Pinatubo. https://eos.org/editor-highlights/eruption-and-emissions-take-credit-for-ocean-carbon-sink-changes#.X3yG88CrTDY.twitter Using CaO- and MgO-rich Industrial Waste Streams for Carbon Sequestration Joshuah Stolaroff, Gregory Lowry, and David Keith. 2005. “Using CaO- and MgO-rich Industrial Waste Streams for Carbon Sequestration.” Energy Conversion and Management, 46, Pp. 687-699. -David keith commenting that theya re worth pursuing but not huge Unnatural climate solutions? Nature Climate Change volume 10, pages98–99(2020) Rob Bellamy on why the hype around ‘natural’ climate solutions threatens us all. His new paper is with Shannon Osaka.  Abstract: Framing solutions to climate change as natural strongly influences their acceptability, but what constitutes a ‘natural’ climate solution is selected, not self-evident. We suggest that the current, narrow formulation of natural climate solutions risks constraining what are thought of as desirable policy options. https://www.nature.com/articles/s41558-019-0661-z
