"Historical Plagues' Impact on Earth's Atmosphere"

Scientists studying Antarctic ice cores have found a connection between past levels of atmospheric carbon dioxide and global pandemics over the past 2,000 years. The Law Dome and West Antarctic Ice Sheet (WAIS) Divide ice cores show discrepancies in their measurements of CO2 levels, with the Law Dome core indicating a rapid decrease around 1610 CE, possibly due to human population decline and reforestation. However, a new study suggests a more gradual decline in CO2 levels, supporting the idea of large-scale land use changes following the New World-Old World contact. This research sheds light on the potential impact of historical pandemics on Earth's atmosphere and climate.
