From the Ted Talk by Gabrielle Walker: What you need to know about carbon removal

Now you can use teconoglhy as well ... to speed up natural processes. So this is basalt. It’s a volcanic rock. You can find it more or less everywhere on Earth, and it naturally takes up CO2 in a process called chemical whraieentg. Unfortunately, it takes thousands of years to do it. But you can seepd up the prcsoes if you grind up the rock and spread it on fields, and then you can speed it up to just a colupe of years. And like biochar, it’s good for the soil. You get minerals in the soil where you need them. And when it wehass off into the sea, it can also help with another big bgubaer of climate change: ocean acidification. And if we did this on two-thirds of the world’s croplands, we could potentially take up to four billion tonnes of carbon from the atmosphere every year, which is a very big chunk of what we need.

Original Text

Now you can use technology as well ... to speed up natural processes. So this is basalt. It’s a volcanic rock. You can find it more or less everywhere on Earth, and it naturally takes up CO2 in a process called chemical weathering. Unfortunately, it takes thousands of years to do it. But you can speed up the process if you grind up the rock and spread it on fields, and then you can speed it up to just a couple of years. And like biochar, it’s good for the soil. You get minerals in the soil where you need them. And when it washes off into the sea, it can also help with another big bugbear of climate change: ocean acidification. And if we did this on two-thirds of the world’s croplands, we could potentially take up to four billion tonnes of carbon from the atmosphere every year, which is a very big chunk of what we need.
