Although this process mimics a natural process, it’s not natural in itself.Scientists suggest that rapid uncontrolled changes in pH, carbonate saturation state and dissolved aqueous CO₂ could affect ocean ecosystems.In doing so, the rock surface exposed to the atmosphere is expanded, making more rock available to absorb carbon.īenefits include improving degraded soils and plant growth and helping to reverse ocean acidification. The solution accelerates this process by spreading finely ground rock over the land (farmland, beaches, forests, etc.). In fact, rocks exposed on the earth's surface absorb carbon dioxide from the atmosphere and, in the presence of water, transform it into other compounds, retaining the CO₂ for a long time. But pinning our hopes solely on tree planting is not enough.Įnhanced weathering is a technology that accelerates the natural weathering of rocks by mimicking the process. Protecting and enhancing our forests to ensure that they continue to serve as natural carbon sinks is of the utmost importance. Trees need a lot of area: We would need huge areas filled with new trees – land the size of Europe or twice India. Young trees take in far less CO₂ than mature ones, and that means it could take decades to absorb the required levels of CO₂ this way. Reforestation requires a great deal of water, and, most importantly, time.
