This is hands down the best science channel.
I whole heartily agree.
"this is hands down", I will look out for it, in the meantime, I will continue watching Anton..
Yup. I rarely miss a day.
It really is, you can barley find such well researched and hot off the press deep science news on youtube.
Anton has just the right amount of "Quirky" and as the stereotypical scientist is "Mad" Anton creates a character on the "Borderline" of "Quirky" .Apologies for the "Over" use of quotation marks.
When you nerd out on hard sciences...you nerd out on them all: from astronomy to geology, to biochem, to metreology
This guy’s good…REALLY good. It doesn’t matter the subject area he dives into!
It's not dimetal sulfide.
It's dimethyl sulfide.
particle physics 👍🏻
So very true🎯
@@frinoffrobis yeahhhhh definitely 💯
- Saw the title of this new video about 5h ago.
- Did not watch the video because I was wondering what DMS is and wanted to research it on my own for a bit.
- Found myself now, 5h later, having written a bunch of notes about everything from marine biology to climate gases to agriculture and livestock regulations to animal rights.
- Finally feeling ready to watch the video.
What you mean by livestock regulations?
@@r.guerreiro140 I meant laws and practices on animal husbandry, specifically in this case the classification of different types of egg production (biological, free-range husbandry, floor husbandry,…) and the tethering of cows.
Sorry if “lifestock regulations” was a bad translation, english is not my first language. German is.
One question, why. This video was probably enough. Anton is really good at giving introductions.
@@Just-a-Orion-on-the-internet. True, but sometimes I just get a itch for things.
Respectable
Anton is a master of sci comm. Somehow these videos are incredibly densely packed with well-crafted information, yet delivered at a pace that is easy to digest. Other youtubers would do well to carefully study Anton's work.
Your final take of Dimetehnelnopenenne was excellent!
Thank you, Anton! This episode completely blew me away. I was aware of some of the common facts about DMS and, oddly enough, just last week I had made a comment to a friend about what actually produces the smell from bodies of water. After seeing this video, it's become clear to me that amongst the complexity of our ecosystem the Earth is fighting back. Simply Incredible.
I think life as we know it is incredibly rare in the Universe-so many things that had to come together in a perfect way. Which makes me feel like the winner in a lottery with incredibly low odds. Sobering thought! We should cherish what we have on this pale blue dot-it was not give to us to destroy. Rather, it might be the best thing that ever happened, in the history of the universe.
Even if that is the case, the sheer amount of planets and moons out there mean there would still be millions to billions of places to replicate life as we know it
This is also my take. I joke that when the big bang happened the particle that would one day become the basis of the Earth yelled "BINGO" and we won the life lottery.
@@joelhungerford8388Do you have any evidence to back up this claim?
A wonderful video to finish the work week.
Thank you, Anton.
As I understand. High clouds reflect before absorption so cool. Low clouds absorb, insulate, and so warm.
I am thinking that DMS could wind up being just another greenhouse gas like methane or carbon dioxide. We don’t just need clouds to cool the planet. We need high clouds that reflect sunlight. I am inclined to think that DMS could wind up making thick, low clouds that produce lots of rain and holding in the heat, making Earth a hot house planet.
yes, now u tell me who is making an unprecedented amount of low clouds ;)
@@ili_711 Only commented on thermal physics of clouds. Ask a meteorologist.
About the CLAW hypothesis, I'm sure there's some of that happenning, as well as _other_ negative feedback processes that work to bring global temperatures down. The *big-ass-elephant-in-the-room* real problem is that, _in the balance_ , the sum of positive feedback loops outweight the sum of negative ones (with the ice-albedo and methane-thawing ones the main players). And this unbalance is probably only going to get worse, so I wouldn't be getting people's hopes up that "she'll be right"...
The main player is the SUN look at the distant past. Climate changes-we just happen to be in an inter-glacial period.
DMSP is a photo-protective compound which many ocean plankton species use. DMS is its derivative released after those organisms die. That is something we learned over the last 30 years since the CLAW hypothesis (discussed in the video) has been formulated.. The new paper adds to the lists of organisms which produce it but does not increase its flux into the atmosphere because it is measured independently. So nothing has really changed.
Wouldn't the increase in algal blooms around the world result in more dead algae, which would raise the amount being released into the atmosphere?
@@Canthus13 Yes, if the increase is real. I've seen papers claiming a decreasing trend in phytoplankton biomass but I know they are controversial. I have not seen those claiming a positive trend, yet. So it is hard for me to say how robust the result is.
