Geologic weathering is an important, but slow, part of the carbon cycle in which rocks essentially absorb carbon dioxide. A research team in Iceland has invented a method of creating rocks using carbon dioxide, water, and basalt rock. A chemical reaction among them enables the basalt to absorb the carbon dioxide. A Washington Post article describes the research and its implications, which are told in detail in a new paper in Science.
This definitely qualifies for the “how cool is this” club, and illustrates clearly how creativity, research, and innovation will expand our options for grappling with greenhouse gas emissions.
