We're destroying our environment at an alarming rate. But it doesn't need to be this way. Our new channel Planet A explores the shift towards an eco-friendly world - and challenges our ideas about what dealing with climate change means. We look at the big and the small: What we can do and how the system needs to change. Every Friday we'll take a truly global look at how to get us out of this mess.

Do you think we should tamper with nature to stop ice from melting?
Like trying to stop a tsunami, just in slow motion. Don't even try.
Dr. Gilbert herself has said we're looking at major sea level rise within 5-10 years when Thwaites is likely to collapse. I'm not sure why you chose to frame it as an issue for the end of the century.
Climate changes are all Human caused. We already "tampered" with our environment in self-destructive ways and have now become "the" endangered species. Why can't Humans take responsibility for this mess instead of continuing to have more babies and use more petroleum?
@@verafleck I refuse to surrender to Climate catastrophe. I have some grandkids on this Planet, and, I like Humans. Well, most of them. 😊 The WAR Mongers aren't my favorites, obviously.
Sounds like a suicidal idea. added to the fact that this climate is not caosed by us. The mass extinction is(chemical pollution).
I was wondering how the other ecosystems, like fish, will go near cold water if it was blocked by the curtains to prevent them from going in?
They adjust to change to fìt into the cyclical renewal of the Planet.
@@richardlilly2802 ahhh i see
Honestly the idea of the sea curtain is not practical at all and might actually have opposite effects on the climate. The curtain would obstruct sea currents, which cycles the oceans. The ice in the poles act as an enormous refrigerator to cool down these sea currents, and having a curtain blocking that behavior might actually cause more heatwaves.
No one is suggesting blocking of the entirety of the polar ocean. Just the areas where the ice sheets most prone to collapse meet the sea. "Only" a few hundred miles of barriers.
@@Meloncov Thanks for clarification. Though, in my opinion this kind of project needs research time and money to be proven harmless or have low impact on the environment. I would argue that this time and money might actually be better spent in renewable energy making it cheaper and more competitive… I don’t oppose geoengineering in general, but i think the issue needs to be solved at it’s roots and having lower imitations…
@@HosamGemei You mean the plague of humanity? Tackle the course, not the result.
My bet is on the volcanoes deciding everything.
There are 48 volcanoes in Antarctica and only 2 of them are active.
Clearly if you put loads of pressure on top of a volcano (for example by covering the land with ice that is a couple of miles thick), then the land will be pressed down and the lava doesn't move much. So if suddenly there is less weight resting on top of the volcanoes to lava would be more free to move to the surface.
When the lava makes it to the surface an enormous amount of ice will melt, resulting in a sudden increase in the amount of lava moving to the surface, and more ice melting. Also the ice hundreds of miles away from the volcano will be covered in black volcanic ash, so that ice will heat up in the summer sun shine.
Also if you have lava heating water and there is suddenly a river of hot water traveling to the sea then everywhere between the volcano and the sea will experience ice melting.
I think the volcanoes will win.
Agree
@@richardcowley4087 mankind is not in control of the climate, like a driver is not in control when they crash their car.
Mankind is responsible for emitting too much CO2, which is directly changing the climate many thousands of times faster than it naturally changes.
quick, lets think of a hypothetical volcanic disaster, like in films, instead addressing the damage we are causing to our habitat and which is making the production of food in this planet so much more unpredictable.
@@mespabilo yes, good plan
are you suggesting that volcanos produce heat and effect temporary climate change?
i love that society at large will do anything except stopping fossil fuel use. like, we'll wrap a continent of ice with a skirt before being told to eat less meat or keep our AC a bit higher.
Individuals can only do so much when it is the industrial giants that are the main culprits.
It's Climate Adam! Great video, they should Collab more often.

oh hi, Charlie!
@@ClimateAdam Hi Climate Adam!
We love Climate Adam! DW is awesome as well I'm subscribed to both!! Everything in our natural world can be explained with science math and physics.. teach your children well and VOTE.
We'll still be asking this question 10 years from now.
unless of course we start to see a global cooling and then we'll be headed for another ice age, and we'll be forced to admit that climate change has been going on LOOOOONG before humans were here!
More like 100 years. We are constantly trying to find solutions to a problem that doesn't exist
Thank you for spending the time to create and share this content 🙏🏾
You should do it! The project should be funded by the biggest polluters. Because it is simply their mess. And the same goes for many other projects for saving the environment.
No one will give him funds.