PS. It seems the increase in marine primary production in the last 3 years to 2023 is a partial reversion of a longer decreasing trend. So it may be just temporary.
@@Canthus13some biomass from blooms sinks and is trapped in the sea bed. So I guess it is complex.
@@arctic_haze I don't know about those papers, but I do know we've had several blooms in Lake Erie in the last 20 years, a couple of which made the water undrinkable for days. Seems to me like we need to fix our shit before nature decides to do it. Nature might kill us in the process.
All lies, get ‘em out of here.
Excellent explanation of extremely difficult material 👍🏻👍🏻👍🏻
Many thanks Anton
I knew nothing about this. I'm gonna find out more now.
I think this video is a good illustration of how science can be very interdisciplinary. Thanks!
After eating beans I've been known to create a "stinky gas," myself. Never heard it called "DMS," however. I didn't realize I could be cooling the Earth.
Can you believe that Anton puts out videos like this every single day?
Potentially good news. I always wondered how Earth recovered from its past thermal maximums, and this could be the answer. Really exciting stuff.
ROFL... how did you get away without the TH-cam 'tramp stamp' for environmental videos?? Glad to see someone taking a real, unbiased, hard science look at this. Thank you !!
Interesting video today, the suggestion that the production and release of DMS, DMSO and related sulphur compounds in the ocean could account for localised surface water temperature rises is intriguing, especially considering their typical role in atmospheric cooling.
There are a few mechanisms that are worth investigating further to see how these mechanisms may provide an insight to take knowledge forward.
1. Heat Release During Metabolic Processes
The production of DMS and DMSO by marine organisms involves metabolic processes that can release heat. If a large number of organisms are producing these compounds simultaneously, the cumulative heat release could raise the temperature of the surrounding water. This effect would be more pronounced in localised areas with high concentrations of DMS/DMSO-producing organisms.
2. Impact on Light Absorption
Sulphur compounds and their precursors can affect the optical properties of seawater. If these compounds alter the absorption characteristics of the water, they could potentially increase the absorption of sunlight, leading to localised warming. This might occur through changes in water clarity or the optical properties of dissolved organic matter.
3. Algal Blooms and Heat Absorption
Algal blooms, which are often associated with increased DMS production, can significantly alter the thermal properties of surface waters. Dense blooms can increase the absorption of solar radiation due to the pigmentation of the algae, leading to localised warming of the surface water. This could create a feedback loop where warming enhances algal growth, further increasing DMS production.
4. Physical Processes and Stratification
The production of DMS and related compounds might influence water stratification. Increased production of these compounds could be associated with biological activity that affects water density and stratification. Enhanced stratification can reduce mixing with cooler, deeper waters, leading to localised warming of the surface layer.
5. Biological and Chemical Feedbacks
The interactions between DMS, DMSO, and other sulphur compounds with marine microbial communities can create complex feedback loops. For instance, certain microbial processes involved in sulphur cycling might produce heat or change the thermal properties of the water, contributing to localised warming.
6. Interference with Evaporative Cooling
High concentrations of DMS and other sulfur compounds might influence the rate of evaporation. If these compounds affect the surface tension or other properties of the water, they could potentially reduce evaporative cooling, leading to a slight increase in surface temperature.
7. Release of Greenhouse Gases
Although DMS and related compounds typically contribute to cooling when they reach the atmosphere, their production and release might be linked to other processes that release greenhouse gases such as methane or CO₂. These gases can trap heat and contribute to localised warming. This is a more indirect pathway but could be a contributing factor.
Understanding these mechanisms requires further research, particularly focusing on the localised interactions between biological, chemical, and physical processes in marine environments. It's a complex system where multiple factors interact, and isolating the exact cause of localised temperature rises associated with sulfur compound production will necessitate detailed field studies and advanced modeling efforts.
I'm not really surprised. I've long suspected the climate system to be permeated with many more feedback mechanisms (both "positive" - i.e. amplifying - and "negative"/"dampening") than we've ever thought existed.
That's not to say the climate system is somehow magically hyperstable and immune to anthropogenic destabilization, but given the focus of climate scientists on identifying climate challenges humanity can actually do something to address, it would not really be surprising if natural dampening feedback mechanisms like those highlighted here ended up being less well understood or researched.
A bigger problem with SRM spray is the aluminum dissolved in the sulfuric acid. It inhibits root growth and makes it easier for trees to ignite. It also can cause headaches and challenges the imuno system.
Thanks for what you do fella! Always worth the watch!
