is this show insinuating that we need to reduce floodlands used as a significant part of our delicate eco-system by reducing rainfall?? - Is it just me, or does the video really just confirm that the planet is in constant flux, and we (as a race bent on survival at any cost) don't want to face the inevitability of the next pending move in the constantly advancing natural global adjustment and are therefore striving for solutions to fight against nature ?? (that we basically cannot accept that the world is changing regardless of our efforts, and that we, in the delusional belief that our species is eternal, need to fix the planet???) I was always a bit 'on the fence' when reading how farming is a high carbon industry, when I also realise that vast acreage is destroyed on a regular basis for development of more industrial zones...the same green acreage that would have been absorbing the carbon output from farming.........natural carbon capture plants. This video about the AMOC , I think, just swung me into the inevitability of our situation, no matter what we do. Our collective output has a micro-fractional impact on the natural order of things, and coupled with the weakening magnetic field (which also causes heating through increased solar radiation) the next stage is coming, and mining heavy metals to create electric cars, flying fruits and vegetables all over the world, and recycling your tinfoil hat wont change a thing.

I’m from the UK and what terrifies me is that after 10 or so years of looking into renewable energy sources and finally seeing the light on moving away from fossil fuels some countries are starting to get governments that are climate change denier’s and want to reintroduce our reliance upon fossil fuels. However there are also some countries that are more than happy to buy Oil, Gas and poor quality coal from countries that are under restrictions and are exporting to countries like China, India and some Eastern European countries which are getting these fuels at a discounted price. Wa also have countries that have a vested interest in selling fossil fuels to stay rich and relevant energy providers. For example Russia is currently producing some of the dirtiest coal in the world and exporting it to whoever is willing to buy it at a huge cost saving, however the countries that are buying it are using it to produce cheap electricity for their expanding energy requirements for their expanding economies. Until the world is willing to invest in renewable energy we are just going to destroy our environment and by then it will be too late. Heck even the UK no longer uses coal to produce electricity.

[@Les_S537]

There is no "too late" in this discussion my friend.

Will the road be a little bumpy? Sure, but man made climate change is NOT going to be the end of the world.

[@donaldhester6555]

If I am getting this correctly, you think that the AMOC is slowing due to global warming because of CO2 emissions, but once it slows or stops, the earth will begin the glacial cycle that is going to happen anyway and the earth will get dramatically cooler, affecting rainfall, which is going to come in areas previously not getting much creating more methane. If this is true, wouldn't this also prevent methane now rising fron areas where permafrost is thawing? Wouldn't cooler northern European temps also cause the Greenland ice sheet to reglaciate instead of melting? That sounds alot like a loop of warm and cool periods. One thing is obvious in this video, and that is the fact that we are nearing the end of a warming period that is a natural cycle and we still are several degrees temperature below the last warming cycle. I think the Milankavitch cycles are the most dominant factor while you never mentioned that at all, as if it doesn't exist.I suspect that the AMOC will cycle more rapidly if what your evidence provides is correct but will eventually reach a point where the Milankovitch cycles make it a permanent cooling until the next interglacial rather than expediting the next glacial period of the current ice age. Trust me, you do not want to see another deep freezing glacial period where the ice is many miles thick and most of earth is covered in ice, but history shows that it will happen. Humanity needs to plan for this with every modern technological advantage we can muster. I also do not trust any science that does not include the amount of CO2 produced by breathing animals such as 8 BILLION humans. I need to see and hear from scientists who account for all factors rather than just CO2 and wild predictions that exclude all other factors. For example, If CO2 that represents about .04% of the current atmosphere is such a driving factor, what caused the melting of the glaciers before mankind even existed? Where did such an enormous amount of CO2 come from to cause warming enough to cause the current interglacial warm period? The answer is there, but scientists affiliated with the IPCC are not interested in anything that could stop cash flow to them and their never ending studies on CO2. They really should get to the bottom of what created all warming and cooling periods.

[@cyber5515]

"I think the Milankovitch cycles are the most dominant factor". I agree. Plus, the ice core data shows that when the temperature drops, due to the Milankovitch cycles, the ocean dramatically absorbs much of the CO2 in the atmosphere. By destroying the entire fossil fuel industry, our ability to put some CO2 back to keep the planet warm is gone.

In my book political isms should not be a part of the task to get our world transitioned to an emission free energy production and usage. No matter if anyone are on the left, centre or right political spectrum, they need a planet with clean air to breathe, waters that are healthy and filled with life and an unpolluted landmass to live on. Glaciology now scientifically have documented our atmospheric carbon content, YEAR BY YEAR 1,1 million year back, thus we know the conditions that paved the way for our creation. It is in itself remarkable that we can do that, considering it´s only 65.000 years since we left the African continent for the first time. This insight have told us, that there have been cyclic slow climate changes happening before but that these have not really affected the atmospheric carbon content much. However 3 times in the 1,1 million years, large widespread global volcanic eruptions have made sudden changes in our atmospheric carbon content with up to 30 PPM over the otherwise relative stable 220 PPM the planet´s regulating systems prefer and try to seek back to, and EACH time it have triggered abrupt climate change. Since around 1880 and until today we humans have caused the atmospheric carbon content to go up with over 200 PPM! Our atmospheric carbon content do not care what corrupt people agree behind closed doors at shady meetings, it´s simply responding to the massive amount of greenhouse gasses we spew out. In this very matter we all are in same boat. I am a strong believer in democracy. The problem I see in to many nations that call themselves democracies, seem to be that the fossil fuel industry have managed to corrupt politics and those operating in politics, in ways that have short circuited democracy, helped by a media landscape supporting the lies and dis and mis-information. I do not think it are a coincidence that the 4 nations where Murdoch media have significant market shares, Australia, USA, Canada, UK also are the large nations with highest greenhouse gas emissions per capita. What we globally should be doing RIGHT NOW is to be in the middle of an "Apollo program" effort to make a fast transition to emission free energy production and usage, simply driven by our understanding of the urgency our current situation dictate. It would, on top, create massive growth and prosperity around the world but do so sustainably and provide the foundation for a circular economy. If we do not urgently get our planets temperature down, we have entered the beginning of the end of a world remotely recognisable, to what we know, will allow humans, the species we share the planet with, the fauna in air, on land and in our waters to exist. Mars lost it´s atmosphere and in the end, the same can happen here, although I suspect we will be long gone by self eradication before. The future that have begun will come with massive random disruptions caused by extreme weather and it will randomly take away peoples livelyhood and traditional living conditions. WE NOW have ALL the knowledge and technology needed to make a complete and fast transition to an emission free energy production and usage. Our grandparents can be excused since they did not know the consequences of their actions. Our parents should be ashamed for not acting in time but WE have full insight and the solutions and thus we truly now act as the ultimate morons. If there will be any left to write history books we rightfully will be judged harshed. Name one other mammal that knowingly and deliberately destroy the very habitat that provide the foundation for it´s existence. Our house IS on fire and currently the consensus seem to be that massively pouring fossil fuels on the fire miraculously will make the fire go away.