@@matildo4ka7 What if they make such law. And it sounds fair if you made billions polluting our world you should pay for it.
Ah, there it is, my daily dose of existential dread.
Going after climate change with renewable resources is geoengineering. We are trying to reverse the current trends of the climate with the solution that is least likely to fail. It is geoengineering. It is not a distraction. It's exactly what we are doing now.
To convince the conspiracy theorists you could have used actual ice and water. The current is a good example for what was described. A timelapse of the actual process happening on a small scale would be a big help in strengthening the claims.
Wouldn't building sunshades in geosychronous orbit be a better idea than an underseas curtain around a continent?
I think yes, but i think there was a documentary somewhere that calculated that we don’t even have the natural resources to build such a thing. Someone please correct me if this is wrong
If you block the sun over a large area, this area will be permanently coolder than before while areas around it will still experience a day/night cycle, so there can be rather dramatic changes in air currents in the souther hemisphere affecting weather far and wide around the world.
Isn’t it possible for battery cars companies to exchange fossil fuel driven cars with battery driven cars from those who own cars? I mean if it is possible, it would be a great solution to overcome global warming.
scariest part is that the oceans still haven't realized the rise of air temperature that already happened. I'm afraid that we won't have to wait the end of the century to see a lot of catastrophic events due to global warming
Oceans don't realize anything. What lies you have heard. Gee they said something would happen but hasn't so the water just doesn't know it yet....durr
Let's embrace inevitable human extinction.
@@kiranraveendran2437 nah, we will survive as a species to look at what we have done
@@kiranraveendran2437 it probably won’t be extinct level event but definitely a huge loss of life all the natural disasters will kill off a good portion and the rest will survive off a mostly non electrical civilization for awhile
Says who ? The scientists who depend on their funding and wealth to promote this. Climate change is a natural phenomenon, it happens. The sun affects significantly what happens on earth. At one time earth was 8C warmer than today and life still existed. Storms occur , they have through all time, lands flooded or swept away , there is nothing man can do to mitigate the consequences irrespective of what they do. Any single event is just weather, unless it suits the scientists demand
I say no to the iceberg curtain!
Say yes to megalake projects to offset the volume of ice melt into freshwater resources. This can be done with desalination.
The sheet would stop the warming of the ice sheets, but will cause overall accelerated warming for the rest of the ocean
Could you please explain that?
@@richardcowley4087 There's enough being said in scientific circles about the interruption of currents and tides which is HOW the ocean cools itself. I think it's a valid statement. 🤷
We could add a reflective or white curtain on top of the water or a white color to the water to keep the water from heating up as much and allow it to be cooler to freeze easier
Ooh, I am intrigued by this.
If we can reduce the parking lots land use by 80% by making parking garages cover them in living vines and have solar on top.
All the new freed up land can have trees flower's and places for people to rest there feet in the cool shade and not the heat.
This will prompt people to walk more and not drive for it will be a nice walk not a burning hot one.
Capitalists cannot accept those suggestions.
Have you ever been to the United States? We need cars to do virtually everything. Every community would have to be destroyed and redesigned. Can't happen.
@@christopherd6399 um I do and it was designed for people walking then we redesigned it for the car.
Also I'm talking about the big parking lots like the ones Walmart has and bigger and these places make billions every year they can afford it.
I don't think we should geo engineer anything on this scale in such critical time restraints when the source of the issue could be terminated. Those in control of fossil fuels being extracted and implemented will use it as an excuse to do more of the same. You can absolutely be sure they'll even invest in these projects as a way to deflect from scrutiny or punitive legislation.
My opinion: Fix it at the source.
just get the attendees of Davos to pay
"Tragedy of Commons"
Dw plantet A needs to talk about Ecosia they are a search engine that plants trees
Cutting our emissions and getting serious about employing techniques to reabsorb CO2 (rather than our governments/scientists talking about them all the time) - is obviously the best thing to do.
Although I don't like the idea of geo-engineering, because of probably unexpected consequences, I think we've left it all too late to avoid needing to use them in the short term.
Carbon dioxide is actually a minor player, but governments like to talk it up. Methane is far more important but we have little control of its production. Ants and Termites produce huge amounts and it come naturally from the breakdown of organic matter. Water vapour is actually the most important gas but who wants to get rid of it? Clouds and emissions from politicians mouths?
