Negative carbon, Do you mean removing co2 from the armosphere, including at high elevations, where the level is less than 0.25 grams/m³, compared to sea level 0.49 grams/m³. At the Altiplano the grain producing plants are suffering from co2 STARVATION ,and so are the people. Do you even know what you are doing? about a million people depend on a meager ration. So that is carbon justice! THINK ABOUT IT. Better, go, fly to La Paz and see for yourself. It is a bloddy good Idea, as you put it!

[@xflyingtiger]

Before I offer my opinion on this, allow me to say that this is a great channel. Thanks for producing it. Now, my comments. A bunch of trees do not equal a healthy forrest. Forests are extremely complex, involving understory, canopy, mycelium complexes below ground, below ground and above ground microbe interactions (some of them taking hundreds of years to develop), and the interdependency of yet to be discovered systems that merely planting trees can never replace. Planted wooded areas, not being forests, usually result in less than optimal health for the trees, and can even lead to unforeseen consequences involving new ecosystem balances that might actually be harmful. Nature's interactions are complex beyond comprehension, but to comprehend we must at least try. Though we don't fully understand the process, we need to make an attempt to understand and replicate the actual forests that have been destroyed. But natural grasslands are equally important, and an entirely different subject. Trying to solve this problem with a capitalist system is questionable in my view. Out of control capitalism created this problem. Mechanically recapturing carbon in fancy new factories designed to operate at a profit is crazy. The best carbon recapture system ever devised is the process of natural photosynthesis on a massive scale. Our photosynthetic earth is crying out for help, that part of it that is still alive.

xflyingtiger Ok, great. Should we not plant trees then? I'm all for healthy natural forests, but if we don't get the carbon out of the atmosphere soon, we might not have any forests at all.

[@northavealum]

Before throwing the "capitalist system" in the waste bin, go take a look at the company "Nori" (Nori.com) that Dave mentioned - and look at how consumers (individuals, families, companies) buy carbon offsets and how suppliers (i.e., entities that extract and store carbon like Harborview Farms [one of Nori's suppliers]. After you've explore the whole solution end-to-end, I think you'll see that it is a capitalist solution that does what capitalism can (but doesn't always) do: identify a problem worth solving (aka an opportunity), develop a solution that consumers will purchase, and make a market. Also, go look at a company called IndigoAg and their project "The Terraton Initiative," which is designed to make a market to pay farmers en masse to change agricultural practices to drawn down and sequester carbon in the soil. "Out of control capitalism," in most cases was responding to consumer demand for products and services. If we're looking for someone to blame, we should look in the mirror. When it's 95 degrees outside and 70%+ humidity, I want to run my air conditioner. When I want to watch KZbin videos like this one about climate change and possible solutions, I power up my laptop and watch "Just Have A Think" - both those activities take electricity that someone has to generate. So, I'm part of the problem. Now - it's up to me, and millions of people like me, to demand a solution. Markets move at comparatively lightning speed when a legitimate opportunity (a problem to be solved, a need to be met) presents itself - governments, no so much. These days in the U.S., with Democrats and Republicans engaged in battle, even less is getting accomplished by government. Case in point - energy companies (like Dominion Energy in Virginia) are closing down coal-fired power plants much faster that the Federal Gov. would ever have tried because there's a cheaper way to generate electricity (thankfully that cheaper way is also cleaner than coal).

[@paintedwings74]

