Baked into the net-zero model is the assumption that we will use carbon-negative tools and techniques to offset areas of life that are difficult to decarbonize. What kind of tools are available to us, and how should their ability and potential fit into our understanding of carbon solutions? Kiran and Leslie Anne discuss advanced weathering, a nifty way to pull carbon from the sky and turn it into rock with - wait for it - green beaches, challenges that currently face carbon-negative tech startups, and the moral imperative to explore the potential of carbon-negative tools.
