- Scientists look to geoengineering and other methods to cool the planet.
Official Website: to.pbs.org/3lWpliq | #novapbs
As global temperatures continue to rise, scientists are wondering if we need solutions that go beyond reducing emissions. From sucking carbon straight out of the air, to geoengineering our atmosphere to physically block out sunlight, to planting more than a trillion trees, the options may seem futuristic or tough to implement. But as time runs out on conventional solutions to climate change, scientists are asking the hard questions: Can new, sometimes controversial, solutions really work? And at what cost?

Trees are way ahead of all the sophisticated stuff that we created to solve this problem. I’m obsessed with nature.
Yes!
You are spot on. This liberal narrative just makes my skin crawl. These ppl want to choke out the plantlife on this earth. The very thing that needs and will regulate the CO2 they will kill killing mankind. Western society will implode and all the rest of the countries that watched it happen will laugh and take us over. Russia, China and many many countries are not on this sky is falling bs. They will be the survivors not the west that are stifling the farmers, killing their animals, don't fertilize the crops, eat bugs, meat is evil. Getting Conservatives back in for 20 years can't reverse the damage liberals have done
The problem is trees are not built and patented by companies, but these machineries are
I'm sorry sir or person the ONLY way to fix this is to STOP this insane notion that we must save capitalism free market system at all cost will cost us the planet you simply cannot have continued growth & consumerism on a planet with finite natural resources and anyone who tells you we can fix this with spraying acid or sulfur in the atmosphere is 100% telling you pure falsehoods we have monkey fucked this planet to death in the geologic blink of an eye . Bravo well played congratulations to the Robber Barons & the titans of industry while you certainly amassed great family fortunes you did so at great cost to the overall planet bravo sir maybe you can eat your money when we can no longer grow food....
Exactly what I was thinking about. All the areas that have been deforestated must be replanted with new trees (especially the Amazon forest). Cities will also need trees in their streets and lots of parks to make up for the space taken by cities (look at Mexico city for example)
I find it insane how no one talks about the magnitude of the rain forests throughout the world that corporations cut down. Those trees removed the CO2 and cooled the planet. When I was a kid this was a huge concern. Now in today's world the corporations have deflected the fault to each individual on this planet. Each tree that was cut down prevented how much CO2 from being removed from the atmosphere? How many trees did it take to change the natural weather patterns that kept us cool? The corporations need to restore what they destroyed before pointing the finger at me. As a consumer I purchase what corporations provide for me to purchase. The bottom line is they need to start at the corporate level before handing me the problem. Until that happens nothing will change.
Some problems
Plastics
Trees
Bi product waste
Factory emissions
Corporation CO2 footprint first!
All we have to do is plant more trees!
Deforestation is caused by eating animals. We're responsible for climate change, we can stop it.
100 years ago there were 6 trillion trees on the planet, today there are 3 trillion. One trillion trees consumes 200 gigatons of carbon. Planting trees might not be the only solution, but we should absolutely be replanting some of those trillions or trees we’ve removed.
@@brianshorey Planting other carbon eaters is good too. Some kinds of hay eat more CO2 than it gives off when burned. Rainforests are possible on small scales over 10 years as one guy has done.
Ten percent of the Amazonas max is lost to feed the planet's population. Overall, the woodlands of Earth have grown by 70% compared to the woodlands of 16-17 hundred. The Earth is getting greener. We have been using coal, oil, and gas, lately nuclear instead of as before, wood and dung.
I appreciate this program of Nova so much.
It is at once terrifying and hopeful.
Human genius appears to be able to solve the problem of climate change. And Nature herself undoubtedly has the solutions (!)
I won't be here for the changes to come, but I pray for the new generations to have a safe planet to live on.
Thank you PBS 🎉 🕉
I definitely believe (self-sustaining) technology / behavior and more trees can help.
I think the biggest problem is not the technology nor the implementation of it but the question wether we are ready for economical, social and lifestyle changes we need to make it all work.
We could do all of this... Bankrupt the planet, eat crickets, and live like cave dwellers. It would not change the energy output of the Sun one iota.
The problem is we keep adding carbon dioxide to the atmosphere and a change of 0.03% to 0.04% doesn't seem like that much of a change Until you realize that that is over a 33% change.
We've been teaching the "3rd world" to be more like us over the past century or so... ... ...obscene consumers and devourers...
@@craigb8228 The problem is the temp isn't going up. NASA data shows it's volcanoes under the ice shelves heating the water and our global temps are actually lower now than in 1896. We may be actually saving ourselves from an ice age. Who knows? Data rules.
The lifestyle of the top 10% of wealthiest people is generating 90% of the global emissions. Problem is they are the majority investors in new techs and they will fund only R&D projects that will promise them no change in their lifestyle.
I live in Hawaii, and when the sun comes out it gets scorching. I have white canopies and greenhouse style structures all covered in white reflective films and tarps. Stopping the heating of the ground surface and reflecting the heat back up into the atmosphere helps stop the containment of the heat at my place, and can help for the whole planet. But truly, trees and other plants are the best solution. As others have stated, we do need to think on the level of more than just planting monocultures of single species of trees and other plants. I know that is redundant, but it's for those who don't understand what monoculture means, even if most people who read the comments here are well informed enough to know already.
No I live in Hawaii also, the Sun has actually turned white over the last 10 Years.
It’s getting colder at Night and Hotter during the day, depending on which island you live on. But the temperatures are changing everywhere.
The Truth is, the Poles are shifting on its Axis and has been for years as Fukushima is the Biggie for Radiation that is also a problem.
But we can tell that Non Humans Don’t Know the Meaning of the Hawaii Word Aloha🤙🏾 Which Means Respect for Others you Don’t Know🖖
@Levvis Balhare in what way?
Gutmy 5th
Ironically Hawaii has the second coldest maximum recorded temperature of any US state. Only Alaska hasn't got hotter than Hawaii
Trees?
Stupid idea.
Phytoplankton in the oceans remove CO2 from the atmosphere. How about we breed more efficient Phytoplankton?
Problem is... too much and we all die.