From what I’ve seen, carbon capture is a pipe dream. Think about how easy it is to burn gasoline vs gathering the dispersed CO2 and returning it chemically into a non gaseous form. By law of thermodynamics, it is so unfeasible to bring carbon capture up to the scale that we burn fossil fuel since it requires more energy to capture than to burn in the first place. Where’s that energy going to come from?!! This is all to say we absolutely must put our strongest efforts into reducing burning fossil fuels first, and not let fossil fuel companies make you think we can just “offset” carbon emissions through carbon capture. Cuz I’ll tell you now, there’s nowhere near the amount of carbon capture happening to offset fossil fuel burning
I’m not trying to be argumentative or anything. I’m just saying I don’t see viability in carbon capture as a solution to reducing atmospheric carbon
@@chadmackie3438 true but at this point I think every little bit will help, although, the resources/funding spent developing carbon capture technology could arguably be used in far better ways to help reign in global Co2 levels.
Why do you want to get rid of co2?? its the gas of life and without it there would be no life on earth . Its a nutrient NOT a pollutant and all life on earth benefits from more of it go do some proper research and I dont mean the IPCC try independent scientists like Dr Robert Holmes, Roy Spencer, Patrick Moore etc
Well done Adam, was a surprise hearing your voice on a DW video
thanks for watching!
"not likely to happen" is language we shouldnt use. because we will continue to go on as usual because we dont feel threatened, and then it becomes more of a certaincy.
Maybe a cheaper, easier solution might be to fertilize plankton, alga, and so on in the World's oceans? There are a couple of clips on RUclips about this. I've heard about some fairly inexpensive experiments done in the Antarctic Ocean, where there was iron oxide (rust) applied during its summer, and ka-ching a few days later an alga bloom. A decade or two back, so it works, I guess. Which was snaffled right up by some passing whales.
It's not going to stop ice from melting in Greenland. You cannot choose 'one size feets all' solution for complex natural problems.
You are talking about intentionally creating algae blooms in the middle of the oceans at such a massive scale that it changes the global climate, a technique with the potential to disrupt ecosystems in ways we don't currently understand and create a lot of damage. It should be a last resort if we ever attempt it.
We have to choose between environment and industrialization. Only balance is guarantee of our existence.
aren't the polar caps heating up faster than the rest of the world? putting a curtain would just trap that heat or divert it towards other glaciers, no? seems very short sighted to me.
Since the formation of the earth, the poles have mostly been ice-free. Ice ages are exceptions, the warm periods make up 80 to 90% of the earth's history. In this "normal state" the average temperature of the earth is 20 to 25 °C.
@@uwedallinger4887 so I guess our climate is just changing back to its "normal state" and we shouldn't even be talking about under water curtains and melting glaciers.
Ambient night temperatures are a great example of the heating and heat energy amplification of atmospheric rivers, like we just seen with floods around the world.
The meteorite is 10 seconds away from hitting the earth.
DW: Can we stop the meteorite from hitting the earth?
Stay on topic, but Dr Neil D Tyson on RUclips answers your question.
According to tide gauges, sea levels are not rising any more than they were 100 years ago. Why isn’t that fact mentioned?
Vary good point. Thank you
Sea level rise is the least of our worries. Take a look at crop failures happening all around the world
Responding to the title..i think it is impossible.We just need to adapt.
Increasingly worse events than were predicted in the worse case scenarios. Sooner and more dire.
Not just melting of ice sheets but extraction of ground water as well will increase sea level. We are pumping ground water at huge levels
1- Build more nuclear (micro, modular, and breeder reactors).
2- Switch from fossil fuels.
3- Prepare at-risk coastal nations for trouble.
4- Plan for ocean temperature and current changes.
As a species, we'll get through this... but we need modern, small scale nuclear now. Sadly, I think that requires a die-off of the soviet-era generation who stand in the way due to obsolete fears.
We should look for other planets to populate and foul up. Long live our shareholders!
The extra carbon in atmosfere is the missing trees. Plant trees they retain carbon to grow on their wood.
I think it would help if they stopped running almost ice breakers through the Arctic Ice chipping it off and having it float into more temperate Waters of course that's too late now that's already done
This!!!! It's such a simple step that could have real benefits.
could you spray saw dust at the faces of the ice caps in autumn to create pykrete barrier on the ice cap's surface? also, will not the desalination of the southern ocean make ice more likely to form?
We could build mirrors in space to block the sun to these regions.
How much carbon and energy does this require and leave in the atmosphere on earth? The simplest truth is usually the correct answer.
