Congratulations on making it to 1,000 episodes! Looking forward to it!
Like every other inaccurate video, BBC shows steam coming out of cooling towers when talking about CO2 emissions.
As odd as it sounds, water vapour/steam is actually the biggest greenhouse gas. Although it doesn't actively break down the ozone layer, it absorbs vast amounts of IR radiation (heat from the sun) and keeps the temperature rising. CO2 is just breaking down the little protection we have left. Powerful combo, I guess that's why they had it in the video.
You also missed the stacks next to Cooling towers which are the source of various green house emissions from Thermal Power Plant.
Thank you. We still need to plant as many trees as possible - select native or endemic, indigenous plant species. We also need to remove all exotic invader plant species.
Talks about CO2 emissions - shows nuclear facilities emitting vapour. I'll never understand this.
Yeah lol, Isn't that just steam?
Weeelll, what you are seeing there is a VERY potent agent of the greenhouse effect. 😉
Nuclear energy is one of the most underrated energy producers, only the radiation things cause fear but modernizing some old rules and maintaining the plants will be a crazy efficient and cleaner energy source
Coal/gas power plants also use cooling towers! Look, there are also normal chimneys there. That could very well have been a fossil fuel plant.
BBC numbnuts think they can fool us with this
Can't wait for the 1000 episode

@paulcartertv
And congratulations BBC click on your 1000th episode.
Congratulations!!! Excelent show!!
I LOVE THIS SHOW. CONGRATULATIONS
Congratulations for reaching 1000 episodes!
Why not start by re-planting trees and stop cutting down forests and destroying local natural ecosystems which include vegetable material which naturally soak up the harmful greenhouse gases, the urban landscape is a great place to greenscape. Semi-arid areas could also do with re-planting.
that alone wont be enough, not to mention that trees takes decades to fully grow to then store carbon. Not saying we shouldn't do it, but claiming theres an all rounder simple solution is delusional and there needs to be work on all fronts with immediate effect outside of these halfassed responses.
mature forests are at dynamic equlibrium you fool...
cutting the trees when they passed peak growth and replanting new seedlings for them is better actually, then you use to wood to build houses....
also you need to "clean" forests for max growth efficiency and storm hardiness, you need to take trees down...
Forests are temporary carbon sinks not a permanent one! If forest catches fire, all the carbon stored for decades would be released in seconds! If trees decay because of flood, carbon is released back. That is what is happening now. Rain is random, so forests are not dependable sinks any more. Trees also take a long time to grow and absorb co2. A plant takes years to grow and start absorbing co2. Every year we are releasing 40 Billing tons of Co2. So, if you plant a tree today, by the time it start absorbing, we would have released 100 times that. Overall the plan should be rapid switch over to solar from fossil, absorb co2 artificially and naturally by reforestation. All these are trillion dollar investments. Young entrepreneurs should be motivated to make this into a business venture rather than a philanthropic effort.
Many countries in the world have already started replanting decades ago. And ecologists argue that still this is not enough. Your comment is just as ignorant.
Congratulations @BBCClick for your 999th Episode....
Always interesting...
Can't wait for the 1000 show,...
there are FAR more effective methods of climate control than carbon capture, which is horribly expensive
The solution is not climate control. Control freaks are what destroys us. The solution is to take a chill pill. But who wants that? Too boring. And so people become what they fight, manifest what they allegedly oppose.
Great show as usual 👏👍999 shows👌
🥳🥳🥳 I am really curious for that next episode! :)
please can you share the old videos like all 1000 episodes on youtube , I have been watching click for a long time like 15-16 years , click is the best place to get info about new tech, but there are certain episodes which were shown about a decade ago and still are not a reality, somebody may watch them and get inspired to bring those ideas to life
Do a story on ships dumping their black water tanks before they arrive in port to lower cost. When they arrive in port they have to pay to have those tanks pumped. But they're not stupid. If they totally dump they know they will be fined so they dump a majority of it which means a lower rate they have to pay to the deposal company. Shipping is vital to the world but the way they go about it is worse than most other pollution aspects. Where do y'all think those floating plastis islands come from? Not most of us. When's the last time you threw something away in the ocean? I bet almost never.
Very interesting report about EMSA. We need to focus on drone technology in Europe for reasons like this. Why buy American when we can do better ourselves?
Covering the Mideast in rock containing CO2 doesn't sound like a bad idea.
It used to be steam power , then it was the internal combustion engine, then it was electricity, and then it was atomic energy. Now its "TECH". And the answer is "probably not"....
How about planting trees and other such things, as we need to be growing more things. There are many that are burning down rain forests, and there are many other such things going on.
DId you even watch this?!
@@tams805 yes, but this little drone is only to check ships. It does not filter the air plants do that for sun soil and water.
It's so upsetting to see the guy at 15:00....
Let me rephrase that, it's so upsetting that we don't have a solution for people like the bloke at 15:00. Lab grown limbs, or synthetic ones, or... Something I can't even think of, a solution for him, and those like him, should exist in 2019!
