developed to avoid emitting the CO2 produced by using fossil fuels (carbon capture and storage) or to take the CO2 back out of the atmosphere (carbon dioxide removal). Both these technologies have so far failed to deliver. And, since fossil fuel power plants or industrial facilities can have lifetimes of fifty years or

the globe to continuously spray large quantities of sun-blocking aerosols into the stratosphere, or to cover extensive areas of Arctic ice with glass beads. Carbon dioxide removal at geoengineering scale includes suggestions to fertilize swathes of the ocean to cause massive algal blooms, or to convert enormous land areas to tree plantations

…

cuts, industrial greenhouse gas removal will be needed to keep global temperature increases below both 1.5°C and 2°C. Scientists have studied atmospheric carbon dioxide removal for more than a decade, the twin steps of capturing carbon dioxide from the air and storing it out of harm’s way. Plants, rocks

…

that naturally sinks to the deep sea sequesters around 200 million tons of carbon per year globally; farming, then deliberately sinking, kelp is a promising carbon dioxide removal opportunity. But instead, what we currently have is up to 1 billion tons (1 gigaton) of carbon dioxide being released annually from degraded and destroyed

Nomad Century: How Climate Migration Will Reshape Our World

by Gaia Vince · 22 Aug 2022 · 302pp · 92,206 words

some of the southern places made uninhabitable by climate change may become once again liveable through geoengineering innovations that reduce global or regional temperatures, through carbon dioxide removal and technological interventions that can cool large areas cheaply. Truly, this is the century of unprecedented, planetary human movement. We need to plan pragmatically now

be crushed into a highly reactive powder that can be spread on agricultural fields, where plant roots and microbes in the soil speed up the carbon dioxide removal. The powder is also an excellent way to add minerals to soils, boosting nutrient levels,11 improving crop yields and helping restore degraded agricultural land

could have been released to periodically “top up” the warming, perhaps for as long as a billion years or so. As Martian volcanism died down, carbon dioxide removal would have been greater than its replacement. The planet would have been warmer only at its equator and in the lowest regions where the atmosphere

What If We Get It Right?: Visions of Climate Futures

we have ever built. It’s just incredible. In order to take that out, we are going to have to have a conversation about artificial carbon dioxide removal. That essentially means building machines that suck CO2 out of the atmosphere (aka artificial trees). Or “rock weathering,” which is spreading rock dust over cropland

atmosphere for a really, really, really long time. Ayana: Like hundreds of years. Kate: Hundreds, maybe even thousands of years. But when we talk about carbon dioxide removal, there is a justifiable fear that it is going to create a moral hazard, that it’s going to be used to justify continued burning

of fossil fuels. Ayana: That’s not gonna work. Kate: No, because when we talk about carbon dioxide removal solutions, those are limited by physics. In order to separate out what is essentially a very powerful but trace gas in the atmosphere takes energy

…

. There is simply not unlimited energy to do that. So when we talk about getting it right, we have to think about carbon dioxide removal in terms of removing what is already there, as opposed to allowing it to compensate for future emissions. Ayana: Thanks for laying that out so

to welcome to its ranks nations that make such commitments, especially if they also commit to the development and deployment, over time, of technologies for carbon-dioxide removal. As new members of the Concert, those acceding nations get a say in decisions about revisions to the veilmaking plan in view of new monitoring

…

some particularly sensitive areas liming programmes designed to reduce the effects of the decreased alkalinity – programmes related to some of the more successful efforts at carbon dioxide removal – are having some success, though at significant expense. In other places, due sometimes to poor implementation and sometimes to unforeseen circumstances, they have failed. The

could reverse global warming.” When good land management practices create a ton of carbon in the soil, that represents slightly more than 3 tons of carbon dioxide removed from the atmosphere. Lal believes that 3 billion tons of carbon can be sequestered annually in the world’s soils, reducing the concentration of carbon

the radical to the mundane. They also differ in their cost, speed, scale, readiness and risk. The two main approaches to geoengineering are carbon dioxide removal and solar radiation management. Carbon dioxide removal strikes at the root of the problem, removing the carbon dioxide from our atmosphere and thus taking away the source of the heating

hits the surface. It is an attempt to offset the warming effects of the carbon dioxide by cooling the Earth. It is typically cheaper than carbon dioxide removal and quicker to act, but has the downsides of ignoring other bad effects of carbon (such as ocean acidification) and requiring constant upkeep.

. The conference adopted terminology from an influential report by the Royal Society, noting that geoengineering comes in two major forms—solar radiation management (SRM) and carbon dioxide removal (CDR). The view emerged that carbon dioxide projects would necessarily be slow and in most cases benign and therefore in less need of global regulation

investor, estimates that the technology is still decades away from being taken to scale. “There’s no way you can do a useful amount of carbon dioxide removal in less than a third of a century or maybe half a century,” he says.65 As always with matters related to climate change, we
