How do we reduce the impact of climate change, and could geoengineering be the solution? Host Sinead Bovell is joined by sci-fi writer Kim Stanley Robinson and other experts to examine the goal of Global Net Zero Emissions, direct air capture strategies, and why geoengineering is a risky strategy - that may be our only hope.
Thank you to Romany Webb, Maria Lopez-Nuñez, Gregory Nemet, and Ugbaad Kosar for contributing to this piece.

I find it odd the lengths that we may go to minimize the effects of climate change. Some of them seem to be more difficult than weaning ourselves off of fossil fuels.

I think direct carbon capture from the air is a terrible waste of funding, energy, and materials that could be spent on developing energy efficiency, renewables, and alternative carbon capture methods. The "direct from air" carbon capture process is massively inefficient compared to other methods of carbon abatement. It also reeks of the "clean coal" propaganda machine, and IMO it's the only reason we know / think about it at all.

I agree with @Algormortis9. DAC is horrible at being efficient. IIRC the last number I read is 1% of the amount of the captured CO2's binding energy combined . BECCS is much more possible in this regard. DAC will only work if we have a ridiculous surplus in green energy production.

The obvious appeal of geoengineering is that it gives people a straw to grasp, since people, governments, and corporations aren't, by and large, willing to do the hard work that is otherwise necessary to stop climate change before it becomes an unmitigated disaster. However, the risks involved with intentionally monkeying with the planet's thermostat (as opposed to what we've been doing, which was, at least at first, unintentional) may be higher than just adapting to climate change.

We could mitigate much of the harm of excess atmospheric carbon by changing farming,. This also means changing our buying habits to force big companies to change how and what food is grown. Eating foods from biome appropriate, polycultured, alley-cropped (because alley-cropping makes better use of soil depth, sunlight, minerals, etc, and it mimics the most productive places on earth, savannas), food and biomass-producing (livestock feed, etc) perennials and grasses alternating with interplanted trees, vines, and shrubs. This reduces chances of crop failures due to droughts, heat waves and flooding, builds soil, increases nutrition, localized food, and builds resiliency. It sequesters a lot of carbon for free while also helps reduce grid strain from pumping water. It helps aquifers to recharge, relies on natural pest control, increases diversity of food available to the world market instead of relying on a fewer food varieties. Instead of managing it with shipped-in inputs like petrochemical fertilizers, weed killers, pesticides, dumping culls, burning crop residues, etc, manage it with livestock instead. This mimicks nature. It turns production costs into production profits, while producing even more food in a wildlife friendly way. Animals pastured on diverse plantings and weedy pasture have higher nutritive value than grain fed animals, deepening nutrition for both livestock and the nutrition of their products. Thus is simple, highly effective and much much cheaper than pumping carbon into the ground, ax well ad more useful. Carbon sequestered into the soil by plants improves the soil, making it easier for more regreening, as well as increasing water sequestration, reducing the need for irrigation, plowing, and high tech, high cost, low return solutions. Look up Mark Shepard for more detailed information on restoration ag. If we accompany this type of agriculture, called restorative ag (not to be confused with the more general term regenerative ag), with highly localized (onsite) rainwater harvesting through detention ponds, swales, onsite materials, etc we increase the opportunities for food production, regreening, carbon capture, reclamation etc, at very low cost as these can be quite durable when well placed, and well built. India has regions that are implementing this at scale and transforming huge swaths of low production land, while avoiding the need for pumping water. Look up Brad Lancaster's books on Rainwater Harvesting in Drylands and Beyond, latest editions for best info on building water resiliency. Andrew Millison has done a lot of work documenting rainwater harvesting projects in India, they are good videos to watch. The third thing to do is put in a lot more rail especially publicly owned rail (though the companies can remain private). This is will make moderate long distance travel easier, cheaper, increase accessibility, reduce the costs of shipping goods, etc. If you make rail something the rich want to travel on, it will mean better rail service overall. Rail can have definite advantages if it is dense enough. Restroom breaks, internet, napping, avoiding driving, air travel anxiety, and TSA lines are all excellent reasons for trains to ge our best future mode of travel. Rail is something we need to push our politicians towards, instead of dubious electric rebates for rich people... High tech solutions are just a money grab to further enrichen and empower globalist elitists.