It is magic! No chemistry, no thermodynamics, no physics. Pure magic
Great show as always, very interesting reporting. However, in the talk of climate change and what we need to do, I never see much reporting on what is going on in South America, India, Russia, and China. Would it be possible to focus on the non-European or North American efforts to tackle this crisis? We're all in this boat together.
It's not scalable and the cost is. Very prohibitive. Trillions, preserving our wild forests jungle and planting trees must be a major part of the solution . But we've got to stop polluting.
there is more advance technology that provide by nature it self, this tech called "TREE" and "KELP"
Do you speak for the trees?
@@eliasstorhaug535 i guess, i am
You just read my mind there
I wonder what will happen to all the people studying dance, when someone replaces them with robotic lifelike figures. I guess it would cut down on the number of physical injuries .. .
When humans take down the clean air to cut the solar energy of 01 (the machine city)
When I was a kid I dreamed about big fans sucking the pollution out of the air.
Cheap way plant more trees..
It makes far more sense to plant real trees than "artificial trees". The scientist who prefers his technology says trees need more space. But that's fine. We've got lots of space. Take a look at Russia, the biggest country in the world, and yet the vast majority of it is completely uninhabited and mostly grassland. It could be forested. At the same time, we should be bringing trees back into urban environments, mixed in and amongst the buildings.
The alternative of filling these spaces with "artificial trees" is both far more expensive, and far less desirable.
Forests are temporary carbon sinks not a permanent one! If forest catches fire, all the carbon stored for decades would be released in seconds! If trees decay because of flood, carbon is released back. That is what is happening now. Rain is random, so forests are not dependable sinks any more.

@@rsamblee Temporary eh? What do you think the carbon that is trapped in coal and oil was when it was first captured? That's right, biological material such as trees. Fossil fuels are prehistoric forests.
The carbon captured in trees can be released quickly, or slowly. It all depends on conditions. And it's usually a bit of both.
This isn't theoretical. Planting trees is the number one way of capturing carbon in use today.
This channel need subtitles... please. thanks.
Sir I beg you to please please help me right now I am stuck in a problem in hurry i downloaded some wallpapers from the smartphone homescreen Google search engine but I can't find them in Google photos I think my wallpapers are still present there becoz when I download them again then they appear in double or triple copies so please help me to trace and delete them as soon as possible thank you for giving me your precious time
go to hell!
@ Don't spread negativity.Shame on you.
I got a really good idea.. but idk how to.... get it out to a company for mass production..
Create a company yourself and realize it.
we are all tech
Carbon capture... rather like the sea does?? CO2 is not a greenhouse gas it is the issue, it is the foundation of life, crop increase etc. The real problem is pollution, plastics, etc. The problem with stopping pollution is that the corporatocracy cannot make money from its waste as easily as charging us all carbon tax..
Yawn. A carbon tax is a tax _for_ the people, not a tax _on_ the people - you get the money back and the polluters pay. It is a Republican idea.
And yes CO₂ is a greenhouse gas and it will destroy civilization in less than a century if not put back where it came from ASAP.
How many trees could they have planted for the cost of development of the fake tree?
No really I'd like to know!! Is this really the plan then? can't we just start using the technologies that exist already to generate power, plant trees and just stop the unlimited plunder? Maybe? Please?

Anything that is boring will not be accepted by the purpose-starved rabble.
The Beatles told us, but the message is way too simple to be accepted: _All you need is love._ It will confuse many people. Confusion being a function of the mind.
@@Dowlphinits love of stuff that's doing us in
We should be rapidly installing forms of automation, if to overcome our industrial disease. We need to become unemployed, or if we dont, we end up returning to the factories and office desks to create yet more layers of carbon to the soupy mix you can see hovering over all the cities that disperses as it travels. We should be focusing on consumer goods that are designed to be reused in multiple ways, taking cues directly from the lego block. You have this phone you might be reading this on, and it doesnt all you to swap out the battery anymore. You can't simply replace a broken segment of it, because it's been designed to end up in the landfill as a entire item rather than only a broken segment of it. It's the industrial disease right there, and without any real afterlife as a backup plan, only a hollywood fake news version of one.
It's time to wise up to the frauds our species has created.
The real issue is that humans require energy and that produces heat. Humans demand for heat is the real issue.
I don't understand why they don't use the same principals they use to produce carbon particles for Co2.
Is it not a case of making bucky balls from carbon dioxide.
Pls make it into carbon fiber. Seems to be too expensive.
You can also put that artificial trees to the out put wholes of cars exhaust.
BBC IS NO MORE BBC
If you can make these CO2 capturing machines really big it may help but it will be very expensive.
plant a tree its cheaper
Extinction is cheap. Survival is expensive and takes effort, but is not compulsory.
@@ahaveland We need to stop cutting down our trees and start planting them.
@@danielmount6928 We do, but it's still only a small part of the solution.
Why robot is in every new tech.
Why humans are not staying underground and grow forest overground? Please point me to some research papers!
You'll be breathing in radon gas. Unless you've got a plan to eliminate it some how.
Go and live without sunlight and then come and tell us it was.
All that international money we give to CERN, should be used on solutions like this to save the planet.
