Tracing sources of atmospheric methane using clumped isotopes.
Proc Natl Acad Sci U S A
November 2023
Article Synopsis
- The study utilizes a new measurement technique to analyze different isotopic variants of methane (CH) to understand their origins, specifically from fossil fuels and microbes.
- The results reveal that the actual composition of atmospheric methane differs from model predictions and highlight a significant microbial contribution that had been underestimated in previous studies.
- The findings show that isotopologue data can effectively differentiate between various emissions scenarios, despite consistent atmospheric methane concentration profiles and traditional isotopic measurements.
High COVID-19 mortality among Black communities heightened the pandemic's devastation. In the state of Louisiana, the racial disparity associated with COVID-19 mortality was significant; Black Americans accounted for 50% of known COVID-19-related deaths while representing only 32% of the state's population. In this paper, we argue that structural racism resulted in a synergistic framework of cumulatively negative determinants of health that ultimately affected COVID-19 deaths in Louisiana Black communities.