We generally re-use as much of the carbon-based material we encounter on a daily basis as we can manage, with the goal of increasing the soil health of our nearby woods and our garden. It's small-scale, but it's pretty cool. I feed my coffee grounds to fungi, harvest the mushrooms from the surface as it matures, and then bury the digested coffee and fungi in the garden soil. We compost with worms in the kitchen, then reuse that soil. But so far as actually trapping carbon, we have even more fun; the sawdust from my projects, the stems and pits and other hard plant material "waste" we generate, all goes into making charcoal. Then bury that charcoal in the garden, or sprinkle it in the woods, and it holds nutrients in the soil while not degrading into gaseous carbon for a long, long time. It isn't long-term, large scale carbon capture, but it could be. Our lakes produce massive quantities of algae, and 500 pounds of the stuff is equal to 1 pound of phosphorus fertilizer. Filtering out the algae would restore the health of the lakes; compressing and drying the algae into biomass cakes and then heating to off-gas hydrogen for fuel, you end up with a phosphorus-rich biochar that could be sold to farmers as not only a fertilizer, but a soil-enrichment that would help phosphorus to cycle within the soil rather than requiring constant artificial application. People aren't paying attention to this local level, small scale stuff, because it doesn't generate profit. But is it worthwhile to examine it for scaling up, to consider it a profit-neutral process that saves us from the run-away climate change we're on track to experience?

holistic grazing management is one of the management "systems" that with the help of animals can do carbon sequestration and soil improvement. We started converting to it a year ago and the pasture has never been better. This year i encountered way more mushrooms and frogs all over our farm, wich are good indicators for increasing health. Also the hight of the grass and the density of plants as visibly increased. All from moving 130 chickens a cow calf pair and a horse around on pasture and monitoring the grass that it doesn´t get overgrazed. Another farm i worked at is starting to implement it this year as well with about 22 hectars of grazing land and about 80 cow/steers. And they already had more peace of mind being able to better manage the animals in a holistic way. It can also be scaled up to whole communities of more than 400 hectars with a lot of regeneration happening and increased profits and a better way of life. For more information check out the Savoury Institute or Holistic Management International.

13:50 I'm more more skeptical about corporations trying to cash in the environmental movement and commodify pollution. I suspect it'll only lead to imposing further financial stress on the lower classes instead of actually doing much of anything. After all, the members of their executive boards will continue to fly around the world, live lavish lifestyles and maintain their huge carbon footprints. I always raise my eyebrow when capitalists lecture the lower classes on carbon emissions when they themselves are responsible for the vast majority of them.

[@northavealum]

I assume, based on your comments, that you don't support a capitalist system. Does that mean that you don't use the internet (oops, I guess you do), you don't use a computer, you don't drive a car or ride on a bus or train, and you don't buy your food from grocery store or local markets, and you don't use commercially produce medications / over the counter drugs, nor go to doctors offices and hospitals where doctors and nurses use computers and instruments to diagnose your health problems and treat you. Governments didn't make any of those things, companies and people did - and they did so to earn a living (i.e., make money). If you go study emissions data, you'll find that carbon emissions from "the lower classes" are not insignificant - ergo, they're part of the problem. I'm willing to bet that my electric stove is responsible for less CO2 than a kerosene cookstove in Africa or India or Southeast Asia. I too always raise my eyebrows - when people want to pretend that capitalism is the root of all evil. Just ask the people of North Korea, or read the diaries of people in Russia in the 1930s - 1950s. BTW - I wonder how many people were shot trying to escape TO East Germany.

So what if companies move to China, India, Mexico, or any other country? Yes, they move to save money. Not seeing a problem with that. In fact, it's a win for both the consumers and the producers. Workers have their benefits cut to the bone is somehow a problem? Do workers have a right to benefits? No, that is a luxury that the producers are giving their workers. Yet, since the government keeps writing and passing regulation after regulation, that puts a cost on the producer. Now, they can either raise their prices to keep those benefits, or they're going to have to cut benefits to keep products at a cost that the consumers are willing to pay for. Again, this all stems from government getting involved, not Capitalism.

Only carbon negative if you lock up that carbon for a significant amount of time. In other words convert it to biochar.

Water heating or even electricity generation could be added to such systems as well.

@@CarbonConscious Well, what you do with the carbon afterwards is up to you. If you want to open up the valve to drain the tanks to make room for the next lot (or burn the wood) then you're back to square one. Burying it, biochar, building then burying all work just so long as they're taken out of the cycle. Personally, I love biochar and it's a good way of using a byproduct but we urgently need to get started on this.

