Just as adjusting the ingredients in a dish can result in a completely different taste, variations in the substances present in seawater can significantly alter the binding of CO, is formed by the breakdown of rocks and their subsequent entry into the ocean. An increase in erosion on land leads to more weathering of silicates and carbonates.
If warming continues slowly, alkalinity would drop by up to 68 percent by 2100, depending on the watersheds. That means the ocean’s ability to sequester COwould decrease significantly. Rapidly progressing warming, on the other hand, would lead to higher temperatures and thus more precipitation in temperate climate zones. This would increase alkalinity by up to 33 percent. “But that doesn’t mean that more emissions are good for the climate.
Climate change is greatly accelerating the interplay of carbon cycling and weathering that is fundamental to the development of life. The team first looked for existing data. The goal was to find as many alkalinity measurements as possible in the immediate vicinity of erosion measurement sites. To do this, the researchers searched databases and publications and took samples themselves. They conducted the investigation of the alkalinity factors using their new model.