Or billions subsidizing oil and weapons industry?
Just Plant the Tree's Again....
Problem solved....
Plant trees on unused land/......
There is no unused land.
Where there used to be trees is now cities and fields for growing food to feed you.
Restoring forests means giving up beef, soya and corn. etc.
3 trillion trees are missing, but even these could not draw down enough carbon to save us.
@@ahaveland Brother....
little drop of water makes a mighty ocean
There is unused land.
There are so many land where there are little trees or no trees.....
Everything can be balanced........
Think positive.there is always a way.
@@junaidislam3565 Trees don't or can't grow everywhere because of physics.
No amount of positive thinking will change that, only actions, and terraforming the Sahara is impossible or more expensive than all the money in the world.
I suggest you do some research into afforestation and you'll see that it a much bigger problem than you think.
Not everything can be balanced when we have so unbalanced the climate into tipping points that cannot be reversed.
@@ahaveland ok how did we unbalanced the climate.....
By cutting tree's..
you say it cant be reversed so that means you already gave up........
But not us.....
Everything can be fixed.....
Just ask any scientist......
If we start plating the tree's again in unused land...Do you know what is called unused land???
A land where it is fertile but not used by tree's or building.there are so many unused land.....
We can create man made forest if we want...
There are so many technology that people turn dessert into fertile land...
If you don't believe then just search on youtube.......
There is still time and hope......
@@ahaveland ruclips.net/video/cazVrq9v1mE/видео.html
Stop cutting down our trees.
Ok
Okay, then what? We live happily ever after? No. You're in earth.
You should get the Chinese to foot most of the costs, but that will never happen.
yes it can, and Britain is falling behind
Help? Yes.
Is it enough? No. We are doomed.
Too bad this program only devotes seven minutes to the CO2 removal story. That's just enough time to get people completely confused.
Lackner is right that artificial trees are the way to go. The required land area is not a problem, as it is for real trees. But when you listen to Lackner, he's much too favorable to the idea of continuing to use fossil fuels. In that sense, his idea is a bit dangerous. We need to convert to renewables first. Artificial trees are going to need a lot of cheap energy, and only renewables can provide that in the time frame required. So while artificial trees are the way to go, now is not the time to focus on them.
The ideal thing would be to have a place with a lot of industrial activity producing a lot of waste heat that can drive the recovery of CO2 from the ATs, and a good place to pump the CO2 deep underground. Iceland might be a really good site for that; they already smelt a lot of aluminum there with their cheap electricity. And they have geological faults where the CO2 could be pumped deep into the ground. No way are we going to drink enough beer to use all that CO2! (Besides, we would just belch it all out again.)
Ronald Garrison the AI dancing story was more important 🕺
to jump to a ten year advantage would be cripplingly expensive makes everyone do problem pass time games so will the .govt make it work
WTF give that poor guy some protesis.
they are artifical TREES, why do we need those? cant we plant more trees and renev the forests, it also reduces the head soaking of earth and sea... because trees use the suns energy insted of pointing it in another direction... and you can cut trees down and use them, what do you do with these? are they usable infinatly? i dont get why we need artificial trees cant we just plant trees and have forests ??? or is there not enough money in that?
Forests are temporary carbon sinks not a permanent one! If forest catches fire, all the carbon stored for decades would be released in seconds!

TAX THE ROBOTS AND USE THAT TAX TO PAY FOR THIS AND MORE INCLUDING UNIVERSAL INCOME
19:58 - There's still lots of sand in the Sahara... Enough for a City that will cover the entire world
by getting rid of humans
bbc clicking mouse buttons in fancy studio making news making globe warm
if you want to catch CO2 just plant trees OK! No need for techs
And super thick preserved wood buildings to store the co2 , I would be in for genetically modified trees you could live in , If you want a family you have to plant a `tree house` !
Technically, global warming is really bad for humans and our cities, not so much for nature itself as everything will just adapt over time to the changes. If anything the increased CO2 in the air will, in the long term, increase the resources available for trees. Until now, the worlds deserts and grasslands have been pushing back the forests, which at one point covered the planet. Most of the CO2 was locked away, never to be accessed by nature again, but we're reversing this process... at our own long-term expense. This means a world war will happen once there's food shortages or something, war has always been over scarcity. Lets hope we get asteroid mining working soon, maybe we can set up farmland in space and just drop food down to earth?
goofs
Trees...plant billions of REAL trees instead.
No
.. and BBC could shut down and do something worthwhile
What is wrong with innovating our infrastructure and building patterns.......Just build around nature
Gosh.....humans are interesting
BBC equal platforming of climate change deniers has done loads of damage . Well done BBC.
That's not going to help the ice age is going to happen no matter what you do it's happened before in the dinosaur era and Minnie times before you're just trying to make more money haha😁😁😁😂😂😂😜
Yes cos nature produces most of the CO2
what happened to you BBC...sad stuff..
More AGW BS "projects"
Get rid of all of these Nuclear power plants.
climate insanity
this drone is a waste of money, useless. how about a drone that detects drugs, contraband and criminals?
It *is* detecting criminals. Ones that poison your air.