In Finland 3 trees have to be planted after every cut out tree. It is a law since like 50 years. Lately, forrest growth is 30% higher than expected. The laser scanners shown here are used to estimate the sice of tree "population". 75% of the country is covered by Forrest now. But in the 70s it was less than half of that. So it can be done and is beneficial for sure. As motivation, half of the forests are owned privately (by individual people). Also, most crops are grown for feeding animals. Reduce the animals eaten and you get less need for agriculturally used land. Don't say people should go vegan but many eats big chunk of meet at every meal. If it would be just once a day, already a big shift could be made...
Although I agree with what Finland is doing, try explaining that to a typical American.
@@fitveganathleteintegrateda1695snow is more reflective than forests. Professional Discourse is not looking for more trees
Really their is no correlation of co2 and global warming so stop talking rubbish 😅
Thank you for your research, NOVA, and for helping find ways to save the planet.
Summer in Texas including this past summer is over 100 for months. No rain. Very frightening!!
Nothing unusual to see here.
Texas gets hot in summer. What a shock?
I wonder what we invented air conditioning for? Refrigeration is far better than the old ice boxes.
Humans should take note of all these information on how to limit CO2 emissions. Planting more trees should be taken seriously. Easy enough to do and the schools should make this a project as one of the kids more important activity.
This will not have that large impact on climate change.
corn is actually more effective in converting co2 to o2 and most plants including trees only convert co2 too o2 during the day at night they emit co2 so if you want to plant trees to store carbon you're going to want to plant natural grown slow growth trees like cedar and redwoods and stay away from fast growing hybrids and grafted trees as they tend to break easily and are more prone to disease/pests
The only way it’s getting rid of by burning fuel and chemicals, we are in that world where we are even eating those chemicals every day called medicines. Produced in Factory, think just what Factories are causing to this planet, we are making same to our Bodies. Good luck guys.
One of the best documentaries by PBS NOVA Thank you, I enjoyed it.
Great to see folks are at least trying.
Yeah, that would be a quite stupid thing to do. What these idiots don’t understand is unintended consequences. We’re much more likely to slip into another ice age. We are not even at the historical optimum high average temp, cooling would make it very difficult to grow food in many northern latitudes. Just stop polluting and we’ll be fine. But, those who scream the loudest do the least when it comes to solutions.
I think with everyone doing their small part and with everything scientists are doing now, we may have a heat chance to reverse enough of the effects of the climate change that we are causing. This gives me hope.
Why not grow mini forests by placing trees/plants/grass, on the top of buildings, in every city? Perhaps even developed a roof, that could serve as mini grass gardens, on people's houses, apartments, condos, etc. I'm sure such a garden could also help keep out the heat during summer, and keep in heat during winter, and thus, lowering the Co2 twofold. If the land is 'taken' by other resources, maybe it's time to start utilizing the vast strata of human cities and its architecture.
Every method helps.
I like this idea 👍🏽
It's actually shown in Wienna at Hundertwassers Building. Google it.
Nice idea. The concrete needed tho’ a garden roof has to support a big load.
As in Japan roof top Gardens
converting carbon emissions into building blocks sounds like it going to take a lot more energy making more of a carbon footprint
and when they crush the rocks to make small pieces the co2 is released
It probably will, just like electric cars are considered "green" even though they ultimately have mega expensive toxic batteries that are charged by plugging into the electric grid and therefore run on coal and gas..
@@realtorjames2586 That's true but the goal is to get the electrical grid green with renewables..
Not if the energy is from nuclear power. Better yet is to use improved reactors like the Liquid Fluoride Thorium Reactor that addresses the problems of current reactors by not producing long-lived nuclear waste, producing a lot less nuclear waste, having no risk of meltdowns and being useless for making nuclear bombs. The fuel thorium is also abundant and currently a by product of mining rare earth metals.
The youtube channel Gordon McDowell has a lot of videos on this type of reactor.
@Just Doit Absolutely not. That's a ridiculous assertion.
This American is not shocked. I’m glad to have him here in this country. Welcome, Harry
One of my real concerns is that the scenario for measuring global warming are temperature which is only part of the global warming if they would put that instead of amount of degrees and put it into a percentage of warming in comparison to other baseline number if they would take an add the temperature that the water has come up the percentage of global warming is much higher than their actually showing because they're only showing the temperature of the air and not the water which is substantially higher in a percentage ratio of the amount that water has become much warmer and expanding area in the depth of the warming also so my estimation is the Earth has warmed at least 2.7 Celsius at this point if you look at the percentage of the warming of the earth most of the heat has gone into the water because it goes through the air
Trees win this challenge hands down, including their ability to produce oxygen and food while their root systems adds to sequestration , and providing sustainable raw building materials. I love trees!
I was thinking the same thing, we are reinventing the wheel a bit. Nature figured out how to balance co2 a long time ago.
Trees and algae are the best way to go. Grow them and burry them deep, than Grow some more, rinse and repeat..
@Chris Townsend agreed that plants need CO2 but if it gets too hot plants shrivel and die!
Goverments around the World need to put pressure on Brasil to stop cutting down so much trees & help them with the ilegal forest tree cutting.. They are destruing the lungs of the planet at a scary rate...They do nothing cuz of greed & power, plus that nazi trump president they have down there that he is just like trump does'nt care about others,the future, climate, just money & power..
Hope that (LULA) wins the presidentual election down there..
I think that we are f****d it's just going to get out of control soon, underground for humans, back to caves...😉🤣
We need to save trees!
Yeah, well think of them as toilet paper, books, newspapers, houses, furniture, etc! There's lots to love!!
As long as we have an economy built and premised on growth now and growth into the futur nothing is ever going to be done about climate change, nothing.
Uhhh, nuclear power literally denigrates your entire dopey post. Yikes
Climate change has been happening ever since this planet was formed
Then, Humans will become extinct. Then, the Earth will recover and the remaining Animals will have good cheer and clean Water and Air.
@@DonZenOfficial We have an incredible amount of nuclear waste all over Earth. That was a bad idea, eh?
Yup. Growth equals increased cosumption, quanity over quality
Techno-Fides - we are feeding our belief in the magic of technology to save our future. - and like Bill Nye says -- "We need to do everything, all at once"
IMO one easy and cheap path is to use the natural cooling mecanism that is convection. Sending hot air in the stratosphere where it will radiate it's infrared faster to space and thus forcing the colder air to go down to the surface. One simple tech would be to instal large conical black structures in the deserts. They would be large enough to heat the surface air and make hot air columns that will reach the strastosphere but small enough to never generate a cyclonic effect, like tornadoes, that would have an impact on the local wind circulation.
