Can Geoengineering “Undo” Climate Change? I NOVA I PBS
It might be too late to prevent every climate-change-related catastrophic event from happening. But there is a way to reverse some of the damage from our emissions.
Discover how geoengineering solutions — from techniques as natural as planting trees, to vacuuming CO2 out of the air, to science-fiction alternatives like blocking sunlight — can help humanity turn the tide on climate change, and why these approaches are controversial.

Yes another way is to remove profits from our society. Unite as a human race. Each country has something to offer. 😊

Can RFK and MUSK shed light on the musical instrument that is manipulating the atmospheric river and weather? And its correlation with the crazy storms, HURRICANES, TORNADOES, WILDFIRES, AND EARTHQUAKES Have musk look into our governments involvment and how much taxes get SPENT causing disasters?

AGI will come up with the solution, and the fusion power will provide needed energy to geoengineer the planet in vast scale in the future. Unfortunately, we will experience catastrophic consquences of climate change first before that happens.

We knew it for years. Now they are pretending it hasen’t happened yet to get us all used to the idea of it and pitch it in a good way, just like the NWO is now WEF.

This is a lie to cover up the truth that "climate change" isnt the geoengineering that has caused it and only "gives permission" for these weather war manipulations to finish us off. I live in alaska and it is getting warmer and warmer, trees are dying in mass and the aurora is rarely seen any more because the WEF global elite with bill gates funds the creation of catastrophic weather patterns that destroy property, crops, trees, bugs, birds, and people so the WEF can make us "own nothing and be happy!" They pretend to give the earth a "cure" but it is the cliff they force us to jump off of or die if we dont listen to them! They are destroying the ozone layer to cause more and more UV light to hit the earth and kill more life. See Dane Wigingtons geoengineering channel that tells the truth!

It is not only killing humans slowly but also killing the planet by eliminating life giving sun rays. So NO it is not helpful in the least! They do a great job of trying to convince us though. Did anyone know that they have been spraying chem trails since the 1930? I challenge all to do some digging!

Nice trolling, it literally caused all the problems, twenty years of spraying poisons… "con-trail" (yeah nice gaslighty con there). Typical narcissist tactics, harm everyone then gaslight them when they realise, then invert the reality and call the abuse "help". Disgusting.

Climate intervention operations have been going on for 30 plus years. Geoengineering is no answer, and was never intended to make matters better. Look up and see the damage being dished out daily. This is weaponized weather they can drought us or drown us. It’s nothing personal they just want most of us dead. They have created a new religion for the masses climate everything. How is it working for you now.

If co2 is such a problem, why do they put it in beverages, I hear a can of soda has 2+- grams of co2 in it

Can’t we just build a huge direct-air-capture with 50 million units? Or isn’t there a type of miracle bleach that, if added to the sky 🌌 could suck up 🆙 all the CO2 we’ve emitted into the atmosphere but more than that, reflect the suns rays back into space? What about using CW-7 in the movie 🎥‘Snowpiercer”? Does that cooling agent exist in real life?

Its funny how they don't mention anything about the volcanoes around the world and how much CO2 they give off , volcanoes put off a 100×'s more CO2 then humans combined .

You people are insane how are you idiots going to reverse something by doing more of the same thing that caused the problem in the first place. Also what about atmospheric testing and stop pretending that climate engineering hasn't already been going on for seventy years.
@TheRoguelement

This idea we can undo anything is Insanity…now we have the deep state telling all the propaganda tools they own to get going with the Hard sell get it out there ..but it wouldn't how many trees you planet because the fall out from SAR program has made growing anything nearly impossible…the only way we can win is if we rip out by the roots the disgracefully obscene power structure that has brought us to our knees now. This is a stroke job beyond comparison..

Kinda funny that Aluminum Oxide is what they use to Geo-engineering because I guess the democrats thinks that Novel Virus in the stratosphere because AO Nano Particles is being sprayed. And also the main ingredient in 3 of 4 jabs. Why is that? They wanna control the weather and also control you. And our country also signed the Nuremberg Act, did that stop them from violating it? Or violating the United States Code? Specifically 26 USC 4132 (a)(2) #breakoutcases Or infringing on the Bill of Rights? Been doing a lot of studying who governments across the world did this to also increase radio frequency mainly the lower bands but not limited to that. Just so happens that 5g runs optimal on low frequency radio waves. That the jabs when ionizing how they can react to RF’s and SDR? We must be all conspiracy theories right? I guess you got to get big pharmaceutical companies to pay double to media companies to keep fact checking to play damage control. Because this is about how to get CO2 down right? By eliminating people, the service that people use, the energy the services use, and the CO2 per unit of energy! #americanstiredofcensorship

More albedo and the Earth cools.
Less albedo and the Earth warms.
No albedo and the Earth cooks.
That is NOT what RGHE theory predicts.
The earth is cooler with the atmosphere/albedo not warmer.
The “extra” warming energy downwelling from the GHGs originates with the surface upwelling that “extra” energy as a BB. As demonstrated by experiment, that is not possible.
https://principia-scientific.org/debunking-the-greenhouse-gas-theory-with-a-boiling-water-pot/
If either of these points stands, greenhouse theory fails and man caused climate change collapses.

Climate change has always been in a wave, that waveform hasn’t changed at all.. we are just below a peek and that will die down again and so on!

I remember when PBS used to be a lot better, back in the 70s when I was a kid. Now it is propaganda like NPR. Sells dangerous ideas that globalist billionaires want to plant into the minds of a gullible public. Geoengineering is in fact this: the use of products from the mining, chemical and petroleum industries to "solve" the problem of pollution caused by the mining, chemical and petroleum industries.

I think the answer will ultimately be a combination of multiple ideas. Like a shot gun. But all the ideas need to be good ideas.

Sometimes I really question the editing in that you give some really bad images or incongruous images or images somehow not matching the dialogue. This can cause a drop in concentration. For example, the last video of flooding shows a family walking in the flooded area when it is unnecessary. The eldest male is not walking in the water. Poor editing choices.

Funny, a month ago I read that their experiment this year failed. I wrote one of the involved scientists and explained why it would fail. It simply does not stop or slow down the CO2 number because it constantly get bigger as the population is growing, no doubling every 38 years. It's people who breathe out CO2. I also asked them if this shield would possibly reflect the heat back to earth and just make things worse?

Thanks PBS Nova 👍
Putting more crap in the atmosphere is NOT the answer. Industry & Big OiL already know the solution. Their just too greedy to do anything to correct the problem, unless government's unite globally and force them. Because most manufacturing is done in Asia, with cheep coal to run power plants, I don't think anything will be corrected soon. Solar power is our best answer.
