This research investigates methane emissions from restored marshes as a climate solution. While marshes sequester CO₂, their methane output varies widely. By measuring emissions and environmental factors, the study examines how interactions influence outcomes, highlighting that restoration can aid climate mitigation but requires deeper understanding to ensure effectiveness.

This research develops stable-isotope tools to measure how microbes—the Earth’s “lungs”—breathe CO₂ in and out. Microbes are massively abundant and shape global climate. Findings show deep subsurface environments slowly emit CO₂, a process that may influence future climate dynamics as human-driven environmental changes accelerate.