Never heard of this. Greening Sahara made me think of it got hot enough to push into Stratosphere?
Creates vacuum sucking up African and Med humidity causing rain
Eventually Sahara gets green and warms earth tho.
I jumped in with my comments before the program was over. Makes me happy that others see what I see in trees and plants. We have rich people buying up our land, stripping it clear, and letting it just sit. Not just a few acres but thousands of acres sitting dormant and bare, or lined up with hundreds of homes so close together that is is almost impossible to walk between. On my property, I planted small pine trees that are now larger. I stopped land erosion and increased oxygen content. Deer and turkey along with birds have a new home too. I live on the boundary of the Great Smoky Mountains National Park in East Tennessee which is called a Rain Forest. It is self sustaining and has its on echo system. Thus the term Smoky which is actually a mist and very beautiful.
Jimmy Fishburn,
Thank you for posting this comment. Step one in creating a desert is deforestation. This happened to my neighborhood over the last 30 years. The pattern goes on and on. People move into a heavily wooded community, cut their trees down, put in grass lawns and the result is a community of houses with yards of dead brown grass most of the year due to draught and winter weather. Attempting to maintain a grass lawn is costly (about $60.00 a month) but is also impossible because the grass is quickly invaded with weeds that choke out the grass. In about one year yards that were initially seeded with grass are about 90% weeds. When the $60.00 a month is added to a $400.00 a month increase in their electric bill the economics make no sense. Due to lawn care costs plus the increase in electric bills to run their air conditioners, the cost of replacing a zero maintenance forested lot with a grass lawn averages out to about $5500.00 a year. Putting that same $5500.00 a year into a ROTH IRA INDEX FUND averaging 10"% interest per year over 30 years, would give the homeowner a tax free retirement nest egg of $995,188.84. Instead of this, most of my neighbors stripped the trees off of their property, put in lawns, and after years of trying to impress people with their lawns, ended up old and broke. Please read my comment under Post Hole Digger.
PHD
You are a benefit to the planet.
Where the hell did you get the info that "rich people are buying up land stripping it bare and leaving it that way"...that's total bullshit
@@douglashanlon1975 Billionaires and big corporations are buying up cropland all over the world right now.
If only if only the world would follow your example. Cars replaceable but technology is repressed
Methods mentioned and listed in the video as new and radical were being trialled and tested in the 1960;s as chem-trails became a thing alongside the contrails. I remember mum and dad giggling at the TV show presenting "NEW" technology of cloud seeding whilst explaining our family were using cloud seeding by 1910=20's.
My favourite geoengineering project is the sun shield. 2 versions. One is to shoot reflective foil into orbit and have automated machines unfold it to form huge strips to reflect the sun. The other similar project is to use ground up asteroids to form an orbiting shield of dust to do the same thing. Both projects would use slowly decaying orbits to reduce the risk of space debris and unforeseen climate reactions.
Go spend some time in nature please .
They should shoot you into orbit
Interesting video, exploring the pro's and con's of each idea. I like that!! Rather than being bombarded with someone else's ideology. A more scientific approach.
Pls use Bamboo for fast CO2 removal. It can grow 90 cm per day. Grows nearly everywhere where there is a lil soil, water and sun. Usable as a decent building material. Thats an awesome plant. 😉
Yes, Bamboo trees are fantastic, and it’s amazing what all the cool things can be built from this type of sturdy wood.
Absolutely riveting and thought provoking. Planting of trees and composting has my vote to limit our emissions as humans. Don't know if the capitalists will put aside their insatiable greed though.
Probably not.
Chana and India have planted enough trees to cover the entire United States. So, yes it is possible. Technology is our allies, not our enemy. Nuclear will be an integral part if we wish to keep our industry from killing large portions of our population.
@@spacescatatford China and India also put out enough pollution to dwarf the US's liability in this.
The only reason climate change isn't being addressed en masse, is because this is a democracy, and the average person does not trust climate change activists, with the constant moving of the goalposts, debunked studies, and oddly political "solutions" for things that aren't even a problem.
1) Like the rise of the global temperature, which is well within in past geothermal activity on Earth
2) The absolute refusal to focus on nuclear energy, which is both clean AND efficient in favor of pushing inefficient industries that they, and all their favorite politicians are invested in
3) The bizarre focus of attention on the US to do something about it, when China and India pollute way more than us, and would be ecstatic for any measure that would cripple our economy, like maybe mandating ineffective energy sources.
@@Phatnaru0002 "1) Like the rise of the global temperature, which is well within in past geothermal activity on Earth" The interglacial maximum occurred 7,000 years ago. Since then we've been gradually cooling down despite cutting forests and farming releasing massive amounts of CO2 into the atmosphere for the last 10,000 years, prior to the industrial revolution, which began about 1760. It took about 170 years to gain about 1-degree Fahrenheit and another 30 years to gain another 1-degree Fahrenheit. At the same time, starting in 1993, sea-level rise increased substantially. Even though James Hansen of NASA had testified to congress was a little overboard, his predictions of extreme weather are clearly coming true. You'd have to be either downright stupid or have your head buried in the sand to believe otherwise unless you are getting a paycheck from the fossil fuel industry.
"2) The absolute refusal to focus on nuclear energy, which is both clean AND efficient in favor of pushing inefficient industries that they, and all their favorite politicians are invested in" I totally agree.
"3) The bizarre focus of attention on the US to do something about it, when China and India pollute way more than us, and would be ecstatic for any measure that would cripple our economy, like maybe mandating ineffective energy sources." Untrue. Solar and wind go hand in hand with 4th generation nuclear. This is the cheapest way forward. It would cost about 15 trillion to run strictly solar and wind with batteries, about 3 trillion to go with molten salt reactors and about 20% less than that to run a hybrid grid. Germany vs France is the test case we needed to know.
@@spacescatatford
1) You need to look further back. Roughly 800k years back by historical temperature measures. I recommend checking the data and research of Dr. Carolyn Snyder, graduate of Stanford, Assistant for Energy Efficiency in the US department of Energy, and one of the leading recognized names in climate science.