Wouldn't it honestly make more sense to just capture these chunks of ice and tow them to the nearest port cities? Like LA or NYC?
All it is is solidified fresh water.
funny idea but nothing more... considering the price per km and the devastating effect on the local ecosystem
Yes, make it colder.
Really great seeing you do this, Adam! 🙂
thanks Anant!
What if we eat all the ice?
Then it will not be there to melt.
Right?
So what happens when the first iceberg meets the curtain? I’m not sure this has been thought through properly
Putting the ground water back into soil is a good solution i think.
They are way past over depleting the aquifers in Germany and other countries around the world, poop will hit the fans soon as it's only getting hotter.
Sadly no we can't we can only watch as the planet warms up then cools as it's done through out is life.
Most if not all ice will melt with or without our help.
Just back to inside of refrigrator or Freezer... hahahaha
Human intervention even those with best of intentions can end up being opposite. Case in point is Plastic. Some one thought plastic would be great to save all the natural resources and since then plastic has been worst for nature. The idea behind EV was to save fossil fuels but way US industry is mass producing high torque cars that need huge LIon pack for Instant juice is turning each electric car production 3 times more dirty. What people need to learn is moderation. Small fuel efficient cars, less consumerism , less wastage
I have a question: why don't we pipeline Greenland's ice melt inland to keep freshwater from going in the salt water? Inland's all been in drought now with our heated world. We desperately need more freshwater.
We can always tow icebergs for fresh water
Let's discuss the fishing catastrophe, too?
Has anyone ever calculated land reclaim done world wide. Places where there was sea once now we see houses, airports, container terminal and parks. Its like puting bricks upon bricks in a swimming a pool and than complaining rise in water level. Just calculate the total area of sea water displacement due to land reclaim and than see how that relates to sea level increase.
What if we find a way to remove salt from see water and makevit usable in drought struck regions. Plus we can put the brine back to rhe ocean since climate is also dependant on level of salt in the sea water. The only downside is the enourmous energy required to do it
I do not agree with such way of tampering with the nature
It could lead to every worse outcome due to underestimated consequences from project of such proportions and type
If you look at the historical temperature of the Earth you would see we are in a cold spell now. It is supposed to get warmer. It has been getting warmer for a long time before human intervention.. As the folk who used to live on Doggerland or those who happily crossed the Bering land bridge. We picked a bad time to develop our civilization on the coastlines. Sea level will continue to rise. As Ice melts it speeds up due to the Albedo of its surface. Do not try to mess with this force. We know not the consequences.
its not supposed to get as warm as we have already made it. If we are in a cold spell, this cold spell is 1-2degrees higher than it should be... we are currently seeing the efffects with extreme weather happening more frequently.
I would reccommend to watch Simon Clark's RUclips video called "Was England really warmer in medievel times" in which he shows the historical global tempurature graphs which shows the Average Tempurate increase in accordance to current science.
the Earth is getting warmer and its due to us, humans, pumping too many greenhouse gases into the atmosphere which needs to change now, as rightly you said "We know not the consequences."
Here’s a novel way to stop 🛑 ice 🧊 sheets collapsing and melting into the ocean 🌊-just add lots and lots of CW7 to the upper layers of the atmosphere and cool down the globe 🌎 by about 50C. That’ll give sea 🌊 level rise one blaze 🔥 of a beating.
The big companies causing the raising temperatures are well known. That is 99% of all problem.
Let imagine where I'm living far away from the beach 3 hours to drive or 120km, one day my grand child can see the beach from our house, so I don't have to move to the beach anymore
So.... Glaciers are pushed downhill by the weight of the ice that builds up on land. Not one climate scientist ever mentions the surface mass balance of the ice sheets, this would include ice lost in the sea AND the amount of ice that accumulates inland from the copious amounts of winter snow.
You plug up one the ice will find another wayback. There are not enough oysters
Sorry, but this video is a vast understatement of the severity of the situation.
Wouldnt it be possible to produce our own ice ? Like coudnt we have maschines places in the arktis which suck up the water and produce enormes ice cubes or ice plates ?
Produce billions and billions tonnes of ice would require enormous amounts of energy.
And the machines... Wow! I can't even Imagine...
Do you mean snow?