Man, I love this channel so much. We appreciate all you do. Truly
Sorry for the amount of DMS I produce. I blame my diet.
Life shapes it's environment.
And vice versa
Environment is the backbone of life. Yes life has a certain degree of influence on it but many things stay abiotic factors. Certain global warming events caused by volcanoes or even interstellar events may have had major influence( could be factored as a harmful influence) on life itself.
@@Just-a-Orion-on-the-internet. There is life to be found from the edge of space to miles down into earths crust. Life changed the composition of our atmosphere, the oceans, fossils grew into mountains and life even created the fertile soil in your flower pot. Without life, earth would look like mars or venus. Life shapes it's evironment, creates more and more nieches and ecosystems. It needs something of cosmic proportions like a stellar collision or star going red giant to sterilize an entire planet, leaving zero chance for life to make a comeback.
Love the optimism and insight! I’m afraid that the rapid development of desalination plants around the world stress the Earth’s homeostasis. The brine waste byproduct of desalination plants causes shifts in pH of ocean water (ocean acidification) that not only triggers deglaciation but also “cooks” delicate marine life ecosystems such as coral reefs and plant life. Unless immediate measures of diverting brine byproduct (such as brine evaporation to make potash - a powerful fertilizer) or ramping-up alternative, eco-friendly, methods of desalination … then a catastrophic geo-global collapse of Life is not far off in the distance of time.
Cheers, Anton 🤠🖖✨️
Wonderful as always Anton. Thank you. 👍😉☺️
Fascinating!
You Are Sooooooo Special ❤
TH-cam cares? Don't delude yourself. You keep making great content they'll keep on cashing in!
Anyone else get tired of looking for the 41 seconds (at best) of useful information per every 15 minutes of video?
I'd go to sleep to this but the anger keeps me awake.
The more we know, the more questions we discover.
Hi Anton, this is one your best videos, because of the way you connect different fields and theories.
Hi wonderful Anton! 😊❤🎉
Great as usual Anton mate,keep doing what you are doing.
Well, yes - let's hope these guys don't over-fart, and don't throw us in another ass-chill 🥶🥶
Anton my good man, you sir are truly the best! My hat is off to you sir!!
Top level presentation and a glimpse of the efforts you put in that we do not see, you are a great man, thanks
DMS turn into, undergoes oxidation turning it into sulfuric acid.
So, it may promote cloud formation, but when it rains it will be acid rain, amai.
Thank you Anton, these are top notch videos for astronomy 👍💪 hello wonderful person, always gets me, you have a good personality
Haven't missed one of Anton's videos in years now. Always something to look forward to and overwhelmingly more usually than not, something new to learn.
Have to say, the "fingers crossed" comment about the CLAW hypothesis didn't strike me as a ln unduly viable strategy to mitigate climate change .... but if that's all we're left with when the robber barons are done ..... !!
Thank you Anton for spreading wonder!
The more we know, the better our chances of managing and reversing global warming.
Thanks, Anton!
While it is good to know that algae may help to cool the planet and theoretically more algae is a good thing, algae blooms can totally decimate ocean ecosystems by depleting oxygen to the point where native plants and animals all die. There are many of these places and some of them are huge like the one in the Gulf of Mexico caused by the run-off of farm waste, (manure, chemicals such as phosphates and others that algae just love). It can encompass 10,000 sq miles and anything that swims into it dies including fish and most recently dolphins and other higher-food chain animals all of which basically suffocate since the algae have used all the oxygen. Every loop has feedback somewhere so we should be careful when messing with planetary systems.
I love your work. Thank you,Sir.😊❤
The assumption that more cloud cover causes cooling through reflecting heat from the sun is very dangerous. It potentially has a worsening effect on human induced heating, reducing heat loss into space.
We've been seeing these algae blooms near the southern coast of Lake Erie.
I thought it stank too, turned out neighbor composting poop
@@CanadianStargazerThe pig factories have lagoon overflow and also spread it on the ground just before rainfall.
@@carmenmccauley585 looks like those factories/farms taking advantage of loopholes in the bylaws.
Very interesting video, thank you for the thorough explanation! Really appreciate how you break down these concepts, it’s really relaxing and interesting to listen to your channel as I work!
Thank you, Anton, for a maybe-just-maybe I can maybe feel good about! 😊❤🙏🌎🤞
Yeah, that was quite interesting. Important knowledge.
Thank you for the fine posts
I agree
Thanks again for digesting this information for us.
Enjoyed this video and learned a lot.