We have reached, and far exceeded this global temperature at least 7 times in the last 800k years.
2) Glad we agree
3) This is literally the first I've heard about this solar/wind + nuclear hybrid being effective. I'd need to see more on it first. Where did you hear about this from. Sounds like another theory, which I take with a grain of salt considering wind and solar's track-record for efficiency.
Great video.
Thanks for sharing.
I will say, I'm not keen on adding even more into the atmosphere in an attempt to reflect the Sun's rays. Haven't we learned from the events of colonizers introducing animals to conquered territories with great destruction?
And, last I checked, these problems have not gone away.
From rabbits and rats, to Aisian carp. Bit of a problem.
And yes, trees.
(They're amazing!)
Would love to have the tree and grass land project links so we can donate and support this brilliant work
Let’s not forget the record deforestation we had this year .
The fires in the Amazon region in 2019 were unprecedented in their destruction. Thousands of fires had burned more than 7,600 square kilometres by October that year. In 2020, things are no better and, in all likelihood, may be worse.
the ozone hole, toxification of the ocean, the clearing of the rainforest,...what this means is that the human race has almost always behaved like garbage and that if anyone treated us the way we treat everything else we would go to war and kill it
@@straytarnish9443 Ozon hole was a lie as it gets smaller and bigger with temp, has nothing to do with temp. The rainforest you need to talk to the people there. Nothing wrong with the ocean, you one of the people that really think there is a plastic island?
All it took for the year without a summer (1817) to happen was one volcano in Indonesia to go off and produce massive amounts of gas. We have zero control over this planet. The planet’s just gonna do its thing. We just need to be prepared for whatever we can rather than trusting in tech & science gods or government gods. There’s only ONE God who can make this planet work the way He wants it to. We don’t get much a say in this.
@@rachelczumaya2806 god is a douche. Please stop wasting society's resources , don't go to society's hospitals , rely on your precious god
@@jimlincoln1283 no it was real and CFC r12 was banned because of it. yes the ocean is becomming more acidied due to global increases in co2 emissions. The last mass extinctions also were caused by co2 emissions and it acidifed the worlds oceans killing off most of the worlds vertibret.
A beautiful presentation NOVA, but missing from the equation is the consumption end of energy. As Amory and Hunter Lovins point out, the lowest hanging fruit are in energy savings within easy reach. Ordinary things like insulation, white rooftops, newer doors and windows, effective mass transit, better manufacturing processes, heat pumps, etc. coupled with much more efficient use of planes, ships, autos and trucks, and intelligent lighting can drastically reduce consumption while improving both the quality of life and lowering manufacturing costs. Capturing and storing carbon becomes much easier when there is less being emitted in the first place.
No offense but those solution are about 40 to 50 years too late....the patient has Ebola and we are trying to treat it with aspirin.
We have learned the hard way that sealing buildings tight and riding crowded buses are great ways to spread COVID and other respiratory infections. There is a real conflict between measures to fight global warming vs. measures to fight respiratory pandemics.
@@stevenlitvintchouk3131 Boy have you got that right...I work in the HVAC industry testing systems and buildings. We test the building envelop to ensure it not letting unconditioned air in or condition air out...and now because of COVID a lot of buildings HVAC systems is starting 4 hours before the building is occupied. The system operates at 100% outside air to flush out the building...this is done regardless of the outside air temperature, adding up to a third more energy usage...It's really nuts.
I think we are starting to have the right attitude.
We have to aim at controlling our planet … other planets await us !
We talk about terraforming other planets, let's already start with ours ! we must learn to control our planet, to curb in this case the heating so as to stabilize the temperature rise.
Very good reportage NOVA. Thank you.
I bought my property in 2016 and it was 2.7 acres of mostly grass. I’ve planted hundreds of trees and let parts of it grow naturally. My property is already cooler and it only took 7 years to have fruit and what looks like a forest.
We don't know who struck first, us or them, but we know that it was us that scorched the sky. At the time, they were dependent on solar power and it was believed that they would be unable to survive without an energy source as abundant as the sun. ~Morpheus
If we don't want to do that then we need wide ranging reform like yesterday.

Twenty years ago I saw a bumper sticker in San Diego that said "trees are the answer". It was distributed by an organization called the Friends of Trees. I have been an advocate of increasing trees everywhere since well before that. This has not been a secret in any way. Funny story, I went to the friends of trees office in San Diego and walked in. Out front, directly in view of the front counter through a sliding glass door were 2 trucks owned by the organization with the bumper sticker on each one, facing the door. There was a stack of the stickers on the counter. A lady was behind the counter at a small desk, and I asked if I could have one. She was completely clueless, had no idea the stickers even existed! But there are other ways to help. Making roofing reflective is another small way to help. Anyone who has been in an attic knows how hot it gets This heats everything around buildings at ground level, helping to heat the surface of the earth, which holds the heat in far longer than reflecting it back into the atmosphere. Likewise all the asphalt pavement. The list goes on and on. And of course, 7.6 billion humans as opposed to a number like 1 billion is so obviously making the problem...7.5 times worse. No one wants to talk about population control/reduction these days. Corporations also reduce trees because of the mess created by leaf fall, insect and bird inhabitation of trees, the expense of trimming them etc.. That cost is the main reason in reality. One of my pet peeves over the decades has been that in parking lots of large retail outlets they keep trees to an absolute minimum to reduce this mess and the expense of periodically trimming the trees. Combined with the predominance of asphalt in such parking lots, it adds it's own contribution to the problem, and of course adds to the fun of returning to your car to bake at least for the first few minutes. Not to mention the children and pets that die each year from being left in cars in parking lots. Many people are waking up to these sorts of realities created by our selfish, instant gratification addicted society. Let's hope thoughts like this gain popularity in the very near future.
Wow I really appreciating who invented like this technology that kind of technology that I want
I know what we are doing is crazy, but to change the atmosphere with some of these ideas is scary. What could happen? What could be the unintended consequences?
Your instincts are correct. At least with pumping sulfur dioxide into Stratosphere
Tears apart ozone layer brings back acid rain
I wish they had suggested a list of what individuals can do and organizations to contact...They also did not emphasize enough that we need to consume less of independent variables that add to the problem....Nova is great.