[@CarbonConscious]

​@@immortalsofar5314 When building with wood you store the carbon for whatever the average lifespan of wood is in construction these days, I'm sure it's below 100 years. If you bury or allow the biomass to compost then at least 99% will find it's way back into the atmosphere within a decade or so so that's far from long term storage as well. Biochar on the other hand can last 1000+ years and some studies even claim a half-life of 7000 years. Now that is something that we can call long term storage. The nice thing about biochar production is that it still enables us to make use of about 50% of the energy. On top of that the biochar can reduce other GHG emissions when it's added to the bedding of livestock where it will bind a large part of the methane and nitrous oxide emissions which then become nutrients for the plants in the soil where the biochar is applied. Making even more growth possible and setting a positive feedback loop in motion. I totally agree that we need to get on this with urgency. That's why I'm mentioning here that I have developed a very simple stove that can be used for domestic heating and cooking.

Plant trees for plantation wood. Build the wood into engineered beams to build multi-story quality buildings (and houses). This sequesters carbon for a long time. Pyrolize all the waste wood from the forest and from milling and construction, producing LPG, gasoline, diesel and air craft fuel, reducing the amount we have to take from the ground. Incorporate the charcoal which is a by-product from wood pyrolysis into agricultural soils to their benefit and sequestering more carbon. And, by the way, building with engineered wood displaces a lot of cement - itself a large source of carbon pollution.

When you focus on clean air and water we will get better results. An initial focus should be on cleaner power plants this starts with Natural Gas and sequestering any CO2 and it includes nuclear power plants and hydro geothermal. Wind and Solar because they are dependent intermittent power systems they could be used possibly more effectively to generate hydrogen fuels. Once we have established a working reliable clean power grid we can then increase electrification for vehicles and reduce petrol/diesel vehicles.

First off, I am a great supporter of your work and up until now I can't remember disagreeing on anything significant. However in this episode regarding offsetting I strongly disagree. The European Commission made a study in 2016 that found that 85% of claimed offsetting schemes didn't offset basically anything (Link at the bottom). Central points are lack of accountability and the question of additionality, last one meaning if the project of planting new trees is actually being done because of the offset-program or it would have been done anyways. Another problem being that the assumptions about a tree absorbing so and so much CO2 in a lifetime, more often than not being true, as 9/10 trees simply die young. The lack of accountability makes it a business ripe with fraud, or regions taking money to plant forests they would have planted for other reasons. A danish newspaper Politiken just revealed how this was the case with the vast majority of projects danish companies had been paying to reduce emissions in various regions of the world, one example being a chemical plant in Russia with high HFC emissions. They simply increased their HFC emissions and then reduced them again. In that vain I also find it questionably that you uncritically read the marketing material written on the offsetting companies websites, as there is now a lot of money to be made and if it sounds to good to be true, well then... However I would love if you did actually do a video with in-depth analysis of accountability and additionality. Where are all these trees which Ecosia and other companies planted? In the end I think the idea of paying off others to offset emissions is dubious at best, and catastrophic at worst as it will give a false sense of safety as we are not taking the necessary measures to curb emissions in our part of the world. Again, I really appreciate your work and I would love to hear your feedback. Cheers ec.europa.eu/clima/sites/clima/files/ets/docs/clean_dev_mechanism_en.pdf

Hi Kjartan. Thanks for your feedback. I agree with you about many carbon off set schemes (and indeed even country to country carbon emissions trading). Many of these have indeed been shown to be corrupt. It is worth keeping an open mind about the newer carbon negative schemes in my view. Only time will tell of course. All the best. Dave

[@kbobkpop]

