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!

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.

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...

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.

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.

@@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.

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.

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.

The good news is that our beautiful planet will survive and thrive even if we extinct ourselves through stupidity.

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.

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.

Where otherwise we would have to keep seeding the clouds.

@@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? Why? We've got nothing to lose at this point. What are you scared of?

"Chem-trails" are actually just vapor trails from the full water injection jet engines of large air-transports and airliners. Steam in the exhaust. 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. Superstition fails.

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.

This is NOVA and PBS on their most dishonest mission I've ever seen. It is expensive to remove co2 from atmosphere. If it were subsidized half as much as corn ethanol, then it would be more profitable in the next 5-10 years. You can actually CREATE car fuel from this extracted co2.... rather keep recycling the existing atmospheric co2, and stop pumping extra from the ground. ALSO, the ocean is a huge co2 sink. It is uncertain exactly how much, but it's not a small number

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.

SamytheGreek, Even though ice and snow appear white to the human eye, when examined under powerful microscopes ice and show contain microscopic carbon particles. The reason scientists take ice core samples is to count the parts per million (PPM) of carbon particles to ice and snow. The depth of the core sample gives scientists a timeline to compare the presence of carbon at different dates. There is a noted increase of carbon particles to ice starting from the industrial revolution. As more carbon gets pumped into the air, more carbon particles collect in the core samples. Pure ice and snow will reflect sunlight but the microscopic carbon particles imbedded in the snow begin to absorb heat radiation instead of reflecting it. Once a tipping point is reached with the PPM of carbon, the ice and snow begin to melt. This set the chain reaction in place for climate change. The polar cap began melting several decades ago causing the level of the great lakes to rise and the temperature of the ocean to increase. This, in turn changed global weather patterns on the entire planet. PHD

I find it incredibly hard to believe scientists can predict climate 100 years in the future, but they can't give me an accurate weather forecast 2 days ahead, when the climate prediction 100 years in the future has about 1000x the variables of the 2 day forecast

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.