Can we please commit to Modern advanced nuclear energy options. It will give us a stable electrical grid where we can also connect renewable alternative energy options to it. Where right now, we run alternative energy from a grid that's based on fossil fuels.. c'mon, our tech, knowledge, and understanding of safety and material science/engineering/chemistry has advanced so far that we can move past our PAST. We can heal from our trauma. There's a lot of positive waiting to be potentially utilized. We just need to give it a shot. Anything is better than what we currently are experiencing.

Hey climate Adam, good to hear you out in the wild ;)
who? me?!
I think we need solutions like this to buy time. If we think that there is one practical solution that isn’t messy in some way we are wrong. Curbing emissions is essential and the most beneficial. That said even if we do completely do so there are still problems because we waited so long. Solutions like this while messy are imperative to buying time. The worry is that people will not change after they are implemented which I think needs to be addressed. I think people just resigning to us being doomed is only hurting these causes too, much in the same way climate change denial hurts society
What we need to is slow the earths rotation, this will reduce friction and we all know friction makes heat. Only if we slow it too much, there will be another ice age.
Dithering until it's too late and then improvising solutions is what we humans will do regarding climate change. Massive population displacement will likely cause conflict. Maybe those who survive will have access to technological advances in a less populated war-weary world. Might be a sort of golden age. We'll see.
You know i had read that 87% of earth whole history, it didn’t have ice capes. So I guess the mear fact that human are here now and it seems we just are trying to keep it the same rather then changing naturally. Don’t get me wrong are carbon output is definitely one main issue among many. Just an interesting look.
Another question I have is how much is adding to sea rise though I feel it would be low but still a small factor. Land reclaiming in the oceans and pumping water from aquifers underground adding to ocean lvls
You know i had read that 80% of earth whole history, oxygen levels were lower than 5% and there were no animals or plants. So it would be perfectly natural and irrelevant if we killed everything.

That's a very expensive and carbon releasing band aid that slows it down a very small amount for a short amount of time.
Seriously, is this what smart people come up with?
Have we crossed the point of no return in terms of damaging the planet? There is no such point. We need to trust that our thought, which is our greatest quality, can change nature. We only need to understand the direction to which we should aim our thoughts. What should we think about? What condition or state should we aspire to and ask for?
In order to save our planet, we should think about positive human connections. That is, how can we, in our connections, keep nature safe? How can we all together protect our world? If we truly wish to better our planet, then we should see people holding a concern for how to positively connect everywhere that we look.
It has nothing to do with recycling or other activities that we commonly associate with as being sustainable. If we come closer to and consider each other, that we will reach an entirely organic, perfectly connected and round state, then the negative forces will disappear from the world.
We need to understand that if we start thinking better about each other, then the planet will recover from all harm, because our thoughts are the strongest force in nature. Likewise, our negative thoughts about each other are entirely to blame for damaging the planet. That is why the more we recycle and invest in energies and activities that we commonly think of as being sustainable, the worse our planet becomes. Nothing will work to benefit us until we reach a state where our attitude changes toward each other for the better to protect and improve our planet.

What about liquid nitrogen, release it under the base of the ice sheet where the melt is reducing contact with the seabed, is warming up the area and increasing the rate of ice melt.
It is the same with Hurricane, if they require certain temperatures to maintain the storm release liquid nitrogen in the path/at the front of a Hurricane to stop it in it's tracks or reduce its severity. Money for jam for insurance companies I would of thought, spend $100000 on liquid nitrogen application and save millions in insurance claims.
Will the curtain block the ocean current or interrupt marine animals? 🤔
Lots of saw dust.
Can we stop ice sheets from melting? No. Next question.
Funnily enough, I’m in full support of geoengineering activities like this because I was convinced by a video by Climate Adam (who’s narrating this video).
In his other video, he talks about the insane cost to try to geoengineer another planet like mars vs applying that same money on earth. The result is that you get way more bang for your buck when you dedicate that money to earth geoengineering. I’ll edit in a minute with the title of his other video.
Edit: it’s called “Mars won’t save us from Climate Change”
P.S. The scientist Ella Gilbert here has her own channel called Dr Gilbz. Really great if you want to hear more about these specific ice sheet issues.

Short answer 😌 no
Before the life ending event, that caused the glacier's, animals were found in the Arctic frozen Standing upright with mouths of sub tropical foliage
tectonic plates shift so the evidence for that kinda life doesn't really mean it was happening at the poles. Antarctica was part of part of the last super continent and has drifted downwards since. From what I understand it's land was once in a position similar to today's Australia. I'd like to see what you're saying on this if you could source me.