​@Just Have a Think Hi Dave, thank you so much for your reply. I absolutely agree that we should keep an open mind about new carbon negative schemes, if we are to win this battle we have to fight on many fronts, and lot's of innovation is needed. It's just after following the debate for twenty years I've seen so many solutions being presented as being the next big fix. There was the big hype around biofuel from algae, which didn't really result in much in the end. BECCS and carbon-capture in other forms have also been talked about fro decades now with only negligible realisation in the real world. Then there was the idea of adding seaweed to cows feed, so they emit less methane, which I have also heard about for at least ten years. And the list goes on and on. All the while global emissions keep increasing year after year, so that we today emit around +80%(!) more per yar than when the IPCC was founded in 1988. In the end it just feels like a distraction from making the substantial structural change that is needed. I know you are making videos on a wide range of topics around climate change and the fight against i, which I really appreciate, and this was just one aspect of it. Some kind of overall review would be very interesting. Where have we actually succeeded in decreasing emissions, where not, which innovations worked out and which didn't, and possibly why. And of course accountability and monitoring of these schemes would also be very interesting, in fact so interesting that I will go see if I can find something on it now. Best Regards, Kjartan.

However, real markets driven by wind, solar and the ocean need to keep pace, so the emphasis needs to be on both. The future is created by every little decision we individually make - if you choose to drink your last days at the pub, then you are contributing to our last day as a future, being greedy and buying into these make believe eco markets will help create a future that our kids and their kids can live.

The most immediate and most certain pathway to human carbon reduction and the most cost effective, (to those that live and die by this metric) is to produce less and consume less. Less air travel, less beef, pigs, chickens, less cars, less planned obsolescence, less production and destruction demanded by the frivolity of fashion and human vanity. Unlike speculative technological fixes, this process of carbon reduction has been rigorously tested in real world circumstances most recently in 2008 without requiring the consumption or destruction of any blindfolds, cigarettes, priests or brick walls. Additionally, this pathway to carbon reduction lacks the uncertainty and consequent potential misappropriation of scarce resources as well as the long lead times and additional carbon expenditures. However the prospect of less is most threatening to those at the extremes of the income distribution curve. The poor and the impoverished regions of the world know that less means less for them than for others and the rich at the other extreme realize that less means less opportunity for extraction, exploitation and consumption upon which all profit is derived. The poor as the saying goes suffer what they must, while the rich prefer the less certain but potentially more profitable path of growth and applied technology carefully vetted by Wall Street financiers. And who knows, they may be right....in a couple hundred years the evidence will be clear.

Then you have strongly religious people that get angry over too many questions. Parents with naughty kids will see an angel who has every right to hit the other kids because all the other kids were being mean. I struggle to understand people like that, I struggle to understand anyone that chooses what to see or what to hear. If I'm ever proven wrong on something, I'm usually quite happy or impressed and attempt to correct my knowledge on the topic. But my husband will aggressively defend an opinion even if he has little knowledge of the topic, usually needs 20 mins and a kiss before being able to explain why hes wrong and then hes happy to reconsider and seek evidence on the topic together. What can the human race possibly do to improve the inherent lack of understanding and knowledge in the world because most people base their knowledge on personal belief these days, its crazy, a modern medieval mess where scientists and learned people are attacked while idiots decide whats true and whats not and quickly the truth becomes hate speech, extremism or terrorism even!

[@scribblescrabble3185]

"I struggle to understand people like that, I struggle to understand anyone that chooses what to see or what to hear." I think there are several effects playing together. Two might be _cognitive ease_ and _having special insight_ . The first one, in short, is the rewarding feeling when thoughts seemingly fit together, that happens usually when already held concepts are being reinforced, usually by repeatedly hearing the same thing over and over over long periods of time. Sadly, reading scientific publication, especially not of ones field of work, rarely does that. So climate science might not lend itself to cognitive ease for the majority of people. There is also a book named cognitive ease, I think it revolves around using this concept in marketing. With the second I mean the feeling of having special insight others do not seem to see or (are unable) to understand. It gives someone a boost in self worth and self confidence. Both good feelings. Easy topic for "special insight", conspiracies. There are certainly more factors, like the _illusion of control_ . But I am not anyone with further insight into someting like that.