Trees .. 1 per person
@@videosaala I agree.
"MAKE MORE BABIES" was not emphasized, because, "MAKE MORE BABIES."
i think this one may be self explanitory. maybe the first step is self educating on the things in your life that generate greenhouse gases like co2 and methane. perhaps once you know, easy and obvious solutions will start becoming obvious. for me, i live close to work, lets cut back my trips to work via car, with something more sustainable, and it also gives me excercise. another one is my diet. cows produce heeps of methane, which is 10 times worse then co2 as far as greenhouse gases are concerned. perhaps maybe finding ways to cut your meat intake, and try to incorporate foods into your diet that you have grown. its very rewarding and much healthier of an alternative then dead produce from the supermarket. i think the key is anything you can do sustainably
@@p-san Maybe we should genetically engineers our cows so they produce less unwanted gases! How rude of them!
Years ago I had a science teacher that educated us on climate change and what was to come, but interestingly she said if everyone on the planet planted just one tree, it would be enough to clean our air. A little effort goes a long way was her point.
April 28 is Arbor Day and decades ago it was a requirement in all schools for the students to plant a tree. I personally would love to see that come back - I know I will keep planting them!
I had teachers that nurtured free thought, they were great. Remember the ozone layer
Any effort put it in by you or anyone else around the world, planting these trees, wouldn’t amount to 0.0000000001% of the goal you would need to get to, to make this worth while. Stop wasting your time.

Very little is being said about the two obvious major contributing factors of global warming: human overpopulation and deforestation of the planet. Reversal of these trends is needed. Expansion of Earths forests could reduce CO2 without more energy consumption involved in others proposed solutions which only address the results but not the root causes of global warming.
I hate to be a Debby Downer, but James Hansen et al (2013) estimated that reforestation would only be able to recapture about 100 Gt of carbon, whereas we are emitting roughly 12 Gt C per year, so a global reforestation project would only capture 8 years of our current emissions. The only solution is to STOP burning fossil fuels as fast as possible. Every country needs to create a plan to get to 100% renewable energy in 15 years and to get to net zero emissions in 25 years time. In the US, that means defeating the Republicans in every election and holding the Corporate Democrats feet to the fire.
Omg, just this morning i was thinking about this exact thing. Knowing that the polar caps are unthawing faster than ever, i was thinking why can't we grab some water from our oceans. Have a sort of pipe line to the poles where the water will be able to freeze. Yes we will need some air freezer machine of some sort.

Why are the benefits of a slightly warmer planet and higher CO2 not even discussed? How low can we go?
Plant-based materials > naturally inherited technology that requires no additional research. Advantage is that plants continually intake CO2 while alive, so you can maintain natural ecosystems and create an engine for CO2 capture that also generates food and or physically useful material plus 02 (what humans breathe to survive) as byproducts. you can use plant materials for building useful and durable products, thus locking in more CO2 into things that are actually valued by people.

Real world fact, during covid lock downs the effect on air quality and the natural world was dramatic in all the best ways. Nature responded with resilience proving that decreasing emissions on a personal and global effort needs to be a real world goal for everyone.
Covid was a temporary 7% global drop in C02 emissions, so back to 2019 levels before increasing again the next year. Methane and N02 are trending higher. The only other reduction since WW2 was 2009 by 1.9%. In other words, green house gas emissions are correlated to GDP. However, the clear air from less industry actually increased solar radiation reaching earth, while the many forest fires increased C02 emissions from natural sinks. This proves that effort and goals are not outcomes, it’s more like playing make believe.
That's because the lack of jet exhaust mainly. it has nothing to do with us land dwellers
The Jedi, a spiritual solution. Double food production. No problems, the optimism is contagious
The good news is that our beautiful planet will survive and thrive even if we extinct ourselves through stupidity.
Sequestering carbon back into topsoil solves many problems we are facing. We just need to change our buying habits to encourage the farmers using no-till, pressured rotational grazing, silvoculture, etc, via permaculture techniques.
Let me preface by saying I'm not a climate denier and global warming is real. There is a battle of sciences between alarmists and deniers and everyone thinks they need to pick a side. Both sides are both right and wrong. The earth is warming due to human activity, so the alarmists are correct. However, the earth has had far higher c02 levels in the atmosphere in its history and didn't heat up the planet. Many of the high c02 eras were even during ice ages.
The real problem is humans have spent thousands of years desertifying the planet. If you look at ancient civilizations, all of them (except those in tropical areas) are located in deserts. Since civilization would not and could not have began in the deserts, we know that they were once green lush lands.
Civilizations cleared the lands and diverted rain water away which ,in time, turned the lands to desert. We are still doing this today on a global scale. Once the soil dries vegetation dies out the land becomes desertified. Then we dig wells for water. Once the ground water dries, we dig bore wells. Once the aquifers are dry, we move to a different location. We need to stop rain from leaving the land, and allow it to soak into the ground. This allows vegetation to cover the ground and cool the climate.
In nature, rain water never makes it to rivers and streams unless the ground is already saturated. Rivers and streams should almost always be caused from ground water seeping into them.
@@IowaKeith
I get it. I know that the fractional CO² increase is there, but that C0² only exerts 4% *effect* in the overall weather patterns. It is a fraction of a fraction.
I think we could solve for other problems while solving for global warming concerns. Methane harvesting is one as it solves several problems for people in developing countries.
I agree with Walter Jehne's three prong approach where we:
1) Greatly increase rainwater harvesting earthworks, curbcuts, and bioswales for flood mitigation, hydration of water tables, bringing back river, regreening especially with trees, reducing power grid strain by reducing the need to pump as much water, decentralizing water (adding to water accessibility), etc.
2) Planting site-appropriate trees to restore nature, increase food for people, as well as providing another foods ourselves for livestock and wildlife; additional transpiration; cooling of heat island effects; to preserve paving; making cities walkable and bikable again; water pollution reduction; etc.
3) Rebuilding soil health. When you rebuild soil you are naturally adding soil carbon, increasing plant growth, infiltrating more water into the soil, etc. You are reducing entropic cycles and replacing them with ones that are exponentially more efficient recapture cycles.
