On the evening of February 22, 2020, a carbon pipeline ruptured outside Satartia, Mississippi. Rachel Garner was one of the first to see the thick cloud of carbon dioxide gushing toward her town, and to warn her neighbors. She tells the story of that perilous night, when the entire town and neighboring countryside evacuated. Dozens ended up in the hospital, though there were no fatalities. Local authorities say that if the incident had occurred later when people were sleeping, few would have survived, because condensed CO2 is heavier than air and displaces oxygen at the ground level.
