The ocean is the carbon sink that’s reaching a tipping point. If it keeps becoming more acidic and heating up, the plankton will die, oxygen levels drop and we all die.
Limestone rock weathering is how carbon is lowered naturally - usually it happens from an earthquake that exposes these types of rocks. Then over millions of years they suck carbon out of ocean as they weather. Accelerating that process by transporting the rocks to coastal areas with a lot of waves will dramatically reduce carbon. We’re talking carbon removal at less than $20/ton. Nothing else comes close, is as natural, or attacks the problem at the source by going after ocean carbon and acidification.
We need $1 trillion spent yearly on rock weathering and we could avert mass death this decade. We got about 3 years to do it. 2026 is the last chance since El Niño and the sun cycle is at peak that year, after that human civilization is done for.