I think we are largely in agreement regarding your statement.

@@brucegeorge3208 What do you think is keeping the heat in place? What do you think protects us from the sun? The atmosphere... which is getting polluted by emissions.... The sun is also keeping us alive. Its not fear mongering when the planet actually has these problems.
No not really.
The radiation from the earth has long wavelengths that are trapped by greenhouse gases, so the energy radiating from the earth does not escape easily.
However, if you stop visible light from hitting the earth altogether, it will travel directly through our atmosphere into space. And not warm it.
We need to turn the light around before it is transformed into infrared radiation. Cos we can't get rid of that.
No more rain due to lacking of light from the Sun?
That is an interesting thought, but no, it doesn't work that way. The amount of heat coming in from the sun is massively more than all the heat generated by the earth and humanity. Hence "snowball earth" events and the concept of a "nuclear winter". Even the eruption of Krakatoa lowered average temperatures for a short period. Check it out.
Trees, Trees, & more Trees Please !!!
It won't be enough at the rate we are at.
Believe me as I was one of three men who planted over a million trees in the northwest and our tree's had a 98% growth rate . I have been back to some of the places where we planted these trees and seen how well they were doing from tiny seedlings to trees over 30 feet in growth and I feel very proud of what I helped to accomplish . How many have you planted in the wild ??
Good show, I believe that We can do anything we put our focus to, Regenerative agriculture, the way we eat and produce food is a big part of this, Restoring Prairies, Wetlands growing Hemp, Bamboo, Kelp,,,,,,
FYI trees and other plants, including ocean plant life, give off carbon all the time. All that captured carbon gets released.
When the decompose, that includes leaves etc, the decomposition process breaks matter down to its basic 4 element for life, the largest in quantity with decomposition is carbon.
Also, have you been to a rainforest, they are hot and humid and attract rain.
If we did add new forests where we didn't have trees, we will most definitely would increase the the global temperatures. Polar caps would melt, oceans would become more salty as freash water would be held in the atmosphere and disbursed to the mega forested areas.
And the atmosphere gas composition dramatically.
Trees actually do produce cooling. Both real cooling of the ambient air through evapotranspiration, as well as creating shade. That shade can be used to reduce the need of air conditioning which saves energy and thus carbon emissions.
@Omni0404 First of all, have you been to the Amazon?
Deciduous trees only produce shade underneath them. And only when they have leaves.
Conifers, on the other hand, don't provide shade. In an older forest that say has 3 story Lodge Pole Pines do produce shade however if you are in a conifer forest, you will notice that they trap heat and that stored heat can get warm enough that you can feel the heat radiating off of them.
Go on a hot day 30 degrees Celsius in an area full of Conifers. It is hotter near the tree and cooler the farther away you are.
If you lived in an alpine area predominantly made up of Conifers, you would know this.
I am not going to explain why Conifers behave life this. You can do your own research on Conifers and alpine ecosystems. And how they are designed to trap and radiate heat.
All ecosystems have their roll on a global scale, including tundra, deserts, sage grasslands, wet lands, glaciers areas, and heavily rocky areas that only support moss and lichen.
Not to mention you can not grow trees on the oceans, seas and lakes either.....🤣
@Omni0404 regarding trees to cool your homes, this only works if you have enough trees, taller than your home , close enough to your home, surrounded your home.
This isn't always as practical as it sounds, and there is a safe distance from how close to your home you can plant trees, and often how many trees you can have.
Then, you need to account for your water usage bill and sewage that the city has to process, and disposal or composting is required.
Disposal means it ends up in a landfill site. Composting produces CO2 emissions.
@@AmandaHugandKiss411 Thank you for admitting that trees do produce cooling and that all trees block the sun 😁. That was some intense face saving behavior from you. You missed out on a lot though. Why do you think a tree has to be taller than a house to provide cooling? Do you not know that the sun has to rise and set before it reaches its zenith? You would be amazed at how much heat is transfered being in direct sunlight. By lowering the amount of time your house is exposed to direct sunlight there is a significant drop in temperature.
We need both the north and south poles stabilized. High altitude reflection. The reduction of sunlight would reduce the temperature. We need a higher difference between cold and hot temperatures around the poles.
Stratospheric sulfer saturation.
@@tonyd2919
De-globalizing won't stop the progression of AGW and cool the planet.
We are currently feeling the effects of early 1990's atmospheric carbon saturation.
The effects of AGW will increase relative to the increase in atmospheric carbon during the last 30 years.
Sulfur dioxide suspended on the stratosphere in the lower mesosphere would have immediate cooling effects as it approached the desired saturation density, by reflecting UV into space before it can be absorbed, converted to IR and trapped by the carbon saturation in the troposphere.
How would de-globalization do anything anyway, when AGW is a global issue?
You were cool with the "tech" that we knew would get us here, but now you're afraid of tech that would stop us from suffering the future increase of AGW effects that are already baked in by the current atmospheric carbon levels, without it?

The fossil fuel pollution of AGW isn't a failed science experiment, it's the result of a destined to fail pseudoscience disinformation campaign by the fossil fuel industry in the interest of their huge profit margins.
They have always understood the science of AGW and know it's true.
They just don't care, motivated by sociopathic short term greed.
Don't get distracted by conspiracy "theories".
Anything that sounds like the plot of some sci-fi espionage movie is virtually certain to be nonsense.
Just ask yourself, how many people would need to be knowingly involved in said conspiracy.
The chances of it being exposed increase exponentially and the time until it's exposed decreases exponentially with every person involved more than one.
Bill Clinton was involved in a conspiracy that was exposed and resulted in a two year investigation and impeachment.
That conspiracy only involved himself and Monica Lewinsky.

Great documentary, very informative. It has some great ideas but I have to say I don't like any ideas that adds anything to the atmosphere. Earth atmosphere is a balance that man should not play with.
Well you are exhaling C02 millions of times over your life so......Its not realistic to try to freeze the state of the Earth right now. The ecosystem and climate are dynamic and do go through changes whether we are here or not. The problems that worry me are ocean acidification and the Clathrate Gun Hypothesis creating a positive feedback loop of global warming. We should make our entire transportation industry (minus aircraft) electric....and we can do that, but we will always have an affect on the environment.