Consider that our heliosphere is crossing the galactic ecliptic as you read this there by destabilizing the magnetosphere of the planets and sun in the solar system in turn this is destabilizing the plasmasphere which couples directly to the ionosphere which drives the destabilizing jet stream causing it to be wavy. This then leads to uncertain and unpredictable weather. We are also entering another grand solar minimum. This increases cloud nucleation which as of 2020 has been allowed to be part of the 2022 ipcc climate models. Look for that. In short we are on the cusp of not only falling into another 200-plus year solar minimum but a 80000 year glacial period.expect rapidly moving magnetic poles, destabilization of the jet stream initially, then increased volcanic and tectonic activity. if you really care about saving the planet and humanity try doing something about the 700+ nuclear facilities that will abruptly go offline during the next Carrington event.

Ecosystem will always pay the bill. To solve CO2 emissions you get in order from easiest to hardest : 1- Do nothing (mass extinction will continue and end). 2- Cut all forests and use them to put CO2 underground, plant and start over (selective mass extinction, only humans and cattle left). 3- Stop CO2 emissions, plan a century long strategy to capture carbon, while preserving natural ecosystems (close call last-minute safe, Life in the Solar System remain feasible).

You are exactly correct: Planting a tree does nothing to mitigate CO2 in our atmosphere. When the tree eventually dies it decomposes (rots) and puts ALL of the CO2 back into the atmosphere. We need to cut down all the old mature trees, Carbonize them and bury thye carbon. We then plant new tree and recycle.

Any Destiny fans will very much notice the logo for Caíque Barcelos 😅 Rasputin is the answer to climate change... No but really, great video! Love Ecosia! Still a little hesitant about for forms of biomass and bioenergy used in this video though, given how algae seems to be the best alternative now. Some cities around the world like Chicago, IL stack functions by growing algae on top of waste water, purifying the water and cultivating algae that could be used as alternative fuels. Not very familiar with the carbon calculation on that one, but repurposing the Earth's surface area for multiple uses gives us a feasible chance at sequestering carbon. Lots of people still eat meat and dairy all over the world, products which agricultural lands are primarily used to create, and given that those habits likely won't change as fast as we want them to, the algae biomass method might be the better route.

Great video Dave. I had to pause the video to go check out Nori. A very interesting company. I drilled down to one certificate (Harborview Farms, which is about 90 minutes northwest of my home) to try to understand more about how the whole solution works. Pretty interesting. Nori, if totally legit and honest/transparent, is an example of capitalism at its best: see a problem (aka opportunity) and figure out how to solve and make money doing it. Nori's approach of connecting consumers (large companies, families, some individual wanting to fly to Europe, etc.) as customers wanting to buy carbon offsets to mitigate their carbon footprint - with Nori will connecting the consumer to sellers (like Harborview Farms w/ no-till farming, winter cover crops, etc.) to fulfill the offset.

Grow these crops using permaculture methods such as using nitrogen fixing plants etc. Reduce meat and dairy consumption freeing huge areas for these processes. Improve efficiencies of currently used systems. For instance gas that can be used for heating can produce electricity at the same time giving micro generator to the grid. The more heating needed the more electricity generated.

Well, it has worked in the past - probably because "the system" is more diverse than we think: With the same "system" as today, weve had numerous environmental problems already until today.

And acting on their suggestions. Governments put regulations on pollutants, the industry came up with technical solutions - and so today your children dont grow up with brain impairments due to leaded gas any more. The ozone layer is recovering - and asbestos doesnt cause lung cancer either any more. Because we substituted it with better materials. The difference of the problem now is in quantity: it is arguably the biggest challenge we have faced in the environmental field (Id say imminent WW3 was a bigger one politically) so far. With the most powerful players in the world for the last century to lose the most: Fossil fuel companies. Ofc they wont give up without a fight - we wouldnt in their shoes. The tobacco industry, orders of magnitude smaller, didnt. It took decades for politicians to act upon the science. And the science to be upheld against the same doubt and misinformation and fraud conspiracies, often instigated by Tobacco industry run marketing campaigns back then, by fossil fuel industries now.
