Scientists seek to turbocharge a natural process that cools the Earth

Terradot, a carbon removal company, is using “enhanced rock weathering” to sequester carbon by spreading crushed volcanic rock over farmland.

STATE OF SÃO PAULO, Brazil — Across vast stretches of farmland in southern Brazil, researchers at a carbon removal company are attempting to accelerate a natural process that normally unfolds over thousands or millions of years.

The company, Terradot, is spreading tons of volcanic rock crushed into a fine dust over land where soybeans, sugar cane and other crops are grown. As rain percolates through the soil, chemical reactions pull carbon from the air and convert it into bicarbonate ions that eventually wash into the ocean, where the carbon remains stored.

The technique, known as “enhanced rock weathering,” is emerging as a promising approach to lock away carbon on a massive scale. Some researchers estimate the method has the potential to sequester billions of tons of carbon, helping slow global climate trends. Other major projects are underway across the globe and have collectively raised over a quarter-billion dollars.

As governments around the world fall woefully short of their emissions reduction targets, there is a growing consensus that large-scale carbon removal will be necessary to avoid some of the worst effects of climate change. An analysis conducted by an international team of researchers estimated that the world may need to remove up to 10 gigatons of carbon dioxide a year by 2050 to limit warming to 1.5 degrees Celsius — an amount greater than the annual greenhouse gas emissions of the United States.

Shawn Benner, a hydrogeologist and geochemist who left Boise State University after more than two decades to join Terradot, said he made the decision by asking himself what his grandchildren would want him to do. “Not too many people have the opportunity to change the temperature of the...”

that they take all possible precautions, lest they go too far and lead us to another ice age and the cure turns out worse than the disease.

The goal here is poulation reduction

spreading fine dust of volcanic rock is potentially a good way to reduce the population of farm workers/farm families/harvestors. Long-term exposure may lead to serious lung diseases.

Acid rain then releases the co2. But the scam is worth investing in all the same Al Gore. Big money!