When rain from those cloud over the sea hits land it will destroy all the trees and vegetation not all plants can handle salt water... the focus shouldnt be on messing with the sun or atmosphere but by replacing what we did ourselves... Replant more trees millions if need be...replace the ecosystems you destroyed and things will turn around.. Stop polluting if there are enough trees even the waste from production plants as long as its CO2 emissons will begin to be negated again..

Why don't we use if for what it is good for, trap heat?
And I have a question: did the Apollo 13 capsule have a temperature problem too? I don't know.
Make huge airpurifiers, like the size of skyscrappers... place them around the owrld and controll the weather forever.
When I was 6 years old, I was riding in the Plymouth with my parents. It was winter 1972 in Chicago. I asked why all the cars had white smoke coming out the exhaust. My dad explained it was steam from the heat in the exhaust. Then there was a long Q&A session. I had a lot of questions about cars and heat. After pondering it for a while in my 6 year old mind, I asked. "Will all the cars on the planet make the planet warmer, and then it will be summer all the time?" My dad said no. My mom explained that the planet is so big that cars will not make enough heat to change the weather. After pondering that a while, I asked. Well what about all the heat from all the houses and buildings everywhere?" Once again I was assured by my dad everything would be ok. After a short pause I said. "I doubt it. There's going to be a lot more cars and buildings in the future." There was silence in the car.
As with most junk science advocates...sounds great and even somewhat accurate. However, the reality is moe in favor of your mom and dads answer. If not for the fact that there is NEVER a static scenario where technology and our discovery allow us to become stagnant and unable to adapt accordingly. Always remember necessity is the mother of invention. Geological fuel sources have only been driving our economies for about 100+ years. Halfway into that timeframe we have discovered how to go to the moon and harness the atom for energy as well as battery powered tools. Point is, our technology will ALWAYS drive faster than the alarmists dooms day scenarios. Ask any one of them to implement all the science as well as the biologies to map out a solution and they become dead silent. We still know little about this planet and it's ability to do what it does with the resources it has much like a neurosurgeon has mor questions than answers about the human brain.
Adding, humans love to do what's expedient in the moment, ignoring future consequences. As a sad example that may end our lives with war, Nanci Pelosi as you know goes to Taiwan to support democracy over attocracy. WELL, WHAT THE HELL HAS THE U.S. BEEN DOING MASSIVELY IMPORTING GOODS FROM CHINA FOR NUMEROUS DECADES NOW, GIVING AUTOCRATIC, COMMUNIST CHINA MASSIVE MONEY TO GROW THEIR MILITARY. I mean how stupid and false is that, if we really believe in democracy over attocracy.
AND, that doesn't account for the fact that any time you have a trade imbalance between 2 countries, the lessor-trader is mortgaging their future away, selling away their future; it's exactly like being addicted to a drug -- let me have a good feeling now, for huge pain later.
And finally, that also does not include giving China tons of manufacturing secrets and technology over decades.
... just another example of how horridly short-and-dumb-sighted people are.

Double check your sources.
Fossil fuels have been used on a global scale for around 200 years, not 100.
Continuing to introduce more artificial solutions into the atmosphere only adds to the problem.
WOW, someone almost gets it!
You're an Environmentalist, too? 💙 I'll be doing this "til the Love runs out". That last part are song lyrics.
Your 100% correct. But millionaires are made from this lie so it's ok.
For the cloud brightening with aerosolized salt water, I wonder if the aerosol / air could be heated to make it rise into the clouds? 30:48
What about an array of solar panels to block the sun in space & too collect electricity at the same time?
This will only work if were doing it together.
- Lower the need for industrialization (more recycling).
- Put laws in place that if you want to open up a factory you have to place a CO2 absorbing machine that stops your factory emissions.
- Stop/Lower Deforestation or make it so that for every tree that you cut down you have to plant a new one (put a non corruptable system in place that will supervise everything on hands on level)
- Make use of algae in oceans to help lower the CO2 levels that is already in the atmosphere
- Plant more CO2 super cleaner trees
You know trees release CO2 as well right?
@@huggybear3098 please read all of the bullet points that i have placed. Or search up the meaning of deforestation.
@@mrcederboom1 they're pointless and meaningless and plants give off CO2...you do know 63% of CO2 is stored in the ocean? You do know CO2 is at one of its lowest points in the history of the planet...you do know CO2 does not cause global warming..case in point the last 5 ice ages atmospheric CO2 was between 1800-6000ppm ...you do know Scotland cut down billions of trees for environmentally destructive wind turbines.... you spew left wing rhetoric verbatim....
None of these alternatives to clean energy and stopping the production and use of fossil fuels has any realistic potential. This is mostly greenwashing from the fossil fuel industry. What I would like to see is who are the organizations funding all of the "carbon capture" and geo-engineering projects. That would be an interesting list.
Not sure if the fossil fuel industry wants carbon capture either. If carbon capture tech becomes scalable then these companies might be required to pay for the installation of these technologies. But you are right that without expanding clean energy capture none of these technologies really do anything.
100% agree with you!
İt won't matter we are crossing peak oil , and absolute peak technological advancement , get ready for the worst side of humanity winner take all , earth stripping pointless race to the bottom world wars .......
I think this research is something the fossil fuel companies are funding, just to be at the forefront of energy production.
Agreed. Unfortunately when an outlet like PBS can be captured to sell this green trash there’s little hope to stopping carbon emissions.
Reflecting sunshine is to risk lowered plant food production and freezing winters…or would it be a continuous winter world wide?
Rather than store the CO2 why can't we utilize it to create stone for building materials and housing or would that require too much water?
Outstanding documentary!
Can We Cool the Planet? is not only ambitious in its charter, but covers major issues very well-- and with new material about innovations that give us hope.
Thanks, especially, to the compelling army of climate advocates who show we have a future.
You have NO future, only mindless delusions coming from a warped mind. Grow up. Humans have destroyed the earth. Our course is set.
Reforestation is a cool idea. And WWF seaweed farming has shown promise for creating a useful and natural carbon sink that also has multiple uses. Both are done inexpensively by locals with local pay offs.
the big companies working on these projects cant make any money back doing it that way
@@Grandassets Which companies are those?