Geoengineering by aerosols is really making more complex and costly ways to live in a biosphere damaged by our already evident geoengineering, namely adding CO2 to the atmosphere. It's like having one foot on the accelerator and the other foot on the brake. Surely it would be easier and cheaper for humans to stop their already accidentally effective geoengineering.
You'd think, right? But then that might affect the profits of the wealthiest individuals on the planet, and if we did that they might ruin the economy and destroy our standard of living.......oh, wait... 🤨
Solar Radiation Management is probably the least bad option at the moment, among the options that are realistically achievable.
Thanks Anton, super informative as always. Grtz from the Netherlands 🇳🇱
Een Nederlander gevonden!
Great video as usual Anton.
Love the blooper.
Exciting, very interesting content,thanks👍🤗
Fun fact: we can create our own DMS by making paper (it is a byproduct of the kraft process)
Hello wonderful Anton!
Thank you Anton
Don't make the mistake that this means we don't have to make some major changes in the energy sector.
Anton video with morning coffee? Love it...
Edit... In before TH-cam puts a context memo... 😂😂😂
Same here ☕
1:39 Priceless fam!
In systems theory this kind of regulatory effect is referred to as an emergent property and a form of homeostasis. Such mechanisms must exist in the regulation of climate for Earth's current climate to remain within the boundaries it has for as long as it has. For dramatic effect doomsday theories generally replace systems effects with straight line progression s that go careening off to catastrophic ends.
Homeostasis works until it doesn't. Then it really doesn't.
As a doomsayer, you would call me. What you say about the 'Regulatory effect' on our climate is well documented .
It is not though the Biomas/Biodiversity on earth that is causing climate change(Us aside of coarse) it is the longer term planetary momentum that is changing despite it.
The "Age of ice" by which I do not meen an Ice Age I meen the the era of there being any ice at all oat the Poles is a resent one caused by the closing of Central America and the effect of that on Oceanic Currents.
Ignoring "Snow Ball Earth" if I may on the grounds that ,That was a verry different planet subject to different staring conditions. not least no /Verry little, life, the natural condition of Earth is warmer than we have been lucky enough to have evolved in: add to that the locked in (Permafrost)green house gasses at both poles and I can only say I hope you never get the Kinde of "Dramatic Effect" it seems you would need to be convinced.
@@johnh539 I can happily predict the climate extinction of the human race in less than a million years, not by 2050 as might be feared. Let's not confuse geological history with human history. Today we are closer to a nuclear war mass extinction event than at any time in human history and frankly the prospect that climate change will be our demise falls far short of arrogant stupidity of our ruling elites. Just a thought 🤔
If this crap is what you tell yourself to sleep at night, great, you hang in there buddy.
But it is actually BS.
_"...Earth's current climate to remain within the boundaries it has for as long as it has"_ ??That's the whole point, that's the bit you don't want to look at. IT IS changing, we have _decades_ of data (plus centuries, millenia, of indirect data) to prove it, and those trends fit perfectly with antropogenic hypothesis that we've also had for a very long time.
But you go back under that blanket and don't worry, nobody is going to take your SUV(s), your steaks, away from you... 👶🏼
DMS is formed in the production of beer also. So my takeaway is that when I drink beer I'm helping save the planet. I'm a freakin' hero :D
Loved the show. I'm a chemistry buff and this DMS chemistry is new to me. I'm pretty good at pronunciation if you need help. That shark smile of yours is always my favorite part of the show.
How about doing a biography about yourself? You have a lot of subscribers and building rapport is going to make you stickier. And tell people at the beginning of the show to go hit the thumbs up button and that you promise the show will be worth it. 😁 You're a star.
Nice one Anton!
OK, so DMS produces more atmospheric sulfur, which creates more cloud cover but then doesn't that cause more acid (H2SO4) rain which kills plants?
This was also my concern. Sulfur in the atmosphere may combine with water to form acid rain, which we worried about in the past. Doesn’t this put the forests and lakes at risk?
Interestingly, cloud cover has decreased from about 64% to 62% from 1982 to 2019. These data are from CM SAF, Satellite Application Facility on Climate Monitoring.
The Hopi Indians, believe if the earth warms, expect snow, this could prove them right
The chemist here: DMS is not just stinky but extremely odorous and smells like fermenting dead rats. It's smell can cause immediate vomiting. 😉😂
So very very stinky
dmso is a solvent that goes through the phosolipid-bilayer of cells with great ease
looks like the same key
throw it in the kitchen junk drawer with the others we forgot
It will be interesting to see the charts that depict a timeline for these micro organisms to be successful at the proposed role.
