Warming led to an intensified methane cycle, lasting thousands of years, study finds. New study makes novel use of plant biomarkers preserved in sediment to reconstruct methane cycling over the past 10,000 years Plant waxes hold an isotopic signature of ancient methane As the planet warme

By studying these biomarkers, the researchers discovered that past warming during the middle Holocene caused lakes across a wide range of Greenland’s climates to generate methane. Because methane is a more potent greenhouse gas than carbon dioxide, any changes in methane production with warming are important to understand.
When the research began, McFarlin was a Ph.D. student at Northwestern; now she is an assistant professor at UW. Osburn is an associate professor of Earth and planetary sciences at Northwestern’s Weinberg College of Arts and Sciences. Osburn co-advised McFarlin with Yarrow Axford, William Deering Professor in Geological Sciences at Weinberg College and the paper’s second author.

Ancient plant wax reveals how global warming affects methane in Arctic lakesIn a new study, researchers examined the waxy coatings of leaves preserved as organic molecules within sediment from the early-to-middle Holocene, a period of intense warming that occurred due to slow changes in Earth's orbit 11,700 to 4,200 years ago. They found that warming potentially could lead to a previously under-appreciated flux in methane emissions from lakes.

Atlantic walrus more vulnerable than ever to Arctic warmingPast cycles of climate change, along with human exploitation, have led to only small and isolated stocks of Atlantic walrus remaining. The current population is at high risk of the same issues affecting them severely, according to a new study.