What many in this comments section are ignoring is that we are rapidly reaching the point of no-return. Extreme measures would be needed for us to avoid this; measures that are not politically realistic even in the most optimistic scenario. Geoengineering is therefore an inevitability, and environmentalists must accept that if they want to have any say over how it is done. Thus they would do better to ensure that geoengineering and carbon sequestration projects are coupled with de-carbonization, rather than lobbying against all of it.

Even if we had a magic solution to climate change, it's not the only existential threat to humanity right now. Besides climate change there's biodiversity loss which gets worse with climate change but there a more important causes such as direct destruction of ecosystems, invasive species, pesticides, etc. There's also the microplastic problem which's consequences are not even completely understood yet. Super-bugs and viruses because of animal agriculture. And well you can include the ever-existing threat of nuclear annihilation.

There are simple solutions but the economy is far more important. Direct air and geoengineering are there to make money. They will work but at what price and who gains?

The trend line leads to global meltdown. We're going to see a rapid escalation in the number and severity of extreme weather events. The American southwest is already seeing dry heatwaves leading to droughts, wildfires, changes to planting regions, states in conflicts over water and electricity, possible abandoning of desert cities. The American east & gulf coast will see intensified hurricanes, changing rain and tornado patterns, flooding, tropical disease spread and deadly wet bulb temperatures. The famines, wars over water, uninhabitable earth, climate refugee crises and biodiversity crash that global meltdown is affecting in much of the rest of the world will come here as well. These problems are only going to get worse as climate meltdown accelerates. If sufficient action isn't taken now to bring atmospheric carbon dioxide from 420 parts per million to 350 parts per million, the primary cause of global warming, and I mean the kind we're not even considering, it's out of humanity's hands by 2027.

In fact last time it was de-desertifying was the Eemian (PBS has vid on it) 116kya Was +1 over 2020 Temps and trees pushed into west Texas American desert has been drying for most of the last century. And a desert. No one who moved there expected Ozark ecology. Last years monsoon was just above average at 8" There will be droughts. GW causes more aggregate global rain. In NorthAm it will mostly precipitate in winter and summers be hotter. I'd prefer agroforestry as low tech solution since their roots can go further than any annual grain or Table vegetables. Irrigation improvements to be both Israeli point-drip and tractor friendly for 1st world and really cheap for 3rd.

Every farmer was producing much as they could to get money in case drought got them next. We had oversupply, as far as capitalism is concerned. Give away oranges to poor then no one buys them... separate convo As is general environmentalism. We'd have not two trees in eyesight of each other if had steam engine but never made sense of coal. Continents be all perennial switch grass or something. Clouds of a few species of birds. If we'd done biodiesel as basis for everything we'd still be overfishing and teak furniture. It's not all one thing. No premier Polar mammal or bird is critically endangered as a taxonomic family. 13/18 🐧 species are solid. Polar 🐻‍❄ is solid for now. 2 types of puffins are Vulnerable. Rest not listed. Beavers are a menace expanding so fast into Arctic little more as the summers grow. No longer need trees; use taiga shrubs. Nothing bad has happened, yet, at least.

The answer is to stop burning things! Also to implement massive govt programs (not just offer incentives) to have the govts make and give away solar panels, along with developing the supply chains needed to do so. Thegovts need to declare a State of Emergency and use imminent domain and take over private businesses to make this happen. Govt loans or grants to install solar in private homes and the converting of all homes to use electric heat pumps. Overall this would be much cheaper to implement than to finance multiple bandaid solutions to remove CO2 from the atmosphere all the while continuing to belch out carbon from fossil fuels. Sure we also need to remove CO2 from the atmosphere if possible BUT putting as much of a full stop on emissions as is possible is priority number 1.

Most people don't know that most underground mining equipment is already using electric induction motors as it removes the problem of exhaust and lessens issues with hot engines causing vapor ignition. But even if some fossil fuel is used to do the mining, as the end solar goes online there will be a corresponding reduction in fossil fuel burns in power plants that will offset that used to do the mining. Eventually the fossil fuels will be completely replaced as everything becomes electric using the solar as the source. Overall this will result in less fossil fuel burning quicker and will ultimately end most of it for good in the power generation industry.