The resolution pointed out that city staff should inform local residents and the medical community about the risks of traveling to China for organ transplants, in order to help prevent local citizens from becoming unwitting accomplices in China's state-sponsored forced organ harvesting from prisoners of conscience. Vice Mayor Pamela Sebesky (second from left) presents the resolution to Falun Dafa practitioners during the City Council meeting. The city’s Vice Mayor, Pamela Sebesky, personally presented the resolution to local Falun Dafa practitioners during the city council meeting. She said this resolution is very important because it can remind and inform the public that such cruel persecution and inhumane things are happening. In her speech, Ms. Tang, a local Falun Gong practitioner representative, thanked the city councilors for their support of human rights and religious freedom. Ms. Tang said that this action is particularly meaningful as the holiday approaches, because the American people freely celebrate their traditional religious festivals, but Falun Gong practitioners in China face imprisonment, torture and death because of their beliefs. She added that this courageous resolution will bring blessings to the residents of Manassas. Falun Gong practitioner Wang Chunyan, who has personally experienced the persecution in China’s labor camps, and who worked with the city to pass the resolution, said that in China, the CCP’s persecution confuses people’s perception. She told of her personal experience to the American people in order to let them know that there is still such an evil regime in the world that harms people. Ms. Wang said that righteous people should work together to oppose and stop this persecution, so that mankind can return to normality. Currently, the Virginia House of Delegates and 25 counties have passed similar resolutions in the past two years, and the Governor of Virginia and five cities in the state have issued proclamations or resolutions to support Falun Gong. Resolution from the City of Manassas The Resolution from the City Of Manassas states, “To raise awareness among Manassas residents and the medical community of the risks of traveling to China for organ transplants in light of recent reports of state-sponsored organ harvesting from prisoners of conscience. “in June 2016, the United States House of Representatives unanimously passed House Resolution 343, condemning the systemic, state-sanctioned organ harvesting from practitioners of Falun Gong and other prisoners of conscience. “Manassas residents should be fully informed of the organ source in China before they make the decision to engage in organ transplant tourism in China, and the Manassas City Council should assist in raising awareness in this regard. “Now, therefore, Be it resolved that the City Council of the City of Manassas hereby condemns the Chinese Communist regime’s persecution of Falun Gong, harvesting of organs from prisoners of conscience in China, and use of prisoners of conscience for slave labor in China.” Copyright © 2023 Minghui.org.

What I just realized is that temperature is relative. There will always be ocean currents even if the oceans heat up. Let’s say the arctics ocean heat up by 10 degrees above average, well that means that the waters in the equator will also be warmer than before. Which means that there will always be a dis balance in the ocean temperatures which will continue the the same flow as always. It’s like boiling water. Making the water hotter is not going to change the circular flow inside the pot. The heated water will rise and the water on top will return to the bottom.

One of most important things we can do to mitigate this is recarbonize the soil. Terra Preta del Indo (the anthropogenic "black soil" of the Amazon) was cultivated for millenia, and enabled the jungle to support a wildlife and human population it normally wouldn't. It's not merely biochar and compost; it's soil microbes that actively sequester carbon, which takes it out of the atmosphere and restores soil fertility in one go. Doing this at a large scale would boost our chances, far more than only planting trees!

If the consequences are slight, you can afford to take more risks. If the consequences are catastrophic, you can't afford to take any risk. If you get a recall on your car's brake lines - you immediately go get them replaced, since a brake failure would be catastrophic. Even if only 6% of people's brake lines are failing, you get it fixed because if you fall in that 6% you might die. If you get a recall on your car's ceiling light, though, you feel no urgency to get it fixed, because the consequences of it going out are minimal. A slight risk of a catastrophic event requires action, since even if the probability is low, the damage, if it happens, would be huge - a big risk of a minor event does not trigger that kind of response. The main problem with our political and economic response to the fact of global warming is that way too many companies and politicians are treating it as if it were a warning that the ceiling light might go out. In fact, of course, it's more like the brake lines are in danger of failing. We should act forcefully and immediately - but we're not. We're just not wired to understand probabilities and risk, and it may destroy us.

nyc Yes, well said. It is however, not that the brakes might fail, it’s that we know with absolute certainty they will fail, & soon, we just don’t know exactly when. In fact, we’re already having trouble stopping. And we can’t just take it into the shop because the manufacturer is lying, saying there’s nothing wrong.