How about that, looking into the sulfur cycle here on earth and it's impact on our warming planet by observing another planet light years away.
The sulfuric acid part is bit of a concern with chances of decreased ph in rain water.
I already said this on Dr. Becky's channel and I feel compelled to say it here too: My favorite TH-camrs that discuss Space and/or science are Dr. Becky Scott Manley and Anton Petrov.
Life evolving feedback mechanisms to regulate the climate to be more favorable to the organisms seems to be quite reasonable - even likely.
Evolution is an amazing thing. The scale of life from microscopic to planetary. Very cool.
YT, never fails to disappoint. I was looking forward to the side note.
Love the bloopers! ❤😂
Oh we could release all of this into the atmosphere and it would be very good
Won't this also lead to a huge increase in acid rain and thus we SHOULDN'T depend on it to save us from our unsustainable industrial practices?
At last my secret is out. I can finaly let go of the shame.
8:16 3 legged dog molecule? At least in the "tinker toy" type models it resembles humanity's best friend (and worst enemy) the ethanol(alcohol as in liquor) molecule which can be made to look like a dog, but with all four legs.
at the very least this seems like 1 of the (probably many)systems that the earth needs to recover from extinction events, even if we cant use this process to stop ourselves from going out, the earth will recover, and someone else down the time-line, can try to figure out this whole civilization thing.
My favorite are the deep space photos with the mass amount of galaxies everywhere far too many to count. All beautiful and unique. Sometimes I wish I had an astronomer next to me coz sometimes u see weird shapes and blobs and points of light and stuff and I wanna just point to everything and be like "what's that thing!" Lol I looove the bright blue spiral galaxies they are just so freaking beautiful it's just so mind boggling to think of all the galaxies and think of our galaxy and just all the life that must be out there. And I dont mean microbial life but sentient intelligent life. Theres gotta be so much...were just separated by space and time and our ignorance of understanding such things.
If u met an alien billions of years more developed than humans...and u could ask them 1 question...what would it be?
No one does it better, Anton.
Potentially good news ,fingers crossed.
I don't understand how if the cloud cover has increased over the last 20 years the worlds 'Albido' can have been decreasing over the same period as you reported not long ago?
Was I watching an old video sighting old data or are the two things actually happening simultaneously?
You should also note that DMS can also contribute to the depletion of stratospheric ozone, which protects life on Earth from harmful ultraviolet radiation. However, the impact of DMS on ozone depletion is relatively small compared to other factors like chlorofluorocarbons (CFCs).
Overall, the impact of DMS on the atmosphere is complex and involves a delicate balance of factors. While it can contribute to cloud formation and climate regulation, it can also have negative effects on ozone levels.
It absorbs some UV, meaning that there is less UV available to make ozone. Overall the UV is absorbed, so does it really matter if it is the DMS absorbing it, or the ozone that is?
Has everyone forgotten about Acid Rain?
Thank you.
love his brain 😊
Hello wonderful person 😊
if stinky gas is a sign of life consider me the life of the party
i think it's truly the best video i've ever seen, you make it better every time👆👆
And so how different is this result from the effects of "acid rain" produced by pollutants released by certain industries?
I wonder if we could be a stand in for Checkov in the next JJ Abrams Star Trek as a stand in for Anton Yelchin after his tragic death a few years back.. after all, You do have the same first name! And you do look a bit alike. And you appear to be pretty much a real scientist. (yea yea, so you teach high school students..thats one advanced high school! I'm Jelous!) I don't think they'll make you dye your hair blond though your wife might like it! And yea, I'm one of your fan boys. I think I've been subscriber for at number of years! Having someone like you as my science teacher back in the 1970's would have been SO AWESOME!
Thanks!
🎶 we are algae and our cells are filled 🎶 with a green chemical known as chlorophyll 🎶
The exhaust from big cargo ships and the effect on the atmosphere, I find very interesting. If we wanted to put anything into the atmosphere tainting the fuel of those ships would be the best way imo. History has shown aomost every time we try to bionengineer it backfires horribly in our face.. be it pest control or accidental introduction of invasive species or pathogens to areas with no natural defenses.. i dont think we wre advanced enough just yet to bio engineer say an algae to do something different and have it work without negative side effects.. IMHO
I love you
Perhaps using this new knowledge we can create an ocean fertilization strategy that focuses on organisms that produce DMS, have carbonate shells and either sink to the deep ocean or are eaten by creatures that end up carrying carbon downwards and out of the atmosphere for a long time