We only need to reduce rolar radiation by around 1% to get back to pre-industrial temperatures, which could be acieved by injecting just 5% of the sulphur that has been cleaned out of coal and shipping emissions into the stratosphere. It will last longer (a couple years) before having to be replaced, and cause considerably less health issues and acid rain than the unintentional emissions ever did. % reduction will have very little effect on plants and solar power. The added cooling will also be beneficial since solar panels are more efficient when cool, and photosynthesis is more efficient when the plants are not on fire.

Hey... so I agree with what you are going for here in this video, but if you want to convince people don't use a science fiction novelist as contributor (or pick almost any other title). You could be speaking 100% truth, however, if you are backing that truth up with a "well known conspiracy theorist" (as an example) then it is hard to take you seriously. A bad move to decrease the public trust for the Public Broadcasting Service.

There is enough Co2 in the atmosphere now that even if we completely stopped this minute , it would last something like 100 years. The governments around the world should have forced oil companies long ago to develop the technology to clean up the mess they created instead of taxing the helpless consumers who really don't get any choice. Another problem is the methane that is being released due to thawing. It is a much more potent green house gas and will cause a much faster rise in global temperature.

It doesn't solve everything, but the biggest problems we face today are rooted in the increase in temperatures. Climate change effects will piledrive our economies to the point where decarbonization just doesn't happen. Climate cooling methods like solar geoengineering can buy us time to get things under control and change our ways, but none of the problems you listed will be fixed if we don't do it. We're gradually realizing just how badly we've shat the bed, and we need these solutions despite the side effects, since the side effects of not doing it is so much worse.

@@cheweperro Haven't seen anyone proposing it as 'the' solution yet. But let's say hypothetically that if you were terminally ill, and the illness would take time to cure, and there's a medicine that can keep you alive until the illness can be cured. The medicine itself will not contribute to curing the illness, and carries unpredictable side effects. But since the alternative is certain death. Wouldn't you be willing to make that gamble? Shouldn't this medicine at least be a 'part' of the solution, as a package deal, like how they use chemotherapy to kill cancer. Nobody 'likes' chemotherapy, but it's either that or death. A lot of people are waking up to the climate crisis these days, and due to el nino, there's gonna be a heck of a lot more of that next year, and nowards. We won't be able to geoengineer the climate at scale for a few years, and by the time we've begun, there's gonna be a huge amount of people pushing for actual change in our system. I admit, it's possible I am too optimistic here, but you have to believe in a better tomorrow in order to put in the effort to make it so. And right now I'm unable to see another option than doing geoengineering if we want to have any kind of future.

You've missed the point entirely. If we were just talking about a few icebergs here and there, there'd be nothing to talk about. When we're talking about the entire ice sheets of Greenland and Antarctica that's another thing entirely. The reason is that those ice sheets AREN'T currently in the water. As they melt and that water heats up beyone 4 degrees centigrade, the water expands. And there's a TREMENDOUS amount of water locked up in those ice sheets. So why hasn't the Statue of Liberty sunk already? Because it takes a pretty long time for those ice sheets to melt completely. But the process takes on its own momentum once it's been started. And the process is well underway. Live near the coast? I hope you like swimming . . . .
@JoshJones-37334
@JoshJones-37334 7 месяцев назад
It IS sinking (relative to sea level) and your science experiment is flawed. Sea water has salinity. Fresh water is more dense than sea water. So, when floating ice melts and becomes liquid, it takes up more volume than the seawater it displaced when it was ice, raising sea level. This has about 3% the effect of grounded ice-melt and raises sea level.

The only way to let the planet “do its thing” is to either come up with solutions to help tackle the extra carbon and help out the plants…or we eradicate humans. And I don’t think a majority of people would go for the second option. Though if we don’t do anything, then I suppose the planet would just do its thing anyway by making this place so uninhabitable for humans that we go extinct. Eventually, the planet would bounce back, but we most likely wouldn’t, and it would be a new era of a new dominating species.