They need to go after China
@@christopherabraham9121 Cannot do that ! Then they could not get rich off of the cheap crap the make for them . Oh China owns most of them !
I like the idea of massive tree planting. But first, we must stop burning the forests!
dig away sea floor and make snow white mesas in huge areas. displacement, reflection and water harvesting
This was actually a really good watch. I like how the problems potentially caused or noticed from one potential solution led into the next potential solution and so on and so forth. Thank you for leaving it off on something of a hopeful note to stave off the existential anxiety lol.
A good watch? You mean like a Timex? Or a nice gold retirement gift? A good watch. HAHAHAHAHA!
WORLD POLLUTION
FORMULATED MICROCRYSTALLINE WAX WILL CAPTURE THAT BLACK CARBON SPEWING FROM THE WORLDS INDUSTRIAL SMOKESTACKS
The solution for capturing carbon was discovered in my lab and candle shop over 40 years ago. I knew back then that this was going to come to this day. I had to search for the answer and did. The heat loss from a smokestack can be forced or harnessed into a large tank containing hot liquid microcrystalline petroleum wax. The heat will keep the wax in a molten state which facilitate the carbon to be absorbed when combined with the wax. Carbon when mixed with wax reacts like a dye. The wax-carbon amalgamation will result in a black wax solution thereby making it impossible for the carbon to escape into the environment while in a liquid state. Other toxic particles are also captured in the wax settling at the bottom of the tank as a sludge. A sludge release valve is located at the bottom of the tank. After the sludge is removed more wax is replaced in the tank working something like a toilet. The sludge becomes a byproduct that can be used as an additive to asphalt for roads or used for cocooning nuclear waste materials for long-term safe burial. The entropy of the Earth has been increasing at a startling rate since the beginning of the industrial revolution caused mainly by the carbon that is released into the atmosphere. Government scientists have failed to stop and prevent carbon pollution from entering the environment. This problem can only worsen until a solution is found before this problem becomes irreversible. It has been discovered that formulated wax has been shown to be the only answer to this problem.
PREVENTING SPREADING RADIATION:
This formulated wax will also help prevent the spread of radiation such as preventing the escape of Plutonium dust particles from nuclear reactors or from structures or buildings housing radioactive materials. In 1994 This method was successfully demonstrated on the Sarcophagus of Chernobyl's blown-out reactor # 4 that was leaking Plutonium dust particles through open seems. In 1995 formulated wax tape was used to cocoon radioactive metal that had spat out of the reactor at the time of the explosion for safe long-term burial. In 1993 a wax membrane method was used in the yard of an abandoned house about five miles from Chernobyl to demonstrate how to reclaim radioactive contaminated territories for re-cultivation.
I have been researching wax for solving mankind created environmental problems since 1969. As I aged, I discovered many other uses for wax such as making candles or replicas of people's hands. This led to coating the hand castings with latex rubber. After the latex had cured, I inserted latex rubber tubing a quarter of an inch tubing in the tips of each finger that was sealed with the latex. After the latex had cured, I was able to pull the end of the tubing that caused the fingers to contract. By pulling the ends of all five tubs the hand would close or grip and was able to pick up things such as a pencil or jelly beans just like a normal hand would do. The end result would act like a normal hand. I was able to color the hand to match the color tone of the hand that I replicated. The end result was a prosthesis hand. Through the years I have discovered many other uses of formulated wax for solving environmental problems: Here is a list of confirmed uses since 1969.
OTHER USES FOR SOLVING POLLUTION PROBLEMS USING WAX:
• Remove oil spills from dry or wet sand, soil, water, ice This method was demonstrated for the Canadian government in 1974 to remove oil from a beach on Passage Island. This method was demonstrated to the US Coast Guard on two occasions, one in Hawaii and the other in the state of Texas demonstrated to the Canadian Coast Guard on two occasions. Oil can be removed from beach sand as though it was a giant carpet More demos were shown to the Canadian press on three occasions.
• Preventing radiation leaking from reactors, buildings, and storage facilities. This method was used to prevent Plutonium dust particles from escaping into the environment from open cracks and seams on the Sarcophagus of Chernobyl's blown out reactor # 4 in 1994
• Cocooning asbestos coated pipes wiring for safe removable This was demonstrated in the basement of an apt building that has 319 feet of loose asbestos
• Cocooning radioactive waste for a long term safe burial. This method was demonstrated in Chernobyl by removing a 4” x 5 ‘ rusting metal tubing that was buried and coating half the tubing with a special microcrystalline wax and then re buried.
• Removing radioactive contaminated hot spots from soil surfaces approx. 4 feet square in Chernobyl in 1995
• Preventing uranium mine tailing particles from becoming airborne in 1987 by laying a wax membrane on the mine tailing surface in Elliot Lake Ontario.
• Preventing radon gas from entering into homes or buildings demonstrated on three homes having very high Radon levels where 95% of the Radon was blocked.
• Preventing crushed coal dust particles from escaping moving open rail car trains was demonstrated in 1975 by spraying hot microcrystalline wax on the exposed coal surface to prevent the coal particles from becoming airborne while the train was in motion.
• Preventing fly or bottom ash pile dust particles from becoming airborne Removing bunker oil, diesel fuel, gasoline transformer oil demonstrated for Ontario Hydro in Kinston Ontario in 1991

Why spend a fortune on a non-problem? Because this is what the WEF has planned for us plebs. It is good for their power and business.
No, they'll kill us all. It's all bullshit. Where are the model runs made in the 1980s? How accurate did they get 2022?
Whether or not climate change is real, it also a racket. Each one of these shows tries to be MORE hyperbolic than the rest.
There was a documentary on how great the planet was coming back to life when covid 19 had taken over the world. The water was getting so much cleaner, the ocean was and the air quality was so much cleaner around the world. Yes the planet can be saved all that has to be done is us with all the stupid stuff in this world that none of us need....
@@joaocosta3374 yes an there's to many people on the planet

Geoengineering is indeed a really scary option - but then again, aren't we doing it already since the 1820s?
I guess the 2023 and the 2024 El Nino summers will push us for rapid adaptation measures and I would not be surprised to see some geoengineering sooner than anyone thought possible - knowing that the Americans won't accept having a Katherina-strength hurricane every second summer on the lower East Coast...
