Michel
A new analysis from INSTAAR's Sylvia Michel, Jianghanyang (Ben) Li, and collaborators investigates the root cause of a recent atmospheric methane spike. While their finding suggests microbes have been emitting more methane than fossil fuels in recent years, reducing fossil fuel consumption remains key to addressing climate change.
INSTAAR is pleased to announce that Sylvia Michel is the first recipient of its Outstanding PRA Award. This new award recognizes a professional research assistant (PRA) who has demonstrated excellence in their role and within the larger communities of INSTAAR and the University.
INSTAAR and the Dairy Arts Center collaborated on our second Art and Science Connections Collider on April 10th 2023 during Â鶹ӰԺ Arts Week. The event began with a tour of INSTAAR’s Stable Isotope Lab (SIL) that included a look at actual ice cores from Antarctica and Greenland and a demonstration of how we analyze greenhouse gases in atmospheric samples. After the tour, the group had a general discussion in the Bartlett Science Communication Center.
Researchers from Imperial College London have performed new measurements using data from INSTAAR's Stable Isotope Lab (Sylvia Englund Michel). They found London produces 30-35% more methane than previously thought. Previous estimates suggested 25% of London's methane is from natural gas leaks, but the new study says it's up to 85%.
The sudden and sustained rise in atmospheric levels of the potent greenhouse gas methane since 2007 has posed one of the most significant and pressing questions in climate research: Where is it coming from? Now a research team has tested the leading theories for surging methane levels by analyzing the stable carbon isotope ratios (δ13C-CH4) from methane captured in a large set of global air samples to determine if one of the theories is more feasible than the others.
In INSTAAR's Stable Isotope Lab lie rows of metal flasks holding clues to the cause of an alarming rise in a powerful greenhouse gas. They contain samples of air from around the world that Sylvia Michel‘s team of methane detectives analyse to reveal whether the gas came from burning fossil fuels and wood, or from wetlands and cow guts.
